Decompose when there is a clear + focused module to extract. +- Avoid new core dependencies. If a dependency is only needed for optional + provider, tool, or integration behavior, put it behind the relevant extra. + +## Typing And Imports + +- Type public APIs and cross-module contracts. Prefer explicit Pydantic models or + typed structures over ad-hoc dictionaries at boundaries. +- `cast(...)` and `assert ...` are acceptable for real type narrowing. Broad + `# type: ignore` comments are not. +- Keep `Any` contained to genuinely dynamic payloads such as provider JSON, + metadata, or third-party integration blobs. +- Keep imports at the top of the module. Use inline imports only for an existing + lazy optional-dependency pattern or a documented circular-import constraint. +- Use `TYPE_CHECKING` imports for type-only imports that would otherwise add + runtime dependency cost or cycles. + +## Testing Expectations + +- Add or update focused tests for behavior changes.

You get back a `Run` per rollout. +A task is an async generator: yield a **prompt**, receive the agent's **answer**, yield a **score**.

Converting is worth it: the v6 spec removes most of the tool-wiring boilerplate. + +## At a glance + +| v5 | v6 | Notes | +|----|----|-------| +| `Environment("name")` | `Environment(name="name", capabilities=[...])` | positional name still works; declare capabilities up front | +| `@env.scenario("count")` | `@env.task()` | same `yield prompt` then `yield reward` generator | +| `@env.tool` / `env.add_tool(ComputerTool())` | a **capability** (`ssh` / `mcp` / `cdp` / `rfb` / `ros2`) | the agent's harness brings the tools now | +| `env("count", word=...)` | `count(word=...)` | keep the `@env.task` return value; calling it builds a `Variant` | +| `task.run("claude")` / `hud.eval(task)` | `async with variant as run: await agent(run)` | or just `hud eval tasks.py claude` | +| `env.run(transport=...)` | `await env.serve()` / `hud dev` / `hud deploy` | v6 serves a control channel, not MCP | +| `.slug`, `.columns` on a task | `.slug`, `.columns` on the `Variant` | unchanged | + +The CLI you already use is stable: `hud init`, `hud dev`, `hud build`, `hud deploy`, `hud eval`, and `hud sync tasks` all carry over. + +## Walk through a conversion + +Here's a small v5 coding environment — a couple of tools and one scenario: + +```python title="env.py (v5)" +from hud import Environment +from hud.tools import BashTool, EditTool +from hud.native import BashGrader + +env = Environment("coder") +env.add_tool(BashTool()) +env.add_tool(EditTool()) + +@env.scenario("fix-tests") +async def fix_tests(target: str = "tests/"): + answer = yield f"Make the tests in {target} pass." + yield await BashGrader.grade(command=f"pytest {target} -q") +``` + + + + +This is the biggest change. In v5 you registered tools and the environment forwarded them, translating per provider. In v6 you declare a **capability** — a connection — and the agent's harness attaches its own tools to it. Shell and file tools become an `ssh` capability backed by a `Workspace`, which you start in an `@env.initialize` hook: + +```python title="env.py (v6)" +from hud.environment import Environment, Workspace + +ws = Workspace("/workspace") +env = Environment(name="coder", capabilities=[ws.capability()]) + +@env.initialize +async def _start(): + await ws.start() +``` + +Other tool kinds map the same way: a browser becomes `cdp`, full computer-use becomes `rfb`, a robot becomes `ros2`, and any custom MCP tools become an `mcp` capability via `Capability.mcp(name=..., url=...)`. You no longer hand-wire `ComputerTool()` / `BashTool()` or call `env.as_claude_tools()` — the harness does that. + + + +The generator body is identical — `yield` a prompt, receive the answer, `yield` a reward. Just swap the decorator and keep a reference to the returned `Task`: + +```python title="env.py (v6)" +from hud.native import BashGrader + +@env.task() +async def fix_tests(target: str = "tests/"): + answer = yield f"Make the tests in {target} pass." + yield await BashGrader.grade(command=f"pytest {target} -q") +``` + +`@env.task()` also accepts `id=`, `description=`, and optional `input=` / `returns=` types (surfaced as JSON schemas in the manifest). The v5 scenario options (`chat`, `returns`, `exclude_tools`, ...) still parse through the compatibility layer if you keep `@env.scenario`. + + + +`env("fix-tests", target="tests/")` becomes a direct call on the task function. It returns a `Variant` — the runnable unit — and `.slug` / `.columns` work exactly as before: + +```python title="tasks.py (v6)" +from env import fix_tests + +easy = fix_tests(target="tests/unit") +easy.slug = "fix-unit-tests" +easy.columns = {"suite": "unit"} +``` + + + +Locally, `hud eval` is unchanged: + +```bash +hud eval tasks.py claude +``` + +Programmatically, the `hud.eval(task)` context manager and `task.run(model)` are replaced by entering the variant and handing the run to an agent: + +```python +from hud.agents import create_agent + +agent = create_agent("claude-sonnet-4-5") +async with fix_tests(target="tests/") as run: + await agent(run) +print(run.reward) +``` + +`create_agent` routes any model (`claude-...`, `gpt-...`, `gemini-...`, `grok-...`) through the HUD gateway and wires the tools for whichever capabilities the environment exposes. + + + +v5 served an MCP server via `env.run(transport=...)`. v6 serves its control channel — use `hud dev` while iterating and `hud deploy` to publish (it builds and publishes in one step). `await env.serve(host, port)` is the in-code equivalent. + + + + +## Converting with an agent + +The conversion is mechanical, so the fastest path is to let your coding agent do it. Add the HUD docs to your agent — they're available as an MCP server at `docs.hud.ai/mcp`, or use the **Copy / Claude / ChatGPT** buttons at the top of any docs page — then point it at this guide and the [Environment reference](/reference/environments) and ask it to adapt your `env.py`. A prompt like: + +> Convert this v5 HUD environment to v6 using the migration guide at docs.hud.ai. Rename scenarios to tasks, replace registered tools with the capability they imply (shell/files → `ssh`, browser → `cdp`, computer-use → `rfb`, custom tools → `mcp`), switch `env("name", ...)` to calling the task, and fix the `hud.tools` imports below. + +Because every old import still resolves (the SDK ships shims) and registered tools are auto-promoted to capabilities at serve time, **your environment keeps running throughout** — convert incrementally and let the `DeprecationWarning`s tell you what's left. + +### Imports to update + +In v6, `hud.tools` is a deprecation shim.

The +canonical reference is [Designing tasks for signal](/v6/advanced/signal). + +### 1. Constant / echo / shape-only grader → reward hacking + +**Trigger:** a grader that returns a constant (`return 1.0`), echoes the answer +back as a pass, runs `echo PASS`, defaults-to-pass on crash, or checks only the +*shape* ("did it return a number?") not the *value* ("did it return 86?"). + +**Tell the user:** This will be reward-hacked. A grader gets optimized against +repeatedly — anything not actively rewarded is ignored, anything accidentally +rewarded is exploited. Grade **substance, not surface form**: credit a correct +answer in a different format, but never credit the shape alone. The cheapest +path that scores *without doing the work* must sit at or below the floor. + +**Cite:** [/v6/advanced/signal](/v6/advanced/signal) ("Resist the cheapest +path"), [Graders](/v6/reference/graders). + +### 2. All-equal rewards → no within-group spread + +**Trigger:** every rollout of a task scores the same (all 0.0 or all 1.0); or +the user judges a task by its *average* reward. + +**Tell the user:** GRPO computes advantage as `reward − group_mean`. If every +rollout in the group is equal, the advantage is zero and **no gradient is +produced** — the task teaches nothing, however good the average looks. The unit +of trainability is *within-group spread*, not the mean. Run a group +(`Taskset(...).run(agent, group=16)`) and confirm a non-degenerate spread. +All-one (saturated) is wasted surface; all-zero at small group sizes may still +be learnable at training scale, but investigate it. + +**Cite:** [/v6/advanced/signal](/v6/advanced/signal) ("Signal lives in +within-group spread"), [Training](/v6/run/training). + +### 3. Public-benchmark substrate → contamination + +**Trigger:** the task is built on a popular public benchmark, a widely-scraped +repo, or any material the model likely saw in pretraining. + +**Tell the user:** If the model saw the material in pretraining, you're +measuring recall, not capability — and the reward can come from *recognizing the +source* instead of solving the problem. Prefer proprietary, self-generated, or +transformed substrate. Public material is fine as *inspiration* (e.g. a public +codebase operated to generate fresh logs), but not handed to the agent verbatim. +Keep real failures and edge cases — they're the signal; don't fabricate +synthetic substrate to look real. + +**Cite:** [/v6/advanced/signal](/v6/advanced/signal) ("Source substrate that +isn't memorized"). + +### 4. Single-shot task → needs multi-step + +**Trigger:** one inference call produces the deliverable; the agent answers in a +single turn with no investigation or tool use. + +**Tell the user:** Single-shot tasks don't give RL enough rollout structure to +learn from. A training task should require **multiple steps** — several +observations, tool calls, or turns. Give the agent a capability to act through +and a problem that requires integrating evidence across more than one +observation (the [ops-diagnostics](/v6/cookbooks/ops-diagnostics) cookbook is a +model example). + +**Cite:** [/v6/advanced/signal](/v6/advanced/signal) ("Make it multi-step"). + +### 5. Comparing only similar top models → need a spanning set + +**Trigger:** the user validates a task only against several similar frontier +models, and concludes it's broken when they don't order cleanly. + +**Tell the user:** Difficulty is only legible against a capability range that +*spans*. Among similarly-capable solvers the ordering is mostly noise — a sound +task can look broken. Evaluate against a deliberate **weak anchor and a strong +anchor**, not a cluster of top performers. Also state the model+reasoning regime +you calibrated against; difficulty has no absolute meaning. + +**Cite:** [/v6/advanced/signal](/v6/advanced/signal) ("Difficulty is relative to +a specific model"). + +### 6. Same-shape taskset → needs diversity + +**Trigger:** every task in the set does the same operation in a different +costume — you can summarize them all with one sentence varying only proper nouns. + +**Tell the user:** A same-shape taskset won't train general capability, +regardless of per-task quality. Diversify across **failure modes targeted, +substrate sources, deliverable shapes, and capabilities exercised**, and spread +the **difficulty distribution** (don't pile up at score 0 or saturation). Size +the set to the training run so it doesn't overfit in the first few steps. + +**Cite:** [/v6/advanced/signal](/v6/advanced/signal) ("Compose a taskset that +isn't all one shape"). + +### 7. Answer leakage in the environment or prompt + +**Trigger:** the substrate or prompt hands over the conclusion — a diff/comment +naming the bug, sentinel grader vocabulary in the prompt, text implying it's an +eval, or author oracle/grading scripts left readable. + +**Tell the user:** An investigation task must not contain its own answer. Remove +root-cause leaks, keep grader-only vocabulary out of the prompt (weave needed +context naturally), don't imply it's a test, and strip author artifacts. + +**Cite:** [/v6/advanced/signal](/v6/advanced/signal) ("Keep the answer out of +the environment"). + +### 8. Prompt ↔ grader misalignment + +**Trigger:** the grader scores content the prompt never asked for, or the prompt +asks for work the grader ignores; or a worse rollout can outscore a better one. + +**Tell the user:** Align them — what the prompt sets up, the grader tests. +Enforce score–quality monotonicity: better substantive work must never score +lower.

Run each task as a group and check that outcomes differ: + +```python +runs = await Taskset(my_task(seed=s) for s in range(5)).run(agent, group=16) +rewards = [r.reward for r in runs] +# All 0.0 (or all 1.0) → no signal. You want a non-degenerate spread. +``` + +- **All-zero** at small group sizes *may* still be learnable at training scale (larger `k` surfaces occasional successes), but it's a red flag worth investigating. +- **All-one (saturated)** produces no spread at any scale — the task is too easy and is wasted training surface. +- **Variance destruction:** a task where the agent does real work but a hard cap, vocabulary gate, or oversized penalty clamps the reward to a narrow band is just as useless as one the agent can't engage with. Keep the reward responsive to the quality of the work. + +## Difficulty is relative to a specific model + +Difficulty has no absolute meaning — every claim of "hard" is anchored to a **specific model, version, and reasoning effort**. A task that spreads nicely for one model saturates for a stronger one. State which model and regime you calibrated against, and re-check when you change it. + +**Compare across a span, not a cluster.** If you only ever check a task against a few similar top-tier models, you can't tell a well-calibrated task from a saturated one. Validate against a **weak anchor and a strong anchor** — a spanning capability range makes the difficulty coordinate legible. + +## Resist the cheapest path + +The single most important grader property: **the highest reward an agent can get without doing the work the task is about must sit at or below the floor.** If there's a shortcut, gradient descent will find it. Common exploits to design against: + +- Hardcoding outputs or substituting a constant for computation. +- Symptom mitigation instead of a root-cause fix (e.g. a `try/except` that swallows a failing test). +- Using the grader's vocabulary without doing the underlying analysis. +- Retrieving an upstream artifact (clone/fetch/install) when the task expects in-workspace work. + + +**Never ship a grader that returns a constant.** `echo PASS`, default-on-crash, or shape-only checks ("did it return *a* number?" instead of "did it return *86*?") give positive reward regardless of behavior — they are pure reward-hacking surface. Grade **substance, not surface form**: credit a correct answer in a different format (thousands separators, casing, whitespace), but never credit the shape alone. + + +## Make it multi-step + +A task where one inference call produces the deliverable doesn't give RL enough rollout structure to learn from. Real training tasks require **multiple steps** — several observations, tool calls, or turns — so the trajectory carries learnable structure. If your task is single-shot, give the agent something to *do*: a [capability](/v6/build/environments) to act through and a problem that requires integrating evidence across more than one observation. + +## Keep the answer out of the environment + +A task that tests investigation must not hand over the conclusion. Watch for **leakage**: + +- **Root-cause leakage** — a diff, PR description, comment, or doc that names the bug/fix the agent is supposed to find. +- **Grader leakage** — sentinel phrases or required vocabulary in the prompt that exist only to satisfy the grader. Weave any needed guidance into natural context instead. +- **Eval-context leakage** — text implying the task is a test, rollout, or judged exercise. (It changes behavior.) +- **Author artifacts** — oracle solutions, grading harnesses, or local paths left where the agent can read them. + +## Align the prompt and the grader + +What the prompt sets up, the grader should test — and vice versa. Two related properties: + +- **Prompt–grader alignment:** don't score for content the prompt never asked for, and don't ask for work the grader ignores. +- **Score–quality monotonicity:** a rollout whose substantive work is *better* must not score *lower*. If a generic memo that did no investigation can outscore a thorough one, the grader is measuring shape, not substance. + +Compose graders so a partial reward is legible (see [`Grade.gather`](/v6/reference/graders)) — subscores let you see which component earned the reward, which is how you catch monotonicity violations. + +## Source substrate that isn't memorized + +If the agent saw your task's material during pretraining, you're measuring recall, not capability. Prefer **proprietary, self-generated, or transformed** substrate over public benchmarks: + +- **Avoid contamination:** popular public benchmarks and widely-scraped repos are overrepresented in pretraining — a model can recognize the source instead of solving the problem. +- **Public as inspiration, not substrate:** a public codebase *operated* to generate fresh logs/traces is fine; the same codebase handed to the agent verbatim is not. +- **Authenticity is the value:** real failures, partial successes, and edge cases carry the signal. Don't sanitize them away, and don't fabricate synthetic substrate to look real. + +## Compose a taskset that isn't all one shape + +A single great task isn't a dataset. A taskset where every task does the same thing in a different costume — same operation, different proper nouns — won't train general capability. + +- **Diversify** across failure modes targeted, substrate sources, deliverable shapes, and capabilities exercised. Diagnostic: if you can summarize every task with one sentence varying only the nouns, it's too same-shape. +- **Spread the difficulty distribution.** Concentrating tasks at score 0 or at saturation wastes training surface; aim for a controlled range against your calibration anchor. +- **Size it** to the training run so it doesn't overfit in the first few steps. + +## Checklist + +The grader's cheapest path scores at or below the floor (no constant/echo/shape-only passes). +A group of rollouts produces non-degenerate reward spread. +Difficulty is calibrated against a named model + reasoning regime, checked across a weak↔strong span. +The task is multi-step and requires integrating evidence. +No root-cause, grader, or eval-context leakage in the environment or prompt. +Prompt and grader are aligned; better work always scores higher. +Substrate isn't a memorized public benchmark. +The taskset is diverse and spans a difficulty distribution. + +## See also + + + + + + + diff --git a/docs/v6/cookbooks/codex-coding.mdx b/docs/v6/cookbooks/codex-coding.mdx new file mode 100644 index 000000000..9156f5595 --- /dev/null +++ b/docs/v6/cookbooks/codex-coding.mdx @@ -0,0 +1,99 @@ +--- +title: "Coding agent" +description: "Run a coding agent against a shell + files environment, graded by tests." +icon: "code" +--- + +A complete, runnable example: an `ssh` environment backed by a `Workspace`, a task that asks the agent to make a failing test pass, and a `BashGrader` that scores by running the test suite. + +## The environment + +The `Workspace` gives the agent a sandboxed shell and files under `/workspace`.

The environment ships as one standardized image that runs on any rollout infra like [Daytona](https://www.daytona.io/), [Modal](https://modal.com/), or [E2B](https://e2b.dev/), and a trainer needs only the rewards and a model API, so feeding rollouts into your own GRPO/PPO loop or a stack like [Tinker](https://thinkingmachines.ai/tinker/), [slime](https://github.com/THUDM/slime), or [Fireworks](https://fireworks.ai/) takes no environment-side glue. + +## The protocol + +HUD is protocol-first.

We built custom tools using their GraphQL API: - -```python -# environments/tools/railway.py -from hud.server import MCPRouter -import httpx -import os - -router = MCPRouter() -RAILWAY_API = "https://backboard.railway.com/graphql/v2" - - -async def _graphql(query: str, variables: dict | None = None) -> dict: - token = os.getenv("RAILWAY_API_TOKEN") - async with httpx.AsyncClient() as client: - resp = await client.post( - RAILWAY_API, - headers={"Authorization": f"Bearer {token}"}, - json={"query": query, "variables": variables} - ) - return resp.json() - - -@router.tool() -async def railway_list_projects() -> dict: - """List all projects with their services.""" - return await _graphql(""" - query { - projects { - edges { node { id name } } - } - } - """) - - -@router.tool() -async def railway_get_deployment_logs(deployment_id: str) -> dict: - """Get logs for a deployment.""" - return await _graphql(""" - query($id: String!) { - deploymentLogs(deploymentId: $id) { - ... on Log { message timestamp severity } - } - } - """, {"id": deployment_id}) -``` - -Then include the router in your environment: - -```python -# environments/railway.py -from hud import Environment -from .tools.railway import router - -railway_env = Environment(name="railway-agent") -railway_env.include_router(router) -``` - -### Defining the Scenario - -The scenario is the contract between orchestrator and subagent: - -```python -@sentry_env.scenario("investigate") -async def investigate_issue( - query: str, # Orchestrator provides this - expected_finding: str | None = None, # Hidden from orchestrator (eval-only) -): - """Investigate errors in Sentry.""" - - prompt = f"""You are a Sentry specialist.

When the orchestrator calls a subagent tool, the inference and tool calls are recorded under the parent trace—no separate URLs to track. - -## The READ-ONLY Constraint - - -We tested and operated this environment directly on our production systems, so all scenarios enforce read-only constraints. We removed mutation tools like `kubectl_exec`, `railway_redeploy`, and Supabase DDL operations. - -Every prompt includes: **"This is a READ-ONLY investigation."** - - -## Sample Output - -Running against a real production issue: - -```bash -python orchestrator.py --model claude-sonnet-4-5 \ - "Failed to delete pod: 429 Too Many Requests. 7451 events, escalating." -``` - -The orchestrator delegates to `investigate_sentry`, `investigate_railway`, and `investigate_supabase`, then correlates findings across services.

Implement Pod Deletion Queue - - Use background queue (Redis, Celery) for pod deletions - - Process deletions with controlled rate (e.g., 100/minute globally) - - Provides visibility into deletion backlog - - 6. Fix Supabase Security Issues - - URGENT: Add RLS policies to 38 tables currently without policies - - Enable leaked password protection - - Reduce OTP expiry to < 1 hour - - Index 52 foreign keys for query performance - - Remove 5 duplicate indexes - - 7. Upgrade ████ Team or Implement Graduated Rate Limits - - ████ team (22 members, free tier) using 15,933 API calls/day - (enterprise-level) - - Either upgrade to paid tier or implement request throttling - - Add monitoring for teams exceeding tier limits - - MEDIUM PRIORITY - Within 1 Week - - 8. Add Monitoring & Alerting - - Track pod deletion success/failure rates - - Monitor K8s API rate limit headers (X-RateLimit-Remaining) - - Alert when deletion failure rate > 5% - - Add dashboards for pod lifecycle metrics - - 9.

Optimize Pod Lifecycle - - Review if pods can be longer-lived (reduce churn) - - Consider pod pooling/reuse for similar tasks - - Use K8s native garbage collection where possible - - Set propagationPolicy=Background for async cleanup - - 11. Fix Supabase Connection Pool - - Switch auth server to percentage-based connection allocation - - Current: 49 waiting connections out of 52 (saturation) - - Monitor connection wait times and adjust pool size - - LOW PRIORITY - Technical Debt - - 12. Update Deprecated Dependencies - - Replace close() with aclose() for Redis connections - - Update Supabase client for new parameter configuration - - Address deprecation warnings in logs - - 13. Add Request Coalescing - - Batch multiple pod deletions into single API calls where possible - - Implement request deduplication for identical operations - -VALIDATION STEPS - - After implementing fixes, validate with: - - 1. Sentry: Monitor ORCHESTRATOR-AC for decreased error frequency (target: 0 - errors) - 2. Kubernetes: Check API server metrics for reduced throttling events - 3.

Action modes* (multi-mode models only) — *In Development* + +> **\* In Development.** This section (and the analogous, undocumented +> `observation_modes` wrapper) is **experimental and not part of the standard +> contract schema**. The going-forward standard is **one action space and one +> observation space per contract** — a model/env that supports several action or +> observation forms is expressed as **separate contracts**, one per form +> (e.g. `xvla_libero.json`, `xvla_widowx.json`, `xvla_calvin.json` instead of a +> single `xvla.json` with `action_modes` + `observation_modes`; `droid_joint_pos.json` +> and `droid_joint_vel.json` instead of a `droid.json` with `action_modes`). The +> original multi-mode specs are preserved under `contracts/experiments/` rather than +> deleted. The matching code (`matching.py`) still implements the wrappers below, so +> they remain documented here for reference until the design settles. + +Single-action models put the action under `features` as `action.`*. + +A model that exposes several action forms (e.g. a native output plus env-paired +reductions) uses an `action_modes` wrapper; each mode owns a nested `features` dict +of split sub-features: + +```json +"action_modes": { + "ee6d_abs": { "native": true, "preferred": true, "comment": "...", + "features": { + "action.arm0.eef_pos": { "role": "action", "state_type": "EE_ABS_POS", + "state_representation": "XYZ", "frame": "base", "order": "0-2", ... }, + "action.arm0.eef_rot": { "state_type": "EE_ABS_ROT", + "state_representation": "ROT6D", "order": "3-8", ... } + } + } +} +``` + +--- + +## 6. Conventions & motivations + +These come from explicit design decisions; follow them for consistency. + +1. **Names follow the producer's own convention.** Env feature leaf-names use the + simulator/robot's native keys (`agentview_image`, `robot0_eef_pos`, `left_arm`); + model leaf-names use the checkpoint's keys (e.g. pi0.5's LeRobot keys `image`, + `image2`). A `role` prefix (`observation.state.*` / `action.*`) keeps keys unique. + *Why:* matching wires producer→consumer; each side should be self-describing in + its own terms, and conversions are the matcher's job. +2. `**normalization` is model-side only.** Envs emit raw values → declare `dtype` + + `stats` (and `limits`) only. *Why:* normalization is part of the model's identity + (baked into its processors), not the environment. +3. **Encode the robot's *real* action.** When a simulator wrapper exposes a different + action space than the physical robot (e.g. ALOHA real = absolute joint positions, + some sims expose EE-delta), spec the real one and note the sim variant in a + `comment`. +4. **Multi-limb side via key + `names` + `order`,** never a token. Bimanual ALOHA: + `left_arm` (`order 0-5`), `left_gripper` (`6`), `right_arm` (`7-12`), + `right_gripper` (`13`). *Why:* keeps `state_type` small and general. +5. **Image layout is explicit (`state_representation`), batch is implicit.** Specs + describe a single sample; the batch dim is always first and never written. +6. **Image `dtype` = what the producer puts on the wire.** Sim bridges typically emit + `uint8` [0,255]; a model contract declares what it ingests (often `float32` + [0,1]). The matcher reconciles dtype + range. *Why:* faithful to each side's I/O. +7. `**frame` is per-feature and EE-only,** and may differ within one pose (OSC: + base-frame translation, eef-frame rotation). *Why:* this is the #1 silent-failure + source; making it explicit per sub-feature catches it. +8. **Gripper is its own space (`GRIPPER`)** — e.g. `GRIPPER_ABS_POS`, disambiguated by + `state_representation` (`BINARY`/`NORM01`/`NORM11`/`REAL`). Keep it out of `JOINT` + so a gripper never shares a `state_type` token with an arm joint (which otherwise + pollutes the action signature used for matching/filtering). The gripper is usually + **absolute even when the arm is delta** — splitting per-feature expresses this + cleanly. *Exception:* a raw multi-joint `qpos` vector that already bundles finger + joints with arm joints stays a single `JOINT_*` feature; use `GRIPPER` only for a + standalone gripper feature. Dexterous multi-DoF hands remain `JOINT`. +9. `**kp`/`kd` on both sides;** `limits` distinct from `stats` (hard bound vs observed + distribution); `chunk_size` top-level on the model. +10. `**decision_variables` defines the schema;** every `robot_type_variables` entry + includes all of its keys (`null` when unused). Empty schema `{}` when the model + has no per-embodiment knobs. + +--- + +## 7. Things to look out for / extra research + +The hardest fields are semantic and rarely stated plainly — derive them from code, +configs, model cards, and papers, not assumptions. Flag anything uncertain `OPEN:`. + +- `**state_representation` (rotation) — the #1 trap.** + - Euler **order** (`EULXYZ` vs `EULZYX`) and intrinsic vs extrinsic. + - Quaternion **order** (`QUATWXYZ` vs `QUATXYZW`) — robosuite uses xyzw; many + libraries use wxyz. + - `AXISANGLE` (rotvec) vs separate axis+angle; `ROT6D` ordering; `SO3` row/col major. + - Composite `POSE`/`TWIST` ordering (translation first, then rotation). +- `**state_type` decomposition.** + - `POS` (translation) vs `POSE` (full 6-DoF) vs `ROT` (orientation only). + - `REF`: delta relative to *what* (previous step vs first state of an action chunk). + - Gripper ref ≠ arm ref (absolute gripper, delta arm). +- `**frame`.** base vs world vs eef vs camera; absolute and delta can use different +frames; OSC splits translation/rotation frames. Verify against the controller. +- **Normalization stats.** Part of model identity; per-dataset; `quantile` (VLAs) vs +`mean_std`/`min_max` (imitation policies). Some base checkpoints ship **no** stats +(identity). Get them from the checkpoint's processor config. +- `**units`.** rad vs deg; **normalized/calibration-dependent** joint values (e.g. +SO-100/SO-101 servos report ~[-100,100] % of calibrated range; zero ≠ URDF zero). +Gripper in meters vs normalized vs joint angle. +- **Gripper sign/range.** open vs close sign, `[0,1]` vs `[-1,1]` vs binary. +- **Cameras.** Which physical view each slot is (ego/agent, wrist L/R, external). +Convention: order by importance — egocentric/agent first, then wrist, external last; +record the mapping in `comment`. On a view-count mismatch the model drops or +zero-pads (`padding: true`). +- **Control rate & chunking.** Native rate, `chunk_size`, how many steps execute +before re-inference; policy quality degrades off the native rate. +- **Special embodiments.** PD-target locomotion (Kp/Kd per joint, `action_scale`, +decimation, default joint pos); mobile base extra DOFs (`BASE_`*, SE(2)/SE(3)); +discrete mode-switch / terminate flags (RT-X) — not yet first-class, note in +`comment`. +- `**robot_class` disambiguation.** Encode arm DoF + gripper DoF (`arm6g1` vs +`arm7g1`); use `bimanual`, `humanoid`, `quadruped`, `mobile_manip`, else +`unclassed`. + +--- + +## 8.

Conventions & motivations + +These come from explicit design decisions; follow them for consistency. + +1. **Names follow the producer's own convention.** Env feature leaf-names use the + simulator/robot's native keys (`agentview_image`, `robot0_eef_pos`, `left_arm`); + model leaf-names use the checkpoint's keys (e.g. pi0.5's LeRobot keys `image`, + `image2`). A `role` prefix (`observation.state.*` / `action.*`) keeps keys unique. + *Why:* matching wires producer→consumer; each side should be self-describing in + its own terms, and conversions are the matcher's job. +2. `**normalization` is model-side only.** Envs emit raw values → declare `dtype` + + `stats` (and `limits`) only. *Why:* normalization is part of the model's identity + (baked into its processors), not the environment. +3. **Encode the robot's *real* action.** When a simulator wrapper exposes a different + action space than the physical robot (e.g. ALOHA real = absolute joint positions, + some sims expose EE-delta), spec the real one and note the sim variant in a + `comment`. +4. **Multi-limb side via key + `names` + `order`,** never a token. Bimanual ALOHA: + `left_arm` (`order 0-5`), `left_gripper` (`6`), `right_arm` (`7-12`), + `right_gripper` (`13`). *Why:* keeps `state_type` small and general. +5. **Image layout is explicit (`state_representation`), batch is implicit.** Specs + describe a single sample; the batch dim is always first and never written. +6. **Image `dtype` = what the producer puts on the wire.** Sim bridges typically emit + `uint8` [0,255]; a model contract declares what it ingests (often `float32` + [0,1]). The matcher reconciles dtype + range. *Why:* faithful to each side's I/O. +7. `**frame` is per-feature and EE-only,** and may differ within one pose (OSC: + base-frame translation, eef-frame rotation). *Why:* this is the #1 silent-failure + source; making it explicit per sub-feature catches it. +8. **Gripper is its own space (`GRIPPER`)** — e.g. `GRIPPER_ABS_POS`, disambiguated by + `state_representation` (`BINARY`/`NORM01`/`NORM11`/`REAL`). Keep it out of `JOINT` + so a gripper never shares a `state_type` token with an arm joint (which otherwise + pollutes the action signature used for matching/filtering). The gripper is usually + **absolute even when the arm is delta** — splitting per-feature expresses this + cleanly. *Exception:* a raw multi-joint `qpos` vector that already bundles finger + joints with arm joints stays a single `JOINT_*` feature; use `GRIPPER` only for a + standalone gripper feature. Dexterous multi-DoF hands remain `JOINT`. +9. `**kp`/`kd` on both sides;** `limits` distinct from `stats` (hard bound vs observed + distribution); `chunk_size` top-level on the model. +10. `**decision_variables` defines the schema;** every `robot_type_variables` entry + includes all of its keys (`null` when unused). Empty schema `{}` when the model + has no per-embodiment knobs. + +--- + +## 7.

Action modes* (multi-mode models only) — *In Development* - -> **\* In Development.** This section (and the analogous, undocumented -> `observation_modes` wrapper) is **experimental and not part of the standard -> contract schema**. The going-forward standard is **one action space and one -> observation space per contract** — a model/env that supports several action or -> observation forms is expressed as **separate contracts**, one per form -> (e.g. `xvla_libero.json`, `xvla_widowx.json`, `xvla_calvin.json` instead of a -> single `xvla.json` with `action_modes` + `observation_modes`; `droid_joint_pos.json` -> and `droid_joint_vel.json` instead of a `droid.json` with `action_modes`). The -> original multi-mode specs are preserved under `contracts/experiments/` rather than -> deleted.

Conventions & motivations - -These come from explicit design decisions; follow them for consistency. - -1. **Names follow the producer's own convention.** Env feature leaf-names use the - simulator/robot's native keys (`agentview_image`, `robot0_eef_pos`, `left_arm`); - model leaf-names use the checkpoint's keys (e.g. pi0.5's LeRobot keys `image`, - `image2`). A `role` prefix (`observation.state.*` / `action.*`) keeps keys unique. - *Why:* matching wires producer→consumer; each side should be self-describing in - its own terms, and conversions are the matcher's job. -2. `**normalization` is model-side only.** Envs emit raw values → declare `dtype` + - `stats` (and `limits`) only. *Why:* normalization is part of the model's identity - (baked into its processors), not the environment. -3. **Encode the robot's *real* action.** When a simulator wrapper exposes a different - action space than the physical robot (e.g. ALOHA real = absolute joint positions, - some sims expose EE-delta), spec the real one and note the sim variant in a - `comment`. -4. **Multi-limb side via key + `names` + `order`,** never a token. Bimanual ALOHA: - `left_arm` (`order 0-5`), `left_gripper` (`6`), `right_arm` (`7-12`), - `right_gripper` (`13`). *Why:* keeps `state_type` small and general. -5. **Image layout is explicit (`state_representation`), batch is implicit.** Specs - describe a single sample; the batch dim is always first and never written. -6. **Image `dtype` = what the producer puts on the wire.** Sim bridges typically emit - `uint8` [0,255]; a model contract declares what it ingests (often `float32` - [0,1]). The matcher reconciles dtype + range. *Why:* faithful to each side's I/O. -7. `**frame` is per-feature and EE-only,** and may differ within one pose (OSC: - base-frame translation, eef-frame rotation). *Why:* this is the #1 silent-failure - source; making it explicit per sub-feature catches it. -8. **Gripper is its own space (`GRIPPER`)** — e.g. `GRIPPER_ABS_POS`, disambiguated by - `state_representation` (`BINARY`/`NORM01`/`NORM11`/`REAL`). Keep it out of `JOINT` - so a gripper never shares a `state_type` token with an arm joint (which otherwise - pollutes the action signature used for matching/filtering). The gripper is usually - **absolute even when the arm is delta** — splitting per-feature expresses this - cleanly. *Exception:* a raw multi-joint `qpos` vector that already bundles finger - joints with arm joints stays a single `JOINT_*` feature; use `GRIPPER` only for a - standalone gripper feature. Dexterous multi-DoF hands remain `JOINT`. -9. `**kp`/`kd` on both sides;** `limits` distinct from `stats` (hard bound vs observed - distribution); `chunk_size` top-level on the model. -10. `**decision_variables` defines the schema;** every `robot_type_variables` entry - includes all of its keys (`null` when unused). Empty schema `{}` when the model - has no per-embodiment knobs. - ---- - -## 7. Things to look out for / extra research - -The hardest fields are semantic and rarely stated plainly — derive them from code, -configs, model cards, and papers, not assumptions. Flag anything uncertain `OPEN:`. - -- `**state_representation` (rotation) — the #1 trap.** - - Euler **order** (`EULXYZ` vs `EULZYX`) and intrinsic vs extrinsic. - - Quaternion **order** (`QUATWXYZ` vs `QUATXYZW`) — robosuite uses xyzw; many - libraries use wxyz. - - `AXISANGLE` (rotvec) vs separate axis+angle; `ROT6D` ordering; `SO3` row/col major. - - Composite `POSE`/`TWIST` ordering (translation first, then rotation). -- `**state_type` decomposition.** - - `POS` (translation) vs `POSE` (full 6-DoF) vs `ROT` (orientation only). - - `REF`: delta relative to *what* (previous step vs first state of an action chunk). - - Gripper ref ≠ arm ref (absolute gripper, delta arm). -- `**frame`.** base vs world vs eef vs camera; absolute and delta can use different -frames; OSC splits translation/rotation frames. Verify against the controller. -- **Normalization stats.** Part of model identity; per-dataset; `quantile` (VLAs) vs -`mean_std`/`min_max` (imitation policies). Some base checkpoints ship **no** stats -(identity). Get them from the checkpoint's processor config. -- `**units`.** rad vs deg; **normalized/calibration-dependent** joint values (e.g. -SO-100/SO-101 servos report ~[-100,100] % of calibrated range; zero ≠ URDF zero). -Gripper in meters vs normalized vs joint angle. -- **Gripper sign/range.** open vs close sign, `[0,1]` vs `[-1,1]` vs binary. -- **Cameras.** Which physical view each slot is (ego/agent, wrist L/R, external). -Convention: order by importance — egocentric/agent first, then wrist, external last; -record the mapping in `comment`. On a view-count mismatch the model drops or -zero-pads (`padding: true`). -- **Control rate & chunking.** Native rate, `chunk_size`, how many steps execute -before re-inference; policy quality degrades off the native rate. -- **Special embodiments.** PD-target locomotion (Kp/Kd per joint, `action_scale`, -decimation, default joint pos); mobile base extra DOFs (`BASE_`*, SE(2)/SE(3)); -discrete mode-switch / terminate flags (RT-X) — not yet first-class, note in -`comment`. -- `**robot_class` disambiguation.** Encode arm DoF + gripper DoF (`arm6g1` vs -`arm7g1`); use `bimanual`, `humanoid`, `quadruped`, `mobile_manip`, else -`unclassed`. - ---- - -## 8.

Conventions & motivations - -These come from explicit design decisions; follow them for consistency. - -1. **Names follow the producer's own convention.** Env feature leaf-names use the - simulator/robot's native keys (`agentview_image`, `robot0_eef_pos`, `left_arm`); - model leaf-names use the checkpoint's keys (e.g. pi0.5's LeRobot keys `image`, - `image2`). A `role` prefix (`observation.state.*` / `action.*`) keeps keys unique. - *Why:* matching wires producer→consumer; each side should be self-describing in - its own terms, and conversions are the matcher's job. -2. `**normalization` is model-side only.** Envs emit raw values → declare `dtype` + - `stats` (and `limits`) only. *Why:* normalization is part of the model's identity - (baked into its processors), not the environment. -3. **Encode the robot's *real* action.** When a simulator wrapper exposes a different - action space than the physical robot (e.g. ALOHA real = absolute joint positions, - some sims expose EE-delta), spec the real one and note the sim variant in a - `comment`. -4. **Multi-limb side via key + `names` + `order`,** never a token. Bimanual ALOHA: - `left_arm` (`order 0-5`), `left_gripper` (`6`), `right_arm` (`7-12`), - `right_gripper` (`13`). *Why:* keeps `state_type` small and general. -5. **Image layout is explicit (`state_representation`), batch is implicit.** Specs - describe a single sample; the batch dim is always first and never written. -6. **Image `dtype` = what the producer puts on the wire.** Sim bridges typically emit - `uint8` [0,255]; a model contract declares what it ingests (often `float32` - [0,1]). The matcher reconciles dtype + range. *Why:* faithful to each side's I/O. -7. `**frame` is per-feature and EE-only,** and may differ within one pose (OSC: - base-frame translation, eef-frame rotation). *Why:* this is the #1 silent-failure - source; making it explicit per sub-feature catches it. -8. **Gripper is its own space (`GRIPPER`)** — e.g. `GRIPPER_ABS_POS`, disambiguated by - `state_representation` (`BINARY`/`NORM01`/`NORM11`/`REAL`). Keep it out of `JOINT` - so a gripper never shares a `state_type` token with an arm joint (which otherwise - pollutes the action signature used for matching/filtering). The gripper is usually - **absolute even when the arm is delta** — splitting per-feature expresses this - cleanly. *Exception:* a raw multi-joint `qpos` vector that already bundles finger - joints with arm joints stays a single `JOINT_*` feature; use `GRIPPER` only for a - standalone gripper feature. Dexterous multi-DoF hands remain `JOINT`. -9. `**kp`/`kd` on both sides;** `limits` distinct from `stats` (hard bound vs observed - distribution); `chunk_size` top-level on the model. - ---- - -## 7.

drop the redundant hud_api_version setting and keep hud_api_url a bare origin. - Tasksets: map the canonical {env, scenario} export pair straight onto Task (the control plane now strips legacy v5 env qualifiers). - Manifest: publish each task's args JSON Schema for platform-side validation, failing loudly when an arg annotation can't be schematized. - deploy: resolve the environment name from the Environment(...) declaration as the single identity (deploy-by-name get-or-rebuild); drop the --name flag and the interactive 409 name-conflict prompt. - cancel: adapt to the control plane's two-phase cancel contract (accepted / noop). - Update CLI source parsing, job/build-log helpers, docs, and tests. --- docs/v6/advanced/harbor-convert.mdx | 7 +- docs/v6/advanced/patterns.mdx | 3 +- docs/v6/reference/cli.mdx | 5 +- docs/v6/run/deploy.mdx | 3 +- hud/cli/cancel.py | 23 ++-- hud/cli/deploy.py | 169 ++++++++++--------------- hud/cli/tests/test_deploy.py | 83 ++++++++++++ hud/cli/utils/build_logs.py | 4 +- hud/cli/utils/jobs.py | 6 +- hud/cli/utils/source.py | 66 +++++++--- hud/cli/utils/tests/test_registry.py | 2 +- hud/cli/utils/tests/test_source.py | 45 +++++-- hud/environment/env.py | 32 ++++- hud/environment/tests/test_manifest.py | 88 +++++++++++++ hud/eval/sync.py | 31 ++--- hud/eval/tests/test_sync.py | 40 +++--- hud/settings.py | 2 +- hud/utils/platform.py | 13 +- hud/utils/tests/test_platform.py | 23 +++- 19 files changed, 440 insertions(+), 205 deletions(-) create mode 100644 hud/environment/tests/test_manifest.py diff --git a/docs/v6/advanced/harbor-convert.mdx b/docs/v6/advanced/harbor-convert.mdx index 29c7efbcd..4cfe05636 100644 --- a/docs/v6/advanced/harbor-convert.mdx +++ b/docs/v6/advanced/harbor-convert.mdx @@ -20,9 +20,8 @@ run it from a checkout. ## Load Harbor tasks `load(path)` parses a Harbor task dir (or a dataset of them) into a `Taskset` -directly — one row per task dir (`id` = the dir name, `task.toml` metadata as -columns), sharing one declarative `Environment` per distinct `environment/` -build context: +directly — one row per task dir (`id` = the dir name), sharing one declarative +`Environment` per distinct `environment/` build context: ```python from integrations.harbor import detect, load @@ -31,7 +30,7 @@ assert detect("./terminal-bench") taskset = load("./terminal-bench") for task in taskset: - print(task.env, task.id, task.columns) + print(task.env, task.id) ``` Like every task row, the result carries no placement.

No hosting branch; placement is dispatched once in Taskset.run (Provider -> rollout, HUDRuntime -> submit). rollout.py is gone (merged into run.py), which also removes the module/function name clash. - Agents serialize themselves for hosting: ToolAgent.hosted_spec() emits {type, config} with the full AgentConfig (every knob preserved) minus the live model_client, gateway-owned api_key/base_url, and non-serializable hosted_tools; AgentType.of() is the reverse-lookup.

The `robot` capability is a **schema-driven observation/action loop over WebSocket**.

Inputs are `Run`s (sent inline) or `trace_id` strings (resolved from trajectories the platform already holds) — mix freely. + + +Built-in losses (`importance_sampling`, `ppo`, `cispo`, `dro`, `cross_entropy`) run server-side and need no local ML deps. List the set a model supports with `await trainer.available_losses()`. + + +## Custom losses + +To author the loss yourself — e.g. GLM-style double-sided importance sampling — use `forward_backward_custom`.
