Profile names are validated as conservative slugs and are the only profile input accepted from configuration. + +### Why persistent contexts + +Playwright `storageState` captures cookies and selected web storage, but it is not a complete browser profile. Persistent contexts also retain IndexedDB, service workers, cache-backed authentication data, and browser settings. They therefore give the best chance that a headed login remains valid when reopened headlessly. + +Persistent profiles are not portable sessions. A site can still invalidate a session because the IP address, browser build, client certificate, device attestation, passkey, or risk score changed. Setup and runtime must use the same browser executable and should run on the same host. + +## Operator workflow + +### Create or refresh a profile + +```bash +vp run --filter @t3tools/discord-bot browser-profile setup github-default \ + --url https://github.com/login \ + --verify-url https://github.com/settings/profile \ + --expect-url 'https://github.com/settings/**' +``` + +The command: + +1. Acquires the profile lock. +2. Starts a headed persistent context with the profile's `user-data` directory. +3. Navigates to the setup URL and waits for the operator to finish login. +4. On Enter or browser close, navigates to the optional verification URL. +5. Checks the expected URL pattern, records non-secret metadata, and closes cleanly. + +The command must not infer success merely because cookies exist. Without an explicit verification rule it records the profile as unverified and warns the operator. + +### Verify without changing the profile + +```bash +vp run --filter @t3tools/discord-bot browser-profile verify github-default +``` + +Verification opens the persistent context headlessly, visits the configured verification URL, and checks the expected URL pattern. A failed check reports that headed setup must be rerun; it does not delete the profile. + +### Run the bot + +```bash +T3_DISCORD_BROWSER_ENABLED=true \ +T3_DISCORD_BROWSER_PROFILE=github-default \ +T3_DISCORD_BROWSER_EXECUTABLE_PATH=/usr/bin/google-chrome \ +vp run --filter @t3tools/discord-bot start +``` + +The initial implementation uses one configured default profile. Named per-project or per-channel profile selection can be added later, but the selected name must always come from trusted bot configuration rather than agent text. + +## Host lifecycle + +The browser host starts after the bot has established its T3 WebSocket session: + +1. Validate the configured profile and browser executable. +2. Acquire an exclusive profile lock. +3. Launch one headless persistent context. +4. Register a stable host client ID and supported operations with `previewAutomationConnect`. +5. Process streamed requests and answer through `previewAutomationRespond`. +6. On disconnect, cancel outstanding work, close the context, release the lock, and reconnect with the bot session. + +Tabs are keyed by the contract `PreviewTabId`. The host keeps an in-memory map from tab ID to Playwright page. `open` creates or reuses a page, and subsequent operations use broker tab affinity. Browser state persists across host restarts, while open tab identity does not. The host retains at most four pages per thread and twelve pages across the process, closing least-recently-used pages when either limit is exceeded. Pages with in-flight operations and the active recording page are protected from eviction; temporary overflow is reconciled when an operation completes. + +The host advertises only operations it implements. The first slice supports status, open, navigate, snapshot, click, type, press, scroll, evaluate, and wait-for. Resize and recording remain desktop-only until they have host-neutral semantics. + +## Routing and profile selection + +The current broker prefers a focused compatible host and otherwise chooses an available host. That is sufficient when the bot is the only connected host. It is not enough for deterministic multi-host deployments because focus is a UI concept, not an execution policy. + +A later contract revision should add host capabilities such as `kind: desktop | bot | worker` and an optional trusted profile label, then let invocation context express a host preference. Until then: + +- The bot registers only for its own server environment. +- Operators should avoid connecting a desktop automation host to the same unattended bot environment when deterministic routing matters. +- The bot never exposes raw profile paths or accepts a profile name from an automation request. + +## Concurrency and isolation + +Only one browser process may use a persistent profile directory at a time. The host and profile CLI use the same exclusive lock. A lock records PID and start time for diagnostics, but existence alone is not treated as proof that the owner is alive. Stale-lock recovery must verify process liveness before removal. + +The first implementation protects pages with in-flight operations and caps retained tabs. Later worker isolation can place each profile in a separate child process or microVM while retaining the same broker protocol. + +For multiple identities, create multiple named profiles. Do not log several identities into one browser profile: cookies, account choosers, and cross-origin storage make selection ambiguous and increase accidental privilege crossover. + +## Security policy + +- Treat profile directories as long-lived credentials and restrict filesystem permissions. +- Run the browser and bot as an unprivileged dedicated user. +- Configure an origin allowlist per profile before enabling production automation. +- Reject `file:`, `data:`, browser-internal, and other non-HTTP(S) navigation. +- Redact URL query strings and fragments from logs by default. +- Never include cookies, storage values, page HTML, or evaluated secrets in logs. +- Bound evaluation output, snapshot size, operation time, active pages, and browser memory. +- Capture diagnostic screenshots only when explicitly enabled; screenshots can contain secrets. +- Keep Discord authorization and project authorization unchanged. Browser access adds capability and must not broaden who can trigger bot turns. + +## Failure behavior + +| Condition | Behavior | +| ------------------------ | ------------------------------------------------------------------------------------ | +| Profile is missing | Host does not register; startup reports the setup command. | +| Profile lock is held | Host does not start a second browser; reports lock owner diagnostics. | +| Login verification fails | Request returns a stable session-expired error and points operators to headed setup. | +| Browser crashes | In-flight requests fail, context closes, and the host restarts with bounded backoff. | +| T3 connection drops | Browser closes, lock releases, and host registration follows T3 reconnection. | +| Operation times out | The operation is cancelled without destroying unrelated tabs. | +| Result exceeds limits | The host returns the existing result-too-large error envelope. | + +The first contract may encode profile-specific failures as `PreviewAutomationExecutionError` with a safe operator-facing message. A dedicated `PreviewAutomationProfileUnavailableError` can be added once both server and clients need structured recovery UI. + +## Delivery plan + +### Phase 1: persistent profile and core host + +- Add Playwright persistent-context profile setup, verify, list, and clear commands. +- Add bot configuration for enablement, default profile, executable path, limits, and optional verification. +- Register a bot automation host on the existing WebSocket session. +- Implement the core navigation and interaction operations. +- Add tests for profile validation, metadata, locking, URL policy, operation dispatch, and reconnect cleanup. +- Document deployment prerequisites and the headed-to-headless workflow. + +### Phase 2: deterministic routing and policy + +- Extend host metadata with host kind and profile capability labels. +- Add trusted per-project or per-channel profile selection. +- Add origin allowlists and policy-denial error types to shared contracts. +- Add operator-visible host/profile health without exposing secrets. + +### Phase 3: isolation and parity + +- Move browsers into supervised worker processes or microVMs. +- Add resource quotas and crash-loop protection. +- Define host-neutral resize, screenshot artifact, and recording behavior. +- Add encrypted profile backup/restore only if an operational requirement justifies the risk. + +## Alternatives considered + +### Export only `storageState` + +This is easy to inspect and copy but omits browser-managed state used by many modern login flows. It remains useful for disposable test accounts, not as the primary operator workflow. + +### Keep a headed desktop client connected + +This already works through the broker but is operationally fragile for an unattended Discord bot. Desktop sleep, UI lifecycle, and focus also make routing unpredictable. + +### Remote browser service first + +A remote Playwright/CDP service improves isolation and scaling, but introduces credential transport, another availability dependency, and more deployment work. The in-process host establishes the protocol and profile model first; it can later move behind the same interface. + +## Acceptance criteria for the first implementation + +- An operator can log into a site in a headed browser and close it. +- A separate headless verification process reuses the same authenticated profile. +- The running Discord bot registers as a preview automation host and handles core `preview_*` calls. +- Concurrent processes cannot open the same profile. +- Missing, locked, and expired profiles produce actionable errors without leaking credentials. +- Bot shutdown or WebSocket disconnect closes the browser and releases its lock. diff --git a/docs/examples/project-aliases.yaml b/docs/examples/project-aliases.yaml new file mode 100644 index 00000000000..2a3d0741e5a --- /dev/null +++ b/docs/examples/project-aliases.yaml @@ -0,0 +1,15 @@ +# Discord bot project shortName → workspace root mapping. +# Loaded by the bot only (not the T3 server): +# +# export T3_PROJECT_ALIASES_PATH=~/.t3/discord-bot/project-aliases.yaml +# pnpm --filter @t3tools/discord-bot start +# +# Channel topics use: t3- (e.g. t3-example-project) + +example-project: ~/projects/example-project +# t3-code: ~/pj/t3code + +# Structured form is also supported: +# aliases: +# example-project: +# workspaceRoot: ~/projects/example-project diff --git a/docs/integrations/discord-bot.md b/docs/integrations/discord-bot.md new file mode 100644 index 00000000000..032a2802656 --- /dev/null +++ b/docs/integrations/discord-bot.md @@ -0,0 +1,248 @@ +# T3 Discord Bot + +Headless Effect + [dfx](https://github.com/tim-smart/dfx) client that bridges Discord project channels to T3 Code threads (with optional git worktrees). + +## Prerequisites + +1.

On-demand MCP fetch of arbitrary Discord messages is not implemented yet; only the message you reply to is included automatically. + +Every turn, including continuations, also tells the agent that it is responding as the Discord bot +to the same thread. The prompt identifies the current requester by Discord user ID, username, +and display name (server nickname first, then global display name), so references such as “you” and +participant attribution remain clear even after a long conversation or context compaction. + +## Discord message streaming + +During a turn the bot: + +1. **In progress:** edits its latest message while it remains the channel tip (opens a new tip if someone posts after it, or when text exceeds 2000 characters). Every 10 seconds, the same tracked tip cycles `_Working.._`, `_Working..._`, and `_Working...._` as a liveness heartbeat; when the current turn has tool activity it also shows a collapsed count (e.g. `_Working.. · 3 tool calls_`) — not individual tool rows. It never creates heartbeat messages. Local markdown image paths are hidden during the stream. +2. **On completion:** + - Posts the **final answer as normal Discord message content** (split across multiple messages if over 2000 characters) + - Archives the in-progress stream as an attached `stream-history.md` on the **same createMessage** as the last chunk when it has intermediate progress beyond the final answer (skipped when the tip body is empty or equals the final message; Discord cannot add attachments via edit) + - Deletes **all** live stream messages (including displaced tips) so only the final answer stays in the channel +3. **Images:** always uploaded on `createMessage` with multipart files (never via `updateMessage`): + - T3 chat image attachments (`message.attachments`) via `assets.createUrl` + - Local markdown embeds such as `![alt](attachment:/var/lib/t3/.codex/generated_images/…png)` (scheme stripped) via disk or assets, then real Discord file attachments +4. **Linked local files:** markdown links to local files such as `[table.csv](/tmp/table.csv)` are stripped from the final text and uploaded as real Discord attachments on the final `createMessage` + +### Architecture: client-aligned state, Discord-only projection + +Other T3 clients (web/mobile) keep a live `OrchestrationThread` via +`client-runtime` `EnvironmentThreadState` and **render** it.

The bot only owns _how_ that state is mirrored onto Discord’s message API. + +### Delivery reliability + +The T3 web client and Discord are different _presentation_ paths. The client paints thread state; Discord projects it through ResponseBridge. + +To keep Discord responsive when the orchestration WS stream stalls or Discord REST is slow: + +1. **Coalescing delivery queue** — WS events only publish the latest snapshot. A single worker serializes Discord I/O so a hung `createMessage` cannot block the subscription fiber from receiving later assistant bubbles. Each snapshot applies **stream tip / finalize first**, then title/pin/tasks — mid-turn thread renames and PR lookups must not starve live `_Working.._` tip edits. Live **Tasks** messages are bot-owned and do **not** freeze/reopen the stream tip (only human replies do). Discord **system** messages (channel renames, pins) also do not displace the tip. New threads start Working+bridge **before** the info pin so the agent is not racing an empty tip. Secondary work is time-capped; if `processThreadSnapshot` still times out, the bridge **auto-recovers** (backoff → HTTP reseed → retry) instead of staying stuck until the next WS event. + 1b. **Finalize accept-without-ack** — finals are create-based (not tip edits). On retry, the bridge scans recent bot messages for already-posted final chunks and **adopts** those ids instead of creating duplicates; durable `lastFinalizedAssistantId` is written as soon as the first final chunk lands. +2. **HTTP reconcile (every ~12s)** while Working tips are open, a turn is running, or a Discord-originated turn has not finalized yet — re-fetches `/api/orchestration/threads/:id` and re-applies the snapshot so stuck `_Working.._` tips still resolve to the final answer. +3. **Finalize timeouts** — Discord create/fallback paths for final posts are bounded (~45s) with a text-only fallback so a stuck multipart upload cannot pin the bridge forever. +4. **Boot/reconnect catch-up** — links with open stream tip ids are rehydrated and force-finalize completed turns that finished while the bot was offline. +5. **Mid-turn restart** — in-progress `_Working.._` tips are **not** deleted when the bridge fiber stops during a running turn; rehydrate resumes/edits them (or recreates if Discord already deleted the message). Empty progress still seeds a Working tip so Discord never goes dark while T3 is busy. +6. **Delivery epoch FSM** (`DiscordDelivery.ts`) — each new user Working ack starts a monotonic **epoch** with phases `awaiting → streaming → finalized`. After `finalized`, the **same** assistant is a hard no-op (no final+Working mess), but a **later** assistant after `lastFinalizedAssistantId` (or same-id text growth past `lastFinalizedText`) reopens stream/finalize. **Settle grace** requires two idle snapshots before finalize so multi-step status lines cannot lock the epoch. Assistant selection drops assistants at/before `lastFinalizedAssistantId` in message order — even while `turnInProgress`. +7. **New-thread Working ack + stream timeouts** — new Discord threads post `_Working.._` before the bridge starts (same as continue). Stream tip Discord I/O is time-capped so a hung REST call cannot freeze the delivery queue while T3 keeps advancing. +8. **Subscription auto-retry** — `subscribeThread` no longer dies on a single WS failure; the bridge resubscribes with exponential backoff and HTTP-seeds missed snapshots so deploy restarts / transient drops do not leave Discord on permanent `_Working.._`. +9. **Dual delivery cursor** — `lastThreadSnapshotSequence` advances when T3 state is observed (fast WS resume via `afterSequence`); `lastDeliveredSequence` advances only after Discord delivery succeeds. When delivery lags orchestration, HTTP reconcile and boot rehydrate keep catching up even if stream tips look clean. +10. **Storage / memory efficiency** — link markers stay O(1) (sequences, tip ids, last finalized). A **trimmed warm cache** (`$dataDir/thread-cache/.json`) stores the reduced tip (messages after last finalize minus buffer of 2) + `snapshotSequence`, like web/desktop thread cache. Resume prefers warm base + `afterSequence` (delta catch-up) over full HTTP tip; HTTP is fallback when warm is missing. + +Auth: prefer `T3_BEARER_TOKEN` (long-lived) or `T3_BOOTSTRAP_CREDENTIAL` with `deviceType: bot`. Scopes need `orchestration:read` and `orchestration:operate`. + +## Usage + +Prefer **`/t3`** slash commands (shown first on the channel info pin). `@bot` mentions remain a full fallback. + +| Action | Result | +| ------------------------------------------------- | ------------------------------------------------------------------------------------------------ | +| `/t3 ask prompt:fix the flaky test` | Creates a Discord thread + T3 thread with a new worktree off `main` | +| `/t3 ask prompt:also check CI` in a linked thread | Continues the same T3 thread | +| `/t3 thread-talk action:on` in a linked thread | Lets human messages start turns without a mention until `thread-talk` off | +| `/t3 thread-talk action:status` | Reports whether mention-free thread-talk is enabled | +| `/t3 link ref:` | Pick up an existing T3 thread: create Discord thread if needed, or jump to it | +| `@bot` + **image attachment(s)** | Downloads Discord images and sends them as T3 chat image attachments (max 8) | +| Slash options / mention flags | `model` `provider` `base` `local` `plan` · or `--model` `--provider` `--base` `--local` `--plan` | + +### Native slash commands (preferred; `@bot` still works) + +Guild-scoped `/t3` commands (fast to register for a single-server bot).
