chore: add graphify knowledge graph for agent context - #9
Conversation
Wires the graphify knowledge graph into Claude Code so agents query the graph before grepping raw files, and commits the semantic extraction cache so the graph can be rebuilt without re-paying for LLM extraction. - CLAUDE.md: graphify usage rules for agents - .claude/settings.json: PreToolUse hooks. graphify is resolved from PATH rather than the absolute home path graphify writes by default, which would only work on one machine - .graphifyignore: scan scope. Excludes images, build output and virtualenvs from extraction - .gitignore: ignore generated artifacts but track graphify-out/cache/semantic, the expensive LLM output Co-Authored-By: Claude Opus 5 (1M context) <noreply@anthropic.com>
The PreToolUse hooks ship in project-scope settings, so they run for every collaborator. Without this guard anyone who has not installed graphify gets a command-not-found on essentially every Bash, Grep, Read and Glob call. Exit 127 does not block the tool (only exit 2 does), so the cost was noise rather than breakage, but it degrades the agent's signal for the whole team. Raised by unblocked and claude on causematch/cm2#2670.
📝 WalkthroughSummary
Architectural concerns and downstream impacts
WalkthroughThe change integrates Graphify into Claude tool-use hooks and project guidance. It defines scan and Git exclusion rules, preserves semantic cache contents, and adds semantic graph records for project documentation and proxy architecture. ChangesGraphify integration
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to This PR adds repository graph metadata and default agent hooks, but the current cache can misrepresent HTTP data flow as code calls, while fresh checkouts without the required CLI can produce repeated hook errors and unclear setup failures. Correct the cache relationships and make the hooks/setup path safe before merging. Sequence Diagram(s)sequenceDiagram

Claude Code hooks command hook exit code missing executable behavior non-zero blocks tool use
💡 Result:
In Claude Code, hook exit codes determine whether an action is blocked, permitted, or flagged as an error [1][2]. Understanding how these codes interact with stdout/stderr and tool execution is critical to avoid unintended behavior, such as policy enforcement hooks failing silently [3][4]. Exit Code Behavior - Exit 0: Indicates success [2]. Claude Code parses stdout for JSON output to make fine-grained decisions (e.g., allow, deny, or escalate) [1][5]. For most events, this is the recommended approach for structured control [6][7]. - Exit 2: Signals a blocking error [1][5]. Claude Code ignores any JSON in stdout and feeds the content of stderr back to Claude as an error message or context [1][7]. While this is the official method for blocking, its effectiveness depends on the event type [6][2]. - Other non-zero exit codes (e.g., 1, 3-255): Treated as non-blocking hook execution errors [3][2]. The action proceeds, and a hook error notice is displayed in the transcript (often visible only in verbose mode) [6][3][7]. Critical Nuance and Potential Pitfalls - Silent Bypass Trap: Developers often use exit 1 (the conventional Unix error code) to block actions, but Claude Code treats it as non-blocking [3][2]. Consequently, an enforcement hook that relies on exit 1 will silently fail, allowing the action to proceed [3][4]. - The Edit/Write Tool Caveat: Some reports indicate that for certain tool types, such as Edit and Write, exit 2 may be interpreted as a hook crash rather than a deliberate denial, leading to the operation falling through [4]. Using exit 0 with JSON structured control is generally considered more robust across all tool types [4][7]. - JSON vs. Exit Codes: Claude Code typically ignores JSON output when a hook exits with 2 [6][7]. To ensure your hook's instructions are followed, choose one approach: either exit 2 to block with a simple error message or exit 0 to provide a structured JSON decision [1][6]. Recommendation: For reliable policy enforcement, explicitly use exit 2 for simple blocking, or preferably, use exit 0 with a JSON object containing the appropriate permission decision fields (e.g., hookSpecificOutput.permissionDecision: "deny") [8][4][7]. Avoid exit 1 or other non-zero codes for enforcement [3][2].

Graphify CLI "hook-guard" "graphify extract"
💡 Result:
In the Graphify CLI tool, hook-guard and extract are distinct, functional components used for repository indexing and AI assistant integration [1][2][3]. hook-guard The hook-guard command is an internal CLI subcommand used by Graphify's integration with AI coding assistants (such as Claude Code and Gemini CLI) [1][2][4]. It implements a PreToolUse hook that acts as a nudge mechanism [1][2]. When an AI assistant attempts to read source files or perform searches, the hook-guard checks for the presence of a local knowledge graph [5][4]. If the graph exists, it injects additional context to prompt the assistant to query the graph before accessing raw files [2][4]. This ensures the assistant relies on the processed knowledge graph rather than raw file reads when possible [2][4]. It was designed to provide a shell-agnostic, reliable way to interface with different AI assistant platforms [1]. extract The extract command is the core functionality used to build or update the knowledge graph [3]. It performs the actual parsing and semantic extraction of your codebase, documentation, and configuration files [3][6]. Unlike higher-level commands like /graphify (which typically orchestrates the full build process), extract provides granular control over the indexing process [7][3]. Common flags include: --backend: Specifies the LLM provider (e.g., gemini, claude, ollama) for semantic extraction [3]. --code-only: Performs local AST parsing only, skipping docs and PDFs to avoid using an API key [3]. --no-cluster: Performs raw extraction without the subsequent clustering phase [3]. --timing: Outputs wall-clock performance metrics for the different stages [3]. --mode deep: Enables more aggressive semantic extraction for richer graph edges [7][3]. In short, hook-guard handles the runtime interaction between the assistant and the graph, while extract handles the static analysis and generation of the graph itself [1][2][3].

site:code.claude.com/docs/en/hooks Claude Code command hooks non-zero exit code 127 PreToolUse
💡 Result:
In Claude Code, a non-zero exit code of 127 from a command hook—including those defined for the PreToolUse event—indicates that the specified command script could not be executed because it was not found or could not be run [1]. When a hook script fails to start (e.g., due to a missing file, incorrect path in settings.json, or lack of execute permissions), the shell returns exit code 127 (command not found) [1]. Claude Code treats this as a non-blocking error, meaning the action (the tool call) will generally proceed despite the failure of the hook [1]. To resolve this issue: 1. Verify the file path specified in your settings.json matches the actual location of the script. 2. Ensure the script is executable by running chmod +x <path_to_script> on the hook file [1]. 3. Check that the script has the correct execute permissions and that the interpreter path (if using a shebang) is correct. 4. If you intended for the hook to block the action, remember that exit code 127 is non-blocking; for blocking, you must use exit code 2 [1][2].

site:github.com/Graphify-Labs/graphify "graphify extract ." CLI
💡 Result:
The graphify extract command is a core CLI subcommand in the graphifyy package used to perform headless extraction of codebases, documentation, PDFs, and images into a graph format [1][2]. Key details regarding this command include: Functionality The command detects file types, extracts code via local AST (Abstract Syntax Tree) analysis, and processes documentation, PDFs, and images using LLM-based semantic extraction [2]. It outputs a graph.json file and an accompanying.graphify_analysis.json file [2]. Key Flags and Options --code-only: Indexes only code files using local AST (offline, no API key required) and skips all docs, papers, and images [1][3]. This is ideal for privacy-sensitive or cost-constrained environments [4]. --backend: Specifies the LLM backend (e.g., gemini, claude, openai, deepseek, ollama, bedrock, or claude-cli) [1]. --mode deep: Enables richer semantic extraction using an extended system prompt [1]. --no-cluster: Performs raw extraction only, skipping the community detection/clustering phase [1][2]. --timing: Prints wall-clock timings for each stage of the extraction to stderr [1]. --force: Overwrites existing graph.json files even if the new graph contains fewer nodes [1]. --global: Registers the extraction into a cross-project global graph [1]. Usage Considerations API Key Requirement: An API key is required when the corpus contains non-code files (docs, PDFs, images) unless the --code-only flag is used [3][4]. CI/Headless Usage: The command is designed for headless operation in CI/CD pipelines and does not require an IDE [1][2]. Installation: The official CLI is provided by the graphifyy (note the double-y) package on PyPI, installed via pip or uv (e.g., uv tool install graphifyy) [5]. Note: The command graphify extract is a terminal CLI command. It should not be confused with commands prefixed with a forward slash (e.g., /graphify extract), which are intended to be executed within AI coding assistants as skill commands [6][7].

Use shares_data_with for local HTTP links.
The cm_proxy ↔ mitmproxy and mitmproxy ↔ local_server edges represent HTTP data transfer, not code invocation. Regenerate these edges with shares_data_with, then run the Graphify caller query to ensure it excludes these links.

mitmproxy and local_server, currently use calls but represent HTTP data
transfer. Regenerate both edges with the shares_data_with relation, then rerun
the Graphify caller query and verify these links are excluded.

Adds a queryable knowledge graph of this repo so coding agents can ask
structural questions instead of grepping their way to an answer.
Part of a set across 8 repos. cm2 is the pilot and carries the full rationale:
causematch/cm2#2670 — please read that one for the design decisions. This
description covers what is specific to
cm-proxy.What is committed
Only the semantic cache: 22 JSON files under
graphify-out/cache/semantic/, plus config.The graph itself is gitignored and rebuilt locally — code extraction is
tree-sitter AST, deterministic and free. The cache is the one artifact that is
expensive and not reproducible without an LLM, so committing it means anyone can
rebuild the full graph with no API key and no token spend.
Graph size here: 111 nodes / 181 edges.
The
.gitignoreblock has to readgraphify-out/*rather thangraphify-out/— git does not descend into an ignored directory, so a baredirectory ignore makes the
!graphify-out/cache/semantic/negation unreachableand the cache silently untracked.
To use it after merging
graphify update .after code changes keeps it current — AST only, no API cost.Heads-up on the hook
.claude/settings.jsonadds a PreToolUse hook firinggraphify hook-guardonevery
Bash|Grep|Read|Glob, which is what makes the graph the default ratherthan a thing you have to remember to use.
It does mean anyone with this repo checked out and no
graphifyon PATH getsa failing hook command on every tool call. Worth deciding as a team whether
that belongs in committed settings or in each person's local settings — same
question as on cm2#2670, and it should get the same answer everywhere.
The command resolves from PATH deliberately; graphify's installer writes an
absolute
/Users/<name>/.local/bin/graphify, which would break for everyoneelse. Rewritten here.
Risk
Additive only. No source changes, no build or runtime impact. Reverting is
deleting the directory and the config files. Committed cache files were scanned
for credential and key patterns before pushing: no hits.
