code-context-graph AGENTS.md

Repository instructions for a local code-analysis tool that parses source code and builds a knowledge graph, a structured map of relationships in a codebase.

In plain words
What is it for?
Use them when exploring a codebase, finding related code, tracing data or execution paths, checking what a change affects, or maintaining the tool's MCP server and webhooks.
Why use it?
They tell coding agents how to use the tool's code search, dependency tracing, change detection, and documentation features in this project.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

code-context-graph AGENTS.md scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

The opening of the file, as written. The whole thing — 158 lines — stays where its author put it; the contents beside it link to each section on GitHub.

code-context-graph

A local code analysis tool that parses codebases with Tree-sitter and builds a knowledge graph.

MCP Server

The ccg MCP server registered in .mcp.json provides 18 tools:

  • parse_project, build_or_update_graph, run_postprocess
  • get_node, search, describe, query_graph, list_graph_stats, list_namespaces, get_minimal_context
  • get_impact_radius, trace_flow, list_cross_refs
  • detect_changes, get_affected_flows, list_flows
  • get_annotation
  • get_doc_content

ccg serve is the local stdio MCP entry point. Self-hosted HTTP mode is provided by the separate ccg-server binary, which serves /mcp, /health, /ready, /status, and /webhook. Webhooks are enabled in ccg-server when allowed repositories are configured with the --allow-repo flag. Per-repository branch filtering: --allow-repo "org/api:main,develop" (glob patterns; defaults to main/master when omitted). Compatible with GitHub (X-Hub-Signature-256) and Gitea (X-Gitea-Signature, X-Gitea-Event). Push event pipeline: receive push event -> automatic clone/pull -> graph build -> DB persistence. Graceful shutdown: SIGINT/SIGTERM propagates context cancellation to in-progress clone/build work.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
