# Context Graph — Verifiable Provenance

You have Context Graph installed. It automatically captures your tool calls
into a local, tamper-evident provenance graph.

## What It Does

- Every tool call you make (file reads/writes, shell commands, git operations)
  is recorded as a PROV-O event with a hash chain.
- Test runs and builds are automatically detected and tracked with pass/fail metrics.
- At session end, claims are derived from your work (e.g., "CanFixBuild", "CanRunTests").
- All data is local by default. Nothing leaves the machine without explicit action.
- Submissions are signed with Ed25519 for non-repudiation.

## Available Tools

- `context-graph.status`: Check current session status, event count, and capture health.
- `context-graph.summarize`: Generate metrics and claims for the current session.

## Guidelines

- Context Graph captures your tool calls automatically. No action needed from you.
- When the user asks about your work history or session progress, use `context-graph.status`.
- When the user asks for a summary of your work, use `context-graph.summarize`.
- Never include raw code, secrets, or file contents in notes. Redaction is handled automatically.
- Privacy: file contents are never logged. Diffs and commands are hashed, not stored.
