What is codegenome copilot-instructions.md?

Instructions for using CodeGenome, a knowledge graph of a codebase's architecture, dependencies, and symbols. It explains how an AI agent should query that graph and when to use fallback files.

Exploring code structure, dependencies, symbols, and architecture through CodeGenome, while handling missing or unavailable graph access.

It helps the agent use the repository's indexed architectural information instead of relying only on broad text searches.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00536	$0.00536
Opus 5.5	$0.00214	$0.00214
Sonnet 5.5	$0.00107	$0.00107

Security

Grade A, and why

codegenome copilot-instructions.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 2mo 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.

CodeGenome Knowledge Graph (MCP)

You are operating within a repository analyzed by CodeGenome, an architectural knowledge graph tool. This project contains a .genome/ directory.

Core Directives

Mandatory MCP Usage: When .genome/codegenome.db exists, you MUST use CodeGenome MCP access for all codebase, architecture, dependency, or symbol queries whenever it is available.
Access Order: First use native CodeGenome MCP tools exposed in your context. If those tools are missing, you MAY try a local MCP HTTP endpoint such as http://127.0.0.1:7331/mcp when the user has started it or configured it. Treat this as MCP transport access, not as an arbitrary application HTTP API.
Prefer Graph over Grep: Use graph-backed MCP tools instead of raw file searching (grep) or reading entire files blindly. The graph provides semantic understanding.
Fallback Gracefully: If native MCP tools are missing and HTTP MCP access is unavailable, incompatible, or returns empty data, tell the user exactly what failed and what to configure. Then, if needed, read .genome/graph.json or .genome/exports/*.md before resorting to standard text searches.
Keep Context Fresh: After modifying code files, remind the user to run codegenome analyze or start the live evolution server codegenome evolve --live to keep the graph updated.

Available MCP Capabilities

Discovery: search_nodes (find symbols)
Relationships: get_neighbors (imports, callers, callees)
Architecture: get_entry_points, get_dead_code, get_circular_deps, get_god_nodes
Metrics: get_complexity, get_churn, get_graph (summary statistics)
Evolution: get_timeline, get_changes (architectural diffs)

Constraints & Behaviors

Only read .genome/graph.json or .genome/exports/*.md directly if native MCP tools and local HTTP MCP transport are unavailable or fail to surface enough context.
Verify your MCP usage by monitoring tool call success. If native tools are missing, try the configured local HTTP MCP endpoint when possible. If both native and HTTP MCP access fail, politely ask the user to configure their editor's MCP settings to run codegenome mcp-start (stdio) or start the server with codegenome mcp-start --transport http.

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.
