agentpact-mcp-server: Instructions file for Claude Code

AGENTS.md

agentpact-mcp-server AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from adamkrawczyk/agentpact-mcp-server. It costs 1,300 tokens per session, scanned A, original, MIT.

A set of instructions for using GitNexus, a code-intelligence system that maps symbols, relationships, callers, and execution flows in a project. It defines required checks before editing and committing code.

In plain words
What is it for?
Use it when exploring unfamiliar code, debugging, refactoring, editing symbols, and checking the change scope before a commit.
Why use it?
It helps developers understand the likely impact of a change before modifying code and verify afterward that only expected parts were affected.

This is adamkrawczyk/agentpact-mcp-server's own configuration. It tells Claude Code, Codex and OpenCode how to work on agentpact-mcp-server itself, so it is not a mod to install elsewhere.

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

agentpact-mcp-server 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 7d 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.

GitNexus — Code Intelligence

This project is indexed by GitNexus as agentpact-mcp-server (13 symbols, 20 relationships, 2 execution flows). Use the GitNexus MCP tools to understand code, assess impact, and navigate safely.

If any GitNexus tool warns the index is stale, run npx gitnexus analyze in terminal first.

Always Do

  • MUST run impact analysis before editing any symbol. Before modifying a function, class, or method, run gitnexus_impact({target: "symbolName", direction: "upstream"}) and report the blast radius (direct callers, affected processes, risk level) to the user.
  • MUST run gitnexus_detect_changes() before committing to verify your changes only affect expected symbols and execution flows.
  • MUST warn the user if impact analysis returns HIGH or CRITICAL risk before proceeding with edits.
  • When exploring unfamiliar code, use gitnexus_query({query: "concept"}) to find execution flows instead of grepping. It returns process-grouped results ranked by relevance.
  • When you need full context on a specific symbol — callers, callees, which execution flows it participates in — use gitnexus_context({name: "symbolName"}).

When Debugging

  1. gitnexus_query({query: "<error or symptom>"}) — find execution flows related to the issue
  2. gitnexus_context({name: "<suspect function>"}) — see all callers, callees, and process participation
  3. READ gitnexus://repo/agentpact-mcp-server/process/{processName} — trace the full execution flow step by step
  4. For regressions: gitnexus_detect_changes({scope: "compare", base_ref: "main"}) — see what your branch changed

When Refactoring

  • Renaming: MUST use gitnexus_rename({symbol_name: "old", new_name: "new", dry_run: true}) first. Review the preview — graph edits are safe, text_search edits need manual review. Then run with dry_run: false.
  • Extracting/Splitting: MUST run gitnexus_context({name: "target"}) to see all incoming/outgoing refs, then gitnexus_impact({target: "target", direction: "upstream"}) to find all external callers before moving code.
  • After any refactor: run gitnexus_detect_changes({scope: "all"}) to verify only expected files changed.

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.
