lacp: Instructions file for Claude Code

AGENTS.md

lacp AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from 0xNyk/lacp. It costs 1,400 tokens per session, scanned A, a copy of claude-code-trace AGENTS.md, MIT.

A set of rules for using GitNexus, a code-navigation tool that maps symbols and how parts of a codebase relate.

In plain words
What is it for?
Finding execution paths, checking callers and affected code, reviewing debugging or refactoring changes, and verifying the final change set.
Why use it?
It helps an assistant understand unfamiliar code and estimate which parts may be affected before editing.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: PostToolUse hook event, but also the file is AGENTS.md. Also seen: reads .claude/ paths; mentions Claude Code.

This is 0xNyk/lacp's own configuration. It tells Claude Code, Codex and OpenCode how to work on lacp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything lacp configures →

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

lacp 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 1mo 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.

Origin

This is a copy

83% identical to claude-code-trace AGENTS.md — 113 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.

How it starts

The opening of the file, as written. The whole thing — 102 lines — stays where its author put it; the contents beside it link to each section on GitHub.

GitNexus — Code Intelligence

This project is indexed by GitNexus as lacp (264 symbols, 453 relationships, 13 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/lacp/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.
