lacp: Instructions file for Claude Code

CLAUDE.md

lacp CLAUDE.md is an instructions file for Claude Code from 0xNyk/lacp. It costs 4,078 tokens per session, scanned C, original, MIT.

A project guide for Claude Code, an AI coding assistant, describing the LACP control plane, its files, commands, and tests. LACP is a local system for controlling and checking assistant sessions.

In plain words
What is it for?
Navigating the repository, running full, quick, isolated, or single tests, and working with its shell scripts, policies, hooks, and release files.
Why use it?
It gives the assistant the project’s structure and the correct checks to run instead of relying on assumptions.

Instructions file for Claude Code

Written for Claude Code: SessionStart hook event. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is 0xNyk/lacp's own configuration. It tells Claude Code 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 C, and why

lacp CLAUDE.md scanned grade C with 1 finding 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.

Recursive force deletehighDestructive command

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

How it starts

The opening of the file, as written. The whole thing — 319 lines — stays where its author put it; the contents beside it link to each section on GitHub.

LACP — Local Agent Control Plane

Framework for hardening, orchestrating, and validating Claude Code sessions on local machines.

Key Directories

Path Purpose
bin/ CLI commands (lacp-test, lacp-doctor, lacp-brain-expand, etc.)
hooks/ Claude Code hooks (SessionStart, PostToolUse, Stop)
scripts/lacp-lib.sh Shared shell library — sourced by all bin/ commands
scripts/ci/ CI test scripts (test-*.sh)
scripts/runners/ Pipeline runners (brain-expand steps, etc.)
automation/scripts/ 44 Python + 22 shell automation scripts (brain-expand steps, RAG, benchmarks, sync)
config/ Policy files (sandbox, MCP auth, route policy)
dist/ Distribution/packaging assets
Formula/ Homebrew formula

Running Tests

# Full suite (~60 tests)
bin/lacp-test

# Quick suite (doctor + route policy)
bin/lacp-test --quick

# Isolated (temporary roots, no side effects)
bin/lacp-test --isolated

# Single test
bash scripts/ci/test-<name>.sh

Conventions

  • All bash scripts use set -euo pipefail
  • All bin/ scripts source scripts/lacp-lib.sh for shared functions (log, die, require_cmd, etc.)
  • CI tests use assert_eq pattern — compare actual vs expected, print PASS/FAIL
  • CI tests create temp dirs, trap cleanup EXIT — no leftover state
  • JSON output via --json flag on bin/ commands

Hook Architecture

Hooks live in hooks/ and are installed to ~/.claude/ via bin/lacp-claude-hooks apply-profile.

Hook Event Purpose
stop_quality_gate.py Stop Criteria-based scoring (4 dimensions, weighted avg) + test verification + heuristics + handoff artifact generation
session_start.py SessionStart Git context + test cmd caching + focus brief + handoff injection + stale contract cleanup
eval_checkpoint.py PostToolUse(Write/Edit) Continuous QA — runs tests at intervals during work, injects feedback on failure
pretool_guard.py PreToolUse Co-author, scp/root, rm -rf, publishing, exfiltration guards
thinking_nudge.py UserPromptSubmit Nudges user to state position before asking questions (opt-in)
detect_session_changes.py (library) Scans transcript for file changes (imported by stop hook)
hook_telemetry.py (library) JSONL telemetry logger with rotation (imported by stop hook)
hook_contracts.py (library) Typed state exchange between hooks (SessionStartOutput, SprintContract, EvalCheckpoint, HandoffArtifact)
write_validate.py PostToolUse(Write) YAML frontmatter schema validation
session_orient.sh SessionStart Vault tree, recent changes (legacy bash)
stop_quality_gate.sh Stop Ollama-backed rationalization detection (legacy bash)

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.
