Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.01583 | $0.01583 |
| Opus 5 | $0.00792 | $0.00792 |
| Sonnet 5 | $0.00317 | $0.00317 |
| Haiku 4.5 | $0.00158 | $0.00158 |
Grade A, and why
K-LEAN CLAUDE.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 5d 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.

CLAUDE.md
This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.
Project Overview
K-LEAN is a multi-model code review and knowledge capture system for Claude Code. It provides consensus reviews from multiple LLMs via LiteLLM proxy, a persistent per-project knowledge database with hybrid semantic search, and 8 specialist agents for domain-specific analysis.
Package name: kln-ai (PyPI)
Entry points: kln (main CLI), kln-smol (agent executor)
Development Commands
IMPORTANT: Always use the project venv at .venv/. System python lacks required dependencies (platformdirs, psutil, etc.) and will fail on import.
# Install in editable mode
pipx install -e .
# Run tests (MUST use .venv)
.venv/bin/pytest tests/ -v
.venv/bin/pytest tests/unit/test_hooks.py -v
.venv/bin/pytest tests/unit/test_hooks.py::TestClassName::test_method -v
# Lint (MUST use .venv)
.venv/bin/ruff check src/
.venv/bin/ruff check src/ --fix
# Format
.venv/bin/black src/
# Sync data files to ~/.claude/ after editing data/*
kln admin sync
# Check installation health
kln doctor -f

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.

K-LEAN CLAUDE.md is an instructions file published in the GitHub repository calinfaja/K-LEAN (36 stars, last pushed 6mo ago), licensed Apache-2.0. It adds 1,583 tokens to every session, about $0.0079 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
