Agent-Context: Instructions file for Claude Code

CLAUDE.md

Agent-Context CLAUDE.md is an instructions file for Claude Code from lx-wnk/Agent-Context. It costs 1,475 tokens per session, scanned A, original, MIT.

Repository instructions for Agent-Context, a framework that gives coding agents shared project guidance through CLAUDE.md and AGENTS.md files.

In plain words
What is it for?
They help agents work on the framework, format files, run checks, and understand its layered context and file-ownership rules.
Why use it?
They explain how the project is structured, which files are maintained centrally, and which commands check formatting and tests. This reduces accidental edits to files that automatic updates may replace.

Instructions file for Claude Code

Written for Claude Code: the file is CLAUDE.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions Claude Code.

This is lx-wnk/Agent-Context's own configuration. It tells Claude Code how to work on Agent-Context 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 Agent-Context 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

Agent-Context CLAUDE.md scanned grade A 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 29d 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.

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Project Overview

Agent-Context is a layered, agent-agnostic context architecture for AI coding agents. All layers (0-3) load at startup via @-includes in AGENTS.md, keeping the always-on baseline at ~150-200 effective instruction lines (enforced by tests/check-token-budget.sh). Detailed reference (skills, memory files, delegation/memory-maintenance procedures) is pulled on-demand based on task keywords.

This repository contains the framework itself: shared context files, templates, setup/update prompts, and documentation. It is not a runtime application — it's a template system installed into other projects via install.sh, which runs a headless agent on .prompts/setup-prompt.md.

Commands

# Format all files
npm run prettier:fix

# Check formatting (CI-style)
npm run prettier

# Run all tests
npm test

Architecture

File Ownership Model

Four categories of files, critical to understand before editing:

  • Shared files (context/, incl. context/bin/, context/hooks/, context/skills/, and context/commands/, plus .prompts/memory-review-prompt.md and .prompts/decision-review-prompt.md): Overwritten on every update in target projects. Changes here propagate to all installations. Includes the discovery-map and budget-check skills, and the Claude Code slash commands in context/commands/ (discover, memory-review, decision-review → .claude/commands/) — thin wrappers that invoke the matching skill/review prompt.
  • Template files (templates/): Copied once during setup, never overwritten. These become project-owned files (incl. hooks.conf, budget.conf).
  • Test files (tests/): CI tests verifying install.sh behavior, template coverage, token budget, memory-prune, hooks, and an offline install smoke test (check-install-smoke.sh, derived from the setup-prompt download table). tests/lib.sh holds shared helpers sourced by the test scripts. Not installed into target projects.
  • Repo tooling (scripts/*.mjs): Node checks that run only in this repo and CI — the always-on budget gate and the baseline measurement, each with node:test tests. Never installed; installs measure with the budget-check skill instead.
  • Generated artifacts (outputs/): Reports produced by skills — review findings, handoffs, audits, analyses. Git-ignored, never installed, never referenced by shared files or tests. Regenerate rather than edit; deleting the directory must never break anything.

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.
