agtrace: Instructions file for Claude Code

CLAUDE.md

agtrace CLAUDE.md is an instructions file for Claude Code from lanegrid/agtrace. It costs 1,432 tokens per session, scanned A, original, Apache-2.0.

An instruction file for an AI coding agent working on agtrace, a Rust-based tool that records and analyzes AI-agent activity. It defines required project workflows, coding rules, and the repository structure.

In plain words
What is it for?
Use it to orient work in the agtrace codebase, which collects logs from agents such as Claude Code, Codex, and Gemini into a common timeline. The excerpt also requires checking available tasks and using a pull-request workflow.
Why use it?
It gives the agent the project's rules before it changes code, including how commands must be run and how changes should be submitted.

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 lanegrid/agtrace's own configuration. It tells Claude Code how to work on agtrace 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 agtrace 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

agtrace 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 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.

CLAUDE.md

This file provides guidance for Claude Code when working in this repository.

Required

  • Always load /git-workflow first regardless of the conversation topic (before any other task)
  • Before starting work -> mise tasks to see available tasks
  • All commands MUST be run via mise run (works from any directory)
  • Prefer root-cause fixes over shortcuts (step back, reflect, take the senior engineer approach)
  • All changes go through PRs via /git-workflow (never commit directly to main)
  • Commit messages must be one-line, Conventional Commits format
  • Write everything in English (OSS project)

Project Overview

Rust-based local-first observability platform for AI agents. Normalizes diverse agent log formats (Claude Code, Codex) into a unified AgentEvent timeline.

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.
