What is agent-watch AGENTS.md?

Project instructions for Agent Watch, a command-line tool that collects lessons from AI coding chats and updates shared instruction files.

Use them when building, testing, or maintaining Agent Watch and its instruction-file update process.

They keep coding conventions and project knowledge in sync across Claude, GitHub Copilot, and other AI tools.

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.

Model	Per session	Once invoked
Fable 5.1	$0.03137	$0.03137
Opus 5.5	$0.01255	$0.01255
Sonnet 5.5	$0.00627	$0.00627
Haiku 4.5	$0.00314	$0.00314

Security

Grade A, and why

agent-watch 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 2mo 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.

Agent Watch: Development Guide

This document provides guidance for AI agents working on the Agent Watch codebase. It includes project structure, code conventions, testing practices, and key architectural patterns.

Project Overview

Agent Watch is a CLI tool that automatically extracts knowledge from AI chat sessions (Claude Code, GitHub Copilot Chat, Copilot CLI) and updates agent configuration files (CLAUDE.md, AGENTS.md, .github/copilot-instructions.md) to keep them in sync with evolving codebase conventions.

Key responsibility: Keep developer knowledge about project patterns and conventions captured in version-controlled agent instruction files, accessible to all AI tools that assist the team.

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.
