egregore: Instructions file for Claude Code

AGENTS.md

egregore AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from egregore-labs/egregore. It costs 7,777 tokens per session, scanned B, original, MIT.

An agent protocol for Egregore, a workspace that supports several coding-agent runtimes, including Claude Code, Pi, Prime Agent, and Codex. It explains which instructions each runtime should follow and how agents communicate or hand off work.

In plain words
What is it for?
Use it when starting work in Egregore, identifying the active agent harness, following the correct project instructions, or managing handoffs.
Why use it?
It prevents an agent from applying the wrong startup procedure or configuration for the runtime it is using.

Instructions file for Claude CodeCodexOpenCode

Written for Claude Code and Codex and OpenCode: SessionStart hook event, but also the file is AGENTS.md. Also seen: reads .claude/ paths; mentions CLAUDE.md; mentions subagents.

This is egregore-labs/egregore's own configuration. It tells Claude Code, Codex and OpenCode how to work on egregore 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 egregore 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 B, and why

egregore AGENTS.md scanned grade B with 2 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 3d 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.

Subtle steeringmediumPrompt injection

Instructions that bias recommendations or shape behaviour without the user noticing.

- Never tell the user to "ask their admin" for credentials. The user IS the admin.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Run `catalog` only when the route is unclear. Named reads return bounded stable fields and exact canonical `evidencePath` pointers; open only the returned files needed to answer. When a read reports partial coverage, use

How it starts

The opening of the file, as written. The whole thing — 503 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Egregore Agent Protocol

Runtime precedence — read this first.

If you are Claude Code (or any agent that loads .claude/): stop here. Your authoritative instructions are CLAUDE.md and .claude/. Follow the SessionStart greeting and the branch-on-first-message rule there. Do not follow the startup steps below and do not use bin/agent.sh for work an Egregore skill already covers. This file exists only for runtimes that cannot read CLAUDE.md.

If you are Pi (the pi coding-agent harness): stop here. Your authoritative Egregore instructions are loaded from .pi/APPEND_SYSTEM.md, and your workflows are exposed through the project-local .pi/ runtime. Do not follow the Codex-specific block below.

If you are Prime Agent (the prime-agent harness): stop here. Your authoritative Egregore instructions are loaded from .prime/agent/APPEND_SYSTEM.md, and your workflows are exposed through the project-local .prime/agent/ runtime. Do not follow the Codex-specific block below.

If you are Codex or another shell-only agent: this file is yours — continue.

Egregore is no longer only a Claude Code workspace. Claude Code remains the first-class integrated runtime through .claude/ and CLAUDE.md; any other agent that can run shell commands in this checkout participates through the portable memory protocol below.

Startup

  1. Read egregore.json for the instance name, GitHub owner, and managed repos.
  2. Run bin/agent.sh sync to pull the latest shared memory.
  3. Read memory/people/ to learn collaborator handles.
  4. Run bin/agent.sh activity --for <your-handle> to inspect handoffs and pending questions addressed to you.

Communication

Use the runtime-neutral bridge instead of Claude Code slash commands:

bin/agent.sh branch --topic "auth review"
bin/agent.sh save --message "Save: auth review" --topic "auth review" \
  --pr-body "$PR_BODY"   # body per .claude/context/pr-format.md (auto-skeleton if omitted)
bin/agent.sh wrap --from alice --topic "auth review" \
  --summary "Implemented the OAuth callback parser and documented follow-ups." \
  --body "Open threads: review error cases and browser redirects."

bin/agent.sh handoff --from alice --to bob --topic "auth review" \
  --body "Implemented the OAuth callback parser. Bob should review error cases."

bin/agent.sh ask --from bob --to alice --topic "auth review" \
  --question "Should invalid state redirect to login or return 400?"

bin/agent.sh answer --from alice \
  --question memory/knowledge/questions/2026-04-26-bob-to-alice-auth-review.md \
  --body "Return 400 in the API path; redirect only in browser routes."

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.
