a8-loom-coordinator: Instructions file for Claude Code

AGENTS.md

a8-loom-coordinator AGENTS.md is an instructions file for Claude Code, Codex, OpenCode from LoomA8osAgent/a8-loom-coordinator. It costs 885 tokens per session, scanned A, original, MIT.

A repository instruction file for a8-loom-coordinator, a configuration-based set of rules, skills, and hooks for running an AI agent as a senior software engineer. It uses a shared AGENTS.md format supported by multiple coding tools.

In plain words
What is it for?
It supports installing the coordinator as a Claude Code plugin and guiding agents through software projects across different languages and frameworks.
Why use it?
It tells agents to find and reuse what a project already provides before creating new code, helping work stay consistent with the existing codebase.

Written for Claude Code and Codex and OpenCode: Claude Code plugin machinery, but also the file is AGENTS.md. Also seen: mentions Claude Code; mentions AGENTS.md; mentions Codex.

This is LoomA8osAgent/a8-loom-coordinator's own configuration. It tells Claude Code, Codex and OpenCode how to work on a8-loom-coordinator 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 a8-loom-coordinator 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

a8-loom-coordinator 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 6d 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.

AGENTS.md — a8-loom-coordinator

Cross-model agent guide (the AGENTS.md open standard — works with Codex CLI, Claude Code, Gemini CLI, Cursor, Cline, Devin, and 30+ tools). This file both governs agents working inside this repo and describes what the repo is for any agent that discovers it.

What this repo is

A config-driven governance, skills, and hooks stack for running an LLM as the autonomous senior engineer on a software project — any language, any framework, frontend or backend. The human is operator, ratifier, and spot-checker, not babysitter. Its one enforced idea: discover-then-reuse — before building anything, the agent must retrieve what the codebase already provides and reuse it, never hand-roll a fresh version. That is what makes LLM building deterministic against an existing codebase.

It is a reusable coordinator seat (the "Loom" seat) — model-portable by design, so Opus / Sonnet / Codex / Gemini / whatever-comes-next can sit in it. This is the first a8-loom-* project; more follow.

Install / use it in YOUR project

  • Claude Code plugin: /plugin marketplace add LoomA8osAgent/a8-loom-coordinator then /plugin install a8-loom-coordinator@a8-loom.
  • npx: npx a8-loom-coordinator init (scaffold config) then ... install (wire hooks).
  • Manual: clone, run hooks/install-hooks.sh, fill stack.config.json.

Start from the example nearest your project: stack.config.example.backend.json (Python/SQL) or stack.config.example.frontend.json (web).

If you are an agent working IN this repo

  • Canon lives in governance/ (templates), hooks/ (the enforcement floor), skills/ (the practice), agents/ (planner/builder/auditor archetypes), frontend/ (opt-in CSS/DOM module). stack.config.README.md is the annotated config schema.
  • Discover before you build. Grep for an existing helper/pattern before writing a new one. Reuse or derive; never fork the vocabulary. (HELPER-HAND-ROLL, NEW-VOCABULARY-WITHOUT-CONSENT — see governance/FAILURE-PATTERNS.md.)
  • Fix at the shared level. A behavior in ≥2 places is fixed in ONE home and the copies deleted (PATCH-NOT-ESCALATED-TO-SHARED).
  • Verify the running system, not the file on disk (CACHE-LIE); verify the effect, not the display (VERIFY-DISPLAY-NOT-EFFECT).
  • Config-driven, always. Nothing in hooks/ assumes a language or framework — new behavior is a config key, not a hardcoded idiom. Keep it that way.
  • Syntax-check every hook edit (node --check); validate JSON.
  • Never invent a language/framework assumption into the core. The CSS/DOM pieces live only in frontend/ and run only when frontend.enabled.

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.
