eden-skills AGENTS.md is an instructions file for Codex, OpenCode from AI-Eden/eden-skills. It costs 1,700 tokens per session, scanned A, original, MIT.

A set of instructions for AI-Eden's eden-skills project. It explains which project documents to read, which sources take priority, and how different development roles should coordinate changes.

In plain words
What is it for?
Use it when implementing, testing, reviewing, or documenting changes in eden-skills, particularly when deciding which specification or project record is authoritative.
Why use it?
It helps an agent resolve conflicting guidance and follow the project's documented process across specifications, status files, roadmaps, and change tracking.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md; mentions Codex.

This is AI-Eden/eden-skills's own configuration. It tells Codex and OpenCode how to work on eden-skills 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 eden-skills 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

eden-skills 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 9d 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

Agent coordination guide for eden-skills. This file is designed for fast recovery after context compression.

1. Read Order (Compression-Safe)

  1. spec/README.md
  2. spec/phase1/SPEC_*.md (Phase 1 CLI behavior contracts)
  3. spec/phase2/SPEC_*.md (Phase 2 architecture contracts)
  4. spec/phase2.5/SPEC_*.md (Phase 2.5 MVP launch contracts)
  5. spec/phase2.7/SPEC_*.md (Phase 2.7 UX polish & lock file contracts)
  6. spec/phase2.8/SPEC_*.md (Phase 2.8 TUI deep optimization & code maintainability contracts)
  7. spec/phase2.95/SPEC_*.md (Phase 2.95 performance, platform reach & UX completeness contracts)
  8. spec/phase2.97/SPEC_*.md (Phase 2.97 reliability, interactive UX & Docker safety contracts)
  9. Current phase's SPEC_TRACEABILITY.md
  10. STATUS.yaml
  11. EXECUTION_TRACKER.md
  12. ROADMAP.md
  13. README.md
  14. trace/ (archived phase records — read only when historical context is needed)

2. Authority Order

When files disagree, follow:

  1. spec/**/*.md
  2. STATUS.yaml
  3. EXECUTION_TRACKER.md
  4. ROADMAP.md
  5. README.md

3. Role Boundaries

  • Builder (GPT 5.3 Codex / GPT 5.4) owns implementation, tests, refactors, and non-strategic doc sync.
  • Architect (Claude Opus 4.6 / Claude Sonnet 4.6) owns taxonomy/rubric/crawler strategy decisions.
  • Builder must not finalize Architect-owned strategy outputs without explicit user instruction.

4. Change Protocol

  1. Update spec/ first for behavior changes.
  2. Implement code to match spec.
  3. Update tests per the current phase's SPEC_TEST_MATRIX.md.
  4. Update the current phase's SPEC_TRACEABILITY.md links for changed requirements.
  5. Update STATUS.yaml and EXECUTION_TRACKER.md.

5. Quick Start Task Routing

Phase 1 (CLI Foundation)

  • If task is CLI behavior or validation: start from spec/phase1/SPEC_COMMANDS.md and spec/phase1/SPEC_SCHEMA.md.
  • If task is target path logic: start from spec/phase1/SPEC_AGENT_PATHS.md.
  • If task is verification scope: start from spec/phase1/SPEC_TEST_MATRIX.md.

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.
