Instructions file for CodexOpenCode

Written for Codex and OpenCode: the file is AGENTS.md.

This is bricerising/enterprise-software-playbook's own configuration. It tells Codex and OpenCode how to work on enterprise-software-playbook 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 enterprise-software-playbook 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

enterprise-software-playbook 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 7d 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.

What it actually says

Agent Instructions (enterprise-software-playbook)

This repo is itself an opinionated system for writing agent skills. To prevent drift, follow the repo specs.

Repo Structure

  • skills/ — one directory per skill, each containing SKILL.md (frontmatter + body) and optional references/
  • specs/ — specifications, decision records (specs/decisions/), templates, and skills-manifest.json
  • tools/ — bundled tool implementations (e.g., tools/archobs/, tools/intelligence/), each a self-contained project
  • .system/ — internal tooling: skill creator scripts, doc generation, CI templates

Start Here

  • Read specs/000-index.md (index) and specs/004-change-process.md (how to make changes).
  • Taxonomy and default workflow live in specs/003-taxonomy-and-workflow.md.

Change Rules (High Signal)

  • Treat skill names as API: prefer stable names; if you rename, capture it in a decision record and update docs (specs/002-skill-contract.md).
  • For non-trivial changes, add/update a decision record in specs/decisions/.
  • Keep skills concise; put depth in references/ (progressive disclosure).
  • Prefer cross-links between skills over duplicating content.
  • Keep specs/skills-manifest.json aligned with each skill's frontmatter metadata (stage, tags) and maintain manifest-only fields (trigger, related, overhead).

Verification

  • Validate changed skills: python3 .system/skill-creator/scripts/quick_validate.py skills/<skill-folder>
  • Validate repo-level docs/workflow consistency: python3 .system/skill-creator/scripts/check_repo_consistency.py
  • Keep README.md and PROMPTS.md aligned with the workflow-stage grouping (Define/Standardize/Harden/Verify).

Packaging (Optional)

  • Package skills to dist/ (build output): python3 .system/skill-creator/scripts/package_skill.py skills/<skill-folder> ./dist
Changes

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.
