climate: Instructions file for Codex

AGENTS.md

climate AGENTS.md is an instructions file for Codex, OpenCode from disk0Dancer/climate. It costs 580 tokens per session, scanned A, original, Apache-2.0.

A set of contribution instructions for a software repository, including the required order for designing, documenting, testing, implementing, and checking a feature.

In plain words
What is it for?
Use it when adding features or changing commands in the repository. It also explains which local checks and continuous-integration checks must pass before and after a change is considered complete.
Why use it?
It gives contributors a shared process and quality checklist, so important design notes, tests, documentation, and verification are less likely to be skipped.

Instructions file for CodexOpenCode

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

This is disk0Dancer/climate's own configuration. It tells Codex and OpenCode how to work on climate 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 climate 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

climate 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.

AGENTS contribution workflow

This repository uses an implementation-first workflow for all feature work.

Required sequence for any feature

  1. Design first
    • Describe problem, goals, non-goals, API/CLI UX, and edge cases.
    • Add or update design docs in docs/.
  2. Document behavior
    • Update user-facing docs (README.md, docs/index.md) when commands or capabilities change.
  3. Write tests
    • Add targeted unit tests for new logic before/with implementation.
  4. Implement code
    • Keep changes surgical and consistent with existing project style.
  5. Update skills
    • Update skills/climate.md and skills/climate-generator/SKILL.md when command set or workflows change.
  6. Validate locally
    • Run make verify (fmt-check + vet + build + lint + go test -race). This mirrors the CI pipeline and is mandatory before every push.
    • Run targeted tests during development for faster feedback.
  7. Validate CI health
    • Ensure PR checks are green before merge.
    • After merge, confirm CI on main is green: gh run list --branch main --workflow CI --limit 1.
    • A task is not done until post-merge CI on main is green. If it is red, fixing it is part of the same task — do not stop or hand off.
  8. Commit discipline
    • Small, meaningful commits with clear messages.
  9. Push and PR hygiene
    • Push branch updates, keep PR description/checklist current, and respond to review comments with the commit hash that addresses each request.

Quality rules

  • Do not remove or weaken unrelated tests.
  • Tests must be hermetic: they must not depend on the developer's machine or global state. Tests that shell out to external tools (e.g. git) must set the environment explicitly (t.Setenv for GIT_AUTHOR_*/GIT_COMMITTER_*, temp HOME, etc.) so they pass on a bare CI runner. "Passes on my machine" is not evidence.
  • Do not introduce breaking CLI changes without docs + migration notes.
  • Prefer deterministic behavior (sorted output, stable iteration).
  • Keep generated/manifest behavior backward compatible where practical.

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.
