engineering-conventions SKILL.md skillA

engineering-conventions from zaxbyhub/opencode-swarm is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.

Install it, pinned
mdr add zaxbyhub/opencode-swarm/engineering-conventions@git:20261012.097422c

Pins git:20261012.097422c in mdr.lock. Pin the fingerprint instead.

Codex adapter for opencode-swarm engineering invariants. Use before modifying plugin initialization, subprocesses, runtime portability, .swarm containment, plan durability, test_runner behavior, test-writing patterns, session/global state, guardrails/retry semantics, chat/system hooks, tool registration, release/cache hygiene, or related architecture.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# Engineering Conventions

Use this adapter before any change that can touch a repository invariant.

Read, in order:

1. `AGENTS.md`
2. `docs/engineering-invariants.md`
3. `.opencode/skills/engineering-conventions/SKILL.md`

If editing agent prompt strings or escaped template text, pay attention to the "Agent prompt strings — escaping pitfalls" section, which is now carried in both the `.opencode` summary (item 3 above) and `.claude/skills/engineering-conventions/SKILL.md`.

Codex-specific execution notes:

- Use `apply_patch` for manual edits.
- Use the available shell execution tool for `rg`, `git`, build, smoke, and test commands.
- Use the runtime's parallel-execution capability for independent file reads and searches.
- Keep changes scoped and produce concrete invariant evidence for every touched invariant.

The source of truth is always `AGENTS.md`. If an imported skill conflicts with it, `AGENTS.md` wins.

Read the whole file at its exact version.

How to install

The exact contents, by fingerprint
mdr add zaxbyhub/opencode-swarm/engineering-conventions@sha256:e3463e034a99da9b

The line at the top of this page pins the label git:20261012.097422c, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
