Codex adapter for opencode-swarm test authoring rules. Use before creating or modifying any test file in this repository, especially bun:test files, mock.module usage, _internals seams, temp directories, cross-platform tests, or CI-sensitive test structure.
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
# Writing Tests Use this Codex-facing adapter before touching tests in `opencode-swarm`. Read, in order: 1. `AGENTS.md` 2. `.opencode/skills/writing-tests/SKILL.md` If the task also touches architecture, plugin initialization, subprocesses, tool registration, plan durability, `.swarm` storage, runtime portability, session/global state, guardrails/retry, chat/system hooks, or release/cache behavior, also load `.agents/skills/engineering-conventions/SKILL.md`. Codex-specific execution notes: - Use `apply_patch` for manual test/source edits. - Use the available shell execution tool for `bun --smol test`, per-file loops, `rg`, and validation commands. - Prefer shell test commands for repo validation. Do not use broad OpenCode `test_runner` scopes. - Preserve unrelated user changes in the worktree. Carry forward the source skill's core rules: `bun:test` only, dependency injection or `_internals` over `mock.module` where possible, real module spreading when mocking Node built-ins, `os.tmpdir()` plus `path.join(...)` for temp paths, and per-file isolation for mock-heavy directories. Regression tests must also be falsifiable: remove or bypass the fix, confirm the …

How to install
mdr add zaxbyhub/opencode-swarm/writing-tests@sha256:dd18a92543c4690cThe 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.
