subprocess-safety SKILL.md skillA
subprocess-safety from zaxbyhub/opencode-swarm is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add zaxbyhub/opencode-swarm/subprocess-safety@git:20261030.00ff7e9Pins git:20261030.00ff7e9 in mdr.lock. Pin the fingerprint instead.

Guidelines for safe subprocess calls in opencode-swarm. Load before adding, modifying, or reviewing any file that calls spawn, spawnSync, bunSpawn, or child_process. Covers the six required properties, Windows portability, _internals DI seam pattern, and verification grep.
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
# Subprocess Safety Read, in order: 1. `AGENTS.md` (Invariant 3: subprocesses) 2. `docs/engineering-invariants.md` (subsection 3) 3. `.agents/skills/writing-tests/SKILL.md` if tests are touched 4. `.agents/skills/mock-to-internals-migration/SKILL.md` if converting mock.module to _internals Codex-specific execution notes: - This skill consolidates AGENTS.md Invariant 3 into an actionable checklist. - The canonical spawn shape and six required properties are non-negotiable per AGENTS.md. - The CI quality job enforces these via `bun run check:invariants` (Check 1: subprocess timeout). - Violations are advisory in CI but blocking in code review. ## When to use this skill - You are adding, modifying, or reviewing a subprocess call (`bunSpawn`, `spawn`, `spawnSync`, `child_process.execFile`, etc.) - You are writing or updating tests that exercise subprocess-dependent code - A PR review flags a subprocess call missing timeout, cwd, or cleanup ## Scope This skill applies to all files that spawn child processes: - `src/utils/git*.ts` - `src/hooks/*.ts` - `src/tools/*.ts` - `src/services/*.ts` - `src/plugins/*.ts` - `src/index.ts` (init-path subprocesses) …

How to install
mdr add zaxbyhub/opencode-swarm/subprocess-safety@sha256:4a307a67cfc09381The line at the top of this page pins the label git:20261030.00ff7e9, 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.
