mock-to-internals-migration

mock-to-internals-migration is a skill for Codex from ZaxbyHub/opencode-swarm. It costs 59 tokens per session (208 once invoked), scanned A, original, MIT.

A migration guide for replacing Bun’s shared module-mocking approach with dependency-injection seams in opencode-swarm tests.

In plain words
What is it for?
Use it when changing tests that use mock.module, adding injectable test seams, fixing isolation failures, or updating source modules to support controlled dependencies.
Why use it?
It helps prevent mock state from leaking between tests and makes individual dependencies easier to replace safely during testing.

Skill for Codex

Written for Codex: agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents); mentions Codex; mentions OpenCode.

Good fit Use it when changing tests that use mock.module, adding injectable test seams, fixing isolation failures, or updating source modules to support controlled dependencies.

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

mock-to-internals-migration 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 11d 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

Mock To Internals Migration

Read .opencode/skills/generated/mock-to-internals-migration/SKILL.md for the canonical migration protocol.

Also load:

  1. .agents/skills/writing-tests/SKILL.md
  2. .agents/skills/engineering-conventions/SKILL.md if the seam touches runtime-sensitive code

Codex-specific execution notes:

  • Use apply_patch for source and test edits.
  • Use focused per-file bun --smol test <file> --timeout 30000 validation first.
  • Restore any _internals overrides in afterEach.
  • Prefer small seams that expose only the dependency under test.
Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.
