ai-conductor: Skill for Claude Code

.agents/skills/write-tests/SKILL.md

write-tests is a skill for Claude Code, Codex from jstoup111/ai-conductor. It costs 78 tokens per session (1,908 once invoked), scanned A, original, Apache-2.0.

Repository-specific guidance for designing and reviewing tests, including unit, integration, acceptance, and smoke tests. It explains when to isolate external services and how to choose the narrowest test that proves the behavior.

In plain words
What is it for?
Use it when adding, changing, reviewing, or debugging tests in the ai-conductor repository. It helps decide test scope, mocks, fixtures, performance checks, and CI-compatible setup.
Why use it?
It prevents tests from starting repeated agent runs, leaving worker processes behind, contacting real third-party services, or making the normal test suite unnecessarily slow.

Skill for Claude CodeCodex

Written for Claude Code and Codex: disable-model-invocation in frontmatter, but also agents/openai.yaml present. Also seen: installed under .agents/ (shared by several agents); mentions Codex.

This is jstoup111/ai-conductor's own configuration. It tells Claude Code and Codex how to work on ai-conductor 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 ai-conductor 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

write-tests scanned grade A with 1 finding 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 17d 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.

Makes network callslowCapability

Not a fault in itself. Listed so you know the mod talks to something, and to what.

- Do not spawn `claude`, `codex`, `gh`, `curl`, `wget`, `npm install`, `npm ci`, or `bin/setup` in ordinary tests.

Write Tests

Design tests for this repository. Use the provider-neutral tdd skill separately when implementing behavior test-first.

1. Classify the test

Choose the narrowest level that proves the behavior.

  • Unit: Exercise one function, class, transition, or adapter contract. Inject dependencies and mock every process, network, LLM, GitHub, filesystem boundary not under test.
  • Integration: Exercise real collaboration between selected internal components. Use real temporary files or local Git only when they are the boundary under test. Fake all third-party services.
  • Acceptance: Exercise an observable story or gate across the minimum real internal path. Fake third-party boundaries; create only the authoritative artifacts the scenario requires.
  • Smoke: Exercise a real executable or third-party service. Put it under src/conductor/test/smoke/ or name it *.smoke.test.ts. Smoke tests are excluded from the ordinary suite.

Only explicit smoke tests may call real Claude, Codex, GitHub, package registries, HTTP services, or other third parties.

2. Select the seam before writing the fixture

Name the exact behavior and terminal observation first. Test that seam directly.

  • Prefer exported pure helpers for selection, classification, ordering, and state calculations.
  • For an engine-native boundary, invoke the smallest method that owns the behavior.
  • Use Conductor.run() only when the test must prove orchestration across multiple steps.
  • Never use a full conductor run merely to prove plugin registration, provider invocation, marker contents, configuration resolution, event emission, or one state transition.

If the assertion can be made without completing the full workflow, the test MUST stop at that boundary.

3. Bound every Conductor fixture

Before calling Conductor.run(), write down:

  1. The first step that may run.
  2. The exact steps expected to dispatch.
  3. The condition that ends the run.
  4. Every completion artifact or gate verdict required before that endpoint.

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.

write-tests is a skill published in the GitHub repository jstoup111/ai-conductor (7 stars, last pushed today), licensed Apache-2.0. It adds 78 tokens to every session and 1,908 once invoked, about $0.0003 per session on Opus 5.5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
