agentplane-testkit-migration

agentplane-testkit-migration is a skill for Claude Code, Codex from basilisk-labs/agentplane. It costs 49 tokens per session (641 once invoked), scanned A, original, MIT.

Instructions for moving Agentplane tests to the shared @agentplane/testkit library. Testkit is a common set of test helpers and fixtures used across the project.

In plain words
What is it for?
Use them when migrating test helpers, fixing testkit import or build errors, organizing CLI or backend test suites, or selecting shared repository, backend, API, and test-gating utilities.
Why use it?
They replace duplicated local helpers and fix build failures caused by missing or incorrect testkit exports. They also provide a way to split large test suites by scenario.

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

agentplane-testkit-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 5d 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.

Agentplane Testkit Migration

Use This Skill When

  • A task mentions @agentplane/testkit, run-cli.test-helpers, shared fixtures, Vitest wrappers, or test helper duplication.
  • CI/build fails because packages/agentplane/src/testing/* cannot import ../../../testkit/dist/*.
  • A large test file is being split into scenario-focused suites.
  • Tests use local helper clones that should move behind the canonical testkit surface.

Source Of Truth

Prefer exported testkit surfaces over deep imports or local helper copies. Before adding a helper, search for an existing one:

rg -n "tempRepo|mockTaskBackend|mockPrApi|mockConfig|describeWhen|runCliSilent|installRunCliIntegrationHarness" packages/testkit packages/agentplane/src

Migration Steps

  1. Identify the test family: CLI PR flow, task lifecycle, release/upgrade, runner, recipes, Redmine/backend, or scripts.
  2. Replace local setup with canonical testkit helpers:
    • repository setup: tempRepo, git helpers, config writers
    • backend setup: mock task backend helpers
    • GitHub PR setup: mock PR API helpers
    • suite gating: describeWhenEnvPresent, describeWhenNotHook, describeCritical
  3. Keep compatibility exports in packages/agentplane/src/testing/index.ts only as a bridge. The canonical implementation belongs in packages/testkit.
  4. If agentplane build imports from ../../../testkit/dist/*, ensure @agentplane/testkit is built before agentplane.
  5. Remove obsolete shims only after rg proves no imports remain.

Build-Safe Export Checklist

When adding or moving a helper:

  1. Export it from the package-local module where it is implemented.
  2. Export it from the public testkit barrel.
  3. Export compatibility aliases only where existing agentplane tests still depend on them.
  4. Run both focused tests and package builds.

Common failure:

Module "../testing/index.js" has no exported member ...
Cannot find module "../../../testkit/dist/index.js"

Interpretation: the helper was migrated without a complete export chain, or build order skipped testkit.

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.
