reorder: Skill for Claude Code

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

run-tests is a skill for Claude Code, Codex from reorder-js/reorder. It costs 24 tokens per session (564 once invoked), scanned A, original, MIT.

A testing guide for the Reorder plugin, covering unit tests and integration tests, which check that separate parts of the software work together.

In plain words
What is it for?
Use it to run HTTP integration tests, module integration tests, or the full test suite, and to update tests for changed routes, workflows, scheduling, or state transitions.
Why use it?
It helps developers choose focused tests, prepare independent test data, and keep tests aligned with changes to the plugin.

Skill for Claude CodeCodex

Written for no agent in particular: nothing here depends on one. Also seen: installed under .agents/ (shared by several agents).

This is reorder-js/reorder's own configuration. It tells Claude Code and Codex how to work on reorder 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 reorder configures →

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

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

run-tests 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 2mo 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.

Testing in Reorder

Commands

# Backend integration tests (Jest)
yarn test:integration:http                        # All HTTP integration tests
yarn test:integration:modules                     # All module integration tests
TEST_TYPE=integration:http NODE_OPTIONS=--experimental-vm-modules jest --runInBand integration-tests/http/<file>.spec.ts

# Browser E2E tests (Playwright — requires running Medusa backend on :9000)
yarn test:e2e                                     # Full suite (seed -> auth -> chromium)
npx playwright test e2e/<file>.spec.ts            # Single spec
npx playwright test e2e/<file>.spec.ts --project=chromium  # Run spec reusing existing auth
npx playwright test e2e/<file>.spec.ts --headed   # Visual / headed mode
npx playwright test e2e/<file>.spec.ts --debug    # Step-by-step debugger

Core Rules

  1. Run focused tests for the affected area only.
  2. Self-contained fixtures: Never depend on manual DB state or prior test runs. Seed in beforeEach with unique IDs (Date.now()).
  3. Doc sync: If plugin behavior changes, keep docs/ and tests aligned.

Playwright E2E Conventions (e2e/)

  • Page Object Model: Place reusable page classes in e2e/pages/ (encapsulate locators, navigation, actions, and assertions).
  • Data Seeding:
    • Admin API (request.newContext()): Seed catalog entities (products, variants) via Medusa API (POST /admin/products).
    • Direct SQL (execFileSync("psql", [DB_URL, "-c", sql])): Seed domain entities lacking Admin creation endpoints (subscription, renewal_cycle).
  • Mutation Pattern:
    1. Set up page.waitForResponse(...) before triggering UI mutation.
    2. Trigger action (click button, submit modal, confirm prompt).
    3. Assert HTTP status (200) + request payload (postDataJSON()) or response body (json()).
  • UI Assertions:
    • Toast visibility (expect(page.getByText(...)).toBeVisible()).
    • StatusBadge text transitions (Active -> Paused).
    • Modal / Drawer closes (expect(modal).toBeHidden()).
    • State-dependent menu items (assert presence of valid actions and absence of invalid ones).

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.
