Summary

Adds an original Cursor Project Rule for operating Agent QA through an already configured MCP server or installed CLI. The rule covers test scoping, evidence capture, failure classification, self-heal review, scoped fixes, and honest reporting.

Contribution Type

  • New Cursor rule file or rules folder
  • Update/fix to an existing rule
  • New rules/*.mdc rule
  • Documentation or README cleanup

Value To Cursor Users

The rule gives Cursor a reusable, safety-bounded workflow for turning requested user behavior into Agent QA runs and handling the evidence correctly. In particular, it distinguishes product defects, test defects, environment failures, and inconclusive runs before permitting a fix.

Added Or Changed Files

  • rules/agent-qa-testing.mdc — the scoped Agent QA operating rule
  • README.md — canonical self-repo link under Testing

Quality Checklist

  • The contribution includes original rule content, or clearly credits the source.
  • New rule files use a descriptive kebab-case filename, such as react-typescript.mdc.
  • New rules/*.mdc files include frontmatter with a non-empty description, relevant globs, and alwaysApply: false unless the rule is universal.
  • README links use canonical GitHub URLs for repo files and point to the correct category.
  • The text is neutral and useful, not sales copy.
  • This is not a standalone external tool, product, directory, marketplace, or service listing.
  • No secrets, tokens, affiliate links, tracking links, or unrelated product claims are included.
  • I checked for duplicate or near-duplicate existing entries.

Notes For Maintainers

The rule is original content informed by Agent QA's public documentation and source workflows: https://github.com/vostride/agent-qa. It deliberately discovers commands from the installed version instead of inventing CLI flags, and it does not auto-initialize or mutate an Agent QA workspace.

Validation:

  • all 84 repository tests pass
  • npm run check:awesome-list
  • npm run check:repo-hygiene
  • npm run check:repo-security
  • git diff --check

Summary by CodeRabbit

  • Documentation
    • Added an Agent QA Testing entry to the testing documentation.
    • Documented evidence-based QA workflows, deterministic testing practices, sensitive-data handling, failure classification, scoped fixes, rerun expectations, and factual reporting requirements.
    • Improved discoverability of the new QA guidance through a direct reference in the testing section.

Fix the frontmatter glob before merging.

The globs value currently begins with an unquoted *, which can make the frontmatter invalid for YAML-based parsers. Even if accepted, **/* broadly attaches this non-universal rule and conflicts with the rule's request-scoped behavior. Quote the value or leave globs empty to rely on description-based activation.

references.
- Around line 14-15: Update the Agent QA guidance around the configured MCP
server and the fallback in agent-qa mcp to require reading and using the
existing MCP configuration’s exact command, arguments, and transport; when MCP
is unavailable, invoke the locally installed agent-qa package through the
repository’s package-manager runner before consulting its --help output, without
inventing commands or flags.

Review fixes are in f509666. In addition to the two inline items, the catch-all glob was replaced with a quoted, scoped array covering the Agent QA config, default test/suite paths, hooks, and local Agent QA state. Repo hygiene, repo security, and all 84 tests pass.
