This PR enhances the testing-skills-with-subagents skill with a comprehensive Output Quality Validation framework and improves the README installation instructions.

Motivation and Context

The testing-skills-with-subagents skill was missing a critical validation dimension: output quality. While the skill effectively validated that agents follow processes under pressure (process compliance), it didn't validate whether the skill actually produces better work (output effectiveness).

This creates a false confidence problem: an agent can follow all steps, complete all checklist items, and still produce poor quality work. For example, an agent testing a "verification-before-completion" skill might claim "tests pass" without ever running them.

Additionally, the README installation instructions needed clearer formatting and step separation for better user experience.

How Has This Been Tested?

  • The Output Quality Validation framework has been integrated into the skill structure
  • The framework provides clear metrics and comparison methodology (WITH vs WITHOUT skill)
  • README changes have been verified for clarity and correct command syntax

Breaking Changes

No breaking changes. This is purely additive:

  • Adds new "Output Quality Validation" section to existing skill
  • Enhances existing checklist with quality validation items
  • Improves README formatting without changing functionality

Types of changes

  • Bug fix (non-breaking change which fixes an issue)
  • New feature (non-breaking change which adds functionality)
  • Breaking change (fix or feature that would cause existing functionality to change)
  • Documentation update

Checklist

  • I have read the MCP Documentation
  • My code follows the repository's style guidelines
  • New and existing tests pass locally
  • I have added appropriate error handling
  • I have added or updated documentation as needed

Additional context

The Output Quality Validation framework introduces:

  • WITH vs WITHOUT comparison methodology - Systematically comparing output quality with and without skills
  • Quality metrics definition - Clear standards for what constitutes "quality output" for different skill types
  • Output evaluation framework - Distinguishing volume from quality, effort from effectiveness
  • Real-world effectiveness testing - Verifying skills solve actual problems, not just theoretical ones
  • Integration with RED-GREEN-REFACTOR - Quality validation fits into each phase of skill testing

This complements the existing pressure testing framework, ensuring skills are both pressure-resistant AND produce quality output.

Summary by CodeRabbit

  • Documentation
    • Emphasized output quality alongside pressure testing as required criteria for bulletproof skills.
    • Added an "Output Quality Validation (CRITICAL)" section with dual-dimension validation, metrics, WITH-vs-WITHOUT comparisons, and guidance on real-world effectiveness.
    • Integrated explicit quality-validation checkpoints into the RED–GREEN–REFACTOR workflow and checklists.
    • Expanded example workflows to demonstrate quality-focused comparisons, metrics, and pass/fail verdicts.

Addresses critical gap: skill focused too much on time pressure scenarios
and not enough on validating quality of output.

Changes:
- Added major "Output Quality Validation (CRITICAL)" section (~250 lines)
- Distinguishes process compliance from output quality
- Provides WITH vs WITHOUT comparison framework
- Defines quality metrics for different skill types
- Includes quality validation checklist
- Warns about volume ≠ quality
- Shows how to test real-world effectiveness
- Integrates quality validation into RED-GREEN-REFACTOR cycle

Updated:
- Description to mention "produce quality output"
- Testing Checklist with quality validation items in each phase

This ensures skills are tested for effectiveness, not just compliance.

166-415: New Output Quality Validation section is comprehensive and well-integrated.

The framework clearly articulates the critical distinction between process compliance (agents follow the skill) and output quality (the skill actually improves work). The WITH vs WITHOUT comparison methodology, skill-specific quality metrics, and RED–GREEN–REFACTOR integration provide practical, actionable guidance that addresses the stated gap in the existing testing approach.

The section is logically structured, includes realistic examples for TDD, verification, and planning skills, and reinforces that both pressure testing and quality validation are required for a skill to be "bulletproof." This is a valuable addition to the skill.


568-568: Checklist updates align well with new Output Quality Validation framework.

The additions to the testing checklist properly embed quality validation into each phase:

  • Line 568: Measurement of baseline output quality in RED phase
  • Line 574: Verification of output quality improvement in GREEN phase
  • Line 581: Updated description now correctly includes "with violation symptoms" (typo fixed)
  • Line 585: Reference to Output Quality Validation section as final validation step

These updates reinforce that quality assessment is not optional and integrate naturally into the RED–GREEN–REFACTOR flow.

178-178: Add hyphen to compound adjective.

"poor quality work" should be "poor-quality work" (hyphenated when used as a compound adjective before a noun).

- **Still produce poor quality work** ✗
+ **Still produce poor-quality work** ✗

352-352: Consider replacing "under stress" with "under pressure" for consistency.

Lines 352 and 354 use "under stress" which is flagged as potentially wordy. Since the document uses "pressure" extensively (pressure scenarios, pressure types, pressure testing), replacing "under stress" with "under pressure" would improve consistency and slightly improve conciseness:

- **Pressure testing alone:** Proves agent follows skill under stress
+ **Pressure testing alone:** Proves agent follows skill under pressure

- **Both together:** Proves skill works under stress AND produces quality
+ **Both together:** Proves skill works under pressure AND produces quality

Also applies to: 354-354

166-415: Excellent addition of output quality validation framework—well-structured and highly practical.

The new "Output Quality Validation (CRITICAL)" section is comprehensive and fills a genuine gap. The WITH vs WITHOUT comparison methodology, concrete quality metrics examples, and integration with RED-GREEN-REFACTOR are all valuable. The distinction between process compliance and output effectiveness is clearly articulated, and real-world examples make guidance actionable. The testing checklist updates (lines 568, 574, 585) align well with the new framework.


3-3: Description update effectively communicates the expanded scope.

The updated description now explicitly mentions quality output validation alongside pressure testing, making it clear the skill covers both process compliance and effectiveness—an improvement over the previous version.

- Fix hyphenation: 'poor quality work' → 'poor-quality work'
- Replace 'under stress' with 'under pressure' for consistency
- Convert bold formatting to proper markdown headings (MD036)
- Remove bold formatting from 'Volume ≠ Quality' line

3-3: Comprehensive output quality validation framework well integrated.

The new "Output Quality Validation (CRITICAL)" section effectively addresses the gap identified in the PR objectives—extending beyond process compliance to verify skill effectiveness through actual output quality. The additions:

  • Clearly distinguish process compliance from output quality (lines 194–210)
  • Provide concrete WITH vs WITHOUT comparison methodology (lines 214–238)
  • Define skill-specific quality metrics with actionable examples (lines 245–261)
  • Explain common pitfalls (e.g., volume ≠ quality, lines 267–291)
  • Integrate quality checkpoints into the RED-GREEN-REFACTOR phases (lines 398–414)
  • Update the testing checklist to include quality validation steps (lines 568, 574, 585)

The framework is methodical, grounded in real-world effectiveness testing, and maintains consistency with the TDD philosophy that underpins the skill. The section structure, examples, and checklists are clear and actionable.

Also applies to: 166-415, 568-568, 574-574, 585-585


266-268: Apply the suggested heading formatting to maintain document consistency.

The file shows "Volume ≠ Quality" at line 267 is plain text, while all comparable subsections in the document (lines 251, 257, 265, 293, etc.) use level-4 heading syntax (####). The suggested change correctly aligns this section with the established document structure and addresses the MD036 linting rule.

  #### Evaluate Output, Not Just Effort
  
- Volume ≠ Quality
+ #### Volume ≠ Quality

- Fix typo: 'ith' → 'with' in REFACTOR checklist
- Differentiate duplicate headings to resolve MD024 warnings
  - Add "Quality Metrics" suffix to first set of examples
  - Add "Effectiveness Test" suffix to second set of examples
- Improves clarity and markdown lint compliance

I was trying to use the testing-skills-with-subagents skill to generate what ultimately became this skill: https://github.com/mthalman/superpowers/blob/main/skills/adr-generator/SKILL.md. But the scenarios it was generating were hyper-focused on time constraints to test the skill with. All that did was exercise the ability to trigger the generated skill but did nothing to help ensure the quality of the skill (i.e. does it do what it's expected to do?). After applying these proposed modifications, it was able to generate a set of scenarios that improved both its response to pressure and the quality of the behavior of the skill. The output of https://github.com/mthalman/superpowers/blob/main/skills/adr-generator/SKILL.md demonstrates the testing of these changes.
