Key Changes Summary
This PR delivers Story #99 ("Implement task with skills") across 3 commits and 138 files (+1458/−1046). The changes fall into 5 categories:
- 3 new skill files:
/implement(process),/verify-quality(capability),/record-decision(capability) - 2 new standalone templates: ADR and ADL
- How-to-10 thinning: reduced from ~457 to ~181 lines, now acts as orchestrator that delegates to
/implement - Link processor code change: disabled
normalizedFullpath conversion, added tests - Batch link conversion: 128 files converted from
.pair/-prefix links to correct relative paths
Business Value Validation
The PR delivers the core value of Story #99: extracting operational detail from how-to-10 into composable skills, enabling AI agents to execute structured implementation workflows. The how-to → skill separation follows the approved design decision (skill = operational detail, how-to = orchestrator). Delivers the core skill infrastructure required for agent-assisted development.
Code Review Checklist
Functionality Review
- Requirements Met - All 3 skills from the story scope are implemented; how-to-10 is thinned; link conversion is complete

- Integration - Skills compose correctly:
/implementcomposes/verify-quality(required),/record-decision(required),/assess-stack(optional),/verify-adoption(optional) - Error Handling - Graceful degradation documented in all 3 skills; HALT conditions are clear and actionable
- Performance - No runtime performance regressions; minor dead-code path in link-processor noted (see Issues)
Code Quality Assessment
- Readability - Code is clear and easy to understand
- Maintainability - Orchestrator/skill separation eliminates duplication; dead call chain in link-processor is a minor concern (see Issues)
- Reusability -

Technical Standards Compliance
- Style Guide - Follows established coding standards and KB authoring patterns (YAML frontmatter, markdown structure)
- Architecture - Aligns with the approved skill architecture (process/capability split, composition tables, graceful degradation) and ADR-005
- Design Patterns - check-skip-act-verify pattern applied consistently across all skills
- Dependencies - No new runtime dependencies introduced
- API Design - N/A (KB content, not API)
- Database - N/A

Detailed Review Comments
Positive Feedback
What's Done Well:
- Skill structure is excellent. All 3 skills follow a consistent, scannable format: YAML frontmatter → one-liner → composition table → phased algorithm → output format → composition interface → graceful degradation → notes. This is a strong template for future skills. (Both reviewers)
- Directory structure in
.skills/is clean and follows ADR-005 perfectly. (Antigravity) - How-to-10 thinning is well executed. The how-to retained its identity as orchestrator ("When
/implementis available, invoke it") without duplicating the skill's operational steps. The reduction from 457→181 lines is significant while preserving all essential context. The integration is natural and doesn't invalidate the manual process. (Both reviewers) - The link conversion is comprehensive and correct. 128 files + 3 new skill files + how-to-10 all use consistent relative paths. 59 links verified, zero broken. (Claude)
- Unit tests cover edge cases well, including cross-directory normalization. (Both reviewers)
- Test design follows project conventions. Using
InMemoryFileSystemServiceand realistic file structures for the link processor tests. (Claude) - Commit history is clean. 3 focused commits with clear messages following the
[#99] type: descriptionpattern. (Claude)
Issues to Address
Critical Issues
None.
Major Issues
None.
Minor Issues
-
link-processor.ts:229-285 — Dead call chain.
tryPushFullNormalization→handleFullNormalizationstill computesrelToDocs, checks conditions, handles single-file normalization, and eventually calls the guttedtryPushMultiFileNormalization. The intermediate methods still execute computation that will never produce a replacement for the multi-file case. Consider either: (a) adding a comment at thetryPushFullNormalizationentry point explaining the flow is partially disabled, or (b) short-circuiting earlier. Not blocking — the behavior is correct and the disabled method has a clear comment. -
way-of-working.md:13-14 — Quality Gates section uses placeholder text. The section reads
[Quality gate command, e.g., pnpm quality-gate]and[list sub-checks, e.g., ...]. Since this is an adoption file (not a template), it should contain actual project values. Consider filling inpnpm quality-gateand the actual sub-checks (type checking, testing, linting, formatting) or deferring to a follow-up task if this is intentional. -
SKILL.md (implement):12 — "5-phase cycle" is ambiguous. Line 12 says "Each task follows a 5-phase cycle: context → branch → implementation → quality → commit" but the document structure has Phase 0 through Phase 3 (4 phases). The "5-phase cycle" appears to describe the per-task sub-steps within Phase 2, not the story-level phases. Consider clarifying to avoid confusion — either "4-phase process" at the story level or explicitly labeling the per-task sub-steps.
Questions
- link-processor.ts:311-326 — Is the plan to eventually remove
tryPushMultiFileNormalizationentirely, or is the disabled body intentional for potential re-enabling? If permanent, the method and its call chain could be simplified. If temporary, a// TODO:comment might help track it.
Suggestions and Improvements
Architecture Suggestions
- The 3 skills could benefit from a shared "Composition Interface" section format that's identical across all capability skills. Currently
/verify-qualityand/record-decisionboth have this section but with slightly different structures. A minor standardization opportunity for future skills.
Best Practices
- Monitor the
/implementskill usage in practice to see if further refinements are needed. (Antigravity)
Risk Assessment
Technical Risks
| Risk | Impact | Probability | Mitigation |
|---|---|---|---|
| Batch link conversion regression | Medium | Low | All 59 links verified against filesystem; link-processor tests cover the normalization change |
| Dead code in link-processor | Low | Low | Functionally correct; cosmetic concern only |
Business Risks
None identified. This is a KB content change with no runtime impact on the pair CLI.

PR Information
PR Title: [#99] feat: implement task with skills (/implement, /verify-quality, /record-decision)
Story/Epic: Story #99 (Epic #97)
Type: Feature
Priority: High (P0)
Assignee: @gianlucacarucci
Labels: feature, skills, knowledge-base
Summary
What Changed
Three P0 skills for the implementation workflow:
/implement(process): 5-phase task implementation cycle with TDD discipline, commit strategies, and PR creation/verify-quality(capability): Quality gate checker reading from way-of-working adoption and quality-standards guidelines/record-decision(capability): ADR/ADL recorder with mutually exclusive decision types and mandatory adoption updatesCross-cutting fix: disabled
normalizedFullin link-processor and batch-converted 731.pair/-prefix links to correct relative paths across the dataset.Why This Change
Story #99 delivers the core implementation skills that allow AI agents to implement user story tasks following a structured, repeatable process. These skills compose capability skills (verify-quality, record-decision) and read adoption files to adapt to project-specific decisions. The normalizer fix ensures links are navigable in IDEs and GitHub —
.pair/-prefix paths were non-standard and broke skill distribution.Story Context
User Story: As a product software engineer, I want
/implementto guide the AI through a structured implementation workflow so that tasks are completed with consistent quality and proper decision recording.Acceptance Criteria: All 5 ACs met — skill frontmatter valid, check→skip→act→verify pattern used, composition interfaces declared, how-to-10 thinned to orchestrator role, graceful degradation for optional skills.
Changes Made
Implementation Details
/implement: 5-phase process (Story Analysis → Setup → Task-by-Task → Final Commit → PR). Composes /verify-quality (required), /record-decision (required), /assess-stack (optional), /verify-adoption (optional). Idempotent re-invocation, HALT conditions, graceful degradation./verify-quality: 5-step quality gate checker (Lint → Type Check → Tests → Aggregate). Reads quality gate command from way-of-working.md. Independent gate execution — failure in one doesn't block checking others./record-decision: ADR/ADL mutually exclusive recorder. Architectural → ADR + adoption update. Non-architectural → ADL + adoption update. Date-based file naming.
