| description | Central index for all workspace skills. Invoke when you need to find a specific skill or understand the relationships between skills. |
Root node of the Skill Knowledge Graph. Navigate here to find the appropriate specialized skill.
Default Enabled means: preferred for automatic invocation and daily workflow. Everything else is opt-in unless a mounted role checklist requires it.
| Skill | Lifecycle Phase(s) | Primary Role |
|---|---|---|
| brainstorming | Explorer / Propose | Requirement Engineer |
| task-decomposition-guide | Propose / Review | System Architect |
| writing-plans | Propose / Implement | System Architect / Lead Engineer |
| systematic-debugging | Implement / QA | Lead Engineer / Code Reviewer |
| test-driven-development | Implement | Lead Engineer |
| verify | QA / Archive | Code Reviewer / Knowledge Extractor |
| code-review-checklist | QA | Code Reviewer |
| wal-documentation-rules | Archive | Knowledge Extractor |
| skill-graph-manager | Any (skills change) | Skill Graph Curator |
| java-architecture-standards | Propose / Implement | System Architect / Lead Engineer |
| java-coding-style | Implement | Lead Engineer |
| java-testing-standards | QA | Code Reviewer |
| mybatis-sql-standard | Propose / Implement | System Architect / Lead Engineer |
These are invoked because mounted roles explicitly require them (see .agents/workflow/ROLE_MATRIX.md).
| Skill | Required By Roles |
|---|---|
| cognitive-bias-checklist | Requirement Engineer, System Architect, Devil's Advocate |
| spec-quality-checklist | Requirement Engineer, System Architect, Documentation Curator |
| decision-frameworks | System Architect, Devil's Advocate, Ambiguity Gatekeeper |
| linter-severity-standard | Code Reviewer |
This is the “happy path” routing aligned with mounted roles.
| Phase | Mounted Role(s) | Skills |
|---|---|---|
| Explorer | Requirement Engineer | brainstorming → (cognitive-bias-checklist) → (spec-quality-checklist) |
| Propose / Review | System Architect + Devil's Advocate | task-decomposition-guide → decision-frameworks → (cognitive-bias-checklist) → (spec-quality-checklist) |
| Implement | Lead Engineer + Focus Guard | writing-plans → java-architecture-standards/java-coding-style/mybatis-sql-standard → systematic-debugging/test-driven-development |
| QA | Code Reviewer | code-review-checklist → java-testing-standards → verify/ultraqa |
| Archive | Knowledge Extractor | wal-documentation-rules → verify (evidence summary) |
