Claude Skills — PDLC Role Collection

Comprehensive, standards-grounded Claude Code skills for every role in the Product Development Lifecycle.

454 skills and 173 commands across 57 plugins for 8 roles.

What Makes This Different

Every skill is built on three principles:

1. Standards-grounded — Each role maps to recognized professional bodies of knowledge (SWEBOK, TOGAF, OWASP, AIPMM). See STANDARDS.md.
2. LLM error mitigation — Every skill has an Anti-Patterns section targeting documented LLM failure modes (hallucination, over-generalization, constraint blindness, happy-path bias).
3. Artifact-producing — Every skill produces a concrete deliverable (document, diagram, decision record, test plan, policy), not just advice.

Skills vs Commands

• Skills are domain knowledge units (nouns). They teach Claude about a topic — like writing an ADR, designing a threat model, or creating a product roadmap.
• Commands are workflows (verbs). They chain multiple skills together — like running a full architecture review or planning a product launch.
