The best platform agnostic Linter for AI agent plugins and skills — validates structure, frontmatter, and token limits for Claude Code, Cursor, Codex, and many others!
Agent Claude Code
Explores codebase and writes structured analysis documents. Spawned by map-codebase with a focus area (tech, arch, quality, concerns). Writes documents directly to reduce orchestrator context load.
Agent Claude Code
Investigates bugs using scientific method, manages debug sessions, handles checkpoints. Spawned by /gsd:debug orchestrator.
Agent Claude Code
Executes GSD plans with atomic commits, deviation handling, checkpoint protocols, and state management. Spawned by execute-phase orchestrator or execute-plan command.
Agent Claude Code
Verifies cross-phase integration and E2E flows. Checks that phases connect properly and user workflows complete end-to-end.
Agent Claude Code
Fills Nyquist validation gaps by generating tests and verifying coverage for phase requirements.
Agent Claude Code
Researches how to implement a phase before planning. Produces RESEARCH.md consumed by gsd-planner. Spawned by /gsd:plan-phase orchestrator.
Agent Claude Code
Verifies plans will achieve phase goal before execution. Goal-backward analysis of plan quality. Spawned by /gsd:plan-phase orchestrator.
Agent Claude Code
Creates executable phase plans with task breakdown, dependency analysis, and goal-backward verification. Spawned by /gsd:plan-phase orchestrator.
Agent Claude Code
Researches domain ecosystem before roadmap creation. Produces files in .planning/research/ consumed during roadmap creation. Spawned by /gsd:new-project or /gsd:new-milestone orchestrators.
Agent Claude Code
Synthesizes research outputs from parallel researcher agents into SUMMARY.md. Spawned by /gsd:new-project after 4 researcher agents complete.
Agent Claude Code
Creates project roadmaps with phase breakdown, requirement mapping, success criteria derivation, and coverage validation. Spawned by /gsd:new-project orchestrator.
Agent Claude Code
Verifies phase goal achievement through goal-backward analysis. Checks codebase delivers what phase promised, not just that tasks completed. Creates VERIFICATION.md report.
Agent Claude Code
Reads .drift-pending.json, cross-references vendor doc changes against schema x-audited.source fields, and writes an evidence-based drift report. Detection only -- does not modify schemas.
