Custom skills for Claude Code. Each skill gives Claude a specific behaviour — triggered automatically from context, or invoked manually as a slash command.
Skills
| Skill | What it does |
|---|---|
| checkpoint | End-of-session handoff — writes a one-line entry to CHECKPOINTS.md plus a matching git commit (subject = same line, body = full narrative). Next session reads the index first, opens full commit bodies only for the matches |
| verify | Audits Claude's own output against the user's original request. PASS/PARTIAL/FAIL per requirement, flags scope creep |
| plan-challenger | Stress-tests implementation plans before execution — researches alternatives, challenges complexity, returns a revised plan |
| perspective | Strategic reality check — checks whether the solution already exists, whether there's a better approach, against live docs not stale training data |
| cc-audit | Audits a project's Claude Code setup against official Anthropic docs across 9 areas, produces a scored AUDIT-REPORT.md |
| coherency-check | Cross-document and cross-code coherency analysis — finds contradictions, conflicting values, and overlapping definitions, resolves each interactively |
| philosophier | Compresses verbose text into the shortest precise phrasing that preserves every constraint. Searches for established philosophical principles (YAGNI, Chesterton's Fence, Occam's Razor) when they're exact matches; falls back to raw distillation otherwise |
| website-audit | SEO, AEO, GEO, and structured-data audit. Crawls with Playwright, runs Lighthouse, checks Perplexity citations, scores deterministically |
| interactive-qa | Interactive Q&A that collects your decisions when agents present multiple options or disagree. Plain-language choices, recommendation flagged, dissent between agents surfaced. Produces a brief for Plan Mode, a specialist agent, or just context |
