Use when asked to lower an agent's token cost, what caveman has saved, to trim a heavy CLAUDE.md, or to offload re-pasted context into cavemem.1.4K6Caveman Explorejuliusbrussee/cavemanRead-only repository explorer for cold-start orientation, broad cross-file localization, or when a direct search failed. Skip it when the exact file or symbol is already named. Returns path:line citations only; its reads stay out of main context.1.3K3Megacavejuliusbrussee/caveman>1.3K1Safe Refactorjuliusbrussee/cavemanRestructure code while preserving behavior. Use for extraction, consolidation, ownership moves, or cleanup where verification must bracket structural edits.1.3K2Caveman Optimizejuliusbrussee/caveman>1.3K1Investigate Firstjuliusbrussee/cavemanDiagnose ambiguous failures before editing. Use for unknown causes, intermittent behavior, performance regressions, or investigations needing evidence-ranked hypotheses.1.3K2Surgical Patchjuliusbrussee/cavemanFix bugs and small behavior changes at the narrowest responsible layer. Use when regression proof, preserved surrounding behavior, and task-relevant tests matter.1.3K2Verify And Stopjuliusbrussee/cavemanProve existing work meets acceptance conditions without expanding scope. Use for validation-only tasks, completion checks, focused gate runs, and last-mile proof.1.3K2Caveman Evidence Reviewjuliusbrussee/caveman>1.3K1Caveman Managejuliusbrussee/caveman>1.3K1Lean Buildjuliusbrussee/cavemanBuild feature work with high overbuilding risk. Use for new behavior, product slices, or integrations where repository reuse, strict scope, and an explicit stop condition matter.1.3K2Migrationjuliusbrussee/cavemanImplement reversible compatibility-safe transitions. Use for schema, data, API, protocol, configuration, or dependency migrations requiring rollback and preservation proof.1.3K2Caveman Discoverjuliusbrussee/caveman>1.3K1Caveman Setupjuliusbrussee/caveman>1.3K1Backpropjuliusbrussee/cavekit|01Buildjuliusbrussee/cavekit|01Cavemanjuliusbrussee/cavekit|01Cavemanjuliusbrussee/skills>02Checkjuliusbrussee/cavekit|01Context Canaryjuliusbrussee/skillsInstall a per-turn canary signal (e.g. starting every reply with the user's name and a turn counter) so silent context degradation becomes visible the moment it happens, and run a recovery protocol when the canary trips. Use when the user mentions a "canary", "context canary", or "canary check", asks to detect context rot / compaction / drift, says "you stopped using my name" or "did you lose context", asks "how degraded is your context", or wants an early-warning system for long agent sessions.02Deepenjuliusbrussee/cavekit|01Grilljuliusbrussee/cavekit|01Grill Mejuliusbrussee/skillsCalibrated grilling session for stress-testing a plan, design, idea, or decision. First assesses the user's topic knowledge, confidence, and desired pressure level, then asks one question at a time with recommended answers. Use when user says "grill me", "stress-test this", "challenge my plan", "interview me", or wants a plan probed without being overwhelmed.01Interface Kitjuliusbrussee/skills|05Junior To Seniorjuliusbrussee/skillsAdversarial senior-engineer review for agent-generated plans, designs, and architectures. Treats the current output as junior work, constructs a senior reviewer whose domain expertise comes from live codebase research plus web research of current best practices, diagnoses altitude failures (too vague or too granular), then rewrites the plan into a scoped, state-of-the-art version. Use when the user says "junior to senior", "senior review", "review this like a staff engineer", when a plan feels hand-wavy or lost in details, or before committing to any agent-written plan.03Last 20 Percentjuliusbrussee/skills>02Loop Factoryjuliusbrussee/skillsRun a spec-driven agent loop where coding tasks live as markdown specs that move through inbox → active → archive, get implemented by Claude Code or Codex, and pass a review gate before they count as done. Use when the user mentions "loop factory", a "spec-driven loop", an "agent factory", wants repeatable/reviewable agent work, or when a repo has a factory/specs/inbox or factory/specs/active directory. Also covers installing and scaffolding the loop-factory CLI into a project.05Researchjuliusbrussee/cavekit|01Reviewjuliusbrussee/cavekit|01Specjuliusbrussee/cavekit|01
