Create, review, audit, and list Architectural Decision Records for any software project. Trigger on: "create an ADR", "document this decision", "ADR for...", "what ADRs exist", "review this ADR", "update INDEX.md", architectural trade-offs, or design pivots affecting multiple layers or files. Project-agnostic -- works with any tech stack. Backed by Karpathy principles: think before deciding, simplest sufficient ADR, surgical scope.
Audit Codex skills for visibility flags, deterministic vs non-deterministic steps, and composability opportunities. Reads .Codex/skills/ (or a user-specified path), produces a punch list per skill, then shows proposed rewrites with a changelog. Trigger on: "audit my skills", "review my skill files", "which skills auto-fire?", "find duplicated logic in my skills", "should any skills be internal-only?", or any request to review, improve, or rationalize a set of SKILL.md files. Never modifies any file -- proposes changes and waits for approval.
You MUST use this before any creative work - creating features, building components, adding functionality, or modifying behavior. Explores user intent, requirements and design before implementation.
Decision guide for delegating to caveman-style subagents. Tells the main thread WHEN to spawn `cavecrew-investigator` (locate code), `cavecrew-builder` (1-2 file edit), or `cavecrew-reviewer` (diff review) instead of doing the work inline or using vanilla `Explore`. Subagent output is caveman-compressed so the tool-result injected back into main context is ~60% smaller -- main context lasts longer across long sessions. Trigger: "delegate to subagent", "use cavecrew", "spawn investigator/builder/reviewer", "save context", "compressed agent output".
Ultra-compressed commit message generator. Cuts noise from commit messages while preserving intent and reasoning. Conventional Commits format. Subject ≤50 chars, body only when "why" isn't obvious. Use when user says "write a commit", "commit message", "generate commit", "/commit", or invokes /caveman-commit. Auto-triggers when staging changes.
Compress natural language memory files (AGENTS.md, todos, preferences) into caveman format to save input tokens. Preserves all technical substance, code, URLs, and structure. Compressed version overwrites the original file. Human-readable backup saved as FILE.original.md. Trigger: /caveman-compress FILEPATH or "compress memory file"
Quick-reference card for all caveman modes, skills, and commands. One-shot display, not a persistent mode. Trigger: /caveman-help, "caveman help", "what caveman commands", "how do I use caveman".
Ultra-compressed code review comments. Cuts noise from PR feedback while preserving the actionable signal. Each comment is one line: location, problem, fix. Use when user says "review this PR", "code review", "review the diff", "/review", or invokes /caveman-review. Auto-triggers when reviewing pull requests.
