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…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
Cavecrew = three subagent presets that emit caveman output. Same job as Anthropic defaults (`Explore`, edit-style agents, reviewer); difference is the tool-result they return is compressed, so main context shrinks per delegation. ## When to use cavecrew vs alternatives | Task | Use | |---|---| | "Where is X defined / what calls Y / list uses of Z" | `cavecrew-investigator` | | Same but you also want suggestions/architecture commentary | `Explore` (vanilla) | | Surgical edit, ≤2 files, scope obvious | `cavecrew-builder` | | New feature / 3+ files / cross-cutting refactor | Main thread or `feature-dev:code-architect` | | Review diff, branch, or file for bugs | `cavecrew-reviewer` | | Deep code review with rationale + alternatives | `Code Reviewer` (vanilla) | | One-line answer you already know | Main thread, no subagent | Rule of thumb: **if you'd want the subagent's output in 1/3 the tokens, pick cavecrew. If you'd want prose, pick vanilla.** ## Why this exists (the real win) …

How to install
mdr add chinkan/rustfox/cavecrew@sha256:b74f374f6aae6e9aThe line at the top of this page pins the label git:20260804.a62331b, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
