Cavecrew

Three subagents that return compressed output to save your main context budget across long sessions. Investigator locates code, builder handles surgical edits on 1-2 files, reviewer audits diffs. The hook is that their tool results come back caveman-style at roughly 60% of vanilla token cost, so you can delegate 20 times instead of exhausting context at 12. Trade prose for structure. If you need architectural commentary or deep rationale, stick with the standard agents. If you just need facts and your session is already running long, this keeps you in the game.

Cavecrew = three subagent presets that answer in ultracave voice (tool runs: one status line in, one out; nothing between routine calls). 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` if installed
Review diff, branch, or file for bugs	`cavecrew-reviewer`
Deep code review with rationale + alternatives	`Code Reviewer` (vanilla) if installed, else main thread
One-line answer you already know	Main thread, no subagent
