OpenCode rejects YAML array form `tools: [Read, Grep, Bash]` on startup (Expected object | undefined). Strip the tools line on copy into ~/.config/opencode/agents/; OpenCode falls back to default tool set and cavecrew subagent prompts already self-restrict in the body.

Fixes #386
Summary
OpenCode rejects YAML array form
tools: [...]for subagent frontmatter and refuses to boot:installOpencode()inbin/install.jscopiedagents/cavecrew-*.mdverbatim into~/.config/opencode/agents/. Three files affected:cavecrew-investigator.md,cavecrew-builder.md,cavecrew-reviewer.md.Fix
New helper
bin/lib/opencode-agent.jsexportsstripOpencodeAgentTools(content)that removes thetools:line (inline-array form and multi-line YAML list form) from the leading frontmatter block. Installer's section 3 now reads → strips → writes instead ofcopyFileSync.OpenCode allows omitting
toolsentirely; it then falls back to its default tool set. The cavecrew subagent prompts already self-restrict in the body ("Read-only locator", "NoBashavailable", etc.), so dropping the array form is safe.Source files in
agents/are left untouched — they keep the Claude Code schema for the Claude Code plugin path. Transform applies only on the OpenCode copy.Verification
Baseline (main): 47 pass / 4 fail / 51 total — 4 pre-existing opencode failures (caveman-compress.md missing in
src/plugins/opencode/commands/, separate issue).Post-fix: 56 pass / 4 fail / 60 total — 9 new tests, zero regressions, same 4 pre-existing failures.
