The `.opencode/commands/*.md` frontmatter referenced agents with the Claude
Code plugin namespace (`agent: everything-claude-code:<name>`), but ECC's
opencode integration registers its agents unscoped in `opencode.json`'s
`agent` map (`code-reviewer`, `planner`, ...), and that file's own `command`
section already references them unscoped. The `everything-claude-code:` scope
resolves under no opencode config (the opencode plugin package is
`ecc-universal`, and inline-config agents are bare), so subtask commands like
`/code-review` hard-fail with `Agent not found: everything-claude-code:code-reviewer`.
Non-subtask commands fall back to the default agent and appear to work — which
is why only some commands failed.
Strip the `everything-claude-code:` prefix from all 30 command frontmatter
agent ids so they match the registered agents, fix the MIGRATION.md example,
and replace the test that enforced the broken scoped invariant with one that
asserts each command agent id is a registered opencode agent (fails on the old
scoped ids, passes on the fix).
Fixes#2477
Major OpenCode integration overhaul:
- llms.txt: Comprehensive OpenCode documentation for LLMs (642 lines)
- .opencode/plugins/ecc-hooks.ts: All Claude Code hooks translated to OpenCode's plugin system
- .opencode/tools/*.ts: 3 custom tools (run-tests, check-coverage, security-audit)
- .opencode/commands/*.md: All 24 commands in OpenCode format
- .opencode/package.json: npm package structure for opencode-ecc
- .opencode/index.ts: Main plugin entry point
- Delete incorrect LIMITATIONS.md (hooks ARE supported via plugins)
- Rewrite MIGRATION.md with correct hook event mapping
- Update README.md OpenCode section to show full feature parity
OpenCode has 20+ events vs Claude Code's 3 phases:
- PreToolUse → tool.execute.before
- PostToolUse → tool.execute.after
- Stop → session.idle
- SessionStart → session.created
- SessionEnd → session.deleted
- Plus: file.edited, file.watcher.updated, permission.asked, todo.updated
- 12 agents: Full parity
- 24 commands: Full parity (+1 from original 23)
- 16 skills: Full parity
- Hooks: OpenCode has MORE (20+ events vs 3 phases)
- Custom Tools: 3 native OpenCode tools
The OpenCode configuration can now be:
1. Used directly: cd everything-claude-code && opencode
2. Installed via npm: npm install opencode-ecc
