Agent Instructions

This repository contains a Bun/TypeScript CLI that converts Claude Code plugins into other agent platform formats.

Working Agreement

• Branching: Create a feature branch for any non-trivial change. If already on the correct branch for the task, keep using it; do not create additional branches or worktrees unless explicitly requested.
• Safety: Do not delete or overwrite user data. Avoid destructive commands.
• Testing: Run bun test after changes that affect parsing, conversion, or output.
• Output Paths: Keep OpenCode output at opencode.json and .opencode/{agents,skills,plugins}.
• ASCII-first: Use ASCII unless the file already contains Unicode.

Adding a New Target Provider (e.g., Codex)

Use this checklist when introducing a new target provider:

1. Define the target entry

   • Add a new handler in src/targets/index.ts with implemented: false until complete.
   • Use a dedicated writer module (e.g., src/targets/codex.ts).

2. Define types and mapping

   • Add provider-specific types under src/types/.
   • Implement conversion logic in src/converters/ (from Claude → provider).
   • Keep mappings explicit: tools, permissions, hooks/events, model naming.

3. Wire the CLI

   • Ensure convert and install support --to <provider> and --also.
   • Keep behavior consistent with OpenCode (write to a clean provider root).

4. Tests (required)

   • Extend fixtures in tests/fixtures/sample-plugin.
   • Add spec coverage for mappings in tests/converter.test.ts.
   • Add a writer test for the new provider output tree.
   • Add a CLI test for the provider (similar to tests/cli.test.ts).

5. Docs

   • Update README with the new --to option and output locations.

When to Add a Provider

Add a new provider when at least one of these is true:

• A real user/workflow needs it now.
• The target format is stable and documented.
• There’s a clear mapping for tools/permissions/hooks.
• You can write fixtures + tests that validate the mapping.

Avoid adding a provider if the target spec is unstable or undocumented.
