OpenCode Compatibility

[Dalanir]

Hi!

Love this project! Would you be down to add OpenCode to Claudisian (even though it seems really tight by the name)?
It would be something that I would be to do!

Resolved by #36, which adds OpenCode support (and Codex/Cursor/Pi as a bonus) via the universal .agents/skills/ layout from the vercel-labs/skills format spec.

Architecture:

• .agents/skills/<name>/SKILL.md is the canonical location, read natively by OpenCode, Codex, and Cursor
• .claude/skills/<name> and .pi/skills/<name> are symlinks pointing at the canonical, so Claude Code and Pi find the same skills
• Edit a skill once at the canonical location, all five agents see the change

This approach supersedes the earlier attempt in #31 (thanks @Dalanir for that PR — your work on OpenCode compatibility helped motivate getting this into a shared multi-agent format rather than an OpenCode-specific shim).
