Worktree support

[olivoil]

When running in a worktree, the qmd collection is reported as missing, because the name of the collection is derived from the worktree path instead of the repo root.

repoRoot() uses git rev-parse --show-toplevel, which returns the worktree directory. collectionName() calls basename() on that, so each worktree gets a unique collection name instead of sharing one. ghost status reports the collection as missing, and MCP search falls back to querying all qmd collections (returning unrelated results from other projects).

This seems like a bug?

Also, each worktree gets its own .ai-sessions/ instead of being shared in the repo root. I'm not sure if this is intentional, it could be more of an issue for the completed sessions that are lost on worktree cleanup?

Hey @olivoil - Thanks for reporting this! ghost is super early stage so you might actually be the first person to try it out! Really appreciate you taking the time.

For the projects I have been dogfooding ghost on, I have not been using work trees, & this was definitely a bug. The root cause was using git rev-parse --show-toplevel which returns the worktree path, not the main repo. So yeah, everything was getting scoped to the worktree instead of being shared.

Should be fixed now in #5 ghost update will pull it in.

One heads up: new worktrees won't have the hook config unless you either commit .claude/settings.json and .mcp.json, or run ghost enable per worktree. There's a section in the README now that covers the options.

Let me know if anything else comes up!
