+## Bridge skills are seeded into every provisioned worktree
+
+**What it does.** fleetd copies a directory of skill folders into each worker worktree it creates,
+at `<worktree>/.claude/skills/`. A skill folder whose name the target repo already ships is never
+touched — the repo's own copy wins, byte for byte.
+
+**On.** Point `memberSkills:` at the directory:
+
+```yaml
+memberSkills: /Users/dai.ha/LTMS/claude-bridge/.claude/skills
+```
+
+Leave it out and nothing is seeded, which is the old behaviour. This is a deferred key — the
+`GitWorktrees` that reads it is built once at startup, so a change needs a daemon restart.
+
+**Why it exists.** Every brief starts with `Load the <name> skill.`, and outside this repo that
+line was silently a no-op. A member spawned against any other repo — kb on fleet01, for example —
+had no `implementer`, `reviewer` or `hunter` to load, and nothing said so. The skills could not
+travel in the plugin either: `ClaudeCodeLauncher` exports `CLAUDE_CONFIG_DIR`, so a member never
+reads the operator's plugin store. The worktree is the only channel that reaches a member.
+fleetd #362 item 3.
+
+**One thing to know for maintenance.** `core.excludesFile` is **single-valued**. The seeded paths
+are hidden from `git status` by pointing that key at a fleetd-written file, scoped `--worktree` —
+and a worktree-scoped value *replaces* the operator's global one rather than adding to it. The
+first cut of this feature did exactly that, and the consequence was severe: this repo's own
+`.gitignore` does not ignore `target/`, only an operator's global excludesFile does, so every
+worker that ran `mvn clean install` made `target/` untracked. `GitWorktrees.hasUncommitted` counts
+untracked files on purpose (CB-576), so `SessionManager` would have preserved every worktree that
+built, forever, with no error to notice.
+
+So the file is **composed, not replaced**: whatever `core.excludesFile` resolved to beforehand is
+copied in ahead of the seeded patterns, including git's own default (`$XDG_CONFIG_HOME/git/ignore`,
+else `$HOME/.config/git/ignore`) when the key was unset. Measured on merge: removing the
+composition fails 2 tests, and removing just the default-file fallback fails 1.
+
+Two smaller things. The composed content is a **snapshot** taken at seed time, so an operator
+editing their own excludesFile later does not change an already-seeded worktree. And the exclude
+file itself lives under the worktree's private git dir (`git rev-parse --absolute-git-dir`), not in
+the working tree, so it cannot be committed and `git worktree remove --force` deletes it along with
+everything else.
+
+`.git/info/exclude` was rejected as the mechanism, and this is worth knowing before someone tries
+it again: from a linked worktree it resolves to the **common** git dir, so it would have hidden the
+seeded paths in the primary checkout and every sibling worktree too.
