prune

**one sweep for every ref already spent:** merged branches named, unmerged left alone - prunes dead tracking refs, then reports the trunk delta - preserves unmerged branches and names only the merged ones - deletes nothing; every deletion is handed back as a command you run # Instructions ## Telemetry ```! "${CLAUDE_PLUGIN_ROOT}"/skills/prune/prune.sh $ARGUMENTS echo "sidecar exit: $?" ``` - `help: requested` → the run was refused before it started; `## Help` below is the whole turn - it already ran, so there is no command to issue - fail (`sidecar exit` > 0) → abort and report: "<raw terminal error>" - success (`sidecar exit` = 0) → report "/gitgud:prune telemetry" and continue to step 1 1. run the native shell command exactly as specified ```bash plugins/gitgud/shared/triage.sh ``` - fail (`sidecar exit` > 0) → abort and report: "<raw terminal error>" - success (`sidecar exit` = 0): merge its classification into the handover, then STOP NEVER run a deletion, and never offer to; handing the commands over IS the deliverable step 1 already caught the gone and merged branches; this step exists for the ones `git branch --merged` cannot see, since a rebased branch reads merged = no forever read `merged = yes OR absorbed = yes` as "safe"; only `merged = no AND absorbed = no` is real unmerged work ```text - ignored: `main` and `production` are never deleted - skipped: merged = no AND absorbed = no, the only branches holding unshipped...
