description	On-demand cleanup of CPM session state files. Exhaustively lists every progress file and its compact-summary companion with age and session label, then deletes only the files you name — no staleness filter, no sentinel, always confirmed first. Triggers on "/cpm:clean".

Clean Session State

Delete leftover CPM session-state files on demand. This is the exhaustive, user-driven counterpart to the passive once-per-session Stale-Progress Check: where the safety-net surfaces only stale other-session files at most once per session, /cpm:clean lists every progress file and compact-summary companion every time it runs — regardless of age, session, or whether the safety-net has already fired — and removes exactly the ones you choose.

Interactive-only. /cpm:clean is always user-initiated and is never part of autonomous execution (cpm:ralph and other autonomous loops never invoke it). It deletes nothing without showing you the file first and getting your confirmation.

This skill is stateless: it creates no progress file of its own (it is the tool that removes them).

Input

Parse $ARGUMENTS:

• No arguments (the common case): run the full interactive flow below — list, then ask what to remove.
• File names / session IDs given: treat them as the user's selection, but still list everything first (Step 1) and confirm the concrete paths (Step 3) before deleting. Arguments are a convenience, never a licence to skip the confirmation.

Process

Step 1: List every session-state file (exhaustive)

Call the shared classifier in list-all mode — it is the single source of truth for the file inventory and labels, so this skill never globs or stats files itself:

CPM_SESSION_ID="$CPM_SESSION_ID" bash "${CLAUDE_PLUGIN_ROOT}/hooks/lib/progress-classify.sh" "" list-all

The empty first argument is deliberate: it lets the classifier resolve the project root itself ($CLAUDE_PROJECT_DIR → git rev-parse --show-toplevel → $PWD) while still placing list-all in the mode slot. Do not pass "$CLAUDE_PROJECT_DIR/docs/plans" here. That variable is set for hooks, which Claude Code spawns, but not for the Bash calls a skill issues — so the argument expanded to a bare /docs/plans, and this step reported an empty inventory on every run.

It emits one tab-delimited record per file — CLASSIFICATION<TAB>PATH<TAB>SKILL<TAB>PHASE<TAB>AGE_SECONDS<TAB>AGE_LABEL — for both .cpm-progress-*.md files and .cpm-compact-summary-*.md companions. Apply no staleness filter and consult no sentinel: CURRENT, FRESH, and STALE files are all listed and all eligible for deletion. The classification is shown only as context, not as a gate.

If there are no records (no files exist): report "No CPM session-state files found in docs/plans/ — nothing to clean." and stop. Do nothing else — an empty inventory means there is nothing to act on, never a reason to touch anything.

Otherwise, present a numbered inventory. Group each compact-summary companion with its progress file by shared session ID (.cpm-progress-{id}.md and .cpm-compact-summary-{id}.md belong to session {id}). Show, per entry: the session ID, skill + phase (progress files; companions read "compact summary"), the age label, and the path. List any compact-summary with no matching progress file as an orphan on its own. Mark the current session's own files (CURRENT) with a note — "this session's active state" — so the user does not remove them by accident.

Step 2: Ask what to remove

Ask which files (or session groups) to delete — by number, session ID, or "none". Everything listed is eligible; nothing is pre-selected. If the user names a session/progress file that has a compact-summary companion, that companion is part of the same unit and will be removed with it (shown explicitly in Step 3). If the user chooses "none" (or names nothing), stop without deleting anything.

Step 3: Confirm the exact paths, then delete only those

Expand the user's selection into the concrete list of file paths to remove — each chosen progress file plus its compact-summary companion — companions are always cleaned together — and any orphan companions named directly. Show the user this exact list of paths and get explicit confirmation before removing anything. On confirmation, delete only those paths:

rm -f -- "<path>"   # for each confirmed path

Delete nothing the user did not name and confirm. After removal, report which files were deleted (and that any others listed were left untouched).

Guidelines

• Exhaustive, every time. No sentinel, no once-per-session gate, no age threshold — /cpm:clean always lists the full inventory. That is the difference between it and the passive safety-net.
• Delete only named, confirmed files. The user always sees the exact paths before anything is removed; no path in this skill auto-executes a delete.
• Companions travel with their progress file. Removing a session's progress file also removes its .cpm-compact-summary-{id}.md, surfaced in the confirmation so it is never a surprise.
• Thin consumer of the classifier. File discovery, age, and labelling come from progress-classify.sh in list-all mode — do not re-implement globbing or stat here, so the rules never drift from the hooks and the safety-net.
• Interactive-only. Never invoked by autonomous loops; always user-driven.
