Glance — one-line reliability summary

Surface the active feature's reliability in a single line so the user can check stability without context switching.

Trigger

User invokes /mumei:glance (no args) or /mumei:glance <feature>. The skill is disable-model-invocation: true; it never fires on the model's own initiative.

What it does

1. Resolves the target feature:

   • no args → reads .mumei/current for the active feature key
   • with args → uses the given feature key directly

2. Computes pass^3 over the most recent 10 trials via hooks/_lib/reliability.sh.

3. Renders exactly one line to stdout:

   <feature> | pass^3: <value-or-N/A> (n=<n_trials>, window=10, k=3)
   

4. Outputs no active feature to stdout (not stderr) and exits 0 when .mumei/current is missing or stale (REQ-25.2.3).

How to invoke

Run the CLI implementation in scripts/mumei-glance.sh and print its stdout verbatim:

bash "$CLAUDE_PLUGIN_ROOT/scripts/mumei-glance.sh" "${1:-}"

The script always exits 0 (missing active feature is not an error). Do not reformat the output.

Don'ts

• Don't add headers, blank lines, or trailing commentary — the contract is one line.
• Don't emit no active feature to stderr — REQ-25.2.3 specifies stdout.
• Don't accept flags or multiple feature args. A single optional positional arg only.
• Don't re-interpret the numeric value — it is a window pass rate, not a geometric Pass^k.
