hush:pick-style

Picks which output style hush delivers, and delivers it. Every style listed here carries hush's mechanics — the silence between tool calls, the one structured final message, the hard caps. They differ only in voice and in what the final message is built to do.

Everything below is mechanical: two scripts do the reading, matching, and file-writing. Run their output verbatim — no re-parsing frontmatter by hand, no free-form judgment about which entry the user means.

1. List the shelf and ask for a number

Run:

node "${CLAUDE_PLUGIN_ROOT}/scripts/list-styles.js"

It prints one JSON object: styles (each with index, name, description, source, path, active), plus activeName, activeOnShelf, stockBackupExists, and restoredOverTakeover.

Render it as exactly this table, one row per entry in styles, in index order:

| # | Name | Description | Source | Active |
| --- | --- | --- | --- | --- |
| 1 | <name> | <description> | <source> | ✓ (only on the active row) |

source is stock for the benchmarked default and crafted for the user's own variants. Print it as it comes — it is what tells two same-named entries apart.

If restoredOverTakeover is true, add one line above the table: "A plugin update restored stock Hush over a prior takeover." Otherwise add nothing.

If activeOnShelf is false, add one line above the table instead: "<activeName> is active but its file is no longer on disk — no row below is checked." This means no row in the table will show ✓.

If the invocation already named a style, match it case-insensitively against styles[].name. Exactly one match → skip straight to step 2 with that entry's path, no table shown. No match, or more than one → show the table as above and ask the user to reply with a row number.

End the message with the table (or the skipped-straight-through report) — nothing after it. Wait for the reply.

2. Activate

Take the number from the user's reply and look it up in the styles array from step 1 — a plain index lookup, not a re-read of any file. An out-of-range or non-numeric reply gets the table shown again, unchanged, with no other action taken.

Run:

node "${CLAUDE_PLUGIN_ROOT}/scripts/activate-style.js" "<that entry's path>"

The script checks the chosen style against hush's mechanics first, backs up output-styles/hush.md to output-styles/hush.md.stock on first use, writes the chosen file into the forced slot with force-for-plugin: true added, and strips any outputStyle setting that pointed at the same name. The swap is all-or-nothing: a style that dropped hush's mechanics or answers to stock's own name is refused, and any failure mid-swap puts the previously active style back. The backup is kept, so stock restores as often as it is asked for.

It prints { ok, target, name, backedUp, settingsUpdated, warnings }, or { ok: false, error } on failure — relay an error verbatim rather than retrying. A non-empty warnings comes with a completed swap: the style is active, and each warning names a settings file whose redundant outputStyle is still there for the user to remove by hand. Relay those verbatim too, under the report.

This is the only place in the plugin that touches output-styles/hush.md; craft-style calls this same script rather than repeating the swap.

3. Report

From the script's JSON: which style (name) is now active, that it takes effect next session, and that stock is always the way back. Say plainly that a crafted style is unmeasured — the benchmark numbers belong to stock Hush only.
