What

When someone DMs the bot, it replies with:

Hey, I’m HuddleFM, a music bot. I’m automated, so nobody’s going to read what you send here.

Want to listen to music? Invite me to a huddle, or mention me in a huddle’s thread while you’re in it. I’ll join and send a player in the thread where you can control stuff and add songs. If the player gets buried, mention me again and I’ll repost it.

Your settings live here too: scrobbling, what goes into the Huddle mix, and the data I keep about you. [Open my settings]

• Sent at most once every 10 minutes per person, and never to other bots.
• Integrations' JSON commands by DM work as before. An allowlisted person writing ordinary chat gets the note.

Settings outside a session

The button opens Settings with just the You tab: scrobbling mode and services, the Huddle mix, Last.fm/ListenBrainz accounts, Jellyfin linking and Your data. This used to live only inside a running session's Coordinator, so:

• src/user-settings.ts adds a UserSettings controller for it, routed in onAction by the personal stand-in session ID. It has its own long-lived JellyfinUi for linking.
• The Last.fm dialogs, Your data's contents and data deletion are now shared helpers, used by both the Coordinator and UserSettings.
• The "This session" scrobbling toggle only shows when there is a session.

Running sessions

Changes made from the DM reach any session the user is in straight away:

• A service just turned on starts scrobbling from the current song.
• The Taut/Slick plugins refresh.
• A new scrobbling default ("Default for new Huddles") leaves a session already going as it is. It's pinned only when the default would flip it, written without clearing scrobbles waiting on an "ask" answer.

Testing

• bun run check and bun test pass (877 tests).
• New tests: src/user-settings.test.ts, plus a Coordinator test for keepSessionScrobbling.
• Not tried in a live Slack workspace yet.

Walkthrough

The bot now welcomes users who direct-message it and provides access to personal settings. Users can manage scrobbling and provider connections, view and delete personal data, and have relevant preference changes forwarded to active sessions.

Changes: Personal Settings

Layer / File(s)	Summary
Welcome messages and action routing README.md, src/index.ts	Direct messages receive a welcome with a personal-settings action, subject to a per-user cooldown. Slack actions can route to UserSettings, which is closed during shutdown.
Personal settings and provider flows src/user-settings.ts, src/user-settings.test.ts	UserSettings supports scrobbling and Huddle mix preferences, Last.fm and ListenBrainz connections, and Jellyfin links. Tests cover personal-settings routing, modal updates, and preference submissions.
Active-session preference synchronization src/index.ts, src/coordinator.ts, src/coordinator.test.ts, src/settings-schema.ts, src/user-settings.test.ts	Preference changes notify active coordinators. A participant’s current session scrobbling choice is preserved before a user default changes, and the session setting is shown only when sessionEnabled is defined.
Personal data views and deletion src/user-settings.ts, src/coordinator.ts, src/user-settings.test.ts	Personal data summaries and deletion are handled by shared helpers. Coordinator actions use these helpers, and the Your data dialog is updated after deletion.

Enabling scrobbling can send an inaccurate now-playing update from a Huddle the person has not joined. This is a bounded issue to fix or explicitly accept before merging.

Full details: Title check

Explanation

The title "Answer DMs with how to use the bot and a way into your own settings" matches the main change. The PR adds a DM reply that explains how to use the bot and includes an "Open my settings" button that opens personal settings. The changeset includes the new welcome message in src/index.ts, the new UserSettings controller in src/user-settings.ts, and the README usage note. The title is specific and does not use vague terms. It is a single sentence of 15 words, which is slightly long but still clear.

Full details: Docstring Coverage

Explanation

Docstring coverage is 20.00% which is insufficient. The required threshold is 80.00%. Docstring coverage is scoped to functions touched by this diff with cyclomatic complexity of at least 2. Documentation-only edits and deletions within surviving functions are included; unchanged diff context and fully deleted functions are excluded. Analyzed 5 functions across 6 files. (1 skipped: 1 unsupported.)

Resolution

Write docstrings for the functions missing them to satisfy the coverage threshold.
