Why

Drafts & sent is a marketplace plugin today (squareup/agents buzz-plugins/plugins/drafts-sent). It answers two questions people keep asking the app: "what did I start and not send?" and "did anyone reply after my last message?" Shipping it bundled and enabled by default puts it in every community's sidebar without an install step.

What

• A Drafts & sent page after Activity in the sidebar, with the number of unsent drafts in the current community as its badge.
• Drafts lists the viewer's saved composer drafts for this community, newest change first. Selecting one opens its conversation (a thread draft opens at the thread root). It reads only this device's saved drafts and never changes them.
• Sent lists the viewer's latest 100 messages, grouped by day, as they read now (latest edit applied, deletions dropped). Each row shows who replied after yours ("2 after you") or that you were last ("You're last"); a channel post shows its reply count. A "N with replies after yours" pill summarises conversations waiting on you.
• Search filters both lists by conversation name and what you wrote. Refresh rereads channels, sent messages, conversation context and deletions.

How

Ports the plugin onto host-owned helpers instead of a parallel implementation: listDraftViews/subscribeView and the composer's mentionDraft/hasDraftContent for drafts, threadReference, messageAuthor/deletionApplies, identity names, plainText previews, and relativeTimestamp. UI uses the design system (PanelHeader, SearchField, InlineHeader, NavigationItem, AvatarStack, EmptyState, LoadingRegion) and semantic tokens only.

Status is only ever derived from a complete read of a conversation: a view that is loading, failed, capped at its limit, or near the host's retention caps shows no status rather than a wrong "You're last". Deletion reads run alongside their targets and are rebuilt as one read past eight small ones. Relay-signed messages in the viewer's name count as the viewer's.

Registration: src/bundled/index.ts (enabled by default), sidebar order and Tabler send icon in src/app/shell/presentation.ts, Settings catalog icon.png (a rendered placeholder in the Activity icon's style; a designer should replace it), README for the catalog, and a buzz-help entry.

Screenshots

Captured from this branch's web shell in Chromium against the plugin's simulated demo relay (fictional people and channels), with a thread reply left unsent so Drafts has an entry. The sidebar entry shows the draft count; the Sent header shows how many conversations have replies after yours.

Local build

bin/just desktop-bundle on this branch succeeded and produced target/debug/bundle/macos/Buzz.app (169 MiB). The packaged app was not launched against a live relay.

Testing

• New tests in src/bundled/drafts-sent/ (30): sent/thread/edit/deletion rules, conversation context and activity, draft reading (scoped, legacy follow-up seeds excluded, 500 cap, unreadable records, change times without text), and page behaviour (badge, drafts/continue, day groups, live updates, Retry, identity switch and view disposal, status pills, readiness across reloads, relay-signed replies, deletion view lifecycle and Refresh, retention and read caps, post + reply as one conversation, deleted own reply).
• src/app/pages.integration.test.mjs updated for the new bundled page (count and registration order).
• crates/plugin-manager/src/lib.rs: the native bundled catalog lists the new manifest and buzz.drafts-sent as enabled by default, so native_catalog_matches_desktop_bundles stays in step with src/bundled/index.ts (cargo test -p buzzodz-plugins --locked passes).
• tests/browser/layout.spec.mjs: the sidebar destination list includes the new row, accepting its draft count beside the label; both affected journeys pass locally in chromium and webkit.
• Rebased onto main 8230222 (after the Inbox → Activity rename in feat(inbox): rename to Activity and simplify the filter bar #2543). Full vitest run passes via the pre-push hook. pnpm check (tsc + Biome) and pnpm design:check pass; pre-commit and pre-push hooks pass.

Human test steps

1. Open a community, type something in a channel composer and in a thread reply without sending, then open Drafts & sent from the sidebar. Both appear under Drafts, newest first, and the sidebar badge shows 2. Select the thread draft: the thread opens at its root with your draft in the composer.
2. Send a message in a channel and have someone (or an agent) reply after you. Under Sent the message shows "1 after you" with their avatar; reply yourself and it becomes "You're last".
3. Switch communities: the page and badge show that community's drafts and sent messages only.

Not yet exercised: a packaged release build. Locally, cargo test --workspace passes every test and then SIGSEGVs at process exit on this machine, including on main; CI's Rust job is the reference.

🤖 Read the registration, drafts reader, and badge code. It stays read-only over composer drafts and stores only a fingerprint for change times. One thing to check: anyone who already installed the marketplace drafts-sent plugin will now see two Drafts & sent pages, so decide whether that needs a migration or a retirement note.
