DottaandClaude Opus 5.5 7329eaf353 perf(ui): open sidebar Recents tasks from cache (#20450)
## Thinking Path

> - Paperclip is the open source app people use to manage AI agents for
work
> - The board UI sidebar has a Recents list of the tasks a person opened
last
> - The Recents list renders from a local snapshot, but its links had no
warm-up. A click waited for the task-detail code and about nine
first-frame reads
> - Task lists (Inbox, Tasks) already warm a task on hover, press and
click, and #20355 added a batched `chat-bootstrap` read that had no UI
consumer
> - The hosted database is CPU-bound, so a fix must add at most one read
per page load and must not compete with the page's own reads
> - This pull request gives Recents the same open-intent prefetch as
task lists, warms the task-detail code, and preloads the top ten recent
tasks with one `chat-bootstrap` request after the page is idle
> - The benefit is that a click on a recent task shows its chat from
cache, without a wait for the API

## Linked Issues or Issue Description

Refs #20355 (server read this PR consumes). Builds on #20389, #20398 and
#20419.

**Is your feature request related to a problem?**
Opening a task from the sidebar's Recents was slower than opening it
from a task list. The Recents links had no prefetch. The task page
waited for its first-frame reads after the click.

**Describe the solution you'd like**
Recents links use the task lists' open-intent prefetch. When the page is
idle, one batched request loads the first frame of the most recent tasks
into the task page's caches.

**Describe alternatives you've considered**
Per-task prefetch of every recent task. That makes up to ten times nine
requests per page load, which the hosted database cannot afford.

**Additional context**
I searched open PRs and remote branches for "chat-bootstrap" and
"instant task opens". The only related work is the server-side branches
that merged as #20355. There is no other in-flight UI consumer of
`chat-bootstrap`.

## What Changed

- `ui/src/hooks/useIssueNavigationPrefetch.ts`: the open-intent handlers
from `IssueLinkQuicklook` move into one hook (light warm on pass-over;
`history: true` on a resting hover or focus, a mouse or pen press, and a
click). `IssueLinkQuicklook` now uses the hook. Its behavior does not
change.
- `ui/src/components/RecentTaskNavItem.tsx`: one Recents link wrapper
that applies the hook. The classic list (`SidebarRecentTasks`), the
Coordinator task rows and `DesignSidebar` use it. `SidebarNavItem`
accepts the handlers through a new optional `linkHandlers` prop.
- Classic Recents links now open `/issues/<identifier>` (Coordinator
already did). The old UUID link remounted the task page after a redirect
to the identifier route.
- `ui/src/hooks/useRecentTaskOpenWarmup.ts`: when Recents shows a task,
it fires the task-detail code warm-up (`useWarmTaskDetailCode`). After
two frames, a visible tab, no fetching queries and an idle callback, it
sends one `issues/chat-bootstrap?ids=` request for the ten most recent
tasks. It skips tasks whose first frame is cached and fresh. It sends no
request for an empty list or a hidden tab. It sends at most one request
per account per page load. Unmount or an account change aborts the
request.
- `ui/src/lib/issueChatBootstrapCache.ts`: `seedIssueChatBootstrap`
writes each field under the keys the task page reads, for the requested
ref, the id and the identifier: core issue, recent comments, comment
input facts (one batch, through the new `seedIssueIdBatch`), recent
activity, the recent run window (through the new shared
`buildRecentIssueRunWindow`), interactions, attachments, live runs and
active run. An explicit `null` active run is stored. A missing field is
not stored. It does not replace data that is as new or newer, data with
a read in flight, or data with a pending invalidation. Keys whose page
merges observed history (comments, activity, runs, input facts) are
filled only when empty. Items for another company are ignored.
- The seed fills the `?view=core` key, not the full detail key.
`seedIssueDetailCache` is not used: the core payload cannot stand in for
the detail read's related data, and seeding it there would suppress that
read.
- `issuesApi.chatBootstrap` client method.
- `tests/perf/collections/recent-task-open.spec.ts` and its README
section.

## Verification

Local disposable instance (`local_trusted`, production UI build,
embedded PostgreSQL, collection fixture plus 12 comments on each of 8
recent tasks, streamlined UI with the Coordinator sidebar). Journey:
open Projects with 8 Recents, wait for network idle plus 3 s, click a
recent task, measure until its latest comment is on screen. Each run
uses a fresh browser context (empty HTTP cache and storage apart from
Recents). Median of 5 runs, same server and fixture for both arms:

| Arm | Click to first chat frame | Idle page API requests |
| --- | --- | --- |
| `master` (b6f4008f9b), loopback | 227 ms (first run: 249 ms) | 24
(range 21–25) |
| This PR, loopback | 134 ms | 22 (range 21–27) |
| `master`, +150 ms on each API response | 455 ms | 19 |
| This PR, +150 ms on each API response | 135 ms | 20 (+1
`chat-bootstrap`) |

With added latency, the first frame no longer depends on API latency.

- `PAPERCLIP_COLLECTION_PERF_BASE_URL=http://127.0.0.1:<port> pnpm exec
playwright test --config tests/perf/collections/playwright.config.ts
recent-task-open.spec.ts recent-task-summaries.spec.ts`: 5 passed. On
`master` the two assertion cases fail (0 `chat-bootstrap` requests; 10
first-frame reads after the click).
- Reads that still follow a click on a preloaded task: full detail (`GET
/issues/:id`), `work-products`, `documents`, `feedback-votes`,
`tree-control/state`, `tree-holds`, `runner-goal`, `browsers`, and the
`read` mark. The `chat-bootstrap` payload does not cover them. None
gates the chat's first frame (the frame shows at 135 ms while every API
response waits 150 ms).
- Unit tests: `RecentTaskNavItem.test.tsx` (intent levels, href),
`useRecentTaskOpenWarmup.test.tsx` (one request for the top ten, code
warm-up, wait for page reads, hidden tab, fresh entries skipped, once
per account, user isolation, abort on unmount),
`issueChatBootstrapCache.test.ts` (each key in the endpoint shape,
`null` versus missing fields, company isolation, no downgrade of newer,
in-flight or invalidated data, merge keys filled only when empty).
- `ui` Vitest: `src/components src/hooks src/lib src/api` 694 files
passed; `src/pages src/App src/context` 188 files passed. `pnpm
check:token-gates`: clean. `pnpm verify` exits 2 because a `tests/` file
is a global CI input; required CI supplies the broad coverage.

## Risks

- Low to medium. One extra read per page load when Recents has tasks
without a fresh cached first frame. The read starts only after the
page's own queries settle, and the server reads at most two tasks at a
time.
- A live event that arrives while the preload is in flight, for a task
with no cached keys, can leave seeded data up to 30 s old until the next
live event or the next open after the stale time. Inbox hover prefetch
has the same window.
- Classic Recents links now use the identifier route instead of the UUID
route. The task page already redirected UUID links to this route.
- `tests/perf/collections` is a manual suite. CI does not run it.

## Model Used

- Claude Opus 5.5 (`claude-opus-5-5`), Anthropic, in Claude Code with

7b9334cd10 Draft: Build agent-ready design proposal system (#16875)
## Thinking Path

> - Paperclip helps people manage AI agents and their work.
> - People need consistent UI patterns to review and control that work.
> - The current board uses related layouts and controls with different
spacing, type, and behavior.
> - That drift makes it hard for a designer or an agent to build a new
page from a reliable reference.
> - Storybook can show the shared patterns and the states they need to
support.
> - This pull request adds design proposals, a local sandbox, and
reusable UI controls so people can compare the patterns in context.
> - The benefit is a clearer design system that agents can use to build
consistent UI.

## Linked Issues or Issue Description

**Subsystem affected**

`ui/` — React board UI and Storybook.

**Problem or motivation**

Board pages repeat visual and interaction decisions. Storybook did not
provide a complete reference for task views, conversation states,
typography, toolbars, tabs, and light/dark colors. People could not
compare a proposed pattern with the running board in one place.

**Proposed solution**

Add a staged Design Proposals catalog with foundations, components,
layouts, and page specimens. Add an opt-in sandbox. Reuse production
components where possible. Include synthetic conversation states and
shared controls so reviewers can compare and refine them.

**Alternatives considered**

Separate static mockups would not show keyboard behavior, responsive
layout, or real component states. Rebuilding each page only in Storybook
would allow the reference to drift from the board.

**Roadmap alignment**

This improves existing board UI and Skills Manager surfaces. It does not
add a new control-plane capability.

## What Changed

- Added dark and light color references, typography and conversation
specimens, and component stories for buttons, tabs, toolbars, sidebar,
popovers, activity, and task lists.
- Added a local design sandbox with synthetic task conversation playback
and representative states.
- Shared collection toolbars and navigation patterns across task, agent,
project, routine, skill, connector, and artifact pages.
- Added the streamlined Skills tabs and a My Skills collection that uses
the shared skill cards.
- Restored saved-thread access during synthetic playback, kept connector
searchbox semantics, and updated reproduction checks after moving trial
stories.
- Documented the proposed patterns and added focused UI, catalog, and
browser checks.

## Verification

- `pnpm check:token-gates`, `node scripts/check-maps.mjs`, and `node
scripts/storybook-catalog.mjs --check` passed.
- Full workspace `pnpm -r typecheck` and `pnpm build` passed after
merging master. After the review fixes, focused UI typecheck, `pnpm
build-storybook`, 23 Skills Sources tests, and all 15 Storybook
typography browser tests passed.
- Focused task-thread and system-notice suites passed: 251 tests.
Connector Browse passed 84 tests; the connector, attachment, recovery,
and Storybook flyout browser journeys passed locally.
- A local full Vitest run hit one intermittent chat-channels integration
failure; that test passed in isolation. GitHub CI
[39347996059](https://github.com/paperclipai/paperclip/actions/runs/39347996059)
passed on the exact latest commit: 55 successful checks and two skipped
draft-only Storybook jobs.
- Greptile reviewed the exact latest commit at 5/5 with no new comments
or open review threads. GitHub reports the branch as cleanly mergeable.

## Risks

- This PR changes 206 files and exceeds the repository's 100-file review
target. Review by commit and consider a scoped split before merge.
- Design Proposals are staged references. Fixture interactions do not
prove API behavior, permissions, or provider execution.
- UI changes to shared controls may affect pages outside the proposal
sandbox. Focused browser checks and the full CI matrix passed.

## Model Used

- OpenAI Codex, GPT-6 family. The exact runtime model ID and context
window are not exposed in this session. The model used reasoning, code
execution, browser inspection, and local tests. Earlier branch commits
were also AI-assisted in this Codex conversation.
