## 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. ## Checklist - [x] I have included a thinking path that traces from project context to this change - [x] I have specified the model used (with version and capability details available in this session) - [x] I have checked ROADMAP.md and confirmed this PR does not duplicate planned core work - [x] I have searched GitHub for duplicate or related PRs and linked them above where applicable - [x] I have either linked existing issues or described the issue in-PR following the relevant issue template - [x] I have not referenced internal or instance-local Paperclip issues or links - [x] My branch name describes the change and contains no internal ticket id - [x] I have run focused tests locally and they pass - [x] I have added or updated tests where applicable - [x] I have updated relevant documentation to reflect my changes - [x] I have considered and documented risks above - [x] All Paperclip CI gates are green - [x] Greptile is 5/5 with no open P2s, recommendations, or follow-ups - [x] I will address all Greptile and reviewer comments before requesting merge --------- Co-authored-by: Scott Tong <scott@scotts-mbp-m5-max.local> Co-authored-by: Paperclip <noreply@paperclip.ing>
Storybook Visual Baselines
The visual suite compares built Storybook stories against PNG snapshots stored
outside git. The checked-in manifest at baseline-manifest.json pins the
immutable archive URL, SHA-256, byte size, snapshot count, and capture
environment.
Commands
pnpm storybook-visual:baseline download
pnpm storybook-visual:baseline verify
pnpm test:storybook-visual
pnpm test:storybook-visual:update
download fetches the archive, verifies its SHA-256 and byte size, unpacks it to
tests/storybook-visual/.snapshots/, and checks the PNG count. The same snapshot
directory can be overridden with STORYBOOK_VISUAL_SNAPSHOT_DIR.
Known Limitation: Linux Baselines
Storybook visual baselines are platform-locked. The checked-in manifest records
the capture environment as ubuntu-24.04, and Playwright compares screenshots
with maxDiffPixels: 0. Pixel-exact results are only meaningful when local runs
use the same Linux/Ubuntu capture platform as the baseline.
macOS, Windows, and other non-matching local environments can produce
false-positive diffs from font rasterization and subpixel rendering differences.
Use the Storybook Visual GitHub Actions workflow on ubuntu-latest as the
source of truth for cross-platform review, or run the suite locally in a matching
Linux environment before accepting or updating baselines.
CI and Review Artifacts
Storybook visual tests are opt-in while the suite stabilizes. Add the
storybook-visual label to a pull request, or run the Storybook Visual
workflow manually, to download the pinned baseline, build Storybook, and run the
Playwright visual suite on GitHub Actions.
The workflow uploads tests/storybook-visual/playwright-report/ and
tests/storybook-visual/test-results/ as a storybook-visual-report-* artifact
on every run. When screenshots differ, Playwright writes the actual, expected,
and diff PNGs into test-results, so reviewers can inspect the failure without
rerunning the suite locally.
Normal PR visual runs use repository read-only permissions and never upload or
modify baseline objects. To review intentional visual changes before updating
baseline-manifest.json, run the workflow manually with update_snapshots
enabled. That produces a storybook-visual-baseline-review-* artifact containing
the packed candidate snapshot archive for review. Publishing that bundle to the
baseline bucket still requires the explicit maintainer upload command below.
Updating Baselines
- Run
pnpm test:storybook-visual:updateafter reviewing intentional visual diffs. - Run
pnpm storybook-visual:baseline packto createtests/storybook-visual/baseline-review/snapshots.tgz. - Upload the archive from a trusted maintainer environment with
STORYBOOK_VISUAL_S3_URI=s3://bucket/baselines/storybook-visual/<sha>/snapshots.tgz pnpm storybook-visual:baseline upload. - Copy the printed
snapshotCountandarchivefields intobaseline-manifest.json.
Generated snapshots, review bundles, Playwright reports, and downloaded caches are ignored by git.
