## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agent work is issue-centered, and reviewers often need to inspect
files, artifacts, and path references produced during that work.
> - Before this branch, workspace-relative paths and artifact file
references were not first-class inspectable objects in the board UI.
> - Safe file viewing needs shared resource contracts, server-side
workspace boundary checks, and UI that opens files without exposing
arbitrary host paths.
> - The workspace file viewer branch needed to stay as one active PR and
be rebased onto current `paperclipai/paperclip:master` for review.
> - This pull request adds the workspace file resource API, issue-page
file viewer and browser, markdown file-reference links, and artifact
file chips.
> - The benefit is that board users can inspect relevant files from
issue context while preserving workspace boundaries and auditability.
## Linked Issues or Issue Description
No public GitHub issue exists for this branch. Internal Paperclip
issues: `PAP-1953`, `PAP-10539`, `PAP-10733`.
Problem / motivation:
- Board users need to open workspace-relative files mentioned by agents
or attached as work-product metadata without switching to a terminal.
- The UI needs to support both direct file-path opening and workspace
browsing/searching from an issue page.
- The server must enforce company access, workspace boundaries, size
limits, rate limits, and safe audit logging.
Related PR:
- Prior closed attempt: #4442
- Single active PR for this branch: #7681
## What Changed
- Added shared workspace file resource types, validators, and
workspace-file `resourceRef` metadata validation for work products.
- Added server routes/services for resolving, listing, and previewing
workspace-relative files with access checks, scan caps, list-specific
limits, and audit logging.
- Added the issue file viewer provider, sheet, workspace browser,
command-palette action, markdown workspace-file autolinks, and artifact
file chips.
- Updated issue workspace UI and stories/tests for file browsing and
workspace file opening.
- Rebased the branch onto current `paperclipai/paperclip:master` and
updated the existing single PR branch.
- Addressed current-head Greptile follow-ups by applying `offset`
consistently across search/recent/changed file listings, restoring
stopped-service port ownership checks before auto-port reuse, and
stabilizing the workspace browser pagination test.
## Verification
Current local verification after rebase to `public/master`:
- `pnpm exec vitest run packages/shared/src/work-product.test.ts
server/src/__tests__/file-resources.test.ts
server/src/__tests__/instance-settings-routes.test.ts
server/src/__tests__/instance-settings-service.test.ts
server/src/__tests__/workspace-runtime.test.ts
ui/src/components/FileViewerSheet.test.tsx
ui/src/components/FileViewerSheet.copy.test.tsx
ui/src/components/WorkspaceFileBrowser.test.tsx
ui/src/components/WorkspaceFileMarkdownBody.test.tsx
ui/src/context/FileViewerContext.test.ts
ui/src/lib/remark-workspace-file-refs.test.ts
ui/src/lib/workspace-file-parser.test.ts
ui/src/components/IssueWorkspaceCard.test.tsx` - 13 files passed, 197
tests passed.
- `pnpm -r --filter @paperclipai/shared --filter @paperclipai/server
--filter @paperclipai/ui typecheck` - passed.
- `pnpm exec vitest run ui/src/components/WorkspaceFileBrowser.test.tsx`
- 1 file passed, 25 tests passed.
- `pnpm exec vitest run server/src/__tests__/file-resources.test.ts
server/src/__tests__/workspace-runtime.test.ts` - 2 files passed, 90
tests passed.
- `pnpm -r --filter @paperclipai/server typecheck` - passed.
- Confirmed branch is `0` behind and `46` ahead of current
`public/master` after rebase and follow-up commits.
- Confirmed the PR diff does not include `pnpm-lock.yaml`.
- Confirmed the PR diff does not include `.github/workflows` changes.
- Searched GitHub for duplicate or related workspace file viewer
PRs/issues; #4442 is the prior closed attempt and this PR is the single
active PR for the branch.
- No screenshots were committed; the task explicitly asked not to add
design screenshots or images unless they were part of the work.
Current remote verification on head
`a698a7bc10137baf7d25bd5722e1d6e0343387c1`:
- Greptile Review - success, 64 files reviewed, 0 comments added, no
unresolved Greptile review threads.
- PR workflow `verify` - success.
- Typecheck + Release Registry, General tests, workspace test shards,
serialized server suites, Build, Canary Dry Run, e2e, Socket, and Snyk -
success.
- `security-review` - neutral, with output saying a draft advisory was
filed for maintainer review and is not a merge block.
- `commitperclip PR Review / review` - cancelled after the security gate
detected flags and timed out while creating/reviewing the advisory. I
reran it once and it cancelled the same way; no actionable code/test
failure was exposed in the job logs.
## Risks
- This is a broad UI/server feature PR, so review needs to pay attention
to route authorization, workspace boundary handling, and markdown
autolink false positives.
- Workspace browsing intentionally caps list results and scan depth;
very large workspaces may require users to refine search terms.
- Remote workspace preview remains unavailable until remote file-access
support is implemented.
- The neutral commitperclip security-review advisory needs maintainer
review, but the check output says it is not a merge block.
> For core feature work, check [`ROADMAP.md`](ROADMAP.md) first and
discuss it in `#dev` before opening the PR. Feature PRs that overlap
with planned core work may need to be redirected - check the roadmap
first. See `CONTRIBUTING.md`.
## Model Used
- OpenAI Codex, GPT-5 coding agent in a Paperclip/Codex local tool-use
environment, medium reasoning, with shell/GitHub CLI tool use for branch
inspection, verification, rebase, PR update, Greptile review, and CI
inspection.
