## Thinking Path > - Paperclip is the open source app people use to manage AI agents for work. > - Skills can track a branch in an authorized GitHub repository. > - Sources previously offered only a default-branch repair action. > - People need to select a listed branch or enter a branch that GitHub has not listed. > - The server must validate the selected ref with the caller's authorized connection. > - This pull request connects the approved branch picker to production APIs. > - Installed skills remain usable while the source changes its tracked ref. ## Linked Issues or Issue Description **Subsystem affected** Skills UI, shared API contracts, GitHub source services, and agent API discovery. **Problem or motivation** The default-branch repair action does not let people choose another branch. The settings service also validates the old ref when a caller supplies a new ref other than HEAD. A missing tracked branch can prevent connection repair even when the selected account has repository access. **Proposed solution** Load a bounded branch list with the authorized connection. Mark the default branch. Search listed branches or accept a typed ref. Validate the selected ref before saving. Keep the chosen value after a load error, invalid ref, or concurrent update. Save the selected connection and branch together during connection repair. **Alternatives considered** A default-branch button does not support a named branch. A text field alone does not help people find the repository default or available branches. **Roadmap alignment** This improves the existing Skills source manager. It does not add a new skill import system. **Additional context** Refs #16066 and #16256. This is the production implementation of the approved branch-selection Storybook journeys. ## What Changed - Add an authorized branch-list endpoint and shared response/query types. Register it in agent API discovery. - Validate the requested ref, including the returned commit SHA. Preserve source leases, revision checks, project ownership, skill identities, selections, and installed versions. - Add the searchable branch picker to Sources and connection repair. Allow typed refs during branch discovery and after discovery fails. - Keep save errors in the dialog. Retain the selected branch through a concurrent source update. - Use the production components and API client in Storybook. Add keyboard, touch, loading, retry, invalid-ref, connection-repair, and concurrent-update browser journeys. - Update product documentation and the feature/access maps. ## Verification - Red/green: two new database regressions fail against the previous service and pass against the implementation. - Linux database/service suite: 85 tests passed. This includes source visibility, human/agent authorization, selected connections, immutable versions, and invalid refs. - Rebased branch and review fixes: 94 focused UI, route, branch-validation, and fixture tests passed. Two conflict-message regressions and the stale-retry fixture regression fail before the fix and pass after it. - Storybook build passed. All 26 focused browser journeys passed. - Repository typecheck and build passed. Final UI typecheck passed after the review fixes. - The full local Vitest run was interrupted when the checkout and its dependencies disappeared. It reported missing working-directory/Postgres files and worker startup errors. Its two timed-out tests pass after the checkout was restored. The complete CI suite passed on the final head, `cf5d4c8f0a`: [CI run](https://github.com/paperclipai/paperclip/actions/runs/38571068332). One unchanged workspace timestamp test required a single rerun. Its release-minus-one-millisecond value can equal the original confirmation time. The rerun passed. - Live acceptance passed on implementation head `5dd935bf14` in an isolated macOS arm64 instance with Node 24.21.0 and an authorized private GitHub repository. The UI loaded the actual default branch, saved branch and selected connection together, and preserved the installed skill/version IDs after reload. An invalid typed ref retained the draft and showed the provider error. A valid typed HEAD ref then saved successfully. The owned runtime and database were stopped after the test. Focused unit, Linux database, and browser suites passed again after the error-handling review fixes. - Greptile reviewed final head `cf5d4c8f0a` at 5/5. Both review threads are resolved; the fresh review has no remaining findings. - Token gates and map/catalog checks passed. - Review entry points: `Skills / Project repository skills / 03 Branch selection components` and `04 Branch selection journeys`. Run `pnpm storybook` to inspect them. - Browser command: `pnpm exec playwright test --config tests/storybook-visual/playwright.config.ts tests/storybook-visual/skill-source-branch-selection.spec.ts tests/storybook-visual/project-repository-skills.spec.ts`. - Manual check: open an independent GitHub source, choose a new branch, select the default or type a ref, save, and reload. Try an invalid ref and confirm the selection remains in the dialog. For a project-bound source, change its ref in project settings. ## Risks - GitHub discovery is bounded to 100 listed branches. The default branch is always included. Typed refs remain available. - A source can change while the dialog is open. The API rejects a stale revision and the UI keeps the draft for retry. - A ref change schedules the existing refresh pipeline. Installed versions remain available until a successful refresh imports new content. - No database migration or credential storage change is required. Existing HEAD requests remain supported. ## Model Used OpenAI Codex, GPT-6 family. The serving model's exact identifier and context-window size are not exposed in this session. Used reasoning, repository tools, code execution, and browser tools. ## 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) - [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 - [x] I have either (a) linked existing issues with `Fixes: #` / `Closes #` / `Refs #` OR (b) described the issue in-PR following the relevant issue template - [x] I have not referenced internal/instance-local Paperclip issues or links (only public GitHub `#NNN` / `github.com/paperclipai/paperclip` URLs) - [x] My branch name describes the change (e.g. `docs/...`, `fix/...`) and contains no internal Paperclip ticket id or instance-derived details - [x] I have run 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 any 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: Paperclip <noreply@paperclip.ing>
Paperclip agent access map
This map accompanies the feature map. It records APIs, agent entry points, permission boundaries and verification for the same capability IDs. The shared contract defines the format and maintenance rules.
Browse access contracts
The same-named feature recipes define navigation and capability IDs. Run
node scripts/storybook-catalog.mjs for the generated
maps/generated/agent-access-map.md index, or browse the
published feature guide.
Add or update the affected companion; there is no central registration or count.
Existing baseline source references describe the original inspection, not current verification. Record new executed evidence in the PR, issue, or CI artifact with its revision and scope. Do not refresh unrelated headers as bookkeeping.
Using an entry
Read its Policy and Gaps before selecting an agent path. Native fallback, legacy
REST/CLI, stdio MCP and a personal assistant connection can have different
authority and availability. Use a real admitted production binding; a scenario
declaration is not an installed tool. A restricted entry records current
enforcement and leaves any unresolved delegation decision visible.
For API catalog disagreements, follow the route/service authorization and record
discovery drift. For not-applicable, retain the concrete exception and local
path. Split shared business operations from client-only presentation.
Use maintain-verification-skill to reconcile changed source and both maps.
Use verify-paperclip and existing API/runner/MCP fixtures to collect the
permitted-agent and denial evidence; report blocked/not-run coverage honestly.
Run node scripts/check-maps.mjs after editing. The structural check does not
certify permissions, API catalog coverage, tool admission or live behavior.
Native REST transport
The call_api parity change reconciles affected baselines against
58e16dbddfc9c8d0cf60867f9d9847f0feda055b and the changes in this PR. Ordinary
REST operations use the same route authorization as legacy agent REST. Dedicated
tools remain optional for those operations; protocol endpoints still need their
existing clients. Board-only routes remain restricted for agent identity.
Native search_api / call_api requires operator rollout admission, a running
authorized native run, current task assignment and execution-run binding, company
and budget authority, task privacy, and a permitted work mode. Ask and Plan retain
mutation restrictions, and runs retain their admitted JWT scope during restart
recovery even when task mode changes. A waiting
agent does not gain independent native control just because a REST route exists.
Credential-bearing replies, including company exports and their legacy alias, stay inline under a 10 MiB limit and use encrypted mutation receipts. Other saved API snapshots are limited to the issuing actor and responsible user, plus authorized administrators. Artifact uploads enforce the same access checks as downloads; private snapshots are excluded from company exports and public company logos. Explicit deliverables use the existing sharing path. Native event history, checkpoints and completion records omit API bodies while preserving receipt metadata and replay digests. Restored webhook secrets use the same encrypted receipt and inline response policy as newly created webhook secrets. Task image access requires the company boundary and the task permission; skill-test and low-trust agents do not need company-wide browsing authority. Completion replay applies the same idempotent projection to stored and expected payloads; the run-log guide describes its fields.
Sources: API client,
catalog,
native authority,
credential storage classification,
snapshot access,
and history redaction. The affected entries remain
baseline and source-only; this reconciliation does not certify every operation.
Targeted real-route proof lives in the
API integration suite,
including owned routines, skill tests, scoped secrets, proposals and private export replay.
