## 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.

Paperclip feature map
Start here when reproducing a user-facing bug, verifying a change, or deciding which surfaces a fix must cover. Each recipe describes what a person can do, where they can do it, the expected result, and the evidence needed to verify it. Product behavior is still governed by the implementation spec.
The sibling agent access map records APIs, agent entry points and permission boundaries for the same capability IDs. Follow the shared map contract when maintaining either map.
Browse features
Open the published Storybook guide for the assembled feature and capability index. The Markdown recipes in this directory are the authored source. Each has a same-named agent-access companion.
Run node scripts/storybook-catalog.mjs to generate local navigation in
maps/generated/feature-map.md, maps/generated/agent-access-map.md, and the
Storybook guide. A new recipe is discovered automatically; do not register it in
this README or maintain counts here.
Before driving a journey
- Use this checkout's isolated test drive for manual product checks. It creates a temporary instance and prints its URL and data directory. Do not guess that a server on port 3100 belongs to you.
- Record the commit, URL, company, login role, relevant experimental settings, adapter, runtime mode, and live versus simulated dependencies. Use disposable tasks and provider resources. A fresh test drive creates a company and CEO, but no task or first run.
- Use the current navigation and company prefix. Paths in recipes omit that prefix. Record whether the streamlined or production shell is selected; Agent Chat, chat connectors, and the combined Inbox/Tasks view have separate gates. A hidden surface is an unmet prerequisite, not a successful test.
- Run the smallest relevant test first. Vitest commands below run from the repository root after installing dependencies. Playwright recipes use their named configuration and its isolated environment, not an unrelated running instance. Reserve expensive runner/provider tests for the behavior at issue.
- Exercise the actual user action, inspect its result, reload, and verify the persisted state or continuation. Use read-only API checks to corroborate UI evidence; creating state through the API does not prove the creation UI.
For agent-driven acceptance work, start with the Paperclip verification skill for an isolated launch, ownership/readiness checks, browser driving, evidence, and cleanup. It uses this directory as its feature map. The existing dev-workspace run/verify skill and evaluation skill describe runtime ownership and evidence handling. Reuse them; this map introduces no environment launcher, credentials, scheduled job, or second test framework.
Evidence contract
Report each entry point as passed, failed, blocked (with its missing prerequisite), or not run. Include the feature filename and entry-point ID, commit/environment, user action, expected and observed result, command/exit code, and evidence links. Screenshots or traces should show both the action and the discriminating result. Include task/run/request IDs when relevant, without secrets.
A fix is verified across its affected surfaces only when each has evidence or an explicit reason it does not apply. Shared code alone does not prove parity. Keep product regressions visible; do not change the recipe to bless a failure. For Paperclip-assigned work, attach evidence through the artifact workflow.
Inventory and remaining depth
The generated maps/generated/coverage.json lists the current non-test TSX page
modules and the recipes that directly reference each one. An unreferenced module
is a documentation candidate, not proof that its feature is absent or untested.
Remaining workflow limits live in each recipe. Inventory and example associations
describe documentation scope, not runtime health.
Maintaining the reference
The map documents user journeys. It does not execute them automatically; generated inventories record documentation scope rather than live test health.
When maintaining a recipe, compare its entry points and expected results with
the current source. Check that linked tests still exercise the stated behavior
and that local references still exist. Keep the same-named agent access companion
and stable sub-feature IDs aligned when behavior or access changes. Source-only
access inventory remains distinct from live verification. Run
node scripts/check-maps.mjs after map edits for structural/reference checks;
follow the shared contract for the source and behavioral checks it cannot perform.
Each recipe starts with a small frontmatter navigation record, then an H1:
---
navigation: {"section":"Tasks and conversations","sectionOrder":20,"order":10}
---
The H1 supplies the feature title, and the first paragraph supplies its summary. Orders are local to the section; leave gaps for additions. Equal orders use the stable filename as a tie-breaker. Keep a section's name/order consistent across its recipes. A new feature or capability needs only its recipe and companion.
Optional ### Storybook verification guidance lives inside the recipe's Gotchas
section. Each level-four heading contains a backtick-quoted capability key and
has Scope (ui, cli, or browser),
Storybook, Production, and Sources fields. These are verification instructions
and intentional scope limits, not run results or a required story for every API.
The generated gap report combines this guidance with current story associations.
After frontmatter, each recipe starts with an H1 and a user-visible description, then exactly:
- Sub-features — stable backticked IDs and observable behavior/states.
- How to get to it (user POV) — one H3 backticked entry-point ID per surface.
- Driving it with — starts with
Preconditions:; repeat each entry-point H3, withAutomated:andManual:paragraphs. Name test scope and gaps honestly. - Gotchas — misleading look-alikes, feature gates, and invalid evidence.
New or updated entries follow
Poteto's feature-map examples.
Existing entries with a Driving it heading can adopt the named harness when
their recipes are updated. The original format was inspired by
Omnigent's feature map.
Paperclip's recipes and checks follow its own task model and test infrastructure.
