Summary

The uiGetBranches function only fetched the first 100 branches without pagination, unlike uiGetAssignees and uiGetMilestones. This causes incomplete data for repositories with >100 branches.

Why

Addresses feedback from #1974 (#1974 (comment))

What changed

  • Added pagination loop in uiGetBranches following the pattern from uiGetAssignees and uiGetMilestones
  • Changed error handling to use utils.NewToolResultErrorFromErr() for consistency
  • Removed unnecessary manual response body handling (already covered by ghErrors.NewGitHubAPIErrorResponse())

MCP impact

  • No tool or API changes
  • Tool schema or behavior changed
    Tool now returns complete branch list instead of truncating at 100 branches. No schema changes.
  • New tool added

Prompts tested (tool changes only)

  • N/A (behavioral fix, no new functionality)

Security / limits

  • No security or limits impact
  • Auth / permissions considered
  • Data exposure, filtering, or token/size limits considered

Tool renaming

  • I am renaming tools as part of this PR (e.g. a part of a consolidation effort)
    • I have added the new tool aliases in deprecated_tool_aliases.go
  • I am not renaming tools as part of this PR

Lint & tests

  • Linted locally with ./script/lint
  • Tested locally with ./script/test

Docs

  • Not needed
  • Updated (README / docs / examples)

Pull request overview

This pull request fixes incomplete data fetching in the uiGetBranches function by implementing pagination. Previously, the function only returned the first 100 branches, which would truncate results for repositories with more than 100 branches. The changes align the implementation with the established pattern used in uiGetAssignees and uiGetMilestones.

Changes:

  • Added pagination loop to fetch all branches instead of just the first page
  • Updated error handling to use utils.NewToolResultErrorFromErr() for consistency
  • Removed unnecessary manual response body handling that duplicated work done by ghErrors.NewGitHubAPIErrorResponse()

* update to new insiders feature flag func

* ensure transient state is reset on successive tool calls

* Mark ui_get as app-only visibility

ui_get backs only the MCP App views and has no business in the agent's
tool list. Per the MCP Apps 2026-01-26 spec, omitting _meta.ui.visibility
defaults to ["model","app"], which exposes the tool to the model. Declare
visibility ["app"] so the host hides it from tools/list while the views can
still invoke it via tools/call.

* Update ui_get toolsnap for app-only visibility

Regenerated via UPDATE_TOOLSNAPS to capture the new _meta.ui.visibility.

* Assert ui_get declares app-only visibility

Locks in the _meta.ui.visibility ["app"] contract so a future edit can't
silently re-expose the UI data tool to the model.

Co-authored-by: Copilot <223556219+Copilot@users.noreply.github.com>

* Add ui_get to insiders feature docs

Regenerated docs/feature-flags.md and docs/insiders-features.md to include
the ui_get tool entry.

* Address ui_get review feedback

- Paginate the labels GraphQL query (cursor-based) so repos with more than
  100 labels return a complete list instead of silently truncating.
- Emit an empty due_on for milestones without a due date instead of
  formatting the zero time as "0001-01-01".
- Use NewGitHubAPIErrorResponse in uiGetIssueTypes to preserve GitHub
  response context, matching the other REST-backed methods.
- Extend tests to cover the labels (GraphQL), milestones (including the
  no-due-date case) and issue_types methods, plus the issue_types error path.

* Fix repo reset and stale base-branch in MCP App views

- Re-initialize selectedRepo from toolInput inside the reset-on-invocation
  effect instead of a separate effect. The two effects both depended on
  toolInput and ran in declaration order, so the reset wiped the just-
  initialized repo and the picker never reflected the invocation's owner/repo.
- Set the default base branch with a functional update in pr-write so a base
  prefilled from toolInput.base (or chosen by the user) isn't overwritten by
  a stale baseBranch value captured before the branches request resolved.

* Potential fix for pull request finding

Co-authored-by: Copilot Autofix powered by AI <175728472+Copilot@users.noreply.github.com>

* Fix issue-write repo owner mapping and clear stale UI state on reset

- issue-write: derive owner/name from full_name since search_repositories
  minimal output omits the owner object (mirrors pr-write)
- pr-write/issue-write: clear available branch/label/assignee/milestone/type
  lists and filters in the toolInput reset effect so prefill effects can't
  match against the previous repo's stale data

* Merge remote-tracking branch 'origin/main' into mcp-ui-apps-advanced

* feat: add pull request editing functionality with reviewers support

* feat: implement interactive form handling for issue and pull request creation and updates

* Close response body per page in ui_get pagination loops

Avoids leaking HTTP connections when paging through assignees,
milestones, branches, collaborators, and teams.

* Cache pr-edit.html in build-ui action

The build-ui cache only saved get-me/issue-write/pr-write HTML, so once a
cache entry was stored it restored an incomplete ui_dist on later runs and
skipped the rebuild, leaving pr-edit.html absent and panicking the tests.
Add pr-edit.html to the cached paths and bump the cache key to v2 to evict
the incomplete entries.
