Why

Cloning from GitHub requires the exact owner/repo. If you type part of a name, such as sleepy, nothing is listed, and pressing Enter fails with "Repository lookup failed". In practice you leave the app, find the repository on github.com, copy its full name and paste it back. This was requested in #8654.

GitHub already has a search that knows which repositories you can see, including private ones. The dialog now passes what you type to that search and lets you pick a result.

What Changed

In the GitHub step of Add Project → Clone, typing three or more characters shows matching repositories after a short pause. Your own repositories come first, followed by matches from all of GitHub. Picking one continues into the existing clone flow. Typing an exact owner/repo and pressing Enter works as before, and the other providers are unchanged.

  • One new RPC, sourceControl.searchRepositories. It uses the same permission as the existing repository lookup, and returns the name and description of each match.
  • GitHub only, through the gh CLI the connector already uses. No new auth, tokens or GraphQL. Search is an optional provider capability, so GitLab, Forgejo, Bitbucket and Azure DevOps need no changes.
  • Two searches per pause, merged. <query> user:@me (top 5) runs alongside <query> (top 20), with duplicates removed. A single global search ranks by popularity, so personal repositories drop out: sleepy alone doesn't return markomitranic/sleepytime-youtube in its top 20, and GitHub rejects combining user:@me with OR.
  • Web and mobile. The command palette and the mobile Add Project screen both show the results list. Search starts at 3 characters, after a 500 ms pause.
  • Docs. One sentence in docs/user/source-control.md.
palette / mobile ──(debounced query)──▶ sourceControl.searchRepositories
                                            │
                                GitHub provider (optional capability)
                                            │
                        gh search repos "<q> user:@me"  ─┐ merged, own first,
                        gh search repos "<q>"           ─┘ duplicates removed
                                            │
         selected result ──▶ existing sourceControl.lookupRepository ──▶ clone

Notes for review

  • Rate limit. GitHub's search API allows 30 requests per minute, and each pause uses two. With the 3-character minimum and 500 ms debounce that's modest. If the limit is hit, the list shows GitHub's error and exact owner/repo lookup still works.
  • Why this is smaller than fix(github): search repositories by name #8340. That PR was closed over the cost of maintaining GraphQL and auth. This version has no GraphQL, no rate-limit budget code and no new credentials. It's two gh search repos calls behind the existing CLI wrapper.
  • Older servers. A new client talking to an older server shows the error in the empty state. Exact lookup still works there.
  • Not in this PR. Repositories from organizations you belong to only appear in the global part of the results, not in the first group.

UI Changes

Before: typing sleepy lists nothing, and Enter fails:

Before: no results for sleepy

Before: repository lookup failed

After: searching, then results with the account's own repository first:

After: searching GitHub

After: results for sleepy

Picking a result goes on to the clone destination step:

After: clone destination

🤖 Generated with Claude Code

The GitHub clone step only accepted an exact owner/repo. Typing part of a
name now searches GitHub: the signed-in account's matches first, then all
of GitHub, and picking a result continues into the existing clone flow.

Merge Risk: 🔵 Low · up to ff0e4

Editing a GitHub search can briefly leave results for the old query selectable, potentially opening the wrong repository’s clone flow. The issue is brief and recoverable, so merge risk is low.

Security Architecture Review

Security architecture risk: 🔵 Low · up to ff0e4

Search broadens discovery of repositories visible to the server’s GitHub account, including private repository names and descriptions. Existing read permissions still gate discovery, and cloning remains separately permissioned. Shared-account access and deployment compatibility are not fully established.

Retained concerns
No architecture-level concerns identified.

Security review details

Security Blast Radius

  • inferred — A caller with the environment’s read scope gains searchable repository-name and description discovery under the GitHub identity used by that server, potentially including private repositories visible to that identity. This is broader discovery than supplying an exact repository identifier, but does not grant cloning authority through the search endpoint.

Security Findings and Attack Paths

  • observed — The attacker-controlled query occupies one argument after the CLI’s -- separator. The endpoint does not accept an executable, argument array, environment, token, or working directory. These controls constrain the new entrypoint to repository discovery rather than arbitrary CLI execution.

Trust Boundaries and Controls

  • observed — Environment-session authorization and GitHub credential authority remain separate boundaries. The existing executor uses a pinned credential when supplied and rejects commands that do not target its verified host; otherwise it uses the existing CLI credential path. This executor behavior predates the PR, and per-client credential provisioning was not established.

Resilience and Maintainability Implications

  • observed — Search result selection remains a transient client step followed by repository lookup and a separate destination or confirmation step. Previous debounced results can remain selectable after an input edit, but the inspected selection path does not automatically clone or bypass the server’s operate-scope gate.

Hardening Proposals

  • proposed — For environments shared by independently trusted users, explicitly define whether read permission includes discovering private repository metadata under the server’s GitHub account. If narrower visibility is required, bind discovery to an appropriate verified identity rather than treating environment read access as sufficient.
  • proposed — Consider a server-side search-specific request budget for shared environments. Client debounce does not constrain direct RPC callers, and search commands do not enter the existing CLI budget branch used for repository and pull-request reads. Existing process permits remain useful containment, but do not establish a search request-rate policy.

Would it be possible to implement the optional search capability for GitLab as well, either in this PR or as a follow-up? The GitLab lookup is currently stricter than GitHub's, so search would help more there.

Why GitLab needs it more: GitLabCli.getRepositoryCloneUrls calls glab api projects/<input>, which only accepts the exact full path. With gh repo view, a bare name resolves to your own account. With GitLab, project fails, even though user/project exists and glab repo view project finds it. Group projects are harder still, because a bare name can never resolve to them: app means group/app or group/subgroup/app (nested groups are common on GitLab). Today the user gets the generic "lookupRepository failed for gitlab: The source control operation could not be completed."

One call covers personal and group projects:

glab api "projects?search=<q>&membership=true&simple=true&per_page=20&order_by=last_activity_at"

Verified on gitlab.com against a real account with ~80 projects across a personal namespace and nested groups. The paths below are renamed to generic placeholders:

query results
project user/project
app group/app, group/subgroup/app

Notes for the implementation:

  • membership=true scopes results to projects the user can access, including private ones. That fits the "your repositories first" ordering without a second global query. Unlike GitHub, a global GitLab search mostly returns noise.
  • GitLab returns [] for queries under 3 characters, so the 3-character threshold in this PR fits GitLab as well.
  • Adding search_namespaces=true lets queries like group/subgroup match on the group path as well as the project name.
  • It goes through the same glab CLI and host selection the GitLab connector already uses, so it needs no new auth.

@valshin thanks, that's a great write-up, and the membership=true query looks like the right fit for GitLab. I'd rather keep this PR to GitHub so it stays small and reviewable. Also i have no way to test GitLab so I'd be doing it blindly. Search is already an optional provider capability on the server, so a follow-up only needs searchRepositories in the GitLab provider and the github-only check in the web and mobile clone step widened. Happy to review it if you open one.

This comment is posted by Julius' dot

This adds a repository-search picker to the existing clone flow, which needs prior direction and scope approval. The linked #8654 asks for an Ideas discussion, and #8340 was declined; neither approves this new workflow. The simpler CLI approach and supplied demo don't replace that approval. Closing for now: please discuss this approach with maintainers, link their explicit approval, and request reconsideration. The friction of finding a repository's exact name is still a useful problem to raise.
