Conversation
- Create new module `lib/gh_prs_matching.js` as single source of truth for PR fetching - Replace three hand-rolled fetchers with declarative predicate specs - Each agent's `loop_fetch_work` becomes thin shim reading spec, calling fetcher - Move shared boilerplate (auth, repo lookup, rate-limit, base query) to one place - Per-agent behavior remains byte-identical to current implementation - Add tests covering fixer, merger, and pr-reviewer predicate matching - Tests use PATH-shim `gh` fixture script, no live GitHub calls Patch generated by openrouter/free via OpenRouter.

Scope PR search to the resolved repository.
repoResolve() resolves a target repository, but buildQueryFromSpec(spec) does not use it, so the search can return pull requests from any repository visible to the token. Add the resolved repository as repo:OWNER/REPO or otherwise enforce the repository scope before executing the query.

Octokit search issues PRs endpoint /search/issues q issue_pulls response items data
💡 Result:
The GitHub REST API endpoint for searching issues and pull requests is GET /search/issues [1][2]. When using Octokit (e.g., in JavaScript/TypeScript), this endpoint is accessed via octokit.rest.search.issuesAndPullRequests({ q }) [1][3]. Response Data Structure: The response from this endpoint is a JSON object [4]. The core search results are contained within the items array [5][6]. Important top-level fields in the response include: total_count (integer): The total number of issues and pull requests matching your search query [5]. incomplete_results (boolean): Indicates whether the search results are incomplete (e.g., due to a timeout or hitting search limits). items (array): An array of issue or pull request objects that match the criteria [5][6]. Each object within the items array typically contains metadata about the issue or pull request, such as the url, html_url, number, title, user, state, created_at, updated_at, body, and labels [4]. Important Implementation Notes: 1. Deprecation and Changes: The endpoint/method is currently undergoing changes regarding how it handles issues versus pull requests [7]. For GitHub Apps, it is mandatory to specify is:issue or is:pull-request in your query string; otherwise, you will receive an HTTP 422 error [2][3]. 2. Pagination: By default, the API returns up to 30 items per page, with a maximum of 100 [1][6]. You can use the per_page and page parameters to control this [1][3]. For automated pagination (fetching all results across pages), the Octokit paginate method is recommended [6][8]. 3. Text Match Metadata: If you require highlighted search results (showing where the keyword matches in the title or body), you must request the text-match media type in your headers [2][3]. 4. Advanced Search: Some documentation references an advanced_search parameter [9][7], though users should monitor official GitHub REST API release notes for the most current requirements regarding this feature, as the search infrastructure has been evolving [7].

Do not force an incompatible state or default mergeability to false.
When require_state is "closed", the query contains both is:open and state:closed. It cannot match a closed PR. When a spec omits require_mergeable, undefined !== null is true, so the query adds mergeable:false. Derive the default state only when the predicate is absent, and use a nullish check for optional mergeability.
Proposed fix
-function buildQueryFromSpec(spec) {
- let query = 'is:pr is:open';
+function buildQueryFromSpec(spec) {
+ let query = `is:pr state:${spec.require_state ?? 'open'}`;
@@
- if (spec.require_state) {

GitHub issues search qualifiers threads approval CI_STATUS status mergeable head_sha documentation
💡 Result:
In GitHub, search qualifiers are used to narrow down search results for issues and pull requests [1][2]. It is important to distinguish between native GitHub search qualifiers and terms used in the GitHub API or third-party tools, as terms like CI_STATUS or mergeable are not standard top-level search qualifiers [1][3]. Official GitHub Search Qualifiers Native search qualifiers for issues and pull requests include standard filters such as: - is: (e.g., is:pr, is:open, is:closed) [1][3] - type: (e.g., type:pr, type:issue) [1] - author:, assignee:, label:, milestone:, mentions:, linked:, project: [1][3] Terms often confused with native search qualifiers: - Mergeable: This is not a native search qualifier (e.g., you cannot use mergeable:true in the search bar) [1]. However, the concept of mergeability is exposed via the GitHub REST API as a property of a pull request [4]. - CI_STATUS / Checks: While you cannot use CI_STATUS as a search qualifier, the GitHub CLI (gh) allows filtering by check status using --checks (e.g., pending, success, failure) [5]. - Approval / Review Status: You cannot use a direct approval qualifier in the search bar [1]. In the GitHub CLI, you can use the --review filter (e.g., approved, changes_requested) [5]. - head_sha / Expected_head_sha: These are concepts related to the GitHub REST API, specifically used when interacting with pull request endpoints to ensure synchronization during merge operations [4]. If you are building automation or workflows, note that these terms are often found in API responses or third-party GitHub Actions (e.g., such as those checking PR status) rather than in the platform's native global search input [4][6]. Use the GitHub REST API or GitHub CLI flags to perform these advanced status-based queries [4][5].

site:docs.github.com GitHub pull requests search qualifiers mergeable threads status-checks CI run status head_sha
💡 Result:
GitHub provides specific qualifiers for searching and filtering pull requests based on their status, mergeability, and commit information [1][2]. Note that some attributes, such as mergeable and head_sha, are primarily exposed through the GitHub REST API rather than as direct search qualifiers in the web interface's query bar [3][4]. Key qualifiers and attributes include: Status and CI Run Status - status:success, status:failure, status:pending: Use these qualifiers in the search bar to filter pull requests by the status of their associated checks [2]. - Required Status Checks: These are enforced by repository protection rules. GitHub tracks whether required checks have passed against the latest commit SHA [5]. If a test merge commit is involved, the status check may apply to the merge commit or the head commit itself [5]. Mergeability - is:merged, is:unmerged: These qualifiers filter pull requests by their current merge state [1][2]. - mergeable (API attribute): This attribute is returned by the Pull Request API endpoint [3]. It indicates whether a pull request can be automatically merged. A value of true, false, or null is returned; null indicates that GitHub is still calculating mergeability in the background [3]. Commit-related Qualifiers and Attributes - head:BRANCH_NAME: This qualifier filters pull requests based on the source (head) branch name [1]. - base:BRANCH_NAME: This qualifier filters pull requests based on the target (base) branch name [1]. - head_sha (API attribute): When interacting with the API, the head SHA represents the most recent commit on the pull request's branch [3]. You can specify expected_head_sha when performing operations (like merging) to ensure you are acting on the correct commit version [3]. For advanced filtering, you can combine these in the GitHub search bar or via the GitHub CLI using the --search flag [2]. When using the GitHub Search API, ensure you include is:pr to limit results to pull requests [4].

"CI_Status" GitHub search issues pull requests
💡 Result:
To search for pull requests on GitHub based on their CI (commit) status, you can use the status qualifier in the search bar or via the GitHub CLI [1][2][3]. This functionality is designed to filter pull requests based on the combined status reported by the Status API or integrated CI services [1][3]. Supported status qualifiers include [2][3]: - status:success: Matches pull requests where all status checks have passed [2][3]. - status:failure: Matches pull requests that have at least one status in the failure or error state [2][3]. - status:pending: Matches pull requests that have no statuses or at least one status in the pending state [2][3]. These qualifiers are specifically used for filtering pull requests [2][3]. Note that while GitHub Projects also utilize a status field (often for Kanban-style tracking), this is a custom field specific to the project and is distinct from the commit status API used for CI checks [4]. You can combine these with other search filters (e.g., is:open, author:username, etc.) to refine your results [1][2]. For example, searching for is:open status:failure will return all open pull requests that currently have a failed CI status [1][2].

GitHub REST API search Pull Requests response fields mergeable review_requested head_sha
💡 Result:
In the GitHub REST API, the mergeable, review_requested, and head_sha fields are handled differently depending on whether you are using the Search API or the Pulls API. 1. Pulls API (GET /repos/{owner}/{repo}/pulls/{pull_number}) This endpoint returns the full pull request object, which includes the following: - mergeable: A boolean indicating whether the pull request can be merged [1]. Note that this field is computed lazily; the first request may return null if GitHub is still performing the test-merge [1][2][3]. If it remains null, it is recommended to treat it as unknown [1]. - head: An object containing the pull request's head information, which includes the sha field (the head_sha) [1]. - The API does not have a single review_requested field. Instead, it provides the requested_reviewers (array of users) and requested_teams (array of teams) fields to show pending review requests [4][5][1]. 2. Search API (GET /search/issues) The Search API is designed to return a condensed list of issues and pull requests to optimize performance [6]. - It does not include computed fields like mergeable in the response [7]. - It does not return the full head object or head_sha [7]. - Search results for pull requests return a specific schema that focuses on metadata (e.g., url, html_url, merged_at, draft) [7]. If you need the mergeable status or specific commit SHA details, you must use the Pulls API endpoint for the individual pull request rather than relying on the Search API [7][1].

Fetch PR details before filtering required-thread, review, CI, and mergeability predicates.
threads, review, CI_Status, and boolean mergeable are not supported issue/pull-request search qualifiers. head_sha is also not available from the search response, so ci_status currently returns PASSING whenever head_sha exists instead of relying on CI status. Use supported qualifiers such as status:success, then fetch the full Pull Request/GraphQL details and apply the remaining predicates separately.
