Agent skill
github-scanning
GitHub data collection patterns for workflow agents. Covers search query construction by intent, date range handling, repository scope narrowing, preferences.md integration, cross-repo intelligence, parallel stream collection model, and auto-recovery for empty results. Use when building agents that search GitHub for issues, PRs, discussions, releases, security alerts, or CI status.

GitHub Scanning
Search Query Patterns by Intent
Issues
| Intent | Query Pattern | Scope |
|---|---|---|
| Assigned to you | is:open assignee:USERNAME |
All repos |
| You were @mentioned | is:open mentions:USERNAME |
All repos |
| Authored by you | is:open author:USERNAME |
All repos |
| Specific repo | repo:owner/repo is:open |
Single repo |
| By keyword | {keyword} is:open |
All repos |
| Org-wide | org:ORGNAME is:open |
Org repos |
| Closed (for recap) | is:closed author:USERNAME |
All repos |
Pull Requests
| Intent | Query Pattern | Scope |
|---|---|---|
| Awaiting your review | review-requested:USERNAME state:open |
All repos |
| Your open PRs | author:USERNAME state:open |
All repos |
| Assigned to you | assignee:USERNAME state:open |
All repos |
| You reviewed, check for updates | reviewed-by:USERNAME state:open |
All repos |
| Specific PR | Fetch directly with owner, repo, number | Single repo |
| Org-wide | org:ORGNAME state:open |
Org repos |
Discussions
| Intent | Action |
|---|---|
| You're mentioned | Search with mentions:USERNAME |
| You're participating | Search discussions you've commented on |
| High activity | Filter for 10+ comments in last 24h |
| Linked to your issues | Scan description/comments for issue references |
Releases
- Use
github_list_releasesper repo - check for recent, draft, and pre-releases. - Cross-reference merged PRs against release notes to identify unreleased work.
- Compare issue milestones against release schedules to flag upcoming deadline items.
Security
- Dependabot alerts: critical and high severity across monitored repos.
- Security advisories affecting dependencies.
- Pending dependency update PRs from
dependabot[bot]orrenovate[bot].
CI/CD
- Fetch recent workflow runs - identify failing workflows, long jobs, and flaky tests.
- For failing workflows: note repo, workflow name, branch, failure reason, and link to run.
- Cross-reference user's open PRs against CI results.
Date Range Handling
Convert natural language to GitHub query qualifiers:
| User Says | GitHub Qualifier |
|---|---|
| "last week" | created:>YYYY-MM-DD (7 days ago) |
| "this month" | created:>YYYY-MM-01 |
| "today" | closed:YYYY-MM-DD |
| "this week" | closed:>YYYY-MM-DD (7 days ago) |
| "between X and Y" | created:X..Y |
| Not specified | Use search.default_window from preferences (default: updated:>YYYY-MM-DD 30 days) - mention this assumption |
| "for current month" (a11y tracker) | milestone:"{Month} {Year}" |
Scope Narrowing
Add qualifiers to narrow by scope when the user specifies one:
| Scope | Qualifier |
|---|---|
| Single repo | repo:owner/name |
| All org repos | org:orgname |
| All repos by user | user:username |
| Everything (default) | No qualifier - searches all accessible repos |
Preferences File Integration
Read .github/agents/preferences.md and apply these filters before and after searching:
repos.discovery- determines the default search scope (all / starred / owned / configured / workspace).repos.include- always include these repos even in restricted modes.repos.exclude- skip these repos in all searches.repos.overrides- per-repo settings:track.issues: false-> skip issue searches for this repotrack.pull_requests: false-> skip PR searches for this repotrack.discussions: false-> skip discussions for this repotrack.releases: false-> skip release checks for this repotrack.security: false-> skip security alerts for this repotrack.ci: false-> skip CI status for this repolabels.include/labels.exclude-> filter results by labelpaths-> only trigger for changes touching these file paths (for PRs/CI)assignees-> filter to specific assignees (empty = all)
search.default_window- default time range if the user doesn't specify one.briefing.sections- which sections to include in the daily briefing.accessibility_tracking- config for the a11y tracker (repos, labels, channels).
Cross-Repo Intelligence
When results arrive from different repos, look for and surface these patterns:
| Pattern | Action |
|---|---|
| Cross-repo references | When issue A contains owner/repo#N, fetch and surface item N |
| Shared label patterns | Group items in different repos tagged P0 together in triage |
| Related PRs in different repos | Flag: "This issue depends on PR #N in repo-B which is still open" |
| Merged PR not yet released | Note: "Your PR #N is merged but not in any release yet" |
| Issue with merged fix PR | Flag: "This may be resolved - PR #N that closes it was merged on {date}" |
| Branch naming patterns | Group PRs in different repos using the same branch naming convention |
Parallel Stream Collection Model
For agents that collect from multiple data streams, run independent streams simultaneously. Don't serialize operations with no dependencies.
Example: Daily Briefing - 3 Parallel Batches
Batch 1 - fully independent, run simultaneously:
- Issues (assigned, mentioned, authored)
- Pull requests (review-requested, authored)
- Releases & deployments
- Accessibility updates
Batch 2 - run after Batch 1 (CI needs PR list from Batch 1):
- GitHub Discussions
- CI/CD health (cross-references PR list)
- Security alerts
Batch 3 - can overlap with Batch 2:
- Project board status
- Recently closed/merged work
Example: Analytics - 2 Parallel Batches
Batch 1 - collection (all independent):
- Closed/merged PRs in period
- Opened issues in period
- CI workflow runs in period
- Security alerts in period
Batch 2 - analysis (depends on Batch 1 data):
- Health score computation
- Velocity metrics calculation
- Bottleneck detection
Announcement Template for Parallel Work
Running {N} searches in parallel... ({scope})
Batch 1 complete - {X} items found
Running {N} additional searches...
Batch 2 complete - {Y} items found
Scoring and prioritizing...
Done - {Z} items need action, {W} to monitor
Auto-Recovery for Empty Results
If a search returns 0 results:
- Automatically broaden: remove date filter, expand scope to
all, or remove label filters. - Tell the user exactly what changed: "No results in last 7 days - broadened to last 30 days and found 3 items."
- Never return 0 results without trying at least one broader query first.
Recovery cascade:
- First try: Remove date qualifier
- Second try: Expand scope (add org: or remove repo: qualifier)
- Third try: Remove label filters
- Report 0 results only if all three attempts return nothing
Pagination
- Paginate large result sets in batches of 10.
- Ask before loading more: "Showing 10 of 47. Load more?"
- Never silently truncate results - always disclose the total count.
Result Deduplication
When the same item appears in multiple searches (e.g., an issue you're both assigned to AND mentioned in):
- Show it once, with all context combined.
- In the Signal column, combine signals: "Assigned, @mentioned".
- In priority calculations, apply the highest-scoring signal, not additive.
Rate Limiting
- If rate-limited (403/429), tell the user the reset time in one sentence.
- Do not retry the same query - wait if reset is <60 seconds; otherwise report and move on.
- For multi-stream collection, skip rate-limited streams and complete them in a follow-up.
