Summary

  • collect repository Actions default workflow permission settings for repositories with active workflows
  • parse workflow and job permissions declarations and calculate effective GITHUB_TOKEN permissions per workflow job
  • add OIDC/token-permission saved searches, documentation, and tests

Testing

  • uv run pytest tests/test_workflow_model.py tests/test_workflow_resources.py tests/test_repository_rulesets.py
  • uv run ruff check src/openhound_github/models/workflow.py src/openhound_github/models/workflow_job.py tests/test_workflow_model.py tests/test_workflow_resources.py tests/test_repository_rulesets.py

Notes

Summary by CodeRabbit

  • New Features

    • Added workflow-job visibility into runner eligibility, normalized runner selectors, and effective GITHUB_TOKEN permissions.
    • Added repository workflow security settings and workflow-to-runner schedulability relationships.
    • Added saved searches for OIDC permissions and usage indicators, self-hosted runner exposure, and broad token write access.

Walkthrough

The change adds effective GITHUB_TOKEN permission modeling, static self-hosted runner schedulability, GH_RunsOn relationships, repository policy collection, deployment metadata, security saved searches, and related graph documentation.

Changes

Workflow security and runner analysis

Layer / File(s) Summary
Permission and selector resolution
src/openhound_github/models/workflow.py, src/openhound_github/models/workflow_job.py, src/openhound_github/models/repository.py, src/openhound_github/lookup.py, src/openhound_github/resources/..., src/openhound_github/source.py, tests/test_workflow_model.py, tests/test_workflow_resources.py, tests/test_repository_rulesets.py
Workflow and job models normalize runs-on and permission declarations. They calculate effective token permissions from repository, workflow, and job settings. Repository workflow permissions are fetched and cached.
Static runner matching and GH_RunsOn edges
src/openhound_github/lookup.py, src/openhound_github/models/workflow_job.py, src/openhound_github/models/runner.py, src/openhound_github/kinds/edges.py, extension/schema.json, src/openhound_github/main.py, src/openhound_github/transforms.py, tests/test_runner_models.py, tests/test_workflow_model.py
Runner lookup matches static labels and groups across repository, organization, and enterprise runners. Workflow jobs emit non-traversable GH_RunsOn edges for eligible runners.
Deployment metadata propagation
src/openhound_github/source.py, src/openhound_github/resources/organization.py
Source initialization detects deployment type and GHES version. The metadata propagates to source and organization contexts.
Security searches and graph documentation
extension/saved_searches/*, descriptions/edges/*, descriptions/nodes/*
Added saved searches for OIDC permissions, self-hosted OIDC jobs, broad token writes, and observed OIDC authentication steps. Documented permission fields and GH_RunsOn schedulability semantics.

Priority: ➖ Normal — Schedule the effective GitHub Actions permission change because it spans workflow modeling, runner resolution, OIDC security searches, and repository metadata.

Estimated code review effort: 4 (Complex) | ~45 minutes

Merge Risk: 🔵 Low · up to 13b10

Workflow permission and runner analysis is expanded, but empty workflow collections may log errors and some dynamic runner expressions may be reported as static. These bounded analysis-accuracy issues should be addressed before relying on the new results for security decisions.

Add the name and path columns to the workflows stub.

GithubLookup.workflow selects name and filters on path, but the stub declares neither column. The lookup can fail with a missing-column error instead of returning no rows. Add both columns to CREATE TABLE and add matching ADD COLUMN IF NOT EXISTS statements. The inspected lookups do not require node_id.

46-46: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Detect template expressions without stopping at inner braces.

parse_runs_on_selector uses TEMPLATE_RE to set runs_on_is_dynamic. The pattern does not match ${{ format('{0}-runner', inputs.runner) }} because [^}]+? stops at {0}. _runs_on_edges then enters the static runner lookup with the unresolved expression as a label. Detect the opening ${{ delimiter or use an expression-aware parser, and add a regression test for an expression containing braces.

Proposed fix
-TEMPLATE_RE = re.compile(r"\$\{\{\s*[^}]+?\s*\}\}")
+TEMPLATE_RE = re.compile(r"\$\{\{")
