Summary

  • normalize PAT, PAT request, and app installation permissions into query-friendly scope:access lists
  • separate organization and repository permission buckets for fine-grained PATs and PAT requests
  • update credential node docs and Tier Zero rules for the normalized permission shape

Testing

  • uv run pytest
  • uv run ruff check src/openhound_github/models/permissions.py src/openhound_github/models/personal_access_token.py src/openhound_github/models/personal_access_token_request.py src/openhound_github/models/app_installation.py src/openhound_github/models/workflow.py src/openhound_github/models/workflow_job.py tests/test_credential_permission_models.py

Summary by CodeRabbit

  • New Features

    • Added graph relationships for runner scheduling, job interception, secret access, and OIDC token requests.
    • Added effective workflow and job permission visibility, runner selector details, and deployment metadata.
    • Standardized credential permissions into readable scope-and-access lists.
  • Bug Fixes

    • Improved runner discovery when organization details are unavailable.
    • Refined Tier Zero detection to focus on repository-control permissions.
    • Improved handling of special characters in workflow values.
  • Documentation

    • Expanded GitHub node and relationship documentation with property references and diagrams.

Walkthrough

The change normalizes GitHub permissions, resolves workflow policies and runners, adds secret and OIDC capability relationships, improves lookup resilience, and updates graph schema, documentation, and tests.

Changes

GitHub workflow security modeling

Layer / File(s) Summary
Permission normalization and repository policy
src/openhound_github/models/permissions.py, src/openhound_github/models/app_installation.py, src/openhound_github/models/personal_access_token.py, src/openhound_github/models/personal_access_token_request.py, extension/privilege_zone_rules/*, src/openhound_github/resources/organization.py, tests/test_credential_permission_models.py, tests/test_workflow_resources.py, tests/test_repository_rulesets.py
Permission payloads now use normalized scope:access lists. Repository workflow permission lookups handle known, unknown, HTTP, and JSON-decoding results. Privilege rules match four explicit repository-control permissions.
Workflow selectors and effective permissions
src/openhound_github/models/workflow.py, src/openhound_github/models/workflow_job.py, descriptions/nodes/GH_Workflow.md, descriptions/nodes/GH_WorkflowJob.md
Workflow jobs now expose parsed runs-on selectors and effective token permissions. Workflow and job properties include normalized permission metadata.
Self-hosted runner resolution and interception
src/openhound_github/lookup.py, src/openhound_github/kinds/edges.py, extension/schema.json, descriptions/nodes/GH_*Runner.md, tests/test_runner_models.py
Runner matching records source precedence, reuses validated organization IDs, and supports scheduling and interception relationships. Missing organization IDs no longer prevent repository runner results.
Secret and OIDC capability edges
src/openhound_github/models/workflow_job.py, extension/schema.json, descriptions/edges/*, descriptions/nodes/GH_*Secret.md, descriptions/nodes/GH_Environment.md, tests/test_workflow_interception_path.py, tests/test_workflow_model.py
Workflow jobs now emit traversable secret-access and OIDC token-request relationships. Cypher matcher values escape backslashes and single quotes before interpolation.
Platform metadata and graph documentation
descriptions/nodes/*, scripts/generate_gh_description_docs.py
Organization and enterprise metadata, node properties, relationship diagrams, and generated-description extraction reflect the updated graph model.

In `@src/openhound_github/lookup.py`:
- Line 373: In the runner-resolution flow, resolve org_node_id once from
org_login before branching between inherited and non-inherited runners, and skip
the organization when it is None. Reuse the validated org_node_id for
runner_node_id and both runner branches so missing organization IDs do not raise
ValueError.

In `@src/openhound_github/models/workflow_job.py`:
- Around line 544-546: Update the query composition construction around the
property matchers so workflow-derived matcher values are escaped before
interpolation: use a shared helper that escapes backslashes and single quotes,
then build the existing matcher expression with the escaped value. Preserve the
current query composition format and apply this to values sourced through
WorkflowJob.environment.

In `@src/openhound_github/resources/organization.py`:
- Around line 237-239: Update the repository workflow-permissions lookup in the
workflows transformer to catch failures from RESTClient.get and cache an empty
object on failure. Keep successful JSON responses cached unchanged, so
permission fields remain unknown while workflow records continue to be yielded
when GitHub returns a non-success response.

Resolve annotations before formatting property types.

ScimNodeProperties is a registered model with postponed annotations. property_rows passes its raw __annotations__ values to format_type, which emits str | None instead of string. Resolve each class’s annotations before formatting.

*:write might be too broad here? issues:write or statuses:write are examples that don't imply control over the code or repo.

Ditto for the PAT rule
