DiffCI

Tools

Token cost is the o200k count of the tools list JSON, including schemas, before any tool is called.

• diffci_validation_plan

  Plan change-aware CI validation, affected-test selection, test impact analysis, or GitHub Actions workflow checks. Returns a safe local DiffCI command without accessing the checkout or executing it.

• diffci_interpret_report

  Validate and summarize a DiffCI observation report, including selective or full mode, affected-test counts, fallbacks, non-interference evidence, and the conservative next action.

• diffci_verify_workflow_text

  Perform a stateless preliminary safety check of GitHub Actions YAML: dedicated observer job, continue-on-error, dependency isolation, read-only permissions, and immutable DiffCI references.
