# Skill invocation runtime tool fixture

```yaml qa-scenario
id: runtime-tool-skill-invocation
title: Runtime tool fixture — skill invocation
surface: runtime-tools
runtimeParityTier: optional
coverage:
  primary:
    - tools.skill-invocation
objective: Track skill invocation parity once skill tools are represented as first-class runtime tools.
successCriteria:
  - If skill_invoke is present, the fixture exercises happy and failure paths.
  - If skill_invoke is absent, the fixture records the known-broken tracking marker.

  summary: Track first-class skill invocation runtime parity coverage.

      action: keep optional until stable skill_invoke tool semantics exist
      reason: Skills are currently prompt/inventory-driven in QA, not exposed as a stable skill_invoke tool.
    knownBroken:
      issue: "#80173"
      reason: skill_invoke is not exposed by the current default tool surface.
