TRIGGER-05 Invocation flags are consistent
SKILL.md:5an invocable artifact user-invocable: false — the user can never invoke it
`user-invocable: false` combined with `disable-model-invocation: true` means no one can ever invoke this artifact.
user-invocable: false
SKILL.md:6 disable-model-invocation: true — the model can never invoke it either
Both invocation paths are closed — the artifact is dead weight loaded into every session.
disable-model-invocation: true
Fix Re-open one invocation path (drop one of the two flags), or delete the artifact if nothing should invoke it.
VERIFY-01 Evals or tests present
SKILL.md:1the skill works no evals/, tests/, or verification section found
No way to prove the skill does what it claims.
Fix Add an evals/ folder (test prompts + expected outcomes) and a '## Verify' step in the body.
