✗ STRUCT-01 Valid YAML frontmatter
SKILL.md:1— → YAML parser rejected the frontmatter block
Frontmatter failed to parse: Nested mappings are not allowed in compact mappings at line 2, column 14: description: Expert skill for resolving build errors with minimal change princi… ^
Fix Fix the YAML so it is a valid `key: value` mapping between the opening and closing `---` fences.
✗ STRUCT-02 Recommended fields present
SKILL.md:1
No frontmatter to read fields from (see STRUCT-01).
Fix Add frontmatter with a `description` field.
✗ TRIGGER-02 Description long enough to anchor invocation
SKILL.md:1
No description — nothing for the model to match against.
Fix Add a description that leads with the use case and the phrases a user would say.
✗ TRIGGER-03 Invocation cues in the description
SKILL.md:1
No description — no invocation cues possible.
Fix Add a description with explicit cues: 'Use when …' plus the phrases a user would say.
✗ 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.
✗ CLARITY-03 No ASCII-art / persona filler

⚠ TOKEN-02 Progressive disclosure
SKILL.mdeverything inlined in SKILL.md → 353 body lines, 0 supporting files
Large SKILL.md (353 lines) with no supporting files — all of it loads every time the skill fires.
Fix Move heavy reference material into supporting files and link to them, so the model loads it only when needed.
