Issues
Warnings (3)
14.1-no-success-criterialine 1
No concrete success criteria found for eval readiness
Fix: Add pass/fail criteria or measurable outcomes (e.g., 'must return valid JSON', 'output < 100 lines')
4.5-desc-no-triggersline 2
Description lacks triggering conditions
Fix: Add phrases like 'Use when...', 'Triggers on...', or 'Applies to...' to help Claude select this skill
1.2-desc-whenline 3
Description missing WHEN clause - recommended by agentskills spec
Fix: Consider adding 'Use when...' or 'Activate when...' to description
Suggestions (5)
17.1-no-input-contractline 7
No input contract found; unclear what data the skill expects
Fix: Document what the skill expects as input (format, required fields, constraints)
17.2-no-output-contractline 7
No output contract found; unclear what the skill produces
Fix: Document what the skill produces (format, structure, side effects)
14.2-no-examplesline 1
No input/output examples found
Fix: Add example input/output pairs or <example> blocks to make the skill testable
3.4-gerund-namingline 2
Skill name could use gerund form for clarity
Fix: Consider gerund-style names like 'processing-pdfs' or 'analyzing-logs' (per best practices)
1.19-non-portable-fieldline 4
Frontmatter keys outside the agentskills spec: disable-model-invocation. Claude Code loads the skill with them; claude.ai uploads and the Skills API reject it with 'Unexpected key(s)'
Fix: Nothing to do for Claude Code or plugin distribution. To upload to claude.ai or the Skills API, ship frontmatter with only name, description, license, compatibility, metadata and allowed-tools
