Issues
Warnings (5)
16.1-no-stop-conditionline 7
Complex skill lacks explicit stop conditions
Fix: Add stop/termination criteria (e.g., 'Stop after N iterations', 'Abort if error rate exceeds threshold')
19.3-generator-no-output-specline 7
Generator pattern detected but no output format specified
Fix: Document the output format (template, schema, or example output)
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-whatline 3
Description missing WHAT clause (action verb) - recommended by agentskills spec
Fix: Consider starting with what the skill does, e.g., 'Creates...', 'Generates...', 'Validates...'
1.2-desc-whenline 3
Description missing WHEN clause - recommended by agentskills spec
Fix: Consider adding 'Use when...' or 'Activate when...' to description
Suggestions (12)
16.4-no-idempotencyline 7
Skill does not document whether it is safe to re-run
Fix: Add idempotency guidance: state whether running the skill twice produces the same result or causes side effects
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)
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)
18.1-no-confidence-signalline 1
No confidence signal found for orchestrator decision-making
Fix: Add confidence indicators (e.g., confidence: high/medium/low) so orchestrators can route or retry
18.3-no-structured-outputline 1
No structured output format defined for machine consumption
Fix: Define a structured output format (JSON, YAML, or table) so downstream tools can parse results
19.6-wrapper-no-boundaryline 7
Tool Wrapper pattern detected but no API boundary documented
Fix: Document what the wrapped tool can and cannot do (scope, limitations)
4.2-ambiguous-termline 233
Ambiguous term 'appropriate' found
Fix: Replace with specific, measurable criteria
4.2-ambiguous-termline 235
Ambiguous term 'appropriate' found
Fix: Replace with specific, measurable criteria
4.2-ambiguous-termline 252
Ambiguous term 'many' found
Fix: Replace with specific, measurable criteria
4.3-output-formatline 1
Skill mentions output but doesn't specify format
Fix: Add an '## Output' section with format examples
1.4-version-top-levelline 4
Top-level 'version' field - Anthropic skills don't use this
Fix: Consider moving to 'metadata.version' or removing (version is optional)
1.19-non-portable-fieldline 4
Frontmatter keys outside the agentskills spec: version. 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
