Quality

Content

70%

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

The content is concise and well-structured with proper progressive disclosure to a real reference file. It falls short on actionability and workflow clarity because the body offers prose directives rather than executable commands and lacks explicit validation checkpoints for a change that can delist a site.

Suggestions

Add an executable check command to the Check section, e.g. `curl -I "$ORIGIN/robots.txt"` and a grep for `Disallow: /`, so guidance is copy-paste ready.

Insert an explicit validate-then-proceed checkpoint (fetch, verify HTTP 200 and no site-wide Disallow, only then edit) to support the risky crawl-affecting change.

Move or mirror the concrete robots.txt directive example from the reference into the Fix section so the body stands on its own.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence — short Quick Reference, Check, Fix, Explain, and Code Review sections with no padding or explanation of basic concepts.

3 / 3

Actionability

The Check/Fix sections give concrete direction ('Fetch /robots.txt... verify HTTP 200', 'Add a live Sitemap: line', 'Remove any Disallow: / rules') but no executable commands or code in the body itself, so guidance is actionable but not copy-paste ready.

2 / 3

Workflow Clarity

The Check→Fix→Explain→Code Review sections imply a sequence, but there are no explicit validation checkpoints or verify-then-fix feedback loops in the body for this crawl-affecting change.

2 / 3

Progressive Disclosure

A concise overview body signals a single one-level-deep reference ('see references/rule.md') that exists, with content appropriately split between the overview and the detailed rule page.

Description

50%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

The description provides explicit when-to-use triggers but omits the concrete capability (publishing/auditing/fixing robots.txt), making the 'what' implicit. Trigger terms are relevant but miss the central keyword 'robots.txt'.

Suggestions

State the concrete capability, e.g. 'Publishes and audits a valid robots.txt file and verifies crawl directives.'

Include the keyword 'robots.txt' and natural variants like 'crawling' and 'indexing' in the trigger clause.

Narrow 'applies to any public website' to a more distinctive scope tied to robots.txt / crawl control to reduce overlap with other SEO skills.

DimensionReasoningScore

Specificity

The phrase 'auditing technical SEO foundations or diagnosing crawl coverage gaps' names a domain and some activities, but no concrete robots.txt actions (publish, audit, fix) are stated, so it does not reach a comprehensive list of specific actions.

2 / 3

Completeness

Two explicit 'Use when...' clauses cover the 'when', but the 'what' is never concretely stated — the description does not say what the skill does to robots.txt, leaving the capability implicit.

2 / 3

Trigger Term Quality

Terms like 'public website', 'technical SEO foundations', and 'crawl coverage gaps' are somewhat relevant, but the core term 'robots.txt' and common variants ('crawling', 'indexing') are missing.

2 / 3

Distinctiveness Conflict Risk

'Applies to any public website' and 'technical SEO foundations' are broad enough to overlap with many other SEO skills, though the crawl-coverage framing narrows it somewhat.
