The description names the domain (technical SEO) and mentions several areas like 'crawlability, indexation, or performance issues,' but it describes categories of work rather than listing multiple specific concrete actions (e.g., 'generate XML sitemaps, analyze robots.txt, audit meta tags, check page speed').

The description is framed as a 'when' clause ('When the user needs...'), which addresses when to use the skill, but the 'what does this do' is only implied through the trigger conditions rather than explicitly stated as concrete capabilities. The what and when are conflated rather than clearly separated.

Includes strong natural keywords users would say: 'SEO audit,' 'on-page optimization,' 'crawlability,' 'indexation,' 'performance issues,' and 'search rankings.' These cover a good range of terms a user seeking SEO help would naturally use.

Technical SEO is a clear niche with distinct trigger terms like 'SEO audit,' 'crawlability,' 'indexation,' and 'on-page optimization' that are unlikely to conflict with other skills.

The skill is fairly comprehensive but includes some unnecessary explanation that Claude would already know (e.g., explaining what HTTPS is, what canonical tags are, what mixed content means). Some bullet points could be tightened—for instance, the Core Web Vitals section explains what LCP/INP/CLS are rather than just stating targets and fixes. However, it's not egregiously verbose and most content is informational rather than padded.

The skill provides structured checklists and specific metrics targets (LCP < 2.5s, INP < 200ms, CLS < 0.1), which is good. However, it lacks executable code/commands—no actual robots.txt examples, no schema markup JSON-LD snippets, no command-line tools for validation, no concrete Search Console API queries. The guidance is specific in what to check but not copy-paste ready for implementation.

The 9-dimension audit workflow is clearly sequenced and logically ordered (crawlability first, then indexation, etc.). The output format includes prioritization tiers. However, there are no explicit validation checkpoints or feedback loops—no 'verify fix worked' steps, no 're-check after implementing changes' guidance, and no error recovery paths within the audit process itself.

The content is well-structured with clear sections (When to Use, Context Required, Workflow, Output Format, Frameworks, Examples), and references related skills at the end. However, the main body is quite long (~120+ lines of dense content) and could benefit from splitting detailed dimension audits into separate reference files, keeping SKILL.md as an overview with links to detailed checklists per dimension.
