Hreflang and international SEO audit, validation, and generation. Detects common mistakes, validates language/region codes, and generates correct hreflang implementations. Use when user says "hreflang", "i18n SEO", "international SEO", "multi-language", "multi-region", or "language tags".

Quality

Content

72%

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

The body is a well-organized, actionable reference with complete code examples and appropriately split one-level-deep references. Its main weaknesses are some redundancy between the validation checks and the common-mistakes table, and a missing explicit error-recovery loop in the generation workflow.

Suggestions

Consolidate the redundancy between the numbered "Validation Checks" sections and the "Common Mistakes" table — either fold the severity/fix info into the checks or move the table to a reference file.

Add an explicit feedback loop to the "Hreflang Generation" process (e.g., "if any code or return-tag check fails, regenerate the affected tags and re-verify before outputting").

Either reference or remove the orphaned `references/machine-translation-qa.md`, which exists in the bundle but is not cited anywhere in the body.

DimensionReasoningScore

Conciseness

The body is information-dense and largely assumes competence (e.g., the ccTLD hierarchy heuristic, the 2022 GSC removal), but the "Common Mistakes" table substantially restates the numbered "Validation Checks" sections, which is duplicative and could be tightened.

2 / 3

Actionability

Complete, copy-paste-ready code blocks are provided for all three methods (HTML <link> tags, HTTP Link headers, XML sitemap with xmlns:xhtml namespace) plus a concrete numbered generation process.

3 / 3

Workflow Clarity

The "Hreflang Generation" process is a clear 7-step sequence with validation embedded (steps 3 and 5), but it lacks an explicit validate→fix→retry feedback loop in the core workflow, which the rubric expects for batch/validation operations.

2 / 3

Progressive Disclosure

References are one level deep, clearly signaled inline ("Load `references/X.md`"), and consolidated in a "Reference Files" section with on-demand guidance; detail is appropriately offloaded to bundle files.

Description

100%

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 is concise, uses third-person voice, names concrete actions, and includes an explicit "Use when" clause with natural trigger terms. It clearly communicates both capability and invocation conditions with no over-claims.

DimensionReasoningScore

Specificity

"audit, validation, and generation" plus "Detects common mistakes, validates language/region codes, and generates correct hreflang implementations" lists multiple concrete, distinct actions, matching the anchor for listing several specific concrete actions.

3 / 3

Completeness

It explicitly answers both what ("Hreflang and international SEO audit, validation, and generation…") and when ("Use when user says…"), satisfying the explicit-trigger anchor for a full what+when answer.

3 / 3

Trigger Term Quality

Natural trigger phrases a user would actually say are listed ("hreflang", "i18n SEO", "international SEO", "multi-language", "multi-region", "language tags"), giving good coverage of common variations.

3 / 3

Distinctiveness Conflict Risk

Hreflang/international SEO is a clear niche with distinctive triggers, making it unlikely to fire for an unrelated skill.
