What this skill tells the agent

Validate Skills

Validate all skills in skills/ against the agentskills.io spec and Claude Code best practices.

Validation Checklist

For each skill directory, verify:

Spec Compliance (agentskills.io)

CheckRule
name format1-64 chars, lowercase alphanumeric + hyphens, no leading/trailing/consecutive hyphens
name matches directoryDirectory name must equal name field
description length1-1024 characters, non-empty
Optional fields validlicense, metadata, compatibility if present

Best Practices (Claude Code)

CheckRule
Description formatThird person, describes what + when to use
Body lengthUnder 500 lines
Loading is one-level deepSKILL.md is the only progressive-disclosure entry point: every reference file must be reachable from SKILL.md. References may cross-link each other for navigation (see note below).
Links are markdownUse [text](path) not bare filenames
No redundancyDon't repeat description in body
ConciseOnly add context Claude doesn't already have
One-level-deep vs. cross-linking. The one-level-deep rule targets progressive-disclosure loading chains — a reference that can only be discovered by loading another reference first (SKILL.md → a.md → b.md, where b.md is not linked from SKILL.md). That is a defect: it hides content from the loader. It does not forbid navigational cross-links. Per AGENTS.md, reference files end with a "Related Skills" footer linking sibling references, and this is required. A cross-link is fine as long as both endpoints are also reachable directly from SKILL.md. Only flag a reference that is reachable exclusively through another reference.

How to Run

  1. Find all skill directories: ``bash fd -t d -d 1 . skills/ ``
  1. For each skill, read SKILL.md and check against the rules above
  1. Report issues in this format: ``` ## Validation Results

### skills/example-skill

  • [PASS] name format valid
  • [FAIL] name "example" doesn't match directory "example-skill"
  • [PASS] description length OK (156 chars) ```

Assess React Native Migration

Assesses whether and how an existing mobile product should migrate to React Native. Use when auditing one or more product repositories for migration readiness, including products whose iOS, Android, and other clients live in separate directories or repositories; choosing brownfield, greenfield, or a checkpoint-based path; defining a representative trial; or preparing a baseline and ROI decision before implementation. When product scope or material evidence is unavailable, grills the stakeholder with exactly one question per turn instead of sending a questionnaire.
