27%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill attempts to be a comprehensive encyclopedia of Elm-to-F# migration but suffers severely from verbosity and poor content organization. Hundreds of lines are spent teaching Claude basic Elm and F# syntax it already knows, while the genuinely useful project-specific guidance (Morphir IR fidelity requirements, Myriad integration, coordination workflows) is buried deep in the document. The content would benefit enormously from aggressive trimming and splitting into referenced sub-files.
Suggestions
Remove or drastically reduce Sections 1 (Language Expertise) and 2 (Type System Mapping) — Claude already knows Elm and F# syntax. Replace with a concise mapping table (Elm concept → F# equivalent → key gotchas) of no more than 30 lines.
Split the monolithic file into referenced sub-files: move pattern catalog details to patterns/*.md, decision trees to a separate file, UI migration to its own file, and automation script docs alongside the actual scripts. Keep SKILL.md as a concise overview with clear navigation links.
Provide the actual automation scripts (analyze-elm-module.fsx, extract-elm-tests.fsx, etc.) in the bundle rather than just describing their interfaces — currently the actionability of the automation workflow is undermined by missing implementations.
Add explicit error recovery steps to the verification workflow: what specific actions to take when JSON roundtrip fails, when AOT warnings appear, or when compatibility tests show divergences.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | This skill is extremely verbose at ~1500+ lines. It extensively explains concepts Claude already knows (Elm syntax, F# syntax, what Option/Result types are, basic pattern matching, how JSON serialization works). Massive code examples for basic language features like Maybe→Option and Result→Result waste tokens on things Claude is deeply familiar with. The Elm and F# mastery sections alone are hundreds of lines of tutorial content. | 1 / 3 |
Actionability | The skill provides many concrete code examples that are mostly executable, and includes specific CLI commands for automation scripts. However, much of the code is illustrative rather than project-specific (e.g., generic Elm/F# syntax examples), and key scripts referenced (analyze-elm-module.fsx, extract-elm-tests.fsx) are described but not provided in the bundle, making the automation guidance incomplete. | 2 / 3 |
Workflow Clarity | The migration workflow in Section 9 has clear phases with checklists and the verification phase includes explicit validation steps (JSON roundtrip, AOT checks). However, the workflow is buried deep in a massive document, and the validation steps lack specific error recovery guidance—e.g., what to do when JSON roundtrip fails or when AOT warnings appear. The coordination workflows with other 'gurus' describe handoffs but lack concrete validation checkpoints. | 2 / 3 |
Progressive Disclosure | This is a monolithic wall of text with everything inlined into a single massive file. References to pattern catalog files (patterns/custom-types.md, etc.), templates, and scripts are mentioned but none are provided in the bundle. Content that should clearly be in separate files (language syntax references, pattern catalog entries, decision trees, UI migration guides) is all crammed into the main SKILL.md. | 1 / 3 |
