Content
21%Scale 1-5Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill reads more like a persona description or system prompt than an actionable skill document. It lists Haskell topics and principles repeatedly across sections but provides zero concrete code examples, patterns, or executable guidance. The content is both verbose (repeating concepts across Focus Areas/Approach/Output) and shallow (never going deep enough to be useful on any single topic).
Suggestions
Add concrete, executable Haskell code examples for at least the most common patterns (e.g., a newtype wrapper, a GADT example, an STM transaction pattern, a Megaparsec parser skeleton) to dramatically improve actionability.
Eliminate redundancy between Focus Areas, Approach, and Output sections — consolidate into a single structured reference with each concept mentioned once alongside its example.
Remove boilerplate sections ('Use this skill when/Do not use this skill when') and generic instructions ('Clarify goals, constraints, and required inputs') that Claude already knows how to do.
Either provide the referenced 'resources/implementation-playbook.md' bundle file with detailed examples, or inline the most critical patterns directly in the skill body.
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | The content is noticeably verbose with significant redundancy. The 'Use this skill when' and 'Do not use this skill when' sections are boilerplate that add no value. The 'Focus Areas', 'Approach', and 'Output' sections largely restate the same concepts (e.g., GADTs, newtypes, type families, STM/async appear multiple times). Generic instructions like 'Clarify goals, constraints, and required inputs' explain things Claude already knows. | 2 / 5 |
Actionability | The content is entirely abstract and descriptive with no concrete code examples, commands, or executable guidance. Statements like 'Use expressive types, newtypes, and invariants to model domain logic' and 'Provide modern, maintainable Haskell' are vague directions rather than actionable instructions. There are no code snippets, specific patterns, or copy-paste ready examples. | 1 / 5 |
Workflow Clarity | The 'Approach' section provides a rough numbered list but these are general principles rather than a workflow with clear steps. There are no validation checkpoints, no feedback loops, and no concrete sequencing of operations. The 'Instructions' section has a vague 4-step process that is too generic to guide any specific task. | 2 / 5 |
Progressive Disclosure | There is a reference to 'resources/implementation-playbook.md' for detailed examples, which shows some intent toward progressive disclosure. However, no bundle files exist to support this reference, the reference is buried in the instructions rather than clearly signaled, and the content that could benefit from being in separate files (Focus Areas, Output examples) is all inlined without clear organization. | 3 / 5 |
