golang-popular-libraries

Recommends production-ready Golang libraries and frameworks. Apply when the user explicitly asks for library suggestions, wants to compare alternatives, needs to choose a library for a specific task, or when a new dependency is being added to the project.

Quality

Content

57%

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

This skill provides a reasonable philosophical framework for Go library recommendations with good progressive disclosure to reference files. However, it is weakened by redundant content across sections (core philosophy, guidelines, and anti-patterns all say similar things) and a lack of concrete, actionable guidance — no example recommendations, no structured evaluation checklist, and no sample output format. The actual value likely lives in the referenced files which were not available for evaluation.

Suggestions

Add a concrete example of a library recommendation workflow: e.g., 'User asks for HTTP router → check net/http → if need path params/middleware, recommend chi → show comparison table format'

Consolidate 'Core Philosophy', 'General Guidelines', and 'Anti-Patterns' into a single concise decision framework or checklist to eliminate redundancy

Include a structured output template for recommendations (e.g., library name, GitHub stars/maintenance status, stdlib alternative, when to use/not use, install command)

Add a concrete decision tree or flowchart: 'If stdlib covers >80% of need → use stdlib. If need X feature → recommend Y library with rationale.'

DimensionReasoningScore

Conciseness

The content is mostly efficient but includes some unnecessary padding. The 'Core Philosophy' and 'General Guidelines' sections overlap significantly (both emphasize stdlib-first, simplicity, maturity). The 'Anti-Patterns to Avoid' section largely restates the guidelines in negative form. The persona line and closing reminder ('The best library is often no library at all') are redundant given the repeated stdlib-first messaging.

2 / 3

Actionability

The skill provides directional guidance (assess requirements, check stdlib, prioritize maturity) but lacks concrete examples. There are no specific library recommendations inline, no example recommendation format, no sample comparison output, and no executable code. The actual actionable content is deferred entirely to reference files which were not provided for evaluation.

2 / 3

Workflow Clarity

There is a loose sequence implied (assess requirements → check stdlib → evaluate maturity → consider complexity → think about dependencies), but it lacks explicit validation checkpoints. For a recommendation skill, there's no structured output format, no checklist for evaluating a library (e.g., check last commit date, check license, check dependency count), and no decision tree or flowchart for when to recommend stdlib vs external.

2 / 3

Progressive Disclosure

The skill has a clean overview structure with well-signaled one-level-deep references to three categorized reference files (stdlib.md, libraries.md, tools.md), plus cross-references to related skills. The external awesome-go link is appropriate. Navigation is clear and organized. However, since no bundle files were provided, we cannot verify the referenced paths actually exist.

Description

89%

Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.

This is a well-crafted description with strong trigger terms and explicit 'when' guidance. Its main weakness is that the 'what' portion could be more specific about the concrete actions performed (e.g., evaluating maintenance status, comparing benchmarks, checking license compatibility). Overall it performs well for skill selection purposes.

Suggestions

Add more specific concrete actions to the 'what' portion, e.g., 'Recommends production-ready Golang libraries and frameworks by evaluating popularity, maintenance status, and API design' to boost specificity.

DimensionReasoningScore

Specificity

Names the domain (Golang libraries and frameworks) and the core action (recommends), but doesn't list multiple specific concrete actions beyond recommending. It mentions comparing alternatives and choosing libraries, which adds some specificity, but these are still fairly general.

2 / 3

Completeness

Clearly answers both 'what' (recommends production-ready Golang libraries and frameworks) and 'when' (explicit 'Apply when...' clause listing four distinct trigger scenarios including asking for suggestions, comparing alternatives, choosing for a task, or adding a dependency).

3 / 3

Trigger Term Quality

Includes natural keywords users would say: 'library suggestions', 'compare alternatives', 'choose a library', 'dependency', 'Golang'. These cover common variations of how a user would phrase requests for library recommendations.

3 / 3

Distinctiveness Conflict Risk

Clearly scoped to Golang library/framework recommendations specifically, which is a distinct niche. The combination of 'Golang' + 'library recommendations' makes it unlikely to conflict with general coding skills or other language-specific skills.
