design-system

Guided, section-by-section GDD authoring for a single game system. Gathers context from existing docs, walks through each required section collaboratively, cross-references dependencies, and writes incrementally to file.

Quality

Content

77%

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

The content is highly actionable with an excellently sequenced and validated workflow, but it is over-long due to repeated review-mode blocks and keeps large reusable blocks inline rather than splitting them into reference files.

Suggestions

Factor the repeated solo/lean/full review-mode check into a single defined rule referenced once, instead of restating the three-case block in each section.

Move the specialist routing table, the GDD skeleton template, and the per-section completion-steering formats into separate reference files (e.g. references/routing.md, references/gdd-template.md) and link to them, reducing the main file's size.

Trim the closing 'Collaborative Protocol' section, which largely restates principles already enforced inline in each phase.

DimensionReasoningScore

Conciseness

The body is substantive domain guidance with no extraneous concept explanations, but the solo/lean/full review-mode block is repeated near-verbatim across ~8 sections and the closing 'Collaborative Protocol' recap restates principles already detailed earlier, so it could be meaningfully tightened.

2 / 3

Actionability

Provides fully concrete, copy-paste-ready guidance — exact AskUserQuestion prompts with specific option text, exact file paths, exact Grep patterns, exact Edit old_string/new_string patterns, and a complete GDD template with structured completion-steering formats.

3 / 3

Workflow Clarity

A clearly sequenced five-phase flow with a defined per-section cycle and explicit validation checkpoints (registry conflict checks after each write, 5a self-check, approval gates, BLOCKED verdicts) plus feedback loops and a recovery/resume section.

3 / 3

Progressive Disclosure

The skill is a single monolithic ~870-line file with no bundle reference files; the routing table, GDD template, engine-domain table, and completion-steering formats are all inline where they could be split out, though external doc references are clearly signaled.

Description

67%

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 specific, actionable, and clearly niche-specific, but it lacks an explicit 'Use when…' trigger clause and broader natural-language trigger terms, leaving the 'when to use it' only implied.

Suggestions

Add an explicit trigger clause, e.g. 'Use when designing or authoring a single game system's GDD, or retrofitting an existing GDD to fill missing sections.'

Broaden trigger terms with natural phrasings users would say — 'design a game system', 'write a game design document', 'fill in a GDD' — alongside 'GDD authoring'.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — 'Gathers context from existing docs', 'walks through each required section collaboratively', 'cross-references dependencies', 'writes incrementally to file' — matching the multiple-specific-actions anchor.

3 / 3

Completeness

The 'what' is clearly and comprehensively stated, but there is no 'Use when…' or equivalent explicit trigger clause, so the 'when' is only implied and completeness is capped at 2 per the judging guidelines.

2 / 3

Trigger Term Quality

'GDD authoring' and 'game system' are natural terms, but capability phrases like 'writes incrementally to file' are not user-spoken triggers and common variations such as 'design' or 'write a GDD' are missing.

2 / 3

Distinctiveness Conflict Risk

'GDD authoring for a single game system' is a narrow, well-defined niche with distinct triggers, making it unlikely to fire for an unrelated skill.
