Quality

Content

77%Weight 40%Scale 1-3

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

A well-structured instruction skill with an actionable template and clear validation checkpoints, but it is verbose: the central 'don't write the brief for the student' rule is repeated across four sections, and all content is inlined rather than progressively disclosed.

Suggestions

Consolidate the repeated 'don't brief it for me' message into one authoritative section; the other sections can reference it instead of restating it.

Extract the default brief template into a reference file (e.g. references/template.md) and link to it, improving progressive disclosure and trimming the main body.

Trim aphoristic padding (e.g. "A brief you didn't write is a brief you won't remember") where the concrete rules already convey the same point.

Dimension	Reasoning	Score
Conciseness	It avoids explaining concepts Claude already knows, but the same core rule (don't brief it for them) is restated across Confidence discipline, the 'don't brief it for me' rule, Mode fork, and 'What this skill does not do', and aphorisms like "A brief you didn't write is a brief you won't remember" add padding that could be tightened.	2 / 3
Actionability	Concrete, copy-paste-ready brief template plus specific follow-up questions ("What were the key facts the court actually relied on?", "Why did the court reject the dissent's framing?") and explicit per-mode behavior give fully executable guidance.	3 / 3
Workflow Clarity	The drill-me holding check ("If they can't state it, make them read it again") and the [UNCERTAIN]/[VERIFY] flagging act as explicit validation checkpoints within a sequenced load-context → mode-fork → scaffold → review flow.	3 / 3
Progressive Disclosure	Sections are clearly headed and there are no 2+ level nested references, but the full template and detailed mode rules are inline in a single 80+ line file rather than split into a one-level-deep reference, and no bundle files are used.	2 / 3

Description

90%Weight 40%Scale 1-3

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

A concise, well-constructed description that clearly answers both what the skill does and when to use it, with natural trigger terms and a distinct niche. The only soft spot is capability specificity, which lists a couple of actions rather than a comprehensive set.

Dimension	Reasoning	Score
Specificity	"Brief a case in your preferred format" and "makes the student state the holding first" name the domain and two actions, but the action list is not comprehensive, matching the anchor that names domain and some actions.	2 / 3
Completeness	It states what the skill does ("Brief a case in your preferred format") and provides an explicit 'Use when...' clause covering several triggers, answering both what and when.	3 / 3
Trigger Term Quality	"Use when the user says 'brief [case]', 'what's the holding in', 'case brief', or pastes a case" gives strong coverage of the natural phrases a user would actually say when they need this skill.	3 / 3
Distinctiveness Conflict Risk	The legal case-briefing niche and triggers like "brief [case]" and "what's the holding in" are distinct and unlikely to fire for unrelated skills.	3 / 3
