matter-workspace

Manage matter workspaces — new, list, switch, close, or detach (practice- level). Creates, lists, switches, closes, and detaches the active matter so context from one client engagement never leaks into another. Use when a multi-client practitioner says "new matter", "switch matter", "list my matters", "close this matter", or needs to manage which matter is active.

Quality

Content

85%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.

The body is a well-structured, highly actionable instruction skill with clear per-subcommand workflows and appropriate organization. Its only weakness is conciseness: path duplication and a repeated disabled-state explanation add tokens without adding information.

Suggestions

Define the base path once as a variable or short alias and reference it thereafter, instead of repeating '~/.claude/plugins/config/claude-for-legal/employment-legal/matters/' in full several times.

Remove the duplicate disabled-state guidance in the Reference section (lines 44-48), since the same message already appears in step 1 of the Instructions.

Consider moving the full matter.md and history.md templates to a reference file and linking from the body, which would tighten the main skill further while keeping templates discoverable.

Dimension	Reasoning	Score
Conciseness	Mostly efficient and free of basic-concept padding, but it repeats the full base path verbatim several times and restates the disabled-state message in both the Instructions and the Reference section, so it could be tightened.	2 / 3
Actionability	As an instruction-only skill it provides concrete, copy-paste-ready guidance — exact file paths, the precise 'Active matter:' edit target, a full matter.md template, and a history.md seed — without falling back to pseudocode or vague direction.	3 / 3
Workflow Clarity	Each subcommand is clearly sequenced (new=6 steps, close=4, switch=3) with explicit confirmation checkpoints and existence checks; archive moves are non-destructive and gated, so the missing formal validate-fix-retry loop does not cap the score.	3 / 3
Progressive Disclosure	No bundle files exist and none are needed for this self-contained file-management skill; the body is well-organized with clear section headers, satisfying the simple-skill allowance for a score of 3.	3 / 3

Description

100%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.

The description is third-person, concise, and fully satisfies all four dimensions: concrete actions, natural trigger terms, explicit what-and-when guidance, and a distinctive niche. It matches the strongest reference examples in the rubric.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'Creates, lists, switches, closes, and detaches the active matter' — mirroring the score-3 anchor's enumeration of specific verbs.	3 / 3
Completeness	Clearly states both what it does ('Manage matter workspaces — new, list, switch, close, or detach') and when to use it with an explicit 'Use when...' clause, matching the score-3 anchor exactly.	3 / 3
Trigger Term Quality	Explicit natural trigger phrases a user would say — '"new matter", "switch matter", "list my matters", "close this matter"' — giving good coverage of common variations.	3 / 3
Distinctiveness Conflict Risk	Targets a clear niche — multi-client matter isolation — with triggers specific to that workflow, making it unlikely to fire for unrelated skills.	3 / 3
	Total	12 / 12 Passed
