matter-workspace

Manage matter workspaces for multi-client practices — create, list, switch, close, or detach the active matter. Use when the user wants to create a new matter workspace, switch the active matter, list matters, archive a matter, or work at practice-level only without an active matter.

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.

Highly actionable and clearly sequenced with solid validation checkpoints, but the body is longer than necessary due to duplicated subcommand/disabled-state content across its two sections and keeps all templates inline rather than splitting them into reference files.

Suggestions

Collapse the two parallel sections into one: keep a single subcommand-logic block and remove the duplicated 'Instructions' dispatch and disabled-state prose (it already appears under 'Matter Workspace').

Move the matter.md and history.md templates into a references/ file (e.g. references/matter-template.md) and link to it, so the SKILL.md body stays an overview and progressive disclosure becomes one level deep.

De-duplicate the slug rule and the 'do not delete, archive' note so each appears once.

Dimension	Reasoning	Score
Conciseness	Operational and largely lean, but the body carries two parallel sections (the /matter-workspace command block and the 'Matter Workspace' reference) that duplicate subcommand logic, the disabled-state explanation, and the 'Slugs are lowercase with hyphens' rule.	2 / 3
Actionability	Concrete file paths, exact storage layout, complete matter.md/history.md templates, and a dispatch table make the guidance copy-paste ready; absence of code is fine for this instruction-only skill.	3 / 3
Workflow Clarity	Each subcommand has numbered steps with explicit checkpoints — slug-uniqueness and existence checks, 'confirm before writing', 'do not auto-switch — ask', and offer-to-create fallbacks — providing clear validation and error-recovery loops.	3 / 3
Progressive Disclosure	Well-sectioned with clear headers, but everything (templates, storage layout, cross-matter policy) is inline in a single ~185-line file with no bundle files or one-level-deep references to split out the templates.	2 / 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.

A strong description: third-person voice, concrete enumerated actions, and an explicit 'Use when' trigger clause covering both what and when. It is distinguishable from other skills and free of vague fluff.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'create, list, switch, close, or detach the active matter' — matching the anchor for enumerated specific capabilities.	3 / 3
Completeness	Explicitly states both what it does (manage/CRUD matter workspaces) and when to use it via a clear 'Use when...' clause with enumerated triggers.	3 / 3
Trigger Term Quality	Covers natural phrasings a user would say ('create a new matter workspace', 'switch the active matter', 'list matters', 'archive a matter') with good variation coverage.	3 / 3
Distinctiveness Conflict Risk	Targets a clear niche (multi-client matter workspaces) with distinct, domain-specific triggers unlikely to fire for unrelated skills.	3 / 3
