matter-workspace

Manage matter workspaces — create, list, switch, close, or detach (practice-level). Keeps one client or engagement's context separate from every other for multi-client practitioners. Use when the user wants to open a new matter, switch matters, list matters, close/archive a matter, or work at practice-level only.

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-organized, highly actionable instruction-only skill with clear sequenced workflows and validation checkpoints. Its main weaknesses are structural redundancy between the two halves of the document and the absence of any progressive disclosure into reference files.

Suggestions

Merge the top "Subcommands"/"Instructions" section with the bottom "Subcommand logic" section to eliminate the duplicated dispatch logic and reduce tokens.

Move the matter.md and history.md templates (and possibly the storage-layout tree) into a reference file under references/ and link to it, so SKILL.md stays a lean overview.

Consolidate the "Notes", "Cross-matter context", and "What this skill does not do" sections into one place to avoid restating the same constraints twice.

Dimension	Reasoning	Score
Conciseness	The body is split by a `---` divider into a brief top section and a detailed bottom section that overlap — "Subcommands" vs "Subcommand logic" and "Notes" vs "Cross-matter context"/"What this skill does not do" — so it could be tightened despite being accurate.	2 / 3
Actionability	Concrete file paths, an explicit intake field list, ready-to-use matter.md/history.md templates, and an exact list table format give copy-paste-ready instruction-only guidance.	3 / 3
Workflow Clarity	Each subcommand is a clear numbered sequence with validation checkpoints (confirm slug not present, confirm matter.md exists, "confirm before writing") and error-recovery branches (offer `new` on missing switch target).	3 / 3
Progressive Disclosure	It is a ~175-line single file with no bundle files or external references; the matter.md/history.md templates and storage layout are inline content that would be better split into reference files, so organization is good but disclosure is not layered.	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, third-person description that names concrete actions, provides natural trigger terms, and explicitly pairs what-it-does with when-to-use guidance. It is concise without fluff and occupies a clear niche.

Dimension	Reasoning	Score
Specificity	"create, list, switch, close, or detach (practice-level)" lists multiple specific concrete actions, matching the score-3 anchor.	3 / 3
Completeness	It answers what ("Manage matter workspaces — create, list, switch, close, or detach") and when (explicit "Use when the user wants to..." clause), satisfying the score-3 anchor.	3 / 3
Trigger Term Quality	"open a new matter, switch matters, list matters, close/archive a matter, or work at practice-level only" are natural terms a practitioner would say, giving good coverage.	3 / 3
Distinctiveness Conflict Risk	Matter-workspace management for multi-client practitioners is a clear niche with distinct triggers unlikely to conflict with other skills.	3 / 3
