matter-workspace

Manage matter workspaces — new, list, switch, close, or detach (practice-level). File-management logic for keeping one client or engagement's context separate from every other. Use when working across multiple clients or matters, when the user says "new matter", "switch matter", "list matters", "close matter", or when any substantive skill needs to know which matter it's working in.

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.

The body is highly actionable with well-sequenced, validated workflows and concrete templates, but it is somewhat verbose due to repeated subcommand listings and rationale restatements, and it makes no use of progressive disclosure to separate files.

Suggestions

Remove the duplicate top-level "Subcommands" list or the later "Subcommand logic" section — keep one canonical listing to reduce redundancy and token cost.

Drop or compress the "Multi-client practitioners ... thin file-management layer" paragraph since it restates the opening rationale.

Consider moving the matter.md template and history.md seed into reference files under ./references/ and linking to them, so SKILL.md stays a lean overview.

Dimension	Reasoning	Score
Conciseness	Mostly efficient operational detail, but the subcommand list appears twice (top "Subcommands" and later "Subcommand logic") and the intro/rationale paragraph ("Multi-client practitioners ... thin file-management layer") restates the opening, so it could be tightened.	2 / 3
Actionability	Concrete and copy-paste ready: exact storage paths, a dispatch table on $ARGUMENTS, a full matter.md template, a history.md seed, and a list-table format. Absence of code is fine for this instruction-only skill since the guidance is specific and actionable.	3 / 3
Workflow Clarity	Each subcommand is a clearly numbered sequence with explicit validation/confirmation checkpoints (confirm slug not already present, confirm matter.md exists, confirm-before-writing, show summary on switch), and the destructive close is guarded.	3 / 3
Progressive Disclosure	Well-organized into sections, but it is a monolithic single file with no bundle references; substantial content (the matter.md template, history.md seed, full per-subcommand specs) is all inline and could be split into referenced files.	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.

The description is strong across all dimensions: it names concrete actions, gives natural trigger terms, and covers both what and when explicitly with a distinctive niche. No changes needed.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — "new, list, switch, close, or detach" — and describes the file-management function precisely rather than vaguely.	3 / 3
Completeness	Explicitly answers both what ("Manage matter workspaces ... File-management logic for keeping one client or engagement's context separate") and when ("Use when working across multiple clients or matters, when the user says ...").	3 / 3
Trigger Term Quality	Includes natural phrases a user would say ("new matter", "switch matter", "list matters", "close matter", "working across multiple clients or matters") with good coverage of common variations.	3 / 3
Distinctiveness Conflict Risk	Targets a clear niche — legal matter workspace file isolation — with distinct triggers unlikely to fire for unrelated skills.	3 / 3
