matter-workspace

Manage matter workspaces — create, list, switch, close, or detach the active matter so multi-client practitioners keep one client's context separate from every other. Read by any substantive skill that needs to know what matter it's working in. Use when user says "new matter", "switch matter", "list matters", "close matter", or wants to work at practice-level only.

Quality

Content

65%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 exact paths, templates, and concrete per-subcommand workflows, and it is well sectioned. Its weaknesses are repetition of the subcommand list across three sections, lack of a post-operation verification loop on the destructive `close` step, and a monolithic layout with no progressive file references.

Suggestions

Consolidate the subcommand coverage: keep the detailed ## Subcommand logic steps and drop or slim the duplicate summary list and the dispatch table in ## Instructions so each command appears once.

Add a verification step to `close` (e.g., confirm `matters/_archived/<slug>/matter.md` exists after the move and re-read the practice CLAUDE.md to confirm the Active matter line) to close the destructive-operation feedback loop.

Move the full `matter.md` and `history.md` templates into a reference file (e.g. references/matter-template.md) linked from the body, turning SKILL.md into a leaner overview and improving progressive disclosure.

DimensionReasoningScore

Conciseness

The subcommands are presented three times — a summary list (## Subcommands), a dispatch table (## Instructions step 3), and detailed numbered steps (## Subcommand logic) — and the disabled/off state is explained twice (Instructions step 1 and the post-divider paragraph), so it is mostly efficient but padded with repetition that could be tightened; not 3 because of this redundancy, not 1 because no basic concepts are over-explained.

2 / 3

Actionability

Gives exact storage paths, precise edits ("update the `Active matter:` line"), a full matter.md template, a history.md seed, and a concrete intake field list — fully actionable, copy-ready instruction despite being instruction-only.

3 / 3

Workflow Clarity

Each subcommand is clearly sequenced with numbered steps and pre-checks (confirm slug not present, confirm matter.md exists), but `close` is a destructive directory move with no post-move verification that the archive succeeded or the active-matter line updated, so per the destructive-operation guideline workflow clarity is capped at 2 rather than 3.

2 / 3

Progressive Disclosure

Well-organized with clear section headers and no nested references, but the body exceeds 50 lines as a single monolithic file with the full templates and per-subcommand logic inline and no file-based references to split detail into, fitting the "content that should be separate is inline" anchor rather than the one-level-deep reference structure of a 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 concise, third-person, and names concrete actions with an explicit "Use when" trigger clause covering natural user phrases. It cleanly distinguishes the skill's niche and is unlikely to conflict with other skills.

DimensionReasoningScore

Specificity

Lists multiple concrete actions — "create, list, switch, close, or detach the active matter" — matching the anchor for naming several specific actions rather than vague language.

3 / 3

Completeness

Explicitly answers both what ("Manage matter workspaces — create, list, switch, close, or detach") and when ("Use when user says...") with an explicit trigger clause.

3 / 3

Trigger Term Quality

Provides natural phrases a user would say — "new matter", "switch matter", "list matters", "close matter", "work at practice-level only" — giving good coverage of real trigger terms.

3 / 3

Distinctiveness Conflict Risk

Occupies a clear niche — multi-client matter isolation — with distinct triggers unlikely to fire for unrelated skills; not score 2 because it is not merely domain-named but operationally distinct.
