Convert agreed scope into a structured matter plan — phases, workstreams, milestones, dependencies, owner assignments, and matter setup decisions. Use when planning a new matter, running a kickoff, building a workstream plan, structuring phases, setting up task codes, or producing a plan to drive status reporting. Trigger on: 'build a plan', 'matter plan', 'project plan', 'what are the phases', 'workstream plan', 'how do we sequence this', 'who owns what', 'task codes', 'matter setup', 'workstream plan', 'matter plan', 'rolling wave', 'plan the next phase', 'what comes first', 'kickoff agenda'.

Discovery
100%Based on the skill's description, can an agent find and select it at the right time? Clear, specific descriptions lead to better discovery.
This is a strong, well-crafted skill description that clearly defines its domain (legal matter planning), lists specific concrete deliverables, and provides extensive trigger guidance with both a 'Use when' clause and an explicit 'Trigger on' list. The description uses proper third-person voice and covers natural user phrasings comprehensively. Minor note: 'workstream plan' and 'matter plan' appear duplicated in the trigger list, but this doesn't materially detract from quality.
| Dimension | Reasoning | Score |
|---|---|---|
Specificity | Lists multiple specific concrete actions: converting scope into a structured matter plan, phases, workstreams, milestones, dependencies, owner assignments, and matter setup decisions. These are concrete, domain-specific deliverables. | 3 / 3 |
Completeness | Clearly answers both 'what' (convert scope into structured matter plan with phases, workstreams, milestones, dependencies, owner assignments, matter setup decisions) and 'when' (explicit 'Use when...' clause plus a detailed 'Trigger on:' list with specific phrases). | 3 / 3 |
Trigger Term Quality | Excellent coverage of natural trigger terms including 'build a plan', 'project plan', 'what are the phases', 'who owns what', 'kickoff agenda', 'how do we sequence this', and domain-specific terms like 'task codes', 'rolling wave', 'matter setup'. These reflect how users would naturally phrase requests. | 3 / 3 |
Distinctiveness Conflict Risk | Highly distinctive with a clear niche in legal/professional services matter planning. Terms like 'matter plan', 'task codes', 'matter setup', and 'workstream plan' are domain-specific and unlikely to conflict with generic project management or other skills. | 3 / 3 |

Implementation
55%Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.
This skill is exceptionally thorough and actionable, with precise field schemas, clear workflows, and explicit validation checkpoints that would produce high-quality, consistent plan outputs. However, it is severely undermined by its length — the content is roughly 5-10x longer than necessary, with extensive prose explanations of planning philosophy, failure modes, and justifications that Claude does not need. The entire document is inline with no progressive disclosure to separate reference material from core instructions.
Suggestions
Extract domain knowledge sections (matter type phase patterns, common planning failures, standard plan fields) into separate reference files (e.g., PHASE_PATTERNS.md, PLAN_FIELDS.md) and link to them from the main skill with one-line descriptions.
Remove the explanatory prose about why each design decision matters (e.g., the multi-paragraph justification for Mode 5, the essay on why lawyers don't update plans) — Claude can follow instructions without being persuaded of their rationale.
Consolidate the 'Common Planning Failures' section into a concise checklist of anti-patterns (one line each) rather than multi-paragraph explanations of each failure mode.
Cut redundant content where the same point is made in multiple sections (e.g., owner naming requirements appear in Step 1, Step 4, and Common Planning Failures; plan maintenance issues appear in Mode 5 description and Common Planning Failures).
| Dimension | Reasoning | Score |
|---|---|---|
Conciseness | Extremely verbose at ~400+ lines. Contains extensive explanations of why things matter ('A plan that exists only in the partner's head is not a plan — it is an intention'), lengthy descriptions of common failures that read as essays rather than instructions, and repeated justifications for design decisions (e.g., the multi-paragraph explanation of why lawyers don't update plans in Mode 5 and again in Common Planning Failures). Much of the domain knowledge and failure mode content explains concepts an LLM can reason about without being told. | 1 / 3 |
Actionability | Highly actionable with specific field schemas for every plan component (workstream headers, task entries, milestone entries, dependency entries), exact column orders for workstream plan tables, concrete naming conventions (e.g., [MatterCode]-T-[sequential number]), explicit field mappings from intake to plan, and precise output requirements. The guidance is specific enough to produce consistent, structured outputs. | 3 / 3 |
Workflow Clarity | Clear 6-step sequential process with explicit validation checkpoints: Step 1 requires confirming scope baseline and owner names before proceeding (with a hard stop), Step 5 builds setup recommendations before finalizing, and Step 6 produces outputs in a defined sequence. The skill includes explicit gates ('Do not proceed to plan output until the user has responded'), feedback loops for Mode 5 (propose → confirm → produce), and phase gate decision points throughout. | 3 / 3 |
Progressive Disclosure | Monolithic wall of text with no references to external files. The domain knowledge sections (matter type phase patterns, common planning failures), standard plan fields, and communication rhythm content could easily be split into separate reference files. Everything is inline, making the skill extremely long and difficult to navigate. No external file references or clear navigation structure beyond section headers. | 1 / 3 |
