Quality

Content

92%Weight 40%Scale 1-5

Reviews the quality of instructions and guidance provided to agents. Good implementation is clear, handles edge cases, and produces reliable results.

A tight, well-structured skill body: concrete quick start with expected output, grounding anti-patterns, and a verification checklist, all at minimal token cost. The only notable gap is that the tool invocation notation and the session-summary rendering case are described rather than fully exemplified.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's competence: no background explanation, every section (Why, Workflow, Anti-patterns, Checklist) earns its place. It matches the 'every token earns its place' anchor; the only candidate trim is the one-sentence preamble restating the user's goal.

5 / 5

Actionability

It gives a concrete tool call with limit, a realistic expected-output sample, and an exact presentation format (id first 8 chars, reverse-chronological, per-session observation counts). It sits just below fully executable because the `memory_sessions { "limit": 20 }` notation is conceptual rather than copy-paste syntax, and the session-summary rendering case (step 5) is not exemplified.

4 / 5

Workflow Clarity

Five clearly sequenced steps plus a grounding rule ("An empty history is a real answer") and a Checklist that acts as explicit verification against invented data. This is a simple, read-only, single-purpose skill, so the simple-skill exception applies and the single workflow is unambiguous.

5 / 5

Progressive Disclosure

The skill is short and needs no bundle files (none exist), and its sections are well organized with clear headers. The one external reference — ../_shared/TROUBLESHOOTING.md — is clearly signaled, one level deep, and placed under Troubleshooting, matching the simple-skill guideline for a 5.

Description

86%Weight 40%Scale 1-5

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 with an explicit Use-when clause and excellent natural trigger phrases. The main weakness is specificity: it describes a single capability (showing a timeline) without enumerating what the presentation includes or any additional capabilities.

DimensionReasoningScore

Specificity

The description names the domain and one concrete action — "Show what happened in recent past sessions on this project as a clean timeline" — but does not list several specific capabilities, so it falls short of the 'several specific actions' anchor at 4 while exceeding the minimal-action anchor at 2.

3 / 5

Completeness

It explicitly answers what ("Show what happened in recent past sessions... as a clean timeline") and when ("Use when the user asks..." with concrete quoted trigger phrases), mirroring the anchor-5 example structure.

5 / 5

Trigger Term Quality

It quotes the natural phrases users would actually say — "what did we do last time", "session history", "past sessions" — plus "overview of previous work", giving comprehensive synonym coverage for this domain. It clearly matches the comprehensive anchor rather than the 'a few natural terms missing' anchor at 4.

5 / 5

Distinctiveness Conflict Risk

The session-history niche with quoted trigger phrases is mostly distinct, but "or wants an overview of previous work" is broad enough to overlap with recap/summary-style skills. Minor overlap risk places it at 4 rather than the minimal-conflict anchor at 5.
