Quality

Content

78%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 well-organized, lean instruction skill that points cleanly to a real one-level-deep reference bundle and gives concrete, specific writing guidance. The main gaps are minor redundancy across sections and the absence of a full inline example email.

Suggestions

Add one complete short example email inline (e.g., an Observation→Problem→Proof→Ask sample) so the most common case is copy-paste-ready without opening a reference.

De-duplicate the 'What to Avoid' list with the 'Voice & Tone' anti-patterns so each avoidance item appears once.

DimensionReasoningScore

Conciseness

The body is lean and assumes Claude's intelligence without over-explaining basics, but a few items are repeated across sections (e.g., 'I hope this email finds you well' appears in both Voice & Tone and What to Avoid), so it sits just below the fully-trimmed 5 anchor.

4 / 5

Actionability

Concrete, specific guidance is given — named framework shapes with mini-examples, subject-line rules (2-4 words, lowercase), follow-up cadence (3-5 emails, increasing gaps) — but no complete copy-paste-ready example email is shown inline, leaving minor gaps versus the 5 anchor.

4 / 5

Workflow Clarity

A clear sequence exists (check product-marketing context → gather the 5 situation inputs → write → gut-check via the Quality Check list) with a final validation checkpoint, though the mid-process steps are loosely defined rather than tightly gated.

4 / 5

Progressive Disclosure

The body is a clear overview with well-signaled one-level-deep markdown links to references/ (personalization.md, frameworks.md, subject-lines.md, follow-up-sequences.md, benchmarks.md), all of which exist as real files, and a consolidated 'Data & Benchmarks' navigation section — matching the 5 anchor.

Description

96%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, specific description with concrete capabilities, natural trigger terms, and explicit 'Use when' guidance covering both what and when. Only minor distinctiveness overlap with sibling copywriting/email skills keeps it from a perfect mark.

DimensionReasoningScore

Specificity

The description lists multiple concrete actions — 'Write B2B cold emails and follow-up sequences', 'personalized opening lines, subject lines, CTAs, and multi-touch follow-up sequences' — giving comprehensive coverage of the skill's capabilities, matching the 5-anchor example.

5 / 5

Completeness

It explicitly answers both 'what' (write B2B cold emails and follow-up sequences that earn replies) and 'when' via a concrete 'Use when creating outbound prospecting emails, SDR outreach...' trigger clause, matching the 5-anchor example.

5 / 5

Trigger Term Quality

Natural user-facing terms are well covered with synonyms: 'B2B cold emails', 'outbound prospecting emails', 'SDR outreach', 'subject lines', 'CTAs', 'follow-up sequences' — phrases a user would actually say when needing this skill.

5 / 5

Distinctiveness Conflict Risk

The niche is clear — cold outbound/SDR outreach with distinctive triggers — but there is minor overlap risk with closely related copywriting or general email skills, placing it just below the fully-distinct 5 anchor.
