Quality

Content

82%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.

The skill body is highly actionable with a concrete template and worked example, and is well-structured for a single-file skill. Minor gains are available from deduplicating the bad-hook/avoid examples and adding an explicit review-against-checklist step.

Suggestions

Dedupe the repeated 'bad hook' / 'Avoid' examples between the Hook section and 'Common Mistakes' to tighten conciseness.

Add an explicit post-draft checkpoint (e.g. 'Before sending, re-read against Common Mistakes and confirm every line is company-specific') to strengthen workflow clarity.

Consider moving the full worked example to a references/ file to reduce SKILL.md length and improve progressive disclosure.

DimensionReasoningScore

Conciseness

The body is domain craft rather than concepts Claude already knows and is mostly efficient, though 'bad hook' examples and 'Avoid' lists recur in both the Hook section and 'Common Mistakes', which could be trimmed.

4 / 5

Actionability

It provides a complete fill-in template, concrete rules, a fully worked example email, and a copy-paste output format — fully executable guidance covering the common cases.

5 / 5

Workflow Clarity

A clear sequence (research → template → length check → code-block output) is present with a 'Common Mistakes' self-check, but there is no explicit post-draft validation checkpoint.

4 / 5

Progressive Disclosure

Single well-organized file with clear section headers and no bundle files; no external references are needed, but at ~213 lines it exceeds the simple-skill threshold that would allow a 5.

Description

61%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.

The description is concrete and niche-specific but omits explicit 'when to use' trigger guidance, which the rubric penalizes. It is stronger on distinctiveness than on completeness.

Suggestions

Add a 'Use when…' clause with concrete triggers, e.g. 'Use when the user asks to write a cold email, reach out to a hiring manager, or send an intro email about an unreferred job opening.'

Include the natural trigger synonyms already in the body ('cold email', 'reach out', 'intro email', 'recruiter') directly in the description for better trigger-term coverage.

DimensionReasoningScore

Specificity

Names the domain and one concrete action ('Write personalized cold outreach emails') plus concrete targets ('hiring managers and founders'), but does not list several specific actions, so it stops at anchor 3 rather than 4.

3 / 5

Completeness

It clearly states what the skill does but has no 'Use when…' or equivalent trigger guidance, and the rubric caps completeness at 3 when the 'when' is missing.

3 / 5

Trigger Term Quality

Includes natural phrases a user would say ('cold outreach emails', 'hiring managers', 'founders', 'personalized'), but misses common variations like 'cold email', 'reach out', 'intro email', and 'recruiter' that appear only in the body.

4 / 5

Distinctiveness Conflict Risk

The cold-outreach-to-hiring-managers/founders niche is mostly distinct with low conflict risk, though there is minor overlap with general professional-email skills.
