Quality

Content

77%

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 a clear phased workflow and useful checklists, but it is verbose and monolithic — all content lives inline in SKILL.md with no progressive disclosure via reference files. Tightening framing prose and splitting the output template/frameworks into referenced files would lift the weaker dimensions.

Suggestions

Move the full Phase 5 output template and per-placement copy frameworks into a referenced file (e.g. references/output-template.md) and link to it from the body to improve progressive disclosure.

Trim the 'Core principle' framing paragraph and other opinionated preamble; keep only guidance Claude cannot derive itself.

Add an explicit self-validation step before saving the plan (e.g. 'verify every intake field is reflected in the output before writing the file').

Dimension	Reasoning	Score
Conciseness	The body is mostly efficient and actionable, but the framing paragraphs ('The biggest Meta Ads mistake startups make is boosting a post...') and the sheer length (~280 lines of tables) could be tightened; it is verbose though accurate.	2 / 3
Actionability	Provides concrete executable guidance throughout — specific web_search queries, copy-framework tables with char limits and examples, a full output template, and checklists — copy-paste ready rather than abstract.	3 / 3
Workflow Clarity	A clear Phase 0–5 sequence is paired with explicit checklists (Tracking Setup, Launch) and a Week 1–2 monitoring plan with an optimization feedback loop ('pause losers, scale winners').	3 / 3
Progressive Disclosure	The skill is well-organized into phases but is a single monolithic file with no bundle references; content that could be split out (the large output template, copy frameworks) is all inline, so it stays at the score-2 anchor.	2 / 3

Description

82%

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 specific, third-person, and well-scoped, naming concrete campaign-architecture actions and distinguishing itself from creative generation. Its main weakness is the absence of an explicit 'Use when...' trigger clause, which caps completeness at 2.

Suggestions

Add an explicit trigger clause, e.g. 'Use when the user asks to set up, structure, or plan a Meta/Facebook/Instagram ad campaign — not for generating creative assets.'

Include a couple more natural user phrasings (e.g. 'Facebook Ads', 'ad set structure') to broaden trigger coverage.

Dimension	Reasoning	Score
Specificity	Lists multiple concrete actions — 'generates audience targeting recommendations, ad set structure, copy framework per placement, and exports as a campaign brief or structured CSV' — matching the score-3 anchor for specific concrete actions.	3 / 3
Completeness	Clearly answers 'what' with concrete actions but lacks any explicit 'Use when...' trigger clause; per the rubric, a missing explicit trigger guidance caps completeness at 2.	2 / 3
Trigger Term Quality	Covers natural terms users would say — 'Meta Ads campaign builder', 'Facebook and Instagram', 'audience targeting', 'campaign brief', 'CSV' — with good variation across common phrasings.	3 / 3
Distinctiveness Conflict Risk	The explicit scope boundary 'Focused on campaign architecture, not creative generation' carves a clear niche unlikely to trigger for unrelated skills.	3 / 3
