Quality

Content

93%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 content is lean, fully executable, and well-structured as an overview that delegates to a meta-skill and a one-level-deep recipe, with only a minor validation gap in the workflow keeping it from a perfect score across the board.

Dimension	Reasoning	Score
Conciseness	The body is lean — a copy-paste Quick Start and a tight numbered Execution order — with no padding or explanation of concepts Claude already knows; every line earns its place.	5 / 5
Actionability	Fully executable: concrete shell commands (npm install, deepline auth register/wait/status) and a specific step (invoke deepline-gtm via the Skill tool, read the recipe at a given relative path) that are copy-paste ready.	5 / 5
Workflow Clarity	A clear numbered 1-2-3 sequence with an auth-status checkpoint, but the only validation step is the auth check; there is no explicit verification after the recipe is read/executed, leaving a minor validation gap.	4 / 5
Progressive Disclosure	The SKILL.md acts as an overview with a single well-signaled, one-level-deep reference to ../deepline-gtm/recipes/build-tam.md gated by explicit routing conditions, with content appropriately split between this file and the recipe.	5 / 5
	Total	19 / 20 Passed

Description

66%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 names specific providers, giving it a clear niche, but it omits any "Use when..." trigger guidance, which caps completeness at 3 and leaves it slightly below the best examples.

Suggestions

Add a "Use when..." clause naming the natural trigger phrases (e.g., "Use when the user wants to build a TAM/lead list, source B2B accounts and contacts, or mentions Crustdata, Dropleads, or PDL.").

Include common synonyms such as "lead list", "prospect list", and "B2B contacts" to broaden trigger-term coverage.

Optionally mention downstream actions (enrich, deduplicate, segment) to round out coverage of the TAM-building process.

Dimension	Reasoning	Score
Specificity	Names the domain and several concrete actions — "Build a Total Addressable Market list by sourcing accounts and contacts" — plus specific providers (Crustdata, Dropleads, PDL), though coverage of the full TAM-building process (enrichment, dedup) is incomplete, keeping it below a 5.	4 / 5
Completeness	Has a clear "what" (build a TAM list by sourcing accounts/contacts from named providers) but no "Use when..." clause or equivalent trigger guidance, so per the rubric completeness is capped at 3.	3 / 5
Trigger Term Quality	Good natural-term coverage ("Total Addressable Market", "accounts and contacts", named providers) that users would actually say, but misses common synonyms like "lead list", "prospect list", or "B2B contacts".	4 / 5
Distinctiveness Conflict Risk	The named providers (Crustdata, Dropleads, PDL) give it a distinct niche with minimal conflict risk, though "build a TAM / source contacts" could still overlap with broader lead-generation or GTM skills.	4 / 5
