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 a thorough, well-sequenced, and actionable market-sizing workflow with strong validation checkpoints. Its main weakness is conciseness, due to redundant boilerplate sections, and the lack of any progressive-disclosure structure splitting the long monolithic document.

Suggestions

Remove the generic 'Instructions' section and the duplicative 'What This Command Does' list, since they restate the detailed steps that follow.

Trim the templated 'Use this skill when / Do not use this skill when' boilerplate, which adds tokens without domain-specific value.

Consider moving the lengthy 9-section report template and per-business-model TAM formulas into a reference file (e.g. references/report-template.md) to improve progressive disclosure and reduce the SKILL.md footprint.

Dimension	Reasoning	Score
Conciseness	The core step-by-step methodology is useful, but the body is padded with redundant boilerplate such as the generic 'Instructions' bullets and the 'What This Command Does' list that duplicates the later detailed steps, fitting the 'mostly efficient but includes some unnecessary explanation' anchor.	2 / 3
Actionability	The skill provides concrete formulas (TAM = Σ (Segment Size × ACV); SAM = TAM × Geographic % × Product Fit % × Market Readiness %), specific SOM percentages (Year 3: 2-3%, Year 5: 4-6%), named data sources, and a full 9-section report template, giving actionable, copy-ready guidance.	3 / 3
Workflow Clarity	The process is sequenced across nine explicit steps with validation checkpoints, including the 'If variance > 30%, investigate and explain differences' feedback loop and a dedicated 'Validation and Sanity Checks' section, matching the clear-sequence-with-explicit-validation anchor.	3 / 3
Progressive Disclosure	The body is well-organized into sections but is a monolithic single file with no bundle files in references/, scripts/, or assets/ and no one-level-deep references, so content that could be split out remains inline, fitting the 'some structure but content that should be separate is inline' anchor.	2 / 3
	Total	10 / 12 Passed

Description

57%

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 to a clear niche and names the core deliverables, but it lacks an explicit 'Use when' trigger clause and only offers partial coverage of natural trigger terms. It is solid but not exemplary.

Suggestions

Add an explicit trigger clause, e.g. 'Use when sizing a market, estimating TAM/SAM/SOM, or preparing a market opportunity analysis for investors.'

Broaden trigger terms to include natural phrasings users actually say, such as 'market sizing', 'TAM calculation', and 'addressable market'.

Consider listing the concrete outputs (bottom-up and top-down TAM, SAM filters, SOM projections) to lift specificity from a single action to multiple concrete actions.

Dimension	Reasoning	Score
Specificity	The phrase 'Generate comprehensive market opportunity analysis with TAM/SAM/SOM calculations' names the domain and the key deliverables, but it is a single action phrase rather than a list of multiple distinct concrete actions, matching the 'names domain and some actions, but not comprehensive' anchor.	2 / 3
Completeness	The description clearly states what the skill does but provides no 'Use when...' clause or equivalent explicit trigger guidance, so completeness is capped at 2 per the judging guidelines.	2 / 3
Trigger Term Quality	'market opportunity analysis' and 'TAM/SAM/SOM' are relevant natural terms, but common variations a user might say such as 'market sizing' or 'TAM calculation' are missing, fitting the 'some relevant keywords but missing common variations' anchor.	2 / 3
Distinctiveness Conflict Risk	The niche of 'market opportunity analysis with TAM/SAM/SOM calculations' is a clear, specialized domain with distinct terminology that is unlikely to trigger for unrelated skills.	3 / 3
	Total	9 / 12 Passed
