Quality

Content

56%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 thorough, well-sequenced methodology guide with concrete formulas and validation checklists, undermined by verbosity and a broken example reference. The generic boilerplate sections and re-teaching of basic market-sizing concepts inflate the token budget without adding value Claude doesn't already have.

Suggestions

Remove the generic 'Use this skill when' / 'Do not use this skill when' / 'Instructions' boilerplate, which duplicates the description and adds no methodology value.

Delete or create the referenced examples/saas-market-sizing.md — the body points users to a file that does not exist in the bundle.

Move industry-specific considerations and presenting-for-investors/strategy sections into reference files to slim the SKILL.md overview.

DimensionReasoningScore

Conciseness

At ~420 lines the body is noticeably verbose: generic boilerplate ('Use this skill when' / 'Do not use this skill when' / 'Instructions' with 'Clarify goals... validate outcomes') and re-explanations of TAM/SAM/SOM basics that Claude already knows pad out otherwise useful methodology.

2 / 5

Actionability

Provides concrete formula templates (TAM = Sigma(Segment Size x Annual Revenue), SAM = TAM x Geographic % x Segment %) and worked numeric examples ($10B x 0.40 x 0.30 x 0.60 = $720M), giving mostly executable guidance with minor gaps.

4 / 5

Workflow Clarity

A clear six-step process with an explicit Validate-and-Triangulate step plus checklists (Red Flags, Common Mistakes to Avoid); not a full validate-fix-retry loop, but well sequenced with most checkpoints present.

4 / 5

Progressive Disclosure

Has section structure and one real, clearly signaled reference (references/data-sources.md exists), but the body inlines large blocks that could be separate files and references a non-existent examples/saas-market-sizing.md.

Description

81%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 trigger-rich, well-targeted description that excels at when-to-use signals and distinctiveness, but it describes the domain rather than the skill's concrete outputs, so the 'what' stays implied. The third-person framing ('This skill should be used when the user asks...') avoids first/second-person voice penalties.

Suggestions

Lead with a concrete 'what' clause in third person (e.g., 'Calculates TAM, SAM, and SOM using top-down, bottom-up, and value-theory methodologies') before the trigger list.

Trim the long quoted trigger chain into a tighter set of the most natural phrases to reduce verbosity while keeping coverage.

DimensionReasoningScore

Specificity

Names the domain (market sizing) and concrete actions ('calculate TAM', 'determine SAM', 'estimate SOM'), but these are framed as user trigger phrases rather than explicit capabilities of the skill, leaving the 'what' somewhat implied.

3 / 5

Completeness

The 'when' is exceptionally explicit ('when the user asks to...'), but the 'what' is only the domain label 'market sizing analysis' rather than a concrete statement of what the skill produces.

4 / 5

Trigger Term Quality

Comprehensive natural-language triggers a user would actually say ('size the market', 'what's the total addressable market', 'calculate market opportunity') with good synonym coverage across TAM/SAM/SOM.

5 / 5

Distinctiveness Conflict Risk

Highly specific niche (TAM/SAM/SOM market sizing) with distinctive trigger phrases that are unlikely to collide with other skills.
