free-tool-strategy

When the user wants to plan, evaluate, or build a free tool for marketing purposes — lead generation, SEO value, or brand awareness. Also use when the user mentions "engineering as marketing," "free tool," "marketing tool," "calculator," "generator," "interactive tool," "lead gen tool," "build a tool for leads," or "free resource." This skill bridges engineering and marketing — useful for founders and technical marketers.

Quality

Content

78%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 well-structured strategy skill: lean, table-driven, and appropriately split between the SKILL.md overview and a single well-signaled reference file. The main gaps are the lack of an explicitly ordered consultation workflow and minor duplication between the inline tool-types table and the reference file.

Suggestions

State the consultation order explicitly at the top (e.g., 1. Assess context → 2. Ideate → 3. Validate against criteria → 4. Score with the scorecard → 5. Define MVP scope), and fold the Task-Specific Questions into the assessment step so the flow is unambiguous.

Trim the Tool Types Overview table in SKILL.md to type + one-line purpose, leaving examples and 'Best for' detail entirely to references/tool-types.md to remove the duplicated column.

Add one brief worked example of applying the Evaluation Scorecard to a concrete tool idea (e.g., an ROI calculator with factor ratings and total) so the rating guidance is directly executable.

DimensionReasoningScore

Conciseness

The body is efficiently written — dense tables, short bullets, and no padding explaining concepts Claude already knows, matching the 'efficient; minor instances that could be trimmed' anchor. It is not a 5 because the Tool Types Overview table duplicates the 'Best for' column of references/tool-types.md, and phrases like "Free tools attract links because..." spell out reasoning that could be tightened; it is well above anchor 3's 'noticeably unnecessary explanation.'

4 / 5

Actionability

Guidance is mostly executable for an instruction-only skill: a scored evaluation rubric with numeric thresholds ("25+: Strong candidate | 15-24: Promising | <15: Reconsider"), concrete keyword patterns ("[thing] calculator", "free [tool type]"), named no-code tools, and an explicit MVP/skip list — matching the 'mostly executable guidance with minor gaps' anchor. It is not a 5 because several sections stay at the advisory level (e.g., "Show preview of what they'll get") without a concrete worked example of applying the scorecard.

4 / 5

Workflow Clarity

The sections form a coherent consultation sequence (Initial Assessment → Ideation → Validate the Idea → Lead Capture/SEO considerations → Build vs. Buy → MVP Scope → Evaluation Scorecard) with two implicit checkpoints (validation criteria and the scorecard), fitting the 'clear sequence with most checkpoints present; minor validation gaps' anchor. It is not a 5 because the order is implicit in section layout rather than stated as an explicit step sequence, and the 'Task-Specific Questions' section appears after the evaluation step without integration; it clearly exceeds anchor 3, where the sequence is present but checkpoints are missing.

4 / 5

Progressive Disclosure

SKILL.md acts as a proper overview: detail (per-type examples and industry-specific concepts) lives in references/tool-types.md, referenced once with a well-signaled one-level-deep link ("For detailed tool types and examples: See [references/tool-types.md]"), and the file exists and matches what the link promises. The overview table plus single deep-dive reference matches the top anchor exactly.

Description

91%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 strong description: it explicitly answers both what the skill does and when to use it, with an extensive set of natural trigger phrases and a clear niche. Minor improvements possible: qualify broad trigger nouns like "calculator" with marketing context, and trim the audience filler sentence.

DimensionReasoningScore

Specificity

The description lists several specific actions ("plan, evaluate, or build a free tool") along with concrete goals ("lead generation, SEO value, or brand awareness"), matching the 'several specific actions; minor gaps' anchor. It is not a 5 because the actions are generic strategy verbs without concrete deliverables, and the trailing sentence ("bridges engineering and marketing — useful for founders and technical marketers") is light filler; it exceeds anchor 3, which expects only 1-2 concrete actions.

4 / 5

Completeness

Both 'what' ("plan, evaluate, or build a free tool for marketing purposes — lead generation, SEO value, or brand awareness") and 'when' ("When the user wants to... Also use when the user mentions...") are explicitly and clearly stated with concrete trigger phrases, matching the top anchor. A 4 would require the 'when' to be less explicit, but here trigger guidance is fully explicit.

5 / 5

Trigger Term Quality

Nine quoted natural trigger phrases are provided ("engineering as marketing," "free tool," "calculator," "generator," "lead gen tool," "build a tool for leads," "free resource"), covering synonyms and colloquial variations a user would plausibly say — this matches the comprehensive-coverage anchor. It is not below 5 because the term set spans the concept name, noun forms, and intent phrasings; there is no clearly missing common variant.

5 / 5

Distinctiveness Conflict Risk

The niche (engineering-as-marketing free tools) is fairly distinct with dedicated triggers like "engineering as marketing" and "lead gen tool," but bare terms like "calculator" and "generator" could fire on unrelated build requests, giving minor overlap risk per the anchor 4 example. It is not a 5 because those generic nouns are not qualified (e.g., 'for marketing') in the trigger list; it is not a 3 because the overall domain framing strongly disambiguates.
