free-tools

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," "free resource," "ROI calculator," "grader tool," "audit tool," "should I build a free tool," or "tools for lead gen." Use this whenever someone wants to build something useful and give it away to attract leads or earn links. For downloadable content lead magnets (ebooks, checklists, templates), see lead-magnets.

Quality

Content

75%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-organized, lean strategy skill with a real one-level-deep reference, concrete decision tables, named tool options, and an explicit evaluation scorecard that acts as a decision gate. Its main gaps are the absence of example deliverables or output formats that would make the guidance fully executable, and a workflow that is implied by section ordering rather than stated explicitly.

Suggestions

Actionability: add one brief worked example of the expected deliverable (e.g., a filled-in evaluation scorecard or a sample tool concept brief) so Claude knows exactly what artifact to produce for a plan or evaluate request.

Workflow clarity: state the end-to-end process explicitly as numbered phases (assess context → ideate → validate → decide build/buy → scope MVP → score and recommend) instead of relying on section ordering to imply the sequence.

Progressive disclosure: move the detail-heavy sections (gating option trade-offs, per-industry concept examples already in tool-types.md territory) into the reference file, keeping SKILL.md to the overview and decision rules.

DimensionReasoningScore

Conciseness

The body is dominated by lean bullet fragments and tables with no explanations of concepts Claude already knows, matching 'efficient; minor instances of over-explanation that could be trimmed' — e.g., the role preamble ("You are an expert in engineering-as-marketing strategy…") and generic principle lines like "Related to what you sell" could be tightened. Not 5 because those minor padded spots exist; not 3 because there is no genuinely unnecessary explanation or verbosity block.

4 / 5

Actionability

For an instruction-only strategy skill, the guidance is mostly concrete and executable: a tool-type taxonomy table, named no-code options ("Outgrow, Involve.me, Typeform, Tally, Bubble, Webflow"), an explicit MVP scope with a skip list ("Account creation, saving results, advanced features…"), and an 8-factor scorecard with numeric thresholds. It falls short of 5 because some guidance stays high-level ("Natural path from tool to product," "How can you be 10x better?") and there are no example deliverables, prompts, or output formats showing what Claude should actually produce.

4 / 5

Workflow Clarity

A clear sequence is present — numbered context gathering ("Before designing a tool strategy, understand: 1. Business Context… 2. Goals… 3. Resources…") leading through ideation, validation, lead capture, build-vs-buy, MVP scoping, and an explicit decision gate in the scorecard ("**25+**: Strong candidate | **15-24**: Promising | **<15**: Reconsider"). Matches 'clear sequence with most checkpoints present; minor validation gaps.' Not 5 because the phases are implied by section order rather than stated as an explicit end-to-end workflow with feedback loops; not 3 because the scorecard threshold gate is an explicit checkpoint, not an implicit one.

4 / 5

Progressive Disclosure

Scored against the actual bundle (one real file, references/tool-types.md): the reference is clearly signaled ("**For detailed tool types and examples**: See [references/tool-types.md](references/tool-types.md)"), exactly one level deep, and the inline Tool Types Overview table appropriately summarizes while deferring detail. This fits 'good structure; most content is appropriately placed; minor organization gaps' — not 5 because the body still carries several detail-weight sections inline (the full gating table, link-building rationale, scorecard) with only one bundle file to distribute depth.

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 clearly states what the skill does and when to use it, with an unusually thorough set of natural trigger phrases and explicit disambiguation from the adjacent lead-magnets skill. The only weakness is that a few of its trigger terms (calculator, generator, free resource) are generic enough to risk firing on non-marketing build requests.

DimensionReasoningScore

Specificity

"plan, evaluate, or build a free tool for marketing purposes — lead generation, SEO value, or brand awareness" names several specific actions and their purposes, matching the 'lists several specific actions; minor gaps in coverage' anchor. Not 5 because the actions (plan/evaluate/build) are verbs of engagement rather than a fully comprehensive enumeration of capabilities.

4 / 5

Completeness

It explicitly answers both what ("plan, evaluate, or build a free tool for marketing purposes") and when ("Use when the user wants to… Also use when the user mentions… Use this whenever someone wants to…"), with concrete trigger phrases, directly matching the anchor for clearly and explicitly answering both. It also disambiguates against lead-magnets for downloadable content.

5 / 5

Trigger Term Quality

The description covers an extensive set of natural phrases users would actually say: "engineering as marketing," "free tool," "marketing tool," "calculator," "generator," "interactive tool," "lead gen tool," "build a tool for leads," "free resource," "ROI calculator," "grader tool," "audit tool," "should I build a free tool," and "tools for lead gen." This matches the 'comprehensive coverage of natural terms including synonyms' anchor; no common variation is obviously missing.

5 / 5

Distinctiveness Conflict Risk

The engineering-as-marketing niche is distinct and the explicit pointer to lead-magnets handles the closest boundary. However, bare generic triggers like "calculator," "generator," and "free resource" could plausibly fire when a user simply wants a calculator or generator built with no marketing intent — a minor overlap risk with general dev/build requests, so it fits 'mostly distinct; minor overlap risk' rather than the minimal-conflict anchor 5.
