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

72%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: concise, table-driven, with concrete decision thresholds and exemplary progressive disclosure to two real reference files. Its main weakness is workflow clarity — the content reads as a reference knowledge base rather than a sequenced process, so an agent must infer the order of operations.

Suggestions

Add an explicit numbered workflow near the top (e.g., 1. Gather business context → 2. Ideate from pain points → 3. Validate with the scorecard → 4. Choose gating and build vs. buy → 5. Scope the MVP) so the section order becomes an operational sequence rather than an implied one.

Tie the Evaluation Scorecard into the workflow as an explicit decision gate — state what to do at each band (e.g., '<15: stop and revisit ideation; 15-24: refine the weakest factors before building') so the checkpoint has follow-through.

Trim low-information lines (e.g., 'Genuinely useful (people reference them)' under Link Building and the 'You are an expert...' opener) to tighten token efficiency.

DimensionReasoningScore

Conciseness

Mostly lean — tables, terse bullets, and benchmark citations rather than prose — but a few lines pad without informing ("Genuinely useful (people reference them)") and the role-play opener ("You are an expert in engineering-as-marketing strategy") adds little; matches anchor 4 (efficient with minor trims possible), not 5.

4 / 5

Actionability

For an instruction-only skill the guidance is largely concrete: a gating-options tradeoff table, named no-code tools ("Outgrow, Involve.me, Typeform, Tally, Bubble, Webflow"), a numeric decision threshold ("25+ Strong candidate | 15-24 Promising | <15 Reconsider"), a defined MVP scope, and named case benchmarks. Score 4 rather than 5 because some ideation guidance remains high-level questioning rather than executable direction.

4 / 5

Workflow Clarity

The sections imply a flow (assessment → ideation → validation → lead capture → build → MVP → scorecard) but never sequence it as an explicit multi-step workflow, and the evaluation scorecard checkpoint is not tied into that flow — matching anchor 3 (sequence present but checkpoints missing or implicit). Not 4 because there is no explicit step order or decision gate connecting sections.

3 / 5

Progressive Disclosure

A clean overview body with two real, one-level-deep reference files, both clearly signaled with descriptive labels: "See [references/tool-types.md](references/tool-types.md)" and "For named case benchmarks (Unsplash, HubSpot Website Grader, Moz, Buffer, Shopify) with real conversion numbers: See [references/tool-benchmarks.md](references/tool-benchmarks.md)." Both files exist in the bundle; matches anchor 5.

Description

95%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.

An exemplary description: third-person voice, explicit what-and-when with concrete trigger phrases, a natural synonym-rich trigger list, and clear boundary guidance to a sibling skill. Only a minor specificity gap keeps it from full marks.

DimensionReasoningScore

Specificity

Names the domain and three concrete actions ("plan, evaluate, or build a free tool for marketing purposes — lead generation, SEO value, or brand awareness"), matching the anchor for several specific actions with minor gaps; not a 5 because coverage of capabilities is good but not exhaustive.

4 / 5

Completeness

Explicitly answers both what ("plan, evaluate, or build a free tool for marketing purposes — lead generation, SEO value, or brand awareness") and when ("Also use when the user mentions..." and "Use this whenever someone wants to build something useful and give it away") with concrete trigger phrases, matching the anchor-5 example.

5 / 5

Trigger Term Quality

Comprehensive coverage of natural phrases users would actually say, including synonyms and specific variants: "engineering as marketing," "free tool," "marketing tool," "calculator," "generator," "lead gen tool," "build a tool for leads," "ROI calculator," "grader tool," "audit tool," "should I build a free tool," and "tools for lead gen."

5 / 5

Distinctiveness Conflict Risk

Clear niche (marketing/lead-generation purpose) with distinct triggers and explicit boundary guidance ("For downloadable content lead magnets (ebooks, checklists, templates), see lead-magnets"); generic single-word triggers like "calculator" pose only minimal conflict risk given the consistent marketing framing.
