free-tool-strategy

When the user wants to build a free tool for marketing — lead generation, SEO value, or brand awareness. Use when they mention 'engineering as marketing,' 'free tool,' 'calculator,' 'generator,' 'checker,' 'grader,' 'marketing tool,' 'lead gen tool,' 'build something for traffic,' 'interactive tool,' or 'free resource.' Covers idea evaluation, tool design, and launch strategy. For pure SEO content strategy (no tool), use seo-audit or content-strategy instead.

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, actionable strategy skill with concrete frameworks, templates, and measurement guidance across three clear modes. Its main weakness is progressive disclosure: the bundled references/launch-playbook.md is orphaned, with no link or mention from the SKILL.md overview, so Claude would never discover it.

Suggestions

Add a clearly signaled link to references/launch-playbook.md from the relevant section (e.g., 'Mode 3: Launch and Measure') so the bundled launch playbook is discoverable from SKILL.md.

Tighten the opening persona paragraph and occasional rhetorical asides to improve token efficiency without losing the directive tone.

Add an explicit validation checkpoint inside the Mode 2 (Design) workflow — e.g., confirm keyword validation has passed before proceeding to design — to match the gating rigor already present in Mode 1.

Dimension	Reasoning	Score
Conciseness	Mostly efficient — tables, checklists, and concrete frameworks dominate, and it avoids explaining basic marketing concepts Claude already knows — but the opening persona paragraph and a few rhetorical flourishes ('you've designed a lead form, not a tool') could be trimmed.	4 / 5
Actionability	Highly actionable instruction content: a 6-factor scoring rubric with numeric 1–5 anchors and a scoring guide, a tool-types table with complexity ratings, concrete gating thresholds ('Max 3 inputs', 'First gate: Email only'), a copy-paste landing-page structure, an executable SoftwareApplication schema JSON block, a measurement table with specific tools and 90-day targets, and a runnable script invocation.	5 / 5
Workflow Clarity	Each of the three modes has a clearly sequenced numbered workflow, with a validation gate in Mode 1 ('Validate with keyword data before committing engineering time') and a measure-then-iterate feedback loop in Mode 3, plus proactive-trigger flags; validation checkpoints are present but not deeply woven into every step, leaving minor gaps versus the score-5 anchor.	4 / 5
Progressive Disclosure	The body is well-sectioned and clearly signals references/tool-types-guide.md (line 83) and scripts/tool_roi_estimator.py (lines 225, 251), but references/launch-playbook.md is a bundle file that is never linked or surfaced from the overview — a navigation gap where a discoverable reference is invisible to a reader of SKILL.md.	3 / 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.

A strong, well-structured description that clearly states what the skill does, when to trigger it via an extensive natural-phrase list, and where its boundaries lie relative to sibling skills. The only minor gap is that the named actions are lifecycle-level rather than granular verbs.

Dimension	Reasoning	Score
Specificity	Lists several concrete action areas — 'idea evaluation, tool design, and launch strategy' plus the goals 'lead generation, SEO value, or brand awareness' — but the actions are high-level lifecycle phases rather than the granular verbs in the score-5 anchor, leaving minor coverage gaps.	4 / 5
Completeness	Explicitly answers both 'what' (build a free marketing tool; covers idea evaluation, tool design, launch strategy) and 'when' (a long 'Use when they mention…' trigger list), mirroring the score-5 anchor structure.	5 / 5
Trigger Term Quality	Comprehensive natural-phrase coverage with synonyms — 'engineering as marketing,' 'free tool,' 'calculator,' 'generator,' 'checker,' 'grader,' 'marketing tool,' 'lead gen tool,' 'build something for traffic,' 'interactive tool,' 'free resource' — matching the score-5 anchor's breadth including common variations.	5 / 5
Distinctiveness Conflict Risk	Clear niche (free marketing tools) with distinct triggers and explicit boundary guidance — 'For pure SEO content strategy (no tool), use seo-audit or content-strategy instead' — minimizing conflict with adjacent skills.	5 / 5
	Total	19 / 20 Passed
