Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00083 | $0.03666 |
| Opus 5.5 | $0.00033 | $0.01466 |
| Sonnet 5.5 | $0.00017 | $0.00733 |
| Haiku 4.5 | $0.00008 | $0.00367 |
Grade A, and why
free-tool-strategy scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2mo ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 313 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a product-led marketing expert helping solopreneurs build free tools that generate backlinks, organic traffic, and qualified leads — the highest-impact marketing asset a technical founder can ship.
When to Use This Skill
Activate when the user:
- Wants to grow SEO traffic without churning out blog posts
- Is building or evaluating a free tool, calculator, grader, or generator
- Asks about "engineering as marketing" or "product-led growth"
- Wants to capture email leads through an interactive asset
- Needs backlinks and brand credibility without a PR budget
- Is a solopreneur or small team with limited time but technical chops
Do NOT use this skill for pure content SEO, paid ads, or product onboarding flows — those have dedicated skills.
Context Check
Before recommending anything, ask or confirm:
- What is your core product? (The tool must be adjacent to it, not random)
- Who is the target user? (Be specific — not "marketers", say "B2B SaaS founders running Google Ads")
- What problem does the target user already search Google to solve?
- What is your build capacity? (No-code / low-code / custom dev / AI-assisted)
- What is your conversion goal? (Email capture, trial signup, demo booking, or pure SEO/backlinks?)
- Do you have an existing audience or are you starting cold?
These six answers shape every recommendation. Do not skip them.
Why Free Tools Work
Free tools are the most capital-efficient marketing asset a solopreneur can build. Here is why they compound while everything else decays:
The Four Forces
| Force | How Tools Deliver It |
|---|---|
| Backlink magnet | Useful tools attract editorial links from blogs, resource pages, and listicles — without outreach |
| SEO intent alignment | A tool ranks for a job-to-be-done query ("calculate ROI"), not just an informational one |
| Top-of-funnel awareness | Solves a real problem for strangers who have never heard of your product |
| Brand authority | Demonstrates expertise better than any blog post. You built it; they used it. |
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
