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.

What it costs to keep this loaded
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 | $0.00157 | $0.03083 |
| Opus 5 | $0.00078 | $0.01541 |
| Sonnet 5 | $0.00031 | $0.00617 |
| Haiku 4.5 | $0.00016 | $0.00308 |
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 10d 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 — 327 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Free Tool Strategy (Engineering as Marketing)
Purpose
Free tools are permanent acquisition assets. Build a calculator, checker, generator, or grader that your target audience actively searches for. It ranks in Google, gets shared, and funnels users to your paid product. One tool can drive more signups than months of content.
Reads
brand/audience.md— Personas, daily workflow, pain pointsbrand/keyword-plan.md— Search volume data for tool-related queriesbrand/positioning.md— Positioning angles to connect tool → productbrand/creative-kit.md— Brand colors, fonts for tool landing page
On Activation
- Read
brand/audience.md,brand/keyword-plan.md,brand/positioning.md,brand/creative-kit.md. - If any file is missing, note what's unavailable. The skill works at zero context — ask the user directly for missing info in Step 1.
- Pre-fill persona details, keyword data, and positioning angles from whatever brand/ files exist. Only ask for what's genuinely unknown.
Why these files matter: audience.md tells you whose pain to solve (without this, tools target the wrong users). keyword-plan.md gives search volume data so you don't build tools nobody searches for. positioning.md connects the free tool to the paid product (without this connection, traffic doesn't convert). creative-kit.md ensures the tool landing page matches the brand.
Workflow
Step 1: Identify Audience Workflow Pain Points
If brand/audience.md exists, extract the primary persona and their pain points — skip the interview below and go straight to Step 2 with that data. If not, map the target audience's daily workflow and find friction:
Persona: [Role/Title]
Daily workflow:
1. [Task] -> Pain: [what's annoying about this]
2. [Task] -> Pain: [what's tedious/manual]
3. [Task] -> Pain: [what requires expensive tools]
4. [Task] -> Pain: [what they currently use spreadsheets for]
5. [Task] -> Pain: [what they google repeatedly]
Best free tool candidates solve pains that are:
- Recurring (done weekly or more)
- Currently solved with manual effort or spreadsheets
- Searchable ("X calculator", "X generator", "X checker")
- Completable in one session (not ongoing SaaS)
- Adjacent to your paid product's value prop
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
