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 | $0.00085 | $0.01928 |
| Opus 5 | $0.00043 | $0.00964 |
| Sonnet 5 | $0.00017 | $0.00386 |
| Haiku 4.5 | $0.00009 | $0.00193 |
Grade A, and why
copywriting 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 13d 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 — 221 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Copywriting & Microcopy
Words are interface elements. They reduce confusion, build trust, and drive action. This skill helps you write copy for every surface of your product — from headlines to error messages.
If
ABOUT-ME.mdand/orMY-ICP.mdexist in the project root, read them before writing. Use ABOUT-ME.md for voice and tone — write like the founder. Use MY-ICP.md for message framing — speak to the customer's pain in their language. When both exist: the founder's voice delivers the customer's message.
Core Principles
- Clarity over cleverness. The user should never have to re-read a line.
- Write like a smart friend, not a corporation. Warm, direct, confident.
- Every word must earn its place. Cut ruthlessly.
- Benefits before features. "Save 4 hours a week" beats "Automated reporting."
- The best microcopy is invisible — it prevents the question before it's asked.
- Use the user's language, not your internal jargon.
- Specificity builds credibility. "Join 12,847 teams" beats "Join thousands."
Workflow
- [ ] Identify what you're writing (headline, CTA, error, empty state, etc.)
- [ ] Define the ONE job this copy has (inform, persuade, reassure, guide)
- [ ] Write a draft using the patterns below
- [ ] Review against the voice checklist
- [ ] Test: read it aloud. If it sounds stiff, rewrite.
Headlines
Formulas that work:
- [Desired outcome] without [pain point]: "Ship faster without breaking things"
- [Action verb] your [noun]: "Automate your workflows"
- The [noun] for [specific audience]: "The CRM for founders who hate CRMs"
- [Specific result] in [timeframe]: "Launch your landing page in 10 minutes"
- Stop [pain]. Start [gain]: "Stop chasing invoices. Start getting paid."
Tell AI:
Write 5 headline options for our [page type]:
- Product: [what it does]
- Audience: [who it's for]
- Main benefit: [what they get]
- Use these formulas: outcome without pain, specific result in timeframe, the X for Y
- Make each under 10 words
- Show the strongest option first with reasoning
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.

copywriting is a skill published in the GitHub repository whawkinsiv/solo-founder-skills (243 stars, last pushed 16d ago), licensed MIT. It adds 85 tokens to every session and 1,928 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
