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 | $0.00684 | $0.00684 |
| Opus 5 | $0.00342 | $0.00342 |
| Sonnet 5 | $0.00137 | $0.00137 |
| Haiku 4.5 | $0.00068 | $0.00068 |
Grade A, and why
solopreneur-skills CLAUDE.md 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 12d 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 — 67 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLAUDE.md
Instructions for Claude Code instances working in this repo. For the full authoring spec see AGENTS.md; for contribution flow see CONTRIBUTING.md. If this file disagrees with either, AGENTS.md wins.
Repository purpose
Open-source Claude skills for solopreneur marketing — SEO, CRO, copywriting, email, pricing, growth, and analytics. Each skill packages opinionated, research-backed guidance a founder can run without hiring a specialist.
Skill structure
Every skill lives at skills/<skill-name>/SKILL.md with YAML frontmatter:
---
name: skill-name
description: One sentence on when to use this skill, with trigger phrases. 50–1024 characters.
metadata:
version: 1.0.0
author: Your Name
license: MIT
---
The filename is always SKILL.md (uppercase). The folder name is kebab-case and matches the name field.
When adding skills
- Read
CONTRIBUTING.mdend-to-end before writing. - Check existing skills in
skills/for overlap — prefer extending a sibling skill over creating a near-duplicate. - Research before writing: Reddit threads, practitioner blogs, primary frameworks. Every non-obvious claim should be traceable to a source.
- Draft the skill, then run the validator.
When editing skills
- Preserve the
metadata.versionfield in frontmatter. - Bump version on meaningful content changes (not typos): patch for fixes, minor for added sections, major for reorganization.
- Log the change in
VERSIONS.md. - Run the validator before committing.
Style rules
- Target under 500 lines per
SKILL.md. If you are over, you are padding. - Plain markdown. Minimal emoji — none in body copy, sparingly in section headers only if the skill already uses them.
- Banned phrases (single source of truth — enforced by the validator as warnings):
delve,leverage,unlock,supercharge,game-changer,in today's landscape,ever-evolving,navigate the complexities,robust,seamless,at the end of the day. - Cite sources inline with the year:
(Baymard, 2024),(Nielsen Norman, 2023). - Every skill must include these three sections:
Common Mistakes,Contrarian Takes,Related Skills. - Every skill must end with the footer:
*Generated using the <skill-name> skill from Solopreneur Skills*.
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.
