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 | $0.01049 | $0.01049 |
| Opus 5 | $0.00524 | $0.00524 |
| Sonnet 5 | $0.00210 | $0.00210 |
| Haiku 4.5 | $0.00105 | $0.00105 |
Grade A, and why
solo-founder-toolkit 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 6d 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.

Solo Founder Toolkit
A Claude Code plugin designed for solo founders, indie hackers, and small teams who are shipping fast and iterating quickly.
CRITICAL: Always Use Available Skills and Agents
Before doing ANY task, check if a skill or agent exists for it and use it.
This is a plugin development project. The skills and agents listed below exist specifically to help build plugin components. You MUST use them proactively - don't wait to be asked.
Mandatory Skill/Agent Usage Rules
When creating skills → Use skill-development skill FIRST
When creating agents → Use agent-development skill FIRST
When creating commands → Use command-development skill FIRST
When creating hooks → Use hook-development skill FIRST
When adding MCP integration → Use mcp-integration skill FIRST
When adding plugin settings → Use plugin-settings skill FIRST
When scaffolding plugin structure → Use plugin-structure skill FIRST
After creating/modifying components:
- Use
skill-revieweragent to validate skills - Use
plugin-validatoragent to validate overall plugin structure
Why this matters: These tools exist to prevent mistakes and follow best practices. Not using them wastes time and creates technical debt.
Plugin Location
All plugin components live in: plugins/solo-founder-toolkit/
Target Audience
This toolkit is built for:
- Solo founders building and launching products independently
- Indie hackers focused on rapid iteration and revenue
- Small teams that need to move fast without over-engineering
- Bootstrapped builders who wear multiple hats (dev, ops, marketing)
Goals
Help solo founders:
- Ship faster - Reduce decision fatigue and analysis paralysis
- Build with confidence - Validate technical decisions without a team
- Stay lean - Avoid over-engineering and unnecessary complexity
- Focus on what matters - Prioritize features that drive revenue and traction
Example Use Cases
- Getting a quick audit before launching a new feature
- Generating marketing content from development progress
- Making pragmatic technical decisions without overthinking
- Setting up monitoring and error tracking efficiently
- Validating pricing and go-to-market strategies
- Optimizing cloud costs and infrastructure spend
- Understanding when "good enough" is actually good enough
- Building and optimizing landing pages for conversion
- Getting CRO feedback on copy and page structure
- Setting up lean analytics and conversion tracking
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.
