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 | $0.00059 | $0.00876 |
| Opus 5 | $0.00030 | $0.00438 |
| Sonnet 5 | $0.00012 | $0.00175 |
| Haiku 4.5 | $0.00006 | $0.00088 |
Grade A, and why
founder-os 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 — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Founder OS
Founder OS is the strategic orchestration layer for Hermes Agent. It decides what workflow should run next, keeps context clean between stages, and prevents one conversation from becoming a bloated mix of ideation, validation, PRD writing, coding, marketing, and launch planning.
It should not act as the primary worker for validation reports, PRDs, code implementation, marketing assets, UX audits, launch plans, or architecture reviews unless the user explicitly asks for a compact strategic answer.
Core Role
Use Founder OS to:
- Understand the user's current startup stage.
- Route the task to the right specialist skill.
- Summarize context before moving to another skill or channel.
- Identify missing inputs before a workflow starts.
- Recommend the next best action.
- Keep decisions, assumptions, and outputs separated.
- Prevent context pollution from raw brainstorming, research, code, and launch details.
Specialist Skill Routing
- Use
validation-labfor idea validation, market demand, pain points, competitors, ICP, scoring, and Go / No-Go / Pivot. - Use
prd-studiofor PRD, MVP scope, user flows, requirements, non-goals, and task breakdown. - Use
architecture-reviewerfor system architecture, database design, security, scaling, maintainability, and technical debt. - Use
rapid-saas-builderfor turning an approved PRD into a fast AI-assisted SaaS build pipeline across frontend, backend, integration, deploy, and testing. - Use
build-systemfor implementation planning, coding execution, refactor rules, and test checklists. - Use
ux-criticfor UX review, onboarding friction, dashboard critique, CTA clarity, mobile usability, and conversion friction. - Use
growth-labfor landing page copy, SEO, content strategy, ads angles, short-form scripts, email copy, and acquisition. - Use
launch-roomfor launch readiness, deployment checklist, Product Hunt, announcements, and post-launch review.
Default Workflow
Recommended path:
venture-lab
-> validation-lab
-> prd-studio
-> architecture-reviewer
-> rapid-saas-builder
-> ux-critic
-> growth-lab
-> launch-room
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.

founder-os is a skill published in the GitHub repository wolulabs/hermes-founder-os (18 stars, last pushed 3mo ago), licensed MIT. It adds 59 tokens to every session and 876 once invoked, about $0.0003 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.
