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 | $0.00031 | $0.00632 |
| Opus 5 | $0.00015 | $0.00316 |
| Sonnet 5 | $0.00006 | $0.00126 |
| Haiku 4.5 | $0.00003 | $0.00063 |
Grade A, and why
rapid-saas-builder 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 11d 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.

The opening of the file, as written. The whole thing — 103 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Rapid SaaS Builder
Use this skill after PRD.md exists and the MVP scope is approved. Rapid SaaS Builder turns product requirements into a staged AI-assisted SaaS build workflow.
This skill is for execution, not validation. It should not validate business ideas, create marketing plans, expand product strategy, or invent features outside the PRD.
Primary Purpose
Create a clear, checklist-based build pipeline for:
- Planning / PRD
- Frontend Development
- Backend Development
- Integration
- Deploy
- Testing
Required Inputs
Use as many of these as available:
PRD.mdTASKS.mdUSER_FLOW.mdMVP_CHECKLIST.mdARCHITECTURE_REVIEW.md- Tech stack or repository context
- Deployment target
- Authentication, database, payment, and integration requirements
If PRD.md is missing, stop and ask for it. If architecture is missing, proceed with conservative assumptions and flag them.
Default Output Format
- Build Summary
- Required Inputs
- Frontend Plan
- Backend Plan
- Integration Plan
- Deployment Plan
- Testing Plan
- Tool Recommendations
- MVP Guardrails
- Next Implementation Tasks
Operating Rules
- Build only the MVP scope from
PRD.md. - Do not validate the business idea.
- Do not create marketing plans.
- Do not add features because they are "standard SaaS" unless the PRD requires them.
- Avoid overengineering.
- Prefer simple, proven tools.
- Prefer one deployable product over fragmented services.
- Keep stages small and independently verifiable.
- Use checklists for each stage.
- Treat AI coding tools as accelerators, not decision-makers.
- For mobile apps, do not implement external checkout for in-app digital goods, credits, premium features, or subscriptions unless a documented store-policy exception applies. Use Apple IAP / Google Play Billing, often via RevenueCat.
MVP Guardrails
Always include:
- In scope.
- Out of scope.
- Assumptions.
- Dependencies.
- Manual steps allowed.
- What not to build yet.
- Verification required before moving to the next stage.
What ships with it
6 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.

rapid-saas-builder is a skill published in the GitHub repository wolulabs/hermes-founder-os (18 stars, last pushed 3mo ago), licensed MIT. It adds 31 tokens to every session and 632 once invoked, about $0.0002 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.
