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 | $0.00050 | $0.00378 |
| Opus 5.5 | $0.00020 | $0.00151 |
| Sonnet 5.5 | $0.00010 | $0.00076 |
| Haiku 4.5 | $0.00005 | $0.00038 |
Grade A, and why
validate-idea 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 1mo 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.
What it actually says
Validate that a SaaS idea is worth building before investing in specs and code. Non-autonomous: ask first, present options, get sign-off.
Phases
- Frame the bet — restate the idea as: target user, problem, and the painful status quo. Confirm with the user.
- Probe demand — who pays, how much, what they use today, why they'd switch. Ask one question at a time.
- Assess fit & moat — why this team/stack, what's defensible, what's the riskiest assumption.
- Draft the canvas — fill
.claude/templates/idea-validation.mdintodocs/specs/idea-validation.md(draft, await approval). Honor the review intensity: underfull, walk through each canvas section for sign-off; underlean, get a single confirmation before writing; undersolo, proceed and summarize after. - Director gate — product-director gives a PROCEED / PIVOT / KILL verdict with the single biggest risk to de-risk next.
- Next step — on PROCEED, point to
/write-prd.
Output
docs/specs/idea-validation.md + a clear verdict. Writes nothing else without approval.
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.

validate-idea is a skill published in the GitHub repository evgenii-studitskikh/Claude-Code-SaaS-Studio (2 stars, last pushed 4mo ago), licensed MIT. It adds 50 tokens to every session and 378 once invoked, about $0.0002 per session on Opus 5.5. 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 2026-08-31.
