Token cost

What it costs to keep this loaded

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.

Security

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 5d 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

  1. Frame the bet — restate the idea as: target user, problem, and the painful status quo. Confirm with the user.
  2. Probe demand — who pays, how much, what they use today, why they'd switch. Ask one question at a time.
  3. Assess fit & moat — why this team/stack, what's defensible, what's the riskiest assumption.
  4. Draft the canvas — fill .claude/templates/idea-validation.md into docs/specs/idea-validation.md (draft, await approval). Honor the review intensity: under full, walk through each canvas section for sign-off; under lean, get a single confirmation before writing; under solo, proceed and summarize after.
  5. Director gate — product-director gives a PROCEED / PIVOT / KILL verdict with the single biggest risk to de-risk next.
  6. Next step — on PROCEED, point to /write-prd.

Output

docs/specs/idea-validation.md + a clear verdict. Writes nothing else without approval.

Changes

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.
