idea-gate

idea-gate is a command for Claude Code from heyparsadev/claude-idea-validator. It costs 15 tokens per session (301 once invoked), scanned A, original, MIT.

A command that evaluates whether an early business idea has enough evidence to justify building it.

In plain words
What is it for?
Use it to score the idea stage, record a PROCEED, ITERATE, PIVOT, KILL, or BLOCKED decision, and update the venture records.
Why use it?
It replaces an informal go-or-no-go decision with a review of supporting and challenging evidence, bias checks, and predefined stop conditions.

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

idea-gate 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.

What it actually says

Score the Idea-stage exit gate for: $ARGUMENTS

Invoke founder-playbook:idea-stage and run step 10 only. Read references/evidence-ledger.md for the gate arithmetic.

  1. Read ventures/<slug>/00-idea-stage/EVIDENCE.md and tally the grade balance (supporting vs challenging, by grade).
  2. Run the six-question bias audit before scoring. Write the answers down.
  3. Score the three exit questions, each with its best available evidence grade attached:
    • Is the problem real and specific? — requires grade A
    • Does the solution address the actual problem discovery revealed? — requires A or B
    • Is there enough signal to justify building?
  4. Check the step-0 kill criteria. A criterion met outweighs a favorable-looking scorecard — that's what writing them in advance was for.
  5. Write the verdict to DECISION.md, append to VENTURE.md's decision log, and state it to the founder plainly and unsoftened.

Verdicts: PROCEED · ITERATE · PIVOT · KILL · BLOCKED (no interviews yet — the only honest verdict when the ledger has no grade-A rows).

Respond in the founder's language.

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.
