idea-griller is a skill for Claude Code from aneja5/forge-skills. It costs 65 tokens per session (1,343 once invoked), scanned A, original, MIT.

A guided questioning process for turning a rough software idea into a clear project brief. It asks one question at a time to uncover unclear assumptions about users, scope, business model, and distribution.

In plain words
What is it for?
Use it to pressure-test a new product, project, or feature before writing a specification.
Why use it?
It exposes gaps and contradictions before they become expensive requirements or code changes.

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-griller 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.

Idea Griller

Overview

Pressure-test a raw idea through Socratic questioning. One question per turn, each built from the user's last answer. Output is .forge/idea-brief.md — a structured brief that lets spec-driven-development skip discovery and go straight to requirements.

When to Use

  • User describes a new idea, project, or feature they haven't fully thought through
  • User wants to stress-test assumptions before writing a spec
  • Idea is vague, contradictory, or needs a sharper scope

When NOT to Use

  • .forge/prd.md already exists — the idea is past this stage
  • User is reporting a bug — use debugging-and-recovery
  • Idea is already well-specified with named users, clear scope, and a distribution plan

Common Rationalizations

Thought Reality
"The idea is obvious, let's skip to the spec" Obvious ideas carry the most unchecked assumptions
"The user knows what they want" They know symptoms — root cause is often different
"One more question is too many" Vague answers compound — drill until specific
"I can infer the business model" Never infer. Ask. You will be wrong.
"The MVP is clear" MVPs defined without drilling risks are over-scoped
"We can resolve distribution later" If you can't name channel + motion now, the idea isn't ready
"We covered the important branches" Important by whose criteria? Distribution and Risks are the most-skipped and the most-costly to miss.

Red Flags

  • User says "everyone" or "all users" — no segment identified
  • Answer to distribution is "word of mouth" or "social media" — not a plan
  • MVP scope grows across turns — riskiest assumption not isolated
  • User can't name a single person who has this problem today
  • Business model is "we'll figure it out later"
  • Founder fit answer is "I'm passionate about this space"
  • Interview stopped before all 7 branches because "the idea is clear enough" or "we ran out of time"

Behavior Rules

  • One question per turn. Always.
  • Generate each question from the user's last answer — never from a fixed script
  • If vague or contradictory: drill deeper on the same branch
  • If clear and specific: acknowledge briefly (one line), advance to next branch
  • Max 3 questions per branch — don't loop forever
  • Push back on weak answers. "People want this" requires evidence.
  • Note unresolved items as open assumptions in the brief

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.
