skill

skill is a skill for Claude Code, Codex from matteocervelli/llms. It costs 16 tokens per session (660 once invoked), scanned A, original, MIT.

A skill for collecting product-assessment answers one at a time and storing them in structured JSON. It covers questions about the problem, users, business case, outcome, risks, and go/no-go decisions.

In plain words
What is it for?
Use it for product-idea evaluations, go/no-go reviews, team input, and maintaining an audit trail of product decisions.
Why use it?
It keeps earlier answers intact while making an assessment easier to complete and review systematically.

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

skill 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 4d 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.

Answer Collector Skill

Purpose: Incrementally collect and validate product assessment responses in structured JSON format.


When to Use

  • Evaluating new product ideas with rigorous criteria
  • Conducting go/no-go assessments before committing resources
  • Building a decision audit trail for product decisions
  • Gathering structured input from teams or stakeholders
  • Progressive refinement of product hypotheses

How It Works

1. Reading Questions

Questions are organized in 4 sections (questions.md):

  • WHY (4 Q's): Problem, strategy, resources, timing
  • WHO (4 Q's): User, access, economics, scale
  • WHAT (5 Q's): Outcome, monetization, success metrics, fit, risk
  • GO/NO-GO (4 criteria): Checklist for final decision

Each question is numbered 1-17.

2. Writing JSON Incrementally

Start with a template and add answers one at a time:

{
  "metadata": {
    "product_name": "Your Product Name",
    "created_at": "2025-11-03T00:00:00Z",
    "status": "in_progress"
  },
  "answers": {
    "why_section": {
      "q1_problem_evidence": "Answer here..."
    }
  }
}

Build incrementally:

  • Add one answer per interaction
  • Preserve all previous answers
  • Update last_updated timestamp
  • Track completion_percentage in metadata

3. Validation Logic

Auto-calculate:

  • answered_questions: Count non-empty answers
  • completion_percentage: (answered_questions / 17) × 100
  • go_no_go_result: "go" if all 4 checklist items true, else "no_go" or "pending"

Validation rules:

  • All text answers must be non-empty and substantive
  • Checklist items (q14-q17) must be boolean (true/false)
  • Metadata fields (product_name) required to start
  • All timestamps in ISO 8601 format

Quick Reference

Section Questions Type
WHY 1-4 Text
WHO 5-8 Text
WHAT 9-13 Text
GO/NO-GO 14-17 Boolean

Usage Pattern

  1. Initialize: Create JSON with metadata and product_name
  2. Collect: Answer one question, validate, save
  3. Review: Check completion_percentage and go_no_go_result
  4. Decide: When all answers complete, review go_no_go_result

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.

skill is a skill published in the GitHub repository matteocervelli/llms (25 stars, last pushed 3mo ago), licensed MIT. It adds 16 tokens to every session and 660 once invoked, about $0.0001 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 2026-09-01.
