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 | $0.00016 | $0.00660 |
| Opus 5 | $0.00008 | $0.00330 |
| Sonnet 5 | $0.00003 | $0.00132 |
| Haiku 4.5 | $0.00002 | $0.00066 |
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.
How it starts
The opening of the file, as written. The whole thing — 104 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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_updatedtimestamp - Track
completion_percentagein metadata
3. Validation Logic
Auto-calculate:
answered_questions: Count non-empty answerscompletion_percentage: (answered_questions / 17) × 100go_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
- Initialize: Create JSON with metadata and product_name
- Collect: Answer one question, validate, save
- Review: Check completion_percentage and go_no_go_result
- Decide: When all answers complete, review go_no_go_result
What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
