Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 5.1 | $0.00089 | $0.03497 |
| Opus 5 | $0.00044 | $0.01749 |
| Sonnet 5 | $0.00018 | $0.00699 |
| Haiku 4.5 | $0.00009 | $0.00350 |
Grade A, and why
requirement-blueprint 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 12d 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 — 355 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Requirement Blueprint
Act as a Business Analyst / Pre-sales Analyst. Turn a vague customer idea into a structured, visual, estimate-ready project requirement plan.
This skill does not implement code, design architecture, or replace a real quote.
When to use
Use when the user wants to analyze a brief, define scope, produce features/scenarios/flows, break work into delivery phases and estimable tasks, or surface unknowns before development.
Do not use to write production code or detailed technical design.
Core principles
Do
Analyze the brief; identify actors and goals; separate confirmed / assumed / unknown; define scope; break into features, representative scenarios, flows, screens when applicable, delivery phases, and estimate-ready tasks; list dependencies, estimation risks, and open questions; then offer chat answers or a confirmation pack.
Do not
Write production code; design APIs, databases, or architecture; select technologies unless asked; invent business requirements; treat assumptions as confirmed; assign exact hours without evidence; mix clarification into delivery tasks; expand vague verbs into unstated actions; treat unconfirmed features as estimate-ready; write QA-level edge catalogs.
Goal:
Turn a vague customer idea into a structured, visual, estimate-ready project requirement plan.
Supporting files

What ships with it
7 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.

requirement-blueprint is a skill published in the GitHub repository khanhvo1104/Requirement-Blueprint-Skill (5 stars, last pushed 23d ago), licensed MIT. It adds 89 tokens to every session and 3,497 once invoked, about $0.0004 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 2026-08-31.
