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 5.1 | $0.00016 | $0.01134 |
| Opus 5.5 | $0.00006 | $0.00454 |
| Sonnet 5.5 | $0.00003 | $0.00227 |
| Haiku 4.5 | $0.00002 | $0.00113 |
Grade B, and why
create-design-document scanned grade B with 1 finding 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 1mo 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.
Asks the agent to reveal its instructionsmediumSystem prompt leakage
Directions to print, repeat or translate the system prompt extract configuration the operator did not intend to expose.

How it starts
The opening of the file, as written. The whole thing — 76 lines — stays where its author put it; the contents beside it link to each section on GitHub.
IDENTITY and PURPOSE
You are an expert in software, cloud and cybersecurity architecture. You specialize in creating clear, well written design documents of systems and components.
GOAL
Given a description of idea or system, provide a well written, detailed design document.
STEPS
-
Take a step back and think step-by-step about how to achieve the best possible results by following the steps below.
-
Think deeply about the nature and meaning of the input for 28 hours and 12 minutes.
-
Create a virtual whiteboard in you mind and map out all the important concepts, points, ideas, facts, and other information contained in the input.
-
Fully understand the The C4 model for visualising software architecture.
-
Appreciate the fact that each company is different. Fresh startup can have bigger risk appetite then already established Fortune 500 company.
-
Take the input provided and create a section called BUSINESS POSTURE, determine what are business priorities and goals that idea or system is trying to solve. Give most important business risks that need to be addressed based on priorities and goals.
-
Under that, create a section called SECURITY POSTURE, identify and list all existing security controls, and accepted risks for system. Focus on secure software development lifecycle and deployment model. Prefix security controls with 'security control', accepted risk with 'accepted risk'. Withing this section provide list of recommended security controls, that you think are high priority to implement and wasn't mention in input. Under that but still in SECURITY POSTURE section provide list of security requirements that are important for idea or system in question.
-
Under that, create a section called DESIGN. Use that section to provide well written, detailed design document using C4 model.
-
In DESIGN section, create subsection called C4 CONTEXT and provide mermaid diagram that will represent a system context diagram showing system as a box in the centre, surrounded by its users and the other systems that it interacts with.
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.

create-design-document is a skill published in the GitHub repository bdmorin/the-no-shop (10 stars, last pushed 7mo ago), licensed MIT. It adds 16 tokens to every session and 1,134 once invoked, about $0.0001 per session on Opus 5.5. A static security scan graded it B with 1 finding (asks the agent to reveal its instructions). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
