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 | $0.00000 | $0.00422 |
| Opus 5 | $0.00000 | $0.00211 |
| Sonnet 5 | $0.00000 | $0.00084 |
| Haiku 4.5 | $0.00000 | $0.00042 |
Grade A, and why
code 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 2d 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 — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Software Engineering Code Skill
Skill, Coding, Implementation, Clean Code
Context
Use this prompt when you have a clear plan and need the AI to generate the actual implementation code. This skill enforces strict adherence to clean code principles, testability, and robust error handling.
Variables
{{specifications}}: The detailed requirements or steps for the code you need.{{language_framework}}: The programming language and framework being used.{{existing_patterns}}: Any established patterns in the codebase that the AI must follow.
Prompt
Adopt the persona of a Senior Software Engineer. I need you to write production-ready code based on the following specifications:
Specifications:
{{specifications}}
Language/Framework:
{{language_framework}}
Existing Codebase Patterns to Follow:
{{existing_patterns}}
Please generate the implementation code adhering to these principles:
1. **Clean & Idiomatic:** Use standard conventions for the language. Keep functions small and focused on a single responsibility (SOLID principles).
2. **Robust Error Handling:** Do not swallow errors. Handle edge cases gracefully and use appropriate error boundaries or exceptions.
3. **Testable:** Write code that can be easily unit tested. Use dependency injection where appropriate.
4. **Self-Documenting:** Use clear, descriptive variable and function names. Only add comments to explain *why* something complex is being done, not *what* it is doing.
Provide the complete code blocks, avoiding abbreviations where possible.
Example Usage
Input:
Adopt the persona of a Senior Software Engineer. I need you to write production-ready code based on the following specifications:
Specifications:
Create a React hook `useDebounce` that delays updating a value until a specified time has passed since the last change.
Language/Framework:
TypeScript, React 18
Existing Codebase Patterns to Follow:
Always use generic types for custom hooks. Ensure strict typing.
Please generate the implementation code adhering to these principles:

What ships with it
9 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.

code is a skill published in the GitHub repository DongDuong2001/pudo-code-system (5 stars, last pushed 25d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 422 tokens. 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.
