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.

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 | $0.00000 | $0.00393 |
| Opus 5 | $0.00000 | $0.00197 |
| Sonnet 5 | $0.00000 | $0.00079 |
| Haiku 4.5 | $0.00000 | $0.00039 |
Grade A, and why
plan 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 5d 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.
What it actually says
Architecture & Planning Skill
Skill, System Design, Architecture, Planning
Context
Use this prompt when you are at the beginning of a project or feature and need to design the architecture, define the data models, map out the API contracts, or break down the implementation steps. This skill forces the AI to think like a Principal Architect.
Variables
{{project_goal}}: High-level description of what you are trying to build.{{tech_stack}}: The languages, frameworks, and databases you are using.{{constraints}}: Any technical, business, or timeline constraints.
Prompt
Adopt the persona of a Principal Software Architect. I need your expertise to design the architecture and implementation plan for the following project:
Goal: {{project_goal}}
Tech Stack: {{tech_stack}}
Constraints: {{constraints}}
Please provide a comprehensive architectural design that includes:
1. **System Overview:** A high-level explanation of how the system will work.
2. **Component Breakdown:** The major modules, services, or components required.
3. **Data Flow & Models:** How data moves through the system and the core schema structures.
4. **Risk Mitigation:** Potential bottlenecks, security concerns, or technical debt, and how to avoid them.
5. **Implementation Steps:** A logical, ordered sequence of development tasks to build this.
Do not write the implementation code. Focus purely on the design and architecture.
Example Usage
Input:
Adopt the persona of a Principal Software Architect. I need your expertise to design the architecture and implementation plan for the following project:
Goal: Build a real-time collaborative markdown editor.
Tech Stack: Next.js, WebSockets, Redis, PostgreSQL
Constraints: Must handle up to 50 concurrent users on the same document without latency issues.
Please provide a comprehensive architectural design that includes:

What ships with it
8 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.

plan is a skill published in the GitHub repository DongDuong2001/pudo-code-system (5 stars, last pushed 29d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 393 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.

scale-to-millions
Use this skill whenever the user is designing, reviewing, debugging, or answering interview questions about system/software architecture and scalability — e.g. "scale my app", "how do I handle more traffic", "design a URL shortener / news feed / chat system", "my API is slow under load", "should I shard my database"…

verify-before-claim
Use when an agent is about to claim completion, correctness, safety, publication, deployment, or any consequential external fact.
