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 | $0.00076 | $0.03333 |
| Opus 5 | $0.00038 | $0.01666 |
| Sonnet 5 | $0.00015 | $0.00667 |
| Haiku 4.5 | $0.00008 | $0.00333 |
Grade A, and why
pdd 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 11d 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 — 295 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Prompt-Driven Development
Overview
This sop guides you through the process of transforming a rough idea into a detailed design document with an implementation plan and todo list. It follows the Prompt-Driven Development methodology to systematically refine your idea, conduct necessary research, create a comprehensive design, and develop an actionable implementation plan. The process is designed to be iterative, allowing movement between requirements clarification and research as needed.
Parameters
- rough_idea (required): The initial concept or idea you want to develop into a detailed design
- project_dir (optional, default: ".sop/planning"): The base directory where all project files will be stored
Constraints for parameter acquisition:
- You MUST ask for all required parameters upfront in a single prompt rather than one at a time
- You MUST support multiple input methods including:
- Direct input: Text provided directly in the conversation
- File path: Path to a local file containing the rough idea
- URL: Link to an internal resource (e.g., Quip doc, wiki page)
- Other methods: You SHOULD be open to other ways the user might want to provide the idea
- You MUST use appropriate tools to access content based on the input method
- You MUST confirm successful acquisition of all parameters before proceeding
- You SHOULD save the acquired rough idea to a consistent location for use in subsequent steps
- You MUST NOT overwrite the existing project directory because this could destroy previous work and cause data loss
- You MUST ask for project_dir if it is not given and default ".sop/planning" directory already exist and has contents from previous iteration
Steps
1. Create Project Structure
Set up a directory structure to organize all artifacts created during the process.
Constraints:
- You MUST create the specified project directory if it doesn't already exist
- You MUST create the following files:
- {project_dir}/rough-idea.md (containing the provided rough idea)
- {project_dir}/idea-honing.md (for requirements clarification)
- You MUST create the following subdirectories:
- {project_dir}/research/ (directory for research notes)
- {project_dir}/design/ (directory for design documents)
- {project_dir}/implementation/ (directory for implementation plans)
- You MUST notify the user when the structure has been created
- You MUST prompt the user to add all project files to Q's context using the command:
/context add {project_dir}/**/*.md - You MUST explain that this will ensure all project files remain in context throughout the process
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.

pdd is a skill published in the GitHub repository brazil-bench/pourpoise (11 stars, last pushed 8mo ago), licensed Apache-2.0. It adds 76 tokens to every session and 3,333 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 2026-08-30.
