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 | $0.00036 | $0.01897 |
| Opus 5.5 | $0.00014 | $0.00759 |
| Sonnet 5.5 | $0.00007 | $0.00379 |
| Haiku 4.5 | $0.00004 | $0.00190 |
Grade A, and why
create-prd 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 22d 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 — 169 lines — stays where its author put it; the contents beside it link to each section on GitHub.
PRD Creation
Follow the phases below to transform product ideas into a complete PRD document. All PRD content is written in Chinese (the target audience is Chinese-speaking teams).
Output Mode
Determine output mode from $ARGUMENTS:
| Argument | Mode | Output |
|---|---|---|
--md (default) |
Local Markdown | Save as .md file to project directory |
--lark |
Feishu Cloud Doc | Create via lark-cli using Lark rich-text features |
--lark mode accepts optional location arguments (mutually exclusive), supporting token or Feishu URL:
--folder-token— Target folder (token or URL)--wiki-node— Target wiki node (token or URL)--wiki-space— Target wiki space root (ID or URL, ormy_library)
Pass URL directly to lark-cli — no manual token extraction needed. Defaults to user's personal space root when no location specified.
Phase 0: Import Context
Check for existing design or requirements documents:
- Search for
docs/,prd/directories or user-specified files - If found, extract key information (problem statement, target users, core features) as pre-filled content
- If nothing found, skip this phase
Phase 1: Determine PRD Type
Ask the user which PRD type they need:
- Full (recommended): All standard sections, suitable for complex features
- Brief: Core sections only, suitable for small features or quick iteration
- One-pager: Single-page summary, suitable for concept validation and executive reporting
Phase 2: Gather Information
Follow the interview questions in references/prd-interview-questions.md, one question at a time. Wait for the answer before continuing.
- Basic info (7 items): required for all types
- Full version extras (5 items): full type only
- AI Agent boundaries: needed when the PRD will be consumed by AI coding agents
If Phase 0 found pre-filled content, show it to the user for confirmation and skip covered questions.
Phase 3: Generate PRD Document
- Select template:
- Full:
references/prd-template-full.md - Brief:
references/prd-template-brief.md - One-pager:
references/prd-template-onepager.md
- Full:
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.

create-prd is a skill published in the GitHub repository FradSer/dotclaude (593 stars, last pushed 7d ago), licensed MIT. It adds 36 tokens to every session and 1,897 once invoked, about $0.0001 per session on Opus 5.5. 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 2026-09-24.
