What it costs to keep this loaded
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 | $0.00078 | $0.01472 |
| Opus 5.5 | $0.00031 | $0.00589 |
| Sonnet 5.5 | $0.00016 | $0.00294 |
| Haiku 4.5 | $0.00008 | $0.00147 |
Grade A, and why
prd-creator 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 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.
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.

PRD Creation Assistant
Transform software ideas into comprehensive PRDs and actionable implementation tasks through a two-part process.
Overview
This skill helps beginner-level developers.
- Receive an implementation description from the user
- Create detailed PRD documents through structured questioning
- Verify implementation prerequisites, including access, MCPs, docs, env variables, and test users
- Generate implementation task lists in JSON format for developers
- Write an overall description of the project. An executive summary that gives a high level overview of the app and its main features.
Part 1: Implementation Description
You will receive a lacking implementation description from the user. The main goal is to comprehend the intent and think about the larger architecture and a robust way to implement it, filling in the gaps.
Part 2: PRD Creation
File: PRD.md
You will need to ask clarifying questions to get a clear understanding of the implementation.
When to use: User wants to document a software idea or create feature specifications
What it does:
- Guides structured questioning to gather all requirements
- Verifies project prerequisites before PRD finalization
- Creates/updates
.env.localwith placeholder values only - Creates executive summary for validation
- Researches competitive landscape
- Generates comprehensive PRD.md with:
- App overview and objectives
- Target audience
- Success metrics and KPIs
- Competitive analysis
- Core features and user flows
- Technical stack recommendations
- Prerequisites and access
- Security considerations
- Assumptions and dependencies
Process:
- Ask clarifying questions using
AskUserQuestiontool - Verify prerequisites and create/update
.env.localplaceholders - Create executive summary for user approval
- Research competition via WebSearch
- Generate complete PRD
- Iterate based on feedback
Read PRD.md for complete instructions.
What ships with it
2 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.

prd-creator is a skill published in the GitHub repository PageAI-Pro/ralph-loop (328 stars, last pushed 1mo ago), licensed MIT. It adds 78 tokens to every session and 1,472 once invoked, about $0.0003 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 2026-08-30.
