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 | $0.00000 | $0.00450 |
| Opus 5.5 | $0.00000 | $0.00180 |
| Sonnet 5.5 | $0.00000 | $0.00090 |
| Haiku 4.5 | $0.00000 | $0.00045 |
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 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.
What it actually says
Create a PRD
Use this skill before any multi-file feature, architectural decision, or complex bug fix.
Activate with: @create-prd
Location and naming
- All PRDs live in
prds/folder - File name:
prds/<feature-or-problem-slug>.md - Extension is always
.md, not.prd - Use kebab-case for the filename (e.g.,
prds/adding-email-auth.md)
Template
Copy and fill in this template:
# [Feature or problem name]
## Summary
1-2 sentence description of what this is and why it matters.
## Problem
What is broken or missing. Include symptoms, error messages, or user-facing impact.
## Root cause (for bugs)
What actually caused it. Do not skip this for bugs.
## Proposed solution
How to fix or build it. Be specific about the approach chosen and why.
## Files to change
- `path/to/file.ts` - what changes and why
- `convex/schema.ts` - if schema changes are needed
## Edge cases and gotchas
Anything non-obvious that came up during analysis. This section saves the next session.
## Verification
How to confirm the fix or feature works:
- [ ] Step 1
- [ ] Step 2
## Related
Links to related PRDs, issues, or external docs if any.
When to create a PRD
- 3+ files will change
- Schema changes are involved
- Architectural decisions are being made (auth, hosting, data model)
- A bug required significant investigation to diagnose
- A feature needs to be referenced later as a migration guide or implementation reference
When to skip a PRD
- Single file bug fix obvious from logs or types
- Typo, CSS tweak, or label change
- Copy change to markdown content
After creating the PRD
- Add the feature tasks to
TASK.mdunder## To Doas checkable items - Reference the PRD path in the TASK.md entry if useful
- Begin implementation only after the plan is clear
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 waynesutton/markdown-site (627 stars, last pushed 5mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 450 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 2026-08-30.
