A product requirements document (PRD) template and process for turning a feature idea into a clear implementation plan. It covers the feature’s scope, user stories, acceptance criteria, and checks for verifying the result.

Use it to write one complete feature specification, split a larger feature into smaller deliverables, and define testable requirements for each part.

It keeps important decisions and details from being lost between planning and coding. Smaller PRDs also make large features easier to build and check in parts.

Token cost

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	$0.00026	$0.01649
Opus 5	$0.00013	$0.00825
Sonnet 5	$0.00005	$0.00330
Haiku 4.5	$0.00003	$0.00165

Security

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 4d 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 — 140 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Create PRD

Quick Start

Copy the template: assets/prd-template.md
Fill it out in the target dossier:
- Single-PRD dossier: prd.md
- Multi-PRD dossier:
  - Overall / spine PRD at the dossier root: prd-overall.md
  - Slice PRDs under prds/: prds/<slice_id>_<slug>/prd.md
Notes:
- Lowest-level PRD filenames are always prd.md (no prd-slice-* filenames).
- Use a short kebab-case slug like auth-token-rotation or invoice-pdf-export.
Pull all details from shaping inputs into the PRD so it’s implementable without extra context (no information loss)

PRD Slicing Rubric (Reusable)

Rules of thumb (thin PRDs)

One PRD should deliver one user-visible affordance (or one backend capability with a measurable, observable effect), not a whole workflow.
Each PRD must have measurable acceptance criteria tied to at least one replayable verification pack (fixture data, synthetic dataset, scripted scenario, etc.).
Keep PRDs vertical-ish: UI + a thin API/data change where needed, but avoid building platform layers unless they directly unblock the next slice.
If a PRD introduces a new failure mode, it must also introduce the UX to surface it (no silent failures).
Prefer scaffold then replace: ship a deterministic baseline behind stable contracts first, then swap in ML/OCR/retrieval/LLM (or other complex components) behind the same interface.

Examples (good slices)

"UI affordance X triggers state Y, persists, and is visible after refresh."
"API returns payload + stable checksum/hash so clients can detect mismatches."
"Verifier rejects records on checksum mismatch and surfaces a user-visible error state."
"Parser extracts a single structured list into a table with row-level provenance."

Examples (bad slices)

"Build ingestion + parsing + retrieval + drafting + verification + export" (too many risks bundled).
"Implement an autonomous multi-agent copilot" (non-deterministic + typically too broad for a single slice).
"Add full template/customisation system" (platform work without proving the core loop).

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 marchatton/agent-skills (5 stars, last pushed 5mo ago), licensed MIT. It adds 26 tokens to every session and 1,649 once invoked, about $0.0001 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 2026-08-31.
