prd

prd is a skill for Claude Code, Codex from jstoup111/ai-conductor. It costs 43 tokens per session (1,446 once invoked), scanned A, original, Apache-2.0.

A product-requirements document writer for features that affect product behavior. It records the goals and testable requirements that later become user stories, without prescribing the internal implementation.

In plain words
What is it for?
Use it in the product track after exploration has confirmed that a requirements document is needed.
Why use it?
It gives product work a clear, verifiable definition before planning and coding begin.

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.

Security

Grade A, and why

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 13d 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 — 124 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Purpose

Author the product requirements document for a product-track feature: the what and why, enumerated as testable functional requirements that stories extract from directly. Runs only when /explore set Track: product; technical-track features skip this step entirely.

Correctness gate: functional requirements are load-bearing — stories extract from them directly. Apply the /verify-claims protocol before locking FRs: any FR resting on an assumption about user need, scope, or existing behavior must be flagged with its confidence and HARD-BLOCKED for operator approval (or HALTed if autonomous) — never lock an FR on an unconfirmed assumption.

Boundaries

prd produces a single artifact — a design doc in .docs/specs/ — and nothing else.

Do NOT:

  • Write code, migrations, configs, tests, stubs, plans, or stories
  • Create files outside .docs/specs/
  • Invoke /plan, /stories, or any other skill

Product-only — the hard rule

A PRD states goals and requirements. It MUST NOT name the new internal mechanism by which this feature is built. These are leaks no matter how convenient:

  • command names, subcommands, or CLI flags
  • file paths, directory layouts, config-file names, or config keys
  • function / class / module / type names, signatures, or pseudocode
  • the library / protocol / service / mechanism chosen for this feature (e.g. "via an MCP server", "a symlink", "SQLite", "a post-checkout hook", a named algorithm)
  • data schemas, table/column names, wire formats, ports

Name the capability or behavior ("the operator can adopt a platform in one action"), never the mechanism. Carve-out: a pre-existing external constraint or dependency the feature must live within (an existing API it must call, "must run offline", a mandated datastore) MAY be named as a requirement under Dependencies or Non-Functional Requirements — that is product reality, not a leaked internal mechanism. The distinction: choosing a new internal mechanism = leak; stating an external constraint we don't control = requirement.

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.

Changes

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 is a skill published in the GitHub repository jstoup111/ai-conductor (7 stars, last pushed today), licensed Apache-2.0. It adds 43 tokens to every session and 1,446 once invoked, about $0.0002 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 2026-08-31.
