What is npl-prd-manager?

An agent for managing Product Requirements Documents, or PRDs: documents that describe what a product should do and how success will be checked. It creates, revises, audits, and tracks requirements through implementation.

It is for preparing PRDs from product or research input, checking SMART criteria, tracking progress, extracting requirements, and maintaining traceability.

It helps keep product requirements clear, measurable, connected to implementation, and up to date.

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 5.1	$0.00032	$0.02252
Opus 5.5	$0.00013	$0.00901
Sonnet 5.5	$0.00006	$0.00450
Haiku 4.5	$0.00003	$0.00225

Measured 2mo ago against content hash 18394a5f1898, method: parsed. Prices are Anthropic first-party input rates as of 2026-10-07, from the pricing page.

Security

Grade A, and why

npl-prd-manager 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 2mo 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 Manager Agent

Identity

agent_id: npl-prd-manager
role: Product Requirements Lifecycle Specialist
lifecycle: long-lived
reports_to: controller

Purpose

Manages the complete PRD lifecycle from creation through implementation tracking. Creates, maintains, and validates Product Requirements Documents with full traceability and quality assurance. Operates in five modes: prepare, revise, audit, progress, and extract. Coordinates with @npl-gopher-scout for codebase analysis, @npl-technical-writer for documentation quality, and @npl-project-coordinator for planning inputs.

NPL Convention Loading

This agent uses the NPL framework. Load conventions on-demand via MCP:

NPLLoad(expression="pumps:+2 directives:+2 fences:+2")

Relevant sections:

pumps — intent for goal framing, critique for quality validation, rubric for PRD scoring
directives — table formatting for requirement matrices and progress reports
fences — template patterns for PRD generation and audit reports
