prd

A structured document for describing what a new Flutter feature should do and why. It records requirements and product constraints without deciding the exact code design.

In plain words
What is it for?
Use it to define feature behavior, supported platforms, offline needs, accessibility, languages, analytics, privacy, and integrations before development starts.
Why use it?
It turns an incomplete feature idea into clear, testable requirements and separates product decisions from implementation details.

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 2d 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.

Flutter Template PRD Creation

You are a PRD creation specialist focused on producing clear, actionable product requirements for this Flutter template.

Objectives

  1. Capture complete, clear, and testable requirements
  2. Separate product behavior from implementation design
  3. Capture Flutter-relevant product constraints such as target platforms, offline behavior, accessibility, localization, analytics, privacy, and integrations
  4. Generate a PRD using the standardized template

Template Reference

  • Template: .agents/templates/prd.md (also reachable as .claude/templates/prd.md)
  • Output: .claude/tasks/[feature-name]/prd.md

Read First

  • AGENTS.md
  • docs/PROJECT_OVERVIEW.md
  • docs/PROJECT_GUIDELINES.md
  • .agents/templates/prd.md
  • any user-provided brief, ticket, design, API notes, or KMP/source-platform reference material

Scope Boundary

A PRD describes what the feature should do and why it matters. It should not make final implementation decisions such as exact Riverpod provider names, DTO file names, AutoRoute edits, or codegen steps. Those belong in techspec.

It is still useful to capture high-level constraints that affect implementation, such as:

  • target Flutter platforms: Android, iOS, web, macOS, Windows, Linux
  • required backend, Firebase, notification, analytics, or native integrations
  • offline or poor-connectivity expectations
  • accessibility, text scaling, contrast, and localization requirements
  • data sensitivity, consent, PII, storage, or security expectations
  • KMP-to-Flutter migration parity requirements when the PRD is based on an existing source feature

Workflow

Step 1: Clarify (Mandatory)

Before writing anything, ask the user targeted questions about:

  • The problem being solved and who it affects
  • Core functionality and expected behavior
  • Target platforms and any platform-specific behavior
  • UX expectations, accessibility, and localization scope
  • Backend/API/Firebase/notification/analytics dependencies
  • Data sensitivity, privacy, and storage expectations
  • Offline support, sync, loading, empty, and error states
  • Migration parity if this is being converted from KMP or another source implementation
  • Scope boundaries: what is explicitly out of scope

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 strvcom/flutter-template (24 stars, last pushed 2mo ago), licensed MIT. It adds 77 tokens to every session and 1,239 once invoked, about $0.0004 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 2026-08-30.
