brd

A workflow for generating a Business Requirements Document (BRD), a document describing the business needs and scope of a software product, from a business plan. It requires specific planning files and produces the full stated product scope.

In plain words
What is it for?
Use it to generate a BRD from a business plan after the required business-plan and technology-stack files are present.
Why use it?
It turns an existing business plan into a structured requirements document and avoids leaving described features out because of informal phasing.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

brd 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.

How it starts

The opening of the file, as written. The whole thing — 205 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Transmute — BRD Generation (Stage 1)

Read the detailed guide at ${CLAUDE_SKILL_ROOT}/references/brd-detailed-guide.md for the complete agent team architecture, teammate spawn prompts, token budget management, review agent checklists, remediation procedures, and writing guidelines.

Prerequisites

Before starting, verify:

  1. ./plancasting/businessplan/ directory exists and contains .md or .pdf files. If missing or empty, STOP: "Stage 1 requires a Business Plan at ./plancasting/businessplan/. Place your business plan files (.md or .pdf) there before running Stage 1."
  2. ./plancasting/tech-stack.md exists (created by Stage 0). If missing, STOP: "Stage 1 requires plancasting/tech-stack.md from Stage 0. Run Stage 0 first."

Critical Framing

This BRD uses the Full-Build Approach: ALL features described in the Business Plan are built as a single, complete product. No MVP, no phased rollout, no feature deferral. If the Business Plan describes "Phase 1, Phase 2, Phase 3" — IGNORE the phasing. Features labeled "future", "planned", "roadmap", or "long-term" are INCLUDED in full scope. Only features explicitly marked "out-of-scope" are excluded.

Execution Flow

Step 1: Read and Analyze Inputs

Read and fully internalize:

  • All files in ./plancasting/businessplan/ (supported formats: .md and .pdf)
  • ./plancasting/tech-stack.md

Check Session Language in ./plancasting/tech-stack.md. Generate ALL BRD documents in the specified language. Technical identifiers (requirement IDs like FR-001, section headers, cross-reference codes) remain in English.

Language Inheritance: Subsequent stages (PRD, audits, reports) will read the Session Language section from plancasting/tech-stack.md — NOT from BRD documents. The BRD's language serves as a reference, but the canonical language setting is always in tech-stack.md.

Adapt BRD structure based on product type in plancasting/tech-stack.md:

  • Web applications: Standard structure
  • Mobile applications: Add platform-specific requirement categories (App Store/Play Store guidelines, device permissions, offline capabilities)
  • IoT / Embedded: Add hardware requirement categories (environmental requirements, power requirements, connectivity protocols, certification requirements)
  • Desktop applications: Add platform-specific requirements (Windows/macOS/Linux compatibility, installation/update mechanisms, system resource requirements)
  • AI/ML products: Add model requirement categories (training data requirements, inference latency, accuracy metrics, bias/fairness requirements)

Files

What ships with it

1 file 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.

brd is a skill published in the GitHub repository VoxTechnologies/transmute-framework (4 stars, last pushed 1mo ago), licensed MIT. It adds 79 tokens to every session and 3,457 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 2026-08-31.
