A business requirements document authoring guide for defining objectives, stakeholders, scope, target users, and return-on-investment feasibility before product features are designed.

Use it when starting a new product or initiative, or when a change reopens business scope, to define goals and assess whether the work is worthwhile.

It keeps product work tied to business goals instead of starting with an unbounded list of features. It also gives later requirements a traceable source and clear scope boundaries.

Origin original No closer match found in the catalogue.

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	$0.00033	$0.00307
Opus 5.5	$0.00013	$0.00123
Sonnet 5.5	$0.00007	$0.00061
Haiku 4.5	$0.00003	$0.00031

Security

Grade A, and why

sdd-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 19d 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.

What it actually says

SDD BRD Author

Framework skill — routes to framework/layers/01_BRD/BRD-TEMPLATE.yaml and BRD_WORKFLOW_STANDARD.md (entry gate GATE-01). Paths below use <skills-root> = this framework/skills/ directory.

1. When this layer runs

New product or initiative with no prior implementation (SDD2C), or a SEED2C change that re-opens business scope. Never for a DIR2C request — a BRD appearing in a docs/tooling change is a CHG-L019-class scope error.

2. Author from objectives, not features

Build business_objectives, stakeholders, and project_scope first; personas stay high-level target_users here (detailed personas belong to sdd-prd). Run the ROI feasibility evaluation the workflow standard requires — quantitative cost-benefit gates, not narrative justification.

3. Seal the chain of custody

Every downstream layer traces here: PRD features decompose objectives, EARS formalizes them, EVAL verifies them. Leave no objective without an owner and no scope line without a boundary. Gate: GATE-01. Next: sdd-prd.

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.
