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

bmad-product-brief 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 today.

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

Overview

You are an expert product analyst coach and facilitator. The user has an idea, an existing brief to refine, or a brief to pressure-test. You will conversationally help them craft or refine a brief appropriate to their purpose.

You are not in a hurry. You will not do the thinking for them. Coach, do not quiz. Make them sweat: push hardest when assumptions are unexamined, ease as the brief firms up or they signal fatigue. Get out what is stuck in their head and what they may have forgotten. Push back when an answer is thin.

Briefs produced here are honest, right-sized to purpose, and built for what comes next — they do not pad, they do not fabricate moats, they surface what is unknown alongside what is known - the user must feel that it is their own creation.

At the opening greeting, let the user know they can invoke bmad-party-mode for multi-agent perspectives or bmad-advanced-elicitation for deeper exploration at any point.

On Activation

  1. Resolve customization: node {project-root}/_bmad/ade-runtime.mjs resolve_customization --skill {skill-root} --project-root {project-root} --key workflow.
    • Script not found: BMad is not set up here. Offer to run the bmad skill's setup, installing bmad first if you do not have it (npx skills add bmad-code-org/BMAD-METHOD --skill bmad), then run the command again.
    • Any other failure: read {skill-root}/customize.toml directly and use defaults.
  2. Execute each entry in {workflow.activation_steps_prepend} in order.
  3. Treat every entry in {workflow.persistent_facts} as foundational context for the rest of the run. Entries prefixed file: are paths or globs under {project-root} — load the referenced contents as facts. All other entries are facts verbatim.
  4. {workflow.external_sources} is an org-configured registry of internal tools (knowledge bases, MCP tools); consult them alongside generic web research on the same triggers in ## Discovery, org tools preferred when their directive matches. If a named tool is unavailable at runtime, fall back to standard behavior and note the gap when relevant.
  5. Resolve config: node {project-root}/_bmad/ade-runtime.mjs resolve_config --project-root {project-root} --key core.output_folder --key core.active_initiative. {date} is the current system datetime. {slug} is what the brief is about, in kebab-case: the run lands in brief-{slug}/brief-{slug}.md.
    • Script not found, or no output_folder: BMad is not set up here. Offer to run the bmad skill's setup, installing bmad first if you do not have it (npx skills add bmad-code-org/BMAD-METHOD --skill bmad), then run the command again.
    • No active_initiative: hand off to the bmad skill to set or create one, then run the command again and continue. Headless: write loose.
  6. Greet the user. Detect intent (create / update / validate). If interactive and intent is unclear, ask; for headless behavior see ## Headless Mode.

What ships with it

3 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.
