What it can do on your machine

Read from SKILL.md and the folder at commit 737292f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • uv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • confluence.corp

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Bmad Product Brief loads about 2.9k tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 1,566 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~2.9k

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Create, update, or validate a product brief. Use when the user wants help producing, editing, or validating a brief.

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: uv run {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --key workflow. On 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. Load {project-root}/_bmad/bmm/config.yaml (and config.user.yaml if present). Resolve {user_name}, {communication_language}, {document_output_language}, {planning_artifacts}, {project_name}, {date}.
  6. Greet {user_name} in {communication_language} — and stay in {communication_language} for every turn for the entire run, not just the greeting. Detect intent (create / update / validate). If interactive and intent is unclear, ask; for headless behavior see ## Headless Mode.

Execute each entry in {workflow.activation_steps_append} in order.

Activation is complete. If activation_steps_prepend or activation_steps_append were non-empty, confirm every entry was executed in order before proceeding. Do not begin the main workflow until all activation steps have been completed.

Intent Operating Modes

Create. A brief the user is proud of, that meets their needs, drawn out through real conversation — do not assume: instead converse and understand, and then help craft the best product brief for their needs. Begin in ## Discovery before drafting; the brief comes after the picture is on the table. Shape follows the product and need. Treat {workflow.brief_template} as a starting structure, not a contract: drop sections that do not earn their place, add sections the product needs, reorder freely - create sections for specialized domains or concerns also as needed. The brief serves the product's story, not the template's shape. Bind {doc_workspace} to a fresh folder at {workflow.brief_output_path}/{workflow.run_folder_pattern}/, write brief.md there with YAML frontmatter (title, status, created, updated), and seed the memlog: uv run {project-root}/_bmad/scripts/memlog.py init --workspace {doc_workspace} --field topic="<product>". For Update and Validate, {doc_workspace} is the existing folder of the brief being targeted.

Update. Reconcile an existing brief with a change signal. Before proposing changes, read the brief, addendum, .memlog.md, and original inputs — and run the ## Discovery posture against the change signal (a patch applied without context becomes drift). If .memlog.md is missing (a legacy or pre-standard brief), init it with uv run {project-root}/_bmad/scripts/memlog.py init --workspace {doc_workspace} first — this update is its first entry. Surface conflicts with prior decisions before changing. Headless override: log the reversal via uv run {project-root}/_bmad/scripts/memlog.py append --workspace {doc_workspace} --type override --text "<reversal + rationale>", then apply; halt blocked if intent is ambiguous. If the change is fundamental, offer Create instead of patching.

Validate. Honest critique against the brief's own purpose. Read the brief, the addendum if present, .memlog.md, and any original inputs first — a validation that ignores prior decisions, rejected ideas, or context the user supplied is shallow. Cite specific lines. Caveat what cannot be evaluated. Return inline — no separate file unless asked. Always offer to roll findings into an Update, even in headless mode — include "offer_to_update": true in the JSON status block.

Headless Mode

When invoked headless, do not ask. Complete the intent using what is provided, what exists in {doc_workspace}, or what you can discover yourself. If intent remains ambiguous after inference, halt with a blocked JSON status and a reason field — do not prompt. End with a JSON response listing status, intent, and artifact paths. The intent field must match the detected intent: "create", "update", or "validate". Examples:

json
{
  "status": "complete",
  "intent": "create",
  "brief": "{doc_workspace}/brief.md",
  "addendum": "{doc_workspace}/addendum.md",
  "memlog": "{doc_workspace}/.memlog.md",
  "open_questions": [],
  "external_handoffs": [
    {"directive": "Confluence upload", "tool": "corp:confluence_upload", "url": "https://confluence.corp/PROD/123", "status": "ok"}
  ]
}
json
{
  "status": "complete",
  "intent": "validate",
  "offer_to_update": true
}

Omit keys for artifacts that were not produced.

Discovery

Conversationally surface what the user brings, why this brief exists, the domain, and the form-factor (mobile / web / desktop / multi-surface / hardware / API — what is this thing) — echo back how each shapes your approach. Open with space for the full picture: invite a brain dump and ask up front for any source material they already have (memo, deck, transcript, prior brief, slack thread). Read what exists first; ask only what is missing. After the dump, a simple "anything else?" often surfaces what they almost forgot. Drill into specifics only after the broad shape is on the table; premature granular questions interrupt the dump and miss the room. Get a read on stakes early (passion project, internal pitch, investor input, public launch), and let that calibrate how hard you push. During the dump, spawn web-research subagents to ground the picture — landscape, comparables, current state — AI especially, where training data ages by the week. Subagent searches; parent gets a digest. Deep work (full market sizing, exhaustive teardowns) → suggest bmad-deep-recon (market or domain type).

Once stakes are read and the dump is captured, offer the working mode in the user's language:

  • Fast path — I batch the remaining gaps into one or two consolidated questions, then draft the full brief with [ASSUMPTION] tags where I inferred. You review and we iterate. Best for "I'm pitching tomorrow."
  • Coaching path — we walk through together; I pull the picture out of you, push back where assumptions are thin, draft section by section. Best for "I want a brief I'm proud of and time isn't the constraint."

The workspace persists; stop and resume freely. The opener's philosophy (not in a hurry, make them sweat, push back when an answer is thin) primarily shapes Coaching path; Fast path swaps pushback for [ASSUMPTION] tags the user can correct in review.

Constraints

  • Right-size to purpose. A passion project does not need investor-grade rigor. A VC pitch input does. Read the room.
  • Persistence is real-time. Once Create intent is confirmed, the workspace (run folder, brief.md skeleton with status: draft, .memlog.md seeded via memlog.py init) exists on disk and the user knows the path.
  • File roles. .memlog.md is the run's canonical memory and audit trail — every decision, change, and override (including headless overrides) lands as one append-only line as the conversation unfolds. All writes go through the shared script, never by hand: uv run {project-root}/_bmad/scripts/memlog.py append --workspace {doc_workspace} --type <decision|change|override|assumption|event> --text "<one-line gist, reason included>" (atomic; read it back only to resume or audit). The brief is distilled toward it; whatever isn't logged is lost on resume. addendum.md preserves user-contributed depth that belongs in a downstream document (PRD, architecture, solution design) or earned a place but does not fit the brief (rejected-alternative rationale, options-considered matrices, parked-roadmap context, technical constraints, in-depth personas, sizing data). Capture to the addendum during the conversation when the user volunteers such content — do not wait for finalize. Audit and override information never goes in the addendum.
  • Continuity across sessions. If a prior in-progress draft for this project exists, the user is offered to resume.
  • Extract, don't ingest. Source artifacts (provided by the user or discovered during the run — transcripts, brainstorms, research reports, code, web results, prior briefs) enter the parent conversation as relevance-filtered extracts, not loaded wholesale. Subagents do the extraction against the user's stated focus; the parent context stays lean.
  • Length and coherence. Aim for 1-2 pages — if it is longer, the detail belongs in the addendum. Structure in service of the product; downstream consumers (PRD workflow, etc.) read this, so coherent shape matters.

Finalize

  1. Memlog audit + addendum review: the user ends this step with an explicit, shared accounting of how the meaningful contents of .memlog.md were handled — captured in the brief, captured in addendum.md (which may already hold detail captured during the conversation — see ## Constraints for what belongs there), or set aside as process noise.
  2. Polish: apply each entry in {workflow.doc_standards} (a skill:, file:, or plain-text directive) to brief.md (and addendum.md if it exists). Run passes as parallel subagents - apply all doc standards to brief.md first, then addendum.md so we present a high-quality draft for the user to review and finalize.
  3. External handoffs: execute each entry in {workflow.external_handoffs} to route artifacts beyond local files (Confluence, Notion, ticket systems, etc.) — each directive names the MCP tool and the fields it needs. Invoke the tool, capture any URLs or IDs returned, and surface them in the user message. If a named tool is unavailable, skip that handoff and flag it; local files always exist regardless.
  4. Tell the user it is ready: local paths and external destinations (URLs returned from handoffs). Invoke bmad-help to suggest what next steps make sense in the bmad method ecosystem.
  5. Run {workflow.on_complete} if non-empty. Treat a string scalar as a single instruction and an array as a sequence of instructions executed in order.
