What it does

Bmad Product Brief is an agent skill from delorenj/mcp-server-trello. Create or update product briefs through guided or autonomous discovery. Use when the user requests to create or update a Product Brief.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 14 other files (for example `agents/artifact-analyzer.md`, `agents/opportunity-reviewer.md` and `agents/skeptic-reviewer.md`).

The repository describes itself as: A Model Context Protocol (MCP) server that provides tools for interacting with Trello boards. The licence is MIT.

When your agent uses it

  • The user requests to create
  • Update a Product Brief

Example prompts

  • “/bmad-product-brief”

Requirements

  • Python 3

Workflow steps

6 steps, taken from the step headings in SKILL.md.

  1. Resolve the Workflow Block
  2. Execute Prepend Steps
  3. Load Persistent Facts
  4. Load Config
  5. Greet the User
  6. Execute Append Steps

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:

    • python3

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

  • Network

    No URLs in SKILL.md.

    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 1.8k tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 909 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k

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.

Create Product Brief

Overview

This skill helps you create compelling product briefs through collaborative discovery, intelligent artifact analysis, and web research. Act as a product-focused Business Analyst and peer collaborator, guiding users from raw ideas to polished executive summaries. Your output is a 1-2 page executive product brief — and optionally, a token-efficient LLM distillate capturing all the detail for downstream PRD creation.

The user is the domain expert. You bring structured thinking, facilitation, market awareness, and the ability to synthesize large volumes of input into clear, persuasive narrative. Work together as equals.

Design rationale: We always understand intent before scanning artifacts — without knowing what the brief is about, scanning documents is noise, not signal. We capture everything the user shares (even out-of-scope details like requirements or platform preferences) for the distillate, rather than interrupting their creative flow.

Conventions

  • Bare paths (e.g. prompts/finalize.md) resolve from the skill root.
  • {skill-root} resolves to this skill's installed directory (where customize.toml lives).
  • {project-root}-prefixed paths resolve from the project working directory.
  • {skill-name} resolves to the skill directory's basename.

Activation Mode Detection

Check activation context immediately:

  1. Autonomous mode: If the user passes --autonomous/-A flags, or provides structured inputs clearly intended for headless execution:

    • Ingest all provided inputs, fan out subagents, produce complete brief without interaction
    • Route directly to prompts/contextual-discovery.md with {mode}=autonomous
  2. Yolo mode: If the user passes --yolo or says "just draft it" / "draft the whole thing":

    • Ingest everything, draft complete brief upfront, then walk user through refinement
    • Route to Stage 1 below with {mode}=yolo
  3. Guided mode (default): Conversational discovery with soft gates

    • Route to Stage 1 below with {mode}=guided

On Activation

Step 1: Resolve the Workflow Block

Run: python3 {project-root}/_bmad/scripts/resolve_customization.py --skill {skill-root} --key workflow

If the script fails, resolve the workflow block yourself by reading these three files in base → team → user order and applying the same structural merge rules as the resolver:

  1. {skill-root}/customize.toml — defaults
  2. {project-root}/_bmad/custom/{skill-name}.toml — team overrides
  3. {project-root}/_bmad/custom/{skill-name}.user.toml — personal overrides

Any missing file is skipped. Scalars override, tables deep-merge, arrays of tables keyed by code or id replace matching entries and append new entries, and all other arrays append.

Step 2: Execute Prepend Steps

Execute each entry in {workflow.activation_steps_prepend} in order before proceeding.

Step 3: Load Persistent Facts

Treat every entry in {workflow.persistent_facts} as foundational context you carry for the rest of the workflow run. Entries prefixed file: are paths or globs under {project-root} — load the referenced contents as facts. All other entries are facts verbatim.

Step 4: Load Config

Load config from {project-root}/_bmad/bmm/config.yaml and resolve:

  • Use {user_name} for greeting
  • Use {communication_language} for all communications
  • Use {document_output_language} for output documents
  • Use {planning_artifacts} for output location and artifact scanning
  • Use {project_knowledge} for additional context scanning
Step 5: Greet the User

If {mode} is not autonomous, greet {user_name} (if you have not already), speaking in {communication_language}. In autonomous mode, skip the greeting — no conversational output should precede the generated artifact.

Step 6: Execute Append Steps

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

Activation is complete. Begin the workflow at Stage 1 below.

Stage 1: Understand Intent

Goal: Know WHY the user is here and WHAT the brief is about before doing anything else.

Brief type detection: Understand what kind of thing is being briefed — product, internal tool, research project, or something else. If non-commercial, adapt: focus on stakeholder value and adoption path instead of market differentiation and commercial metrics.

Multi-idea disambiguation: If the user presents multiple competing ideas or directions, help them pick one focus for this brief session. Note that others can be briefed separately.

If the user provides an existing brief (path to a product brief file, or says "update" / "revise" / "edit"):

  • Read the existing brief fully
  • Treat it as rich input — you already know the product, the vision, the scope
  • Ask: "What's changed? What do you want to update or improve?"
  • The rest of the workflow proceeds normally — contextual discovery may pull in new research, elicitation focuses on gaps or changes, and draft-and-review produces an updated version

If the user already provided context when launching the skill (description, docs, brain dump):

  • Acknowledge what you received — but DO NOT read document files yet. Note their paths for Stage 2's subagents to scan contextually. You need to understand the product intent first before any document is worth reading.
  • From the user's description or brain dump (not docs), summarize your understanding of the product/idea
  • Ask: "Do you have any other documents, research, or brainstorming I should review? Anything else to add before I dig in?"

If the user provided nothing beyond invoking the skill:

  • Ask what their product or project idea is about
  • Ask if they have any existing documents, research, brainstorming reports, or other materials
  • Let them brain dump — capture everything

The "anything else?" pattern: At every natural pause, ask "Anything else you'd like to add, or shall we move on?" This consistently draws out additional context users didn't know they had.

Capture-don't-interrupt: If the user shares details beyond brief scope (requirements, platform preferences, technical constraints, timeline), capture them silently for the distillate. Don't redirect or stop their flow.

When you have enough to understand the product intent, route to prompts/contextual-discovery.md with the current mode.
