What it does

Bmad Code Review is an agent skill from delorenj/mcp-server-trello. Adversarial code review using parallel review layers and structured triage. Use when the user says "run code review" or "review this code"

Its SKILL.md is about 1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 6 other files (for example `steps/step-01-gather-context.md`, `steps/step-02-review.md` and `steps/step-03-triage.md`).

It sits in Development, covering Code review. 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 says run code review
  • Review this code

Example prompts

  • “run code review”
  • “review this code”
  • “/bmad-code-review”

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 Code Review loads about 1k tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 462 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
~1k

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.

Adversarial code review using parallel review layers and structured triage. Use when the user says "run code review" or "review this code"

Code Review Workflow

Goal: Review code changes adversarially. No noise, no filler.

Subagents, when the capability is available, are an important part of this workflow. Use them as directed by the workflow steps. If you need an explicit user instruction to run them, ask once now for the whole workflow run.

Conventions

  • Bare paths (e.g. checklist.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.

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:

  • project_name, planning_artifacts, implementation_artifacts, user_name
  • communication_language, document_output_language, user_skill_level
  • date as system-generated current datetime
  • sprint_status = {implementation_artifacts}/sprint-status.yaml
  • project_context = **/project-context.md (load if exists)
  • YOU MUST ALWAYS SPEAK OUTPUT in your Agent communication style with the config {communication_language}
Step 5: Greet the User

Greet {user_name}, speaking in {communication_language}.

Show full SKILL.md (182 more words)Show less
Step 6: Execute Append Steps

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.

WORKFLOW ARCHITECTURE

This uses step-file architecture for disciplined execution:

  • Micro-file Design: Each step is self-contained and followed exactly
  • Just-In-Time Loading: Only load the current step file
  • Sequential Enforcement: Complete steps in order, no skipping
  • State Tracking: Persist progress via in-memory variables
  • Append-Only Building: Build artifacts incrementally
Step Processing Rules
  1. READ COMPLETELY: Read the entire step file before acting
  2. FOLLOW SEQUENCE: Execute sections in order
  3. WAIT FOR INPUT: Halt at checkpoints and wait for human
  4. LOAD NEXT: When directed, read fully and follow the next step file
Critical Rules (NO EXCEPTIONS)
  • NEVER load multiple step files simultaneously
  • ALWAYS read entire step file before execution
  • NEVER skip steps or optimize the sequence
  • ALWAYS follow the exact instructions in the step file
  • ALWAYS halt at checkpoints and wait for human input

FIRST STEP

Read fully and follow: ./steps/step-01-gather-context.md
