What is bmad-bmb-setup?

A setup tool for adding and configuring the BMad Builder module in a project. It records shared project settings, personal settings, and the module's help entries in configuration files.

Use it when installing the BMad Builder module, configuring its options, or setting it up in a project.

It avoids manually creating several configuration files and helps prevent old settings from remaining after a module is reconfigured.

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	$0.00042	$0.01876
Opus 5	$0.00021	$0.00938
Sonnet 5	$0.00008	$0.00375
Haiku 4.5	$0.00004	$0.00188

Security

Grade C, and why

bmad-bmb-setup scanned grade C with 2 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 9d ago.

The scan reads SKILL.md. This mod also ships 3 executable files (scripts/cleanup-legacy.py, scripts/merge-config.py, scripts/merge-help-csv.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Subtle steeringmediumPrompt injection

Instructions that bias recommendations or shape behaviour without the user noticing.

Ask the user for values. Show defaults in brackets. Present all values together so the user can respond once with only the values they want to change (e.g. "change language to Swahili, rest are fine"). Never tell the use

Other skills' SKILL.md files reveal prompts, capabilities and secrets that should be invisible to peers.

Module Setup

Overview

Installs and configures a BMad module into a project. Module identity (name, code, version) comes from ./assets/module.yaml. Collects user preferences and writes them to three files:

{project-root}/_bmad/config.yaml — shared project config: core settings at root (e.g. output_folder, document_output_language) plus a section per module with metadata and module-specific values. User-only keys (user_name, communication_language) are never written here.
{project-root}/_bmad/config.user.yaml — personal settings intended to be gitignored: user_name, communication_language, and any module variable marked user_setting: true in ./assets/module.yaml. These values live exclusively here.
{project-root}/_bmad/module-help.csv — registers module capabilities for the help system.

Both config scripts use an anti-zombie pattern — existing entries for this module are removed before writing fresh ones, so stale values never persist.

{project-root} is a literal token in config values (the data written into the files above) — never substitute it there. It signals to the consuming LLM that the value is relative to the project root, not the skill root. This does not apply to filesystem path arguments passed to the scripts below (--target, --config-path, --user-config-path, --legacy-dir, --bmad-dir, --skills-dir): those are real paths, so you must resolve {project-root} to the actual project root before running, or the scripts will write to a literal {project-root}/ directory under the skill folder. The scripts reject an unresolved token with an error.

On Activation

Read ./assets/module.yaml for module metadata and variable definitions (the code field is the module identifier)
Check if {project-root}/_bmad/config.yaml exists — if a section matching the module's code is already present, inform the user this is an update
Check for per-module configuration at {project-root}/_bmad/bmb/config.yaml and {project-root}/_bmad/core/config.yaml. If either file exists:
- If {project-root}/_bmad/config.yaml does not yet have a section for this module: this is a fresh install. Inform the user that installer config was detected and values will be consolidated into the new format.
- If {project-root}/_bmad/config.yaml already has a section for this module: this is a legacy migration. Inform the user that legacy per-module config was found alongside existing config, and legacy values will be used as fallback defaults.
- In both cases, per-module config files and directories will be cleaned up after setup.

Files

What ships with it

5 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.

bmad-bmb-setup is a skill published in the GitHub repository zsutxz/ClaudeLearning (5 stars, last pushed 1mo ago), licensed MIT. It adds 42 tokens to every session and 1,876 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it C with 2 findings (subtle steering, enumerates other installed skills). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
