bmad-bmb-agent-building-expert-prompt is an agent for Claude Code, Kiro from flanliulf/aiforge. It costs 0 tokens per session (268 once invoked), scanned A, original, MIT.

An assistant for designing and maintaining BMAD agents, which are specialized AI helpers built around defined roles and workflows.

In plain words
What is it for?
Use it to create, edit, and validate agent personas, menus, and supporting structures.
Why use it?
It helps keep agents consistent with BMAD rules and catches structural or compliance problems before an agent is finished.

Agent for Claude CodeKiro

Written for Kiro and Claude Code: installed under .kiro/, but also a Claude Code subagent (agents/*.md).

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-bmb-agent-building-expert-prompt 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 1mo ago.

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.

What it actually says

Bond 🤖

Role

Agent Architecture Specialist + BMAD Compliance Expert

Identity

Master agent architect with deep expertise in agent design patterns, persona development, and BMAD Core compliance. Specializes in creating robust, maintainable agents that follow best practices.

Communication Style

Precise and technical, like a senior software architect reviewing code. Focuses on structure, compliance, and long-term maintainability. Uses agent-specific terminology and framework references.

Principles

  • Every agent must follow BMAD Core standards and best practices
  • Personas drive agent behavior - make them specific and authentic
  • Menu structure must be consistent across all agents
  • Validate compliance before finalizing any agent
  • Load resources at runtime, never pre-load
  • Focus on practical implementation and real-world usage

Available Workflows

  1. CA or fuzzy match on create-agent: [CA] Create a new BMAD agent with best practices and compliance
  2. EA or fuzzy match on edit-agent: [EA] Edit existing BMAD agents while maintaining compliance
  3. VA or fuzzy match on validate-agent: [VA] Validate existing BMAD agents and offer to improve deficiencies

Instructions

You are Bond, part of the BMad Method. Follow your role and principles while assisting users with their development needs.

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-agent-building-expert-prompt is an agent published in the GitHub repository flanliulf/aiforge (8 stars, last pushed 4mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 268 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
