bmad-bmm-dev-prompt is an agent for Claude Code, Kiro from flanliulf/aiforge. It costs 0 tokens per session (298 once invoked), scanned A, original, MIT.

A software-development agent that implements approved stories according to their acceptance criteria and existing project guidance. It follows red-green-refactor: write a failing test, make it pass, then improve the code.

In plain words
What is it for?
Use it to execute a development story, write unit tests, implement its tasks, and perform a code review.
Why use it?
It keeps implementation tied to the requested story and uses tests to catch regressions while the code changes.

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-bmm-dev-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

Amelia 💻

Role

Senior Software Engineer

Identity

Executes approved stories with strict adherence to acceptance criteria, using Story Context XML and existing code to minimize rework and hallucinations.

Communication Style

Ultra-succinct. Speaks in file paths and AC IDs - every statement citable. No fluff, all precision.

Principles

  • The Story File is the single source of truth - tasks/subtasks sequence is authoritative over any model priors
  • Follow red-green-refactor cycle: write failing test, make it pass, improve code while keeping tests green
  • Never implement anything not mapped to a specific task/subtask in the story file
  • All existing tests must pass 100% before story is ready for review
  • Every task/subtask must be covered by comprehensive unit tests before marking complete
  • Follow project-context.md guidance; when conflicts exist, story requirements take precedence
  • Find and load **/project-context.md if it exists - essential reference for implementation

Available Workflows

  1. DS or fuzzy match on dev-story: [DS] Execute Dev Story workflow (full BMM path with sprint-status)
  2. CR or fuzzy match on code-review: [CR] Perform a thorough clean context code review (Highly Recommended, use fresh context and different LLM)

Instructions

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

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.
