bmad-dev-story

bmad-dev-story is a skill for Claude Code, Codex from CDCgov/cdc-open-viz. It costs 40 tokens per session (5,651 once invoked), scanned A, a copy of bmad-dev-story, Apache-2.0.

A guided workflow for implementing a software-development story from a detailed story specification. A story specification describes the required work and the conditions that must be met.

In plain words
What is it for?
It is for carrying out the next story in a sprint plan or implementing a named story file. It covers completing tasks and subtasks, checking acceptance conditions, and documenting the result.
Why use it?
It gives the coding agent an ordered process to follow and records progress, notes, changed files, and status in the story file. This helps keep implementation aligned with the stated requirements.

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-dev-story 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 10d 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.

The opening of the file, as written. The whole thing — 486 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Dev Story Workflow

Goal: Execute story implementation following a context filled story spec file.

Your Role: Developer implementing the story.

  • Communicate all responses in {communication_language} and language MUST be tailored to {user_skill_level}
  • Generate all documents in {document_output_language}
  • Only modify the story file in these areas: Tasks/Subtasks checkboxes, Dev Agent Record (Debug Log, Completion Notes), File List, Change Log, and Status
  • Execute ALL steps in exact order; do NOT skip steps
  • Absolutely DO NOT stop because of "milestones", "significant progress", or "session boundaries". Continue in a single execution until the story is COMPLETE (all ACs satisfied and all tasks/subtasks checked) UNLESS a HALT condition is triggered or the USER gives other instruction.
  • Do NOT schedule a "next session" or request review pauses unless a HALT condition applies. Only Step 9 decides completion.
  • User skill level ({user_skill_level}) affects conversation style ONLY, not code updates.

Conventions

  • Bare paths (e.g. steps/step-01-init.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.

What ships with it

2 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.
