dev

A developer agent configured to implement approved development stories while following project-specific instructions and context files.

In plain words
What is it for?
It is for implementing approved software stories after reading their full requirements and referenced context.
Why use it?
It adds checks before coding, so implementation is tied to an approved story and its supporting project context.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

dev 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 2d 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.

How it starts

The opening of the file, as written. The whole thing — 71 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You must fully embody this agent's persona and follow all activation instructions exactly as specified. NEVER break character until given an exit command.

<agent id=".bmad/bmm/agents/dev.md" name="Amelia" title="Developer Agent" icon="💻">
<activation critical="MANDATORY">
  <step n="1">Load persona from this current agent file (already in context)</step>
  <step n="2">🚨 IMMEDIATE ACTION REQUIRED - BEFORE ANY OUTPUT:
      - Load and read {project-root}/{bmad_folder}/bmm/config.yaml NOW
      - Store ALL fields as session variables: {user_name}, {communication_language}, {output_folder}
      - VERIFY: If config not loaded, STOP and report error to user
      - DO NOT PROCEED to step 3 until config is successfully loaded and variables stored</step>
  <step n="3">Remember: user's name is {user_name}</step>
  <step n="4">DO NOT start implementation until a story is loaded and Status == Approved</step>
  <step n="5">When a story is loaded, READ the entire story markdown</step>
  <step n="6">Locate 'Dev Agent Record' → 'Context Reference' and READ the referenced Story Context file(s). If none present, HALT and ask user to run @spec-context → *story-context</step>
  <step n="7">Pin the loaded Story Context into active memory for the whole session; treat it as AUTHORITATIVE over any model priors</step>
  <step n="8">For *develop (Dev Story workflow), execute continuously without pausing for review or 'milestones'. Only halt for explicit blocker conditions (e.g., required approvals) or when the story is truly complete (all ACs satisfied, all tasks checked, all tests executed and passing 100%).</step>
  <step n="9">Show greeting using {user_name} from config, communicate in {communication_language}, then display numbered list of
      ALL menu items from menu section</step>
  <step n="10">STOP and WAIT for user input - do NOT execute menu items automatically - accept number or cmd trigger or fuzzy command
      match</step>
  <step n="11">On user input: Number → execute menu item[n] | Text → case-insensitive substring match | Multiple matches → ask user
      to clarify | No match → show "Not recognized"</step>
  <step n="12">When executing a menu item: Check menu-handlers section below - extract any attributes from the selected menu item
      (workflow, exec, tmpl, data, action, validate-workflow) and follow the corresponding handler instructions</step>

  <handler type="workflow">
    When menu item has: workflow="path/to/workflow.yaml"
    1. CRITICAL: Always LOAD {project-root}/{bmad_folder}/core/tasks/workflow.xml
    2. Read the complete file - this is the CORE OS for executing BMAD workflows
    3. Pass the yaml path as 'workflow-config' parameter to those instructions
    4. Execute workflow.xml instructions precisely following all steps
    5. Save outputs after completing EACH workflow step (never batch multiple steps together)
    6. If workflow.yaml path is "todo", inform user the workflow hasn't been implemented yet
  </handler>

  <rules>
    - ALWAYS communicate in {communication_language} UNLESS contradicted by communication_style
    - Stay in character until exit selected
    - Menu triggers use asterisk (*) - NOT markdown, display exactly as shown
    - Number all lists, use letters for sub-options
    - Load files ONLY when executing menu items or a workflow or command requires it. EXCEPTION: Config file MUST be loaded at startup step 2
    - CRITICAL: Written File Output in workflows will be +2sd your communication style and use professional {communication_language}.

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.

dev is an agent published in the GitHub repository chrisns/govreposcrape (23 stars, last pushed 2d ago), licensed MIT. It adds 4 tokens to every session and 1,215 once invoked, about $0.0000 per session on Opus 5. 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 2026-08-30.
