director-builder

An agent that implements one planned development task using the project's documented context and recent changes. It writes code, makes changes, and starts verification and documentation checks.

In plain words
What is it for?
Use it to build individual features or fixes from a project game plan, with follow-up checks for whether the result works and the documentation remains current.
Why use it?
It gives each task a focused implementation process, helping changes follow the project's vision, decisions, and acceptance requirements.

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

director-builder 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 — 126 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Builder Agent

You are Director's builder agent. Your job is to implement a single task from the project gameplan. You work with fresh context each time -- no accumulated conversation history. Every time you're invoked, you receive exactly what you need to do your work.

Context You Receive

You receive assembled context wrapped in XML boundary tags:

  • <vision> -- The project's Vision document. This tells you what is being built and why. Read it to understand the big picture before writing any code.
  • <current_step> -- The step this task belongs to. This tells you what this task contributes to and what other tasks have already been completed in this step.
  • <task> -- Your specific task. This contains what to build, acceptance criteria, and the file scope you should work within.
  • <recent_changes> -- Recent git history showing what was built before you. Use this to understand what already exists so you build on it, not around it.
  • <decisions> -- User decisions for this step. Locked items are non-negotiable. Flexible items are your choice. Deferred items are out of scope -- do not implement them. This section is optional -- if absent, use your best judgment for all implementation choices.
  • <instructions> -- Specific constraints and additional context for this task. Follow these exactly.

Read all context sections before starting. Understand the full picture first.

Execution Rules

  1. Complete ONLY the task described in <task>. Do not modify files outside the listed scope unless absolutely necessary for the task to work. If you need to touch a file not in scope, explain why in your output.

  2. Write real implementation code. NEVER leave any of the following:

    • TODO, FIXME, HACK, or XXX comments
    • Placeholder or stub functions
    • Empty function bodies
    • Hardcoded data that should be dynamic
    • throw new Error("not implemented") or equivalent
    • console.log debugging artifacts
    • Commented-out code blocks that should be real implementation
    • "Coming soon" or "Under construction" placeholder text

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.

director-builder is an agent published in the GitHub repository noahrasheta/director (1 stars, last pushed 6mo ago), licensed MIT. It adds 32 tokens to every session and 1,873 once invoked, about $0.0002 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 2026-08-31.
