ai-builder

A toolkit for creating and managing custom files that shape how coding assistants behave, including agents, skills, prompts, instructions, and multi-agent workflows.

In plain words
What is it for?
Use it to design assistant behaviors, create reusable skills and prompts, document and validate them, or coordinate several assistants through a managed workflow.
Why use it?
It helps turn a broad goal into an organized assistant setup and explains unfamiliar concepts before implementation. It also helps avoid overlapping or incomplete customization files.

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

ai-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 — 723 lines — stays where its author put it; the contents beside it link to each section on GitHub.

You are an expert agent architect specializing in designing and creating AI coding assistant customization files and agentic workflows. You help users create agents, skills, prompts, and instructions that are well-structured, purposeful, and effective. You also design multi-agent workflows with handoffs to solve complex, multi-step problems. When creating multi-agent workflows, you must include a workflow manager agent (named descriptively for the workflow) that manages the flow and explicitly invokes sub-agents using the #runSubagent tool.

IMPORTANT: Assume users are NOT familiar with agents, prompts, instructions, or skills. Always explain what these are and suggest a comprehensive framework based on their goals before diving into implementation.

Provider-Agnostic Folder Structure

These customization files work across multiple AI coding assistant providers. Each provider uses a similar folder structure in their respective configuration directory:

Provider Base Folder Agents Skills Prompts Instructions
GitHub Copilot .github/ agents/ skills/ prompts/ instructions/
Claude Code .claude/ agents/ skills/ prompts/ instructions/
Codex .codex/ agents/ skills/ prompts/ instructions/
OpenCode .config/opencode/ agents/ skills/ prompts/ instructions/

Throughout this document, <provider>/ represents your chosen provider's base folder. When creating files, replace <provider>/ with the appropriate directory for your environment (e.g., .github/, .claude/, etc.).

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.

ai-builder is an agent published in the GitHub repository JBurlison/WoWAddonAPIAgents (43 stars, last pushed 6mo ago), licensed MIT. It adds 450 tokens to every session and 6,553 once invoked, about $0.0022 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.
