agent-builder

agent-builder is a skill for Claude Code from aAAaqwq/AGI-Super-Team. It costs 0 tokens per session (867 once invoked), scanned A, original, MIT.

A toolkit for building a software agent from a written specification, including its code, settings, documentation, tests, and background launch setup.

In plain words
What is it for?
Use it to implement an agent for a specific process, especially one that reads or writes CSV data, uses the Claude command-line tool, changes customer or project records, or needs human approval.
Why use it?
It gives developers a defined structure for turning a process description into a runnable agent with logging, testing, dry-run mode, and optional notifications.

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

agent-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 8d 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.

Agent Builder

Takes a spec from Process Analyst and implements the agent: code, skill, config, launchd.

When to use

  • After Process Analyst has created a spec
  • "build an agent for process X"
  • "implement spec Y"

Input

Spec file from $AGENTS_PATH/specs/[name].spec.md

How to execute

Step 1: Read the spec

  • Read the spec file completely
  • Read the reference implementation: Email Pipeline ($GOOGLE_TOOLS_PATH/email_agent.py)
  • Understand the pipeline: trigger → steps → output

Step 2: Define architecture

Based on the spec, define:

agents/[name]/
├── [name]_agent.py        ← Main agent script
├── config.json            ← Configuration (paths, params)
├── README.md              ← Documentation
└── test_[name].py         ← Tests

Build rules:

  1. One file = one step (if step is complex) or one file = entire pipeline (if simple)
  2. Claude CLI for AI — use claude -p --model [model] instead of API key
  3. CSV for data — read/write via pandas or csv module
  4. Git auto-commit — if agent modifies CRM/PM data
  5. Telegram notification — if human approval is needed
  6. Dry-run mode — mandatory --dry-run flag
  7. Logging — stdout for launchd, file for debug
  8. Idempotency — re-run must not duplicate data

Step 3: Build

For each step from the spec:

  1. Write the function/script
  2. Handle errors according to the spec
  3. Add logging
  4. Add dry-run branch

Step 4: Create skill

Create skill file skills/agents/[name]-run.md with instructions on how to run the agent manually.

Step 5: Create launchd plist (if scheduled)

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "...">
<plist version="1.0">
<dict>
    <key>Label</key>

        <string>$AGENTS_PATH/[name]/[name]_agent.py</string>
    </array>
    <key>StartInterval</key>
    <integer>[seconds]</integer>
    <key>StandardOutPath</key>

</dict>

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.

agent-builder is a skill published in the GitHub repository aAAaqwq/AGI-Super-Team (91 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 867 tokens. 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.
