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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00033 | $0.00196 |
| Opus 5 | $0.00016 | $0.00098 |
| Sonnet 5 | $0.00007 | $0.00039 |
| Haiku 4.5 | $0.00003 | $0.00020 |
Grade A, and why
ac-master-controller 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 11d 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.
This is a copy
100% identical to ac-master-controller — 0 lines differ, which has more behind it and is treated as the original. This page carries a canonical link to it rather than competing with it.
What it actually says
AC Master Controller
Master controller for end-to-end autonomous coding.
Purpose
Provides the highest-level interface for autonomous coding, managing complete project implementations from spec to completion.
Quick Start
from scripts.master_controller import MasterController
controller = MasterController(project_dir)
result = await controller.run_project(
spec="Build a REST API with user authentication",
objective="Complete API implementation"
)
Complete Workflow
1. SETUP → Initialize project and config
2. SPEC → Generate feature list from spec
3. LOOP → Run autonomous implementation loop
4. VERIFY → Final validation
5. REPORT → Generate completion report
API Reference
See scripts/master_controller.py for full implementation.
What ships with it
1 file 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.
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.
