MoAI-ADK is a Go-based harness that organizes and verifies Claude Code work across planning, implementation, synchronization, and review stages. Developers use it to structure agentic coding tasks, apply quality gates, and route work across language models, while the catalogue entries extend its workflow with skills, hooks, commands, MCP servers, instructions, and settings.
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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00055 | $0.03068 |
| Opus 5 | $0.00028 | $0.01534 |
| Sonnet 5 | $0.00011 | $0.00614 |
| Haiku 4.5 | $0.00006 | $0.00307 |
Grade A, and why
moai-foundation-cc 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 12d 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

Quick Reference
Skills: Model-invoked extensions in ~/.claude/skills/ (personal) or .claude/skills/ (project). Three-level progressive disclosure. Max 500 lines.
Sub-agents: Specialized assistants via Agent(subagent_type="..."). Context window follows the session model (Sonnet 5 = 1M native on the Anthropic API; Haiku / gateway / older models = 200K — CC 2.1.197). Nesting: a subagent can spawn nested subagents only when its tools list includes Agent (CC 2.1.172); MoAI retained agents omit Agent, so they do not nest. To create or manage subagents, ask Claude or edit .claude/agents/ directly — the /agents wizard was removed in CC 2.1.198 (the official sub-agents doc still documented a /agents tabbed interface as of 2026-07-03; doc lag — verify in a live 2.1.198 session).

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.
- 12d ago First seen · 299 lines · 55 tokens per session scan A 2a350cbd5102
moai-foundation-cc is a skill published in the GitHub repository modu-ai/moai-adk (1,207 stars, last pushed today), licensed Apache-2.0. It adds 55 tokens to every session and 3,068 once invoked, about $0.0003 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.
