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 | $0.04703 | $0.04703 |
| Opus 5 | $0.02351 | $0.02351 |
| Sonnet 5 | $0.00941 | $0.00941 |
| Haiku 4.5 | $0.00470 | $0.00470 |
Grade A, and why
agcluster-container CLAUDE.md scanned grade A with 1 finding 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 7d 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.

Not a fault in itself. Listed so you know the mod talks to something, and to what.

Project Overview
AgCluster Container is a containerized runtime for Claude Agent SDK instances with a REST API for managing agent sessions. It allows Claude agents to run in isolated Docker containers with configurable tools and resources, accessible via Web UI and HTTP API.
Key Concept: Users bring their own Anthropic API keys (BYOK), and AgCluster creates persistent Docker containers per conversation running Claude SDK agents with configurable tools and resources. The system supports preset agent configurations (code-assistant, research-agent, data-analysis, fullstack-team) and custom inline configs. Containers are reused across messages in the same conversation thread, maintaining context.
Architecture
Web UI / API Client
↓ POST /api/agents/launch (create session with config)
↓ POST /api/agents/{session_id}/chat (send messages)
AgCluster API (FastAPI)
↓ Creates Docker container with session
↓ HTTP communication (http://{container_ip}:3000)
Agent Container (Claude SDK)
↓ ClaudeSDKClient initialized with session ID
↓ Executes tools in /workspace
↓ Streams responses via HTTP
AgCluster API
↓ Streams Claude SDK events as JSON
↓ Returns to client
Session Management Flow
Container Startup
↓
AgentServer.__init__()
↓
AgentServer.initialize_sdk()
↓ Creates ClaudeSDKClient(options)
↓ Enters context manager (session created)
↓ Session ID: e.g., "b28c5a6a-0f94-4840-8eb9-34f5e69c0641"
↓
WebSocket Server Ready
↓
[Query 1] client.query() → client.receive_messages()
[Query 2] client.query() → client.receive_messages() [same session]
[Query N] client.query() → client.receive_messages() [same session]
↓
Container Shutdown
↓
SDK context manager cleanup

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.

agcluster-container CLAUDE.md is an instructions file published in the GitHub repository whiteboardmonk/agcluster-container (77 stars, last pushed 9mo ago), licensed MIT. It adds 4,703 tokens to every session, about $0.0235 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
