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 | $0.00855 | $0.00855 |
| Opus 5 | $0.00428 | $0.00428 |
| Sonnet 5 | $0.00171 | $0.00171 |
| Haiku 4.5 | $0.00085 | $0.00085 |
Grade A, and why
black-souls-mcp AGENTS.md 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 9d 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.

Repository Guidelines
Project Structure & Module Organization
src/ contains the strict TypeScript MCP server: index.ts defines the public tools and stable response envelope; bridge.ts owns the versioned file protocol, snapshot validation, input queue, and runtime lifecycle; config.ts resolves environment-controlled paths; and game.ts handles game discovery, integrity and save metadata, and process launch. Compiled output goes to dist/ and should not be edited. The in-game RGSS3 component is rgss/BlackSoulsBridge.rb. Keep server/package versions, BRIDGE_PROTOCOL, action names, and command limits synchronized across the TypeScript and RGSS3 sides. memory.ts implements the persistent AI memory layers (scratchpad, long-term knowledge, goals, session log); navigation.ts and battle.ts provide high-level pathfinding, interaction, and battle helpers. Test and maintenance utilities live in scripts/; PowerShell setup, verification, rollback, and uninstall entry points remain at the repository root. Architecture and setup details live in the README files, sample configuration in examples/, and the eval runner plus scenarios in evals/ (evals/results/ stays untracked). runtime/ is local generated state and must stay untracked.

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.
