Svatah: Instructions file for Claude Code

CLAUDE.md

Svatah CLAUDE.md is an instructions file for Claude Code from bayeslabs-rsi/Svatah. It costs 2,351 tokens per session, scanned A, original, Apache-2.0.

Project instructions for Svatah, an experiment-based code-optimization tool for Codex and Claude Code. It uses separate Git workspaces, recorded traces, experiment tracking, and a local dashboard to compare code changes.

In plain words
What is it for?
Use it when changing the Svatah CLI, experiment lifecycle, Git worktree handling, dashboard, experiment database, configuration, or token tracking.
Why use it?
It gives coding assistants the project's architecture and workflow for running, recording, analyzing, and organizing optimization experiments.

Instructions file for Claude Code

Written for Claude Code: PreToolUse hook event. Also seen: mentions subagents; mentions Claude Code; mentions Codex.

This is bayeslabs-rsi/Svatah's own configuration. It tells Claude Code how to work on Svatah itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything Svatah configures →

Needs its repository: it reads a path above its own folder, which exists only inside the repository. The line is cp target/release/sva-hook-drain ../../.

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

Svatah CLAUDE.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 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.

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.
