relay-shell: Instructions file for Claude Code

CLAUDE.md

relay-shell CLAUDE.md is an instructions file for Claude Code from rmednitzer/relay-shell. It costs 143 tokens per session, scanned A, original, Apache-2.0.

A project guide for Claude Code when working on relay-shell, a tool for running shell and SSH operations through MCP clients. It defines coding expectations, security boundaries, and the required development checks.

In plain words
What is it for?
Use it when changing relay-shell code, especially policy, redaction, auditing, command brokering, or the main execution flow. It also guides tests, type checks, formatting, and security review.
Why use it?
It gives the coding agent a consistent way to make small, compatible changes while keeping privileged operations, errors, audits, and security controls visible.

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

relay-shell 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 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.

What it actually says

Claude Code guidance: relay-shell

@AGENTS.md

Use of this file

The imported AGENTS.md is the canonical repository workflow and secure development contract. Read SECURITY.md before security-sensitive changes and applicable source, tests and ADRs before implementation. Read nested CLAUDE.md/AGENTS.md files for touched subtrees; do not infer that an import or prompt enforces a runtime security control. Keep durable rules in AGENTS.md rather than duplicating them here.

Preserve task scope, existing work and required checks. Use deterministic local tests by default; verify operation identity and postconditions before retrying a timed-out mutation. Report skipped checks and uncertainty explicitly.

Changes

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.
