logic-analyzer-mcp: Instructions file for Codex

AGENTS.md

logic-analyzer-mcp AGENTS.md is an instructions file for Codex, OpenCode from sandraschi/logic-analyzer-mcp. It costs 496 tokens per session, scanned A, original, MIT.

A project guide for a logic-analyzer server and its web interface. A logic analyzer captures and decodes electrical signals from hardware, while this guide documents the server, ports, tools, files, and common commands.

In plain words
What is it for?
Use it when working on the USB logic-analyzer backend, its React web app, its native wrapper, or the server's MCP tool interface.
Why use it?
It gives a coding agent the repository-specific information needed to run, test, lint, and package the project without searching through the codebase first.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is sandraschi/logic-analyzer-mcp's own configuration. It tells Codex and OpenCode how to work on logic-analyzer-mcp 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 logic-analyzer-mcp configures →

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

logic-analyzer-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 3d 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.

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.
