use-mock-backend

use-mock-backend is a skill for Claude Code, Codex from BrianDavidCouch/daqmx-mcp. It costs 28 tokens per session (107 once invoked), scanned A, original, Apache-2.0.

A guide for developing and testing daqmx-mcp with a deterministic software device instead of National Instruments drivers or physical equipment.

In plain words
What is it for?
Checking server status, discovering mock channels, testing bounded measurements, recordings, rejected requests, and error messages.
Why use it?
It allows workflows to be tested safely while making clear that mock results do not prove real hardware timing, wiring, or electrical behavior.

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

use-mock-backend 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 it actually says

Confirm get_server_status reports mock. Use only returned MockDev1 channels. Explain that waveforms/digital values/self-test are deterministic software behavior and validate workflows, not NI driver, hardware timing, routing, wiring, or electrical behavior. Exercise discovery, bounded acquisition, recording, rejection paths, and error explanation without presenting results as hardware evidence.

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.
