What is teststand-rules?

A set of working rules for editing NI TestStand sequence files, which describe automated test procedures. The rules cover building, changing, copying, comparing, rebuilding, and checking sequence files through TestStand tools.

It is for creating sequences from flowcharts or descriptions, editing steps and properties, adding conditions and loops, migrating or cloning files, and verifying changes.

It prevents common mistakes such as using fragile control flow or accepting an incomplete file comparison as proof that a rebuild is correct. It also explains restrictions around LabVIEW module files.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add Zuehlke/teststand-mcp --skill teststand-rules

Clone the repo

git clone --depth 1 https://github.com/Zuehlke/teststand-mcp

Made for: Claude Code.

Or install teststand-mcp, the plugin that ships this one along with the rest of its 1 skill, 2 hooks, 1 MCP server.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00120	$0.00514
Opus 5.5	$0.00048	$0.00206
Sonnet 5.5	$0.00024	$0.00103
Haiku 4.5	$0.00012	$0.00051

Security

Grade A, and why

teststand-rules 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

TestStand rules

Never do

Never run the teststand-sequence-builder as a subagent. Run its workflow in the main thread: its per-step AskUserQuestion prompts do not work in a subagent, and every step silently degrades to a plain Statement placeholder.
Never use Goto or Label for control flow. Use the NI_Flow_* step types (NI_Flow_If, NI_Flow_While, NI_Flow_For, NI_Flow_Select, ...): they are structured and survive later edits.
Never load a .lvlibp pane by any route: the in-process load kills the server and the isolated worker only times out. Clone it with copy_step_module or the import_sequence_file default.
Never accept a rebuild on the diff alone. Run diff_sequence_files for the content AND audit_type_consistency for the type registry (the file's type definitions with their attach state); the diff cannot see type conflicts.

Files

What ships with it

5 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

teststand-rules is a skill published in the GitHub repository Zuehlke/teststand-mcp (34 stars, last pushed yesterday), licensed MIT. It adds 120 tokens to every session and 514 once invoked, about $0.0005 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-10-29.
