run-local-command-check

run-local-command-check is a skill for Claude Code, Codex from joinwell52-AI/CodeFlowMu-open. It costs 39 tokens per session (313 once invoked), scanned A, original, MIT.

Instructions for safely running local commands used for checks such as tests, builds, type checks and diagnostics. They require reporting the exact command, location and result.

In plain words
What is it for?
Choosing focused commands, capturing important output, reporting failures or skipped checks and documenting follow-up risks after local verification.
Why use it?
They make verification evidence clear and prevent an agent from claiming a check passed when it was not run or failed.

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

run-local-command-check 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 5d 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

Run Local Command Check

When to use

Use before running commands that produce evidence for a task, especially tests, typechecks, builds, local scripts, CLI diagnostics, or health checks.

Rules

  • State the command purpose before relying on its output.
  • Prefer the smallest command that verifies the claim.
  • Run commands from the correct workspace directory.
  • Capture the command, exit status, and key output.
  • Treat failure output as evidence, not as something to hide.
  • Do not claim success if a command failed or was not run.
  • Avoid destructive commands unless the task explicitly authorizes them.

Required output

When reporting, include:

  • Command.
  • Working directory.
  • Result: pass, fail, skipped, or blocked.
  • Key output lines or a concise summary.
  • Any follow-up risk from skipped checks.

Forbidden actions

  • Do not fabricate command output.
  • Do not run broad or slow checks when a narrow check is enough unless risk justifies it.
  • Do not use command success alone as proof of UI or product correctness when browser or manual behavior matters.

Minimal example

Command: npm --prefix packages/codeflowmu-runtime test
Purpose: verify runtime unit tests after router change
Result: pass
Evidence: 280 tests passed, 0 failed
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.
