parallel-cli

A workflow for running several independent command-line checks at the same time. Command-line checks are terminal commands used to inspect code, files, or an environment.

In plain words
What is it for?
Use it for parallel repository or environment checks that do not modify files or depend on one another.
Why use it?
It shortens inspection time when checks are limited by waiting for file or system input rather than by complex reasoning.

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

parallel-cli 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 2d 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

Parallel CLI

Use multiple independent CLI checks in parallel when the question is bottlenecked on I/O rather than reasoning.

Use when

  • Several bounded shell checks can run at the same time.
  • You want faster repository or environment inspection without changing behavior.

Workflow

  1. Split only independent commands into parallel work.
  2. Keep each command narrow and easy to interpret.
  3. Recombine the results into one clear conclusion.
  4. Avoid parallel writes or destructive operations.
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.

parallel-cli is a skill published in the GitHub repository aaronnat23/disp8ch (98 stars, last pushed 1mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 97 tokens. 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 2026-08-30.
