gum-completion-bash

A command that generates Bash shell autocompletion for the gum command-line tool. Shell autocompletion suggests available commands and options as you type.

In plain words

Use it to generate a completion script and load gum command suggestions in Bash.
Why use it?
It avoids having to remember or type every gum subcommand and option, making repeated terminal use quicker.

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.

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

gum-completion-bash 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

gum completion bash

Generated from gum schema --json. Do not edit this page by hand; run make docs-commands.

Generate the autocompletion script for the bash shell.

This script depends on the 'bash-completion' package. If it is not installed already, you can install it via your OS's package manager.

To load completions in your current shell session:

source <(gum completion bash)

To load completions for every new session, execute once:

Linux:
gum completion bash > /etc/bash_completion.d/gum
macOS:
gum completion bash > $(brew --prefix)/etc/bash_completion.d/gum

You will need to start a new shell for this setup to take effect.

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.
