cli-tools

A guide for working with command-line tools: programs you run from a terminal, such as ripgrep, jq, or bat.

In plain words
What is it for?
Use it to find missing programs, install tools with package managers such as Homebrew or apt, audit the environment, and update groups of tools.
Why use it?
It helps when a terminal command is missing, when tools need installing or updating, or when a project’s command-line environment needs checking.

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

cli-tools scanned grade A with 1 finding 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 yesterday.

The scan reads SKILL.md. This mod also ships 24 executable files (scripts/auto_update.sh, scripts/check_environment.sh, scripts/detect_project_type.sh, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Asks for rootlowPrivilege escalation

A mod that escalates privileges can change anything on the machine, not only the project.

| No sudo | `cargo install`, `pip install --user`, manual binary; on Debian/Ubuntu `apt-get download` + `dpkg -x` |

Downgraded: this mod is about security review, or the phrase is quoted, so it is likely naming the pattern rather than instructing it.

What ships with it

29 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.

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.

cli-tools is a skill published in the GitHub repository netresearch/cli-tools-skill (6 stars, last pushed 4d ago), with no licence file. It adds 71 tokens to every session and 918 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (asks for root). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
