CLI-Anything turns software and services into command-line interfaces that AI agents can use to perform tasks and produce artifacts. It is intended for people building or using agent workflows with tools such as coding assistants, design software, and other applications. The catalogue entries are skills, commands, a plugin, and a rule for working with CLI-Anything.
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.

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 | $0.00054 | $0.01349 |
| Opus 5.5 | $0.00022 | $0.00540 |
| Sonnet 5.5 | $0.00011 | $0.00270 |
| Haiku 4.5 | $0.00005 | $0.00135 |
Grade A, and why
cli-anything 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 1mo 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.
How it starts
The opening of the file, as written. The whole thing — 155 lines — stays where its author put it; the contents beside it link to each section on GitHub.
CLI-Anything for Codex
Use this skill when the user wants Codex to act like the CLI-Anything builder.
Read the Full Methodology First
Before implementation, use the full methodology source of truth:
- Read
references/HARNESS.mdrelative to this skill directory. - Read the matching mode specification under
references/commands/. - Read referenced files under
references/guides/only when they apply to the target. - If the installed resources are unavailable and this skill is being used from a
CLI-Anythingrepository checkout, read../cli-anything-plugin/HARNESS.mdand the resources around it. - If neither local source is available, clone or download
https://github.com/HKUDS/CLI-Anythingand usecli-anything-plugin/HARNESS.md. - Only if all full-methodology sources are unavailable, follow the condensed rules below.
The installer vendors the canonical resources from cli-anything-plugin/ into this
skill so a normal Codex installation is self-contained.

When reading vendored documents, apply these path remappings instead of resolving plugin paths against the current working directory:
What ships with it
4 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-anything is a skill published in the GitHub repository HKUDS/CLI-Anything (53,078 stars, last pushed 24d ago), licensed Apache-2.0. It adds 54 tokens to every session and 1,349 once invoked, about $0.0002 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 2026-08-30.
