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.

SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high YARA Match · line 16 YARA rule matched a known malware signature (reverse shell, backdoor, ransomware, C2 framework, or info stealer).Fix: Remove the malware payload or compromised file entirely. Investigate how it entered the skill and audit all other artifacts for additional indicators of compromise.
- medium Privilege Escalation · line 25 Commands invoke sudo or root privileges. Verify this elevated access is necessary and justified.Fix: Avoid sudo/root unless strictly required. Prefer least-privilege patterns. If elevation is needed, document the justification and scope.
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 | $0.00049 | $0.01892 |
| Opus 5 | $0.00024 | $0.00946 |
| Sonnet 5 | $0.00010 | $0.00378 |
| Haiku 4.5 | $0.00005 | $0.00189 |
Grade A, and why
cli-anything-calibre 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 8d 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 — 281 lines — stays where its author put it; the contents beside it link to each section on GitHub.
cli-anything-calibre
A stateful CLI harness for Calibre e-book management. Wraps the real Calibre tools (calibredb, ebook-convert, ebook-meta) to give AI agents and scripts a clean, structured interface for library operations, metadata editing, and format conversion.
Installation
This CLI is installed as part of the cli-anything-calibre package:
pip install git+https://github.com/HKUDS/CLI-Anything.git#subdirectory=calibre/agent-harness
Prerequisites:
- Python 3.10+
- Calibre must be installed on your system (hard dependency)
# Debian/Ubuntu
sudo apt-get install calibre
# macOS
brew install --cask calibre
# Verify tools are in PATH
which calibredb
which ebook-convert
which ebook-meta
Usage
Basic Commands
# Show help
cli-anything-calibre --help
# Start interactive REPL mode
cli-anything-calibre
# Connect to a Calibre library
cli-anything-calibre library connect ~/Calibre\ Library
# Run with JSON output (for agent consumption)
cli-anything-calibre --json books list
REPL Mode
When invoked without a subcommand, the CLI enters an interactive REPL session:
cli-anything-calibre
# Enter commands interactively with tab-completion and history
# Use 'help' to see available commands
# Use 'quit' or 'exit' to leave

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-calibre is a skill published in the GitHub repository HKUDS/CLI-Anything (49,083 stars, last pushed 17d ago), licensed Apache-2.0. It adds 49 tokens to every session and 1,892 once invoked, about $0.0002 per session on Opus 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.
