icloud-pp-cliQuery your Apple iCloud data from the command line — Photos library storage analysis, iMessage history search and export, largest-file finder, and delete via AppleScript.
Icloud Pp CLI is an agent skill from mvanhorn/printing-press-library. Query your Apple iCloud data from the command line — Photos library storage analysis, iMessage history search and export, largest-file finder, and delete via AppleScript. macOS only. No network calls or iCloud API token required.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Productivity & Automation, covering Messaging and chat bots. It works with macOS. The repository describes itself as: Official library of CLIs generated by the CLI Printing Press. Endorsed, tested, and community-contributed. The licence is Apache-2.0.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 0fdcc7a. It shows what the files ask for, not the result of running them.
Pre-approves these tools, so the agent can use them without asking each time:
ReadBashFrom allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
jqnpxgoFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md. Its commands use npx, which can reach the network depending on how they are called.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Icloud Pp CLI loads about 1.9k tokens when it runs. Until then it costs about 61 tokens; SKILL.md has 542 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check noted patterns worth knowing about, such as sudo or a known installer.
allowed-tools: Read, BashAutomated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

This skill drives the icloud-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:
$HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:npx -y @mvanhorn/printing-press-library install icloud --cli-onlyicloud-pp-cli --version$PATH for the agent/runtime that will invoke this skill.If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.6 or newer):
go install github.com/mvanhorn/printing-press-library/library/media-and-entertainment/icloud/cmd/icloud-pp-cli@latestIf --version reports "command not found" after install, the runtime cannot see the binary directory on $PATH. Do not proceed with skill commands until verification succeeds.
Always run doctor first to confirm your setup:
icloud-pp-cli doctorVerifies: macOS, Photos.app installed, library path found, database schema valid, asset count queryable, chat.db readable (Full Disk Access).
If your Photos library is in a non-default location:
icloud-pp-cli doctor --library "/Volumes/External/Photos Library.photoslibrary/database/Photos.sqlite"messages subcommands read ~/Library/Messages/chat.db directly, which on
macOS requires Full Disk Access (FDA) for the terminal app invoking the binary.
If a messages command fails with "Full Disk Access not granted", open System
Settings > Privacy & Security > Full Disk Access, add your terminal, quit and
reopen the terminal, and rerun. doctor reports FDA state automatically.

Query your Apple iCloud data from the command line — Photos library storage analysis, iMessage history search and export, largest-file finder, and delete via AppleScript. Icloud Pp CLI is an agent skill from mvanhorn/printing-press-library. Query your Apple iCloud data from the command line — Photos library storage analysis, iMessage history search and export, largest-file finder, and delete via AppleScript.
Icloud Pp CLI fits situations like: tasks that involve Messaging and chat bots.
Run `npx skills add mvanhorn/printing-press-library --skill icloud-pp-cli -a claude-code`. Or copy the skill folder (cli-skills/pp-icloud in mvanhorn/printing-press-library) into .claude/skills/icloud-pp-cli in your project. Claude Code loads it when a task matches its description.
Run `npx skills add mvanhorn/printing-press-library --skill icloud-pp-cli -a codex`. Or copy the skill folder (cli-skills/pp-icloud in mvanhorn/printing-press-library) into .agents/skills/icloud-pp-cli in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mvanhorn/printing-press-library --skill icloud-pp-cli -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/icloud-pp-cli, .gemini/skills/icloud-pp-cli, .github/skills/icloud-pp-cli and .opencode/skills/icloud-pp-cli in your project.
Going by SKILL.md and its folder, Icloud Pp CLI needs the command-line tools its instructions call (jq, npx and go). Our summary lists: Node.js. Its frontmatter pre-approves these tools: Read, Bash.
SKILL.md contains no URLs. Its commands use npx, which can reach the network depending on how they are called. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. Review the folder before installing.
Icloud Pp CLI is published under the Apache-2.0 licence (declared in SKILL.md). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.9k tokens (SKILL.md is roughly 7.4k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
