What it does

Pp Google Photos is an agent skill from mvanhorn/printing-press-library. Printing Press CLI for Google Photos. Google Photos Library and Picker APIs for app-created media, albums, uploads, and user-selected media.

Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

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.

Example prompts

  • “/pp-google-photos”

Requirements

  • Node.js
  • Pre-approved tools (allowed-tools): Read, Bash

Workflow steps

3 steps, taken from the first numbered list in SKILL.md.

  1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and…
  2. Verify: google-photos-pp-cli --version
  3. Ensure the reported install directory is on $PATH for the agent/runtime that will invoke this skill.

What it can do on your machine

Read from SKILL.md and the folder at commit d9a1696. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Bash

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Shell commands in SKILL.md call:

    • make
    • go
    • claude
    • npx

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    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.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Pp Google Photos loads about 2.8k tokens when it runs. Until then it costs about 39 tokens; SKILL.md has 1,093 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~39
When it runs · the whole SKILL.md, loaded when a task matches
~2.8k

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.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

    allowed-tools: Read, Bash

Automated 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.

Google Photos — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the google-photos-pp-cli binary. You must verify the CLI is installed before invoking any command from this skill. If it is missing, install it first:

  1. Install via the Printing Press installer. It defaults binaries to $HOME/.local/bin on macOS/Linux and %LOCALAPPDATA%\Programs\PrintingPress\bin on Windows:
    bash
    npx -y @mvanhorn/printing-press-library install google-photos --cli-only
  2. Verify: google-photos-pp-cli --version
  3. Ensure the reported install directory is on $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):

bash
go install github.com/mvanhorn/printing-press-library/library/media-and-entertainment/google-photos/cmd/google-photos-pp-cli@latest

If --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.

Hand-written commands

  • google-photos-pp-cli upload file <path> — Upload raw photo or video bytes and print the upload token for media-items batch-create.
  • google-photos-pp-cli picker wait <session-id> — Poll a Picker session until selected media items are ready.
  • google-photos-pp-cli schema --pretty — Emit machine-readable command, flag, auth, and safety-policy metadata.
  • google-photos-pp-cli auth list — List stored OAuth accounts.
  • google-photos-pp-cli auth use <account-email> — Set the default OAuth account.
  • google-photos-pp-cli auth remove <account-email> — Remove a stored OAuth account.

Google Photos Scope Limits

Google Photos Library API read and edit scopes are limited to app-created albums and media. Use Library API commands here for app-created content, uploads, and album/media management. Use Picker commands when a user needs to select media from their broader Google Photos library.

Finding the right command

When you know what you want to do but not which command does it, ask the CLI directly:

bash
google-photos-pp-cli which "<capability in your own words>"

which resolves a natural-language capability query to the best matching command from this CLI's curated feature index. Exit code 0 means at least one match; exit code 2 means no confident match — fall back to --help or use a narrower query.

Auth Setup

Authenticate via the browser:

bash
google-photos-pp-cli auth login --client-id "$GOOGLE_PHOTOS_CLIENT_ID"

Tokens are stored locally and refreshed automatically.

For multiple Google accounts, store tokens under account emails and select the account explicitly:

bash
google-photos-pp-cli auth login you@example.com --client-id "$GOOGLE_PHOTOS_CLIENT_ID"
google-photos-pp-cli auth list --json
google-photos-pp-cli auth use you@example.com
google-photos-pp-cli --account you@example.com albums list --agent

Account selection order: --account, GOOGLE_PHOTOS_ACCOUNT, auth use default, then legacy single-token config.

Run google-photos-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color --yes.

  • Pipeable — JSON on stdout, errors on stderr

  • Filterable — --select keeps a subset of fields. Dotted paths descend into nested structures; arrays traverse element-wise. Critical for keeping context small on verbose APIs:

    bash
    google-photos-pp-cli albums list --agent --select id,name,status

  • Previewable — --dry-run shows the request without sending

  • Offline-friendly — sync/search commands can use the local SQLite store when available

  • Non-interactive — never prompts, every input is a flag

  • Guarded — use --enable-commands / --disable-commands with dotted command paths:

    bash
    google-photos-pp-cli --enable-commands albums.list albums list --agent
google-photos-pp-cli --disable-commands picker.delete-session picker delete-session SESSION_ID --agent

  • Introspectable — use schema --pretty or agent-context --pretty for the full JSON command contract.

Baked Safety Profiles

Build stronger local guardrails when exposing this CLI or MCP server to autonomous agents:

bash
make build-readonly
make build-agent-safe
make build-mcp-readonly
make build-mcp-agent-safe

safety_readonly permits read/list/search/export/schema-style commands and blocks Google Photos mutations. safety_agent_safe permits reads and local archive/search workflows while blocking auth writes, uploads, creates, patches, deletes, and album/media mutations.

Response envelope

Commands that read from the local store or the API wrap output in a provenance envelope:

json
{
  "meta": {"source": "live" | "local", "synced_at": "...", "reason": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. A human-readable N results (live) summary is printed to stderr only when stdout is a terminal — piped/agent consumers get pure JSON on stdout.

Agent Feedback

When you (or the agent) notice something off about this CLI, record it:

google-photos-pp-cli feedback "the --since flag is inclusive but docs say exclusive"
google-photos-pp-cli feedback --stdin < notes.txt
google-photos-pp-cli feedback list --json --limit 10

Entries are stored locally at ~/.google-photos-pp-cli/feedback.jsonl. They are never POSTed unless GOOGLE_PHOTOS_FEEDBACK_ENDPOINT is set AND either --send is passed or GOOGLE_PHOTOS_FEEDBACK_AUTO_SEND=true. Default behavior is local-only.

Write what surprised you, not a bug report. Short, specific, one line: that is the part that compounds.

Output Delivery

Every command accepts --deliver <sink>. The output goes to the named sink in addition to (or instead of) stdout, so agents can route command results without hand-piping. Three sinks are supported:

SinkEffect
stdoutDefault; write to stdout only
file:<path>Atomically write output to <path> (tmp + rename)
webhook:<url>POST the output body to the URL (application/json or application/x-ndjson when --compact)

Unknown schemes are refused with a structured error naming the supported set. Webhook failures return non-zero and log the URL + HTTP status on stderr.

Named Profiles

A profile is a saved set of flag values, reused across invocations. Use it when a scheduled agent calls the same command every run with the same configuration - HeyGen's "Beacon" pattern.

google-photos-pp-cli profile save briefing --json
google-photos-pp-cli --profile briefing albums list
google-photos-pp-cli profile list --json
google-photos-pp-cli profile show briefing
google-photos-pp-cli profile delete briefing --yes

Explicit flags always win over profile values; profile values win over defaults. agent-context lists all available profiles under available_profiles so introspecting agents discover them at runtime.

Exit Codes

CodeMeaning
0Success
2Usage error (wrong arguments)
3Resource not found
4Authentication required
5API error (upstream issue)
7Rate limited (wait and retry)
10Config error

Argument Parsing

Parse $ARGUMENTS:

  1. Empty, help, or --help → show google-photos-pp-cli --help output
  2. Starts with install → ends with mcp → MCP installation; otherwise → see Prerequisites above
  3. Anything else → Direct Use (execute as CLI command with --agent)

MCP Server Installation

  1. Install the MCP server:
    bash
    go install github.com/mvanhorn/printing-press-library/library/media-and-entertainment/google-photos/cmd/google-photos-pp-mcp@latest
  2. Register with Claude Code:
    bash
    claude mcp add google-photos-pp-mcp -- google-photos-pp-mcp
  3. Verify: claude mcp list

Direct Use

  1. Check if installed: which google-photos-pp-cli If not found, offer to install (see Prerequisites at the top of this skill).
  2. Match the user query to the best command from the Unique Capabilities and Command Reference above.
  3. Execute with the --agent flag:
    bash
    google-photos-pp-cli <command> [subcommand] [args] --agent
  4. If ambiguous, drill into subcommand help: google-photos-pp-cli <command> --help.
