Recipe Goat — Printing Press CLI

Prerequisites: Install the CLI

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

Install via the Printing Press installer:
npx -y @mvanhorn/printing-press install recipe-goat --cli-only

Verify: recipe-goat-pp-cli --version

Ensure $GOPATH/bin (or $HOME/go/bin) is on $PATH.

If the npx install fails (no Node, offline, etc.), fall back to a direct Go install (requires Go 1.26.3 or newer):
go install github.com/mvanhorn/printing-press-library/library/food-and-dining/recipe-goat/cmd/recipe-goat-pp-cli@latest

If --version reports "command not found" after install, the install step did not put the binary on $PATH. Do not proceed with skill commands until verification succeeds.

When Not to Use This CLI

Do not activate this CLI for requests that require creating, updating, deleting, publishing, commenting, upvoting, inviting, ordering, sending messages, booking, purchasing, or changing remote state. This printed CLI exposes read-only commands for inspection, export, sync, and analysis.

HTTP Transport

This CLI uses Chrome-compatible HTTP transport for browser-facing endpoints. It does not require a resident browser process for normal API calls.

Command Reference

foods — USDA FoodData Central — ingredient nutrition lookups

recipe-goat-pp-cli foods get — Get a specific food by FDC ID

recipe-goat-pp-cli foods list — List foods paginated

recipe-goat-pp-cli foods search — Search USDA FoodData Central for foods matching a query

Finding the right command

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

recipe-goat-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

Set your API key via environment variable:

export USDA_FDC_API_KEY="<your-key>"

Or persist it in ~/.config/recipe-goat-pp-cli/config.toml.

Run recipe-goat-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:

recipe-goat-pp-cli foods 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

Read-only — do not use this CLI for create, update, delete, publish, comment, upvote, invite, order, send, or other mutating requests

Response envelope

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

{
  "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:

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

Entries are stored locally at ~/.recipe-goat-pp-cli/feedback.jsonl. They are never POSTed unless RECIPE_GOAT_FEEDBACK_ENDPOINT is set AND either --send is passed or RECIPE_GOAT_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:

Sink
Effect

stdout
Default; 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.

recipe-goat-pp-cli profile save briefing --json
recipe-goat-pp-cli --profile briefing foods list
recipe-goat-pp-cli profile list --json
recipe-goat-pp-cli profile show briefing
recipe-goat-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

Code
Meaning

0
Success

2
Usage error (wrong arguments)

3
Resource not found

4
Authentication required

5
API error (upstream issue)

7
Rate limited (wait and retry)

10
Config error

Argument Parsing

Parse $ARGUMENTS:

Empty, help, or --help → show recipe-goat-pp-cli --help output

Starts with install → ends with mcp → MCP installation; otherwise → see Prerequisites above

Anything else → Direct Use (execute as CLI command with --agent)

MCP Server Installation

Install the MCP server:
go install github.com/mvanhorn/printing-press-library/library/other/recipe-goat-pp-cli/cmd/recipe-goat-pp-mcp@latest

Register with Claude Code:
claude mcp add recipe-goat-pp-mcp -- recipe-goat-pp-mcp

Verify: claude mcp list

Direct Use

Check if installed: which recipe-goat-pp-cli
If not found, offer to install (see Prerequisites at the top of this skill).

Match the user query to the best command from the Unique Capabilities and Command Reference above.

Execute with the --agent flag:
recipe-goat-pp-cli <command> [subcommand] [args] --agent

If ambiguous, drill into subcommand help: recipe-goat-pp-cli <command> --help.
