Description

Mercury — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the mercury-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 mercury --cli-only

Verify: mercury-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/payments/mercury/cmd/mercury-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.

Unique Capabilities

These capabilities aren't available in any other tool for this API.

workflow payment-plan — Builds a read-only approval plan with body, idempotency key, dry-run command, and execute command before payment or transfer writes.

Agents can prepare exact write commands without moving money.
```
mercury-pp-cli workflow payment-plan --kind transfer --source-account-id acct_src --destination-account-id acct_dst --amount 25 --agent
```
workflow archive — Syncs supported Mercury resources into a local SQLite store for offline search and analytics.

Reduces API calls and gives agents repeatable context.
```
mercury-pp-cli workflow archive --agent
```
agent-context — Emits machine-readable command metadata for agents and MCP hosts.

Improves autonomous command selection and reduces context waste.
```
mercury-pp-cli agent-context --agent
```

Finding the right command

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

mercury-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

Store your access token:

mercury-pp-cli auth set-token YOUR_TOKEN_HERE

Or set MERCURY_BEARER_AUTH as an environment variable.

Run mercury-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:
```
mercury-pp-cli account mock-value --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
Explicit retries — use --idempotent only when an already-existing create should count as success, and --ignore-missing only when a missing delete target should count as success

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:

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

Entries are stored locally at ~/.mercury-pp-cli/feedback.jsonl. They are never POSTed unless MERCURY_FEEDBACK_ENDPOINT is set AND either --send is passed or MERCURY_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.

mercury-pp-cli profile save briefing --json
mercury-pp-cli --profile briefing account mock-value
mercury-pp-cli profile list --json
mercury-pp-cli profile show briefing
mercury-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 mercury-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/payments/mercury/cmd/mercury-pp-mcp@latest

claude mcp add mercury-pp-mcp -- mercury-pp-mcp

Verify: claude mcp list

Direct Use

Check if installed: which mercury-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:

mercury-pp-cli <command> [subcommand] [args] --agent

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