What it does

Pp Sprocket is an agent skill from mvanhorn/printing-press-library. Your youth-soccer club's schedule, teams, and dues from the terminal — with merged multi-kid agendas, conflict detection Trigger phrases: when is my kid's next game, this week's soccer schedule, do we have any schedule conflicts, away games this month, what do we owe the soccer club, use sprocket, run sprocket.

Its SKILL.md is about 3.7k 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.

When your agent uses it

  • Phrases: when is my kids next game
  • This weeks soccer schedule
  • Do we have any schedule conflicts
  • Away games this month

Example prompts

  • “s next game, this week”
  • “/pp-sprocket”

Requirements

  • Node.js
  • A credential in SPROCKET_TOKEN
  • 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: sprocket-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 76de244. 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:

    • 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 these keys or tokens, usually read from environment variables:

    • SPROCKET_TOKEN

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

Context cost

Pp Sprocket loads about 3.7k tokens when it runs. Until then it costs about 85 tokens; SKILL.md has 1,650 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~85
When it runs · the whole SKILL.md, loaded when a task matches
~3.7k

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.

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.

Sprocket Sports — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the sprocket-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 sprocket --cli-only
  2. Verify: sprocket-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 1.26.4 or newer). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:

bash
go install github.com/mvanhorn/printing-press-library/library/productivity/sprocket/cmd/sprocket-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.

Sprocket Sports CLI wraps your club's Sprocket dashboard API so you can answer the questions a parent actually asks: 'when is the next game' (next), 'what's on this week' (week), 'plan the next two weeks for both kids' (agenda), 'any double-bookings' (conflicts), and 'what do we owe' (owed). It merges every one of your players' teams into a single view the per-team web dashboard can't produce, and exports everything to your phone calendar with ical.

When to Use This CLI

Use this CLI when an agent or script needs a Sprocket Sports club's schedule, rosters, programs, registrations, or dues — especially merged across multiple children and teams, or as date-math (next game, this week, conflicts, away games) that the per-team web dashboard cannot answer in one view. It is ideal for reminders, carpool and away-game planning, iCal subscriptions, and 'what do we owe' roll-ups.

Anti-triggers

Do not use this CLI for:

  • Do not use this CLI for league scores or standings — the parent dashboard API does not expose them (they are league-admin level).
  • Do not use it for coach or club announcements and messaging — that surface is not available here.
  • Do not use it to register, pay, RSVP, or otherwise change anything — v1 is strictly read-only.
  • Works for any Sprocket club, but only one at a time: it targets whatever SPROCKET_CLUB / SPROCKET_BASE_URL (or config base_url) is set to, defaulting to jfcsoccer. The token must match that club. Don't expect cross-club queries in a single invocation.

Unique Capabilities

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

Schedule, the way a parent asks
  • week — Every game and practice for the current week across all your players' teams, in one view.

    Reach for this when asked 'what's on this week' for a family with kids on different teams.

    bash
    sprocket week
  • next — The single next upcoming game or practice across all your players' teams: what, when, where, home/away, opponent.

    Reach for this for 'when is my kid's next game' or a one-line reminder.

    bash
    sprocket next --agent --select clubCalendarEvent.title,clubCalendarEvent.startDate,clubCalendarEvent.opponent,clubCalendarEvent.awayGame
  • agenda — Both kids' separate team schedules merged into one chronological agenda over an N-day window.

    Reach for this to plan the family's next two weeks in a single sorted list.

    bash
    sprocket agenda --days 14
  • conflicts — Flags time overlaps and impossible tight time-plus-location gaps between events across all your players.

    Reach for this to catch a double-booked Saturday before Saturday morning.

    bash
    sprocket conflicts --days 14
  • away — Away games only, location-first, with field, opponent, and date — built for the carpool group chat.

    Reach for this when planning away-game driving or posting a travel list.

    bash
    sprocket away --weeks 4
  • ical — Emit the merged schedule as an RFC-5545 .ics file for phone-calendar subscription.

    Reach for this to get soccer events into Apple/Google Calendar.

    bash
    sprocket ical --days 60
  • since — What schedule items were added, moved, or cancelled since the last time you ran it.

    Reach for this to catch a moved practice or a newly-added game.

    bash
    sprocket since
Money and deadlines
  • owed — Total money owed across all your players: registration balances plus overdue invoices, with one number.

    Reach for this for 'what do we still owe the club' across multiple kids.

    bash
    sprocket owed
  • deadlines — Open registration programs sorted by how soon they close, flagging ones closing within N days.

    Reach for this to avoid missing a registration window.

    bash
    sprocket deadlines --days 14

Finding the right command

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

bash
sprocket-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.

Recipes

Next game as a one-line reminder
bash
sprocket next --agent --select clubCalendarEvent.title,clubCalendarEvent.startDate,clubCalendarEvent.opponent,clubCalendarEvent.awayGame

Narrow the deeply-nested event to just the fields a reminder needs; pipe to a text/cron job.

Subscribe in your phone calendar
bash

Write 60 days of merged events to an .ics file you can import or host for subscription.

Auth Setup

Sprocket Sports uses OAuth2/OIDC (Duende IdentityServer at login.sprocketsports.com) and the API takes a Bearer access token. This CLI authenticates with that token: set SPROCKET_TOKEN to the access_token from your logged-in dashboard session. To find it: open your club dashboard in Chrome, open DevTools, go to Application > Session Storage, find the 'oidc.user:...sprocket-sports' entry, and copy its access_token value. Tokens are short-lived (about an hour), so re-copy when commands start returning 401.

Any Sprocket club, not just one. The CLI defaults to the jfcsoccer tenant but works for any https://<club>.sprocketsports.com. Point it at yours with export SPROCKET_CLUB=<subdomain> (shorthand) or export SPROCKET_BASE_URL=https://<club>.sprocketsports.com, or set base_url in ~/.config/sprocket-pp-cli/config.toml. The token must come from that same club's session (tokens are club-scoped).

Run sprocket-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
    sprocket-pp-cli family --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:

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 AND no machine-format flag (--json, --csv, --compact, --quiet, --plain, --select) is set — piped/agent consumers and explicit-format runs get pure JSON on stdout.

Agent Feedback

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

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

Entries are stored locally at ~/.local/share/sprocket-pp-cli/feedback.jsonl. They are never POSTed unless SPROCKET_FEEDBACK_ENDPOINT is set AND either --send is passed or SPROCKET_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.

sprocket-pp-cli profile save briefing --json
sprocket-pp-cli --profile briefing family
sprocket-pp-cli profile list --json
sprocket-pp-cli profile show briefing
sprocket-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 sprocket-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/productivity/sprocket/cmd/sprocket-pp-mcp@latest
  2. Register with Claude Code:
    bash
    claude mcp add sprocket-pp-mcp -- sprocket-pp-mcp
  3. Verify: claude mcp list

Direct Use

  1. Check if installed: which sprocket-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
    sprocket-pp-cli <command> [subcommand] [args] --agent
  4. If ambiguous, drill into subcommand help: sprocket-pp-cli <command> --help.
