What it does

Pp Tidycal is an agent skill from mvanhorn/printing-press-library. Printing Press CLI for Tidycal. TidyCal's REST API provides a handful of endpoints which can be used to get information about your account and bookings.

Its SKILL.md is about 2.4k 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 Backend & APIs, covering REST APIs. 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

  • Tasks that involve REST APIs

Example prompts

  • “/pp-tidycal”

Requirements

  • Node.js
  • A credential in TIDYCAL_API_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: tidycal-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:

    • 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:

    • TIDYCAL_API_TOKEN

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

Context cost

Pp Tidycal loads about 2.4k tokens when it runs. Until then it costs about 41 tokens; SKILL.md has 974 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~41
When it runs · the whole SKILL.md, loaded when a task matches
~2.4k

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.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    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.

Tidycal — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the tidycal-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 tidycal --cli-only
  2. Verify: tidycal-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/productivity/tidycal/cmd/tidycal-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.

Unique Capabilities

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

Agentic scheduling
  • brief — Produce a contact-aware schedule brief for a day or date range.

    Use this before drafting prep notes or deciding whether a booking needs attention.

    bash
    tidycal-pp-cli brief --date today --format json
  • triage — Identify booking problems such as missing meeting URLs, duplicate contacts, off-hours bookings, cancelled bookings, and incomplete contact data.

    Use this to decide which bookings require operator review.

    bash
    tidycal-pp-cli triage --from today --to +7d --format json
  • propose-times — Fetch available TidyCal timeslots for a booking type and rank a paste-ready shortlist by date window, timezone, preference, and weekend policy.

    Use this when proposing meeting options in chat or email.

    bash
    tidycal-pp-cli propose-times 123 --from today --to +14d --count 3 --format json
  • followups — Create an AI-ready follow-up queue from recent bookings without sending messages or notifications.

    Use this to prepare follow-up tasks after recent meetings.

    bash
    tidycal-pp-cli followups --from -7d --to today --format json
  • assisted-book — Book on behalf of a contact through an inspectable dry-run and explicit confirmation gate.

    Use this only when the operator has approved the booking details.

    bash
    tidycal-pp-cli assisted-book 123 --name Ada --email ada@example.com --slot 2026-06-02T15:00:00Z --dry-run --format json

teams — Manage teams

  • tidycal-pp-cli teams get — Get details of a specific team.
  • tidycal-pp-cli teams list — Get a list of teams the authenticated user has access to.
Finding the right command

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

bash
tidycal-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

Run tidycal-pp-cli auth setup for the URL and steps to obtain a token (add --launch to open the URL). Then store it:

bash
tidycal-pp-cli auth set-token YOUR_TOKEN_HERE

Or set TIDYCAL_API_TOKEN as an environment variable.

Run tidycal-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
    tidycal-pp-cli booking-types 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

  • 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:

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:

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

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

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

Direct Use

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