What it does

Pp Woot is an agent skill from mvanhorn/printing-press-library. Printing Press CLI for Woot. Search live deals, sync them locally, and query the read-only browser GraphQL API.

Its SKILL.md is about 3.2k 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 GraphQL. It works with GraphQL. 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 GraphQL

Example prompts

  • “/pp-woot”

Requirements

  • Node.js
  • A credential in D24QG5ZSX8XDC4_CLOUDFRONT_API_KEY
  • 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: woot-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:

    • claude
    • npx
    • go

    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:

    • D24QG5ZSX8XDC4_CLOUDFRONT_API_KEY

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

Context cost

Pp Woot loads about 3.2k tokens when it runs. Until then it costs about 30 tokens; SKILL.md has 1,511 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~30
When it runs · the whole SKILL.md, loaded when a task matches
~3.2k

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.

Woot — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the woot-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 woot --cli-only
  2. Verify: woot-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 1.26.5 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/commerce/woot/cmd/woot-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.

Find offers that are buried deep in Woot's paginated All Deals catalog, then save a locally searchable snapshot with explicit completeness metadata. The CLI exposes the browser-observed searchOffers query without allowing GraphQL mutations.

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.

Unique Capabilities

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

Live deal discovery
  • deals — Scan Woot's paged All Deals results and filter live offers by keyword.

    Use this when Woot's visible All Deals pages contain an offer that a single GraphQL page or direct offer lookup would miss; scan metadata reports short windows, duplicate IDs, and rows without identities.

    bash
    woot-pp-cli deals rayon --limit 10000 --agent

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.

Discovery Signals

This CLI was generated with browser-observed traffic context.

  • Capture coverage: 7 API entries from 7 total network entries
  • Protocols: graphql (92% confidence)
  • Auth signals: api_key — headers: x-api-key
  • Candidate command ideas: list_graphql — Derived from observed GET /graphql traffic.

Recipes

Search a filtered slice of All Deals
bash
woot-pp-cli deals laptop --category computers --price-range 50-100 --limit 500 --agent

Scan current computer deals priced from $50 to $100 and return title matches as compact JSON.

Command Reference

deals — Search Woot All Deals offers

  • woot-pp-cli deals [keyword] — scan Woot's paged All Deals GraphQL results up to --limit, then filter titles, slugs, and item attributes locally.
  • woot-pp-cli deals [keyword] --from-url <woot-alldeals-url> — reuse category, price, and page filters from a copied Woot /alldeals URL.
  • woot-pp-cli deals [keyword] --category sport --price-range under-25 --price-range 25-50 --page 13 — reproduce visible All Deals filters from CLI flags.

Machine output reports scanned, unique_scanned, duplicate_rows, missing_id_rows, expected_scan, and incomplete. The completeness flag covers the requested live scan window; it does not claim that a smaller --limit covered Woot's entire catalog. Repeated IDs are omitted from results, and human table output warns when a requested window is incomplete.

graphql — Run read-only Woot GraphQL queries

  • woot-pp-cli graphql — fetch one current All Deals offer with a default searchOffers query.
  • woot-pp-cli graphql --query '<query>' — run a custom read-only Woot GraphQL query; mutation and subscription documents are rejected.

sync and search — Build and query an offline Woot deal index

  • woot-pp-cli sync --full — start at the head of All Deals, store normalized offers and prices, and prune expired rows only after two consecutive full scans return the same complete set of deal IDs. If Woot changes between scans, the CLI preserves existing rows and marks the snapshot incomplete for another pass.
  • woot-pp-cli search '<query>' --type deals --data-source local — search the local deal catalog without another Woot request.

Woot's mutable offset feed can repeat IDs or return fewer unique rows than TotalHits. Live scans expose this explicitly, and an incomplete sync warning is a deliberate non-success: local matches remain useful, but missing local matches are not authoritative until a later sync verifies the catalog.

--no-prune deliberately retains rows outside the verified live ID set. The store remains marked incomplete while those rows exist; use sync --full without --no-prune to publish an exact current local snapshot.

Finding the right command

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

bash
woot-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

Capture the x-api-key value from a successful graphql request made by your own Woot All Deals browser session, then provide it through D24QG5ZSX8XDC4_CLOUDFRONT_API_KEY or auth set-token.

Run woot-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
    woot-pp-cli graphql --agent --select data.searchOffers.TotalHits
  • 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": "local", "synced_at": "...", "reason": "...", "incomplete": true, "resume_cursor": "..."},
  "results": <data>
}

Parse .results for data and .meta.source to know whether it's live or local. When .meta.incomplete is true, run sync again before treating a missing local match as authoritative; .meta.resume_cursor records where that retry will begin. 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.

Paths and state

Agents should treat the CLI's path resolver as part of the runtime contract:

  • Use --home <dir> for one invocation, or set WOOT_HOME=<dir> to relocate all four path kinds under one root.

  • Use per-kind env vars only when a specific kind must diverge: WOOT_CONFIG_DIR, WOOT_DATA_DIR, WOOT_STATE_DIR, WOOT_CACHE_DIR.

  • Resolution order is per-kind env var, --home, WOOT_HOME, XDG (XDG_CONFIG_HOME, XDG_DATA_HOME, XDG_STATE_HOME, XDG_CACHE_HOME), then platform defaults.

  • config contains settings like config.toml and profiles. data contains credentials.toml, data.db, cookies, and auth sidecars. state contains persisted queries, jobs, and teach.log. cache contains regenerable HTTP/cache files.

  • Stored secrets live in credentials.toml under the data dir. Existing legacy config.toml secrets are read for compatibility and leave config.toml on the first auth write.

  • Run woot-pp-cli doctor --fail-on warn to surface path and credential-location warnings. agent-context exposes a schema v4 paths block for agents that need the resolved dirs.

  • For MCP, pass relocation through the MCP host config. The MCP binary does not inherit CLI flags:

    json
    {
      "mcpServers": {
        "woot": {
          "command": "woot-pp-mcp",
          "env": {
            "WOOT_HOME": "/srv/woot"
          }
        }
      }
    }

Fleet precedence: an inherited per-kind env var overrides an explicit --home for that kind. Use WOOT_HOME or per-kind vars as durable fleet levers, and use --home only for a single invocation. Relocation is not reversible by unsetting env vars; move files manually before clearing WOOT_HOME, or doctor will not find credentials left under the former root.

Agent Feedback

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

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

Entries are stored locally as feedback.jsonl under the resolved data dir. They are never POSTed unless WOOT_FEEDBACK_ENDPOINT is set AND either --send is passed or WOOT_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.

woot-pp-cli profile save briefing --json
woot-pp-cli --profile briefing graphql
woot-pp-cli profile list --json
woot-pp-cli profile show briefing
woot-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 woot-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

Install the MCP binary from this CLI's published public-library entry or pre-built release, then register it:

bash
claude mcp add woot-pp-mcp -- woot-pp-mcp

Verify: claude mcp list

Direct Use

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