Shopper — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the shopper-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:

   npx -y @mvanhorn/printing-press-library install shopper --cli-only

2. Verify: shopper-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). This installs into $GOPATH/bin (default $HOME/go/bin), so add that directory to $PATH instead:

go install github.com/mvanhorn/printing-press-library/library/commerce/shopper/cmd/shopper-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.

shopper-pp-cli covers all six Shopper storefronts (Compra Programada, Fresh, Pet, Compra Única, Now, Now Bebidas) with correct store/cluster scoping, full siteapi REST surface, browser-deep-link helpers for subscription mutations, and a local SQLite layer for offline product search, basket diffs, price tracking, and cross-store spend rollup.

When to Use This CLI

Use shopper-pp-cli when automating Shopper basket management, monitoring charge schedules, analyzing spend patterns across storefronts, or building agent workflows around the Shopper subscription cycle. Ideal for recurring-basket optimization, pre-cycle audit, and delivery-schedule awareness.

Anti-triggers

Do not use this CLI for:

• Do not use for placing orders or confirming checkout — use checkout open to hand off to the browser
• Do not use for adding or removing saved credit cards — card management requires browser session
• Do not use for ultra-fast delivery slot selection on now/now-bebidas — delivery slots for these stores require the browser checkout flow
• Do not use for cancelling orders — cancellation is not available via siteapi REST

Unique Capabilities

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

Subscription intelligence

• charge-calendar — Every upcoming cycle's charge date, edit-lock deadline, and delivery date in one timeline so you never miss an edit window or get surprised by a charge.

  Use when an agent needs to know whether the edit window is still open before modifying a recurring basket.

  shopper-pp-cli charge-calendar --store programada --agent

• basket diff — Compares your current recurring basket against a previous cycle's snapshot to show exactly what was added, dropped, or re-quantified before the template locks.

  Use when an agent needs to verify what changed in the basket since the last confirmed delivery cycle.

  shopper-pp-cli basket diff --store programada --agent

• cashback optimize — Computes the cheapest set of items to add (or whether to wait) to cross the next cashback tier, favoring things you'll need anyway.

  Use when an agent is finalising a basket and wants to maximise cashback return before the edit window closes.

  shopper-pp-cli cashback optimize --tier 2399 --store programada --agent

Basket contents

• cart list-items — Lists what is actually in the basket: product, department, quantity, unit price and line total, with paused lines reported separately.

  Reads GET /cart/list, the endpoint behind the web basket page. cart list-summary reads GET /cart/summary, which returns totals only and carries no item array — so it can tell you the basket costs R$ 27,96 but never what made it up. basket diff, price-watch --only-basket and any agent reasoning about basket contents read through this command.

  shopper-pp-cli cart list-items --store programada --agent

Local state that compounds

• price-watch — Tracks the price history of the SKUs you actually buy and alerts when one rises or drops meaningfully versus your own purchase baseline.

  Use when an agent needs to know if a subscribed product has changed price significantly since the last order.

  shopper-pp-cli price-watch --store programada --agent

• restock predict — Predicts when you'll run out of each staple from your historical buying cadence and suggests what to add to the upcoming basket.

  Use when an agent needs to pre-populate a recurring basket with items likely running low before the next cycle.

  shopper-pp-cli restock predict --store programada --agent

• catalog drift — Flags products you buy that were discontinued, silently swapped, or kept their price while shrinking the pack, surfacing the real R$/kg or R$/L change.

  Use when an agent needs to audit whether the recurring basket still contains the same products as originally added.

  shopper-pp-cli catalog drift --store programada --agent

Customer journey plumbing

• checkout preview — Aggregates cart totals, next delivery date, charge date, minimum-order status, and accepted payment types into one pre-checkout view before you open the browser.

  Use when an agent needs to confirm basket readiness and charge schedule before directing the user to open the browser for final payment.

  shopper-pp-cli checkout preview --store programada --agent

Freshness Contract

This printed CLI owns bounded freshness only for registered store-backed read command paths. In --data-source auto mode, those paths check sync_state and may run a bounded refresh before reading local data. --data-source local never refreshes. --data-source live reads the API and does not mutate the local store. Set SHOPPER_NO_AUTO_REFRESH=1 to skip the freshness hook without changing source selection.

Covered paths:

• shopper-pp-cli address
• shopper-pp-cli address get

When JSON output uses the generated provenance envelope, freshness metadata appears at meta.freshness. Treat it as current-cache freshness for the covered command path, not a guarantee of complete historical backfill or API-specific enrichment.

Finding the right command

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

shopper-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.

Hand-written Extensions

These commands are declared by the spec author and require separate hand-written wiring; the generator does not emit Cobra registration for them. They are listed here for discoverability and are intentionally outside ## Command Reference so the verify-skill unknown-command check does not treat them as generator-owned paths.

• shopper-pp-cli stores — List all available Shopper storefronts with IDs, cluster IDs, payment parameters, and capability flags
• shopper-pp-cli checkout preview — Pre-checkout summary: basket totals, delivery date, charge date, min-order status, and accepted payment types (read-only
• shopper-pp-cli checkout open — Open the Shopper checkout page in the system browser (subscription-based payment via session login)
• shopper-pp-cli delivery reschedule [--store <store>] — Open the delivery reschedule calendar in the browser (POST /shop/minha-conta/alterar-data requires session cookie)
• shopper-pp-cli delivery skip — Open the skip-delivery page in the browser — subscription stores only (POST /shop/minha-conta/pular-entrega/ requires
• shopper-pp-cli delivery suspend — Open the suspend-subscription page in the browser (POST /shop/minha-conta/suspender-entrega requires session cookie)
• shopper-pp-cli delivery boleto — Open the boleto-retrieval page in the browser to get the bank slip for the current order
• shopper-pp-cli subscription pause — Open the subscription-pause page in the browser (POST /shop/carrinho/pause/ requires session cookie)
• shopper-pp-cli subscription resume — Open the subscription-resume page in the browser (POST /shop/carrinho/play/ requires session cookie)
• shopper-pp-cli payment cards — Show saved payment card count and open card-management in the browser (card add/delete is browser-required

Recipes

See what is actually in the basket

cart list-summary answers "how much", cart list-items answers "what". Line totals are sorted biggest-first, and paused products are listed apart so they never inflate the active count.

shopper-pp-cli cart list-items --store programada --agent

Remove several units of one product

POST /cart/remove decrements a line by exactly one unit per call and ignores the quantity it is given, so the CLI issues one call per unit and stops early once the line is empty.

# Take 3 units of product 36756 off the Compra Unica basket.
shopper-pp-cli cart remove --id 36756 --quantity 3 --store unica --agent

# Confirm the line is gone.
shopper-pp-cli cart list-items --store unica --agent

Confirm the CLI store table still matches the API

cluster_id is an independent dimension, not a copy of the store id — five of the six storefronts share cluster 1 and only the ultra-fast pair sits on cluster 11. stores compares the CLI's baked table against the live payload and prints a store table drift warning on stderr if they disagree.

shopper-pp-cli stores --agent 2>drift.txt; cat drift.txt

Check if the edit window is still open

shopper-pp-cli charge-calendar --store programada --agent --select next_delivery_date,edit_lock_date,charge_date

Returns the key dates for the next cycle; compare edit_lock_date to today to know if the basket can still be changed.

Find items to add for next cashback tier

shopper-pp-cli cashback optimize --store programada --agent

Computes the cheapest catalog additions to cross the next cashback threshold using your live cart and synced product data.

Cross-store spend rollup for last 12 months

shopper-pp-cli orders spend --agent --select store,month,total

Queries all 6 storefronts and returns a month-by-store spend matrix for budgeting analysis.

Detect if a subscribed product changed price

shopper-pp-cli price-watch --store programada --agent --select product_id,name,price_now,price_baseline,change_pct

Scans synced price history for products in your basket and flags meaningful price movements.

Pre-checkout summary with charge date

shopper-pp-cli checkout preview --store programada --agent --select total_amount,delivery_date,charge_date,min_order_met,payment_methods

Aggregates cart/delivery/payment data so an agent can confirm basket readiness before directing the user to open the checkout browser.

Auth Setup

Set SHOPPER_TOKEN to your Shopper JWT (from the siteapi Authorization header in browser DevTools). Run 'shopper-pp-cli doctor' to verify. The token is long-lived for the subscription cycle. Never store raw card numbers or CPF in config; card management always opens the browser.

Run shopper-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:

  shopper-pp-cli address --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

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 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 SHOPPER_HOME=<dir> to relocate all four path kinds under one root.

• Use per-kind env vars only when a specific kind must diverge: SHOPPER_CONFIG_DIR, SHOPPER_DATA_DIR, SHOPPER_STATE_DIR, SHOPPER_CACHE_DIR.

• Resolution order is per-kind env var, --home, SHOPPER_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 shopper-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:

  {
    "mcpServers": {
      "shopper": {
        "command": "shopper-pp-mcp",
        "env": {
          "SHOPPER_HOME": "/srv/shopper"
        }
      }
    }
  }

Fleet precedence: an inherited per-kind env var overrides an explicit --home for that kind. Use SHOPPER_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 SHOPPER_HOME, or doctor will not find credentials left under the former root.

Automatic learning

This CLI ships a self-capturing learning loop. The CLI does its own bookkeeping: every invocation is journaled locally, a failed flag followed by a corrected retry auto-derives a flag_alias candidate, and a teach on a query family without a playbook auto-synthesizes a playbook_candidate from the session's journal. Your job is judgment only: recall first, act on surfaced candidates, teach the final answer, playbook amend when you observe a correction. You never record failures by hand.
