Woolworths — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the woolworths-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 woolworths --cli-only

2. Verify: woolworths-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/woolworths/cmd/woolworths-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.

Woolworths shows you today's price and a SAVE badge, and the badge is exactly what shoppers say they cannot trust. This CLI keeps its own price history in SQLite, so real-special returns a verdict instead of a number, cycle forecasts when the next half-price window opens, and swap ranks alternatives by unit price normalised across measure bases. It needs no API key, no login for the catalogue, and no headless browser. It is read-only apart from adding to a guest trolley.

When to Use This CLI

Use this CLI for Australian grocery pricing questions that need a decided answer rather than raw product JSON: whether a special is genuine, when a discount is likely to return, which alternative is cheaper per unit, and what a whole shopping list costs versus last time. It is also the right tool for building or costing a trolley programmatically, since the guest trolley works without any account.

Anti-triggers

Do not use this CLI for:

• Do not use this CLI for Everyday Rewards points, boosters, or e-receipts - that stack is MFA-gated with short-lived tokens and is not automatable.
• Do not use this CLI to compare against Coles, ALDI or IGA - it covers Woolworths only.
• Do not use this CLI to look up a product by barcode - the barcode endpoint lives on a mobile API whose key is revoked.
• Do not use this CLI to place or pay for an order - it can build a trolley but does not check out.
• Do not use this CLI as a bulk catalogue scraper - it rate-limits deliberately, and walking every category is what gets shoppers IP-banned.
• Do not rely on 'sync' to build price history - on this API only 'settings' syncs blind; the history-recording commands are 'real-special' and 'specials-diff --refresh'.
• Do not use 'auth login --chrome' on Windows - browser-session import is unavailable there, so saved lists and past shops are unreachable on that platform.
• Do not use 'basket --dry-run' to price a list; it only echoes the action. Use '--record=false' for a real run that writes nothing.

Unique Capabilities

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

Local history that compounds

• real-special — Tells you whether an advertised special is genuinely cheap or just a lower number next to an inflated was-price.

  Reach for this instead of reading the SAVE badge: it returns one decided verdict per product rather than raw prices you have to judge yourself.

  woolworths-pp-cli real-special "tim tam" --limit 2 --agent

• cycle — Estimates when a product's next half-price window is likely to open, from its own recorded discount episodes.

  Use this to decide buy-one-or-buy-six on a stockpile item, instead of guessing whether the deal returns next month.

  woolworths-pp-cli cycle 6073909 --agent

• specials-diff — Shows what entered and left each specials group since your last sync, with how long since each entrant was last discounted.

  Reach for this on catalogue-rollover day to see only what actually changed rather than re-reading the whole specials list.

  woolworths-pp-cli specials-diff --limit 5 --agent

Unit-price intelligence

• swap — Ranks in-stock alternatives by unit price normalised across different measure bases, so per-100g and per-1kg tiles compare correctly.

  Pick this when the question is which product is genuinely cheaper per unit, not which has the lowest shelf price.

  woolworths-pp-cli swap "olive oil" --limit 3 --max-scan-pages 1 --agent

• multibuy — Works out what a multi-buy offer actually costs per unit at the quantity it demands, versus buying singly or buying a larger pack.

  Use this before accepting a 2-for-$9 style offer, since a bigger single pack is often cheaper per unit.

  woolworths-pp-cli multibuy chocolate --limit 3 --max-scan-pages 1 --agent

Agent-native plumbing

• basket — Prices a whole shopping list, showing which lines moved since the last time you ran it and what it did to the total.

  Use this to turn a plain-text list into a costed, decided answer in one call instead of dozens of searches.

  woolworths-pp-cli basket ./groceries.txt --record=false --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.

Finding the right command

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

woolworths-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

Check a special before you buy

woolworths-pp-cli real-special "tim tam" --agent

Returns a verdict per matching product rather than a price you have to interpret.

Narrow a large search for an agent

woolworths-pp-cli products search --term milk --agent --select Products.Products.Name,Products.Products.Price,Products.Products.CupString

A bare search returns hundreds of KB; selecting three dotted paths keeps the response small enough to reason over.

Find a cheaper equivalent by real unit price

woolworths-pp-cli swap "olive oil" --limit 10 --agent

Normalises across per-100g and per-1L tiles so the ranking is honest.

See what changed on catalogue rollover

woolworths-pp-cli specials-diff --agent

Only the entrants and departures since your last sync, not the whole specials list.

Cost this week's list against last week's

woolworths-pp-cli basket ./groceries.txt --record=false --agent

Per-line movement plus a basket total compared with the previous run.

Auth Setup

The catalogue, specials, stores and guest trolley need no account at all - only browser-shaped headers and a cookie jar the CLI warms automatically on first call. Personal surfaces (saved lists, past shops) sit behind Auth0 universal login with MFA, so there is no username/password flow to automate. On macOS and Linux, 'auth login --chrome' imports an existing logged-in Chrome session. On Windows that import is unavailable (the underlying cookie reader does not support it), so saved lists and past shops cannot be used there; the rest of the CLI is unaffected.

Run woolworths-pp-cli doctor to verify setup.

Agent Mode

Add --agent to any command. Expands to: --json --compact --no-input --no-color.

• 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:

  woolworths-pp-cli categories list --agent

• 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 confirmation — --agent does not imply --yes; pass --yes separately only after the target, arguments, and side effects are clear

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

• Use per-kind env vars only when a specific kind must diverge: WOOLWORTHS_CONFIG_DIR, WOOLWORTHS_DATA_DIR, WOOLWORTHS_STATE_DIR, WOOLWORTHS_CACHE_DIR.

• Resolution order is per-kind env var, --home, WOOLWORTHS_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 woolworths-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": {
      "woolworths": {
        "command": "woolworths-pp-mcp",
        "env": {
          "WOOLWORTHS_HOME": "/srv/woolworths"
        }
      }
    }
  }

Fleet precedence: an inherited per-kind env var overrides an explicit --home for that kind. Use WOOLWORTHS_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 WOOLWORTHS_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.

Step 1: recall before any discovery

Before list/search/drill commands on a new user question, run:

woolworths-pp-cli recall "<user's question>" --agent

The response envelope:

{
  "query": "...",
  "normalized": "<normalized form>",
  "query_entities": ["..."],
  "found": true | false,
  "match_score": 0.0,
  "results": [
    { "resource_id": "...", "resource_type": "...", "venue": "...",
      "confidence": 2, "entity_match": "exact|partial|unknown",
      "source": "taught|preseed|pattern", "warnings": ["..."] }
  ],
  "mismatches": [ /* only when --debug-mismatches */ ],
  "warnings": [ /* top-level */ ],
  "candidates": [
    { "id": 12, "class": "flag_alias | playbook_candidate",
      "summary": "...", "sightings": 3, "last_seen": "...",
      "rationale": "...",
      "next_action": ["<trial command>", "woolworths-pp-cli learnings confirm 12"] }
  ],
  "playbook": {
    "query_family": "...",
    "playbook": {
      "steps": [ { "cmd": "<command with {slot} substitution>", "purpose": "..." } ],
      "entity_slots": ["$ENTITY"],
      "expected_tool_calls": 3
    },
    "slots_resolved": { "$ENTITY": { "token": "<live token>", "canonical": "<canonical>" } },
    "notes": "<workarounds + gotchas for this query family>"
  },
  "notes": "<duplicate surface for non-playbook callers>"
}

Empty-store short-circuit: if the store has no learnings, playbooks, or candidates yet (recall finds nothing and learnings list and learnings candidates are both empty), skip recall for the rest of this session instead of taxing every query; resume recall-first once something has been taught.

Step 2: decision tree

Read candidates, playbook, notes, results[0], and warnings in that order:

if Candidates present (warnings include "candidates_present"):
    -> candidates are try-then-confirm, never facts. Follow each candidate's
       two-step next_action verbatim: run the trial command first, then run
       `learnings confirm <id>` only after the trial verified the behavior.
       Reject a wrong candidate with `learnings reject <id>`.
    -> NEVER re-teach something recall surfaced as a candidate; confirm or
       reject that candidate instead of teaching a duplicate.
    -> candidates ride alongside playbooks and resource hits, not instead of
       them; continue with the branches below after acting on them.

if Playbook present:
    -> READ Playbook.notes verbatim FIRST (workarounds + gotchas the CLI surface doesn't expose)
    -> replay Playbook.steps in order, substituting Playbook.slots_resolved entries
       for the entity slot tokens. If a step's slot is unresolved, fall back to
       discovery for that step only.
    -> the Playbook's expected_tool_calls is a budget; if you find yourself running
       materially more, record the divergence via `woolworths-pp-cli playbook amend`
       at end-of-session.

elif Notes present (no Playbook):
    -> read Notes verbatim before any discovery step; they carry known gotchas
       for this query family even when no structured choreography exists yet.

elif Found AND Results[0].EntityMatch == "exact" AND Results[0].Confidence >= 2:
    -> skip discovery; fetch live data for Results[*].ResourceID in parallel

elif Found AND Results[0].EntityMatch == "partial":
    -> candidate hint, NOT a hit; read the resource title to validate before trusting

elif (any row in Mismatches[] when --debug-mismatches was passed):
    -> treat as cold start; the stored learning is for a different entity
       (different canonical resolved from query_entities)

else:  // Found == false, no playbook, no notes
    -> cold start; run discovery normally; teach the answer afterward (Step 4).
       If the family has no playbook yet, that teach auto-synthesizes a
       playbook candidate from this session's journal - you do not need to
       record one by hand.

Playbook and Notes are orthogonal to the per-resource path. A recall response can carry both a Playbook AND a Results[] hit - use both: the Playbook tells you which choreography to run; the resource hits short-circuit specific steps. Default to skipping mismatches; pass --debug-mismatches only when investigating cold-start surprises.

Candidate judgment details: learnings confirm <id> prints the candidate's full payload before materializing it - check that the printed payload matches the behavior you verified. learnings reject <id> tombstones the derivation signature so the same candidate does not resurface. The envelope carries only the few candidates worth acting on now; woolworths-pp-cli learnings candidates lists the full open set.

Graceful degradation: if learnings confirm is an unknown command, you are driving an older binary - ignore the candidates guidance and follow the rest of the protocol.
