Pakistan Bureau of Statistics — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the pbs-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 pbs --cli-only

2. Verify: pbs-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/other/pbs/cmd/pbs-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.

Pakistan Bureau of Statistics publishes the richest sub-national price data in the country one machine-hostile weekly file at a time, indexes those files in a hand-edited JavaScript array, and deletes its own history: its live index reaches further back than the Internet Archive does, and one monthly annex is already served under two different months so one of them is lost. This CLI turns those scattered releases into one queryable panel and records every gap as a gap. Use spread and drift for questions the source cannot answer at all, coverage and verify to audit what you have, and revisions to catch what the Bureau quietly changed.

When to Use This CLI

Use this CLI for any question about Pakistani consumer prices that spans more than one release file: comparing an item across cities, following an item over weeks, building a custom weighted index, or auditing how complete a price series actually is. It is also the right tool when you need to prove what the Bureau published at a point in time, because it stores what the site later overwrites. Prefer it over reading the source files by hand whenever the answer needs more than one week.

Anti-triggers

Do not use this CLI for:

• Do not use this CLI to fill in a missing week or estimate a price the Bureau did not publish; it reports gaps and will not interpolate.
• Do not use it for a provincial or regional average; the Bureau does not publish the city weight vector, so any such figure would look official and be wrong.
• Do not use it for Pakistani price history before July 2023; the older base series is no longer served and returns HTTP 404.
• Do not use it for national headline inflation commentary alone, where the Bureau's own published index is the citable figure.
• Do not use it for wage, fertilizer, cement or CNG series in this version; those sub-tables cover a different city set and are not yet parsed.

Unique Capabilities

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

Panel joins the source cannot answer

• spread — See the cheapest and dearest city for any essential item in any week, and how that gap has moved over time.

  Reach for this when the question is about geography rather than time — which city is an outlier on this item right now.

  pbs-pp-cli spread "Onions" --as-of 2026-09-03 --agent

• drift — Follow one item's price across named cities and weeks, with missing weeks shown as gaps rather than filled.

  Reach for this when the question is about time for a known item and known cities.

  pbs-pp-cli drift "Wheat Flour Bag" --city lahore --city quetta --agent

• basket — Build your own price index over any subset of items using the weight vector PBS republishes every week.

  Reach for this to build a food-only or fuel-only index the Bureau never computes.

  pbs-pp-cli basket --item "Wheat Flour Bag" --item "Sugar Refined" --weight lowest --agent

• movers — Rank every item in a release by percent change recomputed from price levels, nationally or per city, with outliers flagged.

  Reach for this when the question is which items moved this week, rather than one known item.

  pbs-pp-cli movers --as-of 2026-09-03 --top 10 --flag-outliers --agent

Only the accrued store knows

• weights — Read the item weight vector for any release, diff two releases, and check the totals sum to 100.

  Reach for this before trusting a long index series — a silent re-weighting breaks comparability.

  pbs-pp-cli weights --check-total --agent

• revisions — Detect releases the Bureau has rewritten, re-pointed, or deleted since you captured them.

  Reach for this to prove your local copy is the surviving record, and to catch a silent restatement.

  pbs-pp-cli revisions --all --agent

Honesty instrumentation

• verify — Audit parsed cell values against the source's own arithmetic invariants, including the weight totals and min-avg-max ordering.

  Reach for this before quoting any figure — it distinguishes a real price move from a parse bug.

  pbs-pp-cli verify --all --agent

• coverage — Show which releases exist upstream, which the local store holds, and every hole named as a hole.

  Reach for this whenever a result looks clean — a silently short series is the classic false positive.

  pbs-pp-cli coverage --gaps --agent

Command Reference

file — Static annexure/report files. All 202 live in one flat directory; the filename is the only variable.

• pbs-pp-cli file <filename> — Fetch one annexure, report, or CPI annex file by exact filename. Formats: .

index — The PBS price-statistics release index. Carries TWO JavaScript literal arrays in the served HTML: data (148 weekly SPI releases, 2023-07-13..2026-09-03) and cpidata1 (50 CPI months, July 2022..August 2026).

• pbs-pp-cli index — Fetch the release-index page.

Finding the right command

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

pbs-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. --json (and other machine formats) keep that exit-2 contract and write {"matches":[]} on stdout so agents can inspect the envelope without treating a miss as success.

Recipes

Which city is gouging on onions this week

pbs-pp-cli spread "Onions" --as-of 2026-09-03 --agent --select summary.min_city,summary.max_city,summary.range,summary.contributing_cities

Narrows a wide cross-city payload to just the extremes and the count of cities that actually reported, so an agent does not spend context on all the per-city rows.

Food inflation for the poorest quintile

pbs-pp-cli basket --item "Wheat Flour Bag" --item "Sugar Refined" --item "Pulse Gram" --weight lowest --json

Rebuilds an index over a chosen food subset using the Bureau's own lowest-quintile weights, which it republishes every week but never applies to a custom basket.

Audit a series before quoting it

pbs-pp-cli coverage --gaps --state-census --json

Prints missing releases and the per-release census of zero, blank and N.A. cells, so a clean-looking result can be checked for a silently short sample.

Catch what the Bureau changed under you

pbs-pp-cli revisions --all --json

Compares stored file hashes and index rows against the live site to surface rewritten bytes, re-pointed filenames, and releases that now return 404.

Track how the basket itself was re-weighted

pbs-pp-cli weights --diff 2023-07-13..2026-09-03 --json

The weight vector ships in every release with no change log upstream, so this diff exists only because the local store kept both editions.

Auth Setup

No authentication required.

Run pbs-pp-cli doctor to verify setup.

Agent Mode

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

Global format flags share one contract on promoted, novel, sync, and --deliver paths:

• --json — one JSON document on stdout (sync progress events go to stderr)

• --compact — keep identity/status/timestamp fields; does not change the document vs stream shape

• --csv / --plain — tabular rows (collection envelopes unwrap to the row array)

• --quiet — one identity value per row, no envelope

• 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:

  pbs-pp-cli file mock-value --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

• 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:

{
  "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 PBS_HOME=<dir> to relocate all four path kinds under one root.

• Use per-kind env vars only when a specific kind must diverge: PBS_CONFIG_DIR, PBS_DATA_DIR, PBS_STATE_DIR, PBS_CACHE_DIR.

• Resolution order is per-kind env var, --home, PBS_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 pbs-pp-cli doctor --fail-on warn to surface path 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": {
      "pbs": {
        "command": "pbs-pp-mcp",
        "env": {
          "PBS_HOME": "/srv/pbs"
        }
      }
    }
  }

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

pbs-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>", "pbs-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 `pbs-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; pbs-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.
