What it does

Pp World Bank is an agent skill from mvanhorn/printing-press-library. Every World Bank indicator, queryable offline, with cross-country SQL and rankings no wrapper has. Trigger phrases: world bank gdp for, compare gdp across countries, find world bank indicator, rank countries by, development indicators for, use world-bank, run world-bank.

Its SKILL.md is about 3k 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 Data & Analytics. It works with SQL. 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

  • Phrases: world bank gdp for
  • Compare gdp across countries
  • Find world bank indicator
  • Rank countries by

Example prompts

  • “/pp-world-bank”

Requirements

  • Python 3
  • Node.js
  • 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: world-bank-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 no API keys, tokens, secrets or passwords.

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

Context cost

Pp World Bank loads about 3k tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 1,173 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~75
When it runs · the whole SKILL.md, loaded when a task matches
~3k

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.

World Bank — Printing Press CLI

Prerequisites: Install the CLI

This skill drives the world-bank-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 world-bank --cli-only
  2. Verify: world-bank-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 1.26.4 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/other/world-bank/cmd/world-bank-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.

A single-binary CLI for the World Bank Open Data API. Mirrors the ~16,000-indicator catalog and observations into local SQLite for offline search, then adds cross-country compare, rankings, trend stats, and pipeline exports the Python wrappers and MCP shims don't offer. No API key — World Bank is fully public.

When to Use This CLI

Reach for this CLI when an agent or script needs World Bank development indicators: GDP, population, emissions, poverty, health, education time-series; cross-country comparisons; or rankings. It is ideal for data-pipeline extracts and offline indicator discovery.

Anti-triggers

Do not use this CLI for:

  • Real-time market/financial prices (use a markets API)
  • US-specific Federal Reserve series (use FRED)
  • Sub-national or city-level data not in World Bank indicators

Unique Capabilities

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

Offline catalog

  • indicators find — Search the full ~16,000-indicator catalog by keyword in a single call.

    Agents discover the exact indicator code before fetching values, in one local call.

    bash
    world-bank-pp-cli indicators find "co2 emissions" --json
Local joins

  • compare — Line up one indicator across many countries in a single aligned table with deltas vs a baseline.

    One call answers 'how do these economies compare' without N separate fetches.

    bash
    world-bank-pp-cli compare NY.GDP.MKTP.CD USA,CHN,IND --date 2024 --agent

  • trend — CAGR, year-over-year change, min/max/latest for one country+indicator series.

    Agents get the trajectory summary directly instead of parsing decades of rows.

    bash
    world-bank-pp-cli trend USA NY.GDP.MKTP.CD --window 10 --agent

  • rank — Rank all economies by an indicator for a year, filtered by region or income level.

    Find leaders/laggards on any indicator in one call.

    bash
    world-bank-pp-cli rank NY.GDP.PCAP.CD --year 2024 --top 10 --income HIC --agent
Data pipeline

  • export — Bulk country x indicator pull emitted as pipeline-ready wide or long CSV.

    Drops straight into notebooks, sheets, and ETL without reshaping.

    bash
    world-bank-pp-cli export USA,CHN NY.GDP.MKTP.CD,SP.POP.TOTL --wide --csv

  • data diff — Compare a fresh pull against the last synced snapshot to surface revised observations.

    Detect World Bank data revisions between vintages automatically.

    bash
    world-bank-pp-cli data diff USA NY.GDP.MKTP.CD --agent

Command Reference

countries — Economies (countries and aggregates) with region, income level, lending type

  • world-bank-pp-cli countries get — Get one economy by ISO code (e.g. USA, BRA)
  • world-bank-pp-cli countries list — List economies

  • world-bank-pp-cli topics indicators — List indicators under a topic
  • world-bank-pp-cli topics list — List topics
Finding the right command

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

bash
world-bank-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

Find then fetch
bash
world-bank-pp-cli indicators find "life expectancy" --json --select id,name

Discover the code, then pass it to data fetch.

Compact cross-country GDP
bash
world-bank-pp-cli compare NY.GDP.MKTP.CD USA,CHN,IND,DEU --date 2024 --agent --select country.value,date,value

Narrow a deeply nested response to just the fields that matter.

Top economies by GDP per capita
bash
world-bank-pp-cli rank NY.GDP.PCAP.CD --year 2024 --top 10 --income HIC

Rank and filter in one call.

Pipeline export
bash
world-bank-pp-cli export USA,CHN NY.GDP.MKTP.CD,SP.POP.TOTL --wide --csv

Wide CSV ready for a notebook.

Auth Setup

No authentication required.

Run world-bank-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
    world-bank-pp-cli countries 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

  • 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": "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:

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

Entries are stored locally at ~/.local/share/world-bank-pp-cli/feedback.jsonl. They are never POSTed unless WORLD_BANK_FEEDBACK_ENDPOINT is set AND either --send is passed or WORLD_BANK_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.

world-bank-pp-cli profile save briefing --json
world-bank-pp-cli --profile briefing countries list
world-bank-pp-cli profile list --json
world-bank-pp-cli profile show briefing
world-bank-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
5API error (upstream issue)
7Rate limited (wait and retry)
10Config error

Argument Parsing

Parse $ARGUMENTS:

  1. Empty, help, or --help → show world-bank-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/other/world-bank/cmd/world-bank-pp-mcp@latest
  2. Register with Claude Code:
    bash
    claude mcp add world-bank-pp-mcp -- world-bank-pp-mcp
  3. Verify: claude mcp list

Direct Use

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