Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00182 | $0.00182 |
| Opus 5 | $0.00091 | $0.00091 |
| Sonnet 5 | $0.00036 | $0.00036 |
| Haiku 4.5 | $0.00018 | $0.00018 |
Grade A, and why
worldbank-api CLAUDE.md scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Not a fault in itself. Listed so you know the mod talks to something, and to what.
live API (`curl "https://api.worldbank.org/v2/...?format=json"`) before What it actually says
CLAUDE.md
Follow the repository conventions in AGENTS.md — it is the single source of truth for layout, style rules, and the pre-commit validation checklist.
Quick reminders for Claude Code sessions:
- All committed files are English-only; conversation language is unrestricted.
- Test every documented endpoint, parameter, and indicator code against the
live API (
curl "https://api.worldbank.org/v2/...?format=json") before writing it down — indicator codes get archived without notice. - The skill lives in
skills/worldbank-api/; editSKILL.mdfor workflow-level guidance,references/for the endpoint catalog and indicator code lists, andscripts/wb_data.pyfor the bundled CLI. - Default stance is the free, keyless API — there is no paid tier to document.
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
