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.

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 | $0.00036 | $0.00426 |
| Opus 5 | $0.00018 | $0.00213 |
| Sonnet 5 | $0.00007 | $0.00085 |
| Haiku 4.5 | $0.00004 | $0.00043 |
Grade A, and why
rest-countries scanned grade A with 0 findings 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 5d 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.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
rest-countries
Generated by Gutenberg. Use this skill to call the rest-countries API through the local rest-countries CLI.
When to use
- The user asks for data exposed by rest-countries (v3.1).
- An agent task needs structured JSON from https://restcountries.com.
- You need to perform a write/destructive operation on rest-countries — always preview first, run with
--yesonly on explicit user confirmation.
How to invoke
The skill assumes the generated CLI is on PATH (or invoke via scripts/use-go.sh run ./cmd/rest-countries from the project directory).
rest-countries operations
rest-countries call getNameItaly --json
rest-countries sync --json
rest-countries search "<keyword>" --json
Authentication
No authentication required.
Operations index
getNameItaly(GET /v3.1/name/italy) — read — GET /v3.1/name/italygetRegionEurope(GET /v3.1/region/europe) — read — GET /v3.1/region/europegetIndependent(GET /v3.1/independent) — read — GET /v3.1/independent
Output contract
- All commands accept
--jsonand emit machine-readable output. callreturns{ dryRun, operation, request, response }.dryRun: truemeans the call was not executed (write op without--yes).searchreturns cached records.syncpopulates the local SQLite cache.

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.

rest-countries is a skill published in the GitHub repository JustVugg/tools-factory (52 stars, last pushed 2mo ago), licensed MIT. It adds 36 tokens to every session and 426 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
