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 | $0.00023 | $0.00265 |
| Opus 5 | $0.00012 | $0.00133 |
| Sonnet 5 | $0.00005 | $0.00053 |
| Haiku 4.5 | $0.00002 | $0.00026 |
Grade A, and why
currency-converter 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 4d 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
currency-converter
Use this skill when the user asks to convert a monetary amount from one fiat currency to another (for example, "convert 100 USD to EUR").
This is a demonstration skill. It does not consult any live
exchange-rate API and ships no helper script; the agent surfaces
a canned mid-market rate and the converted amount inline, so the
demo catalog has a second skill to rank against
apigee-policy-top10 without consuming external quota.
When invoked, do this:
- Surface a stub response to the user in the form
currency-converter: stub conversion -- <amount> <FROM> -> <converted> <TO>using a plausible canned mid-market rate (e.g. 1 USD ≈ 0.92 EUR). - Explicitly tell the user this is a demonstration skill that does
NOT consult a live exchange-rate provider; production use would
require wiring a real exchange-rate API and adding the
corresponding
runtime_iampermissions.
What ships with it
1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

currency-converter is a skill published in the GitHub repository apigee/devrel (220 stars, last pushed 21d ago), licensed Apache-2.0. It adds 23 tokens to every session and 265 once invoked, about $0.0001 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.

Use to detect whether any GCP project has experienced an abnormal spend spike in the recent past, indicating possible API-key abuse or compromised credentials. READ-ONLY. Use standalone or as Phase 1b of gcp-ironclad.
cost-change-investigation
Use when investigating a cost change to explain what changed, when, and the best-supported drivers with contribution, timing, usage, metric, event, alert, and terminology evidence. Call getskill with skillId "cost-change-investigation" before starting the investigation.
virtual-dimensions
