AC exchange-rates
Fetch live exchange rates between any currency pairs from XE.com. Use when: user asks about currency conversion, exchange rates, forex rates, or converting amounts between currencies (e.g., "USD to INR", "100 EUR in GBP", "what's the dollar rate", "how much is 500 euros"). Don't use when: user asks about stock prices, crypto prices, or financial markets — those are web searches, not currency conversions. Output: JSON with rate, converted amount, and source. Present cleanly with unit rate and total.
As a process C 53/100 · Has gaps — weak spots: inputs and preconditions, failures and branches, consistency
How to improve
- Your own cases (evals/evals.json, 4–6 real requests with expected answers): the full check would then run those instead of a model-drafted suite.
- A spec.yaml with trigger phrases and assertions — a behaviour contract for CI; `skilltest init` writes a template.

Against the Agent Skills spec
- note
frontmatter-keyunknown frontmatter key "requires_env"
Process rating: all ten parameters 53/100
- 0Inputs and preconditions. Does not say what the process needs to start
- 0Failures and branches. Linear process with no failure handling
- 0Progress reporting. Says nothing while it works
- 40Consistency. Frontmatter name (exchange-rates) differs from the folder (abe-exchange-rates)
- 50When it triggers. No condition that starts the skill
- 60Tools and files. Uses tools (web) that frontmatter does not declare
- 60Result and completion. Output format stated, no completion criterion
- 100Steps. 9 steps
- 100Execution cost. Instruction body is 281 tokens
- 100Running it twice. No mutating operations
Everything here is measured from the skill text rather than judged by a model, so the numbers are checkable. A parameter weighs more when it is a more common reason for the process to stall.
