Extract only the numerical values and their associated metrics from the text.
Format each as 'value: metric' on a new line.
Example format:
92: customer satisfaction
45%: revenue growth\
""",
        client=client,
    ),
)

converter = AgentSpec(
    "converter",
    new(
        ChatAgent,
        system="""\
Convert all numerical values to percentages where possible.
If not a percentage or points, convert to decimal (e.g., 92 points -> 92%).
Keep one number per line.
Example format:
92%: customer satisfaction
45%: revenue growth\
""",
        client=client,
    ),
)

sorter = AgentSpec(
    "sorter",
    new(
        ChatAgent,

Sort all lines in descending order by numerical value.
Keep the format 'value: metric' on each line.
Example:
92%: customer satisfaction
87%: employee satisfaction\
""",
        client=client,
    ),
)

formatter = AgentSpec(

    new(

Format the sorted data as a markdown table with columns:
| Metric | Value |
|:--|--:|
| Customer Satisfaction | 92% |\
