First, summarize what it does, its dependencies, license status if identifiable, and any risks. Show the exact files you propose to add under .agents/skills/csv-analysis/. Do not write files or run scripts until I approve.

After I approve, install the complete skill folder, including required referenced files, into that project location. Verify it is discoverable, then tell me its actual invocation name and how to use it. Do not claim it is installed until you have verified it.

CSV Analysis Skill

Use this workflow when the user asks for analysis over a local CSV file.

Required Workflow

  1. Locate the CSV file from the user prompt.
  2. Read the full CSV file, not only the first few rows.
  3. Inspect the header, row count, missing values, and key categorical columns.
  4. If the task asks for failure rate, use:
failure_rate = number of rows where results == "Fail" / number of rows in the group
  1. When grouping by facility_type, include only groups that meet the user's minimum inspection-count threshold.
  2. Sort failure-rate results by:
failure_rate descending, inspection_count descending, facility_type ascending
  1. Generate the requested chart and save it to the exact output path.
  2. Write the requested Markdown report to the exact output path.
  3. Verify the result by checking:
source file path
total rows read
number of facility_type groups before and after filtering
chart file exists
report file exists

Output Expectations

For the demo task, create:

outputs/summary.md
outputs/failure_rate_by_facility.png

The report should include:

  • source file and row count
  • metric definition
  • top 10 facility types by failure rate
  • a short conclusion
  • a verification note
