Evaluations
The evals/ directory contains trigger and functional evaluations for all skills.
# Run all evaluations (trigger + functional)
python3 evals/run_all.py -v
# Trigger evals only — tests if skills fire for the right queries (~3 min)
python3 evals/run_all.py --trigger-only -v
# Functional evals only — tests if skills produce correct output (~15 min)
python3 evals/run_all.py --functional-only -v
# Specific skills
python3 evals/run_all.py --skills text-to-speech agents -v
# Custom model (see `cursor-agent --list-models`)
python3 evals/run_all.py --model gpt-5.4-high -v
Results are saved to evals/results/<timestamp>/ with a report.md summary and results.json for programmatic access.
Functional evals use an isolated cursor-agent workspace per test case (under that results tree); they do not modify skill sources under each skill’s directory.
Requires the Cursor Agent CLI (cursor-agent on your PATH; override binary with CURSOR_AGENT) and Cursor authentication (cursor-agent login or CURSOR_API_KEY).
