/skill-test Command

The /skill-test command provides an interactive CLI for testing Databricks skills with real execution on Databricks.

Basic Usage

/skill-test <skill-name> [subcommand]

Subcommands

Subcommand	Description
run	Run evaluation against ground truth (default)
regression	Compare current results against baseline
init	Initialize test scaffolding for a new skill
add	Interactive: prompt -> invoke skill -> test -> save
add --trace	Add test case with trace evaluation
review	Review pending candidates interactively
review --batch	Batch approve all pending candidates
baseline	Save current results as regression baseline
mlflow	Run full MLflow evaluation with LLM judges
trace-eval	Evaluate traces against skill expectations
list-traces	List available traces (MLflow or local)
scorers	List configured scorers for a skill
scorers update	Add/remove scorers or update default guidelines
sync	Sync YAML to Unity Catalog (Phase 2)

Quick Examples

/skill-test databricks-spark-declarative-pipelines run
/skill-test databricks-spark-declarative-pipelines add --trace
/skill-test databricks-spark-declarative-pipelines review --batch --filter-success
/skill-test my-new-skill init

See Workflows for detailed examples of each subcommand.

Execution Instructions

Environment Setup

uv pip install -e .test/

Environment variables for Databricks MLflow:

• DATABRICKS_CONFIG_PROFILE - Databricks CLI profile (default: "DEFAULT")
• MLFLOW_TRACKING_URI - Set to "databricks" for Databricks MLflow
• MLFLOW_EXPERIMENT_NAME - Experiment path (e.g., "/Users/{user}/skill-test")

Running Scripts

All subcommands have corresponding scripts in .test/scripts/:

uv run python .test/scripts/{subcommand}.py {skill_name} [options]

Subcommand	Script
run	run_eval.py
regression	regression.py
init	init_skill.py
add	add.py
review	review.py
baseline	baseline.py
mlflow	mlflow_eval.py
scorers	scorers.py
scorers update	scorers_update.py
sync	sync.py
trace-eval	trace_eval.py
list-traces	list_traces.py
_routing mlflow	routing_eval.py

Use --help on any script for available options.

Command Handler

When /skill-test is invoked, parse arguments and execute the appropriate command.

Argument Parsing

• args[0] = skill_name (required)
• args[1] = subcommand (optional, default: "run")

Subcommand Routing

Subcommand	Action
run	Execute run(skill_name, ctx) and display results
regression	Execute regression(skill_name, ctx) and display comparison
init	Execute init(skill_name, ctx) to create scaffolding
add	Prompt for test input, invoke skill, run interactive()
review	Execute review(skill_name, ctx) to review pending candidates
baseline	Execute baseline(skill_name, ctx) to save as regression baseline
mlflow	Execute mlflow_eval(skill_name, ctx) with MLflow logging
scorers	Execute scorers(skill_name, ctx) to list configured scorers
scorers update	Execute scorers_update(skill_name, ctx, ...) to modify scorers

init Behavior

When running /skill-test <skill-name> init:

1. Read the skill's SKILL.md to understand its purpose
2. Create manifest.yaml with appropriate scorers and trace_expectations
3. Create empty ground_truth.yaml and candidates.yaml templates
4. Recommend test prompts based on documentation examples

Follow with /skill-test <skill-name> add using recommended prompts.

Context Setup

Create CLIContext with MCP tools before calling any command. See Python API for details.

File Locations

Important: All test files are stored at the repository root level, not relative to this skill's directory.

File Type	Path
Ground truth	{repo_root}/.test/skills/{skill-name}/ground_truth.yaml
Candidates	{repo_root}/.test/skills/{skill-name}/candidates.yaml
Manifest	{repo_root}/.test/skills/{skill-name}/manifest.yaml
Routing tests	{repo_root}/.test/skills/_routing/ground_truth.yaml
Baselines	{repo_root}/.test/baselines/{skill-name}/baseline.yaml

For example, to test databricks-spark-declarative-pipelines in this repository:

/Users/.../ai-dev-kit/.test/skills/databricks-spark-declarative-pipelines/ground_truth.yaml

Not relative to the skill definition:

/Users/.../ai-dev-kit/.claude/skills/skill-test/skills/...  # WRONG
