skillgrade-setup

name	skillgrade-setup
description	Sets up and runs skillgrade evaluation pipelines for Agent Skills. Use when initializing eval configurations, running trials, reviewing results, or integrating with CI. Don't use for writing grader scripts, general test authoring, or non-agentic documentation.

Skillgrade Evaluation Setup

Procedures

Step 1: Install Skillgrade

1. Verify Node.js 20+ and Docker are available.
2. Run npm i -g skillgrade to install the CLI globally.

Step 2: Initialize an Eval Configuration

1. Navigate to the skill directory (must contain a SKILL.md).
2. Set the appropriate API key environment variable (GEMINI_API_KEY, ANTHROPIC_API_KEY, or OPENAI_API_KEY).
3. Run skillgrade init to generate an eval.yaml with AI-powered tasks and graders.
4. If an eval.yaml already exists, pass --force to overwrite: skillgrade init --force.
5. Without an API key, a well-commented template is generated instead.

Step 3: Configure eval.yaml

1. Read references/eval-yaml-spec.md for the full configuration schema.
2. Define one or more tasks under the tasks: key. Each task requires:
   • name: unique task identifier
   • instruction: what the agent should accomplish
   • workspace: files to copy into the evaluation container
   • graders: one or more scoring mechanisms (see the skillgrade-graders skill)
3. Optionally configure defaults: for agent, provider, trials, timeout, and threshold.

Step 4: Run Evaluations

1. Select an appropriate preset based on the evaluation goal:
   • --smoke (5 trials): Quick capability check.
   • --reliable (15 trials): Reliable pass rate estimate.
   • --regression (30 trials): High-confidence regression detection.
2. Run the evaluation: skillgrade --smoke.
3. Run a specific eval by name: skillgrade --eval=fix-linting.
4. Run multiple evals: skillgrade --eval=fix-linting,write-tests.
5. Run only deterministic graders (skip LLM calls): skillgrade --grader=deterministic.
6. Run only LLM rubric graders: skillgrade --grader=llm_rubric.
7. The agent is auto-detected from the API key. Override with --agent=gemini|claude|codex|acp|opencode|command.
8. For ACP, pass --acp-command="gemini --acp" or set defaults.acp.command.
9. For OpenCode, pass --opencode-agent=build|plan|explore or --opencode-model=provider/model.
10. For a custom agent, pass --agent=command --command="node mycli.js" or set defaults.command. The instruction is piped to the command's stdin.
11. Override the provider with --provider=docker|local.

Step 5: Review Results

1. Run skillgrade preview for a CLI report.
2. Run skillgrade preview browser to open the web UI at http://localhost:3847.
3. Reports are saved to $TMPDIR/skillgrade/<skill-name>/results/. Override with --output=DIR.

Step 6: Integrate with CI

1. Add a GitHub Actions step that installs skillgrade, navigates to the skill directory, and runs with --regression --ci --provider=local.
2. Use --provider=local in CI — the runner is already an ephemeral sandbox, so Docker adds overhead without benefit.
3. The --ci flag causes a non-zero exit code if the pass rate falls below --threshold (default: 0.8).
4. Read references/ci-example.md for a complete workflow template.

Error Handling

• If skillgrade init fails with "No SKILL.md found," verify the current directory contains a valid SKILL.md file.
• If evaluation hangs, check Docker is running and the container has network access for API calls.
• If all trials fail with "No API key," ensure the environment variable is exported, not just set inline for a different command.
