waza-runner

waza-runner is a skill for Claude Code, Codex from microsoft/waza. It costs 93 tokens per session (626 once invoked), scanned A, original, MIT.

An evaluation runner for testing agent skills. It checks whether a skill activates for the right requests, completes its tasks, and follows expected behavior.

In plain words
What is it for?
Use it to run evaluations, create evaluation suites, test skill triggers, and generate reports for development or continuous integration.
Why use it?
It turns vague skill testing into repeatable checks and reports, making problems easier to find before a skill is used in practice.

Written for no agent in particular: nothing here depends on one.

About the project

microsoft/waza is a Go command-line tool for building and evaluating AI agent skills through test suites, benchmarks, and model comparisons. It is for developers who need to measure and improve how reliably agent skills work. The catalogue entries are Waza's own skills, instructions, agent, and MCP integration.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

waza-runner scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Skill Eval Runner

Evaluate Agent Skills like you evaluate AI Agents

This skill runs evaluations on other skills to measure their effectiveness using the same patterns that power AI agent evaluations.

When to Use

  • Running quality evaluations on a skill
  • Testing if a skill triggers on correct prompts
  • Measuring skill behavior quality
  • Generating eval reports for CI/CD

Commands

Run Evals

Run evals on <skill-name>

Initialize Eval Suite

Create evals for <skill-name>

Generate Report

Generate eval report for <skill-name>

Workflow

  1. Check for Eval Suite: Look for eval.yaml in the skill directory
  2. Load Tasks: Parse task definitions from tasks/*.yaml
  3. Execute: Run each task through the configured graders
  4. Report: Output results in JSON or Markdown format

Metrics Measured

Metric Description Default Threshold
Task Completion Did the skill accomplish the goal? 80%
Trigger Accuracy Was skill invoked on correct prompts? 90%
Behavior Quality Tool calls, efficiency, reasoning 70%

Grader Types

  • Code Graders: Deterministic assertions, regex matching
  • LLM Graders: Model-as-judge with configurable rubrics
  • Human Graders: Manual review workflow

Example Usage

Running Evals

# From CLI
waza run ./my-skill/eval.yaml

# Output to file
waza run ./my-skill/eval.yaml -o results.json

Interpreting Results

{
  "summary": {
    "pass_rate": 0.85,
    "composite_score": 0.82
  },
  "metrics": {
    "task_completion": { "score": 0.9, "passed": true },
    "trigger_accuracy": { "score": 0.95, "passed": true }
  }
}

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
