/evaluate:plugin

Batch evaluate all skills in a plugin. Runs /evaluate:skill for each skill, then produces a plugin-level quality report.

When to Use This Skill

Use this skill when...	Use alternative when...
Auditing all skills in a plugin before release	Evaluating a single skill -> /evaluate:skill
Establishing quality baselines across a plugin	Viewing past results -> /evaluate:report
Checking overall plugin quality after refactoring	Need structural compliance -> plugin-compliance-check.sh

Context

• Plugin skills: !find $1/skills -name "SKILL.md" -maxdepth 3
• Existing evals: !find $1/skills -name "evals.json" -maxdepth 3

Parameters

Parse these from $ARGUMENTS:

Parameter	Default	Description
<plugin-name>	required	Name of the plugin to evaluate
--create-missing-evals	false	Generate evals for skills that lack them
--parallel N	1	Max concurrent skill evaluations

Execution

Step 1: Discover skills

Find all skills in the plugin:

<plugin-name>/skills/*/SKILL.md

List them and count the total.

Step 2: Filter and prepare

For each skill, check if evals.json exists:

• Has evals: include in evaluation
• No evals + --create-missing-evals: include, will create evals during evaluation
• No evals, no flag: skip with a note

Report the breakdown:

Found N skills in <plugin-name>:
  - M with eval cases
  - K without eval cases (skipped | will create)

Step 3: Run evaluations

For each included skill, invoke /evaluate:skill via the SlashCommand tool:

SlashCommand: /evaluate:skill <plugin-name>/<skill-name> [--create-evals]

If --parallel N is set and N > 1, batch evaluations into groups of N. Otherwise, run sequentially.

Track progress with TodoWrite — mark each skill as it completes.

Step 4: Aggregate plugin report

After all skill evaluations complete, read each skill's benchmark.json and aggregate:

bash evaluate-plugin/scripts/aggregate_benchmark.sh <plugin-name>

Write aggregated results to <plugin-name>/eval-results/plugin-benchmark.json.

Step 5: Report

Print a plugin-level summary table:

## Plugin Evaluation: <plugin-name>

| Skill | Evals | Pass Rate | Status |
|-------|-------|-----------|--------|
| skill-a | 4 | 100% | PASS |
| skill-b | 3 | 67% | PARTIAL |
| skill-c | 5 | 80% | PASS |

**Overall**: 82% pass rate across N eval cases

Rank skills by pass rate. Flag any below 50% as needing attention.

Agentic Optimizations

Context	Command
List plugin skills	ls -d <plugin>/skills/*/SKILL.md
Check for evals	find <plugin>/skills -name evals.json
Count skills	ls -d <plugin>/skills/*/SKILL.md | wc -l
Aggregate results	bash evaluate-plugin/scripts/aggregate_benchmark.sh <plugin>

Quick Reference

Flag	Description
--create-missing-evals	Generate eval cases for skills without them
--parallel N	Max concurrent evaluations (default: 1)
