Intent becomes instructions; instructions meet test prompts; evidence drives the next revision.

Capabilities
What can you do with Skill Creator?
Treat Skill authoring as an iterative product process.
Use this plugin when creating a new Skill or when an existing Skill triggers poorly, produces uneven work, or lacks evidence that revisions help.
- Capture intent, triggers, constraints, and expected workflow.
- Write and validate a focused SKILL.md.
- Create representative positive and negative test prompts.
- Run qualitative reviews and quantitative benchmarks.
- Package the Skill and iterate from observed failures.
Write for correct triggering
The name and description are treated as routing interfaces, while the body stays focused on the workflow and reusable resources.
Evaluate before claiming quality
Test prompts, graders, variance analysis, and review artifacts make improvements inspectable and reveal overfitting risks.
Practical workflow
From skill intent to evidence-backed package
Pass 01 / Author
Capture and encode the workflow
Clarify the task, triggers, tools, edge cases, and reusable assets, then write the smallest effective Skill.
Pass 02 / Evaluate
Test, compare, and refine
Run representative prompts, review outputs and scores, fix observed problems, and repeat with a broader test set.

What this plugin does
Skill Creator supports the complete Agent Skill lifecycle: intent capture, SKILL.md authoring, validation, test-prompt design, qualitative review, benchmarking, description improvement, packaging, and iterative refinement.
Practical workflow
Define what the Skill should do and when it should trigger. Write the smallest effective instructions and reusable resources, then test representative positive, negative, and edge prompts. Compare results, fix observed failures, and repeat with a broader test set.
Evaluation limits
Benchmark results depend on prompts, graders, models, and sampling variance. Do not treat a score as universal quality. Review bundled Python scripts before running them and avoid sensitive production data in evaluation fixtures.
Source
This portable package is maintained in agentplugin-net/portable-agent-plugins from a pinned Apache-2.0 upstream Skill.
