01 — TL;DR
If you need output specificity above all else, pick agent-eval (4.2/5). author-contributions (3.2/5) is a reasonable alternative if you're already in its source ecosystem. They overlap in agent infrastructure piece territory.

Which to pick
When to choose agent-eval
- Your workload emphasizes output specificity — agent-eval scores 4.5 vs 4.0 here.
- Your workload emphasizes reusability — agent-eval scores 4.0 vs 3.5 here.
- The agent infrastructure piece convention you're working in matches agent-eval's scope.

- The agent infrastructure piece convention you're working in matches author-contributions's scope.
Scenario by scenario
| Scenario | Winner | Why |
|---|---|---|
| Agent must auto-select between many agent infrastructure pieces | either | Trigger clarity decides — clearer triggers reduce routing errors. |
| Output must be a specific file format or structured data | agent-eval | Output specificity determines whether downstream tools can rely on the result. |
| Skill must be readable and complete out of the box | author-contributions | Self-containment matters when you're not the original author. |
| Cross-team or cross-project reuse expected | agent-eval | Reusability separates one-off scripts from durable building blocks. |
Common questions
- Which is better, agent-eval or author-contributions?
- agent-eval ranks higher overall (4.2 vs 3.2 on our 0–5 rubric). That said, the better choice depends on which dimensions matter most for your use case.
- Are agent-eval and author-contributions both free to use?
- Both skills are free and open-source (or freely licensed). agent-eval: See source repo. author-contributions: See source repo. Installation has no cost; usage costs depend on the underlying LLM tokens consumed when you invoke the skill.
- Can I install both agent-eval and author-contributions at the same time?
- Yes. Agent skills are not exclusive — an agent runtime (Claude Code, Codex, etc.) can have many skills installed and route to whichever matches the current task. Installing both is a low-cost way to keep your options open.
- Where do these skills come from?
- agent-eval is sourced from skillsmp.com (curated marketplace). author-contributions is sourced from skillsmp.com (curated marketplace). We verify each skill across multiple sources where possible; agent-eval appears in 1 source, author-contributions in 1.
