01 — TL;DR
If you need output specificity above all else, pick orbit-general (4.5/5). experimental-design (4.3/5) is a reasonable alternative if you're already in its source ecosystem. They overlap in agent skill territory.
Side by side
4.3/5
4.5/5
Where they differ
- Trigger clarity. trigger clarity: experimental-design is clearly stronger (5.0 vs 4.5). For workloads where this dimension matters, prefer experimental-design.
- Output specificity. output specificity: a meaningful gap. orbit-general scores 3.5 vs 4.5 for the other. If you need this dimension, orbit-general is the right pick.
- Scope precision. scope precision: orbit-general is clearly stronger (4.5 vs 5.0). For workloads where this dimension matters, prefer orbit-general.
- Self-containment. self-containment: orbit-general is clearly stronger (4.0 vs 4.5). For workloads where this dimension matters, prefer orbit-general.
- Reusability. reusability: experimental-design is clearly stronger (4.0 vs 3.5). For workloads where this dimension matters, prefer experimental-design.
Which to pick
When to choose experimental-design
- Your workload emphasizes trigger clarity — experimental-design scores 5.0 vs 4.5 here.
- Your workload emphasizes reusability — experimental-design scores 4.0 vs 3.5 here.
- The agent skill convention you're working in matches experimental-design's scope.
When to choose orbit-general
- Your workload emphasizes output specificity — orbit-general scores 3.5 vs 4.5 here.
- Your workload emphasizes scope precision — orbit-general scores 4.5 vs 5.0 here.
- Your workload emphasizes self-containment — orbit-general scores 4.0 vs 4.5 here.
- You weight community adoption — orbit-general's upstream repo has 80,614 stars vs 28,193.
Scenario by scenario
| Scenario | Winner | Why |
|---|---|---|
| Agent must auto-select between many agent skills | experimental-design | Trigger clarity decides — clearer triggers reduce routing errors. |
| Output must be a specific file format or structured data | orbit-general | Output specificity determines whether downstream tools can rely on the result. |
| Skill must be readable and complete out of the box | orbit-general | Self-containment matters when you're not the original author. |
| Cross-team or cross-project reuse expected | experimental-design | Reusability separates one-off scripts from durable building blocks. |
Common questions
- Which is better, experimental-design or orbit-general?
- orbit-general ranks higher overall (4.5 vs 4.3 on our 0–5 rubric). That said, the better choice depends on which dimensions matter most for your use case.
- Are experimental-design and orbit-general both free to use?
- Both skills are free and open-source (or freely licensed). experimental-design: See source repo. orbit-general: 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 experimental-design and orbit-general 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?
- experimental-design is sourced from skillsmp.com (curated marketplace). orbit-general is sourced from skillsmp.com (curated marketplace). We verify each skill across multiple sources where possible; experimental-design appears in 1 source, orbit-general in 1.
