01 — TL;DR
If you need self-containment above all else, pick notion-spec-to-implementation (3.5/5). export (4.2/5) is a reasonable alternative if you're already in its source ecosystem. They overlap in agent skill territory.
Side by side
4.2/5
Where they differ
- Trigger clarity. trigger clarity: export and notion-spec-to-implementation score essentially the same (4.5 vs 4.5). Neither has an edge here.
- Output specificity. output specificity: export and notion-spec-to-implementation score essentially the same (4.5 vs 4.5). Neither has an edge here.
- Scope precision. scope precision: export and notion-spec-to-implementation score essentially the same (4.5 vs 4.5). Neither has an edge here.
- Self-containment. self-containment: a meaningful gap. notion-spec-to-implementation scores 3.5 vs 4.5 for the other. If you need this dimension, notion-spec-to-implementation is the right pick.
- Reusability. reusability: export and notion-spec-to-implementation score essentially the same (3.5 vs 3.5). Neither has an edge here.
Which to pick
When to choose export
- You weight community adoption — export's upstream repo has 60,289 stars vs 19,581.
- The agent skill convention you're working in matches export's scope.
When to choose notion-spec-to-implementation
- Your workload emphasizes self-containment — notion-spec-to-implementation scores 3.5 vs 4.5 here.
- You prefer the official source — notion-spec-to-implementation comes from github:openai/skills, export from skillsmp.com.
- The agent skill convention you're working in matches notion-spec-to-implementation's scope.
Scenario by scenario
| Scenario | Winner | Why |
|---|---|---|
| Agent must auto-select between many agent skills | either | Trigger clarity decides — clearer triggers reduce routing errors. |
| Output must be a specific file format or structured data | either | Output specificity determines whether downstream tools can rely on the result. |
| Skill must be readable and complete out of the box | notion-spec-to-implementation | Self-containment matters when you're not the original author. |
| Cross-team or cross-project reuse expected | either | Reusability separates one-off scripts from durable building blocks. |
Common questions
- Which is better, export or notion-spec-to-implementation?
- export ranks higher overall (4.2 vs 3.5 on our 0–5 rubric). That said, the better choice depends on which dimensions matter most for your use case.
- Are export and notion-spec-to-implementation both free to use?
- Both skills are free and open-source (or freely licensed). export: See source repo. notion-spec-to-implementation: 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 export and notion-spec-to-implementation 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?
- export is sourced from skillsmp.com (curated marketplace). notion-spec-to-implementation is sourced from github:openai/skills (official). We verify each skill across multiple sources where possible; export appears in 1 source, notion-spec-to-implementation in 1.
