What JFrog Artifactory does that npm does not
JFrog Artifactory passes clear canonical domain, clear product positioning, llms.txt published, llms-full.txt / full agent docs, agent-compatible signup flow, observable execution, and npm fails them. That is the whole of the gap between the two scores, so if none of those matter to your agent the ranking above overstates the difference.
Why people look for an alternative
npm fails clear canonical domain, clear product positioning, llms.txt published, llms-full.txt / full agent docs, openapi / spec quality, authentication documented, request examples provided, response examples provided, errors and status codes documented, limits / constraints documented, agent-compatible signup flow, programmatic credential creation, structured, predictable output, machine-readable errors, retry behavior documented, idempotency support, rate-limit behavior predictable, observable execution. Each one is a place an unattended run stops, which is usually what sends someone looking in the first place.
Where npm loses the points
| Pillar | npm | What it measures |
|---|---|---|
| Discover | 67 | Can an agent find it at all: sitemap, robots, structured data. |
| Understand | 38 | Is there a spec, an llms.txt, a machine-readable description. |
| Adopt | 80 | Signup, keys, SDKs, and whether a human has to be involved. |
| Operate | 41 | Rate-limit headers, errors, status, and behaviour under load. |
npm is weakest on understand at 38/100. Without a spec an agent has to guess at endpoints, and it guesses wrong. If that is the part your agent depends on, take the ranking above seriously; if it is not, npm may still be the right pick.
What an agent runs into with npm
These are the findings from the last audit on 2026-08-25. Each one is a place unattended software stops, which is the practical reason to look at the list above.
- Flesh out the OpenAPI: paths, schemas, and descriptions.
- Document error responses as an enum in your OpenAPI.
- Let agents create API keys programmatically.
- Return X-RateLimit / Retry-After headers so agents pace themselves.
- Return request IDs and expose status/usage so runs are observable.
- Add /llms.txt so agents can find and read your capabilities.
- Publish an AGENTS.md or llms-full.txt with full agent context.
- Add request examples to your API reference.
