deps.dev (Skill Router)
This file is intentionally introductory.
Open the right note under references/ based on what you need.
Start here (fast)
- Need the latest/default version of a known package? Read:
references/latest-version.md.
- Handling huge version lists or truncated responses? Read:
references/large-responses.md.
- Not sure how to format/normalize package names per ecosystem? Read:
references/naming-and-encoding.md.
- Need endpoint shapes and fields to parse? Read:
references/api.md.
Primary recipe (one request)
Goal: given {system, packageName}, return the default/latest version.
- Call GetPackage:
GET https://api.deps.dev/v3/systems/{SYSTEM}/packages/{PACKAGE}
- Parse
versions[] and select the item with isDefault=true.
If isDefault is missing for all versions, stop and ask for an explicit selection rule (e.g., include pre-releases or not) instead of guessing.
Critical prohibitions
- Do not guess the “latest” version by string sorting.
- Do not output placeholder or “approximate” versions; always wait for API data.
- Do not parse large JSON via
grep or manual truncation; use a JSON parser (jq/Python/Node).
- Do not silently fall back when
isDefault is missing; ask for the desired rule.
- Do not paste large verbatim chunks from docs; summarize.
- Do not assume auth or rate limits; treat them as unspecified unless you have evidence.
