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.
