• Handling huge version lists or truncated responses? Read:

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.
