"""Rank open issues by how much they deserve a maintainer's attention.
|
|
|
|
Facts are computed in code: who opened the issue and what their history in
|
|
the repository and across GitHub looks like, when it was opened relative to
|
|
the releases around it, whether a maintainer has replied, and whether a fix
|
|
is already linked. Judgment calls about the text (what kind of report it is,
|
|
whether it has a reproduction, how severe it reads, whether it is security
|
|
sensitive) go to a judge: TypeSafe's Jev (`--judge jev`, TYPESAFE_API_KEY),
|
|
OpenAI's luna (`--judge luna`, OPENAI_API_KEY), or none. The default,
|
|
`--judge auto`, picks the first one with a key.
|
|
|
|
Each component is a number in [0, 1] and the score is their weighted sum, so
|
|
every rank comes with the reasons that produced it. Weights live in
|
|
`DEFAULT_WEIGHTS` and can be overridden with `--weights file.json`.
|
|
|
|
Issue text is untrusted input. The judges only rank; nothing here acts on
|
|
an issue.
|
|
|
|
Usage:
|
|
uv run scripts/rank_issues.py --repo PrefectHQ/fastmcp --limit 50
|
|
uv run scripts/rank_issues.py --judge luna --json ranked.json --explain 10
