Classify and Filter Skill

Classify and Filter

Applies deterministic regex rules to classify PRs, checks which files existed at the target release tag, detects subsystems, and filters out PRs that only touch post-release or non-runtime code.

Usage

python3 scripts/classify-and-filter.py \
  --input artifacts/backport-triage/raw-prs.json \
  --repo /path/to/vllm \
  --tag v0.13.0 \
  --output artifacts/backport-triage/filtered.json

Input

raw-prs.json — output of the vllm-backport-fetch-prs skill.

Output

filtered.json — same PR objects enriched with:

classification: runtime_bug, platform_specific, unclear, not_bugfix
verdict: CANDIDATE or SKIP
skip_reason: why skipped (if applicable)
files, files_in_release, files_new, files_in_release_count, files_total
subsystems: list of detected vLLM subsystem names

Agent Follow-up

After running this skill, review PRs with classification: "unclear". Read each PR's description and decide if it's a real bugfix. Override the classification in the JSON if needed.

Bugfix PRs in vLLM often have misleading titles — always check the actual diff and description, not just the title.
