Every issue opened from now on is gated on the template headings, sent once
through the LiteLLM proxy with a strict JSON schema, and labelled from the
manifest in .github/labels.json. Old-template issues are not touched. The bug
template shrinks to Description, Config, LiteLLM Version and Steps to Repro,
both templates gain a domain dropdown, and the labelers that keyed off the old
component dropdown go away.
The flag step never read it: parseVerdict destructures duplicate_of,
confidence and evidence only, so considered cost tokens on every issue
and went straight on the floor. The parse test now covers extra keys
being dropped instead of asserting a field that no longer exists.
The old check_duplicate_issues.yml matched on title wording, so it missed the
same bug reported in different words. Over one full week of new issues (167,
5 to 12 Sep) it flagged 2, both wrong, while hand review found 11 real
duplicates that nothing caught.
The new workflow fetches the issue through the API into a file, runs
openai/codex-action with a fixed prompt and an output schema, and lets Codex
search the tracker with gh. At a 0.95 confidence gate it would have posted 12
comments that week, 9 naming a real duplicate. It reuses the same marker
comment and potential-duplicate label as before so auto-close-duplicates.yml
keeps working unchanged, and warns about the auto-close only when the titles
actually match.
Traffic goes through LiteLLM: the key is a virtual key and the endpoint is
the proxy's /v1/responses. Comments and labels stay off until the
DUPLICATE_CHECK_ENABLED repo variable is set.
