ci: make blink ci failure prompt a gha variable (#19633)

ethanndickson · web-flow · commit 98c72c3a2585 · 2025-09-02T11:07:24.000+10:00
Got sick of seeing blink create duplicates, so I'm updating the prompt. To make it configurable without committing I'm making it a variable, here's what I've got:

&gt; Investigate this CI failure. Check logs, and figure out what went wrong. Search for existing issues in coder/internal. If an issue for the CI failure does not exist already, create one ONLY in coder/internal. Do NOT create duplicate issues. Use title format \"flake: TestName\" for flaky tests, and assign them to the person from git blame.
If multiple tests fail with the reason `unknown`, the test process exited unexpectedly, perhaps due to a panic.

Once blink supports per-slack-channel contexts, i'll probably just set the variable to the empty string and use that instead.
