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:

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.
