 # object_reference — Claude Code instructions
 
-## Monitor GitHub CI after every push
-
-This repository runs GitHub Actions CI (`.github/workflows/ci.yml`) on every push
-and pull request. After **every** `git push` to this repo — whether to a branch or
-one that updates an open PR — monitor the resulting CI run to completion and fix any
-failures before treating the work as done:
-
-1. Find the run: `gh run list --branch <branch> --limit 1`
-2. Watch it: `gh run watch <run-id>` (or poll `gh run view <run-id>`)
-3. On failure: `gh run view <run-id> --log-failed`, diagnose, fix, and push again.
-
-Do not consider a push complete until its CI run is green (or the failure is
-understood and explicitly accepted by the user).
-
-## PR title convention for CI-only PRs
-
-A PR gets a title starting with `CI: ` (capital, colon, space) when its diff
-doesn't touch anything involved with the actual code itself — this is a HARD
-boundary, not a synonym for "lives under `.github/workflows/`":
-
-- If a change touches ANYTHING that's part of the actual code — SQL source,
-  `object_reference.control`, anything that affects what gets installed or
-  how it behaves at runtime — it is NOT CI-only, full stop. When unsure,
-  **always err on the side of NOT CI-only.**
-- Files elsewhere that genuinely don't touch the code qualify too, not just
-  `.github/workflows/*`: e.g. `.gitignore`, this `CLAUDE.md`, other pure
-  documentation/metadata.
-- **`test/` is treated as NOT CI-only, even though it's a bit of a grey
-  area.** Test files aren't the shipped code itself, but default to
-  excluding them from the prefix rather than trying to judge case by case.
-- A PR that's CI-*motivated* but also touches a real code/test file (a
-  `bin/` script a workflow calls, a linter's `Makefile` wiring if it affects
-  what ships, a submodule) is NOT CI-only under this reading, even though CI
-  is the reason it exists — don't stretch the prefix to cover those.
-
-Check the actual file list
-(`gh pr view <n> --json files --jq '.files[].path'`) before applying it, don't
-guess from the title/description alone.
