chore(review): remove the custom Approvability check

[esthor]

Problem

The custom Approvability check in .coderabbit.config.ts runs as an error on outside contributors' pull requests. It fails when a maintainer should read a pull request, not when something is wrong, yet CodeRabbit then requests changes with "Pre-merge checks failed", even after every comment is resolved.

Change

Remove the check. CodeRabbit still requests changes while its comments are unresolved and approves once they are. The check can come back once "needs a maintainer's review" can be said without requesting changes.

Scope and approval

Focused configuration of the review setup from #16332: one pre-merge check removed, nothing else changed. I work at CodeRabbit.

Verification

Evaluated the config for each author association and for non-pull-request events: the only difference from main is the removed check, and each result passes CodeRabbit's schema. tsc, vp fmt --check, vp lint and knip pass. CodeRabbit reviews a fork pull request with the config at its recorded base commit, which ordinary pushes don't move. Outside pull requests opened after this merged (#17040, #17041) ran without the check and were approved. To run the updated config on an older pull request, rebase it onto main.

Approvability

Verdict: Approved at 7d11d8d

Macroscope's review found this PR approvable — This is a focused, one-file CodeRabbit configuration cleanup that changes automated review status handling but leaves the product, deployment, and existing comment-based gating behavior untouched. No product defaults or static-analysis suppressions are introduced.

📝 Walkthrough

Walkthrough

The configuration updates a comment about CodeRabbit’s handling of pull requests and removes the Approvability custom pre-merge check, including its pass/fail instructions.

Changes

Pull request review configuration

Layer / File(s)	Summary
Update review gating configuration .coderabbit.config.ts	The comment now refers to resolving comments and no longer states that checks must pass before approval. The Approvability custom pre-merge check and its pass/fail instructions were removed.

Priority: ⬇️ Low

Estimated code review effort: 1 (Trivial) | ~5 minutes

Change: Bug fix

Merge Risk: 🟡 Moderate · up to 7d11d

Outside contributors’ pull requests can lack the intended signal that a maintainer should review them. Restore Approvability in warning mode before merging, or explicitly accept that gap.

Architecture Summary

Architecture risk: 🔵 Low · up to 7d11d

The changed surface does not map to a changed system, dependency edge, entrypoint, or external dependency.

Changed systems: None identified.

No architecture-level concerns identified.

Review details

Before / after behavior

• observed — Modified behavior in .coderabbit.config.ts: The comment no longer says CodeRabbit waits for its checks to pass before approving others’ pull requests; it now refers only to resolving comments.
• observed — Modified behavior in .coderabbit.config.ts: The Approvability custom check was removed from pre_merge_checks, including its gated error/off mode and the approvability instructions that defined its pass/fail rules.

Full details: Approvability

Explanation

The pull request needs a maintainer's review. It changes the review tool configuration in .coderabbit.config.ts: it removes the Approvability custom check and changes the approval comment. This matches the explicit rule for changing any review tool configuration.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Keep Approvability configured as a warning for gated authors.

The head removes the only Approvability custom check. A gated pull request that triggers an Approvability rule can therefore receive no maintainer-review signal when no other review comment is produced. Restore the check and use warning instead of error.

Suggested fix

 import { defineConfig, type CodeRabbitContext } from "@coderabbitai/config";
 
+const approvability = `Fail when a maintainer should read this pull request before CodeRabbit approves it, and name the rule and file. Fail if it:
+
+- Changes a product default: a setting's default value, or what users get without opting in. Making a feature do what it already promises is a bug fix, not a default change.
+- Adds or broadens a directive that disables or suppresses a lint, type-checker, LSP, or other static-analysis diagnostic, including file-level, line-level, and configuration-level overrides.
+- Adds a subsystem or user workflow, or is a large refactor across apps or packages.
+- Changes packages/contracts or persisted data in a way that existing clients or stored data might not accept.
+- Changes authentication, pairing, credentials, secrets, or remote connection trust.
+- Adds or changes an external side effect, such as acting on GitHub, publishing a release, or calling a webhook.
+- Adds, upgrades, or patches a dependency.
+- Changes CI or release configuration, agent or contributor instructions, or any review tool's configuration, including .github/, AGENTS.md, CONTRIBUTING.md, .agents/, and .coderabbit.config.ts.
+
+Otherwise pass. A focused bug fix, copy or layout fix, revert, or docs-only or test-only change passes unless a rule above applies. If you cannot decide, fail rather than report inconclusive. When failing, say that the pull request needs a maintainer's review.
+`;

 // Org members and collaborators merge their own pull requests. On anyone else's, CodeRabbit

@coderabbitai Intentional. As a warning, the check would still show contributors a "needs a maintainer's review" item they can't act on. It can come back once that can be said without requesting changes.

Tip

For best results, initiate chat on the files or code changes.

@esthor Thanks for clarifying. Removing Approvability avoids giving contributors a maintainer-review item they cannot resolve. I withdraw my concern about removing the check.

Learning: In pingdotgg/t3code, removal of the `Approvability` custom pre-merge check from `.coderabbit.config.ts` is intentional. A warning would still show outside contributors a "needs a maintainer's review" item they cannot act on. The check should return only when it can communicate that need without requesting changes.
