🧭 Context

We've had CodeRabbit enabled for most of the lifetime of this project, but we haven't really adjusted its knobs. There are opportunities to get more value and less noise out of it.

See https://docs.coderabbit.ai/reference/configuration.

📚 Description

• tweak various options to decrease noise and increase signal
• enable every relevant security tool
• experimentally turn on slop detection (this just labels PRs with the label 007 if it flags it as slop)
• switch to UK English as the team is majority European 😁

Warning

Ignoring CodeRabbit configuration file changes. For security, only the configuration from the base branch is applied for open source repositories.

📝 Walkthrough

Walkthrough

A new .coderabbit.yaml configuration file was added to set CodeRabbit's behaviour and preferences. The configuration specifies the assistant language as en-GB and configures PR review settings, including review status, changed-files summaries, sequence diagrams, and linked-issue assessment. It enables slop detection, defines auto-review pause thresholds, and specifies patterns and usernames to ignore during reviews. Pre-merge checks are configured with per-check modes for docstrings, titles, descriptions, and issue assessment. The configuration enables specific automated analysis tools (gitleaks, osvScanner, actionlint, yamllint, shellcheck, dotenvLint) whilst disabling others that are redundant or not suitable for the repository.

🚥 Pre-merge checks | ✅ 1

✅ Passed checks (1 passed)

Check name	Status	Explanation
Description check	✅ Passed	The PR description clearly relates to the changeset, explaining the rationale for configuring CodeRabbit to reduce noise and increase signal.

_{✏️ Tip: You can configure your own custom pre-merge checks in the settings.}
