CodeRabbit Semgrep config file auto-discovery behavior documentation

💡 Result:

CodeRabbit's Semgrep config file auto-discovery behavior is documented in the official docs at https://docs.coderabbit.ai/tools/semgrep. By default, CodeRabbit automatically uses Semgrep config files named semgrep.yml, semgrep.yaml, semgrep.config.yml, or semgrep.config.yaml if present in the root directory of the repository. Semgrep only runs if a config file is found using these default names, or if a custom path is explicitly specified via: - reviews.tools.semgrep.config_file in the repository's .coderabbit.yaml file, or - The "Reviews → Tools → Semgrep → Config File" field in CodeRabbit's web settings UI. Due to licensing restrictions, CodeRabbit does not include community Semgrep rules and requires a user-provided config with rules. Note that the related OpenGrep tool (Semgrep-compatible) has a broader fallback search order including Semgrep files, starting from repo root and PR-changed files, then broader search—but Semgrep itself sticks to root defaults or explicit paths.

Citations:

Add config_file: .semgrep.yaml to enable Semgrep with repository-owned rules.

CodeRabbit auto-discovers only semgrep.yml, semgrep.yaml, semgrep.config.yml, and semgrep.config.yaml. This repository uses .semgrep.yaml, which falls outside the auto-discovery pattern. Setting enabled: true alone will not load your repository-owned rules. Explicitly specify the config file path to enable Semgrep properly.

Suggested fix 
     semgrep:
       enabled: true
+      config_file: .semgrep.yaml

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

In @.coderabbit.yml around lines 109 - 112, Add the repository-owned Semgrep
config path under the existing semgrep section so CodeRabbit loads
.semgrep.yaml: in the .coderabbit.yml semgrep block (the keys "semgrep" and
"enabled") add a "config_file: .semgrep.yaml" entry alongside enabled: true to
explicitly point CodeRabbit to the repository's Semgrep rules file.
