cubic adapts review to a team’s codebase
cubic describes codebase and cross-repository review, team-specific rules, and coding agents that can fix issues. Its review documentation covers custom agents and access to library and framework documentation.
That context is relevant when a warning depends on a convention elsewhere in the codebase. Check which rules were learned and whether reviewers can correct an unhelpful one.

Documented workflows and the evidence to inspect. Custom tools and configuration can change what a review can access.

| Compare | cubic | Proofline |
|---|---|---|
| Context | Codebase and cross-repository analysis, review rules, and supporting documentation. | Pinned code input and the selected environment’s recorded infrastructure snapshot. |
| Automation | Review feedback and agent-assisted code fixes. | Advisory findings by default, with separately configured deterministic gates. |
| Feedback to inspect | Whether learned rules reflect the standards your team wants to enforce. | Whether the cited infrastructure facts support the claimed failure for this deployment. |
How Proofline investigates changes explains its code and environment inputs. Check connector coverage before assuming that an assessment can observe a resource.
A shared client doubles its connection pool
Suppose a shared library changes its default pool size. Several services inherit the new value without changing their own configuration files.
Tracing that default across repositories is part of the investigation. Assessing its deployment consequence also requires the services’ replica counts and the database’s connection limit. The aggregate demand may matter even if each service is reasonable on its own.
Use this illustrative case to inspect both dependency tracing and resource attribution. Check which services the result includes and whether their configuration belongs to the same target environment.
Check team rules and infrastructure attribution
Choose cubic when its review rules and code-fix workflow suit your GitHub team. Evaluate Proofline when a finding must account for shared infrastructure and the resources deployed against it.
A useful trial includes a change that crosses a repository boundary. Compare the evidence linking each consumer to the changed behavior, then check how the assessment establishes the deployment configuration.
Questions about cubic and Proofline
Is cubic limited to changed lines?
No. Its published capabilities include codebase and cross-repository analysis. Compare the configured scope rather than assuming that it sees only a diff.
Can Proofline infer database demand from pool size alone?
No. Pool size is one input. A supported deployment finding also needs the relevant workload and database evidence, with missing information made visible.

Connect a GitHub repository and its deployment environment, then inspect the evidence behind the findings. Missing evidence stays visible; a review without findings does not establish deployment success.
