# CodeRabbit Review Performance Tuning

## Overview

Optimize operator-controlled inputs and measure effects. Separate service latency, provider delay, limits, diff size, paths, tools, and guidance.

## Prerequisites

- Identify the CodeRabbit organization, Git provider, repository, plan, and accountable owner.
- Read `references/official-docs.md` and re-check any time-sensitive contract before execution.
- Use synthetic or read-only evidence until the approval boundary is satisfied.
- Preserve the repository's independent CI, security, and human-review requirements.

## Current Contract

- Path filters change scope; path instructions change guidance.
- Incremental reviews can pause after configured reviewed commits.
- Caching normally accelerates review but can be disabled.
- Plan limits belong to the live plans contract.

## Authentication

Treat Git-provider sessions, CodeRabbit web sessions, CLI credentials, and CodeRabbit API keys as separate credentials. Use only an already-approved session or secret-manager reference, never print a secret, and do not place credentials in `.coderabbit.yaml`, source files, logs, or deliverables.

## Instructions

1. Capture events, files, diff size, tools, cache, limits, findings, and timing.

2. Classify delay or noise by boundary.

3. Pilot one scope, filter, instruction, profile, or incremental-review change.

4. Compare equivalent samples and roll back hidden-risk regressions.

## Tool Discipline

- Use **Glob** to locate candidate configuration and evidence files without widening scope.
- Use **Grep** to find relevant fields, commands, identifiers, and stale claims.
- Use **Read** to inspect the smallest required files and authoritative evidence.
- Use **Write** only for a new approved local draft or evidence artifact.
- Use **Edit** only for a bounded approved change whose rollback is known.
- Do not use these file tools as a substitute for authenticated CodeRabbit or provider operations.

## Approval Boundaries

Require security or code-owner approval before exclusions, tool disablement, or shared changes. Keep analysis and drafts local until approval is explicit, and record who approved the action and its scope.

## Output

A baseline, hypothesis, patch, comparison, risk check, and keep-or-rollback decision. Include source dates, unknowns, and the exact boundary between observed fact and recommendation.

## Error Handling

| Condition | Response |
|---|---|
| Current contract is unclear or docs disagree | Stop mutation, cite both sources, and request owner resolution. |
| Required access or approval is missing | Produce a draft and evidence plan only. |
| Validation or pilot behavior differs from expectation | Restore the prior state and retain the failed evidence. |
| Output contains secrets or private code | Stop, quarantine the artifact, redact it, and notify the data owner. |

## Examples

### Example 1

Exclude generated artifacts while retaining sensitive code.

### Example 2

Tune incremental-review pause for a high-churn branch.

## Validation

- Confirm every claim against the dated sources in `references/official-docs.md`.
- Verify the requested scope, owner, approval, happy path, failure path, and rollback.
- Re-read the effective configuration or provider state after any approved change.
- Report unsupported fields, undocumented endpoints, and unverified assumptions as failures.

## Resources

- [Official documentation and contract notes](references/official-docs.md)
- Re-check the dated contract before any live operation.
- Treat unresolved or changed vendor behavior as a stop condition.
