| name | code-review |
| description | Performs production-ready code reviews on git changes. Supports commit/range/file-scoped analysis, impact assessment, breaking-change detection, confidence-aware finding classification, and risk-weighted verdict generation. |
Code Review Capabilities
Structured capability set for reviewing git changes with evidence-backed findings and risk-aware verdicts.
Tools
- Git CLI: Retrieves commit metadata, diffs, range context, and history graph information
- Search tools (
rg, fd): Traces references, consumer impact, and related tests across repositories
Domains
- Change analysis: Diff interpretation, file classification, and change-scope characterization
- Impact assessment: Consumer tracing, publicly exposed contract impact, behavioral regression risk
- Risk evaluation: Severity classification, confidence modeling, and verdict generation
Input Contract
Review targets support three input shapes:
| Target Type | Required Fields | Description |
|---|
| Single Commit | commit_hash | Reviews one commit and its patch-level changes |
| Commit Range | start_hash, end_hash | Reviews a contiguous range where start_hash is earliest and end_hash is latest |
| File-Scoped | target (commit_hash or range) + file_path[] | Limits analysis to selected files within the target |
Preconditions
- Repository context is available and readable by git
- Target commit or range can be resolved from repository history
- Diff and metadata can be retrieved for the target
- If analysis preconditions fail (unknown hash, missing parent, ambiguous range), limitations are recorded in the review output
Core Capabilities
- Commit and Range Analysis: Collects metadata, patch details, and structural change information
- Change Classification: Categorizes files by role and change type for review prioritization
- Impact Detection: Traces direct and indirect consumers to estimate runtime and contract impact
- Breaking Change Detection: Identifies incompatible changes on externally consumable contracts
- Confidence-Aware Findings: Attaches evidence confidence and verification status to each finding
- Risk-Weighted Verdicts: Combines severity, confidence, and critical-domain context to determine outcome
Output Contract
Review output consists of:
- Findings: Each finding includes severity, evidence, impact, confidence, verification status, and remediation suggestion
- Verdict:
APPROVE, COMMENT, or REQUEST_CHANGES with explicit decision rationale
- Analysis Limitations: Unverifiable areas and constraints discovered during review
- Risk Context: Critical-domain exposure and weighted risk interpretation
Supported Analysis Types
- Commit Range: Review changes across a start~end commit range (start = earliest, end = latest)
- Single Commit: Review changes in a specific commit hash
- File-Scoped: Review specific files within a commit or range
Validation Scenarios
- Root Commit Review: Handles commits without parents via root-safe diff retrieval
- Merge Commit Review: Preserves first-parent and combined-merge perspectives for consistent interpretation
- Breaking Change + Consumer Counting: Uses normalized consumer counting to reduce false positives
- Dynamic/Reflective Usage: Reports unverifiable linkage with reduced confidence
- Behavior Coverage Risk: Escalates risk when changed behavior lacks relevant test coverage
- Verdict Reproducibility: Produces stable verdicts from deterministic weighted risk rules
Severity Levels
| Level | Scope |
|---|
| Critical | Security exposure, data integrity risk, service availability risk, externally breaking contract changes |
| Major | Behavioral defects, reliability degradation, significant performance or observability regressions |
| Minor | Maintainability, readability, and medium-term quality concerns |
| Nit | Low-impact consistency and polish suggestions |
