SUMMARY

Local AI code review assistant built on dspy-go.

Maestro - Advanced AI-Powered Code Review Assistant

Maestro is an AI code review and repository analysis assistant built on top of dspy-go. It is no longer just a one-shot PR review CLI: the repo now includes a live review path, a repository ask path with RLM-backed long-context support, benchmark-driven optimization commands, and a staged self-evolution loop for reviewer improvement.

🎯 Core Features

Advanced Context Analysis

  • Chunked Review Pipeline: Maestro reviews changed code in chunked passes with line-grounded findings.
  • Guideline Integration: review runs can use cached guidelines and repository-aware context.
  • Artifact-Aware Runtime: live review runs can load tuned review artifacts and persisted skill stores.
  • Repository Ask Support: Maestro can answer codebase questions in addition to reviewing PRs.

Intelligent Review Pipeline

  • Specialized PR Review Agent: Maestro uses a dedicated Go review path rather than a generic chat wrapper.
  • Parallel Review Execution: chunk evaluation runs concurrently for throughput on larger PRs.
  • Review Filtering and Verification: the review path includes post-processing to suppress weak or off-target comments.
  • Benchmark-Driven Optimization: the review benchmark and evaluator can drive GEPA tuning offline.

GitHub Integration

  • Direct PR Review: review GitHub pull requests from the CLI or TUI.
  • Existing Comment Awareness: Maestro processes prior PR comment context during review runs.
  • Token Verification: the root CLI verifies GitHub permissions before operating.

Terminal UI (TUI v2)

  • Interactive Mode: the root command still launches the modern interactive interface when no PR is provided.
  • Slash-Command Workflow: Maestro supports review and ask-style interaction patterns.
  • Shared Runtime Wiring: the same service layer backs both direct CLI review and interactive usage.

Semantic Code Search (Sgrep)

  • Search Tooling: Maestro has an sgrep-backed search path and test coverage around its runtime environment wiring.
  • Guideline / Context Lookup: the review engine can incorporate indexed repository guidance.
  • RLM Companion Role: semantic lookup complements the long-context overview lane.

Unified Agent Architecture

  • Single Root CLI: main.go is still the normal entry point.
  • Live Review + Ask + Offline Tuning: Maestro now spans serving and offline learning in one repo.
  • Persisted Reviewer Consumption: the live review path can load a reviewer produced by optimize-review or evolve-review.

Flexible Model Support

  • dspy-go Model Abstraction: Maestro uses the same provider/model abstraction layer as dspy-go.
  • Primary + Teacher Model Support: optimization commands support separate student and teacher models.
  • Deterministic Eval Support: the evolution lane can force evaluation temperature to 0 for stability.

🛠️ Enhanced Technical Capabilities

Review Dimensions

  • Correctness-first Review: Maestro is currently tuned toward concrete, actionable Go findings.
  • Behavior / API Regression Awareness: the current review seed explicitly includes API contract and behavior regressions.
  • Negative-case Suppression: the benchmark/evaluator penalizes low-value or noisy comments.

Advanced Features

  • Persisted Optimized Programs: review and QA optimization now use the dspy-go.optimized-agent-program envelope.
  • Forward-Compatible Restore: obsolete target IDs in saved optimized programs are skipped on restore.
  • Staged Self-Evolution: evolve-review separates cheaper GEPA search from full replay validation.
  • Promotion Gates: main replay regression tolerance and protected-suite regression tolerance are both supported.
  • Retention + Circuit Breaker: the evolution runner can prune historical runs and stop after repeated failures.

📦 Getting Started

Prerequisites

  • Go 1.24+
  • GitHub token with PR access
  • a supported model backend configured through dspy-go

Installation

git clone https://github.com/XiaoConstantine/maestro.git
cd maestro
go mod download
go build ./...

Local Model Setup (Optional)

Maestro still supports local or custom model endpoints through the shared dspy-go provider layer. For example, local OpenAI-compatible endpoints can be used through --model, --provider, and --base-url.

Quick Start

# Launch interactive mode
go run .

# Review a PR directly
go run . \
  --owner XiaoConstantine \
  --repo dspy-go \
  --pr 291 \
  --model google:gemini-2.5-flash

# Review with a tuned reviewer
go run . \
  --owner XiaoConstantine \
  --repo dspy-go \
  --pr 291 \
  --model google:gemini-2.5-flash \
  --review-artifacts ~/.maestro/evolution/review/rsc/current/optimized_program.json \
  --review-skill-store ~/.maestro/evolution/review/rsc/skills.json

Sgrep / Local Embeddings

Maestro still supports local search/indexing flows, and the repo includes sgrep-related tests and review engine integration. Exact provider wiring depends on your local environment and dspy-go model configuration.

Feature Toggles

The repo still contains ACE and RLM-related runtime wiring, but the most important operational knobs now live in the review/evolution commands themselves rather than only in environment flags.

Command Line Options

  • Root CLI:

    • --owner
    • --repo
    • --pr
    • --model
    • --github-token
    • --review-artifacts
    • --review-skill-store
    • --review-skill-domain

  • cmd/optimize-review:

    • --suite
    • --artifact
    • --teacher-model
    • --population
    • --generations
    • --validation-frequency
    • --max-metric-calls
    • --max-runtime

  • cmd/evolve-review:

    • --state-dir
    • --suite
    • --search-suite
    • --protected-suite
    • --regression-tolerance
    • --protected-regression-tolerance
    • --max-runtime

Model Selection

# Gemini
go run . --model google:gemini-2.5-flash --owner XiaoConstantine --repo dspy-go --pr 291

# OpenAI-compatible local endpoint
go run . --model openai:Qwen3.5-9B-OptiQ-4bit --base-url http://127.0.0.1:8081 --owner XiaoConstantine --repo dspy-go --pr 291

# Optimize review with a separate teacher model
go run ./cmd/optimize-review \
  --suite ~/.maestro/review/corpora/rsc-golang-org/review_go_suite.json \
  --model google:gemini-2.5-flash \
  --teacher-model google:gemini-2.5-pro

📊 Performance & Metrics

Current Scale

  • Live Review: operational on real PRs through the root CLI.
  • Offline Optimization: review and QA optimization commands now persist optimized programs.
  • Evolution Runner: the staged evolve-review loop can now complete end to end and publish a reviewer.

Recent Improvements

  • Optimized-program restore: Maestro consumes the newer dspy-go optimized-program envelope.
  • Structured RLM replay alignment: the RLM overview lane is aligned with the newer adaptive replay / sub-RLM controls.
  • Deterministic evaluation: evolution runs can set evaluation temperature to 0.
  • Staged search: GEPA breadth is no longer forced to collapse just to keep full replay affordable.
  • Protected gating: protected-suite replay is deferred and gated separately from the main lane.

🔬 Advanced Usage

Debug Mode

go run . \
  --owner XiaoConstantine \
  --repo dspy-go \
  --pr 291 \
  --model google:gemini-2.5-flash \
  --verbose

Performance Tuning

# One-off benchmark optimization
go run ./cmd/optimize-review \
  --suite ~/.maestro/review/corpora/rsc-golang-org/review_go_suite.json \
  --population 4 \
  --generations 2 \
  --max-metric-calls 20

# Staged self-evolution
go run ./cmd/evolve-review \
  --state-dir ~/.maestro/evolution/review/rsc \
  --search-suite ~/.maestro/review/corpora/rsc-golang-org/review_go_train_70_30.json \
  --suite ~/.maestro/review/corpora/rsc-golang-org/review_go_suite.json \
  --protected-suite ~/.maestro/review/corpora/mdempsky-google-com/review_go_suite.json \
  --eval-temperature 0 \
  --regression-tolerance 0.015 \
  --protected-regression-tolerance 0.04 \
  --population 8 \
  --generations 4

Current Caveats

  • The self-evolution control plane works.
  • Review-quality gains are still corpus-sensitive.
  • The first successful promotion proved the pipeline, not final reviewer quality.
  • Benchmark wins and live PR-review wins are related, but not interchangeable.
