Glimpse: AI-Powered Micro-Reviewer

Glimpse is a lightweight, local daemon that watches your active repository. When you stage your changes the git diff is captured and fed to an LLM, and which it will provide a concise engineering review to stdout.

It is designed for "Vibecoding"—maintaining flow state while getting instant feedback on correctness.

🚀 Installation

Go Install (Recommended)

go install github.com/revrost/glimpse@latest

This installs glimpse to your GOPATH/bin (usually ~/go/bin/). Make sure ~/go/bin is in your PATH.

Features

• Git diff capture for staged and unstaged changes
• Focused reviews for bugs, performance, and security issues
• Nice stdout interface

Quick Start

1. Configure API Key

   export OPENAI_API_KEY="your-api-key-here"
   # or for Gemini
   export GEMINI_API_KEY="your-gemini-key-here"
   # or for Z.AI
   export ZAI_API_KEY="your-zai-key-here"
   # or for CLAUDE
   export CLAUDE_API_KEY="your-claude-key-here"

2. Create Configuration (.glimpse.yaml in repo root)

   watch:
     - "./internal/**/*.go"
     - "./pkg/**/*.go"
   ignore:
     - "*_test.go"
   logs:
     file: "./tmp/server.log"
     lines: 50
   llm:
     provider: "openai"
     model: "gpt-4o"
     system_prompt: "You are a Principal Go Engineer. Review strictly for bugs, perf, and slog context."

3. Start Glimpse

   glimpse
   # or if using local build:
   ./glimpse

Managing Your Installation

Update to Latest Version

go install github.com/revrost/glimpse@latest

Check Version

glimpse -version

Uninstall

rm $(which glimpse)

Configuration

Glimpse uses a .glimpse.yaml file in the repository root. If not found, it uses sensible defaults.

Watch Configuration

watch:
  - "./internal/**/*.go"    # Watch Go files in internal directory
  - "./pkg/**/*.go"         # Watch Go files in pkg directory
  - "./src/**/*.rs"         # Watch Rust files
ignore:
  - "*_test.go"             # Ignore test files
  - "*.generated.go"         # Ignore generated files
  - "vendor/**"             # Ignore vendor directory

Log Configuration

logs:
  file: "./tmp/server.log"   # Log file to tail
  lines: 50                 # Number of recent lines to include

LLM Configuration

llm:
  provider: "openai"         # openai, gemini, ollama, zai
  model: "gpt-4o"          # Model to use
  api_key: "optional-key"    # Can use env vars instead
  system_prompt: "You are a Principal Go Engineer. Review for bugs, performance, and security."

API Keys

API keys can be provided via:

1. Environment variables: OPENAI_API_KEY, GEMINI_API_KEY, ZAI_API_KEY, CLAUDE_API_KEY
2. Configuration file: api_key field in llm section

Context Window Strategy

Glimpse sends a structured prompt to the LLM:

SYSTEM: [System Prompt]

CONTEXT:
1. File: internal/handlers/payment.go
2. Git Diff:
   [Output of git diff --unified=0 internal/handlers/payment.go]

3. Recent Runtime Logs (tail -n 50):
   [Raw content of server.log]

TASK:
Review the diff. If the logs show errors related to this logic, highlight them immediately.
Be concise.
