Backlog Analysis Toolkit

This directory contains a suite of AI-powered tools for analyzing GitHub issues and determining implementation effort levels for the Gemini CLI project.

📁 Directory Structure

data/: Contains the issue data in JSON and CSV formats.
- bugs.json: The primary source of truth for bug analysis.
utils/: Auxiliary scripts for manual overrides, debugging, and post-analysis validation (e.g., validate_effort.py, inject_manual_fixes.py).
*.py: Core analysis and export scripts (e.g., bug_analyzer_final.py, generate_bugs_csv.py).
loop_analyzer.sh: A shell script for running iterative analysis until all issues are processed.

📥 Prerequisites: Data Generation

Before running the analyzers, you must fetch the issue data from GitHub. The scripts expect the data in JSON format.

The easiest way to generate this is to simply copy the URL from your browser when looking at a filtered list of issues on GitHub, and pass it to our fetcher script.

(Note: You must have the GitHub CLI (gh) installed and authenticated).

# Fetch any filtered list of issues directly from a GitHub URL
python3 fetch_from_url.py "https://github.com/google-gemini/gemini-cli/issues/?q=type%3ABug+is%3Aopen" --output data/bugs.json

# Fetch features to a different file
python3 fetch_from_url.py "https://github.com/google-gemini/gemini-cli/issues/?q=type%3AFeature+is%3Aopen" --output data/issues.json

🚀 Workflows

1. Initial Triage (Static)

Use this for a quick, first-pass estimation.

python3 analyze_bugs.py --api-key "YOUR_KEY"

2. Deep Agentic Analysis

Uses Gemini as an agent with access to the codebase.

python3 bug_analyzer_final.py --api-key "YOUR_KEY"

3. Iterative Analysis

Runs the single-turn analyzer in a loop until all issues have a valid analysis.

GEMINI_API_KEY="YOUR_KEY" ./loop_analyzer.sh

4. Validation & Export

Run validation from the utils folder to ensure consistency, then generate a readable report.

python3 utils/validate_effort.py
python3 generate_bugs_csv.py

5. Generic Issue Processing

For any other backlog task (e.g., categorizing features, updating labels, or custom analysis), use the generic_processor.py. This script allows you to provide a custom system prompt and a project root for codebase context.

python3 generic_processor.py \
  --api-key "YOUR_KEY" \
  --input data/features.json \
  --output data/features_analyzed.json \
  --project ../../packages \
  --prompt "Analyze these features and suggest which package they belong in. Output JSON: {\"package\": \"name\"}"

🧠 Effort Level Criteria

Ratings are based on technical complexity and reproduction difficulty:

Small (1 day): Trivial logic changes, localized fixes (1-2 files), easy to reproduce.
Medium (2-3 days): Requires tracing across multiple components, UI state management (React/Ink), or harder reproduction.
Large (3+ days): Architectural issues, platform-specific (Windows, PTY, Signals), performance bottlenecks, or core protocol changes.

Note: Any bug that is difficult to reproduce or platform-specific must not be rated as Small.

🛠 Usage Notes

API Key: Ensure you have a valid Gemini API key set in the scripts.
Paths: Scripts are configured to look for data in the data/ subdirectory and the codebase in ../../packages.
Requirements: Requires Python 3 and jq (for the shell script).
