Claude-ETA Plugin Adds Task Timing and Repair Loop Detection to Claude Code

Claude-ETA is a Claude Code plugin that addresses inaccurate task time estimates and repetitive error loops in Claude AI. The tool was created after a developer observed Claude estimating a task would take "about 2 days" when it actually took 12 minutes to complete.

How It Works

The plugin runs silently in the background, timing every task and classifying it by type. It builds a local velocity profile specific to your project. After 10 tasks of the same type, it automatically injects calibrated ETAs at the start of Claude's responses.

Key Features

• Task Timing and Learning: Times every task, classifies tasks, and builds a local velocity profile based on your actual project performance
• Calibrated ETAs: After 10 tasks of the same type, ETAs appear automatically at the start of Claude's responses
• Repair Loop Detection: Detects when Claude hits the same error 3+ times and intervenes to force a strategy change
• Error Fingerprinting: Identifies errors based on content, not just count, so normal TDD (different errors each time) won't trigger intervention

Performance and Technical Details

An evaluation on 217 real completed tasks showed p80 coverage at 77.9%, meaning the real duration fell within the predicted upper bound about 78% of the time. The tool is 100% local with no cloud components, no telemetry, and no tracking. It's MIT licensed.

Installation

claude plugin marketplace add mmmprod/claude-eta
claude plugin install claude-eta

The entire tool was built using Claude Code. This is a solo developer's first open-source release.
