Live Progress: a progress bar and ETA for Claude's long tasks

**English** | [简体中文](README.zh-CN.md)

  

When Claude works on a long task (research, batch file processing, a multi-section report), you usually can't tell how far along it is or how long it will take. **live-progress** is an [Agent Skill](https://github.com/anthropics/skills) that fixes that. At the start of a long task, Claude publishes a live progress page as an artifact. You can open it at any time to see:

• what Claude is doing right now
• every step, with its status and time taken
• a segmented progress bar, where each segment is sized by that step's estimated time
• time elapsed, time left, and the expected finish time
• a short activity log

How it works

Claude ──ArtifactData.update──▶ artifact database (run/state) ──live subscription──▶ progress page
        (once per checkpoint)                                                        (ticks every second)

• The page never writes anything. It subscribes to one document, run/state, in the artifact's database.
• Claude writes a small merge update at each checkpoint, usually when one step ends and the next begins. Only the changed fields are sent.
• The page does all the timing and ETA work itself, every second, from the timestamps Claude wrote.

How the ETA is estimated

1. Claude gives every step an estimate in minutes (est) when it plans the task.
2. The page learns a **p
