Your context window as a stacked bar above the prompt, a color per category, with token counts and the compaction point. /context-bar shows or hides it.
Token Weather
See how full Claude Code's context window is
A one-line forecast above the prompt shows how full the context window is, as a weather icon, a percentage, tokens used out of the window and a chart of recent turns.
What this mod can do
- Reviewed at commit 569c528
Good to know (3)
- It measures the full window, so it can read lower than Claude Code's notice, which counts to auto-compact.
- Updates once per turn, not during one, and reads 0% until the first response reports usage.
- Another plugin that draws above the prompt competes for the same band.

How it works
- Takes a first reading when the session starts
- After each main-loop turn, reads context tokens and window size (subagent turns skipped)
- Picks a forecast from the share used, from ☀ Clear under 25% to ↯ Compact soon at 90%
- Draws the band with a chart of the last 12 turns and what the last turn added
Common questions
How do I check how much of the context window Claude Code has used?
Token Weather shows it above the prompt after every turn: the percentage used, the tokens used out of the window and a weather word for the level. It reads the same figures the status line gets (total_input_tokens, context_window_size, used_percentage).
Why is its percentage different from Claude Code's context notice?
The band measures against the full context window, while Claude Code's notice counts toward the auto-compact point, which is lower. In the author's test the band read 81% when the notice read 90%.
What do the weather icons mean?
☀ Clear under 25% used, ☁ Cloudy from 25%, ☂ Showers from 50%, ☇ Storm from 75% and ↯ Compact soon from 90%.
