Token Saver is Power Claude’s context optimizer: it trims low-signal noise from what the model re-reads (shell dumps, logs, diffs, JSON whitespace) so more of each turn is real work — not repeated tool spam.
TL;DR
| Item | Detail |
|---|---|
| Goal | Fewer tokens per turn on repetitive tool output |
| Default | On (standard profile) |
| Knobs | Level / profile + per-type toggles (command, log, diff, json) |
| Measure | Usage tab · Token Tree · cost analytics |
| Not | A free Max upgrade or rate-limit bypass |
What it actually optimizes
| Channel | Typical effect |
|---|---|
| Command output | Collapse huge ls / build / test dumps |
| Logs | Drop heartbeats; keep errors/warnings |
| Diffs | Keep changed lines; trim unchanged context |
| JSON | Lossless whitespace minify |
You keep semantics that matter for coding; you lose bulk that only re-inflates the window.
How to set it
- Command: Power Claude: Token Saver (slider) or Settings →
tokenSaver/contextOptimize. - Start at standard / mid level.
- If answers get worse on huge refactors, step down to conservative.
- If you live in CI logs, keep log+command on.
- Pair with Warm Compacting so when you do near the wall, you don’t stall.
Prove it on your machine
- Open dashboard → Usage.
- Compare sessions with Token Saver on vs off (same task shape).
- Open Token Tree for a hot session — see which tools dominate.
- Savings shown locally are your numbers, not a brochure claim.
FAQ
Does it change my Anthropic bill formula?
It reduces tokens the model consumes in context. Plan limits and pricing still follow Anthropic. Power Claude’s subscription is separate.
Can it drop an error line I needed?
Log/command optimizers are designed to preserve errors/warnings; still verify on critical forensic sessions (turn level down).
