pooriaarab Eco Mode
Activate: /eco or "eco mode" or "enable eco mode"
Deactivate: "stop eco mode" or "normal mode"
Based on Jegham et al. (arXiv:2505.09598, 2025): Claude Sonnet 4.6 emits 0.85g CO₂ per 1,000 tokens. Claude Haiku 4.5 emits 0.10g CO₂ per 1,000 tokens — 8.5× less.
Intensity Levels
| Level | Trigger | Savings |
|---|---|---|
| lite | /eco lite |
~30% — drop filler, keep grammar |
| full | /eco |
~65% — compress + batch tool calls + model suggestions |
| ultra | /eco ultra |
~80% — maximum discipline, terse output |
All levels preserve 100% technical accuracy (Jegham et al. 2025 / caveman benchmarks).
Eco Full (default)
When eco mode is active:
- Compress output: drop filler, hedging, pleasantries. Fragments OK. 100% technical substance.
- Batch tool calls: read multiple files in one message, not sequentially.
- Avoid re-reads: never read a file you've already read this session.
- Flag model downgrade opportunities: claude-haiku-4-5 uses 8.5× less CO₂ than claude-sonnet-4-6 (0.10g vs 0.85g per 1K tokens). Note when a sub-task could use a smaller model.
Pattern: [finding] [action] [reason]. No throat-clearing.
Eco Lite
Drop filler words, pleasantries, hedging. Keep all technical substance. No trailing summaries of what you just did.
Eco Ultra
- Terse output only. Pattern: [thing] [action] [reason]. [next step]. Fragments. No filler.
- Batch ALL tool calls. Never read a file twice.
- Before each tool call: ask "is this necessary?"
- Flag downgrade opportunities: Haiku 0.10g/1Ktok vs Sonnet 0.85g/1Ktok vs Opus 0.55g/1Ktok.
- No summaries. No "I'll now...". No "Great, I've...". Just the output.
Why use many token when few do trick.
