Token Saver

Reduce OpenClaw AI costs with model-aware optimization. Features dynamic compaction presets based on your model's context window, intelligent file compression, and robust model detection with fallback. Supports Claude, GPT-4, Gemini, DeepSeek, and more.

Token Saver v3

💡 Did you know? Every API call sends your workspace files (SOUL.md, USER.md, MEMORY.md, AGENTS.md, etc.) along with your message. These files count toward your context window, slowing responses and costing real money on every message.

Token Saver v3 is model-aware — it knows your model's context window and adapts recommendations accordingly. Using Gemini's 1M context? Presets scale up. On GPT-4o's 128K? Presets adjust down.

What's New in v3

Feature	v2	v3
Compaction presets	Fixed (80K/120K/160K)	Dynamic (% of model's context)
Model detection	Fragile, env-only	Robust fallback chain
Context windows	Not tracked	Full registry (9 models)
Model info	Hardcoded pricing	JSON registry, easy updates
Already-optimized	Re-compressed	Smart bypass

Commands

Command	What it does
/optimize	Full dashboard — files, models, context usage %
/optimize tokens	Compress workspace files (auto-backup)
/optimize compaction	Chat compaction control (model-aware)
/optimize compaction balanced	Apply balanced preset (60% of context)
/optimize compaction 120	Custom threshold (compact at 120K)
/optimize models	Detailed model audit with registry
/optimize revert	Restore backups, disable persistent mode

Features

📊 Model-Aware Dashboard

Shows current model, context window, and usage percentage:

🤖 Model: Claude Opus 4.5 (200K context)
   Detected: openclaw.json

📊 Context Usage: [████████░░░░░░░░░░░░] 42% (84K/200K)

📁 Workspace File Compression

Scans all .md files, shows token count and potential savings. Smart bypass skips already-optimized files.

File-aware compression:

• SOUL.md — Light compression, keeps personality language
• AGENTS.md — Medium compression, dense instructions
• USER.md / MEMORY.md — Heavy compression, key:value format
• PROJECTS.md — No compression (user structure preserved)

💬 Dynamic Compaction Presets

Presets adapt to your model's context window:

Preset	% of Context	Claude 200K	GPT-4o 128K	Gemini 1M
Aggressive	40%	80K	51K	400K
Balanced	60%	120K	77K	600K
Conservative	80%	160K	102K	800K
Off	95%	190K	122K	950K

🤖 Model Registry

24+ models with context windows, pricing, and aliases:

• Claude: Opus 4.6 (1M), Opus 4.5, Sonnet 4.5, Sonnet 4, Haiku 4.5, Haiku 3.5 (200K)
• OpenAI: GPT-5.2, GPT-5.1, GPT-5-mini, GPT-5-nano (256K), GPT-4.1, GPT-4o (128K), o1, o3, o4-mini
• Gemini: 3 Pro (2M), 2.5 Pro, 2.0 Flash (1M)
• Others: DeepSeek V3 (64K), Kimi K2.5 (128K), Llama 3.3 70B, Mistral Large

🔍 Robust Model Detection

Detection priority:

1. Runtime injection (--model=...)
2. Environment variables (SKILL_MODEL, OPENCLAW_MODEL)
3. Config file (~/.openclaw/openclaw.json)
4. File inference (TOOLS.md, MEMORY.md mentions)
5. Fallback: Claude Sonnet 4 (safe default)

Unknown model handling:

• Strict version matching — opus-6.5 won't fuzzy-match to opus-4.5
• Unknown models get safe defaults (200K context) + warning
• Easy to add new models to scripts/models.json

📝 Persistent Mode

Adds writing guidance to AGENTS.md for continued token efficiency:

File	Writing Style
SOUL.md	Evocative, personality-shaping
AGENTS.md	Dense instructions, symbols OK
USER.md	Key:value facts
MEMORY.md	Ultra-dense data

Safety

• Auto-backup — All modified files get .backup extension
• Integrity > Size — Never sacrifices meaning for smaller tokens
• Smart bypass — Skips already-optimized files
• Revert anytime — /optimize revert restores everything
• No external calls — All analysis runs locally
