# Openclaw Skill Lazy Loader > This skill pairs directly with [OpenClaw Token Optimizer](https://clawhub.ai/Asif2BD/openclaw-token-optimizer). Lazy loading handles **context loading costs**; Token Optimizer handles **model routing, heartbeat budgeting, and runtime costs**. Together they cover the full token lifecycle. Use when this capability is needed. - Skill: `tomevault-io/openclaw-skill-lazy-loader` (Agent Skill, multi-file: 2 files) - Install (CLI): `npx skillmds@latest add tomevault-io/openclaw-skill-lazy-loader` - Raw SKILL.md: https://api.skillmd.com/api/skills/tomevault-io/openclaw-skill-lazy-loader/raw - Safety review: pending (external: skill-scanner PASS, skillspector WARNING) - Works with: Claude Code, Claude.ai, OpenAI Codex - Category: AI & ML - Author: tomevault-io (https://skillmd.com/u/tomevault-io) - Updated: 2026-09-17 - Page: https://skillmd.com/skills/tomevault-io/openclaw-skill-lazy-loader --- --- name: openclaw-skill-lazy-loader description: Dramatically reduce per-session token usage by loading skills and context files only when needed — not at session start. Includes the SKILLS catalog pattern, AGENTS.md lazy loading strategy, and a Python helper that recommends exactly which files to load for any given task. Compatible with all OpenClaw agents.

Load what you need, when you need it — and cut your token usage by 40–70%. ## The Problem Most OpenClaw agents load their entire skill library at startup: ```markdown # AGENTS.md (naive approach) Read ALL of these before starting: - skills/python/SKILL.md - skills/git/SKILL.md - skills/docker/SKILL.md - skills/aws/SKILL.md - skills/browser/SKILL.md ... (20 more) ``` Each session burns **3,000–15,000 tokens** just loading context that may never be used. At scale, this is your biggest cost. ## The Solution: Lazy Loading Instead of loading skills upfront, agents check a **SKILLS catalog** (a lightweight index) and load individual skill files only when a task requires them. **Before:** Load 20 skill files = ~12,000 tokens/session **After:** Load catalog (300 tokens) + 1–2 relevant skills (~800 tokens) = **~1,100 tokens/session** That's an **89% reduction** on context loading alone. --- ## Implementation Guide ### Step 1: Create Your SKILLS Catalog Create `SKILLS.md` in your agent workspace — a lightweight index of all available skills: ```markdown # Available Skills | Skill | File | Use When | |-------|------|----------| | Python | skills/python/SKILL.md | Writing/debugging Python code | | Git | skills/git/SKILL.md | Git operations, PRs, branches | | Docker | skills/docker/SKILL.md | Containers, images, compose | | Browser | skills/browser/SKILL.md | Web scraping, UI automation | | AWS | skills/aws/SKILL.md | Cloud deployments, S3, Lambda | ``` This catalog is the ONLY file loaded at session start. ~200–400 tokens instead of 10,000+. See `SKILLS.md.template` for a complete starter template. ### Step 2: Update Your AGENTS.md Replace bulk loading with the catalog pattern: ```markdown ## Skills At session start: Read SKILLS.md (the index only). When a task needs a skill: Read the specific SKILL.md for that skill. Never load all skills upfront. ### Loading Decision Before loading any skill file: 1. Does the current task need it? (yes → load it, no → skip) 2. Has it already been loaded this session? (yes → skip, no → load once) ``` See `AGENTS.md.template` for the full recommended AGENTS.md skills section. ### Step 3: Use the Context Optimizer (Optional) The included `context_optimizer.py` analyzes your task description and recommends which skills to load: ```bash python3 context_optimizer.py recommend "Write a Python script to push to S3" # Output: # Recommended skills to load: # - skills/python/SKILL.md (confidence: high — Python task) # - skills/aws/SKILL.md (confidence: high — S3 mentioned) # - skills/git/SKILL.md (confidence: low — skip unless pushing to GitHub) ``` ### Step 4: Apply to Memory Files Too The same pattern works for memory and context files: ```markdown ## Memory Loading (AGENTS.md) At session start: Read MEMORY.md (summary only). Load daily files (memory/YYYY-MM-DD.md) only when: - User asks about past work - Task references a specific date or project - Debugging requires historical context ``` --- ## Token Savings Calculator | Scenario | Before | After | Savings | |----------|--------|-------|---------| | 5 skills loaded | ~3,000 tokens | ~600 tokens | 80% | | 10 skills loaded | ~6,500 tokens | ~750 tokens | 88% | | 20 skills loaded | ~13,000 tokens | ~900 tokens | 93% | | +Memory files (5) | +4,000 tokens | +400 tokens | 90% | *Estimates based on average SKILL.md size of ~600 tokens. Catalog averages ~150 tokens.* --- ## Integration with Token Optimizer This skill pairs directly with [OpenClaw Token Optimizer](https://clawhub.ai/Asif2BD/openclaw-token-optimizer). Lazy loading handles **context loading costs**; Token Optimizer handles **model routing, heartbeat budgeting, and runtime costs**. Together they cover the full token lifecycle. Install both: ```bash clawhub install openclaw-skill-lazy-loader clawhub install openclaw-token-optimizer ``` --- ## Files in This Skill | File | Purpose | |------|---------| | `SKILL.md` | This guide | | `SKILLS.md.template` | Starter SKILLS catalog template | | `AGENTS.md.template` | Lazy loading AGENTS.md section | | `context_optimizer.py` | CLI helper — recommends skills to load per task | | `README.md` | ClawHub listing description | | `SECURITY.md` | Security audit and script disclosure | | `.clawhubsafe` | File integrity manifest | --- ## Quick Start (5 minutes) ```bash # 1. Install clawhub install openclaw-skill-lazy-loader # 2. Copy templates to your agent workspace cp ~/.openclaw/skills/openclaw-skill-lazy-loader/SKILLS.md.template ~/my-agent/SKILLS.md cp ~/.openclaw/skills/openclaw-skill-lazy-loader/AGENTS.md.template ~/my-agent/AGENTS.lazy.md # 3. Edit SKILLS.md — fill in your actual skills # 4. Merge AGENTS.lazy.md into your AGENTS.md # 5. Test with context_optimizer.py python3 ~/.openclaw/skills/openclaw-skill-lazy-loader/context_optimizer.py recommend "your next task" ``` --- *By M Asif Rahman (@Asif2BD) · Apache 2.0 · https://clawhub.ai/Asif2BD/openclaw-skill-lazy-loader* --- > Source: [modbender/skill-library-mcp](https://github.com/modbender/skill-library-mcp) — distributed by [TomeVault](https://tomevault.io).
