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.

OpenClaw Skill Lazy Loader

Stop loading every skill file at session start. 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:

# 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:

# 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:

## 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:

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:

## 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

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. 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:

clawhub install openclaw-skill-lazy-loader
clawhub install openclaw-token-optimizer

Files in This Skill

Quick Start (5 minutes)

# 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"
