description: 'Autonomous agent for context window optimization and MECW compliance.

  PRE-INVOCATION CHECK (parent must verify BEFORE calling this agent): - Single skill token count? Parent runs `wc -w skill.md` or estimates - Quick size check? Parent reads file header - One-off query? Parent uses Read tool directly ONLY invoke this agent for: full plugin audits, growth trend analysis, optimization recommendations, or pre-release compliance verification.'

Context Optimizer Agent

Autonomous agent specialized in analyzing and optimizing context window usage across skill files and plugin structures.

Capabilities

• **Context Analysis**: Deep analysis of token usage patterns
• **MECW Assessment**: Validates compliance with Maximum Effective Context Window principles
• **Optimization Execution**: Implements recommended optimizations
• **Growth Monitoring**: Tracks and predicts context growth

When To Use

Dispatch this agent for:

• Full context audits across large skill collections
• Automated optimization of skills exceeding token budgets
• Pre-release context compliance verification
• Periodic health checks of plugin context efficiency

When NOT To Use

• Single skill optimization
• use optimizing-large-skills skill
• Single skill optimization
• use optimizing-large-skills skill

Agent Workflow

Step 0: Complexity Check (MANDATORY)

Before any work, assess if this task justifies subagent overhead:

**Return early if**:

• Single skill token count → "SIMPLE: `wc -w skill.md` or parent estimates"
• Quick MECW check → "SIMPLE: Parent reads file and checks against threshold"
• One-off file size query → "SIMPLE: Parent uses Read tool"

**Continue if**:

• Full plugin audit (multiple skills)
• Growth trend analysis across time
• Optimization recommendations needed
• Pre-release compliance verification

Steps 1-5 (Only if Complexity Check passes)

1. **Discovery**: Find all SKILL.md files in target directory 2. **Analysis**: Calculate token usage and growth patterns for each 3. **Assessment**: Evaluate against MECW thresholds 4. **Recommendations**: Generate prioritized optimization suggestions 5. **Reporting**: Produce detailed context health report

Example Dispatch

Use the context-optimizer agent to analyze all skills in the conserve plugin
and generate a prioritized list of optimization opportunities.

Output Format

The agent produces a structured report including:

• Summary statistics (total files, total tokens, average per file)
• Skills exceeding thresholds with specific recommendations
• Growth trajectory predictions
• Suggested modularization opportunities

Integration

This agent uses tools from:

• `scripts/growth_analyzer.py` - Growth pattern analysis
• `scripts/growth_controller.py` - Optimization execution
• `abstract` plugin - Token estimation utilities
