Metadata-only prompts are built but NOT YET ENABLED by default.
The infrastructure exists:
- ✅ core/agent_loader.py - Supports both formats
- ✅ core/generate_agent_metadata.py - Generates metadata listings
- ✅ scripts/enable_metadata_prompts.sh - One-command enablement
- ✅ Full documentation in METADATA_ONLY_PROMPTS.md
But CLAUDE.md still uses full agent definitions for 100% backward compatibility.
- Conservative Approach: Existing users have working systems
- Testing Period: New architecture needs real-world validation
- User Choice: Some may prefer full definitions for transparency
- Gradual Migration: Allows opt-in adoption
- You have 20+ agents - Significant benefits at this scale
- Planning to scale to 50+ - Essential for growth
- Token costs matter - 93% reduction in prompt tokens
- Classification is slow - Faster with less context
- Using multi-file agents - Designed for this architecture
- You have <10 agents - Benefits are minimal
- Single-file agents only - Full definitions already small
- System is working perfectly - "If it ain't broke..."
- Risk-averse - Wait for more community validation
cd ~/Projects/claude-oak-agents
./scripts/enable_metadata_prompts.shWhat it does:
- Backs up current CLAUDE.md
- Generates metadata-only agent listing
- Replaces agent matrix with metadata
- Shows before/after size comparison
Expected output:

If you prefer manual control:
-
Generate metadata listing:
python3 core/generate_agent_metadata.py \ --agents-dir=agents \ --format=compact \ --output=/tmp/agent_metadata.txt
-
Edit CLAUDE.md:
- Find the
<Rule id="agent-responsibility-matrix">section - Replace the detailed agent matrix with:

[Repeat for 29 agents = 87KB]## Agent Responsibility Matrix (Metadata-Only Discovery)
**NOTE**: Full agent definitions are loaded on-demand when invoked.
This achieves 93% size reduction while maintaining discovery capabilities.
# Available Agents (Ultra-Compact)
**Total**: 29 agents | Full definitions loaded on-demand
- **frontend-developer** [medium]: react, vue, ui, frontend, component
- **backend-architect** [medium]: api, database, backend, server, microservices
- **security-auditor** [high]: security, vulnerability, audit, compliance | Scripts: 3 | BLOCKING
...
[29 agents = 6KB]
### Agent Selection Process
1. Keyword matching against triggers
2. File pattern matching
3. Domain matching
4. Load full definition on-demand when invoked| Measure | Before | After | Improvement |
|---|---|---|---|
| CLAUDE.md size | 89KB | 9KB | 90% smaller |
| Agent matrix | 87KB | 6KB | 93% smaller |
| Load time | ~2s | ~0.5s | 4x faster |
| Agents supported | ~30 | 100+ | 3x+ scalability |
Per conversation:
- Before: 89K tokens (system prompt) + task tokens
- After: 9K tokens (metadata prompt) + task tokens
- Savings: 80K tokens
Monthly (1000 conversations):
- Before: 89M tokens
- After: 9M tokens
- Savings: 80M tokens ≈ $160/month (GPT-4 pricing)
Request: "Fix security vulnerability in authentication"
Before (Full Definitions):
1. Load 87KB agent matrix into context
2. Search through 29 detailed definitions
3. Match keywords and patterns
Time: ~2 seconds
After (Metadata-Only):
1. Load 6KB metadata
2. Quick keyword match: "security", "vulnerability", "authentication"
3. Match to security-auditor
4. Load full definition on-demand
Time: ~0.5 seconds
The script creates timestamped backups:
# List backups
ls -lh CLAUDE.md.backup.*
# Restore from backup
cp CLAUDE.md.backup.20251016_103000 CLAUDE.mdIf you need to revert manually:
git checkout CLAUDE.md(Assuming CLAUDE.md is in git)
# Test metadata loading
python3 core/agent_loader.py --command=metadata
# Should show all 29 agentsCreate a test request in Claude Code:
User: "Review this code for security vulnerabilities"
Expected behavior:
- Main LLM matches keywords: "security", "vulnerabilities"
- Selects: security-auditor
- Loads full definition on-demand
- Executes agent normally
# Test bundled script
python3 agents/security-auditor-multifile/scripts/dependency_scan.py \
--directory=. \
--output-format=markdownShould work identically to before.
After enablement, monitor:
- Classification Accuracy: Are agents selected correctly?
- Loading Errors: Any "agent not found" errors?
- Performance: Is classification faster?
- Token Usage: Check token costs in Claude usage dashboard
A: No. The agent loader supports both single-file and multi-file formats. Existing agents work unchanged.
A: No. Metadata-only works with single-file agents too. The loader extracts metadata from frontmatter.
A: The system falls back to general-purpose agent and logs a routing failure. You can restore the full definitions anytime.
A: Yes. Edit core/generate_agent_metadata.py to change the output format.
A: No, as long as they have proper YAML frontmatter with name and description fields.
- Infrastructure built but not enabled
- Users can opt-in via script
- Gather feedback and validation
- Enable by default for new installations
- Existing users see notification about benefits
- Provide easy opt-in path
- Metadata-only becomes default
- Full definitions available as "legacy mode"
- Documentation assumes metadata-only
We're gathering feedback on metadata-only prompts:
