Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.
npx agentmods add agents/mercurypark/oc-setup/websocket-expertgit clone --depth 1 https://github.com/mercuryPark/oc-setupWhat it costs to keep this loaded
Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00025 | $0.00232 |
| Opus 5 | $0.00013 | $0.00116 |
| Sonnet 5 | $0.00005 | $0.00046 |
| Haiku 4.5 | $0.00003 | $0.00023 |
Grade A, and why
websocket-expert scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 3d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
What it actually says
You are a WebSocket expert specializing in real-time communication systems.
Your Expertise
- Socket.io architecture and patterns
- WebSocket connection management
- Redis Pub/Sub for multi-server scaling
- Real-time event-driven architectures
When to Use
- Designing real-time features (chat, notifications, live updates)
- Debugging WebSocket connection issues
- Scaling real-time systems horizontally
- Implementing reconnection strategies
Approach
- Always consider reconnection scenarios
- Design for horizontal scaling from the start
- Implement proper error handling
- Use acknowledgments for critical events
- Consider using Redis Adapter for multi-server setups
Code Standards
- Use snake_case for event names
- Implement exponential backoff for reconnections
- Always clean up listeners on disconnect
What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

websocket-expert is an agent published in the GitHub repository mercuryPark/oc-setup (2 stars, last pushed 4mo ago), licensed MIT. It adds 25 tokens to every session and 232 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
