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.

What 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 5.1 | $0.00054 | $0.00560 |
| Opus 5 | $0.00027 | $0.00280 |
| Sonnet 5 | $0.00011 | $0.00112 |
| Haiku 4.5 | $0.00005 | $0.00056 |
Grade A, and why
litestar-realtime 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 12d 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.

Litestar Realtime
Use this skill for WebSockets, SSE, ChannelsPlugin backends, realtime event contracts, and fan-out from workers or services.
Code Style Rules
- Use plain WebSocket handlers for one-off streams.
- Use ChannelsPlugin when dynamic topics, history, or cross-process fan-out matter.
- Choose the backend that matches the existing stack.
- Treat WebSocket auth separately from HTTP header auth constraints.
Quick Reference
- WebSocket and Channels patterns: websockets.md
- Event contract patterns: realtime-events.md
- Pair with litestar-auth-guards for socket auth.
Workflow
- Choose WebSocket, SSE, or Channels based on delivery needs.
- Define event contracts before wiring transport.
- Select a backend that fits the project stack.
- Test connection, auth, fan-out, disconnect, and error paths.
Guardrails
- Do not force Redis into a PostgreSQL-only stack just for Channels.
- Do not assume browsers can set arbitrary WebSocket headers.
- Do not publish untyped event dicts across service boundaries.
- Do not use request-scoped resources after the socket lifecycle ends.
Validation Checkpoint
- Transport choice matches the user experience.
- Event payloads are typed.
- Backend choice matches the stack.
- Auth and disconnect behavior are tested.
Example
from litestar import websocket
@websocket("/ws")
async def stream(socket: WebSocket) -> None:
await socket.accept()
await socket.send_json({"type": "ready"})

What ships with it
2 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

litestar-realtime is a skill published in the GitHub repository litestar-org/litestar-skills (14 stars, last pushed 22d ago), licensed MIT. It adds 54 tokens to every session and 560 once invoked, about $0.0003 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 2026-08-30.
