litestar-granian

litestar-granian is a skill for Claude Code from litestar-org/litestar-skills. It costs 54 tokens per session (4,605 once invoked), scanned A, original, MIT.

A Litestar integration for running a Python web application with Granian, a web server. It covers server options such as worker threads, HTTP/2, TLS, access logs, metrics, and static files.

In plain words
What is it for?
Use it to register GranianPlugin, start a Litestar app, and configure supported runtime, logging, networking, and static-file settings.
Why use it?
It gives Litestar a Granian-backed run command and connects Granian’s logs with Litestar logging. This helps avoid using option names from incompatible server versions.

Token cost

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.

Security

Grade A, and why

litestar-granian 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 23d 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-granian

litestar-granian 0.16.0 replaces Litestar's run command with a supervised Granian command and bridges Litestar's active log formatter into Granian worker processes. It requires Granian 2.7.9 or later (the current lock uses 2.8.4).

Code Style Rules

  • Keep handlers async when they perform I/O.
  • Configure the server at the command line or programmatically via granian.Granian.
  • GranianPlugin takes only an optional static mode keyword argument ("off" or "auto").
  • Use the litestar run option names documented here. Do not substitute similarly named options from older Granian or Uvicorn releases.

Quick Reference

Register the plugin

from litestar import Litestar, get
from litestar_granian import GranianPlugin


@get("/health")
async def health() -> dict[str, str]:
    """Return health check response."""
    return {"status": "ok"}


app = Litestar(
    route_handlers=[health],
    plugins=[GranianPlugin()],
)
litestar --app app:app run

GranianPlugin registers the Granian-backed run command. When litestar run starts, litestar-granian inspects the active "litestar" standard-library logger (or app.logging_config, including standard_lib_logging_config wrapped by StructlogPlugin), serializes the active formatter into a temporary JSON dictConfig (--log-config), and reconstructs matching generic (_granian) and access (granian.access) formatters inside Granian worker processes.

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.
