deploy

deploy is a skill for Claude Code, Codex from deeleeramone/PyWry. It costs 0 tokens per session (1,658 once invoked), scanned A, original, Apache-2.0.

A guide to running PyWry widgets on a production server that serves many users at once. It describes stateless widgets, externally stored state, persistent URLs, and scaling across multiple servers.

In plain words
What is it for?
Use it when deploying PyWry behind a load balancer, supporting concurrent users, keeping state outside the widget process, or scaling the service horizontally.
Why use it?
It explains how production deployments differ from a local or single-user widget. This helps avoid relying on in-memory widget state when requests may reach different servers.

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

deploy 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 1mo 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.

Production Deploy Mode

CRITICAL: This mode is for production servers serving multiple concurrent users. Widgets are stateless. State lives externally. Scale horizontally.

What Deploy Mode IS

You're creating widgets for a production SSE server with:

  • Multiple concurrent users/sessions
  • Stateless widget creation
  • Horizontal scaling support
  • Persistent widget URLs

Key Principles

Widgets Are Stateless

  • Widget instances don't persist server state
  • Store state externally (Redis, database, etc.)
  • Any server can handle any widget update

Session Management

  • Each user gets a unique widget_id
  • Map widget_id to user session externally
  • Implement timeouts and cleanup

Horizontal Scaling

  • Servers behind load balancer
  • SSE connections are per-server (sticky sessions may help)
  • Widget operations are idempotent

Best Practices

1. Widget IDs - Use Meaningful IDs

# Include user/session info in widget_id
widget_id = f"user_{user_id}_dashboard"

# Or use session-scoped IDs
widget_id = f"session_{session_id}_chart"

# This makes debugging and monitoring easier

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.

deploy is a skill published in the GitHub repository deeleeramone/PyWry (98 stars, last pushed 4d ago), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 1,658 tokens. 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.
