orkid: Skill for Claude Code

.claude/skills/orklev2-particles/SKILL.md

orklev2-particles is a skill for Claude Code from tweakoz/orkid. It costs 83 tokens per session (2,692 once invoked), scanned A, original, MIT.

A reference guide to Orkid’s particle system, which creates and displays many small moving objects such as sparks, smoke, or rain.

In plain words
What is it for?
Use it to work with particle emitters, movement forces, visual renderers, materials, object pools, and Python bindings in Orkid.
Why use it?
It gives an agent the locations and concepts needed to answer particle-system questions without searching the whole codebase.

Skill for Claude Code

Written for Claude Code: user-invocable in frontmatter.

This is tweakoz/orkid's own configuration. It tells Claude Code how to work on orkid itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything orkid configures →

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

orklev2-particles 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 2mo 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.

Architecture Overview

The particle system is dataflow-graph-based — particles are processed by composable modules connected via typed plugs in a topologically-sorted computation graph.

Signal Flow

GlobalModule (time) ──→ Pool (allocate/age) ──→ Emitter (spawn)
                                                    │
                                              ──→ Forces (modify velocity)
                                                    │
                                              ──→ Renderer (draw)

Module Lifecycle

  1. Data Phase (ModuleData): created with createShared(), plugs defined in _reshapeIOs()
  2. Instance Phase (ModuleInst): createInstance(GraphInst*) → onLink() → per-frame compute()
  3. Execution: topological sort ensures dependencies resolve before dependents

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.

orklev2-particles is a skill published in the GitHub repository tweakoz/orkid (35 stars, last pushed 2mo ago), licensed MIT. It adds 83 tokens to every session and 2,692 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-01.
