orkid: Skill for Claude Code

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

orklev2-fbi is a skill for Claude Code from tweakoz/orkid. It costs 73 tokens per session (1,690 once invoked), scanned A, original, MIT.

A reference guide to Orkid’s FrameBufferInterface, the part of its graphics system that controls render targets, viewports, screen clearing, and captured pixels.

In plain words
What is it for?
Use it for render-target management, viewport and scissor settings, framebuffer clearing, multisample resolving, pixel capture, and picking.
Why use it?
It helps developers locate the right APIs and source files for directing where graphics are drawn and reading back rendered results.

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-fbi scanned grade A with 1 finding 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 8d 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.

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-fbi is a skill published in the GitHub repository tweakoz/orkid (35 stars, last pushed 28d ago), licensed MIT. It adds 73 tokens to every session and 1,690 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-01.
