From the source SKILL.md

立花 venue 統合は Python 側 python/engine/exchanges/tachibana*.py にロジックを集約する。Rust 側はチャート描画と IPC ライフサイクルイベントに責務を絞り、立花プロトコル固有のヘルパー(URL ビルド・Shift-JIS デコード・p_no 採番・WS 接続)は Rust に書かない([architecture.md §1](../../../docs/✅tachibana/architecture.md))。本スキルは Claude が API 仕様に正しく沿って Python / IPC コードを書くためのルール集である。

What this skill does

Tachibana is a community-contributed Claude Code skill in the backend sub-category. It ships as a SKILL.md file that Claude Code auto-discovers under ~/.claude/skills/tachibana/ and loads when your prompt matches the skill's trigger.

Who uses this skill

The Tachibana Claude Code skill is built for software engineers, backend developers, full-stack teams, and technical leads building and maintaining production systems. It's part of ClaudSkills (also referred to as Claude Skills or Claude Code Skills) — the open community-curated registry of 116,000+ SKILL.md files for Anthropic's Claude Code agent and the wider Claude ecosystem (Claude API, Claude Agent SDK).

Is this skill free to install?
Yes. ClaudSkills is an open registry — every skill keeps its source repository's license, and manual install via copy is free. ClaudSkills Pro ($9/mo, $79/yr, or $149 one-time) adds one-click install via the desktop app and a multi-signal Quality Score.
When should I use the Tachibana skill?
Use Tachibana when your Claude Code task falls under the Engineering category — specifically in the backend area. Claude Code auto-discovers installed skills and invokes the right one based on the task description, so you can also ask Claude directly (e.g. "use Tachibana" or describe the task and let Claude pick). Browse related skills at /category/engineering/.
What is a Claude Code skill and how does the Tachibana skill fit in?
A Claude Code skill is a SKILL.md file that lives under ~/.claude/skills/<name>/ and tells the Claude Code CLI agent how to perform a specific task (instructions, prompts, allowed tools). Skills are auto-discovered at session start. Tachibana is one of 67,000+ skills indexed in the open ClaudSkills catalog, classified under the Engineering category.
