ros2-claude-code-template: Skill for Claude Code

.claude/skills/new-component/SKILL.md

new-component is a skill for Claude Code from harunkurtdev/ros2-claude-code-template. It costs 55 tokens per session (931 once invoked), scanned A, original, no licence file.

A guide for adding a new per-entity data field to gz-sim's Entity-Component-System, an architecture where entities hold reusable components and systems process them. It covers the component header, build listing, and optional serialization registration.

In plain words
What is it for?
Use it when creating a component under include/gz/sim/components/ or registering it with ComponentFactory for serialization.
Why use it?
It identifies the repository changes needed for a new simulation component. This helps avoid adding the header without also updating the build or serialization setup.

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

new-component 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.

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.
