What it does
Gz Ecs Overview is an agent skill from harunkurtdev/ros2-claude-code-template. Concise reference for the gz-sim Entity-Component-System architecture — how Entities, Components, Systems, the ECM, the Server, and SimulationRunner fit together. Trigger when the user asks how gz-sim is organized, where to add code, or how the simulation loop runs.
Its SKILL.md is about 1.2k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
When your agent uses it
- The user asks how gz-sim is organized
- Where to add code
- How the simulation loop runs
Example prompts
- “/gz-ecs-overview”
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- include/gz/sim/EntityComponentManager.hh — every comment matters.
- include/gz/sim/System.hh — the interfaces are tiny and tell you
What it can do on your machine
Read from SKILL.md and the folder at commit 5b3a43d. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are cpp).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Gz Ecs Overview loads about 1.2k tokens when it runs. Until then it costs about 71 tokens; SKILL.md has 382 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 382 words (~1,230 tokens).
“topics. Do not mutate the world here unless you're spawning fixtures.”
