What it does
Simskill is an agent skill from autonomous-ai/openharness. Create and inspect simulation projects in the SimSkill Harness workspace, including its local starter and optional upstream integration.
Its SKILL.md is about 510 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: The ultimate harness for coding agents and beyond. All your agents. All your machines. One command center. Start with code, then follow your curiosity and build across… The licence is MIT.
Example prompts
- “/simskill”
What it can do on your machine
Read from SKILL.md and the folder at commit 50da5db. 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.
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
Simskill loads about 512 tokens when it runs. Until then it costs about 36 tokens; SKILL.md has 240 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.

City lab
Read studio.json to understand the current controls; "$STUDIO_TOOLCHAIN/../studio.config.json"
describes their ranges. Run "$STUDIO_TOOLCHAIN/run.sh" simulate to make a new result.
Successful artifacts and their measurements are in out/runs/<id>/; out/latest.json names the
current result. A failed run preserves the last success and records the error in the verdict.
The local workflow generates an original four-way intersection with SUMO netconvert and simulates actual traffic with SUMO. Playback uses its floating-car output. A comparison is a simulation experiment, not a calibrated forecast for a real city. Intel Macs build pinned SUMO 1.27.1 headlessly with package-local Xerces.
Use "$STUDIO_TOOLCHAIN/../README.md" for the integration contract and commands. Read the relevant
files under $STUDIO_UPSTREAM before using an upstream API. Keep controls within their documented
ranges, preserve the data needed to reproduce a comparison, and distinguish preview results from
native service or hardware output. The viewer supports history and artifact downloads; tell the
user which run contains the result, and what was actually measured.
Compare a signal plan
Record the baseline, then change east–west green time while holding demand, duration, and
seed fixed. Inspect trips.csv, the generated network, and raw traffic.xml. Compare mean
delay for completed trips together with the unfinished count and largest stopped queue.
Do not drop unfinished vehicles when describing congestion.
For custom networks, read $STUDIO_UPSTREAM/.claude/skills/procedural-memory/ in this order:
create-single-intersection/SKILL.md, run-simulation/SKILL.md, and
analyze-simulation-outputs/SKILL.md. Those pinned procedures explain the native SUMO
commands and raw outputs. The starter is an original intersection, not a calibrated city.

Create and inspect simulation projects in the SimSkill Harness workspace, including its local starter and optional upstream integration.
How do I install Simskill in Claude Code?
Run `npx skills add autonomous-ai/openharness --skill simskill -a claude-code`. Or copy the skill folder (store/agents/simskill/skills/simskill in autonomous-ai/openharness) into .claude/skills/simskill in your project. Claude Code loads it when a task matches its description.
How do I install Simskill in Codex?
Run `npx skills add autonomous-ai/openharness --skill simskill -a codex`. Or copy the skill folder (store/agents/simskill/skills/simskill in autonomous-ai/openharness) into .agents/skills/simskill in your project. Codex loads it when a task matches its description.
Can I use Simskill in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add autonomous-ai/openharness --skill simskill -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/simskill, .gemini/skills/simskill, .github/skills/simskill and .opencode/skills/simskill in your project.
What does Simskill need to run?
SKILL.md names no scripts, command-line tools or credentials: Simskill is instructions for the agent only.
Does Simskill access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Simskill safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Simskill use?
Simskill is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Simskill use?
About 512 tokens (SKILL.md is roughly 2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
What are the alternatives to Simskill?
Skills that share tags, products or a category with Simskill: Node Inspect Debugger (openclaw/openclaw, 392k stars), Eas Simulator (sickn33/agentic-awesome-skills, 47k stars), Blender Motion State Inspection (affaan-m/ECC, 275k stars) and Inspect Disk (felixrieseberg/windows95, 24k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Simskill?
autonomous-ai (a GitHub organization) maintains it in autonomous-ai/openharness, which has 1,149 GitHub stars. The repository holds 100 skills in this directory. The repository was last updated on October 8, 2026.
