A skill your agent uses when running the simulator-with-failure test variant and the pre-race phase begins.
- Running the simulator-with-failure test variant and the pre-race phase begins
- Runs Python scripts from its folder
What it does
Simulating Pre Race Failure is an agent skill from GoogleCloudPlatform/race-condition. Use when running the simulator-with-failure test variant and the pre-race phase begins. The preparesimulation tool intentionally raises RuntimeError to exercise the ADK and SimulationCommunicationPlugin toolerror callback path. Not intended for production simulations.
Its SKILL.md is about 200 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `tools.py`).
The repository describes itself as: The open source multi-agent simulation from the Developer Keynote at Google Cloud Next '26. A deployable reference architecture for autonomous AI agents using Gemini and ADK. The licence is Apache-2.0.
When your agent uses it
- Running the simulator-with-failure test variant and the pre-race phase begins
Example prompts
- “/simulating-pre-race-failure”
Requirements
- Python 3
What it can do on your machine
Read from SKILL.md and the folder at commit 26efc1b. 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
Ships script files (Python), which the agent can run.
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
Simulating Pre Race Failure loads about 204 tokens when it runs. Until then it costs about 75 tokens; SKILL.md has 55 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.

Simulating Pre-Race Failure
This skill replaces the base simulator's pre-race setup with a version that
intentionally fails during prepare_simulation. It tests how the ADK and
SimulationCommunicationPlugin handle tool_error callbacks when the simulation
engine encounters failures.
Tools
prepare_simulation: Accepts a plan JSON string but raisesRuntimeErrorafter a brief processing delay, simulating an unhandled internal exception.
