simulation-validator
Validate simulations before, during, and after execution. Use for pre-flight checks, runtime monitoring, post-run validation, diagnosing failed simulations, checking convergence, detecting NaN/Inf, or verifying mass/energy conservation.
npx skills add FreedomIntelligence/OpenClaw-Medical-Skills --skill simulation-validator --agent claude-code
Same command for any agent — swap --agent for codex, cursor, copilot.
Weekly change comes from our own snapshots, not the repository page — it measures attention, not adoption.
# Simulation Validator ## Goal Provide a three-stage validation protocol: pre-flight checks, runtime monitoring, and post-flight validation for materials simulations. ## Requirements - Python 3.8+ - No external dependencies (uses Python standard library only) - Works on Linux, macOS, and Windows ## Inputs to Gather Before running validation scripts, collect from the user: | Input | Description | Example | |-------|-------------|---------| | Config file | Simulation configuration (JSON/YAML) | `simulation.json` | | Log file | Runtime output log | `simulation.log` | | Metrics file | Post-run metrics (JSON) | `results.json` | | Required params | Parameters that must exist | `dt,dx,kappa` | | Valid ranges | Parameter bounds | `dt:1e-6:1e-2` | ## Decision Guidance ### When to Run Each Stage ``` Is simulation about to start? ├── YES → Run Stage 1: preflight_checker.py │ └── BLOCK status? → Fix issues, do NOT run simulation │ └── WARN status? → Review warnings, document if accepted │ └── PASS status? → Proceed to run simulation │ Is simulation running? ├── YES → Run Stage 2: runtime_monitor.py (periodically) │ └── Alerts? → Consider stopping, check parameters │ Has simulation finished? ├─

What does the simulation-validator skill do?
Validate simulations before, during, and after execution. Use for pre-flight checks, runtime monitoring, post-run validation, diagnosing failed simulations, checking convergence, detecting NaN/Inf, or verifying mass/energy conservation.
How do I install it?
Run `npx skills add FreedomIntelligence/OpenClaw-Medical-Skills --skill simulation-validator --agent claude-code` — it drops the skill into your project so the agent can pick it up. Swap the --agent value for codex, cursor or copilot if you use one of those.
Where does this skill come from?
From FreedomIntelligence/OpenClaw-Medical-Skills, a repository with 2,909 stars. We read it straight from the repository tree rather than a submitted listing, so what you see here is what is actually published.
Is a popular skill a good skill?
Not necessarily. Stars measure attention, not adoption — a repository can trend for a week and be abandoned. That is why we show the weekly change from our own snapshots next to the total, instead of a single flattering number.
