What it does

Numerical Integration is an agent skill from FreedomIntelligence/OpenClaw-Medical-Skills. Select and configure time integration methods for ODE/PDE simulations. Use when choosing explicit/implicit schemes, setting error tolerances, adapting time steps, diagnosing integration accuracy, planning IMEX splitting, or handling stiff/non-stiff coupled systems.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 13 other files, including scripts and reference files (for example `references/error_control.md`, `references/imex_guidelines.md` and `references/method_catalog.md`).

The repository describes itself as: The largest open-source medical AI skills library for OpenClaw🦞.

When your agent uses it

  • Choosing explicit/implicit schemes
  • Setting error tolerances
  • Adapting time steps
  • Diagnosing integration accuracy

Example prompts

  • “/numerical-integration”

Requirements

  • Python 3
  • Pre-approved tools (allowed-tools): Read, Bash, Write, Grep, Glob

Workflow steps

7 steps, taken from the first numbered list in SKILL.md.

  1. Classify stiffness - Check eigenvalue spread or use stiffness_detector
  2. Choose tolerances - See references/tolerance_guidelines.md
  3. Select integrator - Run scripts/integrator_selector.py
  4. Compute error norms - Use scripts/error_norm.py for step acceptance
  5. Adapt step size - Use scripts/adaptive_step_controller.py
  6. Plan IMEX/splitting - If mixed stiff/nonstiff, use scripts/imex_split_planner.py
  7. Validate convergence - Repeat with tighter tolerances

What it can do on your machine

Read from SKILL.md and the folder at commit b1f9b6e. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves these tools, so the agent can use them without asking each time:

    • Read
    • Bash
    • Write
    • Grep
    • Glob

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 5 files in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • python3

    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

Numerical Integration loads about 1.5k tokens when it runs, and up to ~13k if it reads all its reference files. Until then it costs about 72 tokens; SKILL.md has 449 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~72
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~13k

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.

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NotePre-approves every shell command (allowed-tools: Bash)SKILL.md
    allowed-tools: Read, Bash, Write, Grep, Glob

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); the scripts in this folder are not scanned.

SKILL.md

Without a licence we can't republish the file, so here is its outline and opening line. It has 449 words (~1,547 tokens).

“Provide a reliable workflow to select integrators, set tolerances, and manage adaptive time stepping for time-dependent simulations.”

When should I use Numerical Integration?

Numerical Integration fits situations like: choosing explicit/implicit schemes; setting error tolerances; adapting time steps; diagnosing integration accuracy.

How do I install Numerical Integration in Claude Code?

Run `npx skills add FreedomIntelligence/OpenClaw-Medical-Skills --skill numerical-integration -a claude-code`. Or copy the skill folder (skills/numerical-integration in FreedomIntelligence/OpenClaw-Medical-Skills) into .claude/skills/numerical-integration in your project. Claude Code loads it when a task matches its description.

How do I install Numerical Integration in Codex?

Run `npx skills add FreedomIntelligence/OpenClaw-Medical-Skills --skill numerical-integration -a codex`. Or copy the skill folder (skills/numerical-integration in FreedomIntelligence/OpenClaw-Medical-Skills) into .agents/skills/numerical-integration in your project. Codex loads it when a task matches its description.

Can I use Numerical Integration 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 FreedomIntelligence/OpenClaw-Medical-Skills --skill numerical-integration -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/numerical-integration, .gemini/skills/numerical-integration, .github/skills/numerical-integration and .opencode/skills/numerical-integration in your project.

What does Numerical Integration need to run?

Going by SKILL.md and its folder, Numerical Integration needs Python for the scripts in its folder and the command-line tools its instructions call (python3). Our summary lists: Python 3. Its frontmatter pre-approves these tools: Read, Bash, Write, Grep, Glob.

Does Numerical Integration 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 Numerical Integration safe to install?

Our automated static check of SKILL.md found notes only (pre-approves every shell command (allowed-tools: bash)), nothing it rates as a warning. It is not a guarantee. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.

What licence does Numerical Integration use?

No licence was found for Numerical Integration or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.

How many tokens does Numerical Integration use?

About 1.5k tokens (SKILL.md is roughly 6.2k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 11k tokens, read only when the agent opens those files.

What are the alternatives to Numerical Integration?

Skills that share tags, products or a category with Numerical Integration: Finetuning Method Selection (wshobson/agents, 40k stars), Numerical Methods (brycewang-stanford/Auto-Empirical-Research-Skills, 4.5k stars), Select Name (thedaviddias/Front-End-Checklist, 74k stars) and Configuration (greenpau/caddy-security, 2.3k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
