Plan and control time-step policies for simulations. An agent skill from FreedomIntelligence/OpenClaw-Medical-Skills.

  • Works in 5 steps: Get stability limits - Use… → Plan time stepping - Run… → Schedule outputs - Run… → …
  • Coupling CFL/physics limits with adaptive stepping
  • SKILL.md covers Goal, Requirements, Inputs to Gather and Decision Guidance, plus 10 more sections
  • Runs Python scripts from its folder; calls python3

What it does

Time Stepping is an agent skill from FreedomIntelligence/OpenClaw-Medical-Skills. Plan and control time-step policies for simulations. Use when coupling CFL/physics limits with adaptive stepping, ramping initial transients, scheduling outputs/checkpoints, or planning restart strategies for long runs.

Its SKILL.md is about 1.1k tokens, which your agent loads only when the skill is triggered. The skill folder holds 8 other files, including scripts and reference files (for example `references/cfl_coupling.md`, `references/output_checkpoint_guidelines.md` and `references/ramping_strategies.md`).

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

When your agent uses it

  • Coupling CFL/physics limits with adaptive stepping
  • Ramping initial transients
  • Scheduling outputs/checkpoints
  • Planning restart strategies for long runs

Example prompts

  • “/time-stepping”

Requirements

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

Workflow steps

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

  1. Get stability limits - Use numerical-stability skill
  2. Plan time stepping - Run scripts/timestep_planner.py
  3. Schedule outputs - Run scripts/output_schedule.py
  4. Plan checkpoints - Run scripts/checkpoint_planner.py
  5. Monitor during run - Adjust dt if limits change

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 3 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

Time Stepping loads about 1.1k tokens when it runs, and up to ~7.3k if it reads all its reference files. Until then it costs about 58 tokens; SKILL.md has 349 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~58
When it runs · the whole SKILL.md, loaded when a task matches
~1.1k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~7.3k

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 349 words (~1,121 tokens).

“Provide a reliable workflow for choosing, ramping, and monitoring time steps plus output/checkpoint cadence.”

Can I use Time Stepping 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 time-stepping -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/time-stepping, .gemini/skills/time-stepping, .github/skills/time-stepping and .opencode/skills/time-stepping in your project.

What does Time Stepping need to run?

Going by SKILL.md and its folder, Time Stepping 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 Time Stepping 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 Time Stepping 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 Time Stepping use?

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

How many tokens does Time Stepping use?

About 1.1k tokens (SKILL.md is roughly 4.5k 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 6.1k tokens, read only when the agent opens those files.
