What it does

Nonlinear Solvers is an agent skill from FreedomIntelligence/OpenClaw-Medical-Skills. Select and configure nonlinear solvers for f(x)=0 or min F(x). Use for Newton methods, quasi-Newton (BFGS, L-BFGS), Broyden, Anderson acceleration, diagnosing convergence issues, choosing line search vs trust region, and analyzing Jacobian quality.

Its SKILL.md is about 1.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 12 other files, including scripts and reference files (for example `references/convergence_diagnostics.md`, `references/globalization_strategies.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

  • Quasi-Newton (BFGS
  • Anderson acceleration
  • Diagnosing convergence issues
  • Choosing line search vs trust region

Example prompts

  • “/nonlinear-solvers”

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. Characterize problem - Identify type, size, Jacobian availability
  2. Select solver - Run scripts/solver_selector.py
  3. Choose globalization - Run scripts/globalization_advisor.py
  4. Analyze Jacobian - If available, run scripts/jacobian_diagnostics.py
  5. Monitor residuals - During solve, use scripts/residual_monitor.py
  6. Analyze convergence - Run scripts/convergence_analyzer.py
  7. Evaluate steps - For trust region, use scripts/step_quality.py

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 6 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

Nonlinear Solvers loads about 1.8k tokens when it runs, and up to ~11k if it reads all its reference files. Until then it costs about 67 tokens; SKILL.md has 504 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~67
When it runs · the whole SKILL.md, loaded when a task matches
~1.8k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~11k

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 504 words (~1,796 tokens).

“Provide a universal workflow to select a nonlinear solver, configure globalization strategies, and diagnose convergence for root-finding, optimization, and least-squares problems.”

What does Nonlinear Solvers need to run?

Going by SKILL.md and its folder, Nonlinear Solvers 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 Nonlinear Solvers 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 Nonlinear Solvers 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.
