Master skill for Abaqus FEA scripting. An agent skill from Cai-aa/CAE-Agent-Hub.

  • Works in 3 steps: Understand what the user wants → Route to the appropriate specialized skill → Ask clarifying questions if unclear
  • Any finite element analysis
  • SKILL.md covers When to Use This Skill, Routing Guide: User Intent to…, Decision Tables and What to Ask If Unclear, plus 5 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Abaqus is an agent skill from Cai-aa/CAE-Agent-Hub. Master skill for Abaqus FEA scripting. Use for any finite element analysis, topology optimization, or Abaqus Python scripting task. Routes to appropriate specialized skills.

Its SKILL.md is about 1.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files (for example `UPSTREAM.md` and `metadata.json`).

It sits in Research & Science, covering Physical and earth sciences. It works with Python. The licence is MIT.

When your agent uses it

  • Any finite element analysis
  • Topology optimization
  • Abaqus Python scripting task

Example prompts

  • “/abaqus”

Requirements

  • Python 3
  • Pre-approved tools (allowed-tools): Read, Write, Edit, Glob, Grep, Bash(abaqus:*), Bash(uv:*), Skill

Workflow steps

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

  1. Understand what the user wants
  2. Route to the appropriate specialized skill
  3. Ask clarifying questions if unclear

What it can do on your machine

Read from SKILL.md and the folder at commit 194ef49. 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
    • Write
    • Edit
    • Glob
    • Grep
    • Bash(abaqus:*)
    • Bash(uv:*)
    • Skill

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    No scripts in the folder and no shell commands in SKILL.md.

    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

Abaqus loads about 1.5k tokens when it runs. Until then it costs about 45 tokens; SKILL.md has 541 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~45
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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.
