Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

abaqus-sim scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (base/workflows/cantilever/evidence/run/view_results.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

abaqus-sim

This file is the Abaqus index. Use sim-cli for solver execution and live CAE authoring; use portable Python text parsing for completed text artifacts when the job files are already on disk.

Abaqus is a commercial finite element analysis (FEA) solver by Dassault Systemes SIMULIA. The sim plugin supports two execution styles:

  1. Batch execution for complete .inp decks or Abaqus/CAE Python files.
  2. CAE authoring sessions for iterative model creation, inspection, debugging, job submission, and report preparation. The default backend is file-backed; the optional bridge backend keeps one noGUI CAE process alive for faster agent loops.

It supports two script formats:

  • Input decks (.inp) — keyword-driven text files defining geometry, materials, loads, BCs, and analysis steps
  • Abaqus/CAE Python scripts (.py) — Python scripts using the abaqus and abaqusConstants modules for parametric model building

The driver runs these via subprocess (abaqus job=X input=file.inp interactive or abaqus cae noGUI=script.py). In CAE authoring sessions, each uv run sim exec snippet runs inside Abaqus/CAE against a saved session .cae database, then saves the database back for the next step. With --backend bridge, snippets are sent to one long-lived noGUI CAE process over a localhost command channel protected by a per-session token. Use bridge mode only in trusted workspaces owned by the session user. No Abaqus Python module is imported into the sim process.

This is not the Ansys Mechanical plugin. Do not route Abaqus .inp decks or Abaqus/CAE Python scripts through solver=mechanical; use solver=abaqus for Abaqus execution/authoring and solver=mechanical only for PyMechanical / Ansys Mechanical sessions.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

abaqus-sim is a skill published in the GitHub repository svd-ai-lab/sim-plugin-abaqus (13 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 77 tokens to every session and 2,155 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
