Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00038 | $0.01079 |
| Opus 5 | $0.00019 | $0.00540 |
| Sonnet 5 | $0.00008 | $0.00216 |
| Haiku 4.5 | $0.00004 | $0.00108 |
Grade A, and why
abaqus-shape-optimization 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.
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 Shape Optimization Skill
Optimize surface geometry to reduce stress concentrations. Shape optimization moves existing surfaces without adding or removing material.
When to Use This Skill
Route here when user mentions:
- "stress concentration", "reduce peak stress"
- "fillet optimization", "optimize fillet radius"
- "reshape surface", "smooth geometry"
- "improve fatigue life", "notch optimization"
Route elsewhere:
- Adding/removing material (holes, organic forms) →
/abaqus-topology-optimization - Low-level optimization setup →
/abaqus-optimization - Running the optimization job →
/abaqus-job
Shape vs Topology Optimization
| Aspect | Shape Optimization | Topology Optimization |
|---|---|---|
| What changes | Surface positions | Material presence |
| Result | Smooth surfaces | Holes, organic forms |
| Manufacturing | Traditional machining | Often needs AM/casting |
| Design freedom | Limited | High |
| Best for | Refine existing design | Conceptual design |
Rule of thumb: Use shape optimization when you have a good design with local stress issues. Use topology when starting fresh or need major redesign.
Prerequisites
Before shape optimization:
- ✅ Working static analysis that converges
- ✅ Identified high-stress surface region
- ✅ Full Abaqus license with Tosca (not Learning Edition)
Workflow: Shape Optimization
Step 1: Run Baseline Analysis
Run static analysis to identify stress concentrations. Note peak stress location and magnitude for comparison baseline.
Step 2: Identify Design Surfaces
Ask user if unclear: Which surfaces can be modified? Which must remain fixed?
Only select surfaces that can be modified in manufacturing, are not functional interfaces, and don't have attached features.
Step 3: Define Movement Limits
Get maximum growth/shrink (mm). Typical values: 3-10mm depending on part size.
Step 4: Choose Objective
| User Goal | Objective | Design Response |
|---|---|---|
| Reduce stress concentration | MINIMIZE_MAXIMUM | STRESS (MISES) |
| Uniform stress distribution | MINIMIZE_MAXIMUM | MAX_PRINCIPAL_STRESS |
| Maximize stiffness | MINIMIZE_MAXIMUM | STRAIN_ENERGY |
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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-shape-optimization is a skill published in the GitHub repository Cai-aa/CAE-Agent-Hub (839 stars, last pushed 3d ago), licensed MIT. It adds 38 tokens to every session and 1,079 once invoked, about $0.0002 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.
