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 | $0.00026 | $0.00767 |
| Opus 5 | $0.00013 | $0.00383 |
| Sonnet 5 | $0.00005 | $0.00153 |
| Haiku 4.5 | $0.00003 | $0.00077 |
Grade A, and why
f-implement 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 9d 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.

Implement — FreeCAD Edition
Implement FreeCAD geometry, assemblies, or FEM analysis based on a spec or ticket.
Context
- FreeCAD MCP server running on localhost
- MCP tools:
create_document,create_object,edit_object,delete_object,execute_code,get_view,run_fem_analysis - FreeCAD docs:
/home/praveen/Desktop/Freecadmcp/docs/freecad/ - Object reference:
/home/praveen/Desktop/Freecadmcp/.opencode/skills/freecad-objects/
Process
1. Read the ticket/spec
Extract the FreeCAD objects, dimensions, materials, and constraints to create.
2. Create the document
create_document(name="ProjectName")
3. Create objects in order
Follow the ticket's blocking edges. For each object:
create_object(
doc_name="ProjectName",
obj_name="ObjectName",
obj_type="Part::Box", # or Part::Cylinder, PartDesign::Pad, etc.
obj_properties={
"Length": 50,
"Width": 30,
"Height": 20,
"ViewObject": {"ShapeColor": [0.8, 0.2, 0.2, 1.0]},
"Placement": {"Base": {"x": 0, "y": 0, "z": 0}}
}
)
4. Verify with screenshots
After creating each major object:
get_view(view_name="Isometric", focus_object="ObjectName")
5. Run FEM analysis (if applicable)
run_fem_analysis(
doc_name="ProjectName",
analysis_name="FEMAnalysis",
timeout=600
)
6. Verify results
- Check max von Mises stress < material yield strength
- Check displacement within tolerance
- Get screenshot of stress visualization
7. Review the work
Use /f-code-review to verify:
- Standards: Objects use correct types and properties per FreeCAD docs
- Spec: All dimensions, features, and constraints match the ticket
8. Save the document
execute_code(code="FreeCAD.ActiveDocument.save('/path/to/file.FCStd')")
FreeCAD Object Quick Reference
| obj_type | Key Properties |
|---|---|
| Part::Box | Length, Width, Height |
| Part::Cylinder | Radius, Height |
| Part::Sphere | Radius |
| Part::Cone | Radius, Radius2, Height |
| Part::Torus | Radius, Radius2 |
| Draft::Circle | Radius |
| Draft::Rectangle | Length, Width |
| Draft::Polygon | Points, Radius |
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.

f-implement is a skill published in the GitHub repository GadatheGod/freecad-mcp-pro (1 stars, last pushed 1mo ago), licensed MIT. It adds 26 tokens to every session and 767 once invoked, about $0.0001 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 2026-08-31.
