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 | $0.00110 | $0.01686 |
| Opus 5.5 | $0.00044 | $0.00674 |
| Sonnet 5.5 | $0.00022 | $0.00337 |
| Haiku 4.5 | $0.00011 | $0.00169 |
Grade A, and why
techdrawai-cad 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.
How it starts
The opening of the file, as written. The whole thing — 86 lines — stays where its author put it; the contents beside it link to each section on GitHub.
TechDraw AI: CAD files, 3D models and renders
Everything downstream of a drawing. If the user needs the drawing itself first, use the techdrawai-drafting skill and come back here with what it wrote.
Setup (once)
npx -y techdrawai-mcp auth login # browser sign-in, no key to copy
Requires an active Studio plan. If a tool reports a plan error, say so plainly and point at https://techdrawai.com/app?view=subscription rather than retrying. Keys can also be created in Settings and passed as TECHDRAWAI_API_KEY.
Tools
image_to_dxf
Any raster image becomes real CAD vector contours in a DXF file. Free.
image(required): a generated drawing, a scan, a sketch, a logo, a photo of a flat part.width_mm: pass this whenever the real size is known. Without it the geometry arrives at one DXF unit per pixel and the user has to rescale by hand in CAD, which is exactly the annoying step they came here to avoid.threshold:"auto"(default) or a number 0 to 255 to force the ink and paper cut-off.invert: for light lines on a dark background.smoothing: 1 keeps detail, higher smooths the contours.dwg: also write AutoCAD's native.dwgbeside the.dxf.output_path: defaults to./techdrawai-output/.
The DXF is ASCII R2000 and opens in AutoCAD, Fusion 360, SolidWorks, Onshape, FreeCAD, LibreCAD, Rhino, Inkscape and the common laser and CNC tools such as LightBurn.
photo_to_3d
A photo of one object becomes a textured 3D mesh. 80 credits, Studio plan: a reconstruction runs for minutes on a GPU, so it is not priced like a drawing. Takes one to three minutes and the call blocks until the mesh is ready, so tell the user it is running rather than leaving them watching a stalled prompt.
image(required): a clear JPG or PNG of a single object.detail:draft(12k triangles),standard(40k, default),high(80k).textured: defaults to true. Turn it off when the user only wants geometry.output_path: the GLB lands here; FBX, OBJ, USDZ and STL links are reported too.
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.

techdrawai-cad is a skill published in the GitHub repository MeltFlexDevs/techdrawai-skills (3 stars, last pushed 10d ago), licensed MIT. It adds 110 tokens to every session and 1,686 once invoked, about $0.0004 per session on Opus 5.5. 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.
