About this Skill

Teachers and technical writers who explain machines on slides can hand their agent a checked description of one mechanism and get back three 16:9 diagrams at 1536×864. It looks like drawing paper with a faint grain: see-through housings in fine graphite, cool and warm washes showing what is cold, what is hot and what moves, and empty boxes tied to parts by thin leader lines. Before paying, the agent tables the parts and connections; afterwards it sets your labels and checks each link against that table.
How it works
- Write out the parts and how each one connects, and get that table approved before any drawing starts.
- Choose a single viewpoint and leave clear lanes around the subject for the callouts.
- Brief the model on pale see-through washes, thin graphite construction lines and a quiet paper texture.
- Generate the three variants in one paid call, asking the model for no small lettering.
- Set the approved labels afterwards and compare every visible link with the parts table.
Checked before delivery
- The three images differ from one another, are sharp and are exactly 16:9
- Every visible fact and relationship matches the approved inputs
- Exact labels and citations are set after generation, never drawn by the image model
- No logos, watermarks, borrowed identities, wrong anatomy, duplicated panels or unreadable hierarchy

FAQ
Does the image model write the labels?
No. It is asked for no small lettering; your approved terms go into the empty boxes once the picture exists.
Is 16:9 the only shape?
The generator renders 1536×864. If you need another final ratio, name it before the composition is planned.
Will it calculate flows or loads?
No. It pictures the facts you hand it and runs no simulation or engineering math.
