Comparison Matrix
This page compresses the handbook into one comparison surface. Use it when you want to compare product shapes quickly before reading the detail pages.
Legend:
strongmeans the product shape usually owns that layer directlypartialmeans it often owns part of the layer or exposes it through another hostdelegatedmeans the layer usually exists outside the product
Product-shape matrix
| Product shape | 1-3 Model supply | 4-6 Agent system | 7-9 Operating boundary | 10-11 Surface |
|---|---|---|---|---|
| Bare model API | strong | delegated | delegated | partial |
| Model gateway | strong in 2-3 | delegated | delegated | partial |
| Agent framework library | delegated | strong | delegated | delegated |
| Coding agent CLI | delegated or partial | strong | strong or partial | strong |
| Hosted agent platform | partial | strong | strong or partial | strong |
| IDE extension over an agent | delegated | delegated or partial | partial | strong |
What the matrix is good for
- spotting over-claimed products quickly
- separating visible UI strength from deeper system ownership
- comparing two products that feel similar but own different parts of the stack
What the matrix is not for
- final classification of a specific product
- edge cases where one product bundles another
- situations where deployment mode changes the layer boundary
For those cases, continue with `03-placement-checklist.md` and `layers.md`.
