## Tools (as reported by the server, not verified)

- `structure`: What is this system? Returns shape \(Pipeline, Fork-Join, DAG, Star, Cycle, Tree, Complete, etc.\), stages with roles, bridge nodes, cycles, parallelism, critical path, dominator tree, min-cuts, subsystems, interface nodes, actors \(who does what, workload entropy\), locations \(where work happens, bound
- `invariant`: What's always true — automatic findings and on-demand checks. Automatic outputs: conservationLaws \(weighted entity sums constant across executions\), sustainableCycles \(T-invariants — action sequences returning to start state\), depletableSets \(entity groups whose simultaneous depletion is irreversibl
- `live`: Can it deadlock? Can entities overflow? isStructurallyLive means every siphon contains a trap — no structural deadlock possible. uncoveredSiphons are entity groups that can drain permanently, with the actors and locations affected. isStructurallyBounded means no entity can accumulate without limit.
- `reachable`: Can X reach Y? Follows directed data flow first; falls back to undirected. \`from\` and \`to\` accept entity names or action names \(resolved against the program\). Path shows each step with actor and location. locationCrossings counts boundary transitions. defense\_nodes checks if guards cover all paths;
- `equivalent`: Are two systems the same, or what changes if I change this one? Compare mode \(source\_a + source\_b\): structural differences, edit distance, spectral equivalence. isCospectral=true means identical graph structure up to relabeling — topologically the same despite different names, actors, or locations.
- `compose`: How do parts combine, or how does a part stand alone? Merge mode \(source\_a + source\_b + links\): declare which entities in A are the same as entities in B; the combined graph is wired via string-equality of shared names. Extract mode \(source + subsystem\): pull a named subsystem out as standalone EN w
- `render`: SVG or PNG diagram. Only call when user explicitly asks to visualize. The rendered image is delivered to the user, not injected into the model's context. See the server instructions for EN language syntax.
