Default structured reasoning. Decomposes problems into atomic thoughts with dependency tracking. Depth 3.

Use for: think-through, analyze, reason about tradeoffs, debug root causes, evaluate alternatives, make decisions. Most reasoning tasks belong here.

Trigger phrases: "think through", "analyze", "reason about", "debug", "evaluate options", "compare approaches".

Atom types: premise (facts) → reasoning (logic) → hypothesis (proposals) → verification (checks) → conclusion (answer).

Minimal 3-call example: Call 1: {atomId:"P1", content:"The API returns 500 on POST /users", atomType:"premise"} Call 2: {atomId:"R1", content:"500 suggests unhandled exception in route handler", atomType:"reasoning", dependencies:["P1"]} Call 3: {atomId:"C1", content:"Add try-catch in POST /users handler", atomType:"conclusion", dependencies:["R1"], confidence:0.9}

Only atomId, content, and atomType are required. dependencies defaults to [], confidence defaults to 0.7.

Use AoT-full instead when you need >5 reasoning steps, multi-angle verification, or decomposition of sub-problems.

viz param: only set viz:true when the user explicitly asks to see the graph or says "visualize". Never set it automatically.

Deep structured reasoning with decomposition-contraction. Depth 5.

Use for: implementation plans, architecture decisions, multi-step verification, problems that decompose into sub-problems.

Trigger phrases: "plan", "design", "megathink", "full AoT", /aot-plan.

Same atom types and parameters as AoT-fast. Drives decomposition via the atomcommands tool (decompose → sub-atoms → complete_decomposition). Reach for AoT-fast first unless you genuinely need the extra depth or decomposition.

viz param: only set viz:true when the user explicitly asks to see the graph or says "visualize". Never set it automatically.

Lifecycle and meta operations for the current AoT session.

Commands:

• decompose: Break an atom into sub-atoms (requires atomId)

• complete_decomposition: Finish a decomposition (requires decompositionId)

• termination_status: Check if reasoning should stop

• best_conclusion: Get the highest-confidence verified conclusion

• set_max_depth: Change max depth limit (requires maxDepth)

• export: Export the current atom graph as JSON for analysis or visualization (optional title)

• check_approval: Poll for browser-based approval decisions (optional downloadsDir, sessionStartTime)

• new_session: Create and switch to a new session (optional sessionId; auto-generated if omitted)

• switch_session: Activate an existing session (requires sessionId)

• list_sessions: List all sessions with status and atom counts

• reset_session: Wipe atoms in a session (defaults to active)
