Proposed Keyword Mappings + +### 2.1 Control Flow Keywords + +#### Selector Node +**Current:** `? { ... }` +**Proposed:** `selector { ... }` OR `choose { ... }` + +**Rationale:** "Choose" is more storytelling-friendly. "Selector" is technically accurate for developers. + +**Recommendation:** Support both, with `choose` as the preferred form in examples. (i want `choose`, no `selector`) + +**Example:** +```sb +// Before +? { + try_option_a + try_option_b + fallback +} + +// After (storyteller-friendly) +choose { + try_option_a + try_option_b + fallback +} + +// After (developer-friendly) +selector { + try_option_a + try_option_b + fallback +} +``` + +#### Sequence Node +**Current:** `> { ... }` +**Proposed:** `sequence { ... }` OR `then { ... }` + +**Rationale:** "Then" reads naturally in storytelling contexts. "Sequence" is technically precise. + +**Recommendation:** Support both, with context determining preference. (i want `then`, no `sequence`) + +**Example:** +```sb +// Before +> { + check_energy + move_to_location + perform_action +} + +// After (storyteller-friendly) +then { + check_energy + move_to_location + perform_action +} + +// After (developer-friendly) +sequence { + check_energy + move_to_location + perform_action +} +``` + +### 2.2 Condition Keywords + +**Current:** `! expression` +**Proposed:** `if(expression)` OR `when(expression)` + +**Rationale:** Clear, universally understood conditional syntax. + +**Recommendation:** Support both for flexibility. `when` is more narrative-friendly. (use `when`) + +**Example:** +```sb +// Before +! need.any is urgent + +// After (either form) +if(need.any is urgent) +when(need.any is urgent) +``` + +### 2.3 Action Keywords + +**Current:** `@ action_name` or `@ action_name(params)` +**Proposed:** Remove prefix, just use action name + +**Rationale:** Actions are distinguishable from control flow by context. No prefix needed. (yeah i'm fine with this) + +**Example:** +```sb +// Before +@ move_to(counter) +@ serve_next_customer + +// After +move_to(counter) +serve_next_customer +``` + +### 2.4 Subtree Keywords + +**Current:** `@path::to::subtree` +**Proposed:** `include path::to::subtree` + +**Rationale:** "Include" clearly indicates pulling in external definition.

Migration Strategy + +### 11.1 Breaking Changes + +**This is a BREAKING change that requires:** +1. All existing `.sb` files with behaviors to be updated +2. Tree-sitter grammar update +3. Parser update +4. Compiler update +5. SBIR version bump (likely 0.1.0 → 0.2.0) + +**Recommendation:** Since we're in early development (pre-1.0), make this change now before user base grows. + +### 11.2 Migration Path + +**Option A: Clean Break (Recommended)** +1. Implement new syntax +2. Migrate all examples manually +3. Update documentation +4. Deprecate old syntax entirely +5. Version bump to 0.2.0 + +**Option B: Dual Support (Not Recommended)** +1. Support both syntaxes during transition +2. Emit deprecation warnings for old syntax +3. Provide automated migration tool +4. Remove old syntax in 0.3.0 + +**Recommendation:** Option A.

Open Questions for User Review (Checkpoint 1) + +### Question 1: Priority vs. Declaration Order + +**Current Design:** Priority determines order, then declaration order breaks ties. + +**Alternative:** Remove priority, use only declaration order (simpler but less expressive). + +**Recommendation:** Keep priority. It's more explicit and handles common use cases like "urgent needs always trump routine activities." (i guess priority is fine) + +### Question 2: Condition Syntax Sugar + +**Current Design:** Full condition expressions. + +**Alternative:** Add syntactic sugar for common patterns: +```storybook +uses behaviors: [ + { tree: GiantBehavior, when: current_size == huge } + // vs. + { tree: GiantBehavior, when current_size: huge } // shorter +] +``` + +**Recommendation:** Start with full expressions, add sugar if usage reveals patterns. (use `==` or `is`, support both like python does.) + +### Question 3: Schedule-Behavior Integration + +**Current Design:** Behaviors and schedules are separate links. Schedule determines WHEN, behavior determines WHAT. + +**Alternative:** Allow schedules to specify behaviors inline: +```storybook +schedule WorkSchedule { + block work { 9:00 - 17:00, behavior: WorkBehavior } +} +``` + +**Recommendation:** Defer inline behaviors to schedule system design (Task #8). Keep linking separate for now. (yeah that's fine) + +### Question 4: Link Override Semantics + +**Current Design:** If character defines any behavior links, template's links are completely replaced. + +**Alternative:** Merge character and template links (character links come first, then template links). + +**Recommendation:** Keep replacement semantics. It's clearer and matches existing override system. (sure? i don't remember the nuances tbh) + +### Question 5: Multiple Defaults + +**Current Design:** At most one `default: true` per link type. + +**Alternative:** Allow multiple defaults with priority order. + +**Recommendation:** Keep single default. Multiple defaults creates ambiguity. (single default makes sense?) + +--- + +## 11. Implementation Plan (for Task #6) + +### Phase 1: AST Extension (Week 1) +1.
