Rive Script Builder

Build Rive Luau scripts with a strict clarification-first workflow.

Knowledge policy:

• Prefer Context7 MCP lookup first (library: /rive-app/rive-docs).
• If Context7 is unavailable, fall back to sync_rive_docs.py online/cache/offline chain.
• Never invent APIs, lifecycle methods, or editor menus.

Non-Negotiable Contract

1. Parse user goal and recommend protocol(s) first.
2. Ask only high-impact unresolved questions.
3. Provide a “pending implementation plan” before writing code.
4. Wait for explicit approval (for example: “同意”, “开始写”, “approved”, “go ahead”).
5. After approval, output:

• Luau script code
• Rive editor wiring steps
• Debug and test suggestions

6. Follow the user’s language automatically.
7. If approval is missing, do not output final script code.

Workflow

Phase 0: Live Docs Lookup (Default)

Default lookup order:

1. Context7 MCP (primary)
2. scripts/sync_rive_docs.py (secondary fallback)

Context7 MCP primary call:

resolve-library-id -> /rive-app/rive-docs
query-docs(libraryId="/rive-app/rive-docs", query="<target API/protocol question>")

Query templates:

• docs/context7-query-recipes.md

Fallback lookup commands:

python3 "$CODEX_HOME/skills/rive-script-builder/scripts/sync_rive_docs.py" search --source auto --query "PathEffect"
python3 "$CODEX_HOME/skills/rive-script-builder/scripts/sync_rive_docs.py" show --source auto --path scripting/protocols/path-effect-scripts.mdx

Optional cache prewarm (recommended, not required):

python3 "$CODEX_HOME/skills/rive-script-builder/scripts/sync_rive_docs.py" sync

auto fallback chain:

• search: online -> cache -> offline
• show: online -> cache

If fallback happens, keep the reason explicit in output. See docs/live-docs-workflow.md. Offline knowledge includes full upstream mirror at docs/source-scripting/.

Phase 1: Scope and Route

• Identify target protocol using docs/protocol-router.md.
• Use docs/api-signature-cheatsheet.md to lock exact method signatures.
• If exact API details are ambiguous, check matching files in docs/source-scripting/api-reference/.
• For data-driven scripts, align with docs/data-binding-deep-dive.md and docs/script-inputs-deep-dive.md.
• If multiple protocols are needed, propose the smallest viable combination and explain why.
• State assumptions explicitly.

Phase 2: Clarify Uncertainty

• Ask only questions that change implementation decisions.
• Use docs/clarification-checklists.md.
• For interaction-heavy requests, use docs/pointer-events-playbook.md to narrow unresolved event-routing details.
• Skip questions already answered by user context.

Phase 3: Present Pending Plan

Present this structure before coding:

• Goal understanding
• Recommended protocol(s) and rationale
• Assumptions and constraints
• Implementation outline (functions, inputs, data flow)
• Rive wiring steps
• Debug and test plan
• Explicit confirmation request

If user does not approve, keep refining plan only.

Phase 4: Implement After Approval

• Generate minimal, runnable, typed Luau script first.
• Extend with requested behavior only.
• Reuse templates from references/scaffold-templates.md.
• For common tasks, start from references/case-recipes.md and adapt.
• Keep protocol lifecycle contracts valid.

Phase 5: Deliver With Integration Guidance

Always include:

• Final Luau code
• Editor wiring instructions (where to attach, bind, and run)
• Debug checklist (Problems and Console)
• Test suggestions (especially Test scripts for Util logic)

Use docs/editor-wiring-recipes.md and docs/debug-test-playbook.md. Use docs/path-api-performance-notes.md for path-heavy scripts. Use docs/quality-gates.md as final quality checklist.

Protocol and API Guardrails

• Never invent lifecycle functions, interfaces, or editor paths.
• Keep TransitionCondition.evaluate fast and side-effect free.
• Use ListenerAction.perform for side effects.
• For PathEffect, keep update deterministic; use advance only for time-based behavior.
• Remember: scripts cannot set normal input values; use context or view model access for writable data.
• Remove long-lived listeners when no longer needed to avoid leaks.
• Check docs/common-errors-and-fixes.md before final handoff.
• If required details are missing, ask before coding.

Output Format

Before approval:

• Understanding
• Open questions
• Pending plan
• Confirmation prompt

After approval:

• Script code
• Wiring steps
• Debug plan
• Test plan
