motionspec
Verifies and compiles reduced-motion-safe, on-budget UI animation for AI-generated web apps: schema-validated specs to deterministic vanilla-GSAP + CSS, WCAG 2.2.2 / 2.3.3 checks. MIT core, keyless MCP server, free web check at motionspec.dev/motion-check. Not Motion.dev/Framer Motion, not the Android/iOS MotionSpec class, not a video generator.
Emerging. No concerning findings. Grades remain capped until the project builds reputation through adoption. Grades reflect the full trust pyramid: code, verification depth, and reputation. New projects cap at C until adoption is earned.

9 dependencies, 1 flagged: @playwright/test
All four hints declared on every tool
4/5 tools missing one or more hints — motion_catalog (missing: destructiveHint, idempotentHint); motion_validate (missing: destructiveHint, idempotentHint); motion_audit (missing: destructiveHint, idempotentHint), +1 more. OpenAI's directory rejects tools where any of the four hints are missing or non-boolean.
For every tool, set all four hints (readOnlyHint, destructiveHint, idempotentHint, openWorldHint) to explicit true/false values that match the handler’s actual behaviour.
Tool inputs are validated
3/5 tool handlers declare input schemas (60%)
Declare an inputSchema with zod/joi/yup on every tool definition.
Tool handlers catch errors
3/5 tool handlers wrap calls in try/catch (60%)
Wrap each tool handler body in try/catch and return a structured error response.
Tool test coverage
Only 1/5 tools referenced in tests (20%)
Write tests that reference each tool by name so every tool has at least one test.
Shell command execution
14 child_process calls — runs shell commands
Prefer library functions over shell-outs. If you must shell out, ensure all inputs are properly escaped.
