Turn a PRD into a multi-phase implementation plan using tracer-bullet vertical slices, saved as a local Markdown file in ./plans/. Use when user wants to break down a PRD, create an implementation plan, plan phases from a PRD, or mentions "tracer bullets".

Building a New Entry Wizard for the Headless CMS. Use this skill when the developer wants to show a custom wizard UI before the entry form when creating new CMS entries -- collecting fields like title, slug, or category upfront, then pre-filling the entry form. Covers ContentEntryEditorConfig.NewEntryWizard, createFeature, FormModelFactory, createReactiveComponent, useContentEntryFormPresenter, and the dirty-flag on setData.
Building forms with the FormModel system — field types, renderers, layout, validation, conditional rules, computed fields, and dynamic zones. Use this skill when the developer needs to define form fields with the builder API, choose renderers, build layouts with tabs/rows/separators, add validation (Zod or imperative), use conditional visibility/disable rules, create computed fields, or work with object fields and templates (dynamic zones).

Admin-side architecture patterns for Webiny extensions. Use this skill when building frontend features with headless features (UseCase/Repository/Gateway), presentation features (Presenter/ViewModel/hooks/components), MobX-based presenters, RegisterFeature, and Admin BuildParams. Covers the admin/ directory structure for both features/ and presentation/ layers.
Covers the PreviewUrlModifier extension point in Website Builder. Use when a user wants to inject custom query parameters into live preview URLs — e.g. signed tokens, tenant identifiers, feature flags — from their Webiny project. Handles the full registration pattern: implementing the interface, wiring via createFeature + RegisterFeature, and registering via webiny.config.tsx. Supports async modifier methods (e.g. remote token fetch).

Break a PRD into a phased implementation plan using vertical slices (tracer bullets). Output is a Markdown file in ./ai-context/plans/.
The PRD should already be in the conversation. If it isn't, ask the user to paste it or point you to the file.
If you have not already explored the codebase, do so to understand the current architecture, existing patterns, and integration layers.
Before slicing, identify high-level decisions that are unlikely to change throughout implementation:
These go in the plan header so every phase can reference them.
Break the PRD into tracer bullet phases. Each phase is a thin vertical slice that cuts through ALL integration layers end-to-end, NOT a horizontal slice of one layer.
- Each slice delivers a narrow but COMPLETE path through every layer (schema, API, UI, tests) - A completed slice is demoable or verifiable on its own - Prefer many thin slices over few thick ones - Do NOT include specific file names, function names, or implementation details that are likely to change as later phases are built - DO include durable decisions: route paths, schema shapes, data model namesPresent the proposed breakdown as a numbered list. For each phase show:
Ask the user:
Iterate until the user approves the breakdown.
Create ./plans/ if it doesn't exist. Write the plan as a Markdown file named after the feature (e.g. ./plans/user-onboarding.md). Use the template below.
