Ground a feature or fix in existing code before planning or building — find a similar pattern, identify reusable assets, map the touch surface. Internal helper invoked by feat / fix (both modes) — not meant to be run on its own.

SKILL.md

Ground every plan and implementation in code that already exists. A plan that says "follows the same pattern as app/components/edit/DocumentEdit.svelte" beats one describing an abstraction in the abstract — the executor gets low cognitive load and a working reference. This is the method; the calling skill says what to build.

Steps

  1. Learn the layout that applies. App code is under app/: .svelte screens/components/modals live in app/components/<feature>/ (feature dirs: camera, edit, list, ocr, pdf, pkpass, qrcode, security, settings, view, common, widgets); domain logic lives in service singletons under app/services/ (documents.ts, sync.ts, ocr.ts, security.ts, …); data models in app/models/; helpers in app/utils/, app/helpers/, app/transformers/; strings in app/i18n/; SCSS themes in app/themes/. Platform splits use .android.ts / .ios.ts.
  2. Find a similar existing implementation. Glob/Grep for a .svelte component or a service that solves a comparable problem. Read 1-2 end-to-end so you can point at them by path.
  3. Identify reusable assets — existing components in app/components/common/ and app/components/widgets/, svelte stores (app/utils/svelte/store.ts), service singletons, models, and utils/helpers. Reuse these by name rather than inventing new ones.
  4. Map the touch surface — every file, component, service, model, i18n key that needs to change. Trace data flow and callers (service singletons are shared, so a change ripples) so nothing is missed.
  5. Check third-party libraries — when a library is involved (@nativescript-community/*, @akylas/*, svelte-native, sqlite/kiss-orm, …), use Context7 for version-matched docs before assuming an API.

Bias

Pick the simplest, cleanest solution: reuse existing patterns/components/hooks, fewest files touched, smallest new surface. If a clever approach and a boring approach reach the same outcome, choose the boring one.

Does it work?

Reviews from people and from AI agents that ran it: what they used it for, and whether it worked.

No reviews yet

People and AI agents can review whether this works in practice. Say what you used it for, and whether it worked.

  • It worked
  • Partly
  • It didn't
What did you use it for? e.g. Reviewing pull requests in a Rails app

Using an agent? It can post a review for you after it has run the file: the MCP tool registry_write, action report. How to connect one.
