Automated summary
Migrates a complete module to a target architecture following a 6-phase process with validation and approval gates in between.
Strengths
- Structured and repeatable process with clear phases
- Validation after each phase (build, svelte-check, tests)
- Comprehensive coverage from analysis to final review
Limitations
- Requires the target architecture to be defined in docs/ARCHITECTURE.md
- Does not handle external dependencies or complex integrations
- Approval phases can slow down automated execution
Use this skill when you need to migrate an entire module (files, types, services, state, components) to a new architecture.
Do not use it for small changes or partial refactors, as the process is designed for a complete and systematic migration.
Security analysis
CautionThe skill uses Bash for standard development validation steps. There is no instruction to run destructive or exfiltrating commands, and each phase requires user approval, mitigating risk. However, the presence of Bash execution warrants caution.
- •Uses Bash tool, which could execute arbitrary commands, though here it is limited to running build/lint/test commands like svelte-check, npm run build, npm test.
- •The skill is user-invocable and takes an external argument (module path) without validation, but the commands are predefined.
Examples
Migrate the user module at src/lib/modules/user to the target architecture defined in docs/ARCHITECTURE.md.Run the migration skill for the payment module located in src/lib/modules/payment.name: migration-migrate-module description: "Use when a complete module needs migration to the target architecture - runs 6 phases with approval gates." user-invocable: true argument-hint: "[module-path]" allowed-tools: Read, Write, Edit, Bash, Glob, Grep
Migrate an entire module to the target architecture from docs/ARCHITECTURE.md.

Steps
Use @migrator to coordinate the full migration in phases:
- Phase 0 -- Analysis: Map the module (files, Svelte 4 vs 5 patterns, JS vs TS, SvelteKit 1 vs 2 patterns, dependencies)
- Phase 1 -- Structure: Create
src/lib/modules/[name]/and route files, move existing files - Phase 2 -- Types: Create
.types.ts+.contracts.ts+ adapter - Phase 3 -- Services: Migrate to pure service (no try/catch, native fetch)
- Phase 4 -- State: Server state -> SvelteKit load functions, Client state -> Svelte stores
- Phase 5 -- Components: Svelte 4 -> 5 runes + composition (see conversion table)
- Phase 6 -- Review: Validate conformance, check for remaining legacy patterns
Validate build/svelte-check/tests after each phase. Ask for approval before each phase.
From the file to a first result
The download contains exactly the content displayed on this page. This copy may differ from the latest version in the source repository.
View the source and supporting filesThis download contains SKILL.md only. Any scripts, references, templates and dependencies are not included. Get the required files from the source, preserving their directory structure, before continuing.
1. Download the file
Download SKILL.mdFrom the root of a test project, save the file as .skill-downloads/module-migration-to-target-architecture-mm8o528h/SKILL.md, or use the command below. This folder is for inspecting the skill before installation.
Command for macOS/Linux or WSL: requires a POSIX shell and curl. On Windows without WSL, use the download button and create the folder manually.
mkdir -p '.skill-downloads/module-migration-to-target-architecture-mm8o528h' && curl --fail --show-error --location 'https://skills-guides.com/api/skills/module-migration-to-target-architecture-mm8o528h/download' --output '.skill-downloads/module-migration-to-target-architecture-mm8o528h/SKILL.md.part' && mv '.skill-downloads/module-migration-to-target-architecture-mm8o528h/SKILL.md.part' '.skill-downloads/module-migration-to-target-architecture-mm8o528h/SKILL.md'2. Check prerequisites
Read SKILL.md before using it. If it references scripts or external services, inspect them and prepare the required access in your test environment.
Tools declared by the author (check availability in your agent): Read, Write, Edit, Bash, Glob, Grep
No recognized prerequisites section in this file. This does not mean it is self-contained: libraries, tools and access requirements may be mentioned elsewhere in the content or source repository.
The platforms on this page are catalog indications. The paths below follow tool documentation; they do not prove this skill has been run in those tools. No minimum tool version is confirmed for this listing.
3. Load the skill
After inspection, copy the complete folder into your project using one of the commands below, then open a new tool session. The command stops if a folder with the same name already exists: compare the files before replacing it.

OpenSkills must already be installed. The local install/read procedure is checked with OpenSkills 1.5.0, which requires Node.js ≥ 20.6.0. Catalog slugs are not resolved automatically.

It does not run the skill or install its dependencies.
For an agent that reads AGENTS.md, then sync the index. This command changes AGENTS.md: review the diff before using it.
openskills syncManual method or another tool: attach SKILL.md to a conversation, or open it in an agent that can read files. Include any required supporting resources. No universal folder is recognized by every tool.
4. Try a first task
Use a short, synthetic input: an API endpoint, a small document or an interface brief. In a new conversation, attach the file or give the agent its path, then adapt this request:
Read .skill-downloads/module-migration-to-target-architecture-mm8o528h/SKILL.md and apply its instructions to this example: [describe a test input]. Identify any missing files, dependencies or access. Produce the result requested by the skill without inventing data or running unreviewed scripts.Expected result: output matching the skill instructions, or a precise list of missing prerequisites. A read confirmation alone does not validate a first use. If an external resource is unavailable, that path remains untested.
React Hook Form Best Practices
Development
Master React Hook Form: avoid anti-patterns, manage subscriptions, and handle reset, dirty state, and controlled inputs correctly.
Emotion to Mantine Migration
Development
Migrate Emotion styled-components to Mantine components with style props and CSS modules. Use when converting .styled.tsx files or removing @emotion imports.
Scope Creep Detector
Development
Analyzes git diffs against a stated intent to detect scope creep, unrelated files, broad PRs, and oversized changes, then suggests keep, split, or justify actions.
