Development

Safe procedure for decomposing a god file (400+ LOC) into a sub-package without breaking any imports. Load when a file exceeds 400 lines or mixes multiple concerns. Implements vibecodex Principles A1 and A8 — folder-instead-of-file with backward-compatible re-exports.

Pre-flight checklist that must complete before writing the first line of code for any new feature. Load this skill when starting a new endpoint, service method, or integration. Prevents the most common AI-coding failure mode — writing code before defining layer boundaries, which leads to features that work today and break in 3 months.

Pre-flight checklist for adding a new feature to a Next.js 15 + TypeScript app. Load when creating a new page, route, server action, or feature module. Forces feature-driven colocation, RSC-first thinking, and the typed cache-tag pattern from line one — prevents the most common AI failures (1500-line page.tsx, 'use client' on the layout, scattered revalidateTag magic strings).

Pre-flight checklist for adding a new feature to a Go 1.22+ service. Load when creating a new endpoint, internal package, external integration, or background worker. Forces "accept interfaces, return structs", `context.Context` propagation, error wrapping, and bulkhead-per-provider from line one — prevents the most common AI failures (God interfaces, raw goroutines without errgroup, http.DefaultClient everywhere, panic on errors).

Systematic 5-step debugging flow for Go 1.22+ services. Load when a test fails, a goroutine leaks, a downstream provider hangs, errors lose context, or production logs are unhelpful. Forces layer isolation (handler vs service vs repo vs provider) and runs the 5 most common Go antipattern greps before any code change — prevents the "add a goroutine to fix a slow handler" cascade.

Systematic 5-step debugging flow for Next.js 15 + React 19 + TypeScript apps. Load when a UI bug is reported, hydration error appears, Server Action returns wrong data, or cache invalidation fails. Forces layer isolation (server vs client, action vs component, cache vs render) before touching code — prevents "fix here, break there" cascades.

Systematic 5-step backend debugging flow for AI-coded FastAPI apps. Load this skill when a bug is reported, a test fails, or unexpected behavior appears in any backend layer. Forces layer isolation before touching code — prevents the "touch 8 files and make it worse" pattern.

Checklist for adding a new AI provider (image, video, text, audio) that satisfies all 5 integration principles — ACL, bulkhead, idempotency, observability, and contract test. Load when integrating any new external AI API. Prevents the most common mistake of pasting httpx calls directly into a service.

Defines the testing standards, patterns, and conventions for all C# unit and integration test projects. Rules cover test framework usage, naming, structure, mocking, assertions, and parameterization. Apply these rules uniformly across all test projects.

Defines the C# coding standards, patterns, and conventions to be applied consistently across all C# projects. Rules cover naming, structure, async patterns, null handling, dependency injection, logging, result patterns, and formatting. Apply these rules uniformly in all production code.

Defines the coding standards, patterns, and conventions for ASP.NET Core REST API controllers. Rules cover routing, HTTP verbs, response types, XML documentation, dependency injection, and asynchronous execution. Apply these rules uniformly to ensure a consistent, predictable, and well-documented API surface.

Scan a target codebase for API definitions (OpenAPI, REST routes, GraphQL schemas) and propose api_contract and api_endpoint registry entries. Presents findings for review before writing files.

Build or update the code review knowledge graph. Run this first to initialize, or let hooks keep it updated automatically.

Migrate a repo's GSD (.planning/) data to Linear issues. Use this skill when the user wants to transition from GSD to Linear, move planning data to Linear, import GSD phases into Linear, or asks about migrating their .planning/ directory. Also triggers on "migrate to linear", "move GSD to linear", "import planning to linear", or any mention of converting GSD phases/plans into Linear issues. Only relevant for repos that have a .planning/ directory.
