Create a new target implementation for universal-ai-config. A target maps universal template frontmatter and hooks to a specific AI coding assistant's configuration format.

Phase 1 — Research & Approval

1. Research the target's config format — find up-to-date documentation online for how the target AI assistant expects its configuration files. Look for:

   • File locations and naming conventions (e.g., .cursor/rules/*.mdc, .github/instructions/*.md)
   • Frontmatter format for each file type
   • Hook configuration format (JSON structure, event names)

   Look through docs for all supported configuration types:

   • Instructions/rules/"system prompt"
   • Skills/Commands
   • Agents
   • Hooks

2. Present findings for approval — before writing any code, present a structured summary of your research to the user. For each supported configuration type, include:

   • What it maps to: the universal template type it corresponds to (instructions, skills, agents, hooks)
   • File location & naming: where the target expects these files and what extensions/naming conventions it uses
   • Frontmatter/metadata format: the exact fields, keys, and structure the target uses (with examples from docs)
   • Hook format (if applicable): event names, JSON structure, how handlers are defined
   • Source links: direct URLs to the official documentation pages you referenced

   Format as a clear table or grouped list so the user can review each mapping. Ask the user to approve or flag any corrections before proceeding. Do not continue until the user explicitly approves.

Phase 2 — Plan

After the user approves the research findings, enter plan mode to design the full implementation before writing any code. The plan should cover:

3. Review existing targets for patterns — read through at least one existing target implementation (e.g., src/targets/claude/index.ts) and the shared types to understand the exact interfaces and conventions you need to follow.

4. Draft the implementation plan — produce a detailed, step-by-step plan that includes:

   • Target definition: the full defineTarget() structure — name, outputDir, supportedTypes, and for each supported type:
     • frontmatterMap — every universal key and what it maps to (string rename or function transform), with reasoning
     • getOutputPath — the exact path logic, including how alwaysApply or other flags affect routing
   • Hooks (if supported): transform function logic mapping universal event names → target events, outputPath, and mergeKey if the hook config nests inside a larger file
   • Registration: changes needed in src/targets/index.ts and the Target type in src/types.ts
   • Config schema: any changes needed in src/config/schema.ts or src/config/defaults.ts
   • Tests: which fixture(s) to use or create, and what assertions to write
   • Docs: any updates needed to README, meta-instruction templates, or seed files

   Reference the defineTarget() pattern:

   import { defineTarget } from "../define-target.js";
   import type { UniversalFrontmatter, UniversalHookHandler } from "../../types.js";
   
   export default defineTarget({
     name: "<target-name>",
     : ,
     : [, , , ],
     : {
       : {
         : ,
         : ,
         : ,
       },
       :  ,
     },
     
     
   });
   

Phase 3 — Implementation

Once the plan is approved, execute it:

6. Create the target directory — create src/targets/<name>/index.ts

7. Implement defineTarget() — follow the approved plan to build the full target definition

8. Register the target — add to src/targets/index.ts and the Target type in src/types.ts

9. Add tests — create integration tests using existing fixtures that generate for the new target, verifying output paths and content

10. Run pnpm check to verify everything passes
