Claude-oriented wrapper for mdht engineering tasks and repo-local skill packaging. Use when working on mdht with Claude and when preparing the repository skill pack for Claude compatibility.

Codex-oriented wrapper for mdht engineering tasks. Use when operating on this repository with Codex to apply mdht-core rules, command conventions, and strict module boundary checks.

Build and maintain mdht using strict hexagonal architecture per module (adapter-in to usecase to service to port-out to adapter-out). Use when adding commands, module features, vault markdown handling, SQLite projections, plugin runtime checks, TUI updates, or architecture/test enforcement in this repository.

Query the Context Engineering System for organizational knowledge including ADRs (architectural decisions), failure incidents, meeting decisions, and git snapshots. Use this skill when you need to understand past decisions, known issues, or recent changes before implementing features or making decisions.

Record architectural decisions (ADRs), failure incidents, meeting decisions, and deployment snapshots in the Context Engineering System. Use this skill when you make decisions, encounter errors, or participate in planning discussions.

Install and integrate the ShapeShifter Go middleware library in existing Go HTTP APIs. Use when adding contract-version JSON request/response transformation, authoring shapeshifter.yaml specs, mounting Echo/Gin/Chi/Fiber middleware, enabling the preview API or embedded contract portal, registering handlers, or debugging ShapeShifter integration in a Go repo.

Help users build and retain a working theory of their codebase during AI-assisted coding. Use when writing, modifying, reviewing, debugging, explaining, onboarding, or documenting code, especially for nontrivial changes, unfamiliar modules, maintainability work, ADRs, DECISIONS.md, or CLAUDE.md.
