Use Strata, the Legacy Code Labs macOS visual-spec app, through its local Streamable HTTP MCP server. Trigger when Codex needs to create, read, validate, update, version, diff, or restore Strata diagrams; build visual specs from user flows, discovery trees, architecture sketches, or D2; diagnose Strata MCP setup; or verify a feature against a shared Strata canvas.
Use Clarity, the LegacyCodeHQ structural design CLI, for dependency impact graphs, architecture/refactoring verification, before-commit design checks, code review context, cycle/module/workspace exploration, AGENTS.md Clarity setup, or rebuilding/probing Clarity command availability. Use when Codex needs to run or interpret clarity show, watch, languages, extensions, modules, cycles, workspace, setup, or version-specific Clarity commands.
Plan, build, harden, and review Kotlin backend services with Spring Boot, Ktor, coroutines, typed configuration, persistence, migrations, testing, security, resilience, and operations. Use for Kotlin HTTP APIs, workers, service refactors, production-readiness reviews, or JVM backend architecture decisions.
Reliability-first Kotlin skill for implementing, refactoring, or reviewing Kotlin libraries, CLIs, JVM modules, shared domain code, coroutine code, and Java interop boundaries. Use when work needs null-safety discipline, value and sealed types, idiomatic scope-function use, typed errors, structured concurrency, testing, or JVM quality gates.
Reliability-first Python skill for implementing, refactoring, or reviewing Python packages, CLIs, services, scripts, async code, tests, and typed modules. Use when work needs type hints, dataclasses, boundary parsing, exception design, context managers, asyncio cancellation, packaging, pytest or unittest strategy, ruff, mypy, pyright, or runtime safety.
Analyze images using local Ollama vision model (qwen3.5:4b) with automatic pre-resizing and filename sanitization for reliable processing.
Save the most recent visible conversation text from the active Codex thread into a timestamped Markdown checkpoint file in the current repo root. Use when the user asks to back up the last few chat messages, dump recent thread context to disk, preserve a resume point before context loss, or create a lightweight conversation recovery file.
Unify executable specifications, Tauri-first reliability, and Rust/Tauri architecture for desktop apps with a Rust backend and web frontend. Use when Codex needs to convert Tauri requests into REQ-TAURI contracts, choose command/state/capability/lifecycle boundaries, apply typed error and async safety patterns, select verification strategy, scope permissions and sidecars safely, or produce implementation plans and quality gates for Tauri 2 applications.
