- ▌ Hotspots · lexler bundleFind where a codebase actually costs time by mining its git history (Tornhill hotspot analysis). Produces ranked refactoring targets with evidence, change-coupling seams, and a do-not-refactor list; re-run after refactoring to verify it paid off.
- ▌ Extract Knowledge · lexlerExtracts what the session learned into prose that stands alone, or reviews existing text through the same distortion lenses.
- ▌
- ▌ Refactoring · lexler bundleRefactoring process. Invoke immediately when user or document mentions refactoring, or proactively when code gets too complex or messy.
- ▌ Approval Tests · lexler bundleWrites approval tests (snapshot/golden master testing) for Python, JavaScript/TypeScript, or Java. Use when verifying complex output, characterization testing legacy code, testing combinations, or working with .approved/.received files.
- ▌ Tdd · lexler bundleTest-driven development (TDD) process used when writing code. Use whenever you are adding any new code, unless the user explicitly asks to skip TDD or the code is exploratory/spike.
- ▌ Align · lexlerPresents a proposed approach in progressive confirmable chunks with recommended decisions and alternatives. Use when aligning on a design, plan, or technical approach before implementation.
- ▌ AI Patterns · lexler bundleReference patterns for augmented coding with AI. Use when discussing AI coding patterns, anti-patterns, obstacles, context management, steering AI, or looking up Lexler's patterns collection.
- ▌ Nullables · lexler bundleNullables — testing technique alternative to using mocking libraries. Use when writing unit tests, when code touches external I/O or state (HTTP, databases, files, clock, random) anywhere in its dependency chain, when making a system testable, or when tests are slow or flaky.
- ▌ C4 Diagrams · lexler bundleCreates C4 architecture diagrams for designing, documenting, or understanding software architecture. Use when working through system design, mapping existing codebases, or visualizing structure at any level from system landscape down to code.
- ▌ Using Uv · lexler bundlePython package and project management with UV. Use when creating Python scripts, initializing projects, or managing dependencies.
- ▌ Creating Process Files · lexler bundleCreates process files - text as code instructions for reliable AI workflows. Use when creating new process files.
- ▌ Refinement Loop · lexlerIterative refinement through multiple passes. Use when the user asks to 'meditate on', 'distill', 'refine', or 'iterate on' something, or proactively when a problem benefits from multiple passes rather than a single attempt.
- ▌ Socratic Learning · lexler bundleFacilitates deep, structured learning of a topic — gathering source material, assessing the learner's gaps, then teaching through guided Socratic sessions. Use when someone wants to genuinely study or be tutored on a subject over time, not get a quick answer.
- ▌ Bdd With Approvals · lexler bundleScannable BDD tests written in domain language. Use when doing BDD.
- ▌ Collaborative Design · lexler bundleDesigns software features collaboratively through visual scenarios and iterative refinement. Use when designing features, tools, UIs, workflows, or any system before implementation.
- ▌
- ▌ Hexagonal Architecture · lexler bundleApplies hexagonal (ports & adapters) architecture. Use when designing application structure, separating domain from infrastructure, creating testable boundaries, or when user mentions ports, adapters, hexagonal, or clean architecture.
- ▌ Git Worktrees · lexlerCreates git worktrees for parallel development. Use when creating a git worktree, setting up multiple working directories, or working on features in parallel.
- ▌ Demo With Narration · lexlerDemos working software: first proves every claimed behavior by exercising the real artifact, then replays the proof as a slow, voice-narrated walkthrough. Use when the user asks for a demo or to be shown that something works.
- ▌ Playwright CLI · lexler bundleDrive a browser from the terminal with playwright-cli: snapshot the page, then act on elements by ref. Use when automating browser interactions, filling web forms, testing UIs, or driving logged-in web apps from the command line.
- ▌ Refactoring Team · lexler bundleIterative code refactoring through progressive lenses via a worker-reviewer agent team.
- ▌ Writing Statuslines · lexler bundleWrites Claude Code status line scripts. Use when creating, customizing, or debugging statusline configurations.
- ▌ Launching Agent Teams · lexler bundleLaunches agent teams with structured roles and task decomposition. Use when asked to create a team, spawn teammates, or coordinate multiple agents in parallel.
- ▌ Writing Bash Scripts · lexler bundleBash script style guide. Always use when writing bash scripts, shell scripts, or CLI bash tools.
- ▌ Growing Outside In Systems · lexler bundleDrive feature development using Outside-In TDD with Hexagonal Architecture. Design emerges through inline code, in-memory fakes, interface extraction, and deferred I/O. Use when building features, writing tests, or structuring backend services. Triggers on: TDD, outside-in, hexagonal, ports and adapters, emergent design, acceptance test, component test, walking skeleton, in-memory fakes, component, contract test, adapter, fast tests, sub-second feedback. Language-agnostic (Go, Rust, Python, TypeScript, Java, C#).
