leta
Fast semantic code navigation via LSP. Load FIRST before ANY code task - even 'simple' ones. Trigger scenarios: (1) fixing lint/type/pyright/mypy warnings or errors, (2) fixing reportAny/reportUnknownType/Any type errors, (3) adding type annotations, (4) refactoring or modifying code, (5) finding where a function/class/symbol is defined, (6) finding where a symbol is used/referenced/imported, (7) understanding what a function calls or what calls it, (8) exploring unfamiliar code or understanding architecture, (9) renaming symbols across codebase, (10) finding interface/protocol implementations, (11) ANY task where you'd use ripgrep to find code or read-file to view a function. Use `leta show SYMBOL` instead of read-file, `leta refs SYMBOL` instead of ripgrep for usages, `leta grep PATTERN` instead of ripgrep for definitions, `leta files` instead of list-directory.

repo-explore
Clone and explore external GitHub repositories to understand how libraries, frameworks, or dependencies work. Use when user provides a GitHub URL (github.com/owner/repo), asks "how does X library work", wants to look at source code for a dependency, asks about implementation details of an external package, or says "explore", "look at", or "check out" a repository. Automatically checks out the matching version tag when the repo is a dependency in the current project.
socratic
Deep collaborative debate and research through exhaustive co-interview between Claude and Codex. Use when user wants extremely thorough analysis, needs to explore a problem from every angle, wants creative/unconventional questioning, says "get socratic", "debate this", "deep dive", "exhaustive analysis", "think through everything", "challenge all assumptions", or needs rigorous exploration before major decisions.
code-review
Orchestrates a three-phase parallel code review using an agent team. Phase 1: dynamically selected specialists each review the diff with structured self-critique. Phase 2: mandatory lead-mediated cross-review where specialists challenge each other's findings (primary rigor layer). Phase 3: deduplicated synthesis with priority-based output and binary merge verdict.
diataxis-documentation
Write comprehensive, user-focused documentation following the Diataxis framework. Use this skill when creating or improving tutorials, how-to guides, reference documentation, or explanatory content. Helps identify the right documentation type and apply best practices for each.
git-commit
