Skill Claude CodeCodex
Streamline session-to-session coordination with the intercom extension. Send messages, delegate tasks, and coordinate work across multiple atomic sessions on the same machine. Use for planner-worker workflows, cross-session context sharing, and real-time collaboration between sessions.
Agent
Clean up, simplify, or refine recently written or modified code without changing behavior. Improves readability, removes duplication, clarifies naming, tightens control flow, and aligns with project conventions. Reads the code as a set of doors — the entrypoints where intent lives — and works to make those boundaries…
Agent
Analyzes codebase implementation details. Call the codebase-analyzer agent when you need to find detailed information about specific components.
Agent
Locates files, directories, and components relevant to a feature or task. Basically a "super search/find/ls tool.".
Agent
Online research for up-to-date documentation and library-source knowledge. Use when you need authoritative external information — official docs, ecosystem context, version-specific behavior, GitHub permalinks into open-source libraries, or video tutorials.
Agent
Find similar implementations, usage examples, or existing patterns in the codebase that can be modeled after.
Agent
Analyzes local research documents to extract high-value insights, decisions, and technical details while filtering out noise. Use this when you want to deep dive on a research topic or understand the rationale behind decisions.
Agent
Discovers local research documents that are relevant to the current research task.
Agent
Debug and fix errors, test failures, and unexpected behavior. Use PROACTIVELY when encountering issues, analyzing stack traces, or investigating system problems.
Skill Claude CodeCodex
Use this skill whenever a task involves a document file (PDF, DOCX, PPTX, XLSX, or image) and you need to read it or pull text, tables, or specific values out of it — to answer a question about its contents, look up a figure, or extract data. Provides fast, local, model-free extraction via the lit CLI with…
Skill Claude CodeCodex
Automate browser interactions, test web pages and work with Playwright tests.
Skill Claude CodeCodex
Code quality checks, formatting, and metrics via qlty CLI. Use when asked to verify code quality, add or run verifiers, make sure code is high quality before commit or handoff, lint or auto-format a codebase, measure complexity, cohesion, or lines of code, or find code smells like duplication and deep nesting.
Skill Claude CodeCodex
Delegate work to builtin or custom subagents with single-agent, parallel, forked-context, and intercom-coordinated runs. Use for bounded specialist delegation where a single parent agent stays in control while subagents contribute locate, analyze, pattern-find, research, debug, or simplify passes.
Skill Claude CodeCodex
Test-driven development with red-green-refactor loop. Use when user wants to build features or fix bugs using TDD, mentions "red-green-refactor", wants integration tests, or asks for test-first development.
Skill Claude CodeCodex
Control tmux-compatible sessions/windows/panes for interactive CLIs: list, capture output, send keys, paste text, monitor prompts.
Skill Claude CodeCodex
Restate the last message in plain human language, with no jargon.
Skill Claude CodeCodex
Create a detailed execution plan/spec/PRD for implementing features or refactors in a codebase, designed around the program's entrypoints, the doors that carry domain intent, by leveraging existing research in the codebase.
