Claude Skills

Get Codex's code review of git changes after Claude makes edits. Trigger when user wants a second opinion on code changes ("have Codex review my changes", "get code review from Codex", "review this diff with Codex"), or as a final check before committing.

Review Go code for adherence to Go Style Guide. Use when the user requests a code review of completed work, pull requests, or feature branches in Go projects. Focuses on critical bugs, race conditions, and important maintainability issues. Trigger phrases include "review this Go code", "check against style guide", "review my PR", or "review the work done so far".

Codebase analysis using Codex CLI with read-only sandbox. Trigger when user needs architecture overview ("analyze this codebase with Codex", "have Codex map dependencies"), onboarding to unfamiliar code, understanding legacy systems, or identifying technical debt.

GitHub issue management using GitHub CLI. Trigger when user wants to list issues ("show open issues"), view issue details ("view issue 456"), create issues ("create an issue", "file a bug"), or edit/close issues ("close issue", "add label to issue").

GitHub Actions workflow management using GitHub CLI. Trigger when user wants to check CI status ("check CI", "is the build passing"), view workflow runs ("show recent runs", "view action logs"), watch running workflows ("watch CI"), or rerun failed workflows ("rerun the build").

Fetch raw file content from GitHub URLs. Trigger when user shares a GitHub file link (https://github.com/user/repo/blob/main/file.go) and wants to view the source code. Avoids HTML/JS clutter from WebFetch.

Repository information using GitHub CLI. Trigger when user wants to view repository details ("show repo info", "what's this repo about"), list repositories ("list my repos", "show repos for user"), or check repository metadata ("stars", "languages", "topics").

On-demand access to Apple Developer Documentation via the apple-docs-mcp server. Triggers when users ask about SwiftUI, UIKit, iOS, macOS, watchOS, tvOS, visionOS, Swift, Xcode, WWDC, Apple APIs, or Apple frameworks.

Generate comprehensive test plans, manual test cases, regression test suites, and bug reports for QA engineers. Includes Figma MCP integration for design validation.

Use to audit test quality with Google Fellow SRE scrutiny - identifies tautological tests, coverage gaming, weak assertions, missing corner cases. Creates bd epic with tasks for improvements, then runs SRE task refinement on each.

Interactive math teacher that instantly generates playful, gamified learning experiences. Creates visual playgrounds, interactive artifacts, and engaging games for kids and adults to learn math concepts from basic arithmetic to advanced calculus.

Use when creating Claude Code hooks - covers hook patterns, composition, testing, progressive enhancement from simple to advanced

Generate comprehensive trading plans with risk management, position sizing, entry/exit strategies, and performance tracking to trade with discipline and consistency.

Generate comprehensive design briefs for design projects. Use this skill when designers ask to "create a design brief", "structure a design project", "define design requirements", or need help planning design work.

Use when facing 3+ independent failures that can be investigated without shared state or dependencies - dispatches multiple Claude agents to investigate and fix independent problems concurrently

Use when errors occur deep in execution - traces bugs backward through call stack to find original trigger, not just symptom

Use when writing or changing tests, adding mocks - prevents testing mock behavior, production pollution with test-only methods, and mocking without understanding dependencies

Use when encountering bugs or test failures - systematic debugging using debuggers, internet research, and agents to find root cause before fixing

Use when implementing features or fixing bugs - enforces RED-GREEN-REFACTOR cycle requiring tests to fail before writing code

Use when skills aren't activating reliably - covers official solutions (better descriptions) and custom hook system for deterministic skill activation

Use for advanced bd operations - splitting tasks mid-flight, merging duplicates, changing dependencies, archiving epics, querying metrics, cross-epic dependencies

Use to expand bd tasks with detailed implementation steps - adds exact file paths, complete code, verification commands assuming zero context

Use when refactoring code - test-preserving transformations in small steps, running tests between each change

Use when implementation complete and tests pass - closes bd epic, presents integration options (merge/PR/keep/discard), executes choice
