Create polished Python terminal user interfaces and skill scripts with Textual and Rich. Use when: building TUI apps; adding interactive terminal workflows; designing tabs, progress bars, checkboxes, radio buttons, tables, charts, forms, status views, keyboard navigation, color, or responsive terminal layouts; making Python scripts visually appealing and informative. Every skill script defaults to a TUI on an interactive terminal and provides --no-tui for deterministic stream output. DO NOT USE FOR: browser GUIs; desktop-native GUIs; plain shell commands with no interactive workflow; non-Python applications.

Embed the GitHub Copilot agent runtime into your own application using the Copilot SDK. USE FOR: CopilotClient/createSession setup, streaming responses, custom tools, permission handlers, hooks (pre/post-tool-use, session-start), custom agents and sub-agent delegation, MCP servers, skill and plugin directories, session persistence, fleet mode, steering/queueing, calling the SDK from skill scripts/ to run one bounded non-deterministic AI step inside an otherwise deterministic script, and choosing an auth/deployment path (CLI setup, backend services, multi-tenancy, GitHub OAuth, BYOK). Covers Node.js/TypeScript (@github/copilot-sdk), Python (github-copilot-sdk), Go (github.com/github/copilot-sdk/go), Rust (github-copilot-sdk crate), .NET (GitHub.Copilot.SDK), and Java (copilot-sdk-java). DO NOT USE FOR: authoring SKILL.md files consumed by VS Code Copilot (use create-skill instead); using the Copilot IDE extension or chat UI directly; general LLM/chat API integration unrelated to the Copilot SDK.

Automate GitHub Copilot CLI in GitHub Actions workflows. USE FOR: installing/running `copilot -p` in workflow steps, choosing GITHUB_TOKEN vs a personal access token (COPILOT_GITHUB_TOKEN) for authentication, setting the copilot-requests write permission, minimal-permission tool allowlisting (--allow-tool, --deny-tool, --no-ask-user, -s/--silent, --output-format=json), triggers (schedule, workflow_dispatch, push), the recommended GitHub Agentic Workflows (gh-aw) alternative to direct CLI invocation, and security/cost considerations (fork PR prompt-injection risk, billing attribution, cost centers). DO NOT USE FOR: embedding the Copilot agent runtime into your own application (use copilot-sdk instead); general GitHub Actions authoring unrelated to Copilot; the Copilot code review or PR features outside of CLI automation.

Install, verify, and integrate codebase-memory-mcp (CBM) — a local C binary indexing a codebase into a persistent knowledge graph (functions, classes, call chains, routes) queryable via 15 tools. USE FOR: creating or editing any agent/skill/prompt/subagent that reads, searches, or reasons about a codebase — CBM's CLI must replace grep/ripgrep/glob-and-read exploration for structural questions (who calls X, dead code, architecture overview, diff impact, Cypher queries); checking whether `codebase-memory-mcp` is installed; installing/updating it; checking whether a project's index is fresh/in sync (`index_status`); choosing CLI vs MCP (always prefer the CLI, far fewer tokens per call than MCP); picking the right CBM tool per workflow stage (discovery, verification, implementation, review). DO NOT USE FOR: semantic/business-logic code review; non-code repos with nothing to index.
