Turns CLAUDE.md into a router with a task-based routing table, consolidates context into a single knowledge directory, and cleans MEMORY.md into a pure index. Use when starting a new project, when CLAUDE.md has 'always read' directives, when context feels bloated, or when the user says /init-context.

tmux
Remote control tmux sessions for interactive CLIs (python, gdb, etc.) by sending keystrokes and scraping pane output.
eval-notebook
Execute .ipynb notebooks (Python, Kotlin, or any Jupyter kernel) without overwriting; return LLM-friendly JSON with outputs and errors. Use when you need to run or validate a Jupyter notebook.
adr-writing
Use when documenting significant architectural decisions. Creates focused ADRs explaining context, decision, and alternatives. Prevents vague documentation and implementation detail bloat. Triggers: 'create ADR', 'document decision', making technology/framework/persistence/auth choices, cross-cutting concerns.
bitbucket-pr
Read and manage Bitbucket Cloud pull requests, comments, and tasks via the `bb` CLI (gildas/bitbucket-cli v0.18.1+). Use when reviewing PR feedback, replying to comments, creating tasks/PRs, or marking review tasks done. Also bridges JIRA issues to their linked Bitbucket PRs/branches/repos via Jira's dev-status API — find the PR(s) for a JIRA key (e.g. VUKFZIF-1234), even in repos that aren't cloned locally.

electron-ui
Automate Electron desktop apps (VS Code, Slack, Discord, Microsoft Teams, Figma, Notion, Spotify, Obsidian, Linear, 1Password, …) by connecting to their Chrome DevTools Protocol port. Use when the user wants to control or test a native desktop app, or when the workflow needs CDP connect / --remote-debugging-port. Same snapshot + @eN ref workflow as web pages.
grafana
Manage Grafana dashboards, datasources, folders, alerting, and annotations via the HTTP API. Query datasources (PromQL, LogQL, TraceQL, SQL) and export results to Parquet, TSV, or JSONL. Use when creating, editing, or querying Grafana resources programmatically.

dendritic-nix
Applies the Dendritic Pattern for structuring Nix flake configurations with flake-parts. Every file is a flake-parts module organized by feature (aspect), not by configuration class. Use when structuring Nix flakes, creating flake-parts modules, composing multi-host configs, organizing NixOS/home-manager/nix-darwin configuration, or sharing values across configuration classes. Triggers: nix flake structure, flake-parts modules, multi-host configs, aspect modules. Do NOT use for general Nix language questions, nixpkgs packaging, or NixOS module authoring unrelated to flake structure.
nix-shell
Search Nix packages and run commands with packages from nixpkgs that are not installed locally. Use when you need a package not available locally or want to search nixpkgs.
red-green-refactor
Domain-agnostic TDD methodology for iterative improvement. Enforces baseline measurement, minimal changes, and rigorous testing through commitment devices. Use when applying red-green-refactor workflow to any domain: prompts, skills, code, tests. Triggers: TDD methodology, baseline measurement, iterative improvement, red-green-refactor.
