Remote control tmux sessions for interactive CLIs (python, gdb, git add -p, etc.) by sending keystrokes and scraping pane output. Use when debugging applications, running interactive REPLs (Python, gdb, ipdb, psql, mysql, node), automating terminal workflows, interactive git commands (git add -p, git stash -p, git rebase -i), or when user mentions tmux, debugging, or interactive shells.

duckdb

DuckDB — the in-process, columnar, vectorized OLAP SQL engine shipped as a single zero-dependency binary ("SQLite for analytics"). Use when querying Parquet/CSV/JSON files directly with SQL and no load step, doing in-process analytical/OLAP queries and aggregations, using the `duckdb` CLI shell (interactive REPL or `-c`/`-json` one-shots for scripts and agents), writing "friendly SQL" (FROM-first, `SELECT * EXCLUDE`, `GROUP BY ALL`, `SUMMARIZE`, `PIVOT`), converting CSV↔Parquet↔JSON with `COPY`, reading remote data over HTTP/S3 via the httpfs extension, or `ATTACH`-ing a live Postgres/MySQL/SQLite database. Triggers on mentions of duckdb, the `duckdb` command, `.duckdb` files, replacement scans, `read_parquet`/`read_csv`, httpfs/`CREATE SECRET`, or "embedded analytics database". This is the DuckDB CLI and SQL dialect, NOT a generic SQL tutorial and NOT the DuckDB client libraries (Python/Node/Java — defer those to duckdb.org).

k3s

The k3s lightweight CNCF-certified Kubernetes distribution shipped as a single binary that bundles containerd, flannel, CoreDNS, Traefik, ServiceLB (Klipper), local-path-provisioner, and metrics-server. Use when installing or running a lightweight Kubernetes cluster, bootstrapping a single-node or HA k3s control plane, joining agent (worker) nodes, choosing embedded etcd vs an external SQL datastore, managing cluster/agent tokens, rotating certificates, taking or restoring etcd snapshots, enabling secrets encryption, doing airgap or private-registry installs, disabling bundled components (Traefik/ServiceLB/CoreDNS), or upgrading k3s. Triggers on mentions of k3s, `k3s server`, `k3s agent`, the `curl -sfL https://get.k3s.io | sh -` installer, `/etc/rancher/k3s/`, or Rancher's lightweight Kubernetes. This is the k3s CLI/distribution, NOT generic Kubernetes/kubectl.

fzf

Command-line fuzzy finder for interactive filtering of any list. Use when interactively selecting files, searching command history (CTRL-R), creating selection interfaces in scripts, building interactive menus, or integrating fuzzy search with tools like ripgrep, fd, and git. Triggers on mentions of fzf, fuzzy finder, ** completion, interactive filtering, or shell keybindings CTRL-T/CTRL-R/ALT-C.

jq

jq — the command-line JSON processor and its filter language for slicing, filtering, transforming, and reshaping JSON. Use when extracting fields or nested paths from JSON on the command line, filtering/`select`-ing arrays of objects, reshaping or building new JSON objects, emitting CSV/TSV with `@csv`/`@tsv`, getting raw unquoted strings for shell capture with `jq -r`, slurping (`-s`) and aggregating JSON (`add`, `group_by`, averages), parsing API responses, NDJSON pipelines (`-c`), or injecting shell values safely with `--arg`/`--argjson`/`$ENV`. Triggers on mentions of jq, the `jq` command, the jq filter language, `jq -r`, `.foo`/`.[]` filters, `@csv`/`@tsv`, slurp/`fromjson`, or "filter/transform JSON in the terminal". This is the jq CLI and filter language, NOT a generic JSON tutorial and NOT jq language bindings (jaq, gojq, PyPI `jq` — defer those to their own docs).

long-form-math

Write mathematics in a long-form, understanding-focused style with detailed proofs and rich exposition. Use when explaining mathematical concepts, writing proofs, tutoring math, creating educational math content, or when the user asks for mathematical explanations. Inspired by Jay Cummings' Real Analysis and Chartrand's Mathematical Proofs. Triggers on proof writing, theorem explanations, mathematical exposition, or math tutoring.

fd

A fast, user-friendly command-line tool for finding files and directories by name — a simpler, faster `find` replacement. Use when searching for files or directories by name or regex/glob pattern, filtering results by type, extension, size, or modified time, respecting .gitignore, or running a command per result with -x/-X. Triggers on mentions of the fd command, fdfind, "find files named", "search for a file", or replacing `find`. This is the fd CLI tool, NOT the file-search MCP server.

hledger

Plain-text double-entry accounting with hledger. Use when recording transactions, checking balances, generating financial reports (balance sheet, income statement, cashflow), importing CSV bank statements, budgeting, tracking time, managing multiple currencies, or doing year-end closing. Triggers on mentions of hledger, ledger-cli, journal files, double-entry accounting, balance assertions, or plain-text accounting.

walkthrough-to-obsidian

Convert game walkthroughs and guides from plain text into structured, interlinked Obsidian markdown pages. Use when the user wants to convert a walkthrough, FAQ, guide, or reference document into Obsidian vault pages. Triggers on mentions of converting walkthroughs, guides, or FAQs to Obsidian, or splitting a large text file into Obsidian pages.

chrome-cdp

Interact with local Chrome browser session via Chrome DevTools Protocol. Use when asked to inspect, debug, or interact with a page open in Chrome, take screenshots of browser tabs, read accessibility trees, evaluate JavaScript, click elements, navigate pages, or automate browser interactions in a live Chrome session.

ansible

ansible-core — the agentless, push-based, SSH automation engine that runs idempotent tasks from declarative YAML playbooks. Use when writing or running Ansible playbooks, issuing ad-hoc commands (`ansible -m`), managing INI/YAML inventory, authoring roles, installing collections with `ansible-galaxy`, encrypting secrets with Ansible Vault, tuning `ansible.cfg`, looking up module docs with `ansible-doc`, or provisioning/configuring hosts idempotently over SSH. Covers the ten `ansible*` CLIs, FQCN (`ansible.builtin.*`), become/privilege escalation, inventory patterns, variable precedence, check/diff mode, and strategies. Triggers on mentions of ansible, ansible-playbook, ansible-galaxy, ansible-vault, ansible-inventory, ansible.cfg, playbooks, roles, collections, or Ansible Vault. This is ansible-core (the engine + `ansible.builtin`), NOT generic configuration-management theory and NOT the bundled community `ansible` package's collection modules.
