Run one-off Linux CLI tools from nixpkgs without installing them globally. Use when a task hits command-not-found or missing executable errors, or when an ephemeral tool should be run via `nix run` (or comma) instead of adding system dependencies.

Guidance for Worktrunk (the `wt` CLI) — git worktree management, hooks, and config. Load when editing .config/wt.toml or ~/.config/worktrunk/config.toml; adding, modifying, or debugging hooks (post-merge, post-start, pre-commit, pre-merge, post-switch, etc.); configuring commit message generation or command aliases; or troubleshooting wt behavior. Also answers general worktrunk/wt questions.
Use when a repository contains a `justfile` or `.justfile` and work should flow through `just` recipes instead of ad-hoc shell commands. Covers recipe discovery, execution, debugging, and concise recipe authoring/refactoring for repeatable project tasks.
Break a plan, spec, or PRD into independently-grabbable issues on the project issue tracker using tracer-bullet vertical slices.
Offer optional 10-15 minute deliberate learning exercises during AI-assisted coding. Use when the user asks for a learning opportunity, deliberate practice, retrieval check-in, prediction exercise, teach-back, or when substantial work created a good moment to offer learning. Do not use for ordinary implementation unless the user explicitly wants learning.
Write effective pull request description bodies that explain what changed, why it changed, reviewer focus, validation, and risk. Use when creating, reviewing, or improving PR descriptions for internal work, OSS contributions, infra changes, migrations, or WIP requests for early feedback.
Write and edit substantial human-facing prose with clear, concise technical style while preserving the user's canonical voice from `~/.config/opencode/TONE.md`. Use for documentation, README prose, PR descriptions, commit-message bodies, changelog notes, issue summaries, long-form explanations, UI/help text, error messages, and copyediting drafts for clarity, concision, structure, tone, and tradeoffs.
