Semantic memory search across all agent memories and conversation history. Use BEFORE answering questions about prior work, decisions, dates, people, preferences, projects, or past conversations. Also use when asked "do you remember", "what did we discuss", "when did we", etc.
Get current weather and forecasts. Use when the user asks about weather, temperature, or forecasts for any location.
Set up and use 1Password CLI (op). Use when installing the CLI, enabling desktop app integration, signing in (single or multi-account), or reading/injecting/running secrets via op.
Accessibility auditing: WCAG compliance checking, contrast ratios, ARIA labels, keyboard navigation, semantic HTML, screen reader compatibility.

Autonomous API testing and evaluation. Tests any REST API for correctness, security, performance, error handling, and standards compliance.

Use EVERY TIME you are about to spawn a sub-agent or do significant work. Classify the task first, then use the right model tier.
node ${MODEL_ROUTER_HOME:-$HOME/projects/model-router}/classify.cjs "your task description here"
Or get JSON for scripting:
node ${MODEL_ROUTER_HOME:-$HOME/projects/model-router}/classify.cjs --json "task description"
sessions_spawn(task=..., model="<model from classifier>")
node ${MODEL_ROUTER_HOME:-$HOME/projects/model-router}/log-usage.cjs --task "..." --tier fast --model "..."
Use for: summarize, format, extract, classify, convert, translate, clean data, rename, sort, filter Cost: ~1× baseline When in doubt about simple tasks, start here.
Use for: explain, compare, draft, review, outline, moderate analysis, code with clear spec Cost: ~15× baseline
Use for: deep analysis, architecture decisions, complex tradeoffs, research synthesis, debates, long-form strategy Cost: ~75× baseline Reserve for tasks where quality clearly matters more than speed/cost.
Fast triggers: summarize, format, extract, classify, categorize, convert, translate, list, count, clean, parse, fix typos, rename, sort, filter, deduplicate, "quick", "simple", "brief", "just"
Powerful triggers: "analyze deeply", architecture, tradeoffs, debate, hypothesis, synthesize, "design system", "evaluate options", comprehensive, thorough, research, strategy, critique, multiple complex questions
