Shrink and unify code without changing behavior. Use when: simplify, refactor, reduce duplication, remove lines, extract helper, reuse component, DRY, collapse, better abstraction.

Rank hot paths by CPU, memory, I/O, and contention; hand the optimization skill a scored target list. Use when: profile, flamegraph, hotspot, bottleneck, p95/p99, IOPS, fsync, "why is this slow".

Deploy and import Mattermost migration bundles. Use when validating handoff ZIPs, provisioning Mattermost, running mmctl import, configuring Nginx/WebSockets, or driving cutover.

Extract Slack workspaces into Mattermost import bundles. Use when exporting history, DMs, private channels, files, emoji, canvases, or building handoff ZIP/JSONL artifacts.

Keep a self-hosted Mattermost server healthy after the Phase 2 cutover. Use when running weekly health checks, applying OS security patches, upgrading Mattermost, taking and verifying PostgreSQL backups, scheduling reboots for off-hours windows, running quarterly restore drills, rotating credentials, responding to incidents, or executing disaster recovery against a lost host.

Generate a polished Nextra documentation site from any source repo. Use when building a docs site, "docs site for this repo", MDX docs, or deploying docs to Vercel.

Build production-grade support ticketing: schema, SLA engine, APIs, queues, admin/user UI, email, cron. Use when adding tickets or SLA tracking.

Triage support across any project (DB tickets, GitHub issues, Zendesk, Intercom). Use when reviewing tickets, SLA breaches, refunds, hostile users, GDPR/CCPA, or onboarding agent-driven support.

Search preprints from arXiv, bioRxiv, and medRxiv without API keys. Supports search, lookup, extraction, citations, enrichment, and paper downloads that bundle PDFs plus linked GitHub code.

Detect Codex and Claude sessions that were likely forgotten after a kernel panic, watchdog timeout, reboot, or crash. Use when the user wants to reconstruct interrupted work, group crash-time sessions by project, determine which sessions were resumed later, and identify likely-forgotten sessions from local transcript files and panic logs.

Coordinate NTM browser-testing swarms using agent-browser, next-browser, Playwright, React DevTools, Beads, and Agent Mail. Use when running parallel exploratory QA, visual/UX audits, Next.js runtime inspection, React profiling, browser evidence collection, or turning browser findings into beads.
