Skills (12)

• autoresearch

  Run a metric-driven research loop: define a metric, evaluator, baseline, and target; evolve candidate solutions; score and adversarially verify them; then mutate survivors until the target, budget, or plateau ends the run. Use for measurable optimization of prompts, code, experiments, or creative va

• deep-research

  Conduct comprehensive multi-source research with AI-assisted analysis, adversarial claim verification, and explicit source synthesis. Use when investigating complex topics, comparing evidence, gathering current information, or producing a fact-finding report with citations and uncertainty notes. Do

• discover

  Answers every decision, explanation, and status question with an interactive board and discovers material unknowns before planning. Use for choosing between approaches, explaining anything, work status, blindspot passes, brainstorms, architecture and planning interviews, required pre-plan direction

• doctor

  Diagnose a structural issue observed while reading needed .state/ files, including overview.md, or fulfill an explicit state diagnostic request. Check one affected stream by default; use the state-wide scope for an observed overview issue or explicit global investigation. Propose only repairs needed

• handoff

  Create or execute a context-complete cross-domain plan as an orchestrator. Use when another agent must continue without prior context, or when a multi-domain plan needs coordinated execution while this skill retains decision ownership. For coding-session persistence, use essential:handover.

• handover

  Persist work stream state and update the global overview, both in the default source tree's centralized .state/, so the session can pause and any later session resume from the files on disk. Use when pausing coding work; this skill records continuity and does not execute the work.

• install-output-styles

  Install bundled Claude Code output-style Markdown files into ~/.claude/output-styles. Use when asked to install, refresh, or repair a response style shipped with this skill; do not use for editing style content or project-scoped .claude/output-styles files.

• install-statusline

  Install the bundled Bullet Train statusline into ~/.claude and wire settings.json statusLine. Use when setting up Claude Code on a new machine, installing or restoring the statusline, or repairing its configuration; preserve the bundled executable and report permission or platform limitations.

• install

  Install or refresh Essential's specialist agents for Claude Code, Codex, or Grok Build, and attach startup guidance in Grok's user configuration. Use when setting up this marketplace, installing its agent team, refreshing installed definitions, or restoring Grok's plugin instructions.

• sync

  Write the outcome of finished work back to the external systems it came from: move each linked Linear, Jira, Notion, or other tracker task to its new status with any deviations, and update linked design documents to match what shipped. Use after a PR merges, at session end, or when asked to sync, up

• takeover

  Resume paused work from the default source tree's centralized .state/works/. Offer incomplete streams, settle reviewing streams against applicable landing evidence, resolve pending decisions, select risk-appropriate implementation ownership, and drive one selected stream toward its charter. Promote

• uninstall

  Remove agents and startup configuration owned by Essential's installer while preserving edited and unrelated user files. Use when removing this marketplace's installed agent team, detaching its Grok startup guidance, or undoing an Essential installation in the active harness.
