io.github.garrytan/gstack/open-gstack-browser

Launch GStack Browser — AI-controlled Chromium with the sidebar extension baked in.

io.github.garrytan/gstack/setup-gbrain

io.github.openai/codex/skill-installer

Install Codex skills into $CODEX_HOME/skills from a curated list or a GitHub repo path. Use when a user asks to list installable skills, install a curated skill, or install a skill from another repo (including private repos).

io.github.openai/codex/babysit-pr

Babysit a GitHub pull request after creation by continuously polling review comments, CI checks/workflow runs, and mergeability state until the PR is merged/closed or user help is required. Diagnose failures, retry likely flaky failures up to 3 times, auto-fix/push branch-related issues when appropriate, and keep watching open PRs so fresh review feedback is surfaced promptly. Use when the user asks Codex to monitor a PR, watch CI, handle review comments, or keep an eye on failures and feedback on an open PR.

io.github.openai/codex/imagegen

Generate or edit raster images when the task benefits from AI-created bitmap visuals such as photos, illustrations, textures, sprites, mockups, or transparent-background cutouts. Use when Codex should create a brand-new image, transform an existing image, or derive visual variants from references, and the output should be a bitmap asset rather than repo-native code or vector. Do not use when the task is better handled by editing existing SVG/vector/code-native assets, extending an established icon or logo system, or building the visual directly in HTML/CSS/canvas.

io.github.nrwl/nx/setup-review-sandbox

One-time setup of the sandbox prerequisites used by the reproduce-issue skill and the reproduce-verifier agent — Docker, the isolation runtime (gVisor on Linux / Colima on macOS), healthy container networking, and the nx-review-sandbox toolchain image (built from the repo's mise.toml). Idempotent; re-run any time to verify or repair. Use when the user says "set up the review sandbox", "install the sandbox prereqs", "build the sandbox image", or a reproduce-issue preflight reports something MISSING.

io.github.n8n-io/n8n/design-system

Guidelines on using Design System styles and components. Use when working on .vue files in packages/frontend. Triggers for tasks that include component architecture, styling, UI changes, or feature work.

io.github.supabase/supabase/ask-the-docs

Answer questions about the Supabase docs app (apps/docs) using documented architecture, build pipeline, and review-pattern notes, and apply feature-design principles (codebase reuse, coding minimalism) when proposing or critiquing changes. Use when the user asks "how does X work in the docs app?", "where does Y live?", "is this approach OK for the docs app?", or before writing non-trivial changes under apps/docs/ — especially anything touching the MDX pipeline, markdown generation, content components, federated docs, or contributor-facing authoring patterns. Can answer architecture questions with Mermaid diagrams when helpful.

io.github.n8n-io/n8n/public-api

Adds, migrates, or updates n8n Public API v1 endpoints with @PublicApiController — public DTOs, API-key and RBAC scopes, cursor pagination, OpenAPI + coverage wiring, and tests. Use when working under packages/cli/src/public-api/v1/ or when exposing an existing service through /api/v1.

io.github.discourse/discourse/discourse-writing-html-css

Write and repair HTML/CSS/SCSS for Discourse core, plugins, themes, and theme components. Use when authoring or modifying templates (.gjs/.hbs), stylesheets (.scss), component markup, class names, responsive layout, FormKit/select-kit styling, or CSS regressions. Covers Discourse's BEM-with-standalone-modifiers naming, the CSS custom-property color palette (theming + dark mode), template/HTML conventions, CSS repair patterns, and where stylesheets live.

io.github.koala73/worldmonitor/verify-worldmonitor

Launch and drive the WorldMonitor browser dashboard (Vite app at /dashboard) to prove user-facing behavior with screenshots and transcripts. Use when a change needs proof in the real app rather than only unit tests — panels, map layers, settings, search, country briefs, boot — or when asked to run, screenshot, or verify the dashboard.

io.github.Tracer-Cloud/opensre/tools

Read Yandex Cloud through its REST API. Applies to any question about VMs, metrics, logs, audit events, Kubernetes, managed databases, serverless, networking or any other Yandex Cloud resource. Never shell out to the `yc` CLI — it is not how this agent reaches Yandex Cloud and is usually not installed.

io.github.n8n-io/n8n/create-issue

Create Linear tickets or GitHub issues following n8n conventions. Use when the user asks to create a ticket, file a bug, open an issue, or says /create-issue.

io.github.skypilot-org/skypilot/skypilot

Use when launching cloud VMs, Kubernetes pods, or Slurm jobs for GPU/TPU/CPU workloads, training or fine-tuning models on cloud GPUs, deploying inference servers (vllm, TGI, etc.) with autoscaling, writing or debugging SkyPilot task YAML files, using spot/preemptible instances for cost savings, comparing GPU prices across clouds, managing compute across 25+ clouds, Kubernetes, Slurm, and on-prem clusters with failover between them, troubleshooting resource availability or SkyPilot errors, optimizing cost and GPU availability, or migrating an existing Slurm workload (converting sbatch scripts, salloc sessions, job arrays or srun invocations into SkyPilot task YAMLs, and mapping Slurm commands, directives and SLURM_* environment variables to their SkyPilot equivalents).

io.github.diegosouzapw/OmniRoute/omni-cli-tools

Manage CLI tool integrations exposed via the API. List, configure, and invoke CLI tool plugins that extend OmniRoute's automation surface.

io.github.diegosouzapw/OmniRoute/omni-db-backups

Trigger system backups, restore from backup files, and manage the SQLite database lifecycle. Supports export, import, and incremental snapshot strategies.

io.github.CopilotKit/CopilotKit/reskin

Author a NEW skin for the reskinnable-demo app. A skin is a self-contained domain plugin under src/skins/<id>/ that implements the frozen `Skin` contract (src/shell/skin-contract.ts) to swap the app's entire experience — brand, theme, layout, pages, tools, data, and agent — as a live sales demo. Use when the user says "add a skin", "create a skin", "new skin", "reskin the app", "make a <domain> skin", or wants the app re-themed as a new product. Do NOT use for editing the shell itself (src/shell/**), the shared token vocabulary (src/app/globals.css), or the shipped skins unless explicitly asked.
