Test an oh-my-opencode-slim release candidate or bugfix before publishing. Use when validating a packed plugin artifact, release branch, crash fix, OpenCode runtime compatibility, or model-specific smoke test such as OpenCode 1.17.11 message transform regressions.

Create EmDash CMS plugins with sandboxed hooks, routes, storage, content and media APIs, MCP tools, and declarative admin UI, or native React and Astro extensions. Use when scaffolding or implementing an EmDash plugin.

Psychologically grounded wisdom companion for inner life. Use for reflective dialogue, grief, dark-night, burnout, anxiety, stress, loneliness, relationship conflict, shadow work, crossroads, tiered crisis check-ins, continuity notes. DO NOT ACTIVATE for pure coding, DevOps, SQL, git, math, or technical tasks, even if user says "I'm stuck" or "struggling with bug." Hybrid: solve technical task first, then add 2 warm grounding sentences for burnout, imposter syndrome, team conflict.

Create custom desktop pet (Mate) characters with spritesheet and manifest. Use when the user asks to 'create a pet', 'make a desktop companion', 'design a mate character', 'generate a spritesheet for my pet', or wants to customize their desktop buddy. Generates a WebP spritesheet + manifest.json that can be loaded by MiMo Desktop's Mate system.

Schedule a prompt to fire on a fixed cadence (recurring loop). Use when the user asks to "run X every N minutes/hours/days", "loop X", "babysit Y", "be proactive about Y every N", or invokes `/loop` directly. Parses `[interval] <prompt>`, picks a clean cron expression, registers the job via the `cron` tool, and executes the prompt once immediately so the user sees activity without waiting for the first cron tick.

Translates Snowflake dbt SQL models to Standardized BigQuery SQL. Handles SQL compilation, Jinja macro placeholder masking, BigQuery Translation Service migration workflows, AST-based config transformations, explicit type casting, JSON extraction standardization, and deduplication. Use when migrating Snowflake dbt pipelines or models to BigQuery on Google Cloud. Don't use for generic BigQuery queries or non-Snowflake SQL migrations.

Troubleshoots Google Cloud Gemini Enterprise Agent Platform issues across Agent Gateway, Agent Connectivity Templates (ACT), Agent Registry, Agent Identity, Identity-Aware Proxy (IAP), Unified Access Policies (UAP), Model Armor, Semantic Governance Policies (SGP), Cloud DNS peering, Private CA TrustConfig, Next-Hop Secure Web Proxy (SWP), Explicit HTTPS Proxy (L4 AuthzPolicy), and Cloud Trace. Use when agent requests fail with 401/403/404/498/500/503 or Code 13, Egress request is not authorized, HTTP CONNECT fails with 404, Agent Runtime crashes on startup, or gateway/ACT/IAP/Model Armor/SGP configs fail validation. Don't use for general Google Cloud Identity and Access Management (IAM) debugging or networking issues unrelated to the Agent Platform stack.

Manage and query Agent Platform RAG Engine Corpora and retrieve grounded contexts using the Google GenAI SDK. Use when listing RAG corpora or files, inspecting a corpus, retrieving contexts, or generating content grounded in a RAG corpus. Do not use for standard database queries (use SQL/Spanner skills), Google Workspace RAG, or other RAG products like gRAG.

Agent Platform Model Registry Management. Use when you need to upload, list, describe, update, or delete machine learning models (and their versions) in the Agent Platform Model Registry. Don't use for model training, model deployment to endpoints, or managing non-Agent Platform models.

Deploy open models or custom weights from Model Garden to Agent Platform endpoints, check the status of an in-progress deployment operation, or clean up resources by undeploying models and deleting endpoints. Use when asked to actively deploy a model, list the Model Garden CATALOG of available models, check if a specific model is deployable (`gcloud ai model-garden models list-deployment-config`), query deployment cost, troubleshoot deployment errors (like quota limits), or undeploy/clean up endpoints. Also use when copying and deploying a 1P Tuned Model. Don't use for pure listing/discovery questions of the form "is X deployed?", "list my endpoints", or "which regions have models running?" — for those use `agent-platform-endpoint-management`. Don't use for running model evaluations (use `agent-platform-eval-flywheel` skill).

Check that every command the recording laws use, run at every place in Suggesting and in Editing on every small document with another author's pending change, records a document whose accept-everything result is what a plain editor gives, whose reject-everything result is the document before, whose undo and redo give back each side, and whose review ledger matches the kernel. Use before and after changing packages/plitejs/src/authored or packages/plitejs/src/history or another file in its coverage record, when the authored-recording step of pnpm check fails, or when fixing a recording bug a seed or a tester found.

Use when working with TradingView's lightweight-charts — creating charts, adding series (Line/Area/Bar/Candlestick/Histogram), configuring time and price scales, streaming realtime or historical data, panes, markers, per-bar/per-point colors, tooltips, coordinate conversion, custom plugins or primitives, non-financial horizontal scales, SSR/browser loading, or React/Vue/Web Components wrappers. Covers v5 API conventions and the common time, scale, marker, plugin, and wrapper foot-guns.

Flag concrete bugs introduced by a merged diff. Used only by the post-merge sweep (warden-sweep.yml); never gates clearance.

Extend a core journey in evals/core or write a one-off proof in evals/proofs that proves a PR's change to a human reviewer. Use when a PR changes user-visible behaviour, when a reviewer asks "show me", or when the coverage decision says a journey is missing.

Guide safe use of code_execution_remote for shell-backed execution on the connected A0 CLI host. Use when the user asks for their computer, local terminal, CLI host, remote shell, not Docker, or host-side Python/Node/terminal commands.

Drive a native GUI app (macOS, Windows, Linux) via the cua-driver CLI (default) or MCP server; snapshot its accessibility tree, act through snapshot-bound element tokens, native menu paths, exact window geometry, or pixel coordinates, and verify from fresh state. Use when the user asks you to operate, drive, automate, or perform a GUI task in a real application on the host, or to continue, resume, or recall recent Cua activity.

Commit, push, and open a PR. Use when asked to ship/open a PR, or for PR-description-only flows like writing, rewriting, or describing a PR body.

Create a focused workspace Skill from reusable decisions, knowledge, templates, or workflows in the current conversation. Use for /make-skill with a focus argument and requests such as save this workflow or turn this into a skill; do not use for one-off summaries or ordinary file creation.

Manage Chromium histograms and enums across code and XML metadata. Use when adding, extending, revising/renaming, or removing/obsoleting histograms or enums in C++, Java, histograms.xml, or enums.xml.
