How to create new skills for an agent-native app. Use when adding a new skill, documenting a pattern the agent should follow, or creating reusable guidance for the agent.

How to delegate all AI work to the agent chat. Use when delegating AI work from UI or scripts to the agent, when a user asks for agent behavior or LLM-powered features, when tempted to add inline LLM calls, or when sending messages to the agent from application code.

How to write great agent instructions for an agent-native app or template: AGENTS.md, skills, and tool/action descriptions. Use when authoring or reviewing AGENTS.md, writing a SKILL.md, wording action descriptions, or deciding what belongs in instructions vs skills vs memory.

How to conduct ad-hoc analyses: gather data from multiple sources, synthesize findings, save reusable analysis artifacts that anyone can re-run for fresh results.

Use when an analytics question spans multiple data sources (e.g. warehouse events + CRM + support + first-party) and you must stitch identities, remove duplicates, and produce one consolidated answer with per-source provenance.

How analytics dashboards are stored, created, and modified. Covers SQL dashboard tables, legacy settings migration, valid panel sources, layout shape, and safe update patterns.

General guidance on querying data sources, using existing scripts vs ad-hoc queries, filtering patterns, and generating charts for the analytics app.

Work with the Brain institutional-memory template, including importing captures, validating quote evidence, writing knowledge, and reviewing proposals.

Unzip or extract a zip file in the project. Use when the user says "unzip", "extract zip", "unzip file", or asks to extract a .zip archive. Finds the most recently modified .zip file in the codebase and extracts it to the project root using `npx extract-zip`.

Automate browser interactions, test web pages and work with Playwright tests.

Anti-AI-slop design skill for greenfield pages, audits, redesigns, and design extraction from URLs or screenshots. Use when the user asks to build a new app or landing page, wants to redesign something, invokes Hallmark by name, or uses audit/redesign/study.

Install Maestro, run end-to-end tests, and create new test flows for the iOS and Android apps in this project. Use when the user asks to test the mobile apps, verify a feature on iOS or Android, set up Maestro, run a smoke test, write a new flow, or wants automated UI feedback after implementing mobile functionality, even if they don't say "Maestro".

Creates AGENTS.md with concise instructions if needed.

Build and run the Android app on an emulator or physical device. Use when the user asks to build, compile, run, launch, or deploy the Android app, or mentions the APK, Gradle, emulator, device, or native-run, even if they don't explicitly say "android-native".

Build and run the iOS app on a simulator or device. Use when the user asks to build, compile, run, launch, or deploy the iOS app, or mentions Xcode, xcodebuild, xcrun, the IPA, simulator, or native-run, even if they don't explicitly say "ios-native".

Imports a Builder.io prototype into the current project by running the Builder dev-tools CLI. Use when the user mentions importing a prototype, a Builder.io URL, a builder.io/app/projects link, or wants to bring in designs or components from a Builder prototype. Triggers on phrases like "import prototype", "use this builder url", "import from builder", or when a builder.io/app/projects URL is shared.

Search, read, create, and update Jira issues, check sprint status, and see who's working on what. Use this skill whenever the user mentions Jira, asks about tickets, issues, sprints, or story points, references issue keys like PROJ-123, wants to know what someone is working on, asks about the current sprint, or says things like "check Jira", "what's the status of X", "find tickets about Y", "who's assigned to Z", "what's in the sprint", or "show me my open issues". Also use this skill when the user asks to create, file, open, or log a Jira ticket, or to move, transition, update, or change the status of an existing issue. Trigger phrases include "create a Jira ticket", "file a bug", "open an issue", "log a task in Jira", "mark PROJ-123 as done", "move the ticket to In Progress", "close ENG-456", or "transition the issue to Review".

Interact with Slack workspaces — search messages, read channel history, browse threads, list channels, and find users. Use this skill whenever the user mentions Slack, asks about messages in a channel, wants to check what people said about a topic, look up Slack users, or references #channel-names. Also trigger when the user says things like "check Slack", "what's happening in #X", "find messages about Y", "who said Z", or any task involving reading from Slack. Even if the user doesn't say "Slack" explicitly but mentions a #channel, use this skill.

Helps users discover and install agent skills when they ask questions like "how do I do X", "find a skill for X", "is there a skill that can...", or express interest in extending capabilities. This skill should be used when the user is looking for functionality that might exist as an installable skill.

Expert help with GitHub CLI (gh) for managing pull requests, issues, repositories, workflows, and releases. Use this when working with GitHub operations from the command line.

Create new skills, modify and improve existing skills, and measure skill performance. Use when users want to create a skill from scratch, update or optimize an existing skill, run evals to test a skill, benchmark skill performance with variance analysis, or optimize a skill's description for better triggering accuracy.
