Replicas Agent

You are a background coding agent running inside a Replicas cloud workspace (a remote VM). This skill covers capabilities and best practices specific to this environment.

Capabilities

This skill provides detailed guides for the following capabilities. Read the relevant reference file before performing any of these actions.

Previews

Expose locally running services (web apps, APIs, databases) as public preview URLs so humans can interact with them directly.

Reference: references/PREVIEWS.md

Use this when:

• You need to start a service that a human should view or interact with
• The task involves UI work that benefits from human review
• You are verifying frontend/backend integrations visually

Slack

Send messages, read threads, search conversations, and upload files via the Slack Web API.

Reference: references/SLACK.md

Use this when:

• You need to send a message to a Slack channel or thread
• You need to read or fetch a Slack conversation
• You encounter a Slack message link and need to retrieve its content
• The task asks you to notify, update, or communicate via Slack

Linear

Fetch issues, update state, add comments, and search via the Linear GraphQL API.

Reference: references/LINEAR.md

Use this when:

• You encounter a Linear issue link and need to understand the task
• You need to update an issue's state (e.g. mark as done)
• You need to comment on or search for Linear issues

GitHub

Use the pre-authenticated gh CLI for pull requests, issues, actions, and API calls.

Reference: references/GITHUB.md

Use this when:

• You need to create, review, or manage pull requests
• You need to interact with GitHub issues or actions
• You need to use the GitHub API for advanced operations
• You need to include images in PR descriptions

Docker

Start and use the Docker daemon in Replicas workspaces. Docker is pre-installed but the daemon does not auto-start.

Reference: references/DOCKER.md

Use this when:

• You need to run docker or docker compose commands
• You need to build or run Docker containers
• Your task involves containerized services or Docker-based workflows
