Handles fetching the skill files and placing them in .agents/skills/. This does not author new skills — to create a new skill from scratch (no source URL), use the skill-creator skill instead.

Bitbucket integration hub. Detects whether the repository is on Bitbucket Cloud or Bitbucket Data Center and directs you to the matching detailed skill (bitbucket-cloud or bitbucket-data-center). Use for any Bitbucket repository or pull request task.

Set up and manage local Kubernetes clusters using KIND (Kubernetes IN Docker). Use when testing Kubernetes applications locally or developing cloud-native workloads.

This skill should be used when the user asks to "QA a pull request", "test PR changes", "verify a PR works", "functionally test changes", or when an automated workflow triggers QA validation of code changes. Provides a structured methodology for setting up the environment, exercising changed behavior, and reporting results.

Create an automation that reads a list of public RSS and Atom feeds on a schedule - daily by default - keeps what is new and matches the configured topics, and has an agent write a short digest of it. It needs no credentials: the feeds are public URLs and the conversation is started with no secrets and no MCP servers.

This skill should be used when the user wants to "add a skill", "create a skill", "make a new skill", "write a new skill", "improve skill description", "organize skill content", or needs guidance on skill structure, progressive disclosure, or skill development best practices. Use this (not add-skill) when authoring a new skill from scratch rather than importing one from a GitHub URL.

Create, debug, and test GitHub Actions workflows and custom actions. Use when building CI/CD pipelines, automating workflows, or troubleshooting GitHub Actions.

Create an automation that writes a recurring research brief. Uses Tavily MCP for web research and Notion MCP to publish the final brief with executive summary, implications, and source citations.

Bitbucket Cloud (bitbucket.org) specifics — authenticate with BITBUCKET_TOKEN, use the REST API v2, workspace/repo_slug repositories, and the create_bitbucket_pr tool. Loaded on demand by the bitbucket skill once a Cloud environment is detected.

Simplifies and refines code for clarity, consistency, and maintainability while preserving all functionality. Analyzes recently modified code across three dimensions - code reuse, code quality, and efficiency - and provides actionable improvement suggestions. This skill should be used when the user asks to "simplify code", "refine code", "clean up code", "improve code quality", or requests a simplification review of recent changes.

Post PR review comments using the GitHub API with inline comments, suggestions, and priority labels.

This skill should be used when the user asks to "set up a Jira automation to create pull requests", "poll Jira for create-pr issues", "automatically create GitHub PRs from Jira tickets", "deploy a Jira issue-to-PR automation", "create a Jira to GitHub PR workflow", or mentions automating GitHub PR creation from a Jira label. Deploys a cron-based OpenHands automation that watches a Jira Cloud project for issues labeled with a configurable label (default: "create-pr") and spawns an agent conversation to create a GitHub pull request for each new issue found. The target GitHub repository is read from the body of the Jira ticket - no repo parameter is required at deploy time.

Guides technical explanations toward flowing, direct, conversational prose. This skill should be used for engineering chat, design discussion, architecture analysis, code-review explanations, and technical recommendations that should be concise without becoming fragmented or vague.

Create an automation that implements GitHub issues when a configurable trigger label is applied. Polls one or more repositories deterministically, clones the default branch, starts one OpenHands conversation per label event, then commits, pushes, and opens the pull request itself.

Create an automation that reviews GitHub pull requests when a configurable trigger label is applied. Polls one or more repositories deterministically, starts one OpenHands review conversation per label event with the pull request's head commit already checked out, and publishes the review to GitHub.

This skill should be used when the user asks to "keep a fork in sync", "rebase local changes on upstream", "sync my fork nightly", "long-lived fork", or "automate upstream rebases". Guides the user through creating a cron automation that fetches upstream changes, rebases local customizations on top, verifies the software works, and replaces the running version when the rebase is clean.

This skill should be used when the user asks to "monitor a GitHub repository", "watch GitHub for issues or PRs", "respond to @OpenHands mentions on GitHub", "set up an OpenHands GitHub integration", "trigger OpenHands from a GitHub comment", or "poll a GitHub repo for a trigger phrase". Guides the user through creating a cron automation that polls a single repository and starts an OpenHands conversation whenever a configurable trigger phrase is detected in an issue or PR comment.

This skill should be used when the user asks to "create an automation", "schedule a task", "set up a cron job", "webhook integration", "event-triggered automation", or mentions automations, scheduled tasks, cron scheduling, or webhook events in OpenHands Cloud.

Create an automation that generates an async standup digest from Slack. Searches selected channels for messages since the previous workday, groups updates by project, highlights blockers and decisions, and posts a summary to a target channel.

Bitbucket Data Center (self-hosted Bitbucket Server) specifics — authenticate with BITBUCKET_DATA_CENTER_TOKEN, use the REST API 1.0, PROJECT/repo_slug repositories, scm/ git remotes, and the create_bitbucket_data_center_pr tool. Loaded on demand by the bitbucket skill once a Data Center environment is detected.

This skill should be used when the user asks to "write in plain English", "make this easier to read", "rewrite guidance", "improve report clarity", or produce accessible public-facing prose. It applies plain English content design principles: active voice, front-loaded content, sentence case, and no bold or italics for emphasis.

This skill should be used when the user asks to "monitor a Slack channel", "watch Slack for messages", "create a Slack bot that responds to mentions", "set up an OpenHands Slack integration", "trigger OpenHands from Slack", "respond to @openhands in Slack", or "poll Slack channels for a trigger phrase". Guides the user through creating a cron automation that watches up to 10 Slack channels and starts an OpenHands conversation whenever a configurable trigger phrase is detected.

Upgrade Apache Spark applications between major versions (2.x→3.x, 3.x→4.x). Covers build files, deprecated APIs, configuration changes, SQL/DataFrame updates, and test validation.

Set up a ticket-to-code-change automation using Jira or Linear as the issue tracker and GitHub, GitLab, or Bitbucket as the source-control provider. Watches for implementation-ready tickets, starts an OpenHands conversation to implement and test the request, opens a pull or merge request, and links the result back to the ticket.

Create an automation that drafts incident retrospectives. Gathers incident-channel messages from Slack, collects linked tickets and follow-ups from Linear, and publishes a retrospective draft to Notion with a timeline, impact summary, root-cause hypotheses, and action items.

Distill code review feedback from GitHub PRs into reusable skills and guidelines. This skill should be used when users ask to "learn from code reviews", "distill PR feedback", "improve coding standards", "extract learnings from reviews", or want to generate skills/guidelines from historical review comments.

Work effectively inside a local Agent Canvas environment, including local agent-server auth, frontend/backend port discovery, safe workspace hygiene, and delegating work to a new local conversation through POST /api/conversations.

Back factual claims and field values with official, verifiable sources. Use when the user asks to fill fields, answer questions, or make claims that must be supported by an exact quote and an official link.

Create an automation that keeps AGENTS.md current in one or more GitHub repositories. On a schedule - weekly by default - it clones the default branch, starts an OpenHands conversation that reads the repository and creates or updates AGENTS.md, and opens a pull request with the result.
