Agent Skill: cloudharness

The cloudharness skill teaches AI coding agents how to autonomously navigate workspaces, execute tests, manage worktrees, and run tasks within Cloud Harness MCP.

Installation

# Skills CLI (recommended)
npx skills add bestagentkits/cloud-harness-mcp --skill cloudharness --global

# Claude Code Plugin
claude plugin install cloud-harness@bestagentkits

# OpenAI Codex Plugin
codex plugin add cloud-harness@bestagentkits

Capabilities Taught to the Agent

• Safe Lifecycle: Always keeping the workspaceId, closing stale shells before exit.
• Incremental Navigation: Using files_list pagination and grep_search rather than recursive host dumping.
• Atomic File Edits: Applying targeted patches with files_apply_patch instead of rewriting massive files.
• Clean Git Handoffs: Verifying commit status before calling git_push.
• Native Pull Request Reviews: Submitting COMMENT, APPROVE, or REQUEST_CHANGES reviews, inline file/line comments, thread replies and resolution, reviewer requests, draft/ready changes, and merges through github_action.

Example: Agent-Driven Pull Request Review

github_action covers the whole review lifecycle on the repository bound to a workspace. Mutations accept an idempotencyKey, so a retried call replays the first result instead of posting twice.

github_read   pr_view            { "prNumber": 42 }
github_read   pr_review_threads  { "prNumber": 42 }
github_action pr_review_comment  { "prNumber": 42, "path": "src/api.ts", "line": 18, "body": "Validate this input." }
github_action pr_review          { "prNumber": 42, "event": "REQUEST_CHANGES", "body": "See inline comments." }
  ... the author pushes fixes ...
github_read   pr_view            { "prNumber": 42 }
github_action pr_review_thread_resolve { "threadId": "PRRT_..." }
github_action pr_review          { "prNumber": 42, "event": "APPROVE" }
github_action pr_merge           { "prNumber": 42, "method": "squash", "matchHeadCommit": "<headRefOid from pr_view>" }

Approving or requesting changes on a pull request the acting identity authored is refused by GitHub (GITHUB_REVIEW_NOT_ALLOWED). Merge and auto-merge also need Contents: Read and write on the GitHub App; see GitHub App setup. Check workspace_capabilities (operations.pullRequestReview, pullRequestMerge, and githubActions) to see what the current credential can do.
