Set your API key (required — get one at https://jules.google.com/settings#api) export JULES_API_KEY="your-api-key-here" # 1. Verify available sources (pre-flight check) ./scripts/jules_api.sh sources # 2. Create a session with plan approval and auto PR creation ./scripts/jules_api.sh new-session \\ --source "sources/github/OWNER/REPO" \\ --title "Add unit tests" \\ --prompt "Add comprehensive unit tests for the authentication module" \\ --branch main \\ --require-plan-approval \\ --auto-pr # 3. Monitor session progress and approve the plan ./scripts/jules_api.sh activities --session SESSION_ID ./scripts/jules_api.sh approve-plan --session SESSION_ID Note: Use your GitHub username/org, not your local system username (e.g., sources/github/octocat/Hello-World, not sources/github/$USER/Hello-World). ### Overview This skill enables programmatic interaction with the Jules REST API (v1alpha) for delegating coding tasks to Jules, Google's autonomous AI coding agent. It supports: Task Assignment: Create new coding sessions with specific prompts Session Monitoring: Track session state and activities in real-time Plan Management: Approve or review generated plans Messaging: Send follow-up messages to active sessions Result Integration: Retrieve PR URLs and code changes from completed sessions ### 1. Get an API Key Create a Jules API key in the Jules web app: Navigate to: https://jules.google.com/settings#api You can have at most 3 API keys at a time Export it on the machine running the agent: export JULES_API_KEY="your-api-key-here" ### 2. Connect Your GitHub Repository Before the API can operate on a GitHub repo, you must: Install the Jules GitHub app via the Jules web UI Grant access to the specific repositories you want Jules to work on ### 3. Verify Repository Access # List available sources to verify access and see correct format ./scripts/jules_api.sh sources You'll see entries like: { "sources": [ { "name": "sources/github/octocat/Hello-World", "githubRepo": { "owner": "octocat", "repo": "Hello-World", "defaultBranch": { "displayName": "main" }, "branches": [ { "displayName": "main" }, { "displayName": "develop" } ] } } ] } ### Base URL & Authentication PropertyValueBase URLhttps://jules.googleapis.com/v1alphaAuth Headerx-goog-api-key: $JULES_API_KEY All requests authenticate with: -H "x-goog-api-key: $JULES_API_KEY" ### Resources ResourceDescriptionSourceA GitHub repository connected to Jules. Format: sources/github/{owner}/{repo}SessionA unit of work where Jules executes a coding task. Contains state, activities, and outputsActivityAn individual event within a session (plan generated, message sent, progress update, etc.) ### Session States StateDescriptionQUEUEDSession is waiting to startPLANNINGGenerating execution planAWAITING_PLAN_APPROVALWaiting for user to approve planAWAITING_USER_FEEDBACKNeeds user input to continueIN_PROGRESSActively executing the taskPAUSEDTemporarily stoppedCOMPLETEDSuccessfully finishedFAILEDEncountered an error ### Activity Types TypeDescriptionPlan GeneratedA plan was generated for the taskPlan ApprovedThe plan was approved (manually or auto)User MessageUser posted a message to the sessionAgent MessageJules posted a messageProgress UpdateStatus update on current workSession CompletedSession finished successfullySession FailedSession encountered an error ### Option 1: Session with Plan Approval and Auto-PR (Recommended) Create a session that requires plan approval before execution and automatically creates a PR when complete: ./scripts/jules_api.sh new-session \\ --source "sources/github/octocat/Hello-World" \\ --title "Fix login bug" \\ --prompt "Fix the null pointer exception in the login handler when email is empty" \\ --branch main \\ --require-plan-approval \\ --auto-pr Why this is recommended: You review and approve the plan before Jules executes changes PR is created automatically on completion Balances automation with human oversight ### Option 2: Fully Automated Session (No Plan Approval) For low-risk or routine tasks in non-sensitive repos, you can skip plan approval: # Create session without plan approval (use only for low-risk tasks) ./scripts/jules_api.sh new-session \\ --source "sources/github/octocat/Hello-World" \\ --title "Fix typo in README" \\ --prompt "Fix the typo in README.md line 5" \\ --branch main \\ --auto-pr Warning: Without --require-plan-approval, Jules will automatically approve its own plan and execute changes. Only use this for low-risk tasks in non-critical repos. ### Option 3: Interactive Session Send follow-up messages during an active session: # Create session ./scripts/jules_api.sh new-session \\ --source "sources/github/octocat/Hello-World" \\ --title "Add API endpoints" \\ --prompt "Add REST API endpoints for user management" \\ --branch main # Send additional instructions ./scripts/jules_api.sh send-message \\ --session SESSION_ID \\ --prompt "Also add input validation for all endpoints" ### Sources List Sources Lists all connected GitHub repositories. curl -sS \\ -H "x-goog-api-key: $JULES_API_KEY" \\ "https://jules.googleapis.com/v1alpha/sources" Query Parameters: ParameterTypeDefaultDescriptionpageSizeinteger30Number of sources to return (1-100)pageTokenstring-Token from previous response for paginationfilterstring-AIP-160 filter (e.g., name=sources/source1) Response: { "sources": [ { "name": "sources/github/octocat/Hello-World", "githubRepo": { "owner": "octocat", "repo": "Hello-World", "isPrivate": false, "defaultBranch": { "displayName": "main" }, "branches": [ { "displayName": "main" }, { "displayName": "develop" } ] } } ], "nextPageToken": "..." } Get Source Retrieves a single source by name. curl -sS \\ -H "x-goog-api-key: $JULES_API_KEY" \\ "https://jules.googleapis.com/v1alpha/sources/github/octocat/Hello-World" Use this to see available branches before creating a session. ### Sessions Create Session Creates a new coding session. curl -sS "https://jules.googleapis.com/v1alpha/sessions" \\ -X POST \\ -H "Content-Type: application/json" \\ -H "x-goog-api-key: $JULES_API_KEY" \\ -d '{ "prompt": "Add unit tests for the login module", "title": "Add Login Tests", "sourceContext": { "source": "sources/github/octocat/Hello-World", "githubRepoContext": { "startingBranch": "main" } }, "requirePlanApproval": true, "automationMode": "AUTO_CREATE_PR" }' Request Body Fields: FieldTypeRequiredDescriptionpromptstringYesThe task description for JulestitlestringNoShort title for the sessionsourceContext.sourcestringYesSource name (e.g., sources/github/owner/repo)sourceContext.githubRepoContext.startingBranchstringYesBranch to start fromrequirePlanApprovalbooleanNoIf true, pause for plan approval.

Usage: # List sources ./scripts/jules_api.sh sources # List sessions ./scripts/jules_api.sh sessions [--page-size N] # List activities for a session ./scripts/jules_api.sh activities --session [--page-size N] # Send message to session ./scripts/jules_api.sh send-message --session --prompt "..." # Approve plan ./scripts/jules_api.sh approve-plan --session # Create new session ./scripts/jules_api.sh new-session \\ --source "sources/github/owner/repo" \\ --title "..." \\ --prompt "..." \\ [--branch main] \\ [--auto-pr] \\ [--no-plan-approval] Flags: FlagDescription--sourceSource name (format: sources/github/owner/repo)--titleSession title--promptTask description or message content--sessionSession ID--branchStarting branch (default: main)--auto-prEnable automatic PR creation--require-plan-approvalRequire explicit plan approval (default)--no-plan-approvalSkip plan approval (use for low-risk tasks only)--page-sizeNumber of results to return ### jules.js The scripts/jules.js script wraps the Jules CLI for programmatic use. Usage: node scripts/jules.js version node scripts/jules.js list-repos node scripts/jules.js list-sessions node scripts/jules.js new --repo owner/repo --task "Your task" node scripts/jules.js pull --session SESSION_ID ### "Source not found" or "Repository not found" Cause: Repository not connected or incorrect source name format. Solution: Run ./scripts/jules_api.sh sources to list available sources Ensure you've installed the Jules GitHub app for this repo Use the exact source name from the list (e.g., sources/github/octocat/Hello-World) ### "Missing JULES_API_KEY" Cause: API key not set in environment. Solution: export JULES_API_KEY="your-api-key" ### Authentication Errors Cause: Invalid or expired API key. Solution: Generate a new API key at https://jules.google.com/settings#api Update the JULES_API_KEY environment variable Note: You can have at most 3 API keys at a time ### Session Stuck in AWAITING_PLAN_APPROVAL Cause: Session was created with requirePlanApproval: true. Solution: ./scripts/jules_api.sh approve-plan --session SESSION_ID ### Task Fails with Vague Error Cause: Vague prompts may produce unexpected results. Solution: Write clear, specific prompts Break large tasks into smaller, focused tasks Avoid prompts that require long-running commands (dev servers, watch scripts) ### Large Files Skipped Cause: Files exceeding 768,000 tokens may be skipped. Solution: Break down operations on very large files Consider splitting large files before processing ### Writing Effective Prompts Be specific: Instead of "fix the bug", say "fix the null pointer exception in auth.js:45 when email is undefined" Provide context: Mention relevant files, functions, or error messages Keep tasks focused: One logical task per session ### Monitoring Sessions Poll session state to track progress Check activities for detailed progress updates Handle AWAITING_USER_FEEDBACK state by sending clarifying messages ### Security Never include secrets or credentials in prompts Review generated PRs before merging Use requirePlanApproval: true (recommended for all repos, especially production) Only install the Jules GitHub app on repositories you intend to use with Jules — limit access scope Treat JULES_API_KEY as a secret: store it securely, rotate it regularly, and never paste it into untrusted places ### Performance Use automationMode: AUTO_CREATE_PR for streamlined workflows Only skip plan approval (requirePlanApproval: false) for routine, low-risk tasks in non-critical repos Break complex tasks into smaller sessions ### Extracting Results When a session completes, retrieve the PR URL from outputs: # Get session details curl -sS \\ -H "x-goog-api-key: $JULES_API_KEY" \\ "https://jules.googleapis.com/v1alpha/sessions/SESSION_ID" \\ | jq '.outputs[].pullRequest.url' ### Known Limitations Alpha API: Specifications may change; API keys and definitions are experimental No long-running commands: Jules cannot run npm run dev or similar watch scripts Context size: Files > 768,000 tokens may be skipped Prompt sensitivity: Vague prompts may produce unexpected results ### References Jules API Documentation Sessions Reference Activities Reference Sources Reference Types Reference Google Developers - Jules API Jules Settings (API Keys) ## Trust - Source: tencent - Verification: Indexed source record - Publisher: SanJacob99 - Version: 1.0.5 ## Source health - Status: healthy - Source download looks usable. - Yavira can redirect you to the upstream package for this source. - Health scope: source - Reason: direct_download_ok - Checked at: 2026-04-30T16:55:25.780Z - Expires at: 2026-05-07T16:55:25.780Z - Recommended action: Download for OpenClaw ## Links - [Detail page](https://openagent3.xyz/skills/jules-and-lobster) - [Send to Agent page](https://openagent3.xyz/skills/jules-and-lobster/agent) - [JSON manifest](https://openagent3.xyz/skills/jules-and-lobster/agent.json) - [Markdown brief](https://openagent3.xyz/skills/jules-and-lobster/agent.md) - [Download page](https://openagent3.xyz/downloads/jules-and-lobster)
