Use `project-layout.md` to find it. If multiple descriptors exist, ask which one. Cache for the rest of the session.\n\nIf no descriptor exists yet, the user is starting from scratch. Two options:\n\n1. Create a minimal descriptor first (use `cayenne-modeling` to scaffold it), then open.\n2. Open the Modeler on *any* path it'll accept and use **File → New Project** inside.\n\nFor starting fresh, option 2 is simpler — but `open_project` does require an existing readable file.\n\n## Step 2 — Call `open_project`\n\n```\nmcp__cayenne__open_project({ \"projectPath\": \"\u003Cabsolute path to cayenne-*.xml>\" })\n```\n\nIf the tool is not available (MCP server not registered), surface `cayenne-mcp-server\u002FREADME.md` and stop. Do not attempt to launch CayenneModeler by any other means — the bundled launcher relies on the MCP server's discovery of the Modeler installation.\n\nThe tool spawns the Modeler asynchronously, then waits up to ~15 seconds for a startup handshake. Possible return codes:\n\n| Code | Meaning |\n|---|---|\n| `ok` | Modeler launched and loaded the project. |\n| `modeler_not_found` | The MCP jar is not co-located with a Modeler installation. User needs to install CayenneModeler properly. |\n| `project_not_found` | The `projectPath` doesn't exist or isn't readable. |\n| `handshake_timeout` | The Modeler started but didn't confirm load within the timeout. Often this means it's still loading — the user can check the GUI directly. |\n| `launch_failed` | Process spawn failed. Surface the error message. |\n\n## Step 3 — Hand off to the user\n\nOnce `open_project` returns `ok`, the user is in the GUI. From here, depending on intent:\n\n- **Reverse engineering**: that's the `cayenne-db-import` skill's job to walk them through. Do not duplicate that workflow here — just open and step out.\n- **Visual layout \u002F bulk editing**: tell the user what tab to navigate to (e.g., DataMap → ObjEntity for entity-level edits, DataMap → Class Generation for cgen config) and let them work. Don't try to script GUI actions.\n- **Just wanted to see the project**: nothing more to do.\n\n## When NOT to use this skill\n\n- **A-la-carte XML edits.** Adding one entity, tweaking one attribute, renaming a relationship — all faster as direct XML edits via `cayenne-modeling`. Don't context-switch the user to the GUI for trivial work.\n- **Class generation.** That's `cayenne-cgen`'s job, fully scripted via MCP. No GUI needed.\n\n## Anti-patterns\n\n- **Do not** trigger as a generic fallback for \"Cayenne tasks.\" This skill is for explicit user requests or inherently visual workflows. The `cayenne-modeling` skill handles most modeling intent.\n- **Do not** retry `open_project` on `handshake_timeout` — the Modeler may still be loading. Tell the user to check the GUI window directly.\n- **Do not** attempt to launch CayenneModeler outside the MCP tool (no `java -jar` direct calls, no opening a `.dmg`, no `open -a CayenneModeler`). The MCP tool's launcher knows where the installation lives.\n",{"data":41,"body":42},{"name":4,"description":6},{"type":43,"children":44},"root",[45,52,67,74,109,115,144,149,186,198,209,221,234,239,360,366,385,426,432,470,476],{"type":46,"tag":47,"props":48,"children":49},"element","h1",{"id":4},[50],{"type":51,"value":4},"text",{"type":46,"tag":53,"props":54,"children":55},"p",{},[56,58,65],{"type":51,"value":57},"Launch CayenneModeler with a Cayenne project file pre-loaded, via the ",{"type":46,"tag":59,"props":60,"children":62},"code",{"className":61},[],[63],{"type":51,"value":64},"mcp__cayenne__open_project",{"type":51,"value":66}," MCP tool.",{"type":46,"tag":68,"props":69,"children":71},"h2",{"id":70},"required-reading",[72],{"type":51,"value":73},"Required reading",{"type":46,"tag":75,"props":76,"children":77},"ul",{},[78,98],{"type":46,"tag":79,"props":80,"children":81},"li",{},[82,88,90,96],{"type":46,"tag":59,"props":83,"children":85},{"className":84},[],[86],{"type":51,"value":87},"${CLAUDE_PLUGIN_ROOT}\u002Freferences\u002Fmcp-tools.md",{"type":51,"value":89}," — ",{"type":46,"tag":59,"props":91,"children":93},{"className":92},[],[94],{"type":51,"value":95},"open_project",{"type":51,"value":97}," tool reference and failure modes.",{"type":46,"tag":79,"props":99,"children":100},{},[101,107],{"type":46,"tag":59,"props":102,"children":104},{"className":103},[],[105],{"type":51,"value":106},"${CLAUDE_PLUGIN_ROOT}\u002Freferences\u002Fproject-layout.md",{"type":51,"value":108}," — locate the project descriptor.",{"type":46,"tag":68,"props":110,"children":112},{"id":111},"step-1-resolve-the-project-path",[113],{"type":51,"value":114},"Step 1 — Resolve the project path",{"type":46,"tag":53,"props":116,"children":117},{},[118,120,126,128,134,136,142],{"type":51,"value":119},"The MCP tool needs an ",{"type":46,"tag":121,"props":122,"children":123},"strong",{},[124],{"type":51,"value":125},"absolute path",{"type":51,"value":127}," to a top-level project descriptor (",{"type":46,"tag":59,"props":129,"children":131},{"className":130},[],[132],{"type":51,"value":133},"cayenne-*.xml",{"type":51,"value":135},").
