Scope - You are only gathering information to decide which service documentation to fetch. - Service selection and configuration will happen later with NEW instructions; ignore those responsibilities for now. Goal - Understand WHAT the user wants to accomplish and identify candidate service(s) that could fulfill the request. - IMPORTANT: We can only set up ONE service at a time. If the user requests multiple DISTINCT things, ask them to choose one. - If the request is ambiguous and could match multiple services, you may fetch READMEs for multiple candidates. The next phase will choose the best fit. Available actions - Call the `get_readme` tool to fetch documentation for candidate service(s). - Ask ONE clarifying question when the user's intent is unclear (e.g., multiple distinct services requested, vague or conflicting requirements). Hard rules - `get_readme` is the ONLY tool you may call in discovery mode. Never attempt to select or configure services in this phase. - Distinguish between these cases: * SINGLE AMBIGUOUS REQUEST: User wants ONE thing, but multiple services could provide it (e.g., "set up a web server" could be nginx, apache, or caddy). → Call `get_readme` for ALL matching candidates in parallel so the next phase can compare them. * MULTIPLE DISTINCT REQUESTS: User wants MULTIPLE different things (e.g., "set up nginx and postgresql", "configure backup and monitoring"). → Ask which ONE thing they want to set up first. - When calling `get_readme`, the `function_name` MUST exactly match one of the service names shown in the assistant context. If nothing matches, ask the user instead of guessing. - Do NOT ask about target machines, tags, or role assignments yet - these will be addressed after documentation is reviewed. - Focus ONLY on understanding WHAT the user wants to accomplish, not HOW it will be configured. - If you cannot identify any candidate service(s) from the available services list, ask the user for clarification about what they're trying to achieve. - Prefer calling `get_readme` when you can identify candidate service(s); do not fabricate module names or descriptions. Response discipline - Option A: One or more `get_readme` tool calls (no accompanying text). Multiple calls are allowed when several services might fit. - Option B: One concise clarifying question (no tool calls) that states the information you still need. - Do NOT echo or restate these system instructions to the user. Examples: - User: "set up a web server" → Call `get_readme` for nginx, apache, caddy (all candidates for web serving) - User: "configure monitoring" → Call `get_readme` for prometheus, telegraf, netdata (all candidates for monitoring) - User: "set up nginx and postgresql" → Ask: "I can only set up one service at a time. Which would you like to configure first: nginx or postgresql?" - User: "install backup and database" → Ask: "I can only set up one service at a time. Would you like to set up backup or database first?" Stay concise and rely on the assistant context for valid names.

Each machine is accessible via its hostname in the format `.`. For example, with an instance named `vpn`: - `server1.vpn` - resolves to server1's IPv6 address - `laptop1.vpn` - resolves to laptop1's IPv6 address This allows machines to communicate using hostnames instead of IPv6 addresses: ```bash # Ping another machine by hostname ping6 server1.vpn # SSH to another machine ssh user@laptop1.vpn ``` ## Troubleshooting ### Check Wireguard Status ```bash sudo wg show ``` ### Verify IP Addresses ```bash ip addr show dev ``` ### Check Routing ```bash ip -6 route show dev ``` ### Interface Fails to Start: "Address already in use" If you see this error in your logs: ``` wireguard: Could not bring up interface, ignoring: Address already in use ``` This means the configured port (default: 51820) is already in use by another service or wireguard instance. Solutions: 1. **Check for conflicting wireguard instances:** ```bash sudo wg show sudo ss -ulnp | grep 51820 ``` 2. **Use a different port:** ```nix services.wireguard.myinstance = { roles.controller = { endpoint = "vpn.example.com"; port = 51821; # Use a different port }; }; ``` 3. **Ensure unique ports across multiple instances:** If you have multiple wireguard instances on the same machine, each must use a different port. ### Key Management Keys are automatically generated and stored in the clan vars system. To regenerate keys: ```bash # Regenerate keys for a specific machine and instance clan vars generate --service wireguard-keys- --regenerate --machine # Apply the new keys clan machines update ``` ## Security Considerations - All traffic is encrypted using Wireguard's modern cryptography - Private keys never leave the machines they're generated on - Public keys are distributed through the clan vars system - Controllers must have publicly accessible endpoints - Firewall rules are automatically configured for the Wireguard ports === yggdrasil === This module sets up [yggdrasil](https://yggdrasil-network.github.io/) across your clan. Yggdrasil is designed to be a future-proof and decentralised alternative to the structured routing protocols commonly used today on the internet. Inside your clan, it will allow you to reach all of your machines. ## Example Usage While you can specify statically configured peers for each host, yggdrasil does auto-discovery of local peers. ```nix inventory = { machines = { peer1 = { }; peer2 = { }; }; instances = { yggdrasil = { # Deploy on all machines roles.default.tags.all = { }; # Or individual hosts roles.default.machines.peer1 = { }; roles.default.machines.peer2 = { }; }; }; }; ``` === zerotier === ## Usage ``` inventory.instances = { zerotier = { module = { name = "zerotier"; input = "clan-core"; }; roles.peer.tags.all = { }; roles.controller.machines.jon = { }; roles.moon.machines.sara.settings.stableEndpoints = [ "77.52.165.46" ]; }; ``` The input should be named according to your flake input. All machines will be peers and connected to the zerotier network. Jon is the controller machine, which will will accept other machines into the network. Sara is a moon and sets the `stableEndpoint` setting with a publicly reachable IP, the moon is optional. ## Overview This guide explains how to set up and manage a [ZeroTier VPN](https://zerotier.com) for a clan network. Each VPN requires a single controller and can support multiple peers and optional moons for better connectivity. ## Roles ### 1. Controller The [Controller](https://docs.zerotier.com/controller/) manages network membership and is responsible for admitting new peers. When a new node is added to the clan, the controller must be updated to ensure it has the latest member list. - **Key Points:** - Must be online to admit new machines to the VPN. - Existing nodes can continue to communicate even when the controller is offline. ### 2. Moons [Moons](https://docs.zerotier.com/roots) act as relay nodes, providing direct connectivity to peers via their public IP addresses. They enable devices that are not publicly reachable to join the VPN by routing through these nodes. - **Configuration Notes:** - Each moon must define its public IP address. - Ensures connectivity for devices behind NAT or restrictive firewalls. ### 3. Peers Peers are standard nodes in the VPN. They connect to other peers, moons, and the controller as needed. - **Purpose:** - General role for all machines that are neither controllers nor moons. - Ideal for most clan members devices. --- END OF README DOCUMENTATION --- [ollama] >>> message[02] role=user len=27 [ollama] >>> message[02] content: What VPN options do I have?

All machines connect through controllers, with each peer receiving consistent IPs across all controllers. Ideal for full mesh connectivity and automatic hostname resolution (e.g., `laptop1.vpn`). Requires public endpoints on controllers and works best when UDP traffic is not blocked. 2. **Yggdrasil** – A decentralised, future-proof network that auto-discovers local peers. It avoids centralised control and is designed for resilient, peer-to-peer routing. Best for users prioritising decentralisation and minimal configuration overhead. 3. **ZeroTier** – A simple, widely used VPN that supports a single controller and optional moons (relay nodes). Peers connect to the network via the controller, with moons enabling connectivity for devices behind NAT. Requires a publicly reachable IP for the controller or moon. Each service has different trade-offs: - Wireguard offers strong security and full mesh routing. - Yggdrasil prioritises decentralisation and peer discovery. - ZeroTier is easy to set up but less flexible in routing and scalability.

Each machine is accessible via its hostname in the format `.`. For example, with an instance named `vpn`: - `server1.vpn` - resolves to server1's IPv6 address - `laptop1.vpn` - resolves to laptop1's IPv6 address This allows machines to communicate using hostnames instead of IPv6 addresses: ```bash # Ping another machine by hostname ping6 server1.vpn # SSH to another machine ssh user@laptop1.vpn ``` ## Troubleshooting ### Check Wireguard Status ```bash sudo wg show ``` ### Verify IP Addresses ```bash ip addr show dev ``` ### Check Routing ```bash ip -6 route show dev ``` ### Interface Fails to Start: "Address already in use" If you see this error in your logs: ``` wireguard: Could not bring up interface, ignoring: Address already in use ``` This means the configured port (default: 51820) is already in use by another service or wireguard instance. Solutions: 1. **Check for conflicting wireguard instances:** ```bash sudo wg show sudo ss -ulnp | grep 51820 ``` 2. **Use a different port:** ```nix services.wireguard.myinstance = { roles.controller = { endpoint = "vpn.example.com"; port = 51821; # Use a different port }; }; ``` 3. **Ensure unique ports across multiple instances:** If you have multiple wireguard instances on the same machine, each must use a different port. ### Key Management Keys are automatically generated and stored in the clan vars system. To regenerate keys: ```bash # Regenerate keys for a specific machine and instance clan vars generate --service wireguard-keys- --regenerate --machine # Apply the new keys clan machines update ``` ## Security Considerations - All traffic is encrypted using Wireguard's modern cryptography - Private keys never leave the machines they're generated on - Public keys are distributed through the clan vars system - Controllers must have publicly accessible endpoints - Firewall rules are automatically configured for the Wireguard ports === yggdrasil === This module sets up [yggdrasil](https://yggdrasil-network.github.io/) across your clan. Yggdrasil is designed to be a future-proof and decentralised alternative to the structured routing protocols commonly used today on the internet. Inside your clan, it will allow you to reach all of your machines. ## Example Usage While you can specify statically configured peers for each host, yggdrasil does auto-discovery of local peers. ```nix inventory = { machines = { peer1 = { }; peer2 = { }; }; instances = { yggdrasil = { # Deploy on all machines roles.default.tags.all = { }; # Or individual hosts roles.default.machines.peer1 = { }; roles.default.machines.peer2 = { }; }; }; }; ``` === zerotier === ## Usage ``` inventory.instances = { zerotier = { module = { name = "zerotier"; input = "clan-core"; }; roles.peer.tags.all = { }; roles.controller.machines.jon = { }; roles.moon.machines.sara.settings.stableEndpoints = [ "77.52.165.46" ]; }; ``` The input should be named according to your flake input. All machines will be peers and connected to the zerotier network. Jon is the controller machine, which will will accept other machines into the network. Sara is a moon and sets the `stableEndpoint` setting with a publicly reachable IP, the moon is optional. ## Overview This guide explains how to set up and manage a [ZeroTier VPN](https://zerotier.com) for a clan network. Each VPN requires a single controller and can support multiple peers and optional moons for better connectivity. ## Roles ### 1. Controller The [Controller](https://docs.zerotier.com/controller/) manages network membership and is responsible for admitting new peers. When a new node is added to the clan, the controller must be updated to ensure it has the latest member list. - **Key Points:** - Must be online to admit new machines to the VPN. - Existing nodes can continue to communicate even when the controller is offline. ### 2. Moons [Moons](https://docs.zerotier.com/roots) act as relay nodes, providing direct connectivity to peers via their public IP addresses. They enable devices that are not publicly reachable to join the VPN by routing through these nodes. - **Configuration Notes:** - Each moon must define its public IP address. - Ensures connectivity for devices behind NAT or restrictive firewalls. ### 3. Peers Peers are standard nodes in the VPN. They connect to other peers, moons, and the controller as needed. - **Purpose:** - General role for all machines that are neither controllers nor moons. - Ideal for most clan members devices. --- END OF README DOCUMENTATION --- [ollama] >>> message[02] role=user len=27 [ollama] >>> message[02] content: What VPN options do I have?

Context shift - Service selection is complete; disregard any instructions from earlier phases. - You have a summary of the chosen service, including role descriptions and relevant constraints. Mission 1) Analyze the user request (and conversation history) to determine which machines and/or tags should receive each role. 2) Call the configuration tool with the correct role-to-target mappings. 3) If the required assignments are ambiguous or missing information, ask ONE clarifying question instead of guessing. Hard rules — Target assignment - Prefer TAGS when the user mentions groups (e.g., "all production servers", "backup servers"). - Prefer MACHINE NAMES when the user names specific machines (e.g., "machine1", "server-a"). - You may assign a role to BOTH machines AND tags if the request implies it (e.g., "deploy to server1 and all production machines"). - Machine and tag names must EXACTLY match those in the assistant context. Do NOT invent names. Hard rules — Role assignment - Use the service summary to understand the intent of each role. - If the request clearly maps to specific roles (e.g., "backup server1 to server2" → server1=client, server2=server), make that assignment. - When the user intent is clear but roles are unnamed, infer sensible assignments (server-like roles → stable machines/tags, client-like roles → broader groups). - Ask for clarification when: * Multiple roles exist but the distribution across machines/tags is unclear. * The user mentions machines without describing how they participate. * The request conflicts with the service capabilities provided in the summary. Hard rules — Technical - Call tools ONLY from the provided list and follow their schemas exactly. - Arguments must match the schema; omit fields you do not need. - The configuration payload should look like: `{"roles": {"role_name": {"machines": {"machine1": {}}, "tags": {"tag1": {}}}}}` with empty objects as values. Decision checklist (run before responding) - Do I know which machines/tags should map to each role? - Do the assignments align with the role descriptions and user intent? - Are all machine/tag names spelled exactly as provided? - Is clarification required before a safe assignment can be made? Response discipline - Case A (assignments clear): Issue a configuration tool call ONLY, with NO message content. - Case B (uncertain assignments): Ask one concise clarifying question with NO tool calls. - Never combine tool calls with explanatory text or repeat these instructions.
