d29cf651c7 fix(skills): declare activation triggers in descriptions and normalize version metadata (#2618)
* fix(skills): move version into metadata and normalize to semver

29 skills declared `version` at the top level of their frontmatter. The
schema reads it from `metadata`, so tooling that follows the schema either
misses it or has to special-case the top level.

Three motion skills also declared `version: 1.0`, which is not a valid
semantic version; normalized to `1.0.0`.

No behavioral change — frontmatter metadata only.

* fix(skills): state activation triggers in skill descriptions

148 skills described what they cover but never named the situation that
should trigger them. Since the description is what Claude matches against
to decide whether to load a skill, a description without a trigger makes
activation guesswork — the skill is either missed or loaded at the wrong
time.

Added a "Use when ..." clause to each, derived from the skill's own body
(most already stated the trigger under "## When to Use" or in the opening
line; that intent is now reflected in the frontmatter where it is actually
read from).

Descriptions were only appended to; no existing wording was removed.

* fix(skills): sync activation triggers into the Codex skill mirror

10 of the skills whose descriptions changed are also mirrored under
`.agents/skills/`, where the description was previously a verbatim copy.
Left alone, the two surfaces would disagree about when the skill applies.

Only the description line is synced; the Codex copies keep their reduced
frontmatter, since that validator accepts only name, description,
metadata, license, and allowed-tools.

* fix(skills): correct three activation clauses from review

- autonomous-loops: the clause pulled new loop work into a skill that its
  own body marks as a compatibility shim retained for one release. It now
  points at the canonical continuous-agent-loop instead.
- continuous-learning: the description carried the v1 routing directive
  twice; collapsed to one.
- homelab-pihole-dns: the clause fired on any broken home DNS. Narrowed to
  tasks that actually involve Pi-hole.

* chore: retain current main lockfile

Homelab Network Setup

Use this skill to design a home or small-lab network that can grow without needing a full rebuild.

When to Use

  • Planning a new home network or redesigning an ISP-router-only setup.
  • Choosing gateway, switch, and access point roles.
  • Designing IP ranges, DHCP scopes, static reservations, and DNS.
  • Preparing for future VLANs, Pi-hole, NAS, lab servers, or VPN access.
  • Troubleshooting a new network that has double NAT, unstable Wi-Fi, or changing server addresses.

How It Works

Start by separating device roles:

Internet
  |
Modem or ONT
  |
Gateway or router      NAT, firewall, DHCP, DNS, inter-VLAN routing
  |
Managed switch         wired clients, AP uplinks, optional VLAN trunks
  |
Access points          Wi-Fi only; ideally wired backhaul
Servers and NAS        stable addresses, DNS names, monitoring
Clients and IoT        DHCP pools, isolated later if VLANs are available

Pick a gateway that matches the operator, not just the feature checklist:

Option Best fit Notes
ISP router Basic internet only Limited control and often poor VLAN support
UniFi gateway Managed home network Good UI, ecosystem lock-in
OPNsense or pfSense Flexible homelab Strong VLAN, firewall, VPN, and DNS control
MikroTik Advanced network users Powerful, but easy to misconfigure
Linux router Tinkerers Document rollback before using as primary gateway

IP Plan

Avoid the most common default, 192.168.1.0/24, when you expect to use VPNs. It often conflicts with hotels, offices, and ISP routers.

Example small homelab plan:

192.168.10.0/24  trusted clients
192.168.20.0/24  IoT and media devices
192.168.30.0/24  servers and NAS
192.168.40.0/24  guest Wi-Fi
192.168.99.0/24  network management

Gateway convention: .1
Infrastructure reservations: .2 through .49
Dynamic DHCP pool: .50 through .240
Spare room: .241 through .254

Use home.arpa for local names. It is reserved for home networks and avoids the leakage/conflict problems of ad hoc names like home.lan.

nas.home.arpa
pihole.home.arpa
gateway.home.arpa
switch-01.home.arpa

DHCP And DNS

  • Use DHCP reservations for anything you SSH into, bookmark, monitor, or expose as a service.
  • Hand out the gateway as DNS until a local resolver is intentionally deployed.
  • If using Pi-hole or another DNS filter, give it a reservation first, then point DHCP DNS options at that address.
  • Keep a small static/reserved range per subnet so replacements do not collide with dynamic leases.

Cabling And Wi-Fi

  • Prefer wired AP backhaul over mesh when you can run Ethernet.
  • Use a PoE switch for APs and cameras if the budget allows it.
  • Label both ends of each cable and keep a simple port map.
  • Put the gateway, switch, DNS server, and NAS on UPS power if outages are common.

Examples

Beginner Upgrade

Goal: Keep the ISP router but stabilize a small lab.

  1. Set DHCP reservations for NAS, Pi, and any SSH hosts.
  2. Move local names to home.arpa.
  3. Disable duplicate DHCP servers on secondary routers or APs.
  4. Wire the main AP instead of relying on wireless backhaul.

VLAN-Ready Plan

Goal: Prepare for future segmentation without enabling it immediately.

  1. Choose non-overlapping /24 ranges for trusted, IoT, servers, guest, and management.
  2. Reserve .1 for the gateway and .2-.49 for infrastructure on every subnet.
  3. Buy a gateway and switch that support VLANs and inter-VLAN firewall rules.
  4. Document which SSIDs and switch ports will eventually map to each network.

Anti-Patterns

  • Double NAT without a reason or documentation.
  • Using 192.168.1.0/24 when VPN access is planned.
  • Dynamic addresses for NAS, Pi-hole, Home Assistant, or other service hosts.
  • Consumer routers repurposed as APs while their DHCP servers are still enabled.
  • Flat networks with cameras, smart plugs, laptops, and servers all sharing the same trust boundary.
