The merge gate in execAgent silently dropped client-provided
projectSkills whenever activeDeviceId couldn't be resolved
(multi-device-no-bind, bound-device-offline, disableTools=true, no
DEVICE_GATEWAY_URL). The client having scanned `.agents/skills` /
`.claude/skills` and sent them up is itself proof that a device is
reachable now — gating availability on a multi-device-routing decision
conflated two concerns and produced "I sent skills but the model never
sees them" with no log to diagnose.

Drop the activeDeviceId precondition so projectSkills always populate
`<available_skills>`. Whether the readFile can actually resolve at
activation time stays gated at `serverRuntimes/skills.ts`, where a
missing `deviceFileAccess` naturally fails `activateSkill` instead of
silently hiding the option.

Also add a one-line merge log so future "why didn't my skill show up"
investigations land on the answer immediately.

# 🚀 LobeHub Release (20260528)

**Release Date:** May 28, 2026  
**Since v2.2.0:** 220 merged PRs · 15 contributors

> This cycle brings heterogeneous "platform agents" you can dispatch to
local or remote devices, a rebuilt onboarding flow, document-centric
chat, and a unified model-runtime error model — with new DeepSeek V4 and
Gemini 3.5 Flash support along the way.

---

## ✨ Highlights

- **More Hetero Agents (OpenClaw / Hermes)** — Create heterogeneous
agents and dispatch them to local or remote devices through the device
gateway, with an execution-target switcher in the composer and
persistent CLI sessions. (#15065, #15179, #15022)
- **iMessage on Desktop** — New iMessage setup and bridge on desktop,
plus bot attachments across every platform. (#15228, #15227, #15029)
- **Skills in the Composer** — Drag skill chips into chat, trigger
installed skills from the slash menu mid-line, and surface project-level
skills in the homogeneous agent runtime. (#15095, #15061, #15110)
- **New Models** — DeepSeek V4 Flash/Pro and Gemini 3.5 Flash across
providers, with thinking params for structured output and chat cost
estimates. (#15031, #15001, #15051, #14876)
