What happened?

在 Home 首页用 @ 一次提及多个 skill发起新项目时,只有最后一个被提及的 skill真正激活,第一个被静默丢弃

根因定位:

• Home 创建项目走的是单数 skillId:apps/web/src/App.tsx:1493 createProject({ skillId: input.skillId, ... }) —— 不传 skillIds 数组。
• HomeHero 内部只维护单数 activeSkillId(apps/web/src/components/HomeHero.tsx:165),多个 mention 时后者覆盖前者。
• 服务端 primary skill 来自单数 effectiveSkillId(apps/daemon/src/server.ts:3517);"组合多 skill"只来自 skillIds 数组(server.ts:3553 → 渲染为 ## Composed skill 块),而 Home 路径根本不填这个数组。
• 对比:项目内 ChatComposer 的 @-mention 会把多个 skill 收进 skillIds 数组(apps/web/src/components/ChatComposer.tsx:1142),因此在项目里 @ 多个 skill 能全部组合生效 —— 两条路径行为不一致。

Steps to reproduce

1. 确保存在两个有效 skill
2. 在 Home 首页的输入框输入并提交:@skilla @Skillb。
3. 进入新创建的项目,查看该轮运行的实际 prompt
4. 观察:prompt 中只出现 ## Active skill — skillb;项目 .od-skills/ 下只 stage 了 skillb,skilla 完全缺席。

Expected behavior

在 Home 首页一次提及多个 skill 时,行为应与项目内聊天框 @-mention 多 skill 一致 —— 全部被激活(1 个 primary + 其余渲染为 ## Composed skill 块并 stage 到 .od-skills/)。

具体二选一(需产品决策):

• A(推荐,行为对齐): Home 创建路径也收集全部被提及的 skill,通过 skillIds 数组传给 daemon,使多 skill 组合生效。
• B(至少不静默丢失): 若 Home 明确只支持单 skill,则在 UI 上限制为单选(选第二个时替换并给出提示),避免用户以为两个都生效。

Hey @xxiaoxiong — thanks for picking this up.

Roughly how long do you think it’ll take: a few hours, 1–3 days, around a week, or longer?

[lefarcen]

Hey @xxiaoxiong, gentle check — still on this one? Anything blocking?

[lefarcen]

嘿 @xxiaoxiong，轻轻催一下：这个你还在跟进吗？如果有卡住的地方也可以直接说一声。

跟进中。两个活跃 PR（#6250 + #5818）等 reviewer 复评后立刻开始处理 #5824。预计 1-3 天内出第一版 PR——主要改动是让 HomeHero/App.tsx 走 skillIds 数组路径，让 Home 多 skill @-mention 与项目内 ChatComposer 行为一致。

[lefarcen]

PR #6333 is now open for this: it changes the Home flow to keep the mentioned skills in order, send the first one as the primary skillId, and forward the full skillIds[] array so the existing composed-skills daemon path can kick in again.

That matches the behavior already expected from the in-project composer path, so this issue will stay open until #6333 lands.

嘿 @xxiaoxiong，PR #6333 这边已经安静了 24h+，你这边是在继续修改，还是在等 reviewer 回来？

Re-opening this issue for community contribution because linked PR #6333 has had no author activity.

The PR has been left open as draft so @xxiaoxiong can resume later, and others may /claim this issue if they want to take it on.
