# Skill Group Composition

## Nearby Skills Inspected

- lov-skill-creator：命令迁移与通用结构；不拥有本业务结果。
- lov-branding-consistency：用户可见文案审校。
- lov-skill-publisher：已验证 Skill 的官网分发。

## Atomic Handoffs

本 Skill 接收请求与项目事实，交付为现有前端项目幂等接入 Lovinsp 并验证点击定位源码能力。文案审校只消费公开文本；发布器只消费校验后的 Skill 源，不接管业务执行。

## Overlap Decisions

旧命令按实际输入输出映射到本真源；不新增另一份重复业务实现。其他历史能力在本批次逐项比较，只有用户要求相邻结果时交接。

## Composition Decision

Single Skill：围绕同一结果的预览、执行和验证共享上下文；不把依赖工具或宿主适配误拆成 Kit。

# User Profile contract

Every Skill created by Skill Creator declares `user-profile/v1` in `skill.yaml`.
The contract connects independent sessions to one user-owned JSON Profile while
keeping the Skill source portable across users and brands.

## Shared shape

The host supplies the Profile through `SKILL_PROFILE_PATH` (or the runtime's
configured profile path). The stable shared scopes are:

- `user`: user identity, language, timezone, and other personal working defaults.
- `brand`: public brand facts, site, logo, tone, profile, and design guidance.
- `workspace`: project roots and output locations.
- `preferences`: shared preference values when the host stores them in the Profile.
- `skills.<skill_id>.profile`: Skill-specific defaults.
- `skills.<skill_id>.records`: durable decisions and preferences learned from
  direct user statements for this Skill.

The Profile may also use the runtime's canonical `identity` fields. Manifest
field aliases bridge `identity.*` and the portable `user.*` / `brand.*` names.

## Read on every run

1. Read the current request and project context.
2. Read the shared Profile and the `skills.<skill_id>` namespace.
3. Resolve values in this order: current request, project context, Skill records,
   shared preferences, shared user/brand Profile, safe defaults.
4. Keep `profile_scope` and field provenance available for the final result.

Do not copy resolved personal paths, brand values, or private records into the
committed Skill source.

## Persist directly stated values

When the user explicitly gives a value meant to survive later sessions, save it
immediately after the user statement and report the canonical path:

```bash
python3 scripts/profile_store.py record \
  --skill-id lov-example \
  --path records.subtitle_level \
  --value '"cet4"' \
  --confirm
```

For shared facts, use `--path brand.<field>` or `--path user.<field>`. The
script writes JSON atomically, preserves unrelated Profile data, increments a
numeric Profile revision when present, and never echoes the stored value.

Inferred information, credentials, tokens, cookies, and secret-like fields stay
out of durable records. If the user has not stated that a value should persist,
keep it in the current request context.

## Read the connected context

```bash
python3 scripts/profile_store.py read \
  --skill-id lov-example \
  --pretty
```

The result contains `user`, `brand`, `workspace`, `preferences`, `skill`, and
`records` scopes. A host using `skill-runtime/v1` also returns the same binding
as `profile_scope` and `profile_contract`.

## Compatibility

`--user-config` remains accepted by the Creator as a compatibility flag for old
invocations. The Profile contract is now always generated; users do not choose
an initialization mode.

#!/usr/bin/env python3
"""Read and persist a Skill's user-owned profile context.

The command keeps shared identity and brand facts in the profile root while
putting Skill-specific durable records under ``skills.<skill_id>.records``.
Writes require an explicit confirmation flag and use an atomic replacement.
