 6. For path handling, use `pathlib.Path` instead of string paths, and use `astrbot.core.utils.path_utils` to get the AstrBot data and temp directory.

+### KISS and First Principles
+
+Follow the KISS principle and reason from first principles during development. Start by identifying the real problem, required behavior, and smallest useful change before adding code. Do not pile on features, configuration switches, abstractions, dependencies, or compatibility layers unless they directly solve the current problem and have clear evidence of need.
+
+Prefer the simplest implementation that is correct, maintainable, and consistent with the existing codebase. If a broader design seems attractive, reduce it to the essential behavior needed now and leave optional expansion for a later, explicit requirement.
+
 ### No Unnecessary Helpers
 
 Prioritize inline implementation over abstraction. Avoid over-engineering and do not create helper functions unless absolutely necessary.

 ## Release versions
 
-1. Replace current version name to specific version name.
-2. Write changelog in `changelogs/`, you can refer to the full commit messages between the latest tag to the latest commit.
-3. Make and push a commit into master branch with message format like: `chore: bump version to 4.25.0`
-4. Create a tag and push the tag. For example: `git tag v4.25.0 && git push origin v4.25.0`
+Use a short-lived `release/*` branch for each release. The release branch is the stabilization area for version bumps, changelog updates, release-blocking fixes, and final validation only. Do not add unrelated features or broad refactors to a release branch.
+
+Prepare a release from a clean worktree with:
+
+```bash
+uv run python scripts/prepare_release.py 4.25.0
+```
+
+The script updates `pyproject.toml`, creates `changelogs/v4.25.0.md`, runs the required Python checks, and prints the remaining steps. Use these flags when needed:
+
+```bash
+uv run python scripts/prepare_release.py 4.25.0 --generate-api-client
+uv run python scripts/prepare_release.py 4.25.0 --dashboard-build
+uv run python scripts/prepare_release.py 4.25.0 --commit --push
+```
+
+Open a PR from `release/4.25.0` to `master`. The PR title must use the conventional commit format, for example `chore: bump version to 4.25.0`. After the release PR is merged, create and push the tag from the updated `master` branch so the tag points to the exact code that was merged:
+
+```bash
+git checkout master
+git pull --ff-only origin master
+git tag v4.25.0
+git push origin v4.25.0
+```
+
+For one-off release candidate branches, delete the release branch after the tag is pushed and verified. For maintained release lines, use a branch such as `release/4.25` and keep it until that line reaches EOL.
+
+```bash
+git branch -d release/4.25.0
+git push origin --delete release/4.25.0
+```

+
+- **Local Skills**: uploaded from the WebUI or placed under `data/skills/<skill_name>/SKILL.md`. These appear in the WebUI Skills management page.
+- **Plugin-provided Skills**: plugins can bundle Skills in their own `skills/` directory. They appear in the WebUI, but are managed by the plugin, so they cannot be deleted or edited from the Local Skills page.
+- **Sandbox preset Skills**: when the sandbox runtime is used, AstrBot reads Skills discovered inside the sandbox and provides them to the Agent.
+- **Workspace Skills**: Skills under the current session workspace, at `skills/<skill_name>/SKILL.md`. They are currently injected only in local runtime, where the path is usually `data/workspaces/{normalized_umo}/skills/<skill_name>/SKILL.md`.
+
+Workspace Skills are **request-scoped**. In local runtime, when AstrBot builds a request, it checks the current session workspace for a `skills/` directory and appends valid Skills to that request's Skill inventory. They are not shown in the WebUI Skills management page yet, and they are not written to the global Skills configuration.
+
+If a persona is configured to select specific Skills, that list filters only local, plugin-provided, and sandbox Skills. Workspace Skills are still discovered and injected as part of the current request. Workspace Skills are disabled only when the persona is explicitly configured to use no Skills.
+
+When multiple sources contain a Skill with the same name, request-time priority is:
+
+1. If the current persona is explicitly configured to use no Skills, no Skills are injected, including Workspace Skills.
+2. If the current persona selects a specific Skill list, that list does not filter Workspace Skills.
+3. The current session's Workspace Skill has the highest priority. If it has the same name as a local, plugin, or sandbox Skill, it overrides that Skill for the current request only.
+4. Local Skills take priority over plugin-provided Skills and sandbox-only Skills.
+5. Plugin-provided Skills take priority over sandbox-only Skills.
+6. Sandbox-only Skills are injected only when there is no local, plugin, or workspace Skill with the same name.
+
+If a local Skill has been synced into the sandbox, AstrBot treats it as the same Skill. In sandbox runtime, the request will prefer the path that is readable inside the sandbox. Workspace Skills are not automatically synced into the sandbox yet.

+## Skill 来源与优先级
+
+AstrBot 会从多个位置发现 Skills：
+
+- **本地 Skills**：通过 WebUI 上传或放置在 `data/skills/<skill_name>/SKILL.md`，会显示在 WebUI 的 Skills 管理页面中。
+- **插件内置 Skills**：插件可以在自己的 `skills/` 目录中提供 Skills。它们会显示在 WebUI 中，但由插件管理，因此不能在本地 Skills 页面删除或编辑。
+- **Sandbox 预置 Skills**：使用 sandbox 运行环境时，AstrBot 会读取沙盒中已发现的 Skills，并在请求时提供给 Agent。
+- **工作区 Skills**：当前会话 workspace 下的 `skills/<skill_name>/SKILL.md`。目前仅在 local 运行环境下注入，路径通常是 `data/workspaces/{normalized_umo}/skills/<skill_name>/SKILL.md`。
+
+工作区 Skills 是**请求级**能力：local 运行环境下，AstrBot 会在每次构建请求时检测当前会话 workspace 下的 `skills/` 目录，并把合法的 Skills 拼进本次请求的 Skills 清单。它们暂时不会显示在 WebUI 的 Skills 管理页面，也不会写入全局 Skills 配置。
+
+如果人格配置为“选择指定 Skills”，该列表只用于筛选本地、插件内置和 sandbox Skills；工作区 Skills 仍会作为当前请求的一部分被检测并注入。只有人格明确配置为“不使用任何 Skills”时，才会同时禁用工作区 Skills。
+
+当不同来源出现同名 Skill 时，请求中的优先级如下：
+
+1. 如果当前人格明确配置为“不使用任何 Skills”，则不会注入任何 Skills，包括工作区 Skills。
+2. 如果当前人格配置了指定 Skills 列表，该列表不会过滤工作区 Skills。
+3. 当前会话的工作区 Skill 优先级最高。同名时，它会覆盖本地、插件或 sandbox 中的同名 Skill，仅对当前请求生效。
+4. 本地 Skills 优先于插件内置 Skills 和 sandbox-only Skills。
+5. 插件内置 Skills 优先于 sandbox-only Skills。
+6. sandbox-only Skills 只会在没有同名本地、插件或工作区 Skill 时作为可用 Skill 注入。
+
+如果本地 Skill 已同步到 sandbox，AstrBot 会把它视为同一个 Skill；在 sandbox 运行环境下，请求中会优先使用 sandbox 内可读取的路径。工作区 Skills 暂不会自动同步到 sandbox。
