+# Skills
+
+One skill per CI Server area, following `knowledge/document-map.md`. Nested skill folders
+are not used for grouping; group tasks inside each skill instead:
+
+```
+<area>/
+├── SKILL.md       # frontmatter (name, description with task keywords) + task index
+├── tasks/         # one file per task
+└── reference/     # area-specific details
+```
+
+The `description` in `SKILL.md` decides when Claude uses the skill. List the words users
+will actually say.

+# CI Server Engineering Assistant
+
+You act as an experienced Yokogawa CI Server engineer. Users describe what they want to do
+in CI Server; you do it (or guide them) using the knowledge in this repo.
+
+- **Target version:** CI Server **R1.03**. Say so if a request depends on another release.
+- **Language:** use the English (EN) manuals only.
+
+## Where to look, in order
+
+1. **Skills**: `.claude/skills/<area>/`. There is one skill per CI Server area (e.g. Edit Module,
+   Alarm Management). `SKILL.md` is an index; open only the task file you need.
+2. **Shared knowledge**: `knowledge/`. The document map, glossary, known issues and
+   system-wide concepts.
+3. **Examples**: `examples/`. Verified, working artifacts to copy and adapt.
+4. **The manuals**: if the repo does not cover it, look it up in the EN PDFs. They are **not**
+   in this repo. Default location: `C:\Users\Public\Yokogawa\tls\doc\EN\`. Use
+   `knowledge/document-map.md` to find the right manual by IM number.
+
+If the answer comes from the manuals rather than the repo, say so and name the manual
+(IM number and section). Never guess CI Server behavior; say what you could not verify.
+
+## Conventions
+
+- Summarize manual content in your own words; never copy manual text into the repo.
+- Cite sources (IM number + section) and the version in every knowledge or task file.
+- Mark whether content is **verified** on a real system or **from docs** only.
+- Never modify the manual folder.

 # ci-server-config
 
-Configuration for the CI server.
+A knowledge base that lets Claude Code work as a Yokogawa CI Server (R1.03) engineer.
+Open this repo in Claude Code and describe what you want to do in CI Server.
+
+## Layout
+
+| Path | Contents |
+|---|---|
+| `CLAUDE.md` | Always-loaded instructions: role, version, where to look |
+| `.claude/skills/` | **How to do things.** One skill per CI Server area; each task is its own file |
+| `knowledge/` | **Shared reference.** Document map, glossary, known issues, cross-area concepts |
+| `examples/` | Verified, working artifacts (class descriptions, reports, scripts) |
+| `tools/` | Helper scripts Claude can run (e.g. searching the manuals) |
+
+## Prerequisites
+
+The CI Server EN manuals must be available locally. They are not stored in this repo.
+The default location is `C:\Users\Public\Yokogawa\tls\doc\EN\`; see
+`knowledge/document-map.md` if yours is different.
+
+## Contributing
+
+- Add task knowledge under the matching skill: `.claude/skills/<area>/tasks/<task>.md`,
+  and add a row to that skill's `SKILL.md` index.
+- Write in your own words, cite the manual (IM number + section) and the version, and mark
+  the content as verified or from docs.
