add-writerside-doc-moduleAdd a new external Writerside documentation source to kotlin-web-site via the TeamCity Kotlin DSL (as a sub-documentation source under KotlinWithCoroutines).
Add Writerside Doc Module is an agent skill from JetBrains/kotlin-web-site, published by the product's own GitHub organization. Add a new external Writerside documentation source to kotlin-web-site via the TeamCity Kotlin DSL (as a sub-documentation source under KotlinWithCoroutines). Use when wiring a new Kotlin/ docs repo into the site. Covers the VCS root, its registration, the checkout rules, the kr.tree TOC include, v.list version vars, and the README row. The old git-submodule approach is obsolete — do not use it.
Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Mobile, covering Android development. It works with Kotlin and Git. The repository describes itself as: The Kotlin programming language website. The licence is Apache-2.0.
6 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit 38512ff. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Shell commands in SKILL.md call:
mvnFrom the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
kotlinlang.orggithub.comFrom URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Add Writerside Doc Module loads about 1.9k tokens when it runs. Until then it costs about 106 tokens; SKILL.md has 633 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

.claude/skills/add-writerside-doc-module/SKILL.md (or your agent's skills folder).This skill wires an external documentation repository into kotlin-web-site so its pages are built and published as part of the main Kotlin docs site.
A doc source is now added entirely through the TeamCity Kotlin DSL as a
sub-documentation source nested under the existing KotlinWithCoroutines build (the
kotlin-reference module). There is no git submodule and no new build object for
this pattern — addSubDocumentation(...) handles checkout and snippet wiring.
The reference implementation is the kotlinx.serialization addition; mirror it.
Follow
.ai/guidelines.mdat all times (required byCLAUDE.md).
The user wants to publish docs from another repo (e.g. a new Kotlin/* library) on
kotlinlang.org, the same way coroutines, lincheck, dokka, api-guidelines, and serialization
are published.
Ask the user for (infer sensible defaults from the serialization example where possible):
| Input | Example | Notes |
|---|---|---|
| Object base name | KotlinxSerialization | Used as <base>Root for the VCS root object. |
| Display name | Kotlinx Serialization | Human-readable name of the VCS root. |
| Git SSH URL | git@github.com:Kotlin/kotlinx.serialization.git | Must be SSH (git@github.com:...). |
| Branch | refs/heads/master | Full ref. May be a custom docs branch. |
| Checkout dir | kotlinx.serialization | Dir name passed to addSubDocumentation. |
| Docs layout | default docs/ or custom (e.g. docs-website) | Determines whether custom rules are needed. |
| External tree file | serialization.tree | The .tree file that lives in the source repo. |
| origin / element-id | serialization | The module id used in the <include>. |
| TOC title | Serialization (kotlinx.serialization) | Shown in the site sidebar. |
| Version vars | kotlinxIoVersion=0.9.0, okioVersion=3.16.2 | Any %var% the docs reference; optional. |
| README row | page URL + repo URL | For the external-docs table. |
Make the edits in this order. Each one is anchored to an existing pattern; append the new entry alongside the others rather than reformatting the file.
File: .teamcity/documentation/vcsRoots/DocumentationRoots.kt
Append a new GitVcsRoot object after the last one (currently KotlinxSerializationRoot):
object <Base>Root: GitVcsRoot({
name = "<Display name>"
url = "<git SSH URL>"
branch = "<refs/heads/...>"
branchSpec = "+:refs/heads/*"
checkoutPolicy = AgentCheckoutPolicy.USE_MIRRORS
authMethod = uploadedKey {
uploadedKey = "default teamcity key"
}
})File: .teamcity/documentation/DocumentationProject.kt
Add a line after the last vcsRoot(...) call:
vcsRoot(<Base>Root)No import needed — the file already does import documentation.vcsRoots.*.
File: .teamcity/documentation/builds/KotlinWithCoroutines.kt
Add an addSubDocumentation(...) call inside the init { } block, alongside the existing
calls.
Default layout (repo has docs/ and docs/snippets/) — omit the rules arg; the
helper defaults to checking out .git + docs:
addSubDocumentation("<checkout dir>", <Base>Root)Custom layout — pass explicit checkout rules. Each rule is
+:<srcPathInRepo> => <pathInBuildCheckout>. You must include .git. Example
(serialization, whose docs live in docs-website):
addSubDocumentation("kotlinx.serialization", KotlinxSerializationRoot, """
+:.git => kotlinx-serialization/.git
+:docs-website => kotlinx-serialization/docs-website
""".trimIndent())The helper addSubDocumentation (defined at the bottom of KotlinWithCoroutines.kt, around
line 49) adds the VCS root with checkout rules and prepends a step that symlinks the
module's snippets into docs/snippets. Don't duplicate that logic — just call it.
File: docs/kr.tree
Add (or replace a placeholder topic= entry with) a <toc-element> that includes the
external tree. Place it near the other library includes (coroutines, lincheck):
<toc-element toc-title="<TOC title>">
<include from="<external tree file>" origin="<origin>" element-id="<element-id>"/>
</toc-element>from is the .tree filename that ships in the source repo; origin and element-id
identify the module.
File: docs/v.list
Add a <var> for each version the module's docs reference via %name%:
<var name="<name>" value="<value>"/>File: README.md
Add a row to the external-docs table (the "Source files ... are stored in separate repositories" table):
| [<Page name> docs](<page URL>) | [<repo name>](<repo URL>) |This is the exact diff produced by the reference change; use it as a template.

Add a new external Writerside documentation source to kotlin-web-site via the TeamCity Kotlin DSL (as a sub-documentation source under KotlinWithCoroutines). Add Writerside Doc Module is an agent skill from JetBrains/kotlin-web-site, published by the product's own GitHub organization. Add a new external Writerside documentation source to kotlin-web-site via the TeamCity Kotlin DSL (as a sub-documentation source under KotlinWithCoroutines).
Add Writerside Doc Module fits situations like: wiring a new Kotlin/ docs repo into the site; tasks that involve Android development.
Run `npx skills add JetBrains/kotlin-web-site --skill add-writerside-doc-module -a claude-code`. Or copy the skill folder (.claude/skills/add-writerside-doc-module in JetBrains/kotlin-web-site) into .claude/skills/add-writerside-doc-module in your project. Claude Code loads it when a task matches its description.
Run `npx skills add JetBrains/kotlin-web-site --skill add-writerside-doc-module -a codex`. Or copy the skill folder (.claude/skills/add-writerside-doc-module in JetBrains/kotlin-web-site) into .agents/skills/add-writerside-doc-module in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add JetBrains/kotlin-web-site --skill add-writerside-doc-module -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/add-writerside-doc-module, .gemini/skills/add-writerside-doc-module, .github/skills/add-writerside-doc-module and .opencode/skills/add-writerside-doc-module in your project.
Going by SKILL.md and its folder, Add Writerside Doc Module needs the command-line tools its instructions call (mvn).
SKILL.md names 2 domains. In commands or code: kotlinlang.org and github.com; the agent is likely to contact these when it follows the instructions. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Add Writerside Doc Module is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.9k tokens (SKILL.md is roughly 7.6k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with Add Writerside Doc Module: Improve Code Coverage (alexvanyo/composelife, 267 stars), Review (woocommerce/woocommerce-android, 319 stars), Codefmt (Amplicode/spring-skills, 128 stars) and Kt Search Release (jillesvangurp/kt-search, 155 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
