+description: Define default Node versions and manage project-specific versions with .nvmrc and auto-use flows.
+license: Complete terms in LICENSE.txt
+---
+
+## When to use this skill
+
+**ALWAYS use this skill when the user mentions:**
+- Setting a default Node version or alias
+- Creating or using a .nvmrc file
+- Auto-switching versions per directory
+
+**Trigger phrases include:**
+- "nvm alias default", "默认版本", ".nvmrc"
+- "auto use", "进入目录自动切换"
+
+## How to use this skill
+
+**CRITICAL: This skill is about defaults and .nvmrc.** Basic install/use belongs to nvm-usage-basics.
+
+1. Set the default alias or LTS target.
+2. Create or update .nvmrc with the required version or alias.
+3. Enable shell auto-use logic if requested.
+4. Verify switching behavior in a new shell session.
+
+**Important notes:**
+- Keep .nvmrc consistent across team repos to avoid version drift.

+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,

+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+description: Provide comprehensive guidance for installing and updating nvm from the official README, including install scripts, profile selection, and required environment variables.
+license: Complete terms in LICENSE.txt
+---
+
+## When to use this skill
+
+**ALWAYS use this skill when the user mentions:**
+- Installing nvm for the first time
+- Updating nvm using install.sh
+- PROFILE, NVM_DIR, or NVM_SOURCE configuration
+- Choosing curl vs wget installation
+
+**Trigger phrases include:**
+- "install nvm", "安装 nvm", "update nvm", "升级 nvm"
+- "install.sh", "PROFILE", "NVM_DIR", "NVM_SOURCE"
+- "curl 安装", "wget 安装", "脚本安装"
+
+## How to use this skill
+
+**CRITICAL: This skill only covers installation and update workflows.** Redirect usage, .nvmrc, or troubleshooting to the relevant nvm-* skills.
+
+1. Identify platform and shell (macOS, Linux, WSL, Alpine; bash/zsh/fish).
+2. Select the install path: script install, git install, or manual install.
+3. Follow the official install/update steps and note profile write behavior.
+4. Verify PROFILE selection and required environment variables.
+5. If upgrading, follow install script update or manual upgrade steps.
+
+**Important notes:**
+- The install script writes to the detected profile unless PROFILE is explicitly set.
+- For restricted networks, use the mirror/auth skill instead.

+# Installation
+
+## Instructions
+
+This example demonstrates how to install nvm on your system.
+
+### Key Concepts
+
+- Installation methods (curl, wget, manual)
+- Environment setup
+- Shell configuration
+- Verification
+
+### Example: Install using curl
+
+```bash
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
+```
+
+### Example: Install using wget
+
+```bash
+wget -qO- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
+```
+
+### Example: Manual Installation
+
+```bash
+# Clone the repository
+git clone https://github.com/nvm-sh/nvm.git ~/.nvm
+
+# Checkout latest release
+cd ~/.nvm
+git checkout v0.39.0
+
+# Source nvm
+. ./nvm.sh
+```
+
+### Example: Shell Configuration
+
+After installation, add the following to your shell profile:
+
+**For bash** (`~/.bashrc` or `~/.bash_profile`):
+```bash
+export NVM_DIR="$HOME/.nvm"
+[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
+[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"
+```
+
+**For zsh** (`~/.zshrc`):
+```zsh
+export NVM_DIR="$HOME/.nvm"
+[ -s "$NVM_DIR/nvm.sh" ] && \. "$NVM_DIR/nvm.sh"
+[ -s "$NVM_DIR/bash_completion" ] && \. "$NVM_DIR/bash_completion"
+```
+
+### Example: Verify Installation
+
+```bash
+# Reload shell configuration
+source ~/.bashrc  # or source ~/.zshrc
+
+# Verify nvm is installed
+command -v nvm
+
+# Check nvm version
+nvm --version
+```
+
+### Example: Custom Installation Directory
+
+```bash
+# Set custom NVM_DIR before installation
+export NVM_DIR="$HOME/custom/path/nvm"
+curl -o- https://raw.githubusercontent.com/nvm-sh/nvm/v0.39.0/install.sh | bash
+```
+
+### Key Points
+
+- Installation script automatically adds nvm to your shell profile
+- Reload your shell or source the profile after installation
+- Use `command -v nvm` to verify installation
+- Custom `NVM_DIR` can be set before installation
+- Manual installation requires sourcing nvm.sh in each shell session

+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.

+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and

+      Notwithstanding the above, nothing herein shall supersede or modify

+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or

+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A

+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a

+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.

+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain

+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+

+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:

+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and

+          that such additional attribution notices cannot be construed
+          as modifying the License.

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.

+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.

+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,

+- "--no-use", "手动加载"
+
+## How to use this skill
+
+**CRITICAL: This skill focuses on shell initialization and environment variables.** For installation or version usage, use other nvm-* skills.
+
+1. Identify the active shell and the correct profile file path.
+2. Add NVM_DIR and nvm.sh sourcing lines from the template.
+3. Add bash completion or optional config as needed.
+4. Start a new shell session and verify nvm loads.
+
+**Important notes:**
+- XDG_CONFIG_HOME changes the expected profile path.
+- Use --no-use when you only want nvm loaded without switching versions.

+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing

+
+## When to use this skill
+
+**ALWAYS use this skill when the user mentions:**
+- Deeper shell integration
+- Auto "nvm use" when entering a directory
+- Restoring PATH or deactivating nvm
+
+**Trigger phrases include:**
+- "shell integration", "深度集成", "auto use"
+- "PATH 恢复", "nvm deactivate"
+
+## How to use this skill
+
+**CRITICAL: This skill is for deeper shell integration and auto-switching.** Base shell loading belongs to nvm-setup.
+
+1. Pick the target shell and enable deeper integration steps.
+2. Add auto-use logic for directory changes.
+3. Restore PATH or deactivate nvm when needed.

+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or

+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or

+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+# Install Node.js Version
+
+## Instructions
+
+This example demonstrates how to install Node.js versions using nvm.
+
+### Key Concepts
+
+- Installing specific versions
+- Installing latest version
+- Installing LTS versions
+- Installing from aliases
+
+### Example: Install Specific Version
+
+```bash
+# Install specific version
+nvm install 18.17.0
+
+# Install and use immediately
+nvm install 18.17.0 --default
+```
+
+### Example: Install Latest Version
+
+```bash
+# Install latest Node.js version
+nvm install node
+
+# Install latest and set as default
+nvm install node --default
+```
+
+### Example: Install LTS Version
+
+```bash
+# Install latest LTS version
+nvm install --lts
+
+# Install specific LTS alias
+nvm install lts/hydrogen
+nvm install lts/iron
+```
+
+### Example: Install from Alias
+
+```bash
+# Install using alias
+nvm install stable
+nvm install iojs
+```
+
+### Example: Install and Reinstall npm
+
+```bash
+# Install version and reinstall npm
+nvm install 18.17.0 --reinstall-packages-from=current
+
+# Install and use npm version
+nvm install 18.17.0 --latest-npm
+```
+
+### Example: Install with Custom Options
+
+```bash
+# Install with custom npm version
+nvm install 18.17.0 --npm=9.0.0
+
+# Install without npm
+nvm install 18.17.0 --no-npm
+```
+
+### Key Points
+
+- Each version installs with its bundled npm
+- Use `--default` to set as default version
+- LTS versions are recommended for production
+- `node` alias refers to latest version
+- `--reinstall-packages-from` copies packages from current version

+# Use Node.js Version
+
+## Instructions
+
+This example demonstrates how to switch between Node.js versions using nvm.
+
+### Key Concepts
+
+- Switching versions
+- Using aliases
+- Using .nvmrc files
+- Version activation
+
+### Example: Switch to Specific Version
+
+```bash
+# Switch to specific version
+nvm use 18.17.0
+
+# Switch to latest version
+nvm use node
+
+# Switch to default version
+nvm use default
+```
+
+### Example: Use LTS Version
+
+```bash
+# Use latest LTS
+nvm use --lts
+
+# Use specific LTS alias
+nvm use lts/hydrogen
+nvm use lts/iron
+```
+
+### Example: Use from .nvmrc File
+
+```bash
+# Create .nvmrc file in project
+echo "18.17.0" > .nvmrc
+
+# Use version from .nvmrc
+nvm use
+
+# Auto-use when entering directory (requires shell integration)
+nvm use --silent
+```
+
+### Example: Use Alias
+
+```bash
+# Use version by alias
+nvm use stable
+nvm use my-alias
+```
+
+### Example: Verify Current Version
+
+```bash
+# Check current version
+nvm current
+
+# Or use node command
+node --version
+npm --version
+```
+
+### Key Points
+
+- `nvm use` activates a version in current shell
+- Version must be installed before use
+- `.nvmrc` files specify project Node.js version
+- Changes only affect current shell session
+- Use `nvm current` to check active version

+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+

+description: Verify nvm installation and diagnose PATH or profile loading issues after setup.
+license: Complete terms in LICENSE.txt

+
+## When to use this skill
+
+**ALWAYS use this skill when the user mentions:**
+- Verifying nvm, node, or npm versions
+- "nvm: command not found" after installation
+- PATH or profile not updated
+
+**Trigger phrases include:**
+- "nvm --version", "node -v", "npm -v"
+- "PATH 问题", "profile 未加载"
+- "安装后不可用", "verify installation"
+
+## How to use this skill
+
+**CRITICAL: This skill is for verification and initial diagnostics only.** For deeper platform issues, use the troubleshooting skills.
+
+1. Run verification checks for nvm, node, and npm.
+2. If commands fail, inspect profile loading and PATH order.
+3. Apply restore-path and common-problems guidance.
+4. Re-open a new shell session and re-check.
+
+**Important notes:**
+- nvm is a shell function, so the profile must load correctly.

+Important caveats and platform notes.
+
+### Notes
+- Source builds require a C++ compiler.
+- WSL works; native Windows does not.
+- `fish` is not supported by nvm itself.
+- Avoid Homebrew-managed nvm.
