## What it does

The command enforces rigid standards for handling .NET packages. It mandates using `dotnet add package` and `dotnet remove package` instead of manually editing project files. Direct file edits to add or delete dependencies are forbidden.

Manual edits are reserved exclusively for updating version numbers. The workflow first checks if the specified version exists via `dotnet package search`. Next, it detects whether packages use centralized versioning in `Directory.Packages.props` or project-level `.csproj` files. After the edit, it runs `dotnet restore`. Changes revert automatically if restoration fails.

Host system requirements are specific. You must have the .NET SDK on your `PATH`, plus either `jq` or PowerShell installed to parse version verification queries.

## Install

### Claude Code (native platform)

1. **claude-code-templates**
```bash
npx claude-code-templates@latest --command project-management/nuget-manager
```

2. **Manually: put the files in place**
- File: `.claude/commands/nuget-manager.md` — Call it with /nuget-manager. For all projects use ~/.claude/commands/

### Codex

**Manually: put the files in place**
- File: `~/.codex/prompts/nuget-manager.md` — Call it with /prompts:nuget-manager. Codex marks this format deprecated in favour of skills

### GitHub Copilot

**Manually: put the files in place**
- File: `.github/prompts/nuget-manager.prompt.md`

### Gemini CLI

**Manually: put the files in place**
- File: `.gemini/commands/nuget-manager.toml` — Gemini stores commands as TOML: the prompt text goes into the prompt field

Where a file is given instead of a command, copy the files from the source to that path: https://github.com/davila7/claude-code-templates/tree/HEAD/cli-tool/components/commands/project-management/nuget-manager.md

## When to use it
- add NuGet packages via CLI without editing csproj XML manually
- remove project dependencies using standard dotnet commands
- verify package release versions before changing configuration files
- update versions accurately within Directory.Packages.props
- confirm project stability immediately via dotnet restore

## Example prompts
- Add package `Serilog` to the backend project
- Update `Newtonsoft.Json` to version 13.0.3 across the solution
- Remove `Newtonsoft.Json` from the WebApi project

# NuGet Manager

## Overview

This skill ensures consistent and safe management of NuGet packages across .NET projects. It prioritizes using the `dotnet` CLI to maintain project integrity and enforces a strict verification and restoration workflow for version updates.

## Prerequisites

- .NET SDK installed (typically .NET 8.0 SDK or later, or a version compatible with the target solution).
- `dotnet` CLI available on your `PATH`.
- `jq` (JSON processor) OR PowerShell (for version verification using `dotnet package search`).

## Core Rules

1.  **NEVER** directly edit `.csproj`, `.props`, or `Directory.Packages.props` files to **add** or **remove** packages. Always use `dotnet add package` and `dotnet remove package` commands.
2.  **DIRECT EDITING** is ONLY permitted for **changing versions** of existing packages.
3.  **VERSION UPDATES** must follow the mandatory workflow:
    - Verify the target version exists on NuGet.
    - Determine if versions are managed per-project (`.csproj`) or centrally (`Directory.Packages.props`).
    - Update the version string in the appropriate file.
    - Immediately run `dotnet restore` to verify compatibility.

## Workflows

### Adding a Package
Use `dotnet add [<PROJECT>] package <PACKAGE_NAME> [--version <VERSION>]`.
Example: `dotnet add src/MyProject/MyProject.csproj package Newtonsoft.Json`

### Removing a Package
Use `dotnet remove [<PROJECT>] package <PACKAGE_NAME>`.
Example: `dotnet remove src/MyProject/MyProject.csproj package Newtonsoft.Json`

### Updating Package Versions
When updating a version, follow these steps:

1.  **Verify Version Existence**:
    Check if the version exists using the `dotnet package search` command with exact match and JSON formatting. 
    Using `jq`:
    `dotnet package search <PACKAGE_NAME> --exact-match --format json | jq -e '.searchResult[].packages[] | select(.version == "<VERSION>")'`
    Using PowerShell:
    `(dotnet package search <PACKAGE_NAME> --exact-match --format json | ConvertFrom-Json).searchResult.packages | Where-Object { $_.version -eq "<VERSION>" }`
    
2.  **Determine Version Management**:
    - Search for `Directory.Packages.props` in the solution root. If present, versions should be managed there via `<PackageVersion Include="Package.Name" Version="1.2.3" />`.
    - If absent, check individual `.csproj` files for `<PackageReference Include="Package.Name" Version="1.2.3" />`.

3.  **Apply Changes**:
    Modify the identified file with the new version string.

4.  **Verify Stability**:
    Run `dotnet restore` on the project or solution. If errors occur, revert the change and investigate.

## Examples

### User: "Add Serilog to the WebApi project"
**Action**: Execute `dotnet add src/WebApi/WebApi.csproj package Serilog`.

### User: "Update Newtonsoft.Json to 13.0.3 in the whole solution"
**Action**:
1. Verify 13.0.3 exists: `dotnet package search Newtonsoft.Json --exact-match --format json` (and parse output to confirm "13.0.3" is present).
2. Find where it's defined (e.g., `Directory.Packages.props`).
3. Edit the file to update the version.
4. Run `dotnet restore`.
```
