handbook-discover
The handbook-discover skill inventories all available plugins in the Claude Code marketplace, displaying their installation status, versions, and component composition including skills, agents, commands, and servers. Use this when users need to browse marketplace offerings, audit installed plugins, or discover available extensions with filtering and detailed output options.

# Handbook Plugin Discovery
Run the discovery script to inventory all plugins in a Claude Code marketplace.
## Usage
```bash
python ${CLAUDE_SKILL_DIR}/scripts/discover.py # default: cc-handbook
python ${CLAUDE_SKILL_DIR}/scripts/discover.py --detailed # show component names
python ${CLAUDE_SKILL_DIR}/scripts/discover.py --json # machine-readable
python ${CLAUDE_SKILL_DIR}/scripts/discover.py --filter dotnet # filter by keyword
python ${CLAUDE_SKILL_DIR}/scripts/discover.py --uninstalled # only uninstalled
python ${CLAUDE_SKILL_DIR}/scripts/discover.py -m <marketplace> # other marketplace
python ${CLAUDE_SKILL_DIR}/scripts/discover.py -r <path> # explicit repo path
```
## Interpreting Results
- `[+]` — installed and enabled
- `[o]` — installed but disabled
- `[ ]` — not installed
- Component counts: `S`=skills `A`=agents `C`=commands `M`=mcp `L`=lsp `H`=hooks
## Follow-up Actions
For uninstalled plugins, suggest:
```bash
claude plugin install <plugin-name>@cc-handbook
```Analyze a task and produce an Architecture Decision Record with implementation steps.
Generate a .NET code coverage report scoped to files changed in the current branch. Runs tests with coverage collection and produces filtered HTML reports.
This skill should be used when investigating .NET project dependencies, understanding why packages are included, listing references, or auditing for outdated/vulnerable packages.
Run script-like CSharp programs using dotnet run file.cs. Use this skill when users want to execute CSharp code directly, write one-liner scripts via stdin, or learn about run file directives.
This skill should be used when working with Verify snapshot tests in .NET projects. Use when updating verified snapshots after intentional code changes, accepting new snapshots, discovering verify tests, or troubleshooting snapshot mismatches. Trigger phrases include "verify tests", "update snapshots", "accept snapshots", "verified files", ".verified.txt".

This skill should be used when the user wants to manage Git worktrees - creating worktrees from local or remote branches, listing active worktrees with details, deleting worktrees, or switching between worktrees. Ideal for working on multiple branches simultaneously without stashing changes.
Expert guidance for using the GitLab CLI (glab) to manage GitLab issues, merge requests, CI/CD pipelines, repositories, and other GitLab operations from the command line. Use this skill when the user needs to interact with GitLab resources or perform GitLab workflows.
