Plugins

SDD (Specification-Driven Development)

A methodology where code follows specifications. Every feature starts with a clear definition of what before diving into how.

Commands: /specify, /plan, /review, /drift, /document, /bootstrap-docs, /sdd-init

Skills: sdd-flow (full lifecycle orchestration)

Hooks: spec-guard, review-guard, subagent-inject, session-start

See sdd/README.md for full documentation.

codescout-companion

Companion plugin for codescout MCP server. Routes Claude to use codescout's symbol-aware tools instead of Read/Grep/Glob. Auto-detects codescout from .mcp.json, ~/.claude/.claude.json, ~/.claude/settings.json, or ~/.claude.json.

Hooks:

• session-start -- Tool guidance, memory hints, onboarding nudge, auto-reindex + drift warnings
• subagent-guidance -- Injects codescout guidance into all subagents (MCP server_instructions only reach the main agent)
• post-tool-guidance -- PostToolUse soft warnings when Read/Grep/Glob are used on source files, suggests codescout alternatives
• worktree-activate -- PostToolUse: creates write-guard marker + injects activate_project guidance after EnterWorktree
• worktree-write-guard -- PreToolUse: hard-blocks codescout write tools in worktrees until activate_project is called
• ce-activate-project -- PostToolUse: clears write-guard marker after activate_project fires

See codescout-companion/README.md for details and configuration.

Team Setup

Add to your project's .claude/settings.json so all team members get the plugins automatically:

{
  "extraKnownMarketplaces": {
    "sdd-misc-plugins": {
      "source": {
        "source": "github",
        "repo": "mareurs/sdd-misc-plugins"
      }
    }
  },
  "enabledPlugins": {
    "sdd@sdd-misc-plugins": true,
    "codescout-companion@sdd-misc-plugins": true
  }
}

When team members trust the repository folder, Claude Code automatically installs the marketplace and plugins.
