What are otc-awesome-llm plugins?

The otc-awesome-llm repository provides a library of Claude Code plugins built specifically for the Optum Epic on Azure platform team. These plugins extend Claude Code with domain-specific capabilities ranging from Microsoft 365 automation to AI asset discovery and automated documentation generation.

Each plugin packages one or more of the following components:

• Skills -- Loaded contextually when Claude detects a matching trigger phrase (for example, "check my teams messages" activates the Teams Automation skill).
• Commands -- Slash commands you invoke directly, such as /ph-discover.
• Agents -- Subagent definitions that Claude delegates specialized work to.
• Hooks -- Event-driven scripts that run on session lifecycle events (for example, the Documentation Bot hook fires when a session ends and code was modified).

All plugins authenticate through the otc-awesome-llm marketplace registry and follow semantic versioning.

Plugin installation paths

Plugins are cached locally after installation. The default cache location is:

~/.claude/plugins/cache/otc-awesome-llm/<plugin-name>/<version>/

Plugin architecture

Every otc-awesome-llm plugin follows a standard directory structure inside its .claude-plugin/ manifest directory:

<plugin-name>/
  .claude-plugin/
    plugin.json          # Manifest with name, version, description, author
    plugin.json.j2       # Jinja2 template for manifest generation
  README.md              # Plugin overview and usage
  skills/                # Contextual skills (trigger-based)
    <skill-name>/
      skill.md           # Skill definition with frontmatter triggers
      scripts/           # Supporting Python/JS scripts
  commands/              # Slash commands (user-invoked)
    <command-name>.md    # Command definition with frontmatter
  agents/                # Subagent definitions
    <agent-name>.md      # Agent personality and instructions
  hooks/                 # Lifecycle event hooks
    <event-name>.sh      # Executable hook script
    <event-name>.md      # Hook definition with frontmatter

How plugins load at runtime

1. Claude Code reads ~/.claude/plugins/installed_plugins.json at startup.
2. For each installed plugin, it loads the .claude-plugin/plugin.json manifest.
3. Skill triggers are registered so that matching user phrases activate the skill.
4. Commands are registered as available slash commands.
5. Hooks are bound to their declared lifecycle events (for example, Stop).
6. Agents are made available for subagent delegation.

Plugin versioning

All otc-awesome-llm plugins share the repository's semantic version. When the repository releases a new tag (for example, 7.4.1), all plugins within it are published at that version. Individual plugins do not version independently.
