Optra Prism — Claude Code Plugin

PRISM intelligence plugin for Claude Code. Reviews prompts in real-time, captures telemetry for dashboard analytics, tracks session costs, and optionally routes requests through the Optra gateway for budget enforcement and guardrails.

Requirements

• Node.js 18+ (required for native fetch)
• Claude Code with plugin support
• An Optra API key (gck_*) — sign up at optra-ai.com

Quick Start

# 1. Add the marketplace
/plugin marketplace add grumatic/optra-prism-plugin

# 2. Install the plugin
/plugin install prism@optra-prism

# 3. Configure your API key
/prism:setup gck_YOUR_API_KEY

# 4. Restart Claude Code for OTEL telemetry to take effect

Alternative: Shell installer

curl -sL https://optra-ai.com/install-plugin.sh | bash -s -- gck_YOUR_KEY

Modes

Mode	What happens	Latency impact
Telemetry only (default)	OTEL export + prompt scoring + cost tracking. API calls go directly to Anthropic.	None
Full intelligence	All of the above, plus API calls route through Optra gateway for budget enforcement, guardrails, and full request/response logging.	Small hop

Choose your mode during /prism:setup. You can change it anytime.

What It Does

Three hooks run automatically:

Hook	Purpose
SessionStart	Validates API key, configures OTEL telemetry, optionally sets gateway routing
UserPromptSubmit	Reviews prompts for specificity/scope and captures them to ingest for scoring
Stop	Captures prompt/response pairs for analytics, tracks turns, warns on context bloat

Commands

Command	Description
/prism:setup	Configure API key, enable telemetry
/prism:status	Connection health, gateway toggle, session info
/prism:report	Weekly review — this week vs last week, PRISM grade, habits, worst prompts
/prism:help	List all available commands
/prism:uninstall	Remove plugin config and OTEL settings

Configuration

All service URLs (ingest, gateway, dashboard) are resolved automatically from your API key via the config endpoint (https://ingest.prism.optra-ai.com/v1/plugin/config). Only PRISM_INGEST_URL can be overridden for local dev:

PRISM_INGEST_URL=http://localhost:9005 claude

How It Works

/prism:setup gck_KEY
    │
    ├─→ Calls config endpoint → resolves URLs from API key
    ├─→ Caches config locally
    └─→ Syncs OTEL env vars to ~/.claude/settings.json (global)

Claude Code starts
    │
    ├─→ Reads ~/.claude/settings.json → OTEL env vars set at process init
    ├─→ SessionStart hook → validates key, optionally sets gateway URL
    │
    ├─→ User types prompt
    │   └─→ UserPromptSubmit hook → captures prompt to ingest
    │
    ├─→ Claude responds (OTel auto-exports: api_request, tool_result, etc.)
    │   └─→ Stop hook → captures response + turn counter
    │
    └─→ Next prompt...

Team Distribution

Add Prism to all team members by committing to your project's .claude/settings.json:

{
  "plugins": [
    {
      "source": "marketplace",
      "name": "grumatic/optra-prism-plugin"
    }
  ]
}

Each developer runs /prism:setup with their own API key.

Debugging

# Tail debug log
tail -f ~/.claude/plugins/data/prism-inline/debug.log

# Enable debug output in session
PRISM_DEBUG=1 claude

Auto-Updates

When installed via marketplace, the plugin updates automatically when a new version is released. You'll see a notification on session start when an update is applied.
