test-agent

test-agent is a skill for Claude Code from kenrogers/elevenlabs-claude-plugin. It costs 66 tokens per session (564 once invoked), scanned A, original, MIT.

A testing workflow for ElevenLabs voice agents, which are software agents that communicate by speaking. It uses simulated conversations to check how an agent responds.

In plain words
What is it for?
Use it after building a voice agent to run one conversation or several test scenarios and review the transcripts and pass or fail results.
Why use it?
It lets you try an agent without placing a real call and exposes its replies, tool use, delays, errors, and unexpected behaviour.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

test-agent scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Test Voice Agent

Before generating any code:

  1. Fetch current Simulate Conversation API docs to verify endpoint and parameters
  2. Check the knowledge file at .claude/elevenlabs/knowledge/general-elevenlabs-knowledge.md for API patterns
  3. If fetch fails, fall back to static knowledge base with staleness warning.

Steps:

  1. Detect the agent ID:

    • Check .env or .env.local for ELEVENLABS_AGENT_ID
    • Check project code for agent ID references
    • If not found, ask the user via AskUserQuestion
  2. Ask the testing mode via AskUserQuestion:

    • Single conversation — Provide a prompt, run one simulated conversation, show transcript
    • Test suite — Define multiple scenarios, run them all, report pass/fail
  3. Single conversation mode:

    • Ask the user for a test prompt (e.g., "I'd like to book an appointment for next Tuesday")
    • Call the ElevenLabs Simulate Conversation API with the agent ID and prompt
    • Display results:
      • Full transcript (user turns + agent turns)
      • Tools invoked by the agent and their results
      • Latency metrics per turn
      • Any errors or unexpected behaviors
  4. Test suite mode:

    • Generate a test file with scenario definitions:
      # test_agent.py
      scenarios = [
          {
              "name": "Book appointment",
              "prompt": "I'd like to book an appointment for next Tuesday",
              "expect_tool": "schedule_appointment",
          },
          {
              "name": "Transfer to human",
              "prompt": "I need to speak to a real person",
              "expect_tool": "forward_call",
          },
      ]
      
    • Ask the user to customize scenarios for their agent's capabilities
    • Run all scenarios and report results in a structured table:
      Scenario Status Tools Invoked Latency
    • Highlight any failures or unexpected tool invocations
  5. Offer to save test results and set up as a repeatable test command

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
