Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00066 | $0.00564 |
| Opus 5 | $0.00033 | $0.00282 |
| Sonnet 5 | $0.00013 | $0.00113 |
| Haiku 4.5 | $0.00007 | $0.00056 |
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:
- Fetch current Simulate Conversation API docs to verify endpoint and parameters
- Check the knowledge file at
.claude/elevenlabs/knowledge/general-elevenlabs-knowledge.mdfor API patterns - If fetch fails, fall back to static knowledge base with staleness warning.
Steps:
-
Detect the agent ID:
- Check
.envor.env.localforELEVENLABS_AGENT_ID - Check project code for agent ID references
- If not found, ask the user via AskUserQuestion
- Check
-
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
-
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
-
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
- Generate a test file with scenario definitions:
-
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.

test-agent is a skill published in the GitHub repository kenrogers/elevenlabs-claude-plugin (3 stars, last pushed 5mo ago), licensed MIT. It adds 66 tokens to every session and 564 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
