Lints a phone voice agent prompt and platform config before real callers reach it.
Score is being calculated.
Explain one Voice Agent Linter rule by id: why it exists, a bad and a good example, the fix, the platforms it applies to, and its sources with the date each was read. Static reference, no network access.
| Name | Required | Description | Default |
|---|---|---|---|
| rule_id | Yes | The rule id, for example no-live-date, vapi-nested-item-enum or no-ai-disclosure. |
Check a phone voice agent’s system prompt and, optionally, its config JSON (Vapi assistant, Retell agent or LLM, ElevenLabs agent, or OpenAI Realtime session) against rule-based checks learned on live calls. Finds: no live date and dates without a year; phone numbers, emails, URLs, hyphen ranges and long numbers the voice will misread; no spelling protocol or bare-letter spelling; instructions to pass as human, missing AI disclosure and missing recording notice; scripted tool start lines, stall phrases and silent or long openers; tools with no description, untyped or undescribed parameters, undefined required fields, unformatted date parameters and unstated results; Vapi nested item enums, flat analysisPlan keys, disabled plans and plans without the transcript; ElevenLabs Turbo stutter risk; no transfer or callback path and no end-call; placeholders, secrets, very long prompts and contradictory always and never rules. Each finding has a rule id, severity, the exact line (and JSON path for config), an excerpt, a specific message and the fix; disclosure and recording rules carry their legal citations with the date read. Returns a 0 to 100 score and a verdict. No model reads the input and nothing is stored. Informational, not legal advice.
| Name | Required | Description | Default |
|---|---|---|---|
| platform | No | Which platform the config is for. "auto" detects it from the JSON. | auto |
| config_json | No | The agent’s config as a JSON string, exactly as the platform exports it: a Vapi assistant, a Retell agent and/or LLM (or {"agent": ..., "llm": ...}), an ElevenLabs agent, or an OpenAI Realtime session or session.update event. | |
| min_severity | No | Only return findings at or above this severity: critical, high, medium or low. | low |
| first_message | No | The opening line the agent speaks, when it is not in the config. | |
| system_prompt | No | The agent’s system prompt, as plain text. Optional when config_json contains it. |
List every Voice Agent Linter rule with its id, title, default severity, category, what it reads (prompt, config or both) and the platforms it applies to. Filter by platform or category. Static reference, no network access.
| Name | Required | Description | Default |
|---|---|---|---|
| category | No | Only rules in this category. | |
| platform | No | Only rules that apply to this platform: vapi, retell, elevenlabs or openai_realtime. |
