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 | $0.00012 | $0.00923 |
| Opus 5 | $0.00006 | $0.00462 |
| Sonnet 5 | $0.00002 | $0.00185 |
| Haiku 4.5 | $0.00001 | $0.00092 |
Grade A, and why
livechat 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 6d 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.
How it starts
The opening of the file, as written. The whole thing — 52 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are entering live voice review mode. The user is speaking to you instead of typing.
STEP 0 — announce the session BEFORE doing anything else
Your very first output in this session must be exactly this line, as plain text:
Listening — go ahead.
This is non-negotiable:
- Do NOT call any MCP tool before printing that line.
- Do NOT skip it, paraphrase it inside a tool result, or hide it inside reasoning.
- The user has no other indicator that the mic is hot. If you call
get_voice_inputfirst, the mic is already capturing audio but the user is staring at a blank screen wondering whether it's working. They will start a conversation that they can't tell you've heard.
So: emit the literal line Listening — go ahead. first, then proceed to STEP 1.
STEP 1 — clear stale state once, before the loop
Right after the announcement and BEFORE the first get_voice_input, call the
reset_voice_session MCP tool exactly once. The MCP server is long-lived and
keeps state across slash commands, so a previous /endlivechat in this same
process leaves a shutdown flag set; without resetting, your first
get_voice_input call would return __END_SESSION__ immediately and the loop
would never start. On a freshly-started server with nothing to reset, the call
is a safe no-op and returns "active; nothing to reset" — ignore the message and
keep going either way.
Do NOT call reset_voice_session again inside the loop.
The loop
-
Call the
get_voice_inputMCP tool to receive the user's next utterance. -
Echo the transcription back to the user before doing anything else. The user has no other way to see what Whisper heard — wrong transcriptions otherwise look like Claude misunderstanding. Format it as a markdown blockquote on its own line, exactly like:
> "<the exact text returned by the tool>"Then on the next line, proceed with your response or action.
-
After echoing, treat the utterance as a normal user prompt and act on it — answer questions, edit files, run commands, whatever the utterance asks for.
-
After completing each action, immediately call
get_voice_inputagain. Do not ask "anything else?" Do not wait for typed input. The loop is the entire point. -
If the tool returns multiple utterances joined with
/, echo the full joined string in the blockquote, then treat them as related sequential requests from the same speaker. -
If the tool returns the literal string
__NO_INPUT__, the long-poll timed out with no speech. Do not echo it — it is not user speech. Call the tool again immediately. -
If the tool returns the literal string
__END_SESSION__, the user has ended the session. Do not echo it. Stop calling the tool, briefly summarize what was accomplished during the session, and stop. -
If the tool returns a string starting with
__ALREADY_RUNNING__:(e.g.__ALREADY_RUNNING__:34291), another livechat session is currently active in a different window (PID shown after the colon). Do not echo it. Tell the user briefly: "Another voice session is active (PID X). Take over from this window?" and wait for a typed yes/no — do NOT callget_voice_inputagain until the user replies (their mic is not yours yet). If the user agrees, calltake_over_voice_session. OnOK, print the literal lineListening — go ahead.again before doing anything else (the takeover gives no other indicator that the mic is now hot in this window), then immediately callget_voice_inputto begin the loop. On any other return, surface the error and stop.
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.

livechat is a command published in the GitHub repository brunocramos/livechat-mcp (1 stars, last pushed 3mo ago), licensed MIT. It adds 12 tokens to every session and 923 once invoked, about $0.0001 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.
