A scheduling and review tool for queued briefings from coding agents. It connects those requests to Google Calendar and records the decisions made during the briefing.

Use it to book urgent agent blockers for the next free slot, group other requests into review blocks, and save your decisions after each briefing.

It keeps agent questions and plans from interrupting your work one by one. Instead, it groups them into private calendar meetings at suitable times.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00070	$0.00877
Opus 5.5	$0.00028	$0.00351
Sonnet 5.5	$0.00014	$0.00175
Haiku 4.5	$0.00007	$0.00088

Security

Grade A, and why

huddle 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 1mo 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.

Huddle — book and run agent briefings

huddle-mcp is a coordination broker: parallel coding agents queue their plans and questions into it instead of interrupting the user. This skill is the orchestrator side — it turns that queue into real calendar events and records the user's decisions back. The broker never touches the calendar itself; you bridge it to whatever Google Calendar MCP the user has connected.

Prerequisites: both huddle-mcp and a Google Calendar MCP are connected.

Booking the queue

plan_meetings → returns unbookedMeetings, each with desiredWindow (asap | next-block), durationMinutes, and briefingMarkdown.
For each meeting, find a free slot via the calendar MCP (its suggest_time / list_events / freebusy tools) within the user's working hours:
- asap (blockers) → the soonest free slot today.
- next-block → the next review block (late morning / late afternoon); bundle, don't scatter. Create the event with:
- title = the meeting title,
- description = the meeting briefingMarkdown verbatim (this is the agenda),
- duration = durationMinutes,
- visibility = private — briefings carry plans and code into the calendar.
confirm_meeting with the meeting_id, the calendar event id the calendar MCP returned, and the start/end you booked.

Then tell the user what you scheduled and when — one line per meeting.

Each briefing description ends with a writable answer block (tkt_xxx → ), so the user can reply inside the event itself — that's the read-back path below.

Closing the loop — two ways, both unblock the waiting agents

A. The user answers inside the calendar event (e.g. they say "read my huddle answers", or you're checking after a booked briefing's time):

list_agenda → find booked meetings and their calendarEventId.
For each, fetch the event via the calendar MCP (get_event) and take its description — the user will have filled in the tkt_xxx → … lines.
Pass that description to ingest_answers. It parses every filled answer and resolves the matching tickets in one call, returning resolved + skipped.
Report what was resolved; the worker agents unblock on their next check_response. FYIs need no answer.

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.

huddle is a skill published in the GitHub repository marcoloco23/huddle-mcp (0 stars, last pushed 3mo ago), licensed MIT. It adds 70 tokens to every session and 877 once invoked, about $0.0003 per session on Opus 5.5. 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 2026-09-01.
