MCP tools · 11 exposed · ~719 tokens

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →

Tool Tokens
book_outline ~38

The map of Open and Async: every section and chapter with a one-line TL;DR. Use it to find the right chapter for a topic.

Input schema present but exposes no named parameters.

No output schema declared.

No examples provided.

convert_meeting_to_async ~81

Given a meeting's purpose or agenda, propose the async equivalent: the artifact that replaces it, where it lives, who decides, and the deadline. Meetings are a point of escalation, not the default.

NameTypeReqDescription
agendaarrayAgenda items, if any.
purposestringyesWhy the meeting exists / what it's meant to accomplish.

No output schema declared.

No examples provided.

draft_decision_doc ~100

Turn a decision plus its options into a structured, async-friendly decision record (ADR): context, options with tradeoffs, the decision, and its reversibility. Write the decision down so others can follow it without a meeting.

NameTypeReqDescription
contextstringBackground: what forces this decision now.
decisionstringyesThe decision to be made, in one line.
optionsarrayCandidate options. Two or three is plenty.

No output schema declared.

handle_objection ~54

Map a common objection to open/async work ('async is slow', 'remote kills culture') to the book's reframe, with a chapter citation.

NameTypeReqDescription
objectionstringyesThe skepticism or pushback to address.

No output schema declared.

No examples provided.

run_async_standup ~69

Return a structured async-standup prompt a team can adopt in any chat or issue — replaces the daily sync standup with a written, searchable thread that respects every time zone.
