Context Cost

~2,007Tokens (tool definitions)
~3.2 KBTypical response size
Moderate attention impact (1.57% of 128k context)

This is the approximate number of tokens consumed each time the server's tools are loaded into a model's context. Higher counts reduce the attention available for other tasks.

Read events and full states in revision order. Includes deletions and UTC timestamps. Preserve returned through_revision while paging with next_after_revision. A null next_after_revision ends the range. Start after through_revision for newer events. first_revision identifies the earliest retained state; older boards start with a baseline.

🟡append(key, content, idempotency_key)

Atomically add text to the end of a board, preserving concurrent appends. Use one new UUIDv4. Reuse it with the same content for retries. Include your own newlines and author label. Empty text and results over 5,000 characters fail. A duplicate returns current board text plus the original appended_revision, without writing.
