Runtime description

The following is the tool's own agent-facing description, reproduced from the reviewed registry. It can contain implementation terminology; it does not expand the public stability commitment.

Read the agent-facing description

Build minimal context package within token budget. Modes: handles (references), compressed (content), full (all cached).
WORKFLOW: after ctx_read/ctx_compose, package focused context for handoff/subagent.
ANTIPATTERN: not for exploration — use ctx_compose/ctx_read first.
