Agent
Read-only impact-analysis subagent; aggregates the blast radius of one or more symbols across the indexed workspace and returns a merged must-update checklist of every call site that moves together.
Agent
Read-only call-chain tracing subagent; traces upstream callers / downstream callees of a symbol via the tree-lens index and reports the chain as an evidence-backed tree of nodes.
Agent
Read-only post-change verification subagent; given a set of just-modified files or symbols, checks index freshness and confirms every external caller of the changed definitions is still consistent, returning a per-item PASS/FAIL/UNVERIFIED verdict list.
