Blame an entity
blameRead-onlyIdempotent
Find the most recent change to any semantic entity—column, function, env var, dependency—including author, time, reason, and current status (active, reverted, reopened).
Instructions
Most recent change to an entity — what changed, when, who, why.
Like git blame but for semantic entities (DB columns, functions, env
vars, dependencies) and AI agents. Also carries the derived decision
state: status (active / reverted / reopened) and
superseded_by (id of a later supersede overriding this change, or
""). If no history exists for the entity, returns {"error": "..."}
with protocol-level isError: false.
