Adds agent and parentAgent to tool.execute.before, tool.execute.after,
and shell.env hook input. When agent A spawns agent B via the task tool,
hooks receive { agent: 'B', parentAgent: 'A' }. Top-level agents have
parentAgent undefined.
Both fields are optional — no existing plugin breaks.
Fixes anomalyco#15403

Issue for this PR
Fixes #15403
Type of change
What does this PR do?
Plugin hooks (
tool.execute.before,tool.execute.after,shell.env) have no visibility into which agent made a tool call or who delegated it. The session layer already tracks parent relationships (Session.createsetsparentIDintask.ts), but this never reaches plugins.This adds optional
agentandparentAgentfields to the three hook inputs. When agent A spawns agent B via the task tool, hooks receive{ agent: "B", parentAgent: "A" }. Top-level agents haveparentAgentundefined.The key line is in
task.ts—parentAgent: ctx.agent. Everything else is threading it through existingPlugin.triggercall sites.Same pattern as #13662 which added
sessionIDandcallIDtoshell.env.How did you verify your code works?
