Role policy

Role and subagent machinery is configuration and spawn parameters, not a fixed pipeline. Intra-harness role policy chooses which model, prompt, and tool surface fits a subagent or specialized pass. Veyyon is provider-agnostic: roles are not hard-coded provider assumptions.

What exists today

  • Subagents via the task tool (packages/coding-agent/src/task/executor.ts). /agents opens the live hub for active and persisted agent threads.
  • Explicit model policies, not a role-to-model matrix: the interactive model (/model), profile-wide subagent defaults and per-agent overrides under subagent, plus compaction.model. default is not a model or a role. Named roles (modelRoles, scoped per profile) let you pin specific work types. Edit roles under Settings → Model → Roles and subagent policy under Settings → Subagents. See Compaction & project memory and Models, roles, and profiles.
  • Plan / goal modes alter prompts and tool gating (/plan, /goal). The advisor watchdog (advisor.enabled and related settings, in packages/coding-agent/src/advisor/) is a background continuous-review mechanism rather than a mode you invoke; /advisor reports and configures it. See docs/handbook/src/features/advisor.md.
  • Addressed inter-agent messaging via the irc tool (packages/coding-agent/src/tools/irc.ts, packages/coding-agent/src/irc/bus.ts): send/wait/inbox/list ops over a process-global bus. send is fire-and-forget with delivery receipts; the bus wakes an idle recipient with a real turn, revives a parked one, or injects a non-interrupting aside into a busy one, the shipped analogue of wake-now-vs-defer message routing. wait (or send await:true) observes the recipient’s reply as a real turn. Gated by isIrcEnabled: available to every subagent and to a top-level session that can still spawn subagents.

No fixed role pipeline

Veyyon does not enforce a staged plan → implement → verify → repair handoff. It uses lighter-weight spawn, subagent-policy, and irc messaging patterns instead; you compose the stages yourself.

Pair role choice with execution-order prompts: explore → plan → edit → verify.
