Launches subagents to parallelize workflows.
{{#if asyncEnabled}}
- Results are delivered automatically when complete.
- The tool result lists the assigned task ids (e.g.
AuthLoader) — those are the live agent ids.
{{#if ircEnabled}}
- Coordinate with running tasks via
irc using those ids. job cancel terminates a task and cannot carry a message — only use it for stalled/abandoned work.
- If genuinely blocked on completion, wait with
job poll; otherwise keep working.
{{else}}
- If genuinely blocked on completion, wait with
job poll; otherwise keep working.
- Use
job list to snapshot manager state; cancel: [id] only to actually stop a stuck task.

Subagents have no conversation history, but they can reach you and their siblings live via the irc tool. Front-load every fact, file path, and direction they need in {{#if contextEnabled}}context or assignment{{else}}each assignment{{/if}}.

{{/if}}
- `agent`: agent type for all tasks
- `tasks`: tasks to execute in parallel
- `.id`: CamelCase, ≤32 chars
- `.description`: UI label only — subagent never sees it
- `.assignment`: complete self-contained instructions; one-liners and missing acceptance criteria are PROHIBITED
{{#if contextEnabled}}- `context`: shared background prepended to every assignment; session-specific only{{/if}}
{{#if customSchemaEnabled}}- `schema`: JTD schema for expected structured output (do not put format rules in assignments){{/if}}
{{#if isolationEnabled}}- `isolated`: run in isolated env; use when tasks edit overlapping files{{/if}}
- **Maximize batch width.** Spawn the widest parallel set the work decomposes into. NEVER spawn a single-task batch for divisible work, or defer work that could have been concurrent.
- NEVER assign tasks to run project-wide build/test/lint. Caller verifies after the batch.
- **Subagents do not verify, lint, or format.** Every assignment MUST instruct the subagent to skip all gates and formatters. You run them once at the end across the union of changed files — avoids redundant runs and racing formatter passes.
- No globs, no "update all", no package-wide scope. Fan out.
- Do not concern yourself with how agents might overlap on certain actions. Never use it as an excuse to go slower: they can resolve collisions in real-time with the harness facilities.
- Pass large payloads via `local://` URIs, not inline. {{#if contextEnabled}} (other than the context){{/if}}
{{#if contextEnabled}}- Put shared constraints in `context` once; do not duplicate across assignments.{{/if}}
- Prefer agents that investigate **and** edit in one pass; only spin a read-only discovery step when affected files are genuinely unknown.
{{#if ircEnabled}}
Test: can task B run correctly without seeing A's output? If no, sequence A → B — **unless** B can reasonably ask A for the missing piece over `irc`. Live coordination beats a serial waterfall when the contract is small and easy to describe in a DM.
Still sequence when one task produces a large, evolving contract (generated types, schema migration, core module API) the other consumes wholesale — IRC round-trips do not replace a finished artifact.
Parallel when tasks touch disjoint files, are independent refactors/tests, or only need occasional clarification that can be resolved peer-to-peer.

Goal ← one sentence: what the batch accomplishes
Constraints ← MUST/NEVER rules and session decisions
Contract ← exact types/signatures if tasks share an interface
{{/if}}
# Target ← exact files and symbols; explicit non-goals
# Change ← step-by-step add/remove/rename; APIs and patterns
# Acceptance ← observable result; no project-wide commands

Agent spawning is disabled for this context.
