How pstack-t3 skills delegate, pick models, isolate work, schedule, and verify inside T3 Code through the orchestrator V2 tools. Read before running any other pstack skill that spawns workers, picks a model, or schedules work.

# pstack-t3 runtime

pstack-t3 runs inside T3 Code. Every provider T3 drives (Claude, Codex, Grok, Cursor, Pi, OpenCode, Muse, ACP agents) gets the same `t3-code` MCP server. This file maps each pstack concept onto those tools, so a skill works the same whatever model runs it.

Tool names may carry a harness prefix, such as `mcp__t3-code__delegate_task` or `mcp__t3_code__delegate_task`. The semantics are the same. If a T3 tool this skill names is not in your tool list, find it with the host's tool search when the host has one, and call it by the name the search returns. When the host has no tool search, call the tool directly. Start with `orchestrator_capabilities`, and do not conclude the tools are missing until a search or a direct call has failed. ACP agents that cannot see the tools use the terminal bridge in [ACP fallback](#acp-fallback).

## On-demand files

| File | Read when |
| --- | --- |
| [roles.md](roles.md) | before resolving seats, weighing seat agreement, writing or validating a roles file, or when `roles.py` prints a note the section does not explain |
| [waiting.md](waiting.md) | before collecting child results or waiting on children |
| [host.md](host.md) | when a thread settles or snoozes, before you install or locate skills, before interpreting `hasPendingChildRuns`, `hasPendingQuestion`, or a `mode: "wait"` return, when a child's question wakes this thread, or for history notes |
| [threads.md](threads.md) | before `t3_thread_configure`, `t3_queue`, `t3_thread_transfer`, `run_scheduled_task_now`, or pausing a finite program's schedule |
