What problem does it solve? Claude Code sessions run work at whatever model and effort the session happens to be set to, and no tool can change the session model in place. This Skill solves that by running a ptp command's real work in a sub-context with a model override, so each pipeline step executes at a deterministic model and effort rather than the session default. ## Core Features & Use Cases - Deterministic model dispatch: Accepts a <model>.<effort> target (or an effort.md line-1 reference) from the calling command and runs the work at exactly that setting. - Dual main-agent branches: Runs work either as a foreground Claude subagent with an injected effort directive (main=claude) or as a write-capable codex exec shell-out (main=codex), resolved via layered config. - Ordered contract: Enforces outer abort-preconditions, branch-guard handling, telemetry ledger bracketing, and a verbatim result relay of completed, refused, or needs-human-action terminal states. - Use Case: When /ptp:plan needs to run at opus.high but the session is on Sonnet, the command passes the target to this Skill, which spawns one foreground subagent at Opus with the high-effort directive and relays the plan result back. ## Quick Start Reference this Skill from a ptp command by passing a target like opus.high along with a description of the work the resolved main agent should perform.
