Planning Pipeline — Skill Reference

Overview

The megaplan pipeline (packaged at megaplan/pipelines/planning/) is the built-in megaplan plan-production substrate. Its canonical registry identity is megaplan with the legacy alias planning → megaplan. It orchestrates the full prepare → plan → critique/gate/revise loop → finalize → execute → review lifecycle.

---

Gate verdict vocabulary

The gate stage emits a PipelineVerdict whose recommendation field is one of the following GateRecommendation literals:

Verdict	Meaning
proceed	Gate approved the plan; advance to finalize (and optionally execute).
iterate	Gate rejected the plan; re-enter the critique → revise loop.
tiebreaker	Evaluators are split; hand off to the tiebreaker stage for adjudication.
escalate	Quality ceiling reached at current tier; escalate to a higher-complexity model.

---

Robustness levels

Robustness controls the depth of the critique/gate loop and the number of evaluators engaged. Canonical names (accepted by --robustness / config):

Level	Alias(es)	Behaviour
bare	tiny	Single-pass, no gate loop. Fastest; for quick drafts.
light	—	One critique + revise round, minimal gate criteria.
full	standard	Standard gate loop (default). Balanced quality/cost.
thorough	robust	Extended gate loop, stricter criteria, more evaluators.
extreme	superrobust	Maximum depth, all evaluators enabled.

The default robustness when no --robustness flag is supplied is full.
