Task Complexity Routing

Original name

Original description

Use this skill when classifying a feature's complexity (mechanical, standard, architectural), when deciding which pipeline shape applies to a given feature, when escalating a task to a higher complexity level during execution, or when reviewing classification accuracy at retro. Triggers on FEATURE.md DoR review, sprint planning, task escalation via dispute or blocker, and RETRO.md classification accuracy sections. The complexity classification is **distinct** from the `mechanical:` flag in FEATURE.md frontmatter — they answer different questions and live under different rules. Complexity drives **pipeline shape** (which phases run); the mechanical flag drives **whether the PM does passe 2** (skipped if true). Both can be set independently. In v2 the agent tier system was simplified — there is one `red` agent and one `green` agent, no per-tier variants — so this skill no longer routes red/green models, only pipeline shape. Consult before setting a complexity field, before deciding whether to skip PM/architect/scaffolder phases, before downgrading a pipeline (forbidden), and when analyzing past sprints for routing calibration. Do NOT load this skill for routine implementation work — it is only needed at classification and routing decision points.
