Agent
Trace feature implementations through the codebase and return a compact map — entry points, call chain, 3-5 essential files with file:line references. Dispatched from up:uexecute when a codebase question needs answering.
Agent
Implement one trivial phase of an approved plan — typos, one-line fixes, mechanical renames, doc/copy edits, lint/import re-orders. Same procedure as up:implementer but on Sonnet for cost. Dispatched per-phase from up:uexecute when the phase is unambiguously trivial.
Agent
Implement one phase of an approved plan — code, tests, commit. Default implementer for complex phases (multi-file, new logic, TDD, interface changes). Dispatched per-phase from up:uexecute.
Agent
General-purpose deep research. Decomposes a query, investigates systematically across the web, library docs, and the current codebase, returns a synthesized answer shaped by the question. Use when the main agent needs external knowledge beyond what Context7 or a quick web search gives.
Agent
Independent code review against a task's Plan, Invariants, and Assumptions. Stance — the future maintainer's audit: sit in the chair of the next person to touch this code and ask 'what will bite us later?' at the decision level. Single dispatch. Confidence-filtered (≥80), severity-tiered, with optional Scope flag.…
Agent
Draft a session-handoff summary so a fresh agent can continue with zero conversation context. Locates the current session's JSONL transcript by grepping for a distinctive phrase, reads it, and merges with repo state. Never writes to disk.
