Read-only advisory agent for debugging and repeated failures. Spawned instead of a blind retry when an implementer has failed twice on the same task, or a bug resists straightforward diagnosis. Returns a root-cause diagnosis plus one concrete next step.
Forwarding shim for the loom codex implementation lane. Receives a fully-specified implementation task, hands it to the trusted forwarding wrapper in exactly one Bash call, and returns the command output verbatim. Never reads, edits, or implements anything itself.
Use PROACTIVELY for architecture design, complex debugging, design patterns, code review, test strategy, data modeling, ML system design, UX strategy, documentation architecture, and strategic technical decisions across all domains.
Primary implementation agent for all coding work - features, bug fixes, tests, data pipelines, ML training, infrastructure code, documentation, UI components, and queries. Handles routine implementation across all technical domains.
