reticle vs coder_eval

reticle: Reticle puts a dev-only SDK inside your web or desktop app so a coding agent can look, act, observe and assert against the running app. Each check ends in a pass, fail or cannot-tell verdict with the network request, state change or console line that decided it and the source line to fix.; coder_eval: Coder Eval runs a real coding agent (Claude Code, Codex, Antigravity, OpenCode or Pi) in a sandbox against declarative YAML tasks and scores the files and commands it produced. It supports weighted 0.0-1.0 criteria, skill-trigger checks, A/B experiments and cost telemetry, and can gate CI on agent quality.
