How do review limits work?CodeRabbit enforces per-developer PR review limits within each organization. For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window. Please refer docs for additional details.

Estimated code review effort: 2 (Simple) | ~10 minutes Merge Risk: 🔵 Low · up to The documentation changes are mergeable with owner follow-up: the overview should state that config-file resolution and runtime completions are opt-in, and the migration table should qualify partial or unsupported clap compatibility so readers do not assume lossless behavior.

🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win
Identify the opt-in features in the overview.
The default installation in Lines 58-63 does not enable config or completions. The feature table also marks both features as non-default. State that config-file resolution and runtime shell completions require their respective features.

Instruction counts
No instruction-count regression above 1%. Only instruction counts gate. Wall clock is shown for context — on identical hardware it moves 4-20% run to run. Measured by tak — instruction-counted CLI benchmarks, stored in this repository's git notes. Shadow comparisonParsing

Documentation-only edits to the Rust framework pages; no runtime, API, or security behavior changes.
Overview
Marks the Rust framework docs as reviewed by dropping Draft banners across those pages, and rewrites the landing page around
usage-rsitself: typed CLIs, env/config, completions, and mise-scale speed/size versus clap.Moves clap-specific attribute mapping into the migration guide (including a Familiar field attributes table) and describes native
#[usage(...)]behavior on the args page without clap framing. Trims overlapping parser-overhead, dispatch-spec, and experimental compatibility-policy prose.Reviewed by Cursor Bugbot for commit d474e66. Bugbot is set up for automated code reviews on this repo. Configure here.
