 In the codex-rs folder where the rust code lives:
 
 - Crate names are prefixed with `codex-`. For example, the `core` folder's crate is named `codex-core`
-- When using format! and you can inline variables into {}, always do that.
+- Always inline `format!` arguments when possible (Clippy: https://rust-lang.github.io/rust-clippy/master/index.html#uninlined_format_args); prefer `format!("{value}")` over `format("{}", value)`.
 - Install any commands the repo relies on (for example `just`, `rg`, or `cargo-insta`) if they aren't already available before running instructions here.
 - Never add or modify any code related to `CODEX_SANDBOX_NETWORK_DISABLED_ENV_VAR` or `CODEX_SANDBOX_ENV_VAR`.
   - You operate in a sandbox where `CODEX_SANDBOX_NETWORK_DISABLED=1` will be set whenever you use the `shell` tool. Any existing code that uses `CODEX_SANDBOX_NETWORK_DISABLED_ENV_VAR` was authored with this fact in mind. It is often used to early exit out of tests that the author knew you would not be able to run given your sandbox limitations.
   - Similarly, when you spawn a process using Seatbelt (`/usr/bin/sandbox-exec`), `CODEX_SANDBOX=seatbelt` will be set on the child process. Integration tests that want to run Seatbelt themselves cannot be run under Seatbelt, so checks for `CODEX_SANDBOX=seatbelt` are also often used to early exit out of tests, as appropriate.
 - Always collapse if statements per https://rust-lang.github.io/rust-clippy/master/index.html#collapsible_if
-- Always inline format! args when possible per https://rust-lang.github.io/rust-clippy/master/index.html#uninlined_format_args
 - Use method references over closures when possible per https://rust-lang.github.io/rust-clippy/master/index.html#redundant_closure_for_method_calls
 - When writing tests, prefer comparing the equality of entire objects over fields one by one.
