Estimated code review effort: 3 (Moderate) | ~25 minutes

Merge Risk: 🟡 Moderate · up to 0aafa

This documentation update expands guidance for traces and contributors, but users may share trace data without recognizing its sensitivity, and conflicting contributor instructions can lead to inconsistent PR and validation practices. Clarify these points before merging.

Clarify who may create pull requests.

AGENTS.md tells an agent to create a pull request when asked and add .agent-created-pr, but CONTRIBUTING.md says pull requests should be created by humans instead of AI agents. State whether the agent may create the pull request or may only prepare the branch and commits for a human.

Match the documented checks to CI.

The commands do not match .github/workflows/ci.yml. CI runs cargo clippy --workspace --all-targets -- -D warnings and cargo +nightly fmt --all -- --check. Update this requirement to prevent a local validation pass that still fails CI.

Based on learnings: repository validation includes workspace Clippy and nightly rustfmt checks.

Proposed wording
-- Make sure `cargo clippy --workspace` and `cargo +nightly fmt --all --check` check pass.
+- Make sure `cargo clippy --workspace --all-targets -- -D warnings` and `cargo +nightly fmt --all -- --check` pass.
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
- Make sure `cargo clippy --workspace` and `cargo +nightly fmt --all --check` check pass.
- Make sure `cargo clippy --workspace --all-targets -- -D warnings` and `cargo +nightly fmt --all -- --check` pass.
