Releases template v1.4.2. The generated project's LLM guidance was spread
across three .llm/ files that agents rarely read, and the core-over-std
preference was only advisory prose.

Changes

Slimmer agent guidance

Fewer files means agents actually read what remains.

  • Delete src/.llm/{general,performance,documentation}.md.
  • Inline the performance reminders into src/AGENTS.md, which now also
    says to print all verify output.

core over std enforced by Clippy

Rules that fail a build get followed.

  • Add [workspace.lints.clippy] std_instead_of_core = "warn" to the
    workspace Cargo.toml.
  • Member crates (src/{{project-name}}, src/cli) inherit it via
    [lints] workspace = true.
  • The benchmark now imports core::hint::black_box.

Tidy in verify

rust-llm-tidy runs last in .llm/verify.{sh,ps1}, after the publish
dry-run, and is skipped with an install hint when absent.

Versioning and docs

  • Bump the template marker to reloaded-templates-rust:1.4.2.
  • Add docs/migration/v1.4.2.md, linked from the nav and about.md.
  • Update the template test contract to assert the new guidance, lint
    inheritance, tidy placement, and absence of the deleted files.

- Delete `.llm/{general,performance,documentation}.md`; inline the
  performance reminders into `src/AGENTS.md`
- Run rust-llm-tidy last in `verify.{sh,ps1}` when installed
- Enforce `core` over `std` via the `std_instead_of_core` Clippy lint;
  benchmark imports `core::hint::black_box`
- Add v1.4.2 migration guide; bump version marker, nav, about, and the
  template test contract

Existing projects: follow docs/migration/v1.4.2.md.

Review Change Stack

Walkthrough

The template version changes to v1.4.2. Performance guidance moves into src/AGENTS.md, and optional rust-llm-tidy steps are added to verification scripts. Workspace lint configuration warns on std_instead_of_core, and member manifests inherit the settings. The benchmark uses core::hint::black_box. Tests, migration documentation, and MkDocs navigation are updated.

Merge Risk: 🟡 Moderate · up to 46b09

Generated projects will run a new tidy step during verification, but it can alter files after package validation has completed. The template’s migration validation can also miss individual references to removed guidance files. These issues should be corrected before release.

Check each deleted guidance path independently.

The current condition matches only the literal .llm/{general,performance,documentation}.md. It does not detect individual references such as .llm/general.md. A generated src/AGENTS.md can therefore contain a broken reference and still pass validation. Check each deleted path separately, while retaining the existing combined-form check.

Proposed fix
-            if ".llm/{general,performance,documentation}.md" in agents_text:
-                logger.error("✗ src/AGENTS.md still references deleted guidance files")
-                errors += 1

rust-llm-tidy --validate default apply mode official documentation

💡 Result:

The rust-llm-tidy tool is an opinionated, work-in-progress Rust linter designed for LLM-assisted workflows, available via the Sewer56/rust-llm-tidy repository [1]. It provides a unified command-line interface to perform several code-tidying operations, including reordering source items, visibility narrowing, documentation linting, and markdown/doc-comment fixing [1]. Regarding your specific request for --validate and apply mode: --validate: This flag is used to verify the configuration without actually processing any files [1]. This is particularly useful for CI environments to ensure the.rust-llm-tidy.yml configuration is valid before running operations [1]. Apply Mode: When the tool is run (often via the rust-llm-tidy-action in CI/CD pipelines), it can operate in an apply mode [2][3]. In this mode, the tool automatically applies fixes to the target files in place [2]. For example, when used in a CI workflow on a pull request, apply mode is typically configured to commit and push these automated fixes back to the PR branch [2][3]. Configuration: The tool optionally uses a.rust-llm-tidy.yml configuration file, discovered by walking up from the current directory [1]. This file allows you to specify include/exclude rules or skip entire files [1]. If no configuration file is present, the tool uses default settings [1][3].

💡 Result:

The rust-llm-tidy tool is a CLI utility written in Rust designed to lint and tidy codebases (specifically.rs and.md files) to improve compatibility or structure for LLM processing [1]. It provides specific flags for handling modifications and configuration validation [1]. Dry-Run Execution: To preview changes without applying them to your files, use the --dry-run flag [1]. For example: rust-llm-tidy --dry-run src/main.rs Configuration Validation: To verify the integrity of your configuration file (.rust-llm-tidy.yml) without processing any files, use the --validate flag [1]. This is particularly useful in CI environments to ensure the configuration is correctly formatted before running linting tasks [1]. rust-llm-tidy --validate Additional CLI usage details: - Default behavior: Running rust-llm-tidy without arguments processes files changed in the current git diff [1]. - Path specification: You can specify files or directories (e.g., rust-llm-tidy src) to process them recursively [1]. - Rule Selection: You can use --include and --exclude flags to run specific operations (e.g., fix, reorder, vis, lints) or skip them for a single invocation [1]. - Configuration Discovery: The tool automatically searches for a.rust-llm-tidy.yml file by walking up the directory tree to the repository root [1]. This can be overridden using the --config or --no-config flags [1].

Citations:


Use non-mutating tidy verification. Bare rust-llm-tidy processes changed files and applies fixes. Because it runs after the publish dry-run, verification can modify the working tree after validation. Replace it with rust-llm-tidy --dry-run in both scripts and both migration examples.
