Hand-maintained prose cleanup only. The generated README sections (dependency snippets, runnable examples, workspace/feature matrices) remain unchanged and continue to be source-of-truth through docs-sync.

Walkthrough

The README is restructured to clarify uselesskey as a test-fixture factory with explicit warnings about deterministic, test-only design. Content is reorganized to emphasize secret-scanner and push-protection workflows, simplify feature descriptions, and provide clearer feature-selection guidance with TOML configuration examples.

Changes

Cohort / File(s) Summary
Documentation & Positioning
README.md
Reframed library scope from generic test-fixture factory to explicit test-only artifact. Strengthened warnings about deterministic, predictable outputs. Reorganized "Why this exists" and "What problem it solves" sections to emphasize secret-scanner and cleanup workflows. Simplified fixture categories by replacing detailed format lists with "output shapes" and higher-level families (e.g., corrupted PEM variants). Added explicit feature-selection guidance with TOML configuration examples. Introduced dedicated "Token Fixtures" paragraph discouraging use for authorization or signature verification. Enhanced "Why this crate" section with "shape-first" framing and refined boundary bullets mapping to rustls, x509-parser, and rcgen use cases.

Summary of Changes

Hello, I'm Gemini Code Assist1! I'm currently reviewing this pull request and will post my feedback shortly. In the meantime, here's a summary to help you and other reviewers quickly get up to speed!

This pull request focuses on a comprehensive cleanup and refinement of the README.md file. The changes aim to enhance the clarity, conciseness, and overall user experience of the documentation by improving prose, reorganizing sections, and providing more explicit guidance on the library's features and appropriate use cases. The update ensures that the hand-maintained content is easy to understand, while automatically generated sections remain untouched.

Highlights

  • README Clarity and Structure: The README's introductory prose was significantly tightened and clarified, providing a more direct explanation of uselesskey's purpose and benefits. Key sections like 'The Problem' and 'Why Not Just...' were renamed to 'Why this exists' and 'What problem it solves' for improved readability.
  • Enhanced Feature and Output Descriptions: Descriptions for 'What you get' were refined, including a clearer breakdown into 'Output shapes' and 'Negative fixtures' subsections. The explanation of 'Token fixtures' was expanded to emphasize their role as shape-first artifacts rather than signing engines.
  • Improved Usage Guidance: Additional dev-dependencies examples were added to the 'Choose the smallest feature set' section, illustrating how to enable different feature combinations. Guidance was also added to the 'Feature Flags' section, directing users on when to consult the list versus the feature matrix.
  • Refined 'Why' and 'When NOT' Sections: The 'Why This Crate?' section was rephrased to 'Why this crate', and its sub-points were clarified. The 'When NOT to use this crate' section was updated with more precise language regarding production use cases for certificate validation and CA operations.

Code Review

This pull request significantly improves the clarity and structure of the README.md file. The new introduction, the "Choose the smallest feature set" section, and the refined explanations for token fixtures and design principles make the documentation much more accessible and user-friendly. The changes effectively tighten the prose and guide users better. I have one minor suggestion regarding stylistic consistency for the headings.

This change to sentence case is consistent with other new headings in this PR (e.g., ## Why this exists). However, many other headings in the document still use Title Case (e.g., ## Quick Start, ## Feature Flags, ## Ecosystem). To improve overall consistency, consider changing all headings to use the same style, preferably sentence case to align with the recent changes.

For example:

  • ## Quick start
  • ## Feature flags
  • ## Ecosystem
  • ## Community
  • ## Stability and versioning
  • ## License

- Line 58: Update the output-shapes list entry that currently reads "Certificate

"Certificate leafs and chains" in the README output-shapes section and update it
