Developer Tools implementation checklist

Direct all functional output to stdout and all logging, warnings, or error messages to stderr to ensure pipe compatibility.

Implement specific non-zero exit codes for different failure categories (e.g., 1 for general errors, 64 for usage errors) to support CI/CD scripting.

Detect if the output is a TTY and automatically disable ANSI colors and interactive prompts when running in non-interactive environments like GitHub Actions.

Verify that --help, -h, --version, and -v flags are responsive at the root and for every sub-command.

Use non-blocking progress bars or spinners for long-running tasks, ensuring they are suppressed in non-TTY environments to prevent log bloating.

Include native TypeScript declarations (.d.ts) or Rust/Go source types; ensure no 'any' types exist in public-facing interfaces.

Ensure all write operations in the SDK support idempotency keys to prevent duplicate resource creation during network retries.

Hardcode an exponential backoff strategy for 429 (Rate Limit) and 5xx (Server Error) responses within the SDK core.

Export named error classes (e.g., UnauthorizedError, ValidationError) so consumers can use 'instanceof' checks rather than string parsing.

Set a global default timeout (e.g., 30 seconds) for all network requests to prevent hanging processes in user applications.

Build and test binaries for x64 and ARM64 architectures across Linux, macOS, and Windows using a matrix CI build.

Generate and publish SHA-256 checksums for all downloadable assets to allow users to verify file integrity.

Ensure the lockfile (package-lock.json, Cargo.lock, etc.) is committed to the repository to guarantee reproducible builds.

Populate 'repository', 'bugs', 'engines', and 'homepage' fields in the manifest file to ensure correct display on registries like npm or Crates.io.

Run a dependency tree audit to remove unused packages and verify that all production dependencies are strictly necessary to minimize install size.

Store API tokens and secrets using system-level secret stores (e.g., macOS Keychain, Windows Credential Locker) instead of plain-text config files.

Implement a configuration hierarchy where CLI flags override environment variables, and environment variables override local config files.

Implement regex filters to automatically redact authorization headers, tokens, and local file paths from debug logs before they are written to disk.

Integrate automated security scanning (e.g., Snyk, GitHub Dependabot) into the CI pipeline to block releases with known vulnerabilities.

Verify that the tool only requests the specific OAuth scopes or filesystem permissions required for its documented functionality.

Support a 'DO_NOT_TRACK' environment variable and a config flag to completely disable all telemetry collection.

Ensure telemetry only collects non-identifiable data such as OS type, CPU architecture, and tool version.

Implement a --debug or --verbose flag that provides a detailed execution trace for local troubleshooting without sending data to servers.

Display a one-time clear notice on the first execution explaining what data is collected and how to opt-out.

Implement an automated crash reporting system that prompts the user for consent before uploading stack traces.

Verify that every code snippet in the README or /examples directory compiles and runs against the current version.

Generate and distribute completion scripts for Bash, Zsh, and Fish shells.

Maintain a 'CHANGELOG.md' following 'Keep a Changelog' principles, categorized by Added, Changed, and Fixed.

Include a dedicated documentation section mapping common error messages to specific resolution steps.

Ensure every CLI command and SDK method has JSDoc, Rustdoc, or GoDoc comments for IDE intellisense support.
