Names the domain (BYOK API key configuration in Cursor) and lists specific providers (OpenAI, Anthropic, Google, Azure, custom models), but doesn't describe multiple concrete actions beyond 'configure'—no mention of steps like adding, updating, removing, or verifying keys.

Clearly answers both 'what' (configure BYOK API keys for multiple providers in Cursor) and 'when' (explicit trigger phrases listed). The 'Triggers on' clause serves as an explicit 'Use when' equivalent.

Includes a strong set of natural trigger terms that users would actually say, covering multiple provider variations ('cursor api key', 'cursor openai key', 'cursor anthropic key', 'own api key cursor', 'BYOK cursor', 'cursor azure key'). These are realistic search phrases.

Highly distinctive—the combination of BYOK, specific API providers, and Cursor creates a clear niche that is unlikely to conflict with other skills. The trigger terms are very specific to this particular configuration task.

Significantly verbose for a configuration guide. The token costs table, enterprise considerations, team key management, cost-saving strategies, security best practices, and detailed provider key formats are all information Claude already knows or that users can find in provider docs. The skill explains concepts like what BYOK is, what tab completion does, and includes approximate pricing data that will become stale. Much of this could be cut to focus on the Cursor-specific configuration steps.

The configuration steps are concrete with specific UI paths (e.g., 'Cursor Settings > Models > check Use own API key') and real URLs, which is good. However, there's no executable code or commands to verify the setup works, the Azure config block is a pseudo-config format rather than actual settings syntax, and the troubleshooting table describes fixes at a high level ('Regenerate key at provider') rather than giving specific steps.

Steps are listed in clear sequence for each provider, but there are no validation checkpoints. After entering a key, there's no explicit 'verify it works by doing X' step. The key rotation workflow is the closest to having validation ('Verify Chat/Composer work with the new key') but it's buried in a security section rather than integrated into the main setup flow.

This is a monolithic wall of text at ~180 lines covering setup, cost management, security, enterprise considerations, and troubleshooting all in one file with no bundle files. The cost tables, enterprise considerations, and security best practices should be split into separate referenced files. The external resource links at the bottom are helpful but don't compensate for the lack of internal content organization.
