Automated safety checks
This skill passed all 6 checks. We read its files at one commit and looked for the things that make a skill dangerous to run — not for whether it works.
Declares what it does: passed
SKILL.md parses and declares a name and a description.
SKILL.md exists, its frontmatter parses, and it declares a name and a description.
No undeclared network calls: passed
Makes no network calls.
Every host the skill dials — from its scripts, its config endpoints or the commands it tells the agent to run — is either well-known package and API infrastructure or declared in its own frontmatter. Links in documentation are not counted.
No obfuscated payloads: passed
No encoded or obfuscated payloads.
No base64, hex or compressed blob is decoded and then executed, and no encoded shell commands.
No credential access: passed
Reads no keys, tokens, keychains or credential files.
Neither the code nor the SKILL.md instructions read SSH keys, cloud credentials, keychains, token stores, browser cookie databases or dotfiles that hold secrets.
No pipe-to-shell installers: passed
No pipe-to-shell or download-and-run installers.
No `curl … | sh` pattern, in the code or in the instructions, that runs code fetched at run time.

About this skill
The laravel:performance-select-columns skill instructs AI agents to optimize database queries by explicitly selecting only necessary columns rather than using SELECT *. This approach reduces data transfer overhead and improves application performance in Laravel applications.
When to use it
- Large tables: Querying massive datasets where fetching all columns causes unnecessary memory usage.
- API responses: Minimizing payload size when returning data to clients or third-party services.
- Slow queries: Diagnosing and fixing bottlenecks identified by slow query logs or profiling tools.
- Strict schemas: Enforcing discipline in codebases where specific column access is required for security or logic.
Key capabilities
- Generates optimized SQL queries that list specific column names instead of wildcards.
- Identifies redundant data retrieval within existing Laravel Eloquent models or raw queries.
- Suggests index usage improvements when combined with selective column fetching.
Example prompts
- "Refactor this Eloquent query to select only
user_id,name, andemailcolumns instead of loading the entire model." - "Optimize this database query for a table with 10 million rows by removing unnecessary columns from the SELECT statement."
- "Analyze these slow queries and rewrite them to fetch only the required fields for the view."
Tips & gotchas
Ensure you know the exact column names in your schema; incorrect selections will cause runtime errors. This skill works best when paired with other performance optimizations like indexing or query caching.
