At a glance
A skill your agent uses when writing SQL queries — selects, joins, aggregations, window functions, or schema modifications.
- Writing SQL queries — selects
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
- Window functions
- Schema modifications
What it does
SQL Best Practices is an agent skill from aiming-lab/MetaClaw. Use this skill when writing SQL queries — selects, joins, aggregations, window functions, or schema modifications. Apply whenever SQL is needed to ensure correctness, safety, and performance.
Its SKILL.md is about 230 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Databases, covering SQL. It works with SQL. The repository describes itself as: 🦞 Just talk to your agent — it learns and EVOLVES 🧬. The licence is MIT.
When your agent uses it
- Writing SQL queries — selects
- Window functions
- Schema modifications
Example prompts
- “/sql-best-practices”
What it can do on your machine
Read from SKILL.md and the folder at commit 922caf3. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
SQL Best Practices loads about 234 tokens when it runs. Until then it costs about 53 tokens; SKILL.md has 84 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

SQL Best Practices
Query quality:
- Use
SELECT col1, col2— neverSELECT *in production code. - Use CTEs (
WITH) for readability instead of deeply nested subqueries. - Filter early: apply
WHEREbeforeJOINwhen possible to reduce data scanned. - Use
EXPLAIN/EXPLAIN ANALYZEto inspect query plans for slow queries.
Safety:
- Always use parameterized queries from application code — never string interpolation.
- Wrap destructive operations (
DELETE,UPDATE,DROP) in a transaction. - Test on a staging/dev environment before running on production.
Naming: snake_case for tables/columns, descriptive names, consistent pluralization.
