Safe SQL Execution
supabase/supabase
A skill your agent uses whenever code will build, return, fetch, or execute SQL that runs against a user's real Postgres database — even when the request reads like an ordinary feature or bug fix…
Generate safe, read-only PostgreSQL queries from natural language.

What it does
Pg Data is an agent skill from tyrchen/geektime-bootcamp-ai. Generate safe, read-only PostgreSQL queries from natural language. Use when users need to query blogsmall, ecommercemedium, or saascrmlarge databases. Supports query generation, execution, and result analysis with confidence scoring.
Its SKILL.md is about 2.8k tokens, which your agent loads only when the skill is triggered. The skill folder holds 4 other files, including reference files (for example `references/blog_small.md`, `references/ecommerce_medium.md` and `references/saas_crm_large.md`).
It sits in Sales & Support, covering E-commerce operations and SQL. It works with PostgreSQL and SQL.
When your agent uses it
- Users need to query blogsmall
- Ecommercemedium
- Saascrmlarge databases
Example prompts
- “/pg-data”
Workflow steps
7 steps, taken from the step headings in SKILL.md.
- Analyze User Request
- Read Database Reference
- Generate SQL
- Validate SQL Safety
- Execute and Test
- Analyze Results and Score Confidence
- Return Results
What it can do on your machine
Read from SKILL.md and the folder at commit 4f1be7c. 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
Shell commands in SKILL.md call:
psql
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
Pg Data loads about 2.8k tokens when it runs, and up to ~15k if it reads all its reference files. Until then it costs about 61 tokens; SKILL.md has 937 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.
SKILL.md
Without a licence we can't republish the file, so here is its outline and opening line. It has 937 words (~2,805 tokens).
“Generate safe, production-ready PostgreSQL SELECT queries from natural language descriptions. This skill analyzes user requests, matches them to the appropriate database schema, generates secure SQL, tests execution, and validates results.”

When should I use Pg Data?
Pg Data fits situations like: users need to query blogsmall; ecommercemedium; saascrmlarge databases.
How do I install Pg Data in Claude Code?
Run `npx skills add tyrchen/geektime-bootcamp-ai --skill pg-data -a claude-code`. Or copy the skill folder (.claude/skills/pg-data in tyrchen/geektime-bootcamp-ai) into .claude/skills/pg-data in your project. Claude Code loads it when a task matches its description.
How do I install Pg Data in Codex?
Run `npx skills add tyrchen/geektime-bootcamp-ai --skill pg-data -a codex`. Or copy the skill folder (.claude/skills/pg-data in tyrchen/geektime-bootcamp-ai) into .agents/skills/pg-data in your project. Codex loads it when a task matches its description.
Can I use Pg Data in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add tyrchen/geektime-bootcamp-ai --skill pg-data -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/pg-data, .gemini/skills/pg-data, .github/skills/pg-data and .opencode/skills/pg-data in your project.
What does Pg Data need to run?
Going by SKILL.md and its folder, Pg Data needs the command-line tools its instructions call (psql).
Does Pg Data access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Pg Data safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Pg Data use?
No licence was found for Pg Data or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Pg Data use?
About 2.8k tokens (SKILL.md is roughly 11k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 12k tokens, read only when the agent opens those files.
What are the alternatives to Pg Data?
Skills that share tags, products or a category with Pg Data: Safe SQL Execution (supabase/supabase, 111k stars), Sql2er (ystemsrx/sql_to_ER, 188 stars), SQL Database Support for pREST (prest/prest, 4.6k stars) and Chdb SQL (vemetric/vemetric, 394 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
