db-tools-mcp: Agent for Claude Code

.github/agents/extractor-maintainer.agent.md

Extractor Maintainer is an agent for Claude Code from urjeetpatel/db-tools-mcp. It costs 36 tokens per session (408 once invoked), scanned A, original, GPL-3.0.

Specialist instructions for modifying the dbtools extractor and its configuration-refresh flow. The covered code handles metadata caches and data extraction from SQL Server and Snowflake.

In plain words
What is it for?
Use them when changing extractor logic, refresh throttling, metadata cache schemas, SQL Server support, or Snowflake support.
Why use it?
They identify compatibility-sensitive areas where an apparently small change could affect cached data or database extraction behavior.

Agent for Claude Code

Written for Claude Code: user-invocable in frontmatter.

This is urjeetpatel/db-tools-mcp's own configuration. It tells Claude Code how to work on db-tools-mcp itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything db-tools-mcp configures →

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

Extractor Maintainer scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
