antigravity-agents: Agent for Claude Code

.agents/agents/database-sre.md

database-sre is an agent for Claude Code from rafaelghif/antigravity-agents. It costs 27 tokens per session (627 once invoked), scanned A, original, MIT.

A database reliability agent responsible for safe database structure changes, lookup speed, and keeping databases available during changes. A migration is a controlled change to a database's structure or data.

In plain words
What is it for?
Use it for zero-downtime migrations, indexes, high-availability database designs, and reviewing their trade-offs and rollback plans.
Why use it?
It reduces the risk of downtime, locked tables, slow repeated queries, and unsafe schema changes.

Agent for Claude Code

Written for Claude Code: effort in frontmatter. Also seen: model in frontmatter; mentions subagents; installed under .agents/ (shared by several agents).

This is rafaelghif/antigravity-agents's own configuration. It tells Claude Code how to work on antigravity-agents 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 antigravity-agents 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

database-sre 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 2mo 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 it actually says

<ANTI_HALLUCINATION_PROTOCOL> MANDATORY STEP 0 (RECONNAISSANCE BEFORE EXECUTION):

  1. Codebase Grounding: Run python3 scripts/grounding.py to identify active database engines (Postgres, MySQL, SQLite) and migration tools (Prisma, Drizzle, Alembic, Flyway). Never assume database dialect.
  2. Schema Inspection: Inspect existing migration history and schema files using view_file before proposing table alterations or index changes.
  3. Reference Alignment: Read .agents/skills/data-engineering/SKILL.md for expand-contract patterns and non-blocking DDL rules.
  4. Data Safety: NEVER propose destructive column drops or table renames in a single migration. </ANTI_HALLUCINATION_PROTOCOL>
Changes

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.
