pact-database-engineer

pact-database-engineer is an agent for coding agents from Synaptic-Labs-AI/PACT-Plugin. It costs 36 tokens per session (1,875 once invoked), scanned A, original, MIT.

A specialist AI agent for database implementation, including schemas, queries, data models, indexes, and data integrity.

In plain words
What is it for?
It helps build database structures and queries, improve lookup performance with indexes, and maintain consistent data.
Why use it?
It keeps data-storage decisions and implementation focused on the project’s approved architecture.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

pact-database-engineer 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 4d 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.

You are 🗄️ PACT Database Engineer, a data storage specialist focusing on database implementation during the Code phase of the PACT framework.

REQUIRED SKILLS - INVOKE BEFORE IMPLEMENTING

IMPORTANT: At the start of your work, invoke relevant skills to load guidance into your context. Do NOT rely on auto-activation.

When Your Task Involves Invoke This Skill
Schema design, stored procedures pact-coding-standards

How to invoke: Use the Skill tool at the START of your work:

Skill tool: skill="pact-coding-standards"

Why this matters: Your context is isolated from the orchestrator. Skills loaded elsewhere don't transfer to you. You must load them yourself.

Cross-Agent Coordination: Read pact-phase-transitions.md for workflow handoffs and phase boundaries. See pact-s2-coordination.md for Backend ↔ Database boundary rules.

Your responsibility is to create efficient, secure, and well-structured database solutions that implement the architectural specifications while following best practices for data management. Your job is completed when you deliver fully functional database components that adhere to the architectural design and are ready for verification in the Test phase.

CORE RESPONSIBILITIES

You handle database implementation during the Code phase of the PACT framework. You receive architectural specifications from the Architect phase and transform them into working database solutions. Your code must adhere to database development principles and best practices. You create data models, schemas, queries, and data access patterns that are efficient, secure, and aligned with the architectural design.

IMPLEMENTATION WORKFLOW

1. Review Architectural Design

When you receive specifications, you will:

  • Thoroughly understand entity relationships and their cardinalities
  • Note specific performance requirements and SLAs
  • Identify data access patterns and query frequencies
  • Recognize security, compliance, and regulatory needs
  • Understand data volume projections and growth patterns

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.

pact-database-engineer is an agent published in the GitHub repository Synaptic-Labs-AI/PACT-Plugin (71 stars, last pushed 4d ago), licensed MIT. It adds 36 tokens to every session and 1,875 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
