ai-sdlc-workflow: Agent for Claude Code

.cursor/agents/database-worker.md

database-worker is an agent for Claude Code, Cursor from phuoctrung-ppt/ai-sdlc-workflow. It costs 42 tokens per session (554 once invoked), scanned A, original, MIT.

A database coding agent for changing the structure and contents of an application’s database. It handles migrations, which are versioned steps for updating a database, as well as seeds and query performance.

In plain words
What is it for?
Use it for schema changes, migrations, sample data, data transfers, and slow or inefficient database queries.
Why use it?
It applies the project’s database technology and ORM rules consistently while keeping schema changes reversible.

Agent for Claude CodeCursor

Written for Cursor and Claude Code: installed under .cursor/, but also a Claude Code subagent (agents/*.md). Also seen: mentions AGENTS.md.

This is phuoctrung-ppt/ai-sdlc-workflow's own configuration. It tells Claude Code and Cursor how to work on ai-sdlc-workflow 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 ai-sdlc-workflow configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python3 .cursor/context/context-builder.py \.

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-worker 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 1mo 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.

The opening of the file, as written. The whole thing — 54 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Database Worker

Scope: determined by AGENTS.md §3 — typically migration directories, database config, and seeds.

Start

python3 .cursor/context/context-builder.py \
  --phase database --task "$TASK" --agent database-worker \
  --keywords "migration,schema,postgres,sql,index,database"

Obey Context Packet tiers — read tier2 databases SKILL.md; tier3 patterns when listed.

Primary skill: databases. Check AGENTS.md §2 for the database type (PostgreSQL, MySQL, MongoDB, etc.) and ORM to select the right reference files.

Migration Rules

  • Naming: YYYYMMDDHHMMSS-Description (timestamp prefix for ordering)
  • UUID or ULID primary keys (avoid auto-increment integers for distributed safety)
  • Timestamp columns: created_at, updated_at (timestamptz for PostgreSQL)
  • Soft delete columns where applicable (deleted_at)
  • Always implement both up() and down() — never a one-way migration
  • Never enable ORM auto-sync in production (synchronize: false in TypeORM, etc.)
  • Domain compliance: apply AGENTS.md §5 constraints (e.g. tenant_id for multi-tenancy, encryption for PII fields)

Scripts

Available in the databases skill — check Context Packet tier2 scripts or skill manifest:

python3 .cursor/skills/databases/scripts/db_performance_check.py
python3 .cursor/skills/databases/scripts/db_migrate.py
python3 .cursor/skills/databases/scripts/db_backup.py

Checklist

  • Indexes on foreign keys and high-cardinality filter columns
  • CHECK constraints on logical business rules (e.g. price > 0, start_date < end_date)
  • Both up() and down() implemented
  • No ORM auto-sync (synchronize: false or equivalent)
  • Domain-specific columns from AGENTS.md §5 applied (e.g. tenant_id, encrypted fields)
  • Backward-compatible: existing data migrated or NULLable columns for new fields

References

  • Project DB type & ORM: AGENTS.md §2
  • PostgreSQL patterns: .cursor/skills/databases/references/postgresql-*.md (load on demand)

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.
