databases

databases is a skill for Kiro from ihatesea69/kiro-kit. It costs 34 tokens per session (365 once invoked), scanned A, original, MIT.

Guidance for designing and managing data stores such as PostgreSQL, MongoDB, and Redis. It covers how data is structured, queried, migrated, indexed, backed up, and served.

In plain words
What is it for?
It helps design schemas, write SQL and aggregation queries, improve query speed, plan migrations, configure replication and backups, and choose between relational and non-relational databases.
Why use it?
It helps avoid poorly designed data layers, slow queries, unsafe migrations, and storage choices that do not fit the application's needs.

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

databases 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.

The scan reads SKILL.md. This mod also ships 6 executable files (scripts/db_backup.py, scripts/db_migrate.py, scripts/db_performance_check.py, …), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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

Databases

Activate this skill when working with database design, queries, migrations, or optimization.

When to Use

  • Designing database schemas and relationships
  • Writing complex queries or aggregation pipelines
  • Optimizing slow queries with indexes and execution plans
  • Planning and executing database migrations
  • Configuring replication, backups, or sharding
  • Choosing between SQL and NoSQL for a use case

PostgreSQL

  • Use EXPLAIN ANALYZE for query optimization
  • Create indexes based on WHERE, JOIN, and ORDER BY patterns
  • Use partial indexes for filtered queries
  • Prefer UUID or ULID for distributed primary keys
  • Use transactions for multi-statement operations
  • Implement row-level security for multi-tenant apps

MongoDB

  • Design schemas around access patterns (embed vs reference)
  • Use compound indexes matching query patterns
  • Leverage aggregation pipeline for complex transformations
  • Use change streams for real-time data sync
  • Implement schema validation at the database level

Redis

  • Use appropriate data structures (strings, hashes, sorted sets, streams)
  • Set TTL on all cache entries
  • Use Redis transactions (MULTI/EXEC) for atomic operations
  • Implement pub/sub for real-time messaging
  • Use Redis Streams for reliable message queues

Migration Rules

  • Migrations must be reversible (up and down)
  • Never modify a deployed migration -- create a new one
  • Test migrations against production-like data volumes
  • Use zero-downtime migration patterns for live systems
  • Back up data before destructive migrations
Files

What ships with it

17 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

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.

databases is a skill published in the GitHub repository ihatesea69/kiro-kit (18 stars, last pushed 20d ago), licensed MIT. It adds 34 tokens to every session and 365 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 2026-09-03.
