creating-mongoose-schemas is a skill for Claude Code from narpatsinghpurohit/tstack. It costs 66 tokens per session (439 once invoked), scanned A, original, MIT.

A guide for adding a MongoDB data model to a NestJS backend using Mongoose, a library for working with MongoDB. It covers the model definition, database indexes, automatic fields, and its repository for database access.

In plain words
What is it for?
Use it when adding a MongoDB collection or defining an entity such as a product, course, or user-owned record in the API.
Why use it?
It gives new collections a consistent structure and keeps database access aligned with the project's conventions. It also helps avoid missed registration, indexing, or data-protection details.

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

creating-mongoose-schemas 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 9d 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

Live Context

  • Existing schemas: !find apps/api/src/modules -name "*.schema.ts" -not -path "*/node_modules/*" 2>/dev/null

Task

Create Mongoose schema for: $ARGUMENTS


Creating Mongoose Schemas

Workflow

- [ ] Step 1: Define the schema class with decorators
- [ ] Step 2: Add indexes for query performance
- [ ] Step 3: Add virtuals and hooks (if needed)
- [ ] Step 4: Create repository extending BaseRepository
- [ ] Step 5: Register in feature module

Schema design guidelines

  • Always include orgId as the first field — BaseRepository requires it
  • Always enable timestamps: true for createdAt and updatedAt
  • Use select: false for sensitive fields like passwordHash
  • Use trim: true on string fields
  • Use lowercase: true on email fields
  • Use enum for fields with known set of values
  • Prefer .lean() in repository reads for performance

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.
