crud-checklist

A checklist for generating a complete CRUD command package. CRUD means creating, reading, updating, and deleting records.

In plain words
What is it for?
Use it to plan commands that list, show, create, update, and delete a resource across the package's layers.
Why use it?
It reduces the risk of forgetting the domain types, API methods, adapters, mocks, demo data, or command files needed for a full feature.

Command for Claude Code

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.

Made for: Claude Code.

Per session 0 Only the description is in the session, so the agent can decide to use it. The body loads when it is invoked.
When invoked 640 The whole file, excluding the scripts and references it only reads on demand.
Security scan A 0 findings. Scan, not verified.
Origin original No closer match found in the catalogue.
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

crud-checklist 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 2d 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.

CRUD Command Generation Checklist

Complete checklist for generating a full CRUD command package.


Pre-Generation

  • Resource name (singular, e.g., "widget")
  • Parent command if nested (e.g., "email" for "email drafts")
  • Operations needed: list, show, create, update, delete
  • API endpoint path (e.g., "/grants/{grantID}/widgets")
  • Key fields from API spec

Files to Generate

Domain Layer

  • internal/domain/{resource}.go
    • Main type with JSON tags
    • CreateRequest type
    • UpdateRequest type
    • QueryParams type
    • Helper methods (DisplayName, etc.)

Port Layer

  • internal/ports/nylas.go - Add interface methods:
    • List{Resource}s
    • Get{Resource}
    • Create{Resource}
    • Update{Resource}
    • Delete{Resource}

Adapter Layer

  • internal/adapters/nylas/{resource}s.go - Implementation
  • internal/adapters/nylas/mock_{resource}.go - Mock functions
  • internal/adapters/nylas/demo_{resource}.go - Demo data

CLI Layer

  • internal/cli/{resource}/{resource}.go - Root command
  • internal/cli/{resource}/list.go - List subcommand
  • internal/cli/{resource}/show.go - Show subcommand
  • internal/cli/{resource}/create.go - Create subcommand
  • internal/cli/{resource}/update.go - Update subcommand
  • internal/cli/{resource}/delete.go - Delete subcommand
  • internal/cli/{resource}/helpers.go - Standard helpers
  • internal/cli/{resource}/{resource}_test.go - Unit tests

Registration

  • cmd/nylas/main.go - Add command import and registration

Verification

# Build
go build ./...

# Test
go test ./internal/cli/{resource}/... -v
go test ./... -short

# Verify command
./bin/nylas {resource} --help
./bin/nylas {resource} list --help

# Full CI
make ci-full

Common Flags per Subcommand

Subcommand Required Flags Optional Flags
list - --limit, --format
show --format
create resource-specific --format
update resource-specific
delete --force

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.

crud-checklist is a command published in the GitHub repository nylas/cli (68 stars, last pushed 14d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 640 tokens. 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.
