Use Compose service names for container commands.

docker-compose.development.yml defines api without container_name. Compose derives the container name from the project name, service name, and index. .env.example and README.md use project names such as amber_<env> and amber_development, so development-environment-alpha-1 is not guaranteed. Use docker-compose -f docker-compose.development.yml exec api ... and docker-compose -f docker-compose.development.yml logs api instead.

Use /app in the direct-entry instruction.

The service-based command can avoid the path change, but AGENTS.md:8 still instructs users to run cd ~/amber-api. The Dockerfile creates and uses /app and does not create ~/amber-api, so this command can fail before bundle exec runs.

Change it to cd /app.

## Rules
1. Follow existing patterns
2. Tests for everything (95%+ coverage)
3. Follow RuboCop or document exception with reason
4. Keep it simple: convention over configuration
5. Don't add gems unless they have real benefit (student-maintained, avoid bloat)

## RuboCop
Config: `.rubocop.yml`
Target: Rails 7.2, Ruby 3.3, NewCops: enable
Disabled: HttpPositionalArguments, HasManyOrHasOneDependent, InverseOf, LexicallyScopedActionFilter, RSpec/LeadingSubject, Documentation, FrozenStringLiteralComment, GuardClause
Modified: RSpec/NestedGroups Max:5, Style/ClassAndModuleChildren excludes v1 resources, Metrics/BlockLength excludes spec/**
Exceptions: Must explain why in .rubocop.yml comments

## Structure
Resources: `app/resources/v1/*.rb` extends `V1::ApplicationResource < JSONAPI::Resource`
Tests: `spec/resources/v1/*_spec.rb` type: :resource
Factories: `spec/factories/*.rb` use FactoryBot + Faker

## Resource Template
```ruby
# app/resources/v1/model_resource.rb
class V1::ModelResource < V1::ApplicationResource
attributes :attr1, :attr2
has_one :user
has_many :items
filter :field

def self.creatable_fields(context)
%i[attr1 attr2]
end

Align the resource template with the enabled RuboCop rule.

When copied into app/resources/v1/*.rb, creatable_fields(context) triggers enabled Lint/UnusedMethodArgument. .rubocop.yml does not disable this cop. Update the template and the related guidance to use _context, consistent with existing resources.

def self.updatable_fields(context)
creatable_fields(context)
end

def self.searchable_fields
%i[attr1 attr2]
end
end
```

## Test Template
```ruby
# spec/resources/v1/model_resource_spec.rb
require 'rails_helper'

RSpec.describe V1::ModelResource, type: :resource do
let(:user) { create(:user) }
let(:context) { { user: } }

describe '#creatable_fields' do
it { expect(described_class.creatable_fields(context)).to match_array(%i[attr1 attr2]) }
end

describe '#updatable_fields' do
it { expect(described_class.updatable_fields(context)).to match_array(%i[attr1 attr2]) }
end
end
```

## Factory Template
```ruby
# spec/factories/models.rb
FactoryBot.define do
factory :model do
user
attr1 { Faker::Lorem.word }
attr2 { [true, false].sample }
end
end
```

## Test What
Resources: creatable_fields, updatable_fields, fetchable_fields, searchable_fields, filters, relationships, attributes, permissions
Models: validations, associations, scopes, methods, callbacks
Controllers: auth, Pundit policies, response codes, response body, error handling

## Commands
Test all: `bundle exec rspec`
Test file: `bundle exec rspec spec/path/to/file_spec.rb`
Test line: `bundle exec rspec spec/path/to/file_spec.rb:12`
RuboCop: `bundle exec rubocop`
RuboCop fix: `bundle exec rubocop -a`
Guard: `bundle exec guard`
DB: `bundle exec rails db:migrate`, `bundle exec rails g migration Name`

## Docker Commands
Enter: `docker exec -it development-environment-alpha-1 /bin/bash -l` then `cd ~/amber-api`
Start: `cd "C:/Users/jorai/Programeren/1. Alpha/1. Development/amber-api" && docker-compose -f docker-compose.development.yml up -d api`

Remove the developer-specific host path.

The start command only works for C:/Users/jorai/.... Other contributors cannot run it from their checkout. Document the command from the repository root instead.

Proposed fix
-Start: `cd "C:/Users/jorai/Programeren/1. Alpha/1. Development/amber-api" && docker-compose -f docker-compose.development.yml up -d api`
+Start: From the repository root, run `docker-compose -f docker-compose.development.yml up -d api`
📝 Committable suggestion

‼️ IMPORTANT
Carefully review the code before committing. Ensure that it accurately replaces the highlighted code, contains no missing lines, and has no issues with indentation. Thoroughly test & benchmark the code to ensure it meets the requirements.

Suggested change
Start: `cd "C:/Users/jorai/Programeren/1. Alpha/1. Development/amber-api" && docker-compose -f docker-compose.development.yml up -d api`
Start: From the repository root, run `docker-compose -f docker-compose.development.yml up -d api`

In `@AGENTS.md` at line 99, Update the Start command in AGENTS.md to remove the
developer-specific absolute host path and document the docker-compose command
runnable from the repository root, preserving the existing development compose
file and api service options.

After applying the fix, consider running `coderabbit review --agent` for local
review. Visit https://docs.coderabbit.ai/cli?utm_source=ghpr.

Stop: `docker-compose -f docker-compose.development.yml down`
Logs: `docker logs development-environment-alpha-1`

## Pitfalls
- Don't use `docker exec ... bundle exec ...` directly (PATH + working dir issues)
- Don't skip tests
- Don't ignore RuboCop
- Don't use hash rockets `{:key => val}` except in excluded dirs
- Don't over-engineer
- Don't use `_context` param if unused (keep it for consistency)
- Do use existing patterns from ApplicationResource for permissions
