SimpleORM entity-to-database mapping via RTTI attributes. An agent skill from academiadocodigo/SimpleORM.
- Databases work in your project
- SKILL.md covers Entity Template, All Available Attributes…, Supported Property Types and Relationship Setup Examples, plus 1 more section
- Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md
What it does
Entity Mapping is an agent skill from academiadocodigo/SimpleORM. SimpleORM entity-to-database mapping via RTTI attributes. Complete reference for all attributes, property types, and relationship setup.
Its SKILL.md is about 820 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It sits in Databases. The repository describes itself as: ORM Simples para Aplicações Delphi. The licence is MIT.
When your agent uses it
- Databases work in your project
Example prompts
- “/entity-mapping”
What it can do on your machine
Read from SKILL.md and the folder at commit 6227399. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md (its code samples are pascal).
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Entity Mapping loads about 816 tokens when it runs. Until then it costs about 38 tokens; SKILL.md has 183 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Table & Column
| Attribute | Target | Purpose |
|---|---|---|
Tabela('NAME') | class | Maps to database table |
Campo('NAME') | property | Maps to column name |
Keys
| Attribute | Purpose |
|---|---|
PK | Primary key (exactly one) |
FK | Foreign key |
AutoInc | Auto-increment (excluded from INSERT) |
Constraints & Validation
| Attribute | Purpose |
|---|---|
NotNull | Required field |
NotZero | Numeric cannot be zero |
Ignore | Skip in all SQL operations |
Email | Validates email format |
MinValue(n) | Minimum numeric value |
MaxValue(n) | Maximum numeric value |
Regex('pattern', 'msg') | Custom regex validation |
Format(maxSize, precision) | Size/precision constraints |
Display & Binding
| Attribute | Purpose |
|---|---|
Display('Label') | Display name for grids/forms |
Bind('FIELD') | Binds form component |
NumberOnly | Numeric-only input |
Relationships
| Attribute | Cardinality | Loading |
|---|---|---|
HasOne('Entity', 'FK') | 1:1 | Eager |
BelongsTo('Entity', 'FK') | N:1 | Eager |
HasMany('Entity', 'FK') | 1:N | Lazy (TSimpleLazyLoader) |
BelongsToMany('Entity', 'FK') | M:N | Manual |
Special
| Attribute | Purpose |
|---|---|
SoftDelete('FIELD') | On class — logical deletion |
Enumerator('TYPE') | PostgreSQL enum cast |
Supported Property Types
| Delphi Type | JSON Serialization | DB Param Type |
|---|---|---|
String | string | ftString |
Integer | number | ftInteger |
Int64 | number | ftLargeint |
Double | number | ftFloat |
TDateTime | ISO8601 string | ftDateTime |
Boolean | true/false | ftBoolean |
Relationship Setup Examples
HasOne/BelongsTo — eager loaded by DAO:
[HasOne('PEDIDO', 'ID_PEDIDO')]
property Pedido: TPedido read FPedido write SetPedido;HasMany — lazy loaded:
uses SimpleProxy;
FItens := TSimpleLazyLoader<TItemPedido>.Create(Query, 'ID_PEDIDO', Self.Id);RTTI Flow
Entity class → TSimpleRTTI<T> extracts:
.TableName → reads [Tabela] attribute
.Fields → iterates published properties with [Campo]
.PrimaryKey → finds property with [PK]
.Where → builds PK = :PK condition
.FieldsInsert → Fields minus [AutoInc]
.SoftDeleteField → reads [SoftDelete] from class© academiadocodigo, MIT. Rendered from Markdown: HTML in the file is shown as text, images as links, and headings moved down two levels. Raw file
