Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00097 | $0.02092 |
| Opus 5.5 | $0.00039 | $0.00837 |
| Sonnet 5.5 | $0.00019 | $0.00418 |
| Haiku 4.5 | $0.00010 | $0.00209 |
Grade A, and why
mvc-generator 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 1mo 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.

Protheus MVC Generator
Overview
Generate complete Protheus MVC screen implementations following the TOTVS framework patterns. Protheus MVC separates business rules (Model), visual presentation (View), and navigation/actions (Controller/Browse) using the FWFormModel, FWFormView, and FWFormBrowse framework classes. This skill generates the three mandatory functions (ModelDef, ViewDef, MenuDef) plus the Browse function that composes them.
When to Use
Use this skill when:
- Creating a new CRUD screen for a Protheus table
- Building a master-detail form (e.g., invoice header + items)
- Generating MVC boilerplate from a table alias
- Adding validations, triggers, and entry point hooks to MVC screens
- Migrating legacy AxCadastro/Mbrowse screens to MVC
MVC Architecture in Protheus
Core Components
┌─────────────────────────────────────────┐
│ Main Function (e.g., MYMOD01) │
│ ├── MenuDef() → Menu actions │
│ └── FWFormBrowse → Browse grid │
│ ├── ModelDef() → Business rules │
│ │ ├── FWFormStruct → Schema │
│ │ ├── FWFormFieldsModel (Form) │
│ │ ├── FWFormGridModel (Grid) │
│ │ └── Validations / Triggers │
│ └── ViewDef() → Visual layout │
│ ├── FWFormStruct → Schema │
│ ├── Form panels │
│ └── Grid panels │
└─────────────────────────────────────────┘
User Function Responsibilities
| Function | Purpose | Returns |
|---|---|---|
ModelDef() |
Defines the data model: fields, validations, relationships, triggers | FWFormModel object |
ViewDef() |
Defines the visual layout: panels, grids, field arrangement | FWFormView object |
MenuDef() |
Defines available actions: Include, Edit, Delete, View, Copy | Array of menu items |
| Main Function | Creates FWFormBrowse and activates the screen |

What ships with it
2 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.
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.

mvc-generator is a skill published in the GitHub repository totvs/engpro-advpl-tlpp-skills (164 stars, last pushed 8d ago), licensed MIT. It adds 97 tokens to every session and 2,092 once invoked, about $0.0004 per session on Opus 5.5. 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 2026-08-30.
