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 | $0.00024 | $0.00424 |
| Opus 5 | $0.00012 | $0.00212 |
| Sonnet 5 | $0.00005 | $0.00085 |
| Haiku 4.5 | $0.00002 | $0.00042 |
Grade A, and why
GeneXus 18 Guidelines 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 11d 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
GeneXus 18 Development Guidelines
Use this skill to ensure high-quality, performant, and secure GeneXus 18 development. It coordinates specialized references for different object types and logic patterns.
Triggers
- Mentions of GeneXus object types (Transaction, Procedure, Data Provider, etc.)
- Knowledge Base modeling tasks
- Requests for generating or reviewing GeneXus code
- Data modeling and normalization questions
Responsibilities
- Provide deep, object-specific guidance based on modular references.
- Ensure consistency between Data Modeling and Logic Implementation.
- Apply GeneXus 18 best practices for performance and security.
- Coordinate multiple objects in complex development tasks.
Structure
This skill uses a modular reference architecture:
references/global-guidelines.md: Core engineering rules and security.references/object-*.md: Specialized knowledge for each object type (e.g., Transaction, Procedure).references/common-*.md: Shared logic patterns (e.g., Commands, Rules, Events).
Resource Selection Protocol
- Load
references/global-guidelines.mdfor overall architecture. - Load the corresponding
references/object-*.mdbased on the objects being discussed. - Load
references/common-*.mdfor specific logic or syntax questions.
Reference List
What ships with it
6 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.

GeneXus 18 Guidelines is a skill published in the GitHub repository lennix1337/Genexus18MCP (30 stars, last pushed today), licensed MIT. It adds 24 tokens to every session and 424 once invoked, about $0.0001 per session on Opus 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.
