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.

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 | $0.00050 | $0.03138 |
| Opus 5 | $0.00025 | $0.01569 |
| Sonnet 5 | $0.00010 | $0.00628 |
| Haiku 4.5 | $0.00005 | $0.00314 |
Grade A, and why
manage-navigation 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 yesterday.
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.

Navigation Management Skill
This skill covers inspecting and modifying Mendix navigation profiles via MDL: home pages, menu items, login pages, role-based routing, and navigation catalog queries.
When to Use This Skill
Use when the user asks to:
- View or change navigation home pages
- View or modify the navigation menu structure
- Set login or not-found pages
- Configure role-based home page routing
- Discover which pages are navigation entry points
- Set up navigation for a new project
Navigation Concepts
-
Navigation Profiles — Every Mendix project has navigation profiles: Responsive, Phone, Tablet, and optionally Native. Each profile has its own home page, menu, and login page. The web kinds are a closed set and
create or replace navigationwill create one that does not exist yet:Online Offline twin ResponsiveResponsiveOfflinePhonePhoneOfflineTabletTabletOfflineAn invented name (
Mobile,Desktop) is an error, not a new profile: Mendix routes on User-Agent to its own kinds, so a profile the platform does not define can never be reached. Native profiles are a different document type and are not creatable from MDL. -
Offline Profiles — An offline profile makes the app work without a connection (a PWA with a local database that syncs). It is not a different document — same properties as its online twin — but it constrains every page it can reach, see below.
-
Home Page — The default page shown after login. Can be a PAGE or MICROFLOW.
-
Role-Based Home Pages — Override the default home page per user role (e.g., admins see a dashboard, users see a task list).
-
Menu Items — Hierarchical menu tree. Each item has a caption and optionally targets a PAGE or MICROFLOW. Sub-menus nest with
menu 'caption' (...). -
Menu Documents — A separate document type (
Menus$MenuDocument) holding a reusable menu that a menu widget points at, e.g. Atlas_Core'sPhone_Menu. Not the same thing as a profile's menu, though both are built from the same items, so the item syntax is identical. Managed withcreate/describe/drop menu— see below. -
Login Page — Custom login page (optional; Mendix provides a default).
-
Not-Found Page — Custom 404 page (optional).
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.

manage-navigation is a skill published in the GitHub repository mendixlabs/mxcli (115 stars, last pushed 2d ago), licensed Apache-2.0. It adds 50 tokens to every session and 3,138 once invoked, about $0.0003 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.
