Modules And Routing

A guide to placing application modules, making pages reachable by URL, and connecting features to the logged-in application shell.

In plain words
What is it for?
Use it to create routed pages, settings screens, tools, workflows, reusable modules, or persisted widget canvases.
Why use it?
It helps agents choose between a full feature page and a user-configurable widget board, while keeping implementations in the correct module locations.

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.

Token cost

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.

Security

Grade A, and why

Modules And Routing 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 2d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (panel-tools.js), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 122 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Use this skill when creating or updating routed modules, deciding where files belong, or wiring a feature into the authenticated app shell.

If the user wants a reusable app surface, tool UI, settings panel, or workflow screen, prefer a custom routed page module over a space. Spaces are for persisted user-authored widget canvases; custom pages are for feature-owned interfaces.

First-Party Module Placement

  • Browser modules are namespaced as mod/<author>/<repo>/....
  • Repo-owned first-party modules should normally live under app/L0/_all/mod/_core/<feature>/.
  • A routed feature should usually own its own view.html under that module root.
  • Keep the module root as the real implementation location and use ext/html/... files only as thin adapters into existing seams.

Custom Pages Instead Of Spaces

  • Build a custom routed page when the extension should behave like a first-class feature screen instead of a widget on a persisted space canvas.
  • Use spaces when the user wants a configurable board of widgets that lives under ~/spaces/....
  • Use a routed page when the feature owns its own layout, state, and navigation flow.
  • To make a custom page appear in the dashboard Panels section, add ext/panels/<name>.yaml in the owning module.
  • Panel manifests should define name, path, optional description, optional icon, and optional color.
  • For first-party _core routes, the manifest path may use shorthand such as user instead of a full /mod/... path.
  • Panel manifest path values may use shorthand route paths such as user, prefixed hash paths such as #/user, or direct /mod/... HTML paths such as /mod/_core/user/view.html.

Router Resolution

  • The main app is hash-routed.
  • #/dashboard resolves to /mod/_core/dashboard/view.html.
  • #/time_travel resolves to /mod/_core/time_travel/view.html.
  • A multi-segment route such as #/author/repo/path resolves to /mod/author/repo/path/view.html.
  • If the final route segment already ends in .html, the router resolves directly to that file under /mod/....
  • Query parameters stay attached to the resolved route target.

What ships with it

1 file 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.

Changes

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.

Modules And Routing is a skill published in the GitHub repository binary16labs/prime-silo (5 stars, last pushed 9d ago), licensed MIT. It adds 28 tokens to every session and 1,188 once invoked, about $0.0001 per session on Opus 5. A static security scan graded it A with 0 findings. It is 100% identical to Modules And Routing, differing in 6 lines, and is treated as a copy.
