external-scale

external-scale is a cursor rule for Cursor from Ocean-Industries-Concept-Lab/openbridge-webcomponents. It costs 0 tokens per session (4,449 once invoked), scanned A, original, Apache-2.0.

Development rules for shared scale-based components such as bars and gauges. These components display values against an outside scale and share related settings across vertical, horizontal, and trend versions.

In plain words
What is it for?
Use them when changing the external scale renderer or any bar and gauge wrapper, especially when adding properties or configuration that must be passed through related components.
Why use it?
A change to one component can affect several connected components. The rules help keep their APIs and behavior aligned instead of letting similar variants drift apart.

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

external-scale 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 4d 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.

External Scale & Bar/Gauge Components

These instructions apply to the external scale renderer and its thin wrapper components (bar-vertical, bar-horizontal, gauge-vertical, gauge-horizontal, gauge-trend).

⚠️ IMPORTANT: Interconnected Components

All components in this system are tightly interconnected and share a common API surface:

  • external-scale.tsbar-vertical.tsbar-horizontal.tsgauge-vertical.tsgauge-horizontal.tsgauge-trend.ts

When implementing a new feature or changing existing behavior:

  1. Changes must cascade through ALL related components to maintain consistency
  2. All wrappers expose similar properties with orientation-specific naming (e.g., height/width, paddingTop/paddingLeft)
  3. If you add a property to bar-vertical, you likely need to add the equivalent to bar-horizontal, gauge-vertical, gauge-horizontal, gauge-trend and external-scale
  4. If you add a config option to external-scale.ts, all wrappers need to expose and pass it
  5. Gauge variants (gauge-vertical/gauge-horizontal/gauge-trend) may intentionally NOT expose certain properties (they use fixed values)

Before completing any change, verify:

  • external-scale.ts has the core logic/config
  • bar-vertical.ts exposes and maps the property correctly
  • bar-horizontal.ts has the mirrored equivalent
  • gauge-vertical.ts / gauge-horizontal.ts / gauge-trend.ts are updated if applicable
  • All components remain API-consistent

Architecture Overview

The external scale system follows a renderer + wrapper pattern:

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.

external-scale is a cursor rule published in the GitHub repository Ocean-Industries-Concept-Lab/openbridge-webcomponents (91 stars, last pushed today), licensed Apache-2.0. It costs nothing until one of its globs matches a file; then it loads 4,449 tokens. 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.
