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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.04449 |
| Opus 5 | $0.00000 | $0.02225 |
| Sonnet 5 | $0.00000 | $0.00890 |
| Haiku 4.5 | $0.00000 | $0.00445 |
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.
How it starts
The opening of the file, as written. The whole thing — 363 lines — stays where its author put it; the contents beside it link to each section on GitHub.
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.ts↔bar-vertical.ts↔bar-horizontal.ts↔gauge-vertical.ts↔gauge-horizontal.ts↔gauge-trend.tsWhen implementing a new feature or changing existing behavior:
- Changes must cascade through ALL related components to maintain consistency
- All wrappers expose similar properties with orientation-specific naming (e.g.,
height/width,paddingTop/paddingLeft)- If you add a property to
bar-vertical, you likely need to add the equivalent tobar-horizontal,gauge-vertical,gauge-horizontal,gauge-trendandexternal-scale- If you add a config option to
external-scale.ts, all wrappers need to expose and pass it- 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.tshas the core logic/configbar-vertical.tsexposes and maps the property correctlybar-horizontal.tshas the mirrored equivalentgauge-vertical.ts/gauge-horizontal.ts/gauge-trend.tsare updated if applicable- All components remain API-consistent

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.

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.
