Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

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 5.1 | $0.00233 | $0.05795 |
| Opus 5.5 | $0.00093 | $0.02318 |
| Sonnet 5.5 | $0.00047 | $0.01159 |
| Haiku 4.5 | $0.00023 | $0.00579 |
Grade A, and why
build-quick-design-calculator 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 24d 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 — 366 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Build a Quick Design Calculator
SkyCiv Quick Design turns a small bundle of files — a calc pack — into a hosted calculation
tool. SkyCiv generates the UI from your config.json, runs calculate.js on its servers, and
handles reporting, units, PDF export, batch runs and (optionally) Structural 3D integration.
Prerequisite / boundary: this skill is for authoring a calculator. The pack is uploaded as a folder at platform.skyciv.com/quick-design?uid=build (Build Your Own Calculator → Upload Code). No API key, session or
{ auth, options, functions }envelope is involved —skyciv-api-v3does not apply. To call an already-published calculator by UID over REST, userun-quick-design.
Calc pack layout
| Path | Purpose |
|---|---|
config.json |
Required. Metadata + every input variable; the UI form is generated from it. A minimal pack is just this plus calculate.js. |
calculate.js |
Required. Server-side logic: takes the input JSON, writes the report, returns { report, results }. |
ui.js |
Client-side; draws into the canvas/div elements declared in the config. |
docs.md |
Documentation tab — overview, assumptions, changelog. |
s3d_integration.js |
Puts the calculator in Structural 3D, batch-running over model members. |
renderer.js |
Adds a SkyCiv 3D Renderer panel. |
utils/*.js |
Shared modules via requireUtil('name.js'). Must use module.exports. |
json/*.json, csv/*.csv |
Lookup data via requireJSON() / requireCSV(). |
images/* |
Served from the pack; reference as /name.png. |
metric/ or imperial/ |
Manual dual-unit packs only — see Units. |
test_files/Test N/ |
Builder regression tests: input.json + expected_return.json. |
unit_tests/**/*.test.js |
Local Jest tests over utils/; not uploaded. |

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.

build-quick-design-calculator is a skill published in the GitHub repository skyciv/skyciv-ai-skills (11 stars, last pushed 15d ago), licensed MIT. It adds 233 tokens to every session and 5,795 once invoked, about $0.0009 per session on Opus 5.5. 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 2026-09-22.
