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.

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00112 | $0.02788 |
| Opus 5 | $0.00056 | $0.01394 |
| Sonnet 5 | $0.00022 | $0.00558 |
| Haiku 4.5 | $0.00011 | $0.00279 |
Grade A, and why
design-to-react-algorithms 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 5d 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.

dot-skills Design-to-React Conversion Best Practices
The reverse-engineering pipeline that converts Sketch files into pixel-perfect React + CSS, with regression-safe iteration as the load-bearing constraint. The skill is organized around the cascade effect of design-to-code conversion: a wrong call in stage N corrupts every output from stage N+1 onward, so categories are ordered by how much downstream they own.
The user's primary requirement — "each improvement doesn't cause regressions" — is enforceable only if the iteration loop, the layer tree, and the layout solver are correct before you start polishing styles. Read the rules in priority order.
When to Apply
- Building a converter that ingests a
.sketchfile (or equivalent design source) and emits React + CSS - Iterating on an existing converter where each improvement risks breaking other components
- Diagnosing why a converted component "almost matches" the design but visual-regression fails
- Designing the snapshot-gate / baseline strategy for a design-to-code pipeline
- Choosing between flexbox vs grid vs absolute positioning when the source is freeform geometry
- Translating Sketch-specific primitives (
MSImmutableFlexGroupLayout,attributedString,curvePoint,MSImmutableStyleCorners) into idiomatic CSS
Rule Categories by Priority
The ordering is the cascade — fix earlier stages first; later-stage fixes are wasted if the upstream tree is wrong.
| Priority | Category | Impact | Prefix |
|---|---|---|---|
| 1 | Reverse-Engineering Iteration Strategy | CRITICAL | iter- |
| 2 | Tree Reconstruction & Symbol Resolution | CRITICAL | tree- |
| 3 | Layout Algorithms (Flex/Freeform Inference) | CRITICAL | layout- |
| 4 | Coordinate & Geometry Math | HIGH | geom- |
| 5 | Visual Regression & Diff Algorithms | HIGH | diff- |
| 6 | Style Translation (Color, Gradient, Shadow, Border) | MEDIUM-HIGH | style- |
| 7 | Typography Math | MEDIUM | type- |
| 8 | Path & Shape Rendering | MEDIUM | path- |

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.

design-to-react-algorithms is a skill published in the GitHub repository pproenca/dot-skills (205 stars, last pushed 24d ago), licensed MIT. It adds 112 tokens to every session and 2,788 once invoked, about $0.0006 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 2026-09-03.
