A command reference for building, testing, formatting, linting, documenting, and benchmarking the skia-rs Rust workspace, with rules for Git use and commit messages.

Use it to check or build all crates, run tests and benchmarks, generate Rust documentation, format and lint code, and prepare Conventional Commits.

It keeps common development commands and repository conventions in one place, reducing missed checks and inconsistent commits.

commands — Cursor rule for Cursor by quinnjr

Install

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.

Clone the repo

git clone --depth 1 https://github.com/quinnjr/skia-rs

Made for: Cursor.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00303	$0.00303
Opus 5	$0.00151	$0.00151
Sonnet 5	$0.00061	$0.00061
Haiku 4.5	$0.00030	$0.00030

Measured 5d ago against content hash 3ff0edaf0e3a, method: parsed. Prices are Anthropic first-party input rates as of 2026-09-06, from the pricing page.

Security

Grade A, and why

commands 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.

Git Workflow

Keep the skia/ submodule updated for reference
Commit messages should reference Skia types/functions being implemented
Use feature branches for new implementations
Update TODO.md as features are completed

Conventional Commits

Commit messages must follow Conventional Commits:

feat(core): add Matrix inversion
fix(path): correct cubic curve bounds calculation
docs: update API documentation
refactor(canvas): simplify save/restore stack
test(paint): add property tests for color conversion

Pre-commit Hooks

The project uses cargo-husky for git hooks:

pre-commit: Runs cargo fmt --check and cargo clippy
pre-push: Runs full test suite
commit-msg: Validates Conventional Commits format

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.
