AGENTS.md

WICompress AGENTS.md is an instructions file for Codex, OpenCode from Weixi779/WICompress. It costs 1,288 tokens per session, scanned A, original, Apache-2.0.

Repository instructions for WICompress, a Swift package that processes and compresses images using Apple's ImageIO framework. They describe its products, supported Apple platforms, folder layout, and build and test commands.

In plain words
What is it for?
Use it when developing WICompress or WIImageIO, organizing Swift sources, resolving dependencies, or running package tests.
Why use it?
They make the package's architecture and platform boundaries clear before you change code. They also show how to build and test the package consistently.

Written for Codex and OpenCode: the file is AGENTS.md. Also seen: mentions AGENTS.md.

This is Weixi779/WICompress's own configuration. It tells Codex and OpenCode how to work on WICompress itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything WICompress configures →

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

WICompress AGENTS.md 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 yesterday.

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.

Project

WICompress is a Swift 6.2 ImageIO-based image processing and compression package. It publishes the high-level WICompress product and the lower-level WIImageIO product. The core is UIKit/AppKit-free and supports iOS 14+, macOS 11+, Mac Catalyst 14+, tvOS 14+, watchOS 7+, and visionOS 1+.

Commands

swift build
swift test
swift package resolve

GitHub Actions runs macOS build/tests, iOS Simulator package tests, and build-only gates for the remaining supported Apple platforms.

Repository Layout

Use capitalized names for Swift/package roots (Sources, Tests, Example) and lowercase names for auxiliary directories (docs, scripts). The public umbrella keeps its branded Sources/WICompress path. Supporting source paths are grouped by product context and mapped to target names in Package.swift:

Sources/image/domain       -> WIImageDomain
Sources/image/io           -> WIImageIO
Sources/image/rendering    -> WIImageRendering
Sources/compress/domain    -> WICompressDomain
Sources/compress/execution -> WICompressExecution
Sources/WICompress         -> WICompress

Nested organizational directories are lowercase. Target names are the module identity; physical paths do not repeat the WI brand.

Architecture Boundaries

flowchart TD
    Compress["WICompress"] --> ImageDomain["WIImageDomain"]
    Compress --> CompressDomain["WICompressDomain"]
    Compress --> Execution["WICompressExecution"]

    Execution --> ImageDomain
    Execution --> CompressDomain
    Execution --> ImageIO["WIImageIO"]
    Execution --> Rendering["WIImageRendering"]

    CompressDomain --> ImageDomain
    ImageIO --> ImageDomain
    Rendering --> ImageDomain

Arrows mean imports.

  • WIImageDomain owns shared image vocabulary and no execution lifecycle.
  • WIImageIO owns synchronous inspection, decode, transcode, and encode. It re-exports canonical Image Domain values instead of defining aliases.
  • WIImageRendering owns package-only single-image bitmap rendering until a public Rendering API is explicitly designed.
  • WICompressDomain owns public Process, Target, Output, Result, and compression error contracts.
  • WICompressExecution owns the request-scoped ImagePipeline, calculations, and lower-level error mapping. It publishes no product models.
  • WICompress is the public umbrella and terminal surface.

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.
