screenize AGENTS.md

Project instructions for screenize, a macOS screen-recording and editing app built with SwiftUI. They describe the required agent workflow and the commands used to build, check, and test the app.

In plain words
What is it for?
Use them when changing screenize source code, running its Xcode build, checking lint, or running tests. They tell the agent to find prior context first and record the finished work afterward.
Why use it?
They make repository work more consistent and ensure related work is checked before changes begin. They also require logging completed work and provide the exact verification commands.

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.

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

screenize 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 2d 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.

AGENTS.md

Guidance for autonomous coding agents working in this repository.

Repository Snapshot

  • Project: Screenize (macOS screen recording and editing app)
  • Language: Swift
  • UI framework: SwiftUI
  • Target platform: macOS 13+
  • Build system: Xcode project (Screenize.xcodeproj)
  • External dependency: Sparkle (via Swift Package Manager)

Mandatory Agent Workflow

Follow this sequence for each meaningful work unit:

  1. START: run the work-context-finder agent to check prior related work.
  2. WORK: implement the task.
  3. FINISH: execute /log-work using the work-logger skill.

Notes:

  • This workflow is defined in CLAUDE.md and should be treated as repository policy.
  • All generated logs/summaries/tags for vector DB workflows must be in English.

Build, Lint, and Test Commands

Run all commands from repository root (/Users/sung-yein/Workspace/screenize).

Build

xcodebuild -project Screenize.xcodeproj -scheme Screenize -configuration Debug build

Lint

./scripts/lint.sh

Auto-fix lint violations where possible:

./scripts/lint.sh --fix

Tests (Current Status + How To Run)

Current repository status:

  • There is currently no test target configured in Screenize.xcodeproj.
  • There are currently no *Tests* files/directories in the repo.
  • Primary verification today is successful build + lint.

When tests are added, use these command patterns:

Run all tests for a scheme:

xcodebuild -project Screenize.xcodeproj -scheme Screenize -destination 'platform=macOS' test

Run a single test class:

xcodebuild -project Screenize.xcodeproj -scheme Screenize -destination 'platform=macOS' -only-testing:ScreenizeTests/MyFeatureTests test

Run a single test method:

xcodebuild -project Screenize.xcodeproj -scheme Screenize -destination 'platform=macOS' -only-testing:ScreenizeTests/MyFeatureTests/testExample test

Tip: if scheme/target names differ, inspect with:

xcodebuild -list -project Screenize.xcodeproj

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.
