toki: Instructions file for Codex

AGENTS.md

toki AGENTS.md is an instructions file for Codex, OpenCode from choi138/toki. It costs 1,581 tokens per session, scanned A, original, MIT.

A set of instructions for developing Toki, a Swift desktop application. It points agents to the project's source conventions, review process, and Git workflow before they edit code or resources.

In plain words
What is it for?
It helps with editing Toki's Swift source, tests, app resources, and XcodeGen configuration, then reviewing the local changes.
Why use it?
It reduces mistakes caused by ignoring project-specific rules and makes changes easier to review and keep consistent.

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

This is choi138/toki's own configuration. It tells Codex and OpenCode how to work on toki 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 toki 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

toki 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 1mo 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.

Workspace Rules

This file is the high-level policy entry point for AI tooling in this repository. Keep detailed source rules out of AGENTS.md; store them in the Codex conventions files referenced below.

Source Of Truth

Topic Source When
Toki Source Conventions /project-conventions skill or .agents/skills/project-conventions/conventions.md plus task-specific files under .agents/skills/project-conventions/references/ Before editing menubar/Toki/**/*.swift, menubar/TokiTests/**/*.swift, menubar/project.yml, .swiftformat, .swiftlint.yml, or app resources
Local Codex Review Loop /codex-review-loop skill or .agents/skills/codex-review-loop/SKILL.md Local diff review, approved finding fixes, and bounded re-review
Git Workflow .agents/conventions/git-workflow.md Branch / commit / PR work

The shared .agents hooks provide soft enforcement for /project-conventions at session start, on matching prompts, and on Bash commands that appear to modify Toki source, tests, resources, or XcodeGen configuration. This is a Codex-native reminder layer, not a hard block for non-shell edits.

Toki Workflow

Toki is a macOS menu bar app built with Swift, SwiftUI, XcodeGen, SwiftFormat, and SwiftLint.

  1. Inspect the existing local pattern before changing code.
  2. Keep app entry code in menubar/Toki/App, domain models and builders in menubar/Toki/Domain, platform and data readers in menubar/Toki/Infrastructure, feature UI/view-model code in menubar/Toki/Features, and tests in menubar/TokiTests.
  3. Prefer editing menubar/project.yml and regenerating with xcodegen generate from menubar/ for project configuration changes. Avoid hand-editing menubar/Toki.xcodeproj unless the user explicitly asks for a project-file-only fix or regeneration is not possible.
  4. Treat local agent logs, usage databases, security audit findings, and secret detection data as sensitive. Do not add telemetry, network transmission, or unmasked logging for those values unless explicitly requested.
  5. Keep SwiftUI views focused on presentation. Move parsing, aggregation, pricing, security scanning, persistence, and time calculations into domain, infrastructure, or view-model code.
  6. Add or update focused tests for reader behavior, usage aggregation, formatting, security audit behavior, settings, and view-model logic when those surfaces change.

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.
