What is sct AGENTS.md?

Project guidance for SCT, a native macOS app for configuring the Squirrel input method. It describes how the app reads base YAML settings and writes user changes as separate custom YAML patches.

Understanding the two-layer configuration model, merged settings views, SwiftUI and Swift requirements, and YAML handling.

It helps agents preserve the input method's original settings while making user changes visible and reversible.

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	$0.03068	$0.03068
Opus 5	$0.01534	$0.01534

Security

Grade A, and why

sct 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.

Squirrel Configuration Tool (SCT) - Agent Guide

This document serves as a project overview and design record for AI agents working on the Squirrel (鼠须管) configuration GUI.

Project Overview

The goal is to provide a native macOS GUI for configuring the Squirrel input method, which traditionally requires manual editing of YAML files in ~/Library/Rime.

Core Design Philosophy

"Respect Rime Logic, Simplify User Operation"

Non-Destructive: Never modify default .yaml files. All changes must be written to .custom.yaml files under the patch: key.
Native Experience: Use SwiftUI and macOS design patterns to make configuration feel like a first-class system setting.
Transparency: Users should be able to see what YAML changes are being made.

Key Design Decisions

1. Dual-Layer Configuration Model

Base Layer: default.yaml, squirrel.yaml (Read-only).
Patch Layer: default.custom.yaml, squirrel.custom.yaml (Read/Write).
Merged View: The GUI displays the result of merging the Patch Layer into the Base Layer.

2. Technology Stack

Language: Swift 6.0+
Framework: SwiftUI (Targeting latest macOS)
YAML Engine: Yams for robust YAML parsing and serialization.
Markdown Engine: MarkdownUI for rich help documentation rendering.

3. Configuration Merging Logic

Rime's patch system supports:

Simple key-value replacement.
Nested key access (e.g., style/font_face).
Array manipulation (though SCT currently focuses on full array replacement for simplicity).

4. Color Handling

Rime uses BGR (Blue-Green-Red) hex format (e.g., 0xBBGGRR). SCT must:

Convert BGR to SwiftUI.Color for the UI.
Convert SwiftUI.Color back to BGR for saving.

Functional Modules

General Settings

menu/page_size: Number of candidates.
schema_list: Selection and ordering of input schemas.
ascii_composer: Behavior of Shift/Caps Lock keys.

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.
