What it does
Yuedu Tour is an agent skill from CHANG-JUI-LIN/Yuedu-reader. Locate Yuedu module ownership and cross-module data flows when the relevant entry points or boundaries are unclear.
Its SKILL.md is about 500 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files (for example `references/coretext.md`, `references/library-services.md` and `references/localization.md`).
It sits in Mobile, covering iOS development. It works with iOS and SwiftUI. The repository describes itself as: Yuedu is a native iOS reader that supports multiple book formats, RSS subscriptions, and user-provided book sources. The licence is MPL-2.0.
When your agent uses it
- Tasks that involve iOS development
Example prompts
- “/yuedu-tour”
What it can do on your machine
Read from SKILL.md and the folder at commit b24d525. It shows what the files ask for, not the result of running them.
Tool permissions
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Yuedu Tour loads about 497 tokens when it runs, and up to ~11k if it reads all its reference files. Until then it costs about 32 tokens; SKILL.md has 224 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
Safety
Auto-check passed
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

- yuedu-tour
- description
- Locate Yuedu module ownership and cross-module data flows when the relevant entry points or boundaries are unclear.
Yuedu Code Tour
Use this map when code ownership or a cross-module path is unclear. A known local edit does not require a tour. Search the relevant symbol first and read only the matching reference section.
Swift sources live in Modules/ and Targets/; resources in Resources/; regression tests in Tests/iOS/yuedu appTests/. File-system-synchronized Xcode groups include new Swift files automatically.
References by Task
- Module map: find entry points, service owners, and extension points.
- CoreText: rendering, CSS, pagination, scrolling, and position invariants. Search for the affected property or engine; do not load all pitfalls by default.
- Online reading: book sources, rule extraction, and chapter flow.
- Library services: bookshelf persistence, account sign-in, or RSS; read the matching section.
- Localization: adding or changing user-facing strings.
- Workflows: guidance when the relevant implementation path remains unclear.
Follow repository AGENTS.md for regression testing, title modes, localization, and the single online-session path. Use CLAUDE.md's Build & Test section when actually running Xcode; resolve the toolchain and simulator with scripts/sim.sh, never a hardcoded device name. Known historical failures are diagnostic clues, not proof that a current failure is unrelated.
Maintenance
This repository-local skill and its references are the canonical code tour. Global aliases and the Claude entry point link here; update this source rather than maintaining duplicated copies. Preserve task-specific evidence in the appropriate reference, not in the description or a mandatory all-task checklist.
