What it does
Code Nav is an agent skill from ncatbot/NcatBot. 定位 NcatBot 代码实现：锁定模块目录、找到关键类/函数、追踪调用链。当文档不够时才读代码，用搜索而非遍历。Use when: 找代码实现、哪个文件、哪个类、追踪调用链、定位 bug 行号、代码在哪、模块目录、源码定位。
Its SKILL.md is about 460 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/event-chains.md` and `references/module-code-map.md`).
The repository describes itself as: NapCat Python SDK；快速开发你的 QQ 机器人.

What it can do on your machine
Read from SKILL.md and the folder at commit c26300a. 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
Code Nav loads about 460 tokens when it runs, and up to ~2.9k if it reads all its reference files. Until then it costs about 31 tokens; SKILL.md has 100 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.
SKILL.md
Its licence (Custom licence) doesn't allow us to republish the file, so here is its outline and opening line. It has 100 words (~460 tokens).
- name
- code-nav
Files
SKILL.md and 2 other files (references) in .agents/skills/code-nav of ncatbot/NcatBot.
- SKILL.md
- references/event-chains.md
- references/module-code-map.md

When should I use Code Nav?
Code Nav fits situations like: : 找代码实现、哪个文件、哪个类、追踪调用链、定位 bug 行号、代码在哪、模块目录、源码定位.
How do I install Code Nav in Claude Code?
Run `npx skills add ncatbot/NcatBot --skill code-nav -a claude-code`. Or copy the skill folder (.agents/skills/code-nav in ncatbot/NcatBot) into .claude/skills/code-nav in your project. Claude Code loads it when a task matches its description.
How do I install Code Nav in Codex?
Run `npx skills add ncatbot/NcatBot --skill code-nav -a codex`. Or copy the skill folder (.agents/skills/code-nav in ncatbot/NcatBot) into .agents/skills/code-nav in your project. Codex loads it when a task matches its description.
Can I use Code Nav in Cursor, Gemini CLI or GitHub Copilot?
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add ncatbot/NcatBot --skill code-nav -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/code-nav, .gemini/skills/code-nav, .github/skills/code-nav and .opencode/skills/code-nav in your project.
What does Code Nav need to run?
SKILL.md names no scripts, command-line tools or credentials: Code Nav is instructions for the agent only.
Does Code Nav access the network?
SKILL.md contains no URLs. Any network use would come from the scripts or tools the agent runs. This is read from the text; nothing was executed.
Is Code Nav safe to install?
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
What licence does Code Nav use?
Code Nav has a licence file (the repository's licence) that doesn't match a standard licence. Read it on GitHub before reusing the skill.
How many tokens does Code Nav use?
About 460 tokens (SKILL.md is roughly 1.8k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 2.4k tokens, read only when the agent opens those files.
What are the alternatives to Code Nav?
Skills that share tags, products or a category with Code Nav: Nav Start (qf-studio/navigator, 354 stars), Nav Compact (qf-studio/navigator, 354 stars), Nav Diagnose (qf-studio/navigator, 354 stars) and Nav Features (qf-studio/navigator, 354 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Code Nav?
ncatbot (a GitHub organization) maintains it in ncatbot/NcatBot, which has 115 GitHub stars. The repository holds 12 skills in this directory. The repository was last updated on October 4, 2026.
