Calls cmake, git and bash

What it does

Asan is an agent skill from thun-res/vlink. 以 AddressSanitizer(ENABLETESTSANITIZE=ON)构建并运行 vlink-test 单元测试,复现 CI 的 ASan 门禁。用户要求"跑 asan"、"内存检测测试"、排查 ci-test 的 sanitize 失败时使用。

Its SKILL.md is about 680 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `agents/openai.yaml`).

It works with C++. The repository describes itself as: VLink is a high-performance C++ communication middleware for autonomous driving and embodied intelligence, positioned as a full-scenario alternative to ROS 2. The licence is Apache-2.0.

Example prompts

“跑 asan”
“内存检测测试”
“/asan”

Workflow steps

2 steps, taken from the step headings in SKILL.md.

执行
结果处理

What it can do on your machine

Read from SKILL.md and the folder at commit 1793889. 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
Shell commands in SKILL.md call:
- cmake
- git
- bash
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md. Its commands use git, which can reach the network depending on how they are called.
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

Asan loads about 683 tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 97 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it: ~34
When it runs · the whole SKILL.md, loaded when a task matches: ~683

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.

ASan 单元测试

ENABLE_TEST_SANITIZE=ON 时,根 CMakeLists.txt 对 vlink 库目标调用 vlink_test_sanitize()(cmake/functions/common.cmake:45),追加 -fsanitize=address 编译与链接选项;随后构建并运行 vlink-test 触发被测库代码。支持 Windows/QNX 之外的 GCC/Clang 目标;不满足条件时会告警跳过。CI 中只有 Linux job 开启此项 (.github/workflows/ci-test.yml)。

              count++
            }
            if (count > 0) {
              print count
            }
          }'
    )" || PHYSICAL_CORES=

    PHYSICAL_CORES="$(sysctl -n hw.physicalcpu 2>/dev/null)" || PHYSICAL_CORES=

esac
if [ "$PHYSICAL_CORES" -gt 1 ]; then
  BUILD_JOBS=$((PHYSICAL_CORES - 1))
else
  BUILD_JOBS=1
fi

配置(AI 专用构建目录):

bash

cmake -S "$REPO_ROOT" -B "$BUILD_DIR" \
  -DCMAKE_BUILD_TYPE=Release \
  -DENABLE_CXX_STD_20=OFF \
  -DENABLE_TEST=ON \
  -DENABLE_TEST_WARN=ON \
  -DENABLE_TEST_SANITIZE=ON \
  -DENABLE_TEST_COVERAGE=OFF \
  -DENABLE_PROXY=ON \
  -DENABLE_EXAMPLES=OFF

配置前确认 Fast DDS 或 Cyclone DDS 可被 CMake 找到。CMake 将 ENABLE_PROXY 改回 OFF 或未生成 vlink-proxy target 均为配置失败,不得继续测试。

构建:

bash

cmake --build "$BUILD_DIR" --target vlink-test vlink-proxy --parallel "$BUILD_JOBS"

运行测试。复用 CI 脚本,确保先启动测试依赖的 vlink-proxy,并沿用 CI 的超时、并行度和排除规则:

bash

export ASAN_OPTIONS=detect_odr_violation=0
cd "$REPO_ROOT"
BUILD_DIR="$BUILD_DIR_REL" bash .github/scripts/run-posix-ci-tests.sh

2. 结果处理

detect_odr_violation=0 是 CI 既有约定(共享库场景误报),不要再额外放宽 ASAN_OPTIONS。
BUILD_JOBS 必须严格等于 max(真实物理核心数 - 1, 1)。禁止改用逻辑 CPU 数、裸 --parallel/-j 或固定高并行度;无法可靠获取物理核心数时固定单核,且同一时刻只运行一个本地构建,防止编译卡死或耗尽内存。
默认 BUILD_DIR_REL 为 build-ai/skill_asan;正被其他任务使用时先改为 build-ai/skill_asan_<task_name>,再派生 BUILD_DIR,不得共用或清理其他构建目录。
ASan 报告(heap-use-after-free、leak、stack-buffer-overflow 等)一律按真实缺陷报告;用户同时要求修复时再定位并修改源码,不通过 suppression 文件消音。
只在用户显式调用本 skill 时才执行构建与测试;日常改码流程仍遵循 AGENTS.md 强制规则第 3 条(不主动构建)。

How do I install Asan in Claude Code?

Run `npx skills add thun-res/vlink --skill asan -a claude-code`. Or copy the skill folder (.agents/skills/asan in thun-res/vlink) into .claude/skills/asan in your project. Claude Code loads it when a task matches its description.

How do I install Asan in Codex?

Run `npx skills add thun-res/vlink --skill asan -a codex`. Or copy the skill folder (.agents/skills/asan in thun-res/vlink) into .agents/skills/asan in your project. Codex loads it when a task matches its description.

Can I use Asan 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 thun-res/vlink --skill asan -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/asan, .gemini/skills/asan, .github/skills/asan and .opencode/skills/asan in your project.

What does Asan need to run?

Going by SKILL.md and its folder, Asan needs the command-line tools its instructions call (cmake, git and bash).

Does Asan access the network?

SKILL.md contains no URLs. Its commands use git, which can reach the network depending on how they are called. This is read from the text; nothing was executed.

Is Asan 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 Asan use?

Asan is published under the Apache-2.0 licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.

How many tokens does Asan use?

About 683 tokens (SKILL.md is roughly 2.7k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.

What are the alternatives to Asan?

Skills that share tags, products or a category with Asan: Paddle Build (PaddlePaddle/Paddle, 24k stars), Fory Release (apache/fory, 4.6k stars), ONNX Runtime Shape Inference Safety Audit (microsoft/onnxruntime, 22k stars) and Code Audit (3stoneBrother/code-audit, 892 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.

Who maintains Asan?

thun-res (a GitHub user) maintains it in thun-res/vlink, which has 116 GitHub stars. The repository holds 16 skills in this directory. The repository was last updated on October 9, 2026.
