cdd

A quick compile check for common programming projects. It detects the project type and runs its configured build or type-check command, such as the TypeScript compiler, Rust checker, or Go build.

In plain words
What is it for?
Use it as a fast check after code changes. For a broader check, it also supports a mode that adds language-server and lint checks.
Why use it?
It quickly shows whether the code still compiles and reports the first build errors without running tests.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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

cdd 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 yesterday.

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.

What it actually says

/cdd — 快速编译驱动验证

一键运行 CDD 验证循环。

工作流程

1. 自动检测项目类型

扫描当前目录,识别项目类型:

文件 项目类型 编译命令
tsconfig.json TypeScript npx tsc --noEmit --pretty
package.json (build) Node.js npm run build
*.csproj C# / Unity dotnet build --no-restore
*.uproject Unreal C++ UnrealBuildTool
Cargo.toml Rust cargo check
go.mod Go go build ./...
pyproject.toml Python pyright .
CMakeLists.txt C/C++ cmake --build build/

2. 运行编译

执行对应的编译命令,捕获输出。

3. 报告结果

CDD CHECK: [PASS ✅ / FAIL ❌]
Exit Code: X
Errors: X
Warnings: X

[如果失败,显示前 10 条错误]

4. 失败时自动建议

如果编译失败:

  • 提示用户运行 /build-fix 进入 CDD 修复循环
  • 或手动调用 build-error-resolver agent

参数

  • /cdd — 默认编译检查
  • /cdd full — 编译 + LSP + Lint(等同于 /verify full
Changes

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.

cdd is a command published in the GitHub repository zhmxiaowo/opencode-simple (2 stars, last pushed 5mo ago), licensed MIT. It adds 30 tokens to every session and 398 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
