What it does
D2mcpp Authoring is an agent skill from mcpp-community/d2mcpp. Authoring conventions, design principles, and file formats for the d2mcpp (D2X) Modern C++ tutorial project. Use this whenever you add or edit a C++ language-feature lesson — a book chapter, an exercise, a reference solution, or when registering them in SUMMARY/changelog. Trigger it for any request like "add a chapter for X", "write an exercise for fold expressions", "add the constexpr lesson", "fill the cpp14 section", or anything touching book/src, book/en/src, src/ (exercises), or solutions/. Even small edits…
Its SKILL.md is about 2.7k tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including reference files and assets (for example `assets/chapter.en.md`, `assets/chapter.zh.md` and `references/anatomy.md`).
It sits in Development, covering Translation and Changelog and release notes. It works with C++. The repository describes itself as: D2X | Modern C++ Core Language Features - "A C++ tutorial project focused on practical".
When your agent uses it
- It for any request like add a chapter for X
- Write an exercise for fold expressions
- Add the constexpr lesson
- Fill the cpp14 section
Example prompts
- “add a chapter for X”
- “write an exercise for fold expressions”
- “add the constexpr lesson”
- “/d2mcpp-authoring”
Workflow steps
8 steps, taken from the first numbered list in SKILL.md.
- book/src//NN-topic.md — zh chapter
- book/en/src//NN-topic.md — en chapter (translate prose, keep code identical)
- src//tests/NN-topic/K.cpp — one or more exercises (K = 0,1,2…), zh comments
- src/en//tests/NN-topic/K.cpp — en exercises (translate comments only)
- solutions/tests//NN-topic/K.cpp — reference solution per exercise (zh/en 共用)
- (nothing to register — exercises are tests, discovered by directory convention)
- Add the chapter line to both book/src/SUMMARY.md and book/en/src/SUMMARY.md
- Add a changelog entry to both book/src/changelog.md and book/en/src/changelog.md
What it can do on your machine
Read from SKILL.md and the folder at commit 6bcf5db. 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
D2mcpp Authoring loads about 2.7k tokens when it runs, and up to ~4k if it reads all its reference files. Until then it costs about 157 tokens; SKILL.md has 1,333 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 1,333 words (~2,722 tokens).
“d2mcpp teaches Modern C++ core language features through a tightly coupled quartet: Book (mdBook) + Code (exercises-as-tests) + Solution + Auto-checker (d2x checker / native mcpp test), all of it bilingual (zh + en). A "lesson" is never one file…”
