build-accelerationBuild acceleration skill for C/C++ projects. An agent skill from mohitmishra786/low-level-dev-skills.
Build Acceleration is an agent skill from mohitmishra786/low-level-dev-skills. Build acceleration skill for C/C++ projects. Use when reducing compilation times with ccache, sccache, distcc, unity builds, precompiled headers, split DWARF, or IWYU. Covers caching strategies, distributed compilation, link time reduction, and diagnosing build bottlenecks. Activates on queries about slow builds, ccache, sccache, precompiled headers, unity builds, split-DWARF, or reducing C++ compile times.
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including reference files (for example `references/ccache-config.md`).
It sits in Game Development, covering Caching. It works with C++ and Rust. The repository describes itself as: A curated suite of AI agent skills for systems and low-level programming with C/C++, Rust, and Zig toolchains, covering compilers, debuggers, profilers, build systems…. The licence is MIT.
8 steps, taken from the step headings in SKILL.md.
Read from SKILL.md and the folder at commit bdc5847. It shows what the files ask for, not the result of running them.
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.
Shell commands in SKILL.md call:
cmakeapt-getbrewcargomakeFrom the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Build Acceleration loads about 1.4k tokens when it runs, and up to ~2.2k if it reads all its reference files. Until then it costs about 107 tokens; SKILL.md has 284 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.
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.

Split DWARF puts debug info in .dwo sidecar files, dramatically reducing what the linker must process.

Build Acceleration fits situations like: reducing compilation times with ccache; precompiled headers.
Run `npx skills add mohitmishra786/low-level-dev-skills --skill build-acceleration -a claude-code`. Or copy the skill folder (skills/build-systems/build-acceleration in mohitmishra786/low-level-dev-skills) into .claude/skills/build-acceleration in your project. Claude Code loads it when a task matches its description.
Run `npx skills add mohitmishra786/low-level-dev-skills --skill build-acceleration -a codex`. Or copy the skill folder (skills/build-systems/build-acceleration in mohitmishra786/low-level-dev-skills) into .agents/skills/build-acceleration in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add mohitmishra786/low-level-dev-skills --skill build-acceleration -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/build-acceleration, .gemini/skills/build-acceleration, .github/skills/build-acceleration and .opencode/skills/build-acceleration in your project.
Going by SKILL.md and its folder, Build Acceleration needs the command-line tools its instructions call (cmake, apt-get, brew, cargo and make).
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.
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.
Build Acceleration is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.8k 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 739 tokens, read only when the agent opens those files.
Skills that share tags, products or a category with Build Acceleration: Gdextension (jame581/GodotPrompter, 805 stars), New Effect Node (n1m21n/Infinite, 271 stars), SeekDB Code Review (oceanbase/seekdb, 3.1k stars) and Fory Version Bump (apache/fory, 4.6k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
