memory-allocator-from-scratch

Fine to try.

By yanacuti1121/Yana-AI (GitHub) · coding · 13 stars · scanned at commit 54d4aa9

Use when implementing a custom malloc/free-style memory allocator from first principles — not when just using a language's built-in allocator. Triggers on: 'write a malloc implementation', 'build a memory allocator', 'free list allocator', 'buddy allocator', 'slab allocator', 'implement my own malloc/free'. Covers free-list design, block metadata, coalescing, alignment, and allocator strategy tradeoffs.

Works with any agent that supports SKILL.md skills.

What this skill can do

We found nothing in the files we read that matches our rules. That does not prove the skill is safe: see the limits of static scanning.

Install

Paste this into your terminal. It downloads exactly the version we scanned, not whatever is newest.

if [ -e ~/.agents/skills/'memory-allocator-from-scratch' ] || [ -L ~/.agents/skills/'memory-allocator-from-scratch' ]; then echo 'A skill folder named memory-allocator-from-scratch already exists — not replacing it' >&2; false; else d=$(mktemp -d) && git clone --quiet --filter=blob:none --no-checkout 'https://github.com/yanacuti1121/Yana-AI' "$d" && git -C "$d" checkout --quiet '54d4aa9fa3241319f4d37212bd23826658bf6bed' -- '.claude/skills/memory-allocator-from-scratch' && mkdir -p ~/.agents/skills && cp -R "$d"/'.claude/skills/memory-allocator-from-scratch' ~/.agents/skills/'memory-allocator-from-scratch' && rm -rf "$d"; fi

Codex reads ~/.agents/skills directly. For Claude Code, Cursor, Copilot, Gemini CLI, Antigravity or OpenCode, also link it. For Claude Code: ln -s ~/.agents/skills/'memory-allocator-from-scratch' ~/.claude/skills/'memory-allocator-from-scratch' (other agents: ~/.cursor/skills, ~/.copilot/skills, ~/.gemini/skills, ~/.gemini/config/skills, ~/.config/opencode/skills). Or install through the finder skill, which does both.
