About this skill
Cache Codebase is a skill in kurealnum/dotfiles (290 stars). Its SKILL.md is about 817 tokens. No licence found.
Workflow steps
2 steps, taken from the first numbered list in SKILL.md.
- Update the date modified
- Reread the real file and update all other fields
What it can do on your machine
Read from SKILL.md and the folder at commit bcd8741. 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 (its code samples are markdown).
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
Cache Codebase loads about 817 tokens when it runs. Until then it costs about 14 tokens; SKILL.md has 416 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 416 words (~817 tokens).
“Reduce token usage by reading off a minimized version of a given codebase.”

Questions about Cache Codebase
How do I install Cache Codebase in Claude Code?
Run `npx skills add kurealnum/dotfiles --skill cache-codebase -a claude-code`. Or copy the skill folder (.agents/skills/cache-codebase in kurealnum/dotfiles) into .claude/skills/cache-codebase in your project. Claude Code loads it when a task matches its description.
How do I install Cache Codebase in Codex?
Run `npx skills add kurealnum/dotfiles --skill cache-codebase -a codex`. Or copy the skill folder (.agents/skills/cache-codebase in kurealnum/dotfiles) into .agents/skills/cache-codebase in your project. Codex loads it when a task matches its description.
Can I use Cache Codebase 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 kurealnum/dotfiles --skill cache-codebase -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/cache-codebase, .gemini/skills/cache-codebase, .github/skills/cache-codebase and .opencode/skills/cache-codebase in your project.
What does Cache Codebase need to run?
SKILL.md names no scripts, command-line tools or credentials: Cache Codebase is instructions for the agent only.
Does Cache Codebase access the network?
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.
Is Cache Codebase 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 Cache Codebase use?
No licence was found for Cache Codebase or its repository. Without one, default copyright applies: ask the author before reusing or redistributing it.
How many tokens does Cache Codebase use?
About 817 tokens (SKILL.md is roughly 3.3k 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 Cache Codebase?
Skills that share tags, products or a category with Cache Codebase: Context Compression (guanyang/open-agent-hub, 973 stars), Bounty Hunter (1sadjlk/bounty-hunter-skill, 282 stars), Skill Shortener (luongnv89/asm, 953 stars) and Fleet Auditor (alexgreensh/token-optimizer, 2.5k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Cache Codebase?
kurealnum (a GitHub user) maintains it in kurealnum/dotfiles, which has 290 GitHub stars. The repository holds 13 skills in this directory. The repository was last updated on April 13, 2026.
