What it does
Leaderboard is an agent skill from karanb192/claude-code-hooks. Show this repo's context-cost leaderboard: the files that pulled the most tokens into context
Its SKILL.md is about 210 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
The repository describes itself as: 🪝 Claude Code hooks + an installable plugin marketplace: safety, cost, observability, productivity. The licence is MIT.
Example prompts
- “/leaderboard”
What it can do on your machine
Read from SKILL.md and the folder at commit 3c9c90a. 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
Shell commands in SKILL.md call:
node
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
Leaderboard loads about 208 tokens when it runs. Until then it costs about 26 tokens; SKILL.md has 85 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
The full file from karanb192/claude-code-hooks at commit 3c9c90a, republished under its MIT licence (© karanb192). 85 words, ~208 tokens.

The table above is this repository's most token-expensive files, aggregated across
your recent sessions (read count, cumulative tokens, estimated cost). It is produced
by the context-hogs hook, which records as you work.
Briefly call out the top 1-3 offenders and suggest one concrete fix each: for
example: split an oversized file, exclude a generated/vendored path, or add the
suggested CLAUDE.md / permissions.deny block for a file Claude keeps re-reading.
Keep it short; do not re-run any commands.

Questions about Leaderboard
What does Leaderboard do?
Show this repo's context-cost leaderboard: the files that pulled the most tokens into context. Leaderboard is an agent skill from karanb192/claude-code-hooks.
How do I install Leaderboard in Claude Code?
Run `npx skills add karanb192/claude-code-hooks --skill leaderboard -a claude-code`. Or copy the skill folder (plugins/context-hogs/skills/leaderboard in karanb192/claude-code-hooks) into .claude/skills/leaderboard in your project. Claude Code loads it when a task matches its description.
How do I install Leaderboard in Codex?
Run `npx skills add karanb192/claude-code-hooks --skill leaderboard -a codex`. Or copy the skill folder (plugins/context-hogs/skills/leaderboard in karanb192/claude-code-hooks) into .agents/skills/leaderboard in your project. Codex loads it when a task matches its description.
Can I use Leaderboard 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 karanb192/claude-code-hooks --skill leaderboard -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/leaderboard, .gemini/skills/leaderboard, .github/skills/leaderboard and .opencode/skills/leaderboard in your project.
What does Leaderboard need to run?
Going by SKILL.md and its folder, Leaderboard needs the command-line tools its instructions call (node).
Does Leaderboard 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 Leaderboard 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 Leaderboard use?
Leaderboard is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
How many tokens does Leaderboard use?
About 208 tokens (SKILL.md is roughly 832 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 Leaderboard?
Skills that share tags, products or a category with Leaderboard: Cost Report (ruvnet/ruflo, 74k stars), Cost Tracking (affaan-m/ECC, 276k stars), Cost Conversation (ruvnet/ruflo, 74k stars) and Cost Optimize (ruvnet/ruflo, 74k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
Who maintains Leaderboard?
karanb192 (a GitHub user) maintains it in karanb192/claude-code-hooks, which has 534 GitHub stars. The repository holds 8 skills in this directory. The repository was last updated on October 4, 2026.
