Guidance for querying ML model leaderboards and benchmarks (MTEB, HuggingFace, embedding benchmarks).

  • Works in 9 steps: Identify Authoritative Data Sources → Verify Temporal Alignment → Access Live Leaderboard Data → …
  • Tasks that involve Embeddings
  • SKILL.md covers When to Use This Skill, Core Approach, Verification Strategies and Common Pitfalls to Avoid, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Mteb Leaderboard is an agent skill from lazyFrogLOL/Harness_Engineering. Guidance for querying ML model leaderboards and benchmarks (MTEB, HuggingFace, embedding benchmarks). This skill applies when tasks involve finding top-performing models on specific benchmarks, compar

Its SKILL.md is about 2.1k tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.

It sits in AI & LLM Engineering, covering Embeddings, Model hubs and datasets and Machine learning. It works with Hugging Face and GitHub.

When your agent uses it

  • Tasks that involve Embeddings
  • Tasks that involve Model hubs and datasets
  • Tasks that involve Machine learning

Example prompts

  • “/mteb-leaderboard”

Workflow steps

9 steps, taken from the step headings in SKILL.md.

  1. Identify Authoritative Data Sources
  2. Verify Temporal Alignment
  3. Access Live Leaderboard Data
  4. Validate Model Eligibility
  5. Relying on Outdated Academic Papers
  6. Giving Up When Web Scraping Fails
  7. Making Assumptions About Model Format
  8. Premature Conclusion Without Verification
  9. Ignoring Temporal Requirements

What it can do on your machine

Read from SKILL.md and the folder at commit cae3b25. 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

Mteb Leaderboard loads about 2.1k tokens when it runs. Until then it costs about 54 tokens; SKILL.md has 1,064 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~54
When it runs · the whole SKILL.md, loaded when a task matches
~2.1k

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 1,064 words (~2,062 tokens).

“This skill provides guidance for accurately querying machine learning model leaderboards and benchmarks, particularly the Massive Text Embedding Benchmark (MTEB) and related embedding leaderboards.”
