h-index-guideUnderstanding and calculating research impact metrics. An agent skill from wentorai/research-plugins.
H Index Guide is an agent skill from wentorai/research-plugins. Understanding and calculating research impact metrics
Its SKILL.md is about 1.6k 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 Research & Science, covering Academic paper search. The repository describes itself as: 350+ academic research skills, MCP configs, and plugins for Research-Claw and AI agents. The licence is MIT.
5 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit bf44b3c. 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.
No scripts in the folder and no shell commands in SKILL.md (its code samples are python).
From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
api.openalex.orgFrom 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.
H Index Guide loads about 1.6k tokens when it runs. Until then it costs about 17 tokens; SKILL.md has 463 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.

.claude/skills/h-index-guide/SKILL.md (or your agent's skills folder).Understand, calculate, and responsibly interpret bibliometric indicators including h-index, impact factor, and related metrics.
The h-index (Hirsch index) is defined as: a researcher has an h-index of h if h of their papers have each been cited at least h times.
Example: If a researcher has published 20 papers with citation counts [120, 80, 55, 40, 22, 18, 15, 12, 10, 8, 5, 3, 2, 2, 1, 1, 0, 0, 0, 0], their h-index is 10 (10 papers with at least 10 citations each).

print(f"h-index: {calculate_h_index(citations)}") # Output: 10| Metric | Definition | Advantage |

| i10-index | Number of papers with >= 10 citations | Intuitive threshold (Google Scholar uses this) |
| g-index | Largest g such that top g papers have >= g^2 total citations | Rewards highly cited papers more |
| m-quotient | h-index divided by years since first publication | Normalizes for career length |
| hI-norm | h-index divided by average number of co-authors | Adjusts for team size |

Understanding and calculating research impact metrics. An agent skill from wentorai/research-plugins. H Index Guide is an agent skill from wentorai/research-plugins.
H Index Guide fits situations like: tasks that involve Academic paper search.
Run `npx skills add wentorai/research-plugins --skill h-index-guide -a claude-code`. Or copy the skill folder (skills/literature/metadata/h-index-guide in wentorai/research-plugins) into .claude/skills/h-index-guide in your project. Claude Code loads it when a task matches its description.
Run `npx skills add wentorai/research-plugins --skill h-index-guide -a codex`. Or copy the skill folder (skills/literature/metadata/h-index-guide in wentorai/research-plugins) into .agents/skills/h-index-guide 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 wentorai/research-plugins --skill h-index-guide -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/h-index-guide, .gemini/skills/h-index-guide, .github/skills/h-index-guide and .opencode/skills/h-index-guide in your project.
SKILL.md names no scripts, command-line tools or credentials: H Index Guide is instructions for the agent only. Our summary lists: Python 3.
SKILL.md names 1 domain. In commands or code: api.openalex.org; the agent is likely to contact it when it follows the instructions. 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.
H Index Guide is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.6k tokens (SKILL.md is roughly 6.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
Skills that share tags, products or a category with H Index Guide: Read arXiv Paper (karpathy/nanochat, 59k stars), Perplexity Web Search (davila7/claude-code-templates, 33k stars), Literature Review (neflibata-feng/MyArxiv-Agent, 126 stars) and Openalex Database (neflibata-feng/MyArxiv-Agent, 126 stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
