X Npi is an agent skill from BLANK2077/xverif. 当 AI agent 需要使用 Synopsys pynpi 编写 Python 脚本,进行批量 FSDB 波形统计、值扫描、APB/AXI/valid-ready stream 协议分析、VCS/Verdi coverage database 查询,或静态设计 driver/load 查询时使用。离线大规模分析脚本和报告优先使用本 skill;xdebug 风格的实时 active-driver 根因定位或 PVC active-driver 检查不要使用本 skill。
Its SKILL.md is about 1.4k tokens, which your agent loads only when the skill is triggered. The skill folder holds 30 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/coverage-patterns.md` and `references/design-trace-patterns.md`).
It works with Python. The repository describes itself as: xverif is a local toolkit for chip-verification debug agents. It contains deterministic tools for design and waveform debug, coverage, bit calculations, structured entry…. The licence is MIT.
Read from SKILL.md and the folder at commit 25bb715. 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.
Ships 9 files in scripts/ (Python, from the files we listed), which the agent can run.
From the folder's file list and the shell code blocks in SKILL.md.
No URLs in SKILL.md.
From 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.
X Npi loads about 1.4k tokens when it runs, and up to ~6.4k if it reads all its reference files. Until then it costs about 61 tokens; SKILL.md has 377 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); the scripts in this folder are not scanned.

Run `npx skills add BLANK2077/xverif --skill x-npi -a claude-code`. Or copy the skill folder (skills/x-npi in BLANK2077/xverif) into .claude/skills/x-npi in your project. Claude Code loads it when a task matches its description.
Run `npx skills add BLANK2077/xverif --skill x-npi -a codex`. Or copy the skill folder (skills/x-npi in BLANK2077/xverif) into .agents/skills/x-npi 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 BLANK2077/xverif --skill x-npi -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/x-npi, .gemini/skills/x-npi, .github/skills/x-npi and .opencode/skills/x-npi in your project.
Going by SKILL.md and its folder, X Npi needs Python for the scripts in its folder. Our summary lists: Python 3.
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.
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. The check reads SKILL.md only: the scripts in the folder are not scanned, so read them before running anything.
X Npi is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 1.4k tokens (SKILL.md is roughly 5.5k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full. Its references folder adds about 5k tokens, read only when the agent opens those files.
Skills that share tags, products or a category with X Npi: MCP Server Builder (anthropics/skills, 180k stars), PDF Processing (anthropics/skills, 180k stars), NotebookLM Research Assistant (PleasePrompto/notebooklm-skill, 7.8k stars) and Manim Video Production (browser-use/video-use, 29k stars). The comparison table on this page puts their stars, adoption, token cost, safety result and licence side by side.
BLANK2077 (a GitHub user) maintains it in BLANK2077/xverif, which has 108 GitHub stars. The repository holds 5 skills in this directory. The repository was last updated on October 10, 2026.
