Sealeap Baize Amazon Operating Difficulty is an agent skill from xjli360/sealeap-amazon-skills. Estimate Amazon operating difficulty from comparable-product sales distribution, low-review performance, ad dependence, store constraints, returns, and inventory break-even rather than headline demand alone. Use for 产品好不好运营、评论少能卖多少、该发多少货、头部销量高但新品难做. Do not treat heuristic ratios as guarantees.
Its SKILL.md is about 560 tokens, which your agent loads only when the skill is triggered. The skill folder holds 7 other files, including scripts and reference files (for example `agents/openai.yaml`, `references/mcp-data-plan.md` and `references/playbook.md`).
It works with Model Context Protocol. The repository describes itself as: Reusable Agent Skills for Amazon product research, listings, advertising, inventory, and operations. The licence is MIT.
4 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 497d4b8. 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 1 file in scripts/ (Python), 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.
Sealeap Baize Amazon Operating Difficulty loads about 560 tokens when it runs, and up to ~2.5k if it reads all its reference files. Until then it costs about 84 tokens; SKILL.md has 120 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 xjli360/sealeap-amazon-skills --skill sealeap-baize-amazon-operating-difficulty -a claude-code`. Or copy the skill folder (amazon-skills/douyin/baize/sealeap-baize-amazon-operating-difficulty in xjli360/sealeap-amazon-skills) into .claude/skills/sealeap-baize-amazon-operating-difficulty in your project. Claude Code 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 xjli360/sealeap-amazon-skills --skill sealeap-baize-amazon-operating-difficulty -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/sealeap-baize-amazon-operating-difficulty, .gemini/skills/sealeap-baize-amazon-operating-difficulty, .github/skills/sealeap-baize-amazon-operating-difficulty and .opencode/skills/sealeap-baize-amazon-operating-difficulty in your project.
Going by SKILL.md and its folder, Sealeap Baize Amazon Operating Difficulty 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.
Sealeap Baize Amazon Operating Difficulty is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 560 tokens (SKILL.md is roughly 2.2k 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 2k tokens, read only when the agent opens those files.
