Linkfox Zhihuiya Utility Patent Image Search

What it does

When your agent uses it

• Tasks that involve Intellectual property

Example prompts

• “/linkfox-zhihuiya-utility-patent-image-search”

Requirements

• Python 3
• A credential in LINKFOX_AGENT_API_KEY
• A credential in LINKFOXAGENT_API_KEY

Workflow steps

6 steps, taken from the first numbered list in SKILL.md.

1. 1Sort by score: Always sort results by score in descending order (highest similarity first) to help users quickly identify the most…
2. 2Show complete details: When summarizing results or generating reports, include ALL of the following for each patent -- do NOT omit or…
3. 3Legal disclaimer: Always append a friendly reminder at the end of results
4. 4Score explanation: Remind users that the score represents visual similarity -- a higher score indicates a closer match, but does not…
5. 5Pagination guidance: When the total count exceeds the returned results, inform users about the total number of matching patents and guide…
6. 6Error handling: When a query fails, explain the reason and suggest adjustments (e.g., verify the image URL is publicly accessible, check…

What it can do on your machine

Read from SKILL.md and the folder at commit 38fef04. 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

  Ships 3 files in scripts/ (Python), which the agent can run.

  Shell commands in SKILL.md call:

  • python

  From the folder's file list and the shell code blocks in SKILL.md.

• Network

  Links to these hosts (documentation or services it may open):

  • skill.linkfox.com

  From URLs in SKILL.md, links to its own repository left out.

• Credentials

  Names these keys or tokens, usually read from environment variables:

  • LINKFOX_AGENT_API_KEY
  • LINKFOXAGENT_API_KEY

  From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Linkfox Zhihuiya Utility Patent Image Search loads about 2.6k tokens when it runs, and up to ~5.2k if it reads all its reference files. Until then it costs about 110 tokens; SKILL.md has 1,090 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it

~110

When it runs · the whole SKILL.md, loaded when a task matches

~2.6k

With references · SKILL.md plus every file in references/, read only if the agent opens them

~5.2k

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

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.
