  • Works in 6 steps: Read the current page → Generate the fields → Build the full-text attachment → …

  • Reaches saved.owenyoung.com; needs JJ_API_TOKEN

What it does

Jj is an agent skill from theowenyoung/home. Save the currently active browser page to the link collection at saved.owenyoung.com. Use when explicitly invoked as $jj, or when the user asks to bookmark or collect the current page there. Read the page without navigating, generate a concise Chinese title, SEO slug, and distinctive Chinese Markdown description, attach the complete article or main-page text as Chinese-only Markdown, match collections, create one authenticated link record, and return its clickable URL.

Its SKILL.md is about 2.5k tokens, which your agent loads only when the skill is triggered. The skill folder holds 5 other files, including reference files (for example `agents/openai.yaml`, `references/article-attachment.md` and `references/content-rules.md`).

It sits in Documents & Office. It works with JavaScript.

When your agent uses it

  • Explicitly invoked as $jj
  • The user asks to bookmark
  • Collect the current page there

Example prompts

  • “/jj”

Requirements

  • A credential in JJ_API_TOKEN

Workflow steps

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

  1. Read the current page
  2. Generate the fields
  3. Build the full-text attachment
  4. Fetch and match collections
  5. Create the link record
  6. Return the result

What it can do on your machine

Read from SKILL.md and the folder at commit 9bf3ea9. 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 (its code samples are json and markdown).

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

  • Network

    Hosts in commands or code, which the agent is likely to contact:

    • saved.owenyoung.com

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

  • Credentials

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

    • JJ_API_TOKEN

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

Context cost

Jj loads about 2.5k tokens when it runs, and up to ~4.7k if it reads all its reference files. Until then it costs about 119 tokens; SKILL.md has 1,260 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~119
When it runs · the whole SKILL.md, loaded when a task matches
~2.5k
With references · SKILL.md plus every file in references/, read only if the agent opens them
~4.7k

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 1,260 words (~2,466 tokens).

“Create exactly one link record for the page that is active when the user invokes $jj.”
