At a glance

Decide whether a page needs external changes before refresh, then use the opt-in shared SSE and polling transport safely.

  • Works in 2 steps: The data can change without the current… → The user needs to see that change before…

  • SKILL.md covers Decision rule, Cost and behavior, Use the hook and Query freshness, plus 2 more sections
  • Instructions only: no scripts, shell commands, URLs or credentials in SKILL.md

What it does

Real Time Sync is an agent skill from BuilderIO/agent-native. Decide whether a page needs external changes before refresh, then use the opt-in shared SSE and polling transport safely.

Its SKILL.md is about 1.5k 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 Backend & APIs. The repository describes itself as: A framework for building agentic apps.

When your agent uses it

  • Backend & APIs work in your project

Example prompts

  • “/real-time-sync”

Workflow steps

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

  1. The data can change without the current user acting.
  2. The user needs to see that change before refreshing or navigating.

What it can do on your machine

Read from SKILL.md and the folder at commit be0d784. 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 typescript).

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

  • Network

    No URLs in SKILL.md.

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

  • Credentials

    Names no API keys, tokens, secrets or passwords.

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

Context cost

Real Time Sync loads about 1.5k tokens when it runs. Until then it costs about 34 tokens; SKILL.md has 811 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~34
When it runs · the whole SKILL.md, loaded when a task matches
~1.5k

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 811 words (~1,542 tokens).
