What it does

Add Data Source is an agent skill from LiorVainer/data-israel. This skill should be used when the user asks to 'add a data source', 'create a new data source', 'add a new API', 'integrate a new data provider', 'add new tools', or mentions adding Israeli government data, public data APIs, or new agents for data retrieval. Guides through the full process: requirements gathering, OpenSpec proposal creation, and implementation following the project's DataSourceDefinition pattern.

Its SKILL.md is about 2.6k 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 Agent Workflows, covering Requirements gathering. The repository describes itself as: AI agent network that connects to Israeli open data sources - ask questions in Hebrew, get answers grounded in real data with charts and sources.

When your agent uses it

  • Asks to add a data source
  • Create a new data source
  • Integrate a new data provider
  • Mentions adding Israeli government data

Example prompts

  • “add a data source”
  • “create a new data source”
  • “add a new API”
  • “/add-data-source”

Workflow steps

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

  1. Gather Requirements
  2. 5: Classify the upstream's proxy tier (BEFORE writing code)
  3. Create OpenSpec Proposal
  4. Implement
  5. Register
  6. Verify

What it can do on your machine

Read from SKILL.md and the folder at commit 6522504. 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

    Shell commands in SKILL.md call:

    • pnpm
    • npm
    • tsc
    • vitest

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

  • Network

    No URLs in SKILL.md. Its commands use pnpm and npm, which can reach the network depending on how they are called.

    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

Add Data Source loads about 2.6k tokens when it runs. Until then it costs about 108 tokens; SKILL.md has 1,105 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~108
When it runs · the whole SKILL.md, loaded when a task matches
~2.6k

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: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:76
    ipt requires `BRIGHT_DATA_PROBE_URL` in `.env` (a Bright Data proxy URL forced to a **non-Israeli** country — see `.env.

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 1,105 words (~2,635 tokens).

“Create a new data source module in src/data-sources/ following the project's established architecture. This skill gathers requirements interactively, creates an OpenSpec proposal, and implements the data source.”
