What it does

Event Data is an agent skill from rubyevents/rubyevents. Guide for handling event data. Use when asked to update event data such as CFPs, Talks, Schedule, Sponsors, Involvements, or Videos. Use when updating any file in the /data/ directory.

Its SKILL.md is about 1.9k tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `TEMPLATE.md`).

It works with Ruby. The repository describes itself as: On a mission to index all Ruby events.

When your agent uses it

  • Asked to update event data such as CFPs
  • Updating any file in the /data/ directory

Example prompts

  • “/event-data”

Workflow steps

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

  1. Prefer the speaker's parameterized name as the slug (e.g., slug: "chris-hasinski" for name: "Chris Hasiński").
  2. If the name cannot be parameterized cleanly, use the speaker's GitHub handle as the slug (most common with Japanese names, eg. "河野十行"…
  3. Only transliterate when the speaker has no GitHub handle.

What it can do on your machine

Read from SKILL.md and the folder at commit 29dd175. 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:

    • rails

    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

Event Data loads about 1.9k tokens when it runs. Until then it costs about 49 tokens; SKILL.md has 1,022 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~49
When it runs · the whole SKILL.md, loaded when a task matches
~1.9k

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 1,022 words (~1,914 tokens).

“If something is unclear, use the AskUserTool to ask for clarification. Always use the generators of MCP tools if possible. The generators/mcp tools will create a file with the correct structure, and will help you avoid formatting errors. If you…”
