multi-demo is a skill for Claude Code, Codex from JustVugg/tools-factory. It costs 56 tokens per session (337 once invoked), scanned A, original, MIT.

A local command-line aggregator that combines results from ESPN basketball scoreboards and Open-Meteo weather forecasts. An aggregator collects information from multiple services into one result.

In plain words
What is it for?
Use it to request data from both sources at once and receive one merged, ranked JSON result.
Why use it?
It removes the need to call and combine these two public services separately.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

multi-demo scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 7d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Multi-source demo aggregator

Generated by Gutenberg. Use this skill to run the local multi-demo aggregator CLI across multiple API sources and return one merged JSON result.

When to use

  • The user asks for a cross-source view covered by espn, open-meteo.
  • An agent task needs one command that fans out to multiple APIs and ranks or merges the results.

How to invoke

multi-demo sources
multi-demo fan-out --json
multi-demo fan-out --param key=value --json

Sources

Output contract

  • sources lists the embedded source manifests.
  • fan-out --json returns merged/ranked items from each source.
  • Source-specific credentials use each source env prefix, not the aggregator prefix.

Provenance

  • Schema: gutenberg.aggregator-manifest.v1
  • Merge strategy: concatenate
  • Rank strategy: by-source-order
  • Example source: espn getApisSiteV2SportsBasketballNbaScoreboard
Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
