## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability ruby-gems-update-digest-llm-brief-5622332a
```

Example prompt: Give me an LLM-written digest of the most consequential Ruby gem updates and breaking changes since January 1, 2025, including any upgrade guidance I should know about.

## When to prefer this

Use this endpoint when you need a concise, human-readable AI-written summary of Ruby gem changes and breaking updates — especially useful for developer newsletters, automated dependency monitoring, or keeping a Ruby/Rails project up-to-date without manually reviewing all gem changelogs. Prefer this over raw gem changelog APIs when you want curated, actionable upgrade guidance rather than raw data.

## Known failure modes

- Invalid 'since' datetime format returns a 400 or validation error
- No gem changes found in the window may return an empty or minimal brief
- LLM generation failure may fall back to a template-based brief (generatedBy: template)
- Payment not completed results in 402 Payment Required
- Service downtime on Railway returns 5xx errors

## How this service works

Plain-English digest of the Ruby gem ecosystem: which tracked packages (rails, rack, puma, sidekiq, and more) shipped notable or breaking major releases since T, why they matter, and whether to bump your Gemfile.

## Output

A JSON object containing a 'brief' field with an LLM-written narrative summarizing the most impactful Ruby gem updates and breaking changes in the requested window, a 'generatedBy' field indicating whether the content was LLM-generated or template-based, and a 'basedOnChanges' integer indicating how many gem changes were analyzed.
