Build SubSignal
NOT REALLYback to the verdict
Before step 1
you will need
- Reddit API credentials, within Reddit's terms of use
- OpenAI or Anthropic API key in .env
- Node.js 22 and a scheduler such as cron
- SQLite to remember what you have already seen
Delivery order
Scaffold the smallest runnable application and document its commands.
done whenThe project starts from a documented command in a clean checkout.
Implement the primary data model and core workflow.
done whenThe main object can be created, read and changed end to end.
Add validation, safe failure states, and persistence.
done whenBad input is refused with a readable message and nothing is left corrupted.
Cover the critical path with automated tests.
done whenThe highest-risk behavior fails the suite when it breaks.
Exercise a clean install from the README and fix every missing step.
done whenA fresh clone reaches the first successful workflow using only the README.
That is the whole plan for SubSignal. What it deliberately does not cover is below · check the gaps before you call it a replacement.
- a historical archive you cannot backfill from the live API
- ranking a lead against everything seen before, instead of judging it alone
- a curated subreddit and keyword set you did not have to discover
- deduplication and history across runs
- someone tracking Reddit API terms and rate-limit changes for you
