Subreddit pre-post check

Use before any post or link share on Reddit. Produces a go / no-go verdict with the specific rule at issue. Exact commands live in references/commands.md.

The four checks — in order, every time

1. rules — read the subreddit's rules in full. Rule violations get posts removed instantly, and repeat removals flag the account
2. community type — restricted or private means stop; only approved members can post
3. duplicate URL — check the link hasn't been submitted there before. Duplicate posts get accounts banned
4. wiki — read the community wiki's index page; many subreddits keep their real posting norms there (flair requirements, self-promo windows, karma minimums)

Then verdict: go (with any constraints — required flair, allowed thread type, timing window) or no-go (with the exact rule that blocks it and an alternative if one exists — a weekly promo thread, a comment instead of a post).

What good looks like

A great check quotes the specific rule text that governs the post and adapts the plan to it — "self-promotion allowed only in the Saturday thread, so hold until Saturday" — rather than a generic green light. What gets overlooked: karma and account-age minimums buried in wikis, and per-flair rules that differ from the sidebar. When the verdict is borderline, the answer is no — a removed post costs more than a skipped one.

MUST run all four checks before any post; skipping any one voids the verdict. NEVER greenlight a post to a restricted or private community. NEVER re-submit a URL that already exists in that subreddit.
