description

Interact with Reddit — browse subreddits, read posts and comments, search content, view user profiles, post comments, vote, save posts, subscribe to subreddits. Use this skill whenever the user mentions Reddit, r/, subreddit, wants to browse Reddit posts, read Reddit discussions, search Reddit, look up Reddit users, or interact with Reddit content. Also trigger when the user pastes a Reddit URL (e.g. reddit.com/r/programming/...) or mentions a subreddit name.

Reddit

Browse subreddits, read posts and comments, search content, view user profiles, and interact with Reddit.

Skill Directory

<SKILL_DIR> is the directory containing this SKILL.md file. Determine it ONCE at the start and reuse it.

Setup (run FIRST — every time, before any operation)

You MUST complete this setup before running any script. Do NOT skip this step.

sig status reddit 2>&1

Check the JSON output fields configured and valid:

• configured: false → run Provider Setup below. Do NOT proceed without completing it.
• valid: false (but configured: true) → run sig login reddit, then re-check.
• valid: true → detect proxy (see below), then execute the user's request.

Provider Setup

1. Read <SKILL_DIR>/references/provider-config.yaml
2. Append the provider block to ~/.sig/config.yaml under providers:
3. Ask the user: "Do you need a proxy to access this site?" — if yes, add networkProxy: <url> under the provider in config.yaml
4. Run sig login reddit (with --network-proxy <url> if proxy was specified)
5. Verify: run sig status reddit again — must show valid: true before proceeding

Proxy Detection (after provider is valid)

grep -A15 "^\s*reddit:" ~/.sig/config.yaml | grep networkProxy | awk '{print $2}'

If this outputs a URL, prefix ALL python3 commands with HTTPS_PROXY=<url> HTTP_PROXY=<url>. If using socks5, convert to socks5h for python (e.g. socks5://... → socks5h://...). If empty, no proxy needed.

Running Scripts

All scripts require setup to be completed first (see above).

Read operations — use sig run to inject cookie (enables authenticated features):

sig run reddit -- bash -c 'python3 <SKILL_DIR>/scripts/reddit_hot.py --cookie "$SIG_REDDIT_COOKIE" --subreddit programming --limit 10'

Write operations — require sig run (cookie is mandatory):

sig run reddit -- bash -c 'python3 <SKILL_DIR>/scripts/reddit_comment.py --cookie "$SIG_REDDIT_COOKIE" --parent t3_1abc --text "Great post!"'

Env var: SIG_REDDIT_COOKIE

On auth error (401/403): run sig login reddit automatically (no user prompt), then retry.

Safety

Always show the user the title/body and get explicit confirmation before calling reddit_submit.py or reddit_comment.py. Posts and comments are public. Posts can be edited/deleted via reddit_manage.py.

reddit_vote.py and reddit_subscribe.py are reversible — use --direction none to remove a vote, --undo to unsubscribe.

Key Concepts

Subreddit names — Always pass without the r/ prefix. Use programming not r/programming.

Post IDs — reddit_post.py accepts: bare ID (1k2x3y), fullname (t3_1k2x3y), full URL (https://www.reddit.com/r/python/comments/1k2x3y/...), or short link (https://redd.it/1k2x3y).

Fullnames — Reddit identifies objects with type prefixes: t1_ (comment), t3_ (post). Write scripts accept bare IDs or fullnames.

OAuth Bearer — Write operations use the token_v2 cookie value as a Bearer token against oauth.reddit.com. The client extracts it automatically from the session cookie.

Time periods — Used by reddit_top.py and reddit_search.py. Valid: hour, day, week, month, year, all.

Pagination — List endpoints return an after token. Pass it as --after on the next call to get the next page.

NSFW content — Posts flagged as NSFW include "over_18": true in the response.

Timeout	Network blocked or slow	Check proxy config; retry with HTTPS_PROXY
ConnectionError	Can't reach reddit.com	Proxy is missing or wrong; check ~/.sig/config.yaml
