A CLI for Reddit — browse feeds, read posts, search, and interact via reverse-engineered API 📖

English | 中文

Features

• 🔐 Auth — auto-extract browser cookies, status check, whoami
• 🏠 Feed — browse home feed, popular, /r/all, and subscription-only feed (--subs-only)
• 📋 Subreddits — browse any subreddit with sort/time filters, view subreddit info
• 📰 Posts — read posts and comment trees with syntax highlighting
• 💬 Expanded comments — --expand-more loads additional more comments entries
• 🔢 Short-index navigation — rdt show 3 to read, rdt open 3 to browser
• 🔍 Search — full-text search with subreddit, sort, and time filters
• 📤 Export — export search results to CSV or JSON; -o file.json on any listing
• 👤 Users — view user profiles, post history, comment history, saved and upvoted items
• ⬆️ Interactions — upvote/downvote, save/unsave, subscribe/unsubscribe, comment (with 1.5-4s rate-limit delay)
• 🛡️ Anti-detection — consistent Chrome 133 fingerprint, sec-ch-ua alignment, Gaussian jitter, exponential backoff
• 📊 Structured output — --yaml, --json, --output FILE, --compact, --full-text
• 📦 Stable envelope — see SCHEMA.md for ok/schema_version/data/error
• 🤖 Agent-friendly — Rich output on stderr, --compact for token-efficient output

AI Agent Tip: Prefer --yaml for structured output unless strict JSON is required. Non-TTY stdout defaults to YAML automatically. Use --compact to reduce token usage.

Authentication

rdt-cli supports browser cookie extraction to authenticate with Reddit:

1. Saved cookies — loads from ~/.config/rdt-cli/credential.json
2. Browser cookies — auto-detects installed browsers and extracts cookies (supports Chrome, Firefox, Edge, Brave)

rdt login automatically tries all installed browsers and uses the first one with valid cookies.

Cookie TTL

Saved cookies are valid for 7 days by default. After that, the client automatically attempts to refresh from the browser. If browser extraction fails, the existing cookies are used with a warning.

Short-Index Navigation

After any listing command such as feed, popular, all, sub, or search, the CLI stores the latest ordered post list in ~/.config/rdt-cli/index_cache.json.

• rdt show <N> reads the Nth post from the latest listing
• rdt open <N> opens the Nth post in the browser
• rdt upvote <N>, rdt save <N>, rdt comment <N> reuse the same short index
• Empty listings clear the index cache, so old results are not reused by accident

Environment Variables

Variable	Default	Description
OUTPUT	auto	Output format: json, yaml, rich, or auto (→ YAML when non-TTY)

Rate Limiting & Anti-Detection

rdt-cli includes anti-detection measures designed to minimize risk:

Request Timing

• Gaussian jitter: Delays between requests use a truncated Gaussian distribution (~1s mean, σ=0.3)
• Random long pauses: ~5% of requests include an additional 2-5 second delay simulating reading behavior
• Auto-retry: Exponential backoff on HTTP 429/5xx and network errors (up to 3 retries)

Browser Fingerprint Consistency

• UA/Platform alignment: User-Agent, sec-ch-ua, sec-ch-ua-platform, sec-ch-ua-mobile are all consistent (Chrome 133)
• Cookie merge: Set-Cookie headers from Reddit responses are merged back into the session

Structured Output

All --json / --yaml output uses the shared envelope from SCHEMA.md:

ok: true
schema_version: "1"
data: { ... }

When stdout is not a TTY (e.g., piped or invoked by an AI agent), output defaults to YAML. Use OUTPUT=yaml|json|rich|auto to override.

Use as AI Agent Skill

rdt-cli ships with a SKILL.md that teaches AI agents how to use it.

Troubleshooting

Q: No Reddit cookies found

1. Open any browser and visit https://www.reddit.com/
2. Log in with your account
3. Run rdt login (auto-detects browser)

Q: database is locked

Close the browser Cookie database lock — close browser, then retry rdt login.

Q: Session expired

Your cookies have expired. Run rdt logout && rdt login to refresh.

Q: Rate limited

Wait and retry; the built-in exponential backoff handles this automatically.

Q: Requests are slow

The built-in Gaussian jitter delay (~1s between requests) is intentional to mimic natural browsing and avoid triggering Reddit's rate limiting.

认证策略

rdt-cli 支持浏览器 Cookie 提取来认证 Reddit：

1. 已保存 Cookie — 从 ~/.config/rdt-cli/credential.json 加载
2. 浏览器 Cookie — 自动检测已安装浏览器并提取（支持 Chrome、Firefox、Edge、Brave）

Cookie 保存后有效期 7 天，超时后自动尝试从浏览器刷新。

常见问题

• No Reddit cookies found — 请先在任意浏览器打开 https://www.reddit.com/ 并登录，然后执行 rdt login
• database is locked — 关闭浏览器后重试
• Session expired — Cookie 过期，执行 rdt logout && rdt login 刷新
• Rate limited — 等待重试，内置指数退避会自动处理
• 请求较慢是正常的 — 内置高斯随机延迟（~1s）是为了模拟人类浏览行为，避免触发限速
