xint-rs（新星 RS）

xint — X Intelligence CLI (Rust)

Fast, zero-dependency binary for X/Twitter search, analysis, and engagement from the terminal. All output goes to stdout (pipe-friendly).

Security Considerations

This skill requires sensitive credentials. Follow these guidelines:

Credentials

• X_BEARER_TOKEN: Required for X API. Treat as a secret - only set in environment or .env file
• XAI_API_KEY: Optional, needed for AI analysis. Also a secret
• X_CLIENT_ID: Optional, needed for OAuth. Less sensitive but don't expose publicly
• XAI_MANAGEMENT_API_KEY: Optional, for collections management

File Writes

• This skill writes to its own data/ directory: cache, exports, snapshots, OAuth tokens
• OAuth tokens stored with restrictive permissions (chmod 600)
• Review exported data before sharing - may contain sensitive search queries

Webhooks

• The watch command supports --webhook to send data to external URLs
• Only use webhooks you control (your own servers, Slack/Discord you own)
• Don't pass sensitive URLs as webhook targets

Agent Execution Boundaries

• This file documents commands and safety limits only
• Require explicit user approval before install/clone actions
• Use only documented commands and flags
• Require explicit user approval before network-facing modes (mcp --sse, watch --webhook)

Installation

• For required tools: prefer OS package managers over curl | bash when possible
• Verify any installer scripts before running

MCP Server (Optional)

• xint mcp starts a local MCP server exposing xint commands as tools
• Default mode is stdio/local integration; no inbound web server unless --sse is explicitly enabled
• Respect --policy read_only|engagement|moderation and budget guardrails

Setup

Requires env vars (in .env or exported):

• X_BEARER_TOKEN — for search, profile, tweet, thread, trends, watch, report
• X_CLIENT_ID — for OAuth commands (bookmarks, likes, following, diff)
• XAI_API_KEY — for AI analysis (analyze, report, x-search, collections upload/search)
• XAI_MANAGEMENT_API_KEY — for collections management (list, create, ensure, add-document)

OAuth setup (one-time): xint auth setup

xAI X Search (no cookies/GraphQL)

Search X via xAI's hosted x_search tool (Responses API). No bearer token or cookies needed — only XAI_API_KEY.

# Create a queries file
echo '["AI agents", "solana"]' > queries.json

# Run search scan → markdown report + JSON payload
xint x-search --queries-file queries.json --out-md report.md --out-json raw.json

# Date range filter
xint x-search --queries-file queries.json --from-date 2026-02-01 --to-date 2026-02-15

# Domain filtering
xint x-search --queries-file queries.json --allow-domains arxiv.org,github.com
xint x-search --queries-file queries.json --exclude-domains spam.com

# Image understanding in search results
xint x-search --queries-file queries.json --vision

# Custom model
xint x-search --queries-file queries.json --model grok-4-1-fast

xAI Collections Knowledge Base

Upload documents, manage collections, and semantic-search via xAI Files + Collections APIs.

# List existing collections
xint collections list

# Create or find a collection
xint collections ensure --name "research-kb"

# Upload a file to xAI
xint collections upload --path ./report.md

# Semantic search across documents
xint collections search --query "AI agent frameworks"

# Sync a directory to a collection (upload + attach)
xint collections sync-dir --collection-name "kb" --dir ./docs --glob "*.md" --limit 50

Utilities

xint auth setup                               # OAuth setup (interactive)
xint auth setup --manual                      # Manual paste mode
xint auth status                              # Show auth info
xint auth refresh                             # Force token refresh
xint cache clear                              # Clear cached data

Output Formats

Most commands support --json for raw JSON. Search also supports:

• --jsonl — one JSON object per line (great for piping)
• --csv — spreadsheet-compatible
• --markdown — formatted for reports

Piping

xint search "topic" --jsonl | jq '.username'
xint search "topic" --json | xint analyze --pipe "summarize these"
xint search "topic" --csv > export.csv

Cost Awareness

X API costs ~$0.005/tweet read. Budget system prevents runaway costs:

• Default: $1.00/day limit
• Set custom: xint costs budget <amount>
• Watch command auto-stops at budget limit

xAI Model Pricing (per 1M tokens)

• grok-4-1-fast: $0.20 input / $0.50 output (default — best value)
