Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

fetch-twitter scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Fetch Twitter/X Content

Fetch tweet content using Twitter's syndication API (the same endpoint used for tweet embeds).

Quick Usage

bun ~/.config/opencode/skill/fetch-twitter/fetch-twitter.js <tweet_url_or_id>

Examples

# From full URL
bun ~/.config/opencode/skill/fetch-twitter/fetch-twitter.js https://x.com/shanselman/status/2006301298933604666

# From tweet ID only
bun ~/.config/opencode/skill/fetch-twitter/fetch-twitter.js 2006301298933604666

Output Format

{
  "id": "2006301298933604666",
  "url": "https://x.com/shanselman/status/2006301298933604666",
  "author": {
    "name": "Scott Hanselman",
    "handle": "@shanselman",
    "verified": true
  },
  "text": "Full tweet text...",
  "created": "2025-12-31T09:47:59.000Z",
  "favorites": 389,
  "hasMedia": false,
  "mediaType": null,
  "quotedTweet": {
    "author": "@davidfowl",
    "text": "Quoted tweet text...",
    "url": "https://x.com/davidfowl/status/..."
  }
}

How It Works

Twitter's syndication API (cdn.syndication.twimg.com) is used for tweet embeds and doesn't require authentication. It requires a token calculated from the tweet ID:

function getToken(id) {
  return ((Number(id) / 1e15) * Math.PI)
    .toString(36)
    .replace(/(0+|\.)/g, '');
}

The endpoint is: https://cdn.syndication.twimg.com/tweet-result?id={tweetId}&token={token}

Limitations

  • May occasionally fail (retry if needed)
  • Rate limits are undocumented
  • Could break if Twitter changes the embed system
  • Does not fetch full threads, only the specific tweet (plus quoted tweet if present)

When to Use

When processing Twitter URLs:

  1. Detect x.com or twitter.com URLs
  2. Run: bun ~/.config/opencode/skill/fetch-twitter/fetch-twitter.js <url>
  3. Parse the JSON output
  4. Use text, author.name, author.handle for the markdown entry
  5. Note hasMedia and mediaType if relevant
  6. Include quotedTweet context if present

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
