x-thread-reader

A set of project structures and development guidance for FastAPI, a Python framework for building web APIs. It covers asynchronous code, dependency injection, middleware, error handling, databases, and testing.

In plain words
What is it for?
Use it when creating FastAPI applications, REST APIs, microservices, or async services connected to PostgreSQL or MongoDB.
Why use it?
It gives a new backend project an organised starting point, so common application pieces do not have to be designed from scratch.

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

x-thread-reader 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 2d 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

X Thread Reader

Use this skill whenever an X/Twitter post may need more than the top-post text.

Workflow

  1. Extract the tweet id from the URL.

    • Match x.com/<user>/status/<id>, twitter.com/<user>/status/<id>, or equivalent status URLs.
    • Ignore query parameters such as ?s=20.
  2. Build the thread-reader URL:

    https://twitter-thread.com/t/<tweet_id>
    
  3. Fetch the Twitter Thread Reader page before drawing conclusions from a single X post.

    • Use it to recover the thread text, tweet count, linked media alt text, quoted/replied context, and embedded links when available.
    • Cite the thread-reader URL in the final answer when it shaped the answer.
  4. Fall back only if Twitter Thread Reader fails or is missing tweets.

    • Try api.fxtwitter.com, cdn.syndication.twimg.com/tweet-result, X embed/oEmbed, web search, or browser-rendered inspection as appropriate.
    • State uncertainty when mirrors fail or only partial text is available.

Output Rules

  • Do not infer a thread's meaning from the opening tweet alone when a thread-reader page is available.
  • When comparing a thread to a local project, read the thread first, then compare it against the relevant local docs or code.
  • Preserve exact user output contracts. For title/capture tasks, return only the requested title format.
  • Avoid guessed content. If the full thread cannot be verified, say what was verified and what was not.

Changes

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.

x-thread-reader is a skill published in the GitHub repository tokenbender/agent-guides (368 stars, last pushed 1mo ago), licensed Apache-2.0. It adds 66 tokens to every session and 460 once invoked, about $0.0003 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
