Claude Code Skills Marketplace is a collection and marketplace of skills, plugins, agents, and instructions that extend Claude Code with specialized development workflows. It is for developers who want to install existing workflows or create, validate, and package their own Claude Code skills.
Getting it into your agent
It runs from inside its repository, so the clone comes first — what it calls does not travel with the file alone.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

- Snyk warn
- NVIDIA SkillSpector warn
SkillSpector: 2 findings, up to high
These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →
- high Supply Chain · line 18 Remote code is downloaded and executed. This bypasses code review and could introduce malicious code.Fix: Avoid downloading and executing remote scripts. Use trusted packages from PyPI/npm. If remote fetch is required, verify checksums and use HTTPS.
- medium Data Exfiltration · line 18 Data is being sent to an external URL. This could be legitimate telemetry or data exfiltration. Manual review is recommended.Fix: Verify the destination URL is trusted and necessary. Remove or replace with documented APIs. Ensure no secrets, tokens, or PII are transmitted.
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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00076 | $0.01363 |
| Opus 5 | $0.00038 | $0.00681 |
| Sonnet 5 | $0.00015 | $0.00273 |
| Haiku 4.5 | $0.00008 | $0.00136 |
Grade A, and why
twitter-reader scanned grade A with 1 finding 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 5d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
curl -sS --max-time 20 "https://api.fxtwitter.com/<user>/status/<id>" \ How it starts
The opening of the file, as written. The whole thing — 181 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Twitter Reader
Fetch Twitter/X post and article content with full media support.
Reading a single post's text: fxtwitter first (2026-08-30)
For plain post text, prefer the fxtwitter mirror API — login-free, key-free,
works direct, and returns the full note_tweet body in tweet.text (the
full_text key does not exist; a 2,324-char long-form announcement came back
complete):
curl -sS --max-time 20 "https://api.fxtwitter.com/<user>/status/<id>" \
| python3 -c "import json,sys; t=json.load(sys.stdin)['tweet']; print(t['created_at']); print(t['text'])"
replies is a count, not the reply thread. For X Articles with images, use
fetch_article.py below — fxtwitter does not carry article bodies.
Quick Start (Recommended)
For X Articles with images, use the new fetch_article.py script:
uv run --with pyyaml python scripts/fetch_article.py <article_url> [output_dir]
Example:
uv run --with pyyaml python scripts/fetch_article.py \
https://x.com/HiTw93/status/2040047268221608281 \
./Clippings
This will:
- Fetch structured data via
twitter-cli(likes, retweets, bookmarks) - Fetch content with images via
jina.aiAPI - Download all images to
attachments/YYYY-MM-DD-AUTHOR-TITLE/ - Generate complete Markdown with embedded image references
- Include YAML frontmatter with metadata
Example Output
Fetching: https://x.com/HiTw93/status/2040047268221608281

Alternative: Jina API (Text-only)
⚠️ Known reliability risk (2026-08-30 live tests): anonymous r.jina.ai
access to x.com gets 403-globally-banned for hours when third-party
users abuse the domain — the ban blocks every anonymous caller, then
expires. Verified working again after expiry (anonymous fetch then returns
post text), so treat Jina as intermittent, never a load-bearing path.
The shared key in this repo is also currently out of balance (402
InsufficientBalanceError), which makes fetch_tweets.sh — it hard-requires
JINA_API_KEY — unusable until recharged.
What ships with it
3 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.

twitter-reader is a skill published in the GitHub repository daymade/claude-code-skills (1,384 stars, last pushed today), licensed MIT. It adds 76 tokens to every session and 1,363 once invoked, about $0.0004 per session on Opus 5. A static security scan graded it A with 1 finding (makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
