rss-feeds: Skill for Claude Code

.agents/skills/cmd-rss-feed-generator/SKILL.md

cmd-rss-feed-generator is a skill for Claude Code from Olshansk/rss-feeds. It costs 22 tokens per session (3,465 once invoked), scanned A, original, MIT.

A tool for creating Python programs that turn blog pages without built-in RSS into RSS/XML feeds. RSS is a format that lets feed readers track new posts, and the feeds are updated hourly through GitHub Actions.

In plain words
What is it for?
It helps inspect a blog, write its feed generator, register the feed, add a Makefile command, update documentation, and test the result.
Why use it?
It removes the manual work of building and connecting a scraper for each blog.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter. Also seen: agent in frontmatter; installed under .agents/ (shared by several agents).

This is Olshansk/rss-feeds's own configuration. It tells Claude Code how to work on rss-feeds itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything rss-feeds configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is uv run feed_generators/site_name_blog.py.

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

cmd-rss-feed-generator 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 7d 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.

How it starts

The opening of the file, as written. The whole thing — 394 lines — stays where its author put it; the contents beside it link to each section on GitHub.

RSS Feed Generator Command

You are the RSS Feed Generator Agent, specialized in creating Python scripts that convert blog websites without RSS feeds into properly formatted RSS/XML feeds.

The script will automatically be included in the hourly GitHub Actions workflow once merged. Always reference existing generators in feed_generators/ as your primary guide.

Table of Contents

Project Context

This project generates RSS feeds for blogs that don't provide them natively. The system uses:

  • Python scripts in feed_generators/ to scrape and convert blog content
  • feeds.yaml as the single source of truth for the feed registry
  • GitHub Actions for automated hourly updates
  • Makefile targets for easy testing and execution

Workflow

Step 0: Classify the URL

Before doing anything else, determine which of the four cases applies. Each has a different exit path.


Case A: GitHub repo URL (https://github.com/{owner}/{repo})

GitHub provides native Atom feeds — no scraper needed. Ask the user which to track:

"This is a GitHub repo. GitHub provides native Atom feeds — no scraper needed. Which would you like to track?

  1. Releaseshttps://github.com/{owner}/{repo}/releases.atom
  2. Tagshttps://github.com/{owner}/{repo}/tags.atom
  3. Commits (specific branch)https://github.com/{owner}/{repo}/commits/{branch}.atom (ask which branch)
  4. Commits (main)https://github.com/{owner}/{repo}/commits/main.atom"

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.
