Rssaurus CLI is an agent skill from majiayu000/claude-skill-registry. Use the RSSaurus command-line client (Go binary rssaurus) to interact with https://rssaurus.com from the terminal: authenticate (rssaurus auth login/whoami), list feeds/items, print item URLs for piping, open URLs, and perform triage actions (mark read/unread, bulk mark-read, save/unsave). Use when asked to automate RSSaurus tasks from CLI, debug token/config issues, or demonstrate command usage.
Its SKILL.md is about 590 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `metadata.json`).
It works with Bash. The repository describes itself as: Searchable Claude Code skills catalog with source-linked guides and generated registry artifacts. The licence is MIT.
3 steps, taken from the first numbered list in SKILL.md.
Read from SKILL.md and the folder at commit 2d14a69. It shows what the files ask for, not the result of running them.
Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.
From allowed-tools in the SKILL.md frontmatter.
No scripts in the folder and no shell commands in SKILL.md (its code samples are bash).
From the folder's file list and the shell code blocks in SKILL.md.
Hosts in commands or code, which the agent is likely to contact:
rssaurus.comAlso links to:
github.comFrom URLs in SKILL.md, links to its own repository left out.
Names these keys or tokens, usually read from environment variables:
RSSAURUS_TOKENFrom names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Rssaurus CLI loads about 587 tokens when it runs. Until then it costs about 104 tokens; SKILL.md has 109 words of instructions outside code blocks.
Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.
The automated check found no risky patterns in SKILL.md.
Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

Rssaurus CLI fits situations like: asked to automate RSSaurus tasks from CLI; debug token/config issues; demonstrate command usage.
Run `npx skills add majiayu000/claude-skill-registry --skill rssaurus-cli -a claude-code`. Or copy the skill folder (skills/bash/rssaurus in majiayu000/claude-skill-registry) into .claude/skills/rssaurus-cli in your project. Claude Code loads it when a task matches its description.
Run `npx skills add majiayu000/claude-skill-registry --skill rssaurus-cli -a codex`. Or copy the skill folder (skills/bash/rssaurus in majiayu000/claude-skill-registry) into .agents/skills/rssaurus-cli in your project. Codex loads it when a task matches its description.
Cursor, Gemini CLI, GitHub Copilot and OpenCode also load SKILL.md folders. With the skills CLI, run `npx skills add majiayu000/claude-skill-registry --skill rssaurus-cli -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/rssaurus-cli, .gemini/skills/rssaurus-cli, .github/skills/rssaurus-cli and .opencode/skills/rssaurus-cli in your project.
Going by SKILL.md and its folder, Rssaurus CLI needs credentials named RSSAURUS_TOKEN. Our summary lists: A credential in RSSAURUS_TOKEN.
SKILL.md names 2 domains. In commands or code: rssaurus.com; the agent is likely to contact it when it follows the instructions. As links in the text: github.com. This is read from the text; nothing was executed.
Our automated static check of SKILL.md found no risky patterns, such as piping downloads into a shell, reading credential files or hidden Unicode. It is not a guarantee. Review the folder before installing.
Rssaurus CLI is published under the MIT licence (the repository's licence). It allows redistribution, so the full SKILL.md is shown on this page.
About 587 tokens (SKILL.md is roughly 2.3k characters). Agents keep only the skill's name and description in context until a task matches; then they load SKILL.md in full.
