What it does
Ralph is an agent skill from opentabs-dev/opentabs. Plan work and generate ralph task files for autonomous execution. Use when the user wants to plan tasks, create a prd, run ralph, or fix a batch of issues. Triggers on: ralph, create tasks, plan this, run ralph, prd.
Its SKILL.md is about 160 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files (for example `CLAUDE.md` and `__SKILL__.md`).
It sits in Product & Project Management, covering PRD writing and Browser automation. It works with Model Context Protocol, TypeScript and Chrome Extensions. The repository describes itself as: Browser automation clicks buttons. OpenTabs calls APIs. The licence is MIT.
When your agent uses it
- The user wants to plan tasks
- Fix a batch of issues
Example prompts
- “/ralph”
What it can do on your machine
Read from SKILL.md and the folder at commit de9200b. It shows what the files ask for, not the result of running them.
Tool permissions
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.
Runs code
No scripts in the folder and no shell commands in SKILL.md.
From the folder's file list and the shell code blocks in SKILL.md.
Network
No URLs in SKILL.md.
From URLs in SKILL.md, links to its own repository left out.
Credentials
Names no API keys, tokens, secrets or passwords.
From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.
Context cost
Ralph loads about 157 tokens when it runs. Until then it costs about 56 tokens; SKILL.md has 59 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.
Safety
Auto-check passed
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.
SKILL.md
