What it does
Rca is an agent skill from udecode/dotai. Turn Remote Control on for every non-archived Claude Code session in the Claude desktop app.
Its SKILL.md is about 270 tokens, which your agent loads only when the skill is triggered. It is a single SKILL.md file with no bundled scripts.
It works with Model Context Protocol.
Example prompts
- “/rca”
Workflow steps
4 steps, taken from the first numbered list in SKILL.md.
- Load the tools with ToolSearch: select:mcpccd_session_mgmtlist_sessions,mcpccd_session_mgmtget_session,mcpccd_session_mgmtset_remote_contro…

- Reply in one line: how many you turned on, how many were already on, and each session that refused with its reason. The app refuses a…
What it can do on your machine
Read from SKILL.md and the folder at commit 7d68fd7. 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
Shell commands in SKILL.md call:
claude
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
Rca loads about 274 tokens when it runs. Until then it costs about 24 tokens; SKILL.md has 136 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
Without a licence we can't republish the file, so here is its outline and opening line. It has 136 words (~274 tokens).
“Run this from a Code session in the Claude desktop app. It needs the app's session tools, which a terminal or headless claude -p session does not have.”

With the skills CLI, run `npx skills add udecode/dotai --skill rca -a cursor` (or -a gemini-cli, github-copilot or opencode for the others). To copy it by hand, put the folder in .cursor/skills/rca, .gemini/skills/rca, .github/skills/rca and .opencode/skills/rca in your project.
What does Rca need to run?
Going by SKILL.md and its folder, Rca needs the command-line tools its instructions call (claude).
