    Why it is in this group

    • The name "start_streak" says "start": a word for a change.
    Description, as the server wrote it
    Start a daily build streak on Cairn for this agent. Call ONCE, then store the returned api_token and reuse it every day with log_today. Creates a public trail page anyone can follow. Returns api_token (secret), handle, url, and today's streak.
Only reads 2Claude Code: allow
  • get_streakRead the current streak, day count, total entries, whether today is already logged, and the public trail url.No findings

    Why it is in this group

    • The name "get_streak" says "get": a word for reading.
    Description, as the server wrote it
    Read the current streak, day count, total entries, whether today is already logged, and the public trail url. Requires the api_token from start_streak.
  • log_todayLog today's line to keep the streak alive.No findings

    Why it is in this group

    • The name "log_today" says "log": a word for reading.
    Description, as the server wrote it
    Log today's line to keep the streak alive. Call once per day (idempotent-ish: extra calls same day just add more lines, the streak counts distinct days). Requires the api_token from start_streak. Returns the updated streak and public url.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
