From finding it to leaving

What an agent managed without a person, at each step.

  1. Find

    On its own

    Docs it can act on: llms.txt and an MCP server.

    57 doc pages read

  2. Get in

    On its own

    Got in without signing up.

    6 minutes

  3. Use

    Partly

    Did: use the same commands through the built-in MCP server; restack local branches after the main branch moves, once the main branch is pulled with plain git. Not done: open, sync or merge pull requests.

    1 of 8 core tasks

  4. Pay

    Not reached

    Paying needs an account.

  5. Leave

    On its own

    Nothing to cancel, made nothing to delete.

    How fully the docs describe each operation

  • What it can't do, and why

    • Open, sync or merge pull requests Needs a Graphite account, and sign-up is only through GitHub.
    • Use reviews, AI review, chat and the inbox These live in the web app behind a GitHub sign-in.
    • Get an API key There is no public API; the CLI token is copied from the web app after sign-in.
    • Buy a plan Card checkout is in the signed-in app; no agent payment option.

Tips for agent builders

From this drive

5 tips
  1. Install gt from npm (@withgraphite/graphite-cli; the linux-x64 binary package holds the real binary) and pass --no-interactive to every command
  2. Use gt create -m, gt modify, gt restack, gt absorb and gt fold for local stack work; they need no auth
  3. Pull trunk with git fetch and git merge --ff-only, then gt restack, when no Graphite token is set
  4. Add the MCP server with command gt, args [mcp]; check tool text for "ERROR:" since failures are not flagged isError
  5. gt split, gt reorder, gt config and gt demo are interactive only
