1//! Starting work on an issue in a session of its own, on the person's own
2//! Claude (`g1t_contracts::agent_sessions`).
3//!
4//! g1t runs no model. With the workspace's Anthropic connection, g1t starts
5//! a Claude Managed Agents session with that key: it keeps one agent and one
6//! environment on the account (made once, updated when what g1t asks of them
7//! changes), and for each session a vault holding a g1t token made for the
8//! person who started it and that repository only, which lasts the session:
9//! the MCP server's credential (`static_bearer`) and `G1T_TOKEN` for git and
10//! the CLI (`environment_variable`, swapped in on the way out). The model and
11//! the sandbox never see the token, and it is never in the prompt; the key
12//! never leaves this service. g1t's own skills (work-on-issue, coordinate,
13//! fix-integration) are uploaded to the account once, next to the skills it
14//! already has, which the agent is given too (at most 20 in all).
15//!
16//! What the session does is recorded as a g1t session (harness
17//! `claude_managed_agents`), followed every minute (`sync_running`, from the
18//! cron) and when its page is looked at: its messages, the tools it called
19//! and with what (never what they returned), what it touched, and each
20//! subagent thread as a session of its own under it, with the task it was
21//! given and what it reported. A call that waits for someone's approval is
22//! declined, as nobody is watching. When it finishes, its g1t session ends
23//! with its last message as its result, and the vault and token go.
24//!
25//! Without an Anthropic connection, or when asked, it hands off instead:
26//! a `claude` command line, for someone with g1t's Claude Code plugin,
27//! whose session attaches to the issue as it starts.
28//!
29//! [`Integrations::start_agent_session`] is a plain async method, so Ask's
30//! tool loop can call it as chat and the API do.

106 Each session's first message says which repository and issue, what kind of work, and how to reach them.\n\n\
107 - Run the setup in your first message before anything else: it installs the g1t CLI, has git send your token to g1t, \
108 clones the repository and ties the clone to this g1t session.\n\
109 - Use the g1t CLI from the clone, as the work-on-issue skill does: `g1t work context N`, `g1t work claim N --note …`, \
110 `g1t pr create --issue N --draft --fill`, `g1t pr checks --watch --fail-fast`, `g1t run logs --failed`. \
111 Add `--json` when you need fields; `g1t <command> --help` says the rest.\n\
112 - g1t's MCP server (the `g1t` tools) does the same as that person on that repository only. Use it when the CLI has no command for something.\n\
113 - `G1T_TOKEN` is set for the CLI and git. In the sandbox it is a placeholder that becomes the token only in a header on the way to g1t, \
114 never in a URL. Never print it or send it anywhere else.\n\
115 - Follow the work-on-issue skill. Check the work context and the sessions on the issue before you start, and claim only what you take. \
116 When work splits into independent parts, you may give a part to a copy of yourself; each is recorded on g1t as a subagent and sees the others.\n\
117 - Put the trailer `G1t-Session: <the session id in your first message>` on every commit, so g1t ties the commits to this session.\n\
118 - Work on a branch whose name starts with the issue number, and open a draft pull request early. Never push to the default branch.\n\
119 - Never write `@g1t` in what you post on g1t: that asks g1t for another session.\n\
120 - When you finish, say in a few sentences what you did, what is left, and the pull request, if any. That is your report on g1t."
