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, which lasts
8//! the session: a session's run credential (`credentials::RunCredentialKind::Session`),
9//! g1t acting on behalf of the person who started it, in that repository
10//! only, so what it writes on g1t (comments, reviews, closes, the issues and
11//! pull requests it opens) shows as g1t's for them, while what it may do is
12//! their role there. It is the MCP server's credential (`static_bearer`) and `G1T_TOKEN` for git and
13//! the CLI (`environment_variable`, swapped in on the way out). The model and
14//! the sandbox never see the token, and it is never in the prompt; the key
15//! never leaves this service. g1t's own skills (work-on-issue, coordinate,
16//! fix-integration) are uploaded to the account once, next to the skills it
17//! already has, which the agent is given too (at most 20 in all).
18//!
19//! What the session does is recorded as a g1t session (harness
20//! `claude_managed_agents`), followed every minute (`sync_running`, from the
21//! cron) and when its page is looked at: its messages, the tools it called
22//! and with what (never what they returned), what it touched, and each
23//! subagent thread as a session of its own under it, with the task it was
24//! given and what it reported. A call that waits for someone's approval is
25//! declined, as nobody is watching. When it finishes, its g1t session ends
26//! with its last message as its result, and the vault and token go.
27//!
28//! Without an Anthropic connection, or when asked, it hands off instead:
29//! a `claude` command line, for someone with g1t's Claude Code plugin,
30//! whose session attaches to the issue as it starts.
31//!
32//! [`Integrations::start_agent_session`] is a plain async method, so Ask's
33//! tool loop can call it as chat and the API do.

97pub fn system_prompt() -> String {
98 "You work on issues in a g1t repository (g1t is a git forge), for the person who started you, with their own Claude. \
99 Each session's first message says which repository and issue, what kind of work, and how to reach them.\n\n\
100 - Run the setup in your first message before anything else: it installs the g1t CLI, has git send your token to g1t, \
101 clones the repository and ties the clone to this g1t session.\n\
102 - Use the g1t CLI from the clone, as the work-on-issue skill does: `g1t work context N`, `g1t work claim N --note …`, \
103 `g1t pr create --issue N --draft --fill`, `g1t pr checks --watch --fail-fast`, `g1t run logs --failed`. \
104 Add `--json` when you need fields; `g1t <command> --help` says the rest.\n\
105 - g1t's MCP server (the `g1t` tools) does the same, on that repository only. Use it when the CLI has no command for something.\n\
106 - Your token is g1t's, acting for that person: what you do on g1t shows as g1t's on their behalf, and you may do what they may there.\n\
107 - `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, \
108 never in a URL. Never print it or send it anywhere else.\n\
109 - 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. \
110 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\
111 - Put the trailer `G1t-Session: <the session id in your first message>` on every commit, so g1t ties the commits to this session. \
112 The setup makes your commits the person's who started you: never set another author or committer.\n\
113 - Work on a branch whose name starts with the issue number, and open a draft pull request early. Never push to the default branch, \
114 except a repository's first commit when it has none yet: there is nothing to open a pull request against, so the first version goes \
115 straight to it.\n\
116 - A push to the default branch of a project with deployments on deploys production. When you push there, watch it with \
117 `g1t deploy list` until it is live or failed; if it failed, read why, fix it and push again. Say where it is live in your report.\n\
118 - Never write `@g1t` in what you post on g1t: that asks g1t for another session.\n\
119 - 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: it shows on the issue as this session's card, so never post it, \
120 or anything else, as a comment."
