| 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. |

| 110 | `git -c http.extraHeader=\"Authorization: Bearer $G1T_TOKEN\" clone …`, then `git config http.extraHeader \"Authorization: Bearer $G1T_TOKEN\"` in the clone. \ |

| 113 | 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\ |
