Pick any line to see why it is the way it is: the commit, the pull request and issue it came from, and what the agent was thinking.

Issues and pull requests replace intents and attempts1//! Runs a coding agent on one pull request and reports back to g1t.
Account dropdown, llms.txt onboarding, hosted agent runner (not yet deployed)2//!
Issues and pull requests replace intents and attempts3//! This is the program a hosted sandbox starts. It clones the pull
4//! request's fork, runs the agent harness headless, streams what the agent
5//! does into the pull request's session as it happens, pushes the result
6//! and marks the pull request ready for review. It talks to g1t only through the public API and git, exactly
Account dropdown, llms.txt onboarding, hosted agent runner (not yet deployed)7//! as an agent on someone's own machine would.
8//!
Agents as a team: lifecycle, merge queue, billing and a new shell9//! `MODE` selects another job instead: `checks` runs acceptance checks,
10//! `update` brings a pull request up to date with its target branch,
11//! `review` has an agent review one, and `revise` sends the author back to
12//! address what the checks or a review found, `plan` turns an outcome
Agents and memory, checks and conflicts, profiles, slug renames, custom domains13//! into issues, `queue` builds and checks a state of the merge queue,
14//! `mergecheck` finds out whether a pull request merges cleanly, and
GitHub Actions on g1t, part two: running workflows15//! `actions` runs one job of a GitHub Actions workflow.
Agents as a team: lifecycle, merge queue, billing and a new shell16//! See the modules of those names.
Acceptance checks in sandboxes, line comments and review verdicts17//!
Account dropdown, llms.txt onboarding, hosted agent runner (not yet deployed)18//! Configuration comes from the environment:
19//!
20//! - `G1T_API`, `G1T_TOKEN`, `G1T_USER`: where and who to report as.
Issues and pull requests replace intents and attempts21//! - `G1T_REPO`, `PULL_NUMBER`, `GIT_REMOTE`: the pull request and its fork.
Account dropdown, llms.txt onboarding, hosted agent runner (not yet deployed)22//! - `PROMPT`: what the agent is asked to do.
23//! - `COMMIT_MESSAGE`: used if the agent leaves changes uncommitted.
24//! - `ANTHROPIC_API_KEY`: read by the harness itself.
Invite-only launch: sign in with GitHub, repository access and lifecycle, many emails, a new look25//!
26//! Every mode runs with the mining watch in `abuse`: a sandbox that looks
27//! like it is mining stops itself and exits with `abuse::EXIT_CODE`.
