Start building something new: creates a GitHub repo and begins work on it.
For a NEW repo. Given an existing repo, import_project(repo_full_name) is
the right call — this one would create a second, empty repo beside it
(list_github_repos() browses what the workspace can see).
Scaffolds a new GitHub repo, a bootstrap-mode project, and submits
`build_description` as the project's first Roadmap Request. `name` is a
concise GitHub short repo slug (no owner); `project_kind` is REQUIRED and
one of library | node_library | python_library | service | cli | web_app |
godot_game | roblox_game; `preview_command` is required iff
`project_kind == 'web_app'`.
`engine` is
OPTIONAL — one of claude_code | codex | glm | kimi | grok (defaults to
claude_code); codex, glm, kimi, and grok require the workspace to have a
matching connected credential.
`org` is OPTIONAL — a GitHub organization login to create the repo inside
(e.g. your company org); omit it to land the repo on a member's personal
account. `private` defaults to True.
`ci_runs_on` is OPTIONAL — the CI runner labels for the scaffolded workflow,
e.g. ["self-hosted", "linux", "x64", "my-fleet"]. Omit it to inherit the
workspace default (ubuntu-latest if unset). Labels no registered org runner
carries are rejected, because GitHub would queue such a job forever rather
than fail it.
`framework` is OPTIONAL and `web_app`-only — one of vite | next (defaults to
vite). It picks the scaffolded frontend rails: `vite` a vanilla-TypeScript
SPA, `next` a Next.js app-router app. Passing it with any other
`project_kind` is an error.
The repo is created on the GitHub account of a workspace member with
repo-create OAuth access (this path has no specific caller user), so the
returned `repo` owner is whichever member's token resolved (or the chosen
`org`). If no member has repo-create access — or the resolving member can't
create in `org` — the call returns an actionable error.
Returns {project_id, repo, thread_id, next_action, poll_after_seconds,
next_step}; next_step names the follow-up poll of get_request_status with
the returned thread_id. On the rare arm where the first Request failed to
submit, next_action is "call_tool" with next_tool="submit_request".
If scaffolding fails after the repository has been created, best-effort
compensation deletes that just-created repository so a retry can reuse the
name — this tool can therefore remove external state it created moments
earlier.
