The backend import package is now docsgpt, the name it will carry on PyPI; application was far too generic to install into anyone's site-packages. git mv plus a mechanical rewrite of every import, dotted string and path reference: 734 Python files, the compose files, Dockerfile, workflows, docs, setup scripts, devcontainer, k8s manifests, vscode config, pytest and coverage config, .gitignore. Behaviour is unchanged. Kept for one release: - A top-level application package whose meta-path finder resolves application.x.y to the already-imported docsgpt.x.y object, so old imports and entry points (celery -A application.app.celery, uvicorn application.asgi:asgi_app) keep working with a FutureWarning. - Celery registers every application.* task name as an alias of its docsgpt.* task on start-up, so messages queued by the previous release still run. The redbeat key prefix moves to redbeat:docsgpt:v2: so schedule entries the previous release wrote are left unread instead of firing twice. The backend image builds from the repository root (docker build -f docsgpt/Dockerfile .) so it can ship the alias package; a root .dockerignore allow-lists docsgpt/ and application/ and keeps caches, local data, .env files, the sample index files and the Dockerfile out. Compose and the image workflows point at the new context.

"""Agent YAML export / import.
|
|
|
|
Agents are mostly references (sources, tools, prompt, models). Export
|
|
translates those into portable identifiers and never emits a secret;
|
|
import resolves them back against the importing user — matching existing
|
|
resources or creating them from the file plus user-supplied tokens.
|
|
|
|
Re-import is idempotent at every level: the agent is matched by
|
|
``metadata.id`` then ``metadata.slug``, tools by ``(type, name)``,
|
|
prompts by ``(name, content)``, custom models by
|
|
``(display_name, upstream_model_id, base_url)`` — so the same file
|
|
applied twice updates rather than duplicating.
|
|
|
|
Workflow agents additionally carry their graph under ``spec.workflow``.
|
|
The graph's agent nodes reference tools, sources and models by raw id in
|
|
their config; export rewrites those into the same portable identities the
|
|
top-level sections use (``tool-N`` keys into ``spec.tools``, source names,
|
|
custom-model display names), and import resolves them back and writes the
|
|
graph through the same validation gate as the workflow API.
