## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work.
> - Agent runs need credentials for a specific provider and sign-in
method.
> - Connections already owns accounts, grants, and access permissions.
> - AI authentication should use those same boundaries.
> - This pull request adds the storage, API, adoption, and runtime
foundation.
> - Legacy agents keep their authentication until they explicitly adopt
a managed connection.
## Linked Issues or Issue Description
**Problem or motivation**
AI credentials are configured separately from Connections. Agents cannot
consistently reuse a responsible user's account or a permitted shared
account.
**Proposed solution**
Manage AI accounts with the existing Connections grants and permissions.
Keep model and harness selection independent from credential selection.
Preserve legacy authentication until validated adoption.
**Alternatives considered**
A separate credential registry would duplicate ownership and access
policy. Automatic fallback would risk using the wrong account.
**Roadmap alignment**
This extends the shipped Apps, multi-user, secrets, and agent-runtime
capabilities. The maintainer requested the feature and reviewed the UI.
Related groundwork: #11899 (connection permissions), #10910 (connection
wizard), #11692 (Claude subscription profiles), and #11854 (Codex
account rotation).
## What Changed
- Add AI-purpose/runtime-auth contracts and an additive, idempotent
migration.
- Add Claude, OpenAI, OpenRouter, and Grok provider capabilities and
catalog entries.
- Store credentials on grants. Resolve responsible-user defaults or
explicit permitted grants.
- Isolate managed credentials and provider sessions across accounts.
Block missing credentials without ambient fallback.
- Keep imported legacy secrets unchanged during reconnect. Use
independent local Codex/Grok sign-in attempts for rotating credentials.
- Add authorization, migration, concurrent refresh, retry, cancellation,
and legacy-compatibility tests.
This is part 1 of a two-PR stack. The app UI follows in #13248. Merge
the foundation first.
## Verification
- Updated against master `04e364236`, preserving upstream provider login
and connector workflows.
- Full workspace typecheck, production build, Storybook build, and token
gates passed on the integrated branch. Final local-login changes passed
59 focused tests; new-agent and inbox regression suites passed 63 tests.
- Browser checks verified automatic local Claude account detection,
resumable Codex login commands, retry, focus restoration, and
desktop/phone layouts. Commands create their isolated directory before
invoking the CLI.
- All current-head CI checks passed on `2a996560a`, including all
server/workspace tests, browser shards, runner verification, typecheck,
build, and canary dry run. Greptile reviewed that commit at 5/5 with no
unresolved threads. Earlier local full-suite attempts hit the Mac
PostgreSQL shared-memory limit; the complete suites passed in CI.
- Renumbered the additive AI migration to `0276` after upstream
migrations and regenerated its snapshot. Existing legacy agents retain
their configuration.
- Added local login status checks, owner-scoped retry, managed OpenCode
remote homes, credential-aware model discovery, and task
connection-repair delivery.
## Risks
- Managed credential failures intentionally block execution. They do not
restore legacy fallback.
- Preview-era copied Codex/Grok subscriptions require independent
reconnect.
- The integrated branch has live provider acceptance coverage. This
update verifies local Claude detection and Codex API-key task repair; it
does not add a new subscription authorization/refresh or Daytona stress
pass.
- Runtime-auth connections must stay excluded from tool and channel
handling.
## Model Used
OpenAI GPT-6 through Codex, with reasoning, repository tools, code
execution, and browser testing. The exact runtime model identifier and
context-window size are not exposed in this session.
