## Thinking Path
> - Paperclip is the open source app people use to manage AI agents for
work
> - AI connections let a user connect a Claude subscription for all
agents of an organization
> - In a Docker deployment the server runs `claude setup-token` in a PTY
and parses its output for the sign-in URL
(`server/src/services/local-ai-browser-login.ts`,
`packages/adapters/claude-local/src/server/setup-token-parse.ts`)
> - The Docker image installs `@anthropic-ai/claude-code@latest`, and
`claude` 2.1.291 adds a copy hint line between the URL and the code
prompt
> - The parser requires the prompt on the first non-blank line after the
URL, so it returns null and the UI waits without an error
> - This pull request lets the parser skip that exact hint line
> - The benefit is that Claude subscription sign-in works again with the
current CLI
## Linked Issues or Issue Description
No issue exists. I searched open and closed issues and pull requests for
"Preparing browser sign-in" and the setup-token parser.
**What happened?**
In the "Claude - Subscription" connection dialog, the UI shows
"Preparing browser sign-in…" and "Start sign-in again". It shows no
sign-in link and no error. "Start sign-in again" starts the same wait
again. After 300 s the run fails with "Sign-in ended before the account
was connected".
**Expected behavior**
The dialog shows the sign-in link and the code field a few seconds after
the start.
**Steps to reproduce**
1. Run the Docker image with `claude` 2.1.291 (`@latest` at the time of
writing).
2. Open the AI connection dialog and select "Claude - Subscription".
3. The dialog stays on "Preparing browser sign-in…".
**Paperclip version or commit**
`master` at 03cf6a6ec (includes #14970). `claude --version`: 2.1.291.
**Deployment mode**
Authenticated, private exposure, Docker.
**Relevant logs or output**
The server logs nothing for this flow. A manual run in the container
shows the output that the parser reads (URL values removed):
```
docker exec -it -u node <container> sh -c 'CLAUDE_CONFIG_DIR=$(mktemp -d) CLAUDE_CODE_OAUTH_TOKEN= ANTHROPIC_API_KEY= ANTHROPIC_AUTH_TOKEN= BROWSER=true claude setup-token'
Browser didn't open? Use the url below to sign in (c to copy)
https://claude.com/cai/oauth/authorize?code=true&client_id=…&response_type=code&redirect_uri=ht
tps%3A%2F%2Fplatform.claude.com%2Foauth%2Fcode%2Fcallback&scope=user%3Ainference&code_challenge=…
…&code_challenge_method=S256&state=…
Hold Shift while selecting to use your terminal's native copy
Paste code here if prompted >
```
`findBrowserCodePrompt` reads the first non-blank, non-URL line after
the URL. Here that line is the copy hint, so the parser returns null.
The runner never calls `onPrompt`, and `check()` returns
`sign_in_required` with no `authorizationUrl` and no error.
## What Changed
- `setup-token-parse.ts`: add `COPY_HINT_LINE_RE`, which matches only
the exact copy hint (CHA-spaced words and a curly apostrophe are
allowed). `findBrowserCodePrompt` skips a line that matches it. The
prompt line rules do not change.
- `setup-token-parse.test.ts`: add a test with the 2.1.291 layout
(hard-wrapped URL, CHA-spaced hint, blank lines, prompt).
## Verification
- `bun test
packages/adapters/claude-local/src/server/setup-token-parse.test.ts
packages/adapters/claude-local/src/server/setup-token-characterization.test.ts`:
71 pass, 1 skip, 0 fail.
- The 2.1.291 output above returns `null` before the change and the URL
plus prompt after the change.
- The test "returns null when a code-like value sits on the line after
the URL" still passes. Other prose between the URL and the prompt still
fails closed.
## Risks
- Low risk. The change skips one fixed line and binds no value from it.
- A later CLI version can change the hint text again. The flow then
hangs the same way until the 300 s timeout. An earlier error (for
example, when no prompt appears after 60 s) and a `log` option for
`runSetupTokenLogin` in `local-ai-browser-login.ts` would make this
visible. This pull request does not include them.
## Model Used
- Claude Opus 5.5 (`claude-opus-5-5`) in Claude Code, with tool use
(code search, shell, test runs). A human ran the container commands and
reviewed the change.
