What it does

Claude Subscription Login is an agent skill from tamaratran/jev-pruner. Complete an explicitly authorized official Claude subscription login on a Linux Devin Docker worker without inference or credential logging.

Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. The skill folder holds 1 other file (for example `login.py`).

It sits in DevOps & Cloud, covering Containers. It works with Docker and Linux. The repository describes itself as: Claude Code plugin: trim long Bash output with TypeSafe Jev before the model sees it. The licence is MIT.

What it can do on your machine

Read from SKILL.md and the folder at commit edbc602. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships script files (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • claude
    • python

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Claude Subscription Login loads about 629 tokens when it runs. Until then it costs about 42 tokens; SKILL.md has 309 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~42
When it runs · the whole SKILL.md, loaded when a task matches
~629

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check passed

The automated check found no risky patterns in SKILL.md.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); files beside SKILL.md are not scanned.

description
Complete an explicitly authorized official Claude subscription login on a Linux Devin Docker worker without inference or credential logging.

Use only when the user requests subscription login. Authentication does not authorize a benchmark, smoke, or inference call.

  1. Use the existing Chrome browser and its CDP endpoint at http://localhost:29229. Docker must already work, and the image must contain Claude Code 2.1.274. The helper needs Python playwright and pexpect==4.9.0.

  2. Create a dedicated mode-700 auth home outside the repo and evidence. Do not read credential file contents or save an OAuth token as a Devin secret without separate permission.

  3. Run the helper with explicit parameters:

    sh
    python login.py --image "$SMOKE_IMAGE" \
      --auth-home "$CLAUDE_AUTH_HOME" --email "$LOGIN_EMAIL"

    It starts claude auth login --claudeai in a temporary container, opens the official URL, and privately submits the official one-time callback code to the CLI. It never runs claude -p. No CLI output containing codes is logged.

  4. Continue the official browser flow. Confirm the exact requested account identity in the Google UI before entering an authorized password using secure secret substitution. Pause for user verification or CAPTCHA in this Desktop. Never expose passwords or callback codes in messages/screenshots.

  5. Read the helper's output after the user completes verification. It reports Login successful only when the official CLI does. Do not infer login success from the browser alone. The helper times out after 30 minutes.

  6. Verify with claude auth status --json in a fresh container using only the private auth mount. Do not pass API keys, auth tokens, cloud-provider flags, custom headers, or an OAuth token override. Use --setting-sources '' and --settings '{"forceLoginMethod":"claudeai"}'. Report only selected status fields, not the entire config or credential contents.

  7. Confirm no benchmark containers/processes are running. Keep subsequent evaluations paused unless separately authorized. See evals/README.md for read-only mounting, private per-trial auth storage, and reporting caveats.

Verified on Linux with the official Google login, user-completed 2FA/CAPTCHA, Claude Code 2.1.274, and Max subscription status. Status is local authentication selection, not a test of model availability or remaining subscription allowance.
