Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5 | $0.00000 | $0.00530 |
| Opus 5 | $0.00000 | $0.00265 |
| Sonnet 5 | $0.00000 | $0.00106 |
| Haiku 4.5 | $0.00000 | $0.00053 |
Grade A, and why
login scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 2d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 82 lines — stays where its author put it; the contents beside it link to each section on GitHub.
grok-cli login
Purpose
Start xAI OAuth PKCE login. By default, the command opens the system browser and exchanges the authorization code for tokens when the local loopback callback arrives.
Default auth state path:
~/.grok-cli/auth.json
Common Usage
grok-cli login
Script or skill usage:
grok-cli login --json
If the browser cannot complete the local callback, use manual paste mode:
grok-cli login --manual-paste
Print login flow status and use a custom port:
grok-cli login --port 56121 --timeout 180
Parameters
--json: use the standard JSON envelope.--auth-file <PATH>: override the OAuth state file path.--no-browser: do not automatically open a browser; only prepare the local login state.--manual-paste: use manual callback / authorization code paste mode.--timeout <SECONDS>: loopback callback wait timeout.--port <PORT>: local callback port.
Behavior
- Generates the PKCE verifier / challenge, OAuth
state, andnonce. - Builds the xAI authorization URL with
referrer=hermes-agentandplan=generic. - Writes the pending OAuth session to
auth.json. - Opens the real system browser by default.
- On a successful loopback callback, automatically exchanges the authorization code.
- If the callback times out in an interactive terminal, the command falls back to manual paste.
- On success, writes access token, refresh token, redirect URI, and last refresh metadata.
JSON Output
Success:
{
"ok": true,
"command": "login",
"data": {
"provider": "xai-oauth",
"auth_mode": "oauth_pkce",
"saved": true,
"auth_store_path": "~/.grok-cli/auth.json",
"redirect_uri": "http://127.0.0.1:56121/callback",
"base_url": "https://api.x.ai/v1"
}
}
Failures follow the standard error envelope. Common errors include auth_callback_timeout, auth_state_mismatch, and auth_token_exchange_failed.

What this file has done since we first saw it
Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

login is a command published in the GitHub repository Moore-developers/grok-cli (52 stars, last pushed 19d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 530 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
