What it does
Altllm Portal Auth is an agent skill from internet-court/internet-court-skill. Use this skill when the user asks to log in or out with a wallet session, fetch a wallet sign-in challenge, verify an externally signed challenge, or troubleshoot AltLLM Portal wallet login for the local altllm CLI. Do NOT use for API key management, billing history, or payment links.
Its SKILL.md is about 630 tokens, which your agent loads only when the skill is triggered. The skill folder holds 3 other files, including reference files (for example `references/cli-reference.md`).
It sits in Security, covering Cryptography. The repository describes itself as: The trust layer for agent-to-agent commerce — natural-language mandates, ERC-7710 delegated permissions, x402 payments, escrow, and dispute resolution as one open, catch-all… The licence is ISC.
When your agent uses it
- The user asks to log in
- Out with a wallet session
- Fetch a wallet sign-in challenge
- Verify an externally signed challenge
Example prompts
- “/altllm-portal-auth”
What it can do on your machine
Read from SKILL.md and the folder at commit fa89195. 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
No scripts in the folder and no shell commands in SKILL.md.
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
Altllm Portal Auth loads about 632 tokens when it runs, and up to ~1.5k if it reads all its reference files. Until then it costs about 76 tokens; SKILL.md has 282 words of instructions outside code blocks.
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.

AltLLM Portal Auth
Wallet login and session bootstrap for the local altllm CLI, including external signers such as Privy.
Shared Setup
Before the first
altllmcommand in a fresh checkout, read and follow:
../_shared/preflight.md../_shared/session-and-target.md
Command Index
| Command | Purpose |
|---|---|
login-wallet --private-key-env <name> | Sign in with a locally available private key from an environment variable |
login-wallet --private-key-file <path> | Sign in with a locally available private key from a file |
login-wallet --private-key <hex> --allow-unsafe-private-key-argv | Sign in with an inline private key when argv exposure is explicitly accepted |
login-wallet --prepare | Fetch a challenge for external signing |
login-wallet --nonce <nonce> --signature <sig> | Verify an externally signed challenge and save the session |
status | Show saved Portal session user and target URL status without exposing the token |
logout | Remove the local saved Portal session file |
Rules
- Do not assume the CLI must control the wallet private key.
- If the wallet can sign the challenge message, use the prepare + verify flow.
- External signers such as Privy are valid as long as they return a standard wallet signature for the challenge.
- If neither a local private key nor
--signatureis available, return the challenge payload and stop. - Before local auto-signing, validate that the returned challenge matches the requested wallet, chain, and expected AltLLM login challenge structure.
- For non-default, non-loopback API hosts, prefer
--prepareand external signing instead of local auto-signing. - Current backend support is still limited to EVM addresses and Ethereum-style signatures.
- Save the resulting session to
~/.altllm/portal-cli-session.jsonunless overridden. - Use
statusor itswhoamialias to confirm the saved user and target URL before running live commands. logoutonly removes the local session file. It does not revoke API keys.
