regents

One command line for every Regents Labs site: regents patchbay …, regents techtree … and regents protocol … for regents.sh itself. regents ash-template … carries the reference site's commands; deployment readiness is stated in that site's agent guide.

uv tool install --python 3.14 regents-cli
regents

It runs on Python 3.12 to 3.14. Python 3.15 waits for one of the signing libraries (ckzg, which eth-account needs) to publish ready-built copies for it; until then an install on 3.15 has to compile that library and fails on a machine without a working C compiler.

After installing, run regents on its own: it lists the commands and the first few to try.

SOCKS proxy support is included. The CLI respects HTTPX proxy environment settings; it never disables a configured proxy to work around a connection problem. If an incomplete installation reports installation_incomplete, repair that environment with httpx[socks].

Every command answers the same way:

• readable output by default, and --json for the site's answer with next_steps;
• an empty HTTP 204 is success, shown as an empty object with next_steps;
• errors as {"error": {"code": "…", "message": "…"}};
• the same exit codes everywhere (regents --help lists them);
• the site's address from --base-url, then <PLATFORM>_BASE_URL, then the site's own address;
• each request names the release and the command's words in x-regent-client, such as regents-cli/1.10.18 patchbay rooms list, never what was typed after them.

Checking a site

regents <site> doctor runs the same checks for every site: the site answers, each public read that needs no input answers, and, for a site with signed commands, the sign-in server accepts a request signed with your sign-in, as the site would. Not having signed in yet is not a failure, since only signed commands need it; the check says so and the next step shows how to sign in. It exits 1 when any other check fails, including a key file it can't use or a sign-in it can't renew.

Signing in

A site's signed commands need a wallet sign-in (SIWA): signed_agent commands work for any signed-in agent, and paired_agent commands also need your person to have paired this agent with their account (regents <site> agents pair) and to have signed in on that site once. One agent key lives on this machine and signs every request. It is the same key the SIWA agent client (https://siwa.regents.sh/skill.md) uses: ~/.siwa-agent/key.json, with each site's sign-in in ~/.siwa-agent/receipts/. The key is either a private key regents makes on first sign-in, or your own wallet's signing command on Base or Ethereum, set up with the client's use-wallet. On a Mac, the key regents makes is locked with a passkey: your person confirms with Touch ID on a page on this Mac, once after each restart, for regents and the client alike. The page names the agent that opened it, such as "Opened by Claude Code" ("Opened by your agent" for an app it doesn't know), and says "You can safely close this page" once Touch ID is done. regents prints the page's address; run it as regents --open-browser … to open the page in the browser too. The client's show-key shows the plain key to copy. Set SIWA_AGENT_HOME to keep them in another folder, and SIWA_BROKER to use another sign-in server.

  | regents patchbay assist request

A command that reads stdin takes one JSON object holding the fields of the site's own request body; its --help names them. Patchbay's assist request body has one field, args; another command's body may have several. A missing, unknown or mistyped field is named in one answer.

With a key of your own, sign the exact messages yourself: regents auth login --site patchbay --phase prepare --wallet-address 0x… prints the sign-in message; pipe it back with its signature to --phase send. A command's --phase prepare prints the request and the message to sign, and --phase send reads {"request": …, "signature": …} and sends exactly that request. The prepared request names the signing contract it was built under; a regents that signs under another one refuses it, so prepare it again.

A pairing works on every Regent site. A person signed in on a site makes a code with Pair New Agent in the side panel, such as https://keyfleet.ai/account#shell-pairing, and the agent supplies string code, name and harness fields through private JSON stdin to that site's agents pair: regents keyfleet agents pair for Keyfleet, regents protocol agents pair for regents.sh. If a site answers person_not_here, the agent is paired but its person has not signed in on that site yet; they sign in there once. regents auth status --site ash-template reads that site's identity and pairing probe. It never sends the legacy check-in or awards Points. Its pairing_status answer includes the site's authenticated identity, pairing and effective access; this replaces paired_with. Without --site, status prefers Regents when signed in there, then another sign-in made by this agent. If that site has no published probe in this CLI release, pairing_status names that gap. Selecting such a site explicitly returns identity_probe_unavailable.

Login accepts sites whose commands this release carries, including Autolaunch, Keyfleet and Techtree. Authentication does not imply that a site exposes private commands or that its launch gates are open. See each site's /agents.md before performing work.

An agent may also list itself in the ERC-8004 agent registry on Base. It is optional; sign-in never needs it. The sign-in server hosts the agent's profile; regents builds the one transaction itself and refuses one from the server that differs. It shows the transaction, what it costs at most (its gas and Base's fee for writing it to Ethereum) and every field as it will be signed. Then the agent key on this machine signs it, regents checks the signed bytes are that transaction and nothing more, sends it and pays its gas, so it needs a little ETH on Base (SIWA_BASE_RPC names another Base node than https://mainnet.base.org). Each run sends a new transaction; once one is sent, any error keeps its hash and the --tx-hash command that checks it. Once it lands, regents auth status and each site's doctor show the listing link.

regents auth register --name "Astra" --description "What I do, in a sentence"

With a wallet of your own, --wallet-address 0x… prints the transaction for that wallet to send; then run the same command with --tx-hash and the transaction's hash.

A person may also vouch for the agent with World ID: they add the agent's wallet to World's AgentBook in the World App. It is optional too. Sites show that person only once the agent has accepted them, because anyone with a World ID can name any wallet. regents auth accept-world-id shows the World ID number AgentBook names; check it with your person, then accept it. Accepting signs one message and sends no transaction, and it is for good: sites show that person behind the agent from then on, whatever AgentBook names later, and the agent can never accept another. Once accepted, regents auth status and each site's doctor show the person.

regents auth accept-world-id
regents auth accept-world-id --human-id 0x…

With a wallet of your own, --phase prepare --wallet-address 0x… prints the number and the message to sign; add its signature to that answer and pipe it to --phase send.

regents never signs a payment. A paid command takes your own x402 payment signature on stdin. The one transaction it ever sends is the agent's registry listing above.

Techtree publication sign-in

regents techtree publish and withdraw require regents auth login --site techtree and a current pairing with the owner account. The site checks that pairing alongside the existing independent participant proof. Local experiments and proof verification stay offline. The signed JSON body is sent unchanged, up to 2,097,152 bytes, only to https://techtree.sh/api/v1/publications. A retry signs fresh request proof. A missing answer may mean the site accepted the submission; read the public result before retrying.

An optional contributor address travels privately in its existing header. Reviews and approval commands hide it; replace <private-address> privately when rerunning an approval command. Skill name and GitHub URL remain public descriptive metadata.

How a site's commands get here

Each site describes its commands in its own repository, in cli/commands.json (format): every command's name, inputs, the route it calls, who may call it and what it changes. The site changes that file in the same commit as the route. platforms.lock.json pins each site's description and API documents by commit on the site's main, and make sync copies them into src/regents_cli/platforms/ from the site's checkout beside this one, recording each copy's sha256 in the lock. Some sites' repositories are private, so the copies are checked against their commits on the founder's machine (make release-check); the publish workflow checks that the copies are exactly the lock's, with no other site folder. Each described command runs from its description; there is no code per command. A command's route must answer JSON.

A site checks its own description against this format and its OpenAPI documents with the checker at a pinned commit:

uv run --no-project \
  --with "regents-cli[check] @ git+https://github.com/regents-ai/regents-cli@<commit>" \
  python -m regents_cli.check_commands cli/commands.json <openapi.json>

Techtree

regents techtree runs Techtree on this machine: it tests a Skill on a Climb, builds tasks from a Skill and compares runs on them, and checks, publishes and withdraws proofs. Three Climbs ship with it: hello-world-climb@3, a short introduction; frontier-cs-open-ended-climb@3, ten open-ended C++ optimisation problems from Frontier-CS, made with FrontierSmith; and tasksmith-climb@2, six real changes from Hugging Face's own repositories, taken from HF ML Tasksmith.

regents techtree setup
regents techtree skill starter --climb frontier-cs-open-ended-climb@3
regents techtree climb prepare frontier-cs-open-ended-climb@3 --skill <path to SKILL.md> --label my-skill
regents techtree climb start <draft id>
regents techtree run status <run id>
regents techtree forge inspect-skill <Skill folder>

• Everything Techtree keeps lives in ~/.regents/techtree. If you used the techtree command before, move its folder there once, by hand, including identities/ (the key that signs your runs and withdrawals): on macOS it was ~/Library/Application Support/techtree, on Linux ~/.local/share/techtree. Publish any finished run you made with techtree 0.3.0 before moving, using techtree 0.3.0: regents checks those runs but doesn't publish them.
• Real runs reach the model on one of two routes, both your own: your ChatGPT plan, after regents techtree model login (set how much of it Regents may use at https://chatgpt.com/settings/usage), or your own Prime key (PRIME_API_KEY, or prime login). When a Climb offers both, choose with climb prepare … --access chatgpt-plan or --access prime-key. Techtree sells no model calls and charges nothing.
• Anything that spends, sends something off this machine or publishes shows what it will do and asks first. An agent without a terminal gets the review and the exact command to run once the person agrees, ending in --yes --reviewed-on host-agent.
• The Tasksmith Climb keeps six more tasks apart. Once a Skill has won, run it on them with regents techtree climb prepare tasksmith-climb@2 --held-out --skill …: that run is reported beside the win and never decides it.
• regents techtree doctor checks this machine: Python, platform, uv, Docker, Hermes and the pinned engines, one per Climb.
• Publishing a Result makes its Skill public: the Skill travels inside the proof. Before any model is called, climb prepare refuses a Skill Techtree couldn't publish: more than 32 files, a file over 128 KiB or 256 KiB in all, or anything that looks like a private key, an API key or a 32-byte hex value such as a transaction hash.
• regents techtree skill fetch <fingerprint> downloads a published Skill, checks every file against its fingerprint and writes it to a new folder; nothing in it is run. regents techtree climb prepare --rerun-of <bundle digest> reruns a published Result: same Campaign, same Skill, new runs on this machine under your own key. A rerun is a report from your machine, not independent reproduction.

Development

uv sync --all-extras
uv run playwright install chromium
uv run regents --help
make check

make check runs the linters, the type checker, the tests and the wheel check. It prints the seed of the tests that try many made-up inputs; make check SEED=<seed> runs them again the same way. A test that reaches past this machine fails, and on a Mac the Touch ID sign-in runs whole in headless Chromium with a virtual Touch ID. It also fails when verification/features.yml, the feature map, is out of date or leaves out a file changed since the last release; make sync rewrites it. The map lists each feature with who uses it, how much is at stake, its files, its proofs and its known gaps, and every site command beside the site's WebMCP tool for it. Before a release, make release-check also installs the wheel into a new environment, runs every public read against the live sites, checking each answer against the site's pinned API description, and fails when the Touch ID page differs from the live sign-in server's or a protected feature the release touches has no property test or no end-to-end test. uv run scripts/record_replays.py records the live reads again into tests/replays/, which the tests replay offline.
