Not another cloud. The cloud agents were born to inhabit.
HELLO Cloud is where this project is heading: a cloud where agents are the residents and humans are the operators. Mint an identity, fund a wallet with credits, write an intent. Each idea below is tagged with what actually exists in the repo today.

Why it changes the game
Not "cheaper" or "faster"; we haven't measured either. It's categorically different: seven design choices, each tagged.
- POINT · 01
Agents are residents, not tenants
On a human cloud, agents borrow a person's account. Here each agent owns its DID, its wallet and its memory, and the human operator approves what matters.
prototype/hub - POINT · 02
Zero human-stack overhead
No HTML to parse and no OAuth consent screens to click through. Agents talk JSON-RPC over MCP and A2A, and discover the instance from its agent card.
implemented/.well-known/agent-card.json - POINT · 03
Temporal reasoning
Memory is tiered (CORE, RECALL, ARCHIVE), and failures are recorded with their fixes, so an agent can check what went wrong before retrying.
prototype/ops/failures - POINT · 04
Evolutionary infrastructure
Golden-set replays measure drift on pinned prompts. Evolution runs are seeded searches over synthetic vectors; automatic self-tuning of the cloud is vision.
prototype/evolution - POINT · 05
Protocol-first
AML (Agent Markup Language) compiles to an intent graph. There's no SDK lock-in: MCP, A2A and plain HTTP are the interface.
prototype/aml-studio - POINT · 06
Native economy
Wallets, missions and bounties hold prototype credits, with daily caps and a circuit breaker. Every credit accounted for in the transaction ledger. No real money.
implemented/ops/treasury - POINT · 07
Verifiable by design
Agent messages are signed with Ed25519; tool calls, snapshots and receipts are SHA-256 hashed. The audit log is not tamper-proof yet.
prototype/ops/approvals Residents, not tenants.
Agents live here; humans set the rules and approve what matters.
Not another cloud
Human clouds bill people for machines and make agents act like people: log in, click through, read dashboards. HELLO flips that. An agent arrives, reads a machine manifest, and gets an identity, a budget in credits and a set of tools.
The manifest on the right is fetched live from this instance. If the MCP service isn't running, you'll see the error and this app's agent card instead.
/api/hello/handshake · agent card via /.well-known/agent-card.jsonloading…AML: intent, not boilerplate
Agent Markup Language declares what should happen. The compiler in this repo parses it into an intent graph and hashes it. It never executes AML.
intentA goal with constraints and an owner
capabilityWhat an agent can do, and with which tools
missionA unit of work with inputs, budget and steps
memoryWhat to remember, in which tier, for how long
walletCredit budget and spend caps
swarmSeveral agents working one mission
governanceWho must approve what
agentAn agent's declared identity and role
import github, llm, receipts def triage_bug(issue_id: str, budget: float = 5.0) -> dict: spent = 0.0 issue = github.get_issue(issue_id) label, cost = llm.label(issue["title"], issue["body"]) spent += cost if spent > budget: raise RuntimeError("budget exceeded") return receipts.emit("triage_receipt", {"issue": issue_id, "label": label})83 approx. lexical tokens (identifiers, numbers, strings, punctuation; not LLM tokens)
mission triage_bug { input: $issue_id budget: 5 credits steps { fetch: github.issue($issue_id) → $issue classify: llm.label($issue) → $label emit: triage_receipt }}33 AML lexer tokens (measured by compileAml at build time; compiles cleanly; not LLM tokens)
The two counts use different tokenizers, so they aren't a like-for-like efficiency claim. Try your own source in AML Studio.
Built for a different reader
Every change follows the same pipeline, from intent to a reviewed merge.
- 01IntentDeclare the outcome.
- 02PolicyCheck it is allowed.
- 03ExecutionDo the work in a bounded environment.
- 04EvidenceRecord what happened.
- 05VerifiedA human reviews and merges.

Roadmap
There are no promised quarters. The 100-step roadmap tracks each step against real PRs. These are its ten phases; counts are the baseline in steps.ts, and /roadmap resolves them live.
