Four things every team shipping with agents needs.

Solo builders and engineering teams keep reaching for the same four primitives. Arca ships them as one harness so the agents, the people, and the work stay in sync.

01

Persistence

One vault holds the project, the agents, and the documents. Sessions end; state stays. No work lost between runs.

02

Governance

Constitutions per manager, provider fences, claim tokens, and an append-only ledger.

03

Agent management

Spawn, name, and retire managers and workers from one canvas. Each one keeps its role.

04

Observability

Every frame, claim, and outcome is written to a timeline you can replay. See what an agent did, why, and when.

FIG 1.0 Persistence →

Your project, agents, and documents in one vault.

Sessions end; state stays. Arca writes every agent, prompt, and document into a local-first vault you own, so a builder picks up tomorrow exactly where the agents left off tonight.

Give your agents infinite, structured recall with Graphify.

Agents are only as good as their context. Graphify automatically builds a semantic graph from every conversation, document, and PR, giving your fleet instant access to the entire history of your workspace.

Identify the database schema constraint that caused the production rollout of auth-service to fail during the 14:00 UTC deploy window yesterday, and list any active workers that committed code to that branch within 3 hours prior.
👑Program Manager

During yesterday's 14:00 UTC deployment, auth-service crashed due to constraint conflicts from Migration #842 (duplicate key on user_profiles.email).

Filtering active commits 3 hours prior (11:00–14:00 UTC), I identified that **Worker arca-4** committed the validation schema patch at 12:45 UTC, causing the rollback lock.

FIG 2.0 Agent management →

Spawn agents in role. Keep them in role.

Every agent has a named manager constitution that holds its role, prompt, and history. Solo builders run the full set themselves; teams assign disciplines per agent. Replies land in the same ledger, never a side channel.

Humans and agents on the same board.

Engineers take the judgement calls; agents take the well-shaped work. Drag a card to Review and the agents replan. The handoff stays legible and the queue stays one queue.

FIG 4.0 Governance →

Agents act inside the lines you set.

Constitutions, provider fences, claim tokens, cross-workspace fences, and an append-only ledger. Solo builders set the policy themselves; teams roll it out once and audit centrally.

What agents can initiate without losing operator review. What the solo fleet can do before it asks the builder.
Normal mode Solo quiet mode
⌁ Rebuild Autopilot
on-request quiet-mode

Arcatect can propose rebuilds; operator approves before restart. Arcatect can re-scope marketing work and queue workers without waking the builder.

● Worker Runtime
3 running 6 agents

Running, blocked, and finished workers stay visible to the operator. Every manager, worker, and verifier stays visible in the solo fleet.

◇ Spawn Approval Gate
planned domain only

Future [SPAWN] directives surface as approval cards before launch. Only domain, billing, and production cutover decisions interrupt the operator.

Worker Policy
Spawn roots, protected paths, launcher allowlist, and sandbox mode. Quiet-mode roots, protected secrets, deploy gates, and auto-replay.
