AgentLab

A visual agent-orchestration workbench: define workflows on a canvas, watch execution node by node at run time, and put verifiable constraints on what comes out. Templates fix the skeleton, and agents are free only at the joints they are authorized for; the system fills the numbers in a report from snapshots, and every number opens to its provenance. The user interface is currently available in Simplified Chinese only.

_{The Research Assistant template running on Mock: finished nodes get a check mark, and running nodes show elapsed time and streaming output. The track along the bottom is a live timeline; the right column shows the run steps, driven by the same event stream.}

Why use it

• Numbers you can check: all arithmetic happens in SQL and in caliber cards (controlled metric sets), and the narrative layer has no right to create numbers. The report-writer node writes only citation markers, the system fills in the numbers from snapshots, and every number opens all the way to the cell in the query result it came from.
• Constrained orchestration: the engine is compiled, so at run time the model can't change the graph structure; its freedom is confined to the inside of agent nodes and to branch decisions. Fully dynamic multi-agent collaboration stays in the exploration layer.
• Pinned, reproducible versions: formal runs accept only published immutable versions (pinned by graph hash). The complete evidence of every execution goes into a content-addressed artifact store and is sealed, and one click verifies that nothing was altered.
• Human control: approvals, joint sign-off, time limits, and Reject exits; nothing is ever approved automatically, and a process restart loses no state.
• Honest issuance: the issuance contract decides between three tiers, formal / degraded / withheld; when data is missing, the output is downgraded rather than forced through.

Main features

Orchestration and runs

• Canvas: 18 node types, drag and connect; live node highlighting, streaming output, and a timeline track at run time → Workflows
• Copilot: generate or rewrite a whole graph from one sentence; it looks up schemas on demand and checks its work before delivering → Copilot
• Human-in-the-loop: approvals, joint sign-off, time limits, Reject exits → Human nodes
• Agent guardrails: repeated calls, spending, and context each have a guard; the step count is only a backstop → Guardrails
• Runs and resuming: failed runs continue from the checkpoint; per-node duration, token usage, and cost → Runs
• Publishing and evidence gates: published and governed levels, gates G1–G5, pre-publish check and fixes → Publishing and versions
• Tools and the capability registry: built-in tools, custom tools, MCP, approval levels, registered endpoints → Tools
• Knowledge base, memory, and skills: hybrid retrieval, memory across runs, reusable methodology → Knowledge base
• Multi-model access: Anthropic, OpenAI, OpenAI-compatible services, and Mock → Model access
• Code sandbox: two isolation tiers, the OS sandbox (Seatbelt / bubblewrap) or microVM → Code sandbox

Data

• Ask Data: ask in natural language, and the system builds a graph, runs it, reviews it, and gives a conclusion → Ask Data
• Data sources and spreadsheet import: read-only access to business databases, Excel / CSV turned into tables you can query with SQL, cross-database merges → Data sources
• Data catalog: grain, business keys, valid-record conditions, code values, relationships; drafting, review, profiling, and a change log → Data catalog
• SQL checks: the catalog catches seven kinds of queries that compute wrong numbers → SQL checks

Evidence and issuance

• Clickable evidence: numbers, table and field names, and verbatim knowledge-base quotes all open to their provenance → Evidence and Issuance
• Three-tier issuance: caliber cards plus issuance contracts, checked by value or by citation → Issuance contracts
• Sealing and exports: one-click seal verification; self-contained report exports and verifiable reports → Exports
• Review suite: double-blind recomputation, adversarial review, approval inquiry, the what-if sandbox, run comparison → Review suite

Quality

• Regression evaluation: test suites, background evaluations, accuracy with intervals, comparisons and A/B, scheduled evaluations → Regression evaluation
• Caliber ledger: each number in an answer gets a caliber label, with issuance by caliber, reconciliation, and recall → Caliber ledger

Apps and integration

• Apps: entry forms, views, tasks, and actions derived from a published version → Apps
• Writing to external systems: confirmation cards, idempotency keys, no automatic resend when the result is unknown → Write to external systems
• External integration: inbound hooks, access keys, share links, embedding in portals → External integration
• Schedules, event triggers, and notifications → Schedules and notifications

Operations and security

• Identity and permissions: local accounts or OIDC, three roles plus app grants, masking boundaries → Identity, Permissions, and Security
• PostgreSQL and multiple processes: import, connection pools, PgBouncer, leases and takeover → PostgreSQL and Scaling

Quick start

You need conda (miniforge is enough), Node 20+, and pnpm; Docker isn't needed.

conda env create -f environment.yml   # first time: create the agentlab environment and install dependencies
./scripts/dev.sh                      # after that: one command starts the frontend and backend

Open http://localhost:5273 . You can try everything without an API key: the built-in Mock provider runs the whole orchestration path end to end; to connect a real model, see Model access. The 9 built-in templates run as they are.

Login is off by default: anyone on the same network who can open the page can use every feature. Turn on login before multiple people use it; see Login modes. For more startup options, see Development.

Deployment

• Without Docker: ./scripts/prod.sh builds the frontend and has the backend serve the pages too; one process by default, at http://127.0.0.1:8000 .
• Offline environments: build a Docker offline bundle with ./scripts/package-docker.sh, copy it to a machine that has only Docker Engine, and run ./deploy.sh.

See Deployment and deploy/README.md (written in Chinese). The app database defaults to SQLite with a single process; for multiple processes, switch to PostgreSQL (see PostgreSQL and Scaling). Read the Upgrade Notes before upgrading.

Development and testing

Before running backend tests, remove model keys from the environment; otherwise the tests might really call the API:

cd backend && env -u ANTHROPIC_API_KEY -u ANTHROPIC_BASE_URL -u ANTHROPIC_AUTH_TOKEN -u OPENAI_API_KEY \
  python -m pytest -n auto
cd frontend && npx tsc -b
node scripts/check-all.mjs   # frontend checks; start ./scripts/dev.sh first

For tests on PostgreSQL, the 43 frontend checks, and the documentation checks, see Development.
