01
Agent-first Runtime
Run agents as managed daemons with session context, tool access, and reachable surfaces through CLI, SDK, or Console.
Features
Infrastructure for Real Agents
Downcity gives builders the reusable runtime layer that agent products keep rebuilding.
02
Memory & Context
Sessions, logs, runtime state, and task artifacts keep agent behavior visible and continuous across interactions.
03
Reusable Layer
One runtime for models, tools, tasks, memory, services, and operations across many products and entry points.
04
Tools & Plugins
Add capabilities through plugins, skills, City APIs, and SDK extensions without forking the whole backend.
05
Governed Execution
Runtime boundaries, permissions, audit logs, and operator surfaces keep execution inspectable and recoverable.
06
Multi-surface
Embed agents into CLI workflows, browser apps, desktop consoles, or third-party platforms with the same backend.
Use cases
One runtime, many product shapes.
Research Assistant
Let agents collect sources, summarize findings, and maintain a living knowledge base across sessions.
Report Generation
Turn structured data and long-form notes into consistent drafts with traceable source references.
Learning Companion
Answer questions, explain code, and guide users through complex documentation without losing thread.
Knowledge Base
Index repo docs, notes, and API references so agents answer from your actual content instead of generic training data.
Publishing Workflow
Draft, review, and publish content through agent-assisted pipelines with human approval at every checkpoint.
Knowledge Layer
Documents, embeddings, and structured context live close to the agent so answers are grounded and auditable.
01Agent Layer
Models, system prompts, sessions, and memory form a reusable brain that can be attached to any surface.
02Action Layer
Tools, plugins, tasks, and permissions turn model outputs into real, governed operations inside your workspace.
03Config Surface

# Market Research
1. Gather primary and secondary sources.
2. Record citations for every material claim.
3. Compare competitors on one shared rubric.
4. Save the final report under ./reports/.
Builder Decision
Ship Agent Products
Close one real agent product loop on a reusable runtime, then expand it into more workflows and product surfaces.
