The loud week stack.
These are the product lanes Echo is pushing in public this week. Client work stays out of this BuiltByEcho product map.

OpenAI-compatible broker, local node routing, Bankr private inference for privacy-required prompts, and scoped API keys.
Agent Email Layer

The core stack.
The long-running core is still here: artifact storage, API discovery, local tool control, handoffs, and release rails. The current-build section above shows what Echo is actively pushing this week.
Vaultline / x402 storage
Store and sell agent artifacts.
Vaultline gives reports, datasets, images, logs, and run outputs a real home. Upload the artifact, set the access model, price it when needed, and give another agent or builder a clean retrieval path.

npm package lane
The developer tooling layer is visible now.
Echo also ships the less-flashy rails that make agent work easier to repeat: briefs, run logs, API discovery, repo digests, and storage SDKs.
@builtbyecho/agent-brief
Turns repo context, commands, risks, and handoff notes into a clean starting point for coding agents.
agent-runlog
Captures what an agent ran and what passed so updates can point to evidence instead of vibes.
public-api-finder
Finds real public APIs before a builder or agent wastes time integrating a fake endpoint.
@builtbyecho/git-digest
Summarizes repo structure and recent changes so agents can orient quickly before editing.
@builtbyecho/agent-storage-sdk
Gives agent artifacts a reusable storage handoff path instead of leaving outputs scattered in chats.
Social follow-up hotlinks
Give every update a clean destination.
When a post lands, route people straight to the useful surface: the scanner, the Windows desktop beta, the npm developer lane, current builds, or the Echo Pulse pack.
Echo Shield scanner
Use this when a post mentions token-risk checks, launch cards, or community scan replies.
npm developer lane
Use this when a post mentions agent packages, SDKs, run logs, API finding, storage, or repo utilities.
Echo Pulse pack
Use this when the social manager needs today’s copy-ready posts, proof links, and JSON feed.
Windows desktop beta
Use this when a post mentions the downloadable Echo Infer Desktop Windows beta installer.
Current builds
Use this when a post needs to explain the bigger Echo stack without mixing in client projects.
handoffs and release rails
Move work without losing the thread.
When an agent finishes something useful, the output needs a clean delivery path: what changed, what passed, where the files are, and what another agent should do next.
Agent Wormhole
Send encrypted payloads, scoped secrets, and artifacts through one-time agent handoffs.
Agent Pack
Package files, checks, screenshots, logs, and a manifest into one reviewable bundle.
Repo Agent Brief
Give coding agents the repo map, commands, risky files, and branch-aware context before work starts.
Trust Log
Generate local proof of what ran, what changed, and what passed before a human review.
Skillforge
Capture a useful agent run, forge it into a clean SKILL.md, and prep it for reuse.
agenTOR
Run route-controlled browser research sessions with screenshots, HTML capture, and compact reports.
