From the lab.
Notes on agents, blockchain, and the tools we're building.
Connecting agents, wallets and sponsored apps
New Sigma, Droplit and BSV MCP releases bring identity, sponsor discovery and wallet proofs together, with people in control of approval.
Lean machine, continued: what we optimized next
We cut the prompt-engineer agent body from 8,713 to 2,984 words, reused session context in OpenCode, and checked setup across 204 playbooks.
Lean machine: how we rebuilt our agent tooling in one day and cut startup cost 90%
bopen-tools cost 29,260 tokens of context at the start of every session before it did any work. Compressing its routing metadata took that to 13,174 with everything installed, and splitting the catalog into a core plus nine optional modules takes a typical session to 2,498. Every step was verified against a routing eval, using a runner Claude Code shipped in July that its changelog never mentions.
Running One Agent Roster Across Claude Code, Codex, and Grok Build
bOpen ran the same persona — Parker, the read-only research analyst — through Claude Code and the two external lanes it dispatches to, Codex and Grok Build. The commands and transcripts below show the roster travels intact, unmodified.
Fetching Pages Through a Real Browser: the agent-browser WebFetch Hook
core intercepts Claude Code's WebFetch and serves pages through headless Chrome instead. Benchmarks: client-rendered docs pages go from a 10-byte shell to complete content, in about 1.5 seconds.

Explore the bOpen Plugin Marketplace with BSV blockchain tools, ordinals support, and AI-powered development utilities for Claude Code.
