Capn-Hook is a persistent memory system for coding agents that saves discovered file locations and codebase structure between sessions, reducing token usage by 77% on repeated questions across 60 real developer queries on five production codebases. The tool uses file fingerprinting to automatically invalidate saved answers when underlying files change, integrating with Claude Code and Codex through session hooks that let agents ask before searching and chart answers after discovery. This reduces repeated exploration costs from minutes to seconds while maintaining correctness across all test cases.

A company determined that SDK integration requires similar effort to direct HTTP API calls, shifting the economics of SDK development. The cost of maintaining SDKs now exceeds the benefit when developers can accomplish the same task by calling APIs directly. Companies are moving toward creating agent skills that instruct AI systems how to use their APIs instead of distributing traditional SDKs.
Anthropic News
Anthropic launched Claude Science, an AI workbench that integrates scientific tools, databases, and computing resources into a single environment for researchers. The platform includes over 60 pre-configured skills for genomics, proteomics, and cheminformatics, with access to major scientific databases like UniProt, PDB, and Ensembl. Scientists can now conduct multi-step analyses with auditable results and reproducible code, with one neuroscientist reducing review-writing time from two years to weeks using the system.

SpaceXAI open-sourced Grok Build, its terminal-based AI coding agent, under the Apache 2.0 license on GitHub today, providing the agent harness, TUI, tool layer, and extension system for local or remote code editing and task management. The release includes multiple Rust crates covering the agent loop, terminal UI, file tools, and workspace integration, with configuration-based model selection supporting any inference endpoint. Developers can now audit the agent code before use, fork it for internal deployment, run it fully offline with local models, or integrate it into CI pipelines through headless mode.
