0.2.153 adds a snapshot field to SystemPromptPreset. Set True and the session keeps the system prompt recorded on its first request, improving prompt-caching across resumed sessions; set False and the prompt rebuilds every request, which is what you want while iterating on append text. Requires CLI 2.1.257+. Small surface, real cost line for long-lived sessions where a rebuilt system prompt silently invalidates the cache every turn.

86,600 stars. Six third-party plugin repos above 450 stars. Two of them created *before* the public repo existed. DeepSeek released DeepSeek Harness (dsh) on August 13 under MIT. Every capability is a swappable plugin: models, tools, skills, sessions, sandboxes, storage, loops...
5.8k stars, Rust, macOS, ~40 MB versus ~67 MB upstream, keeping full Lua customization. Command-failure recovery with suggested fixes applied via Cmd + Shift + E, natural-language-to-command via # <description>, preconfigured integration for Claude Code, Codex, Gemini CLI, and...
agentic-kv-cache simulates cross-request prefix caching against real traces, not synthetic ones: 68,266 requests across 393 Claude Code sessions at 64-token blocks, plus Mooncake traces at 512-token blocks. It models prefix-contiguous hits, radix eviction constraints and pinne...
Marcel Pociot's experimental app, published September 14 at 173 stars two days later, routes system-level Siri and Shortcuts requests to a local Claude Code session with its tools and file access instead of to Apple's own model. Small repo, but the first concrete example of Ap...
perf(agent): stabilize system prompt prefix (#19297) keeps the prompt cache warm across turns rather than invalidating it whenever the prefix shifts. Also parallelized independent config pipelines, parallelized device metadata reads during backup, and anchored relative dates i...
ARahim3/cachebeat, created September 14, addresses one specific expensive failure: leave a session idle past the cache window and your next message re-reads the entire conversation uncached, which on a long tool-heavy session is hundreds of thousands of tokens. 93 upvotes on r...
