Anthropic’s Applied AI playbook reframes Plan/Design/Build/Test/Deploy/Maintain as a loop of committed artifacts (intent.md → spec.md → plan.md → PR → production) with Claude Code plan mode, skills as institutional knowledge, hooks as deterministic gates, continuous evals in CI, and production control bands that write the next intent.md. Humans stay at judgment gates; agents do the rest. Companion pieces cover securing an AI-native SDLC and Claude Academy course modules.

Rust MCP server makes Claude Code the team lead over Claude/Codex/Gemini workers; Stop-hook + asyncRewake pushes replies (~50ms) into the lead session, with a local live team UI.
junegunn (fzf author) documents how shell CTRL-T bindings die once you live in an agent prompt—and how tmux PREFIX bindings restore fzf: tmux-fzf-complete (files/dirs/URLs/on-screen paths/sentences) and fzf-git.sh (commits, branches, PRs) inject selections as keystrokes into Claude Code or Codex. Requires tmux 3.7+ floating panes and agent settings that keep scrollback (/tui default for Claude Code; Codex alternate_screen=never). Pattern: make agent prompts as completable as the shell.
Show HN (Oct 17): RugSnare pins each MCP tool's {name, description, inputSchema} by canonicalized SHA-256 at install, then diffs upgrades across 24 popular servers (~3.6M weekly installs)—336 contract changes found; grades BREAKING/LOOSENED/EXPANDED/NOTATION/COSMETIC and exits 1 for CI. Apache-2.0, zero npm deps; OWASP MCP Security Cheat Sheet now recommends contract pinning.
Show HN: `npx subagent-reuse --setup` adds an MCP that scans ~/.claude/projects/, builds SHA-256 Merkle trees of files each subagent already read/modified, and route_task decides REUSE vs CREATE_NEW before spawn—structural overlap only, no embeddings; ~1k LOC JS + 52 tests.
