🚀 Anthropic Official
Compliance API now covers local Cowork and Claude Code sessions
Adds GET /v1/compliance/apps/sessions/local (and per-session/messages endpoints) so Enterprise compliance teams can pull consolidated transcripts of Cowork and Claude Code sessions that run on users' own machines, in beta.
Claude Code v2.1.228
Fixes interactive sessions that stopped redrawing after a rare layout error, Git/Git Bash not being found on Windows when launched from a parent folder, /tui reverting to an earlier model after /model changes, Remote Control leaking conversation history into a connected session, and cross-session messaging starting without an inbox; hardens skills synced from claude.ai against shadowing local commands.
Claude Sonnet 5 pricing made permanent
The introductory $2/$10 per Mtok rate is now standard; the scheduled September 1 increase to $3/$15 will not happen.
Claude Code v2.1.227
Fixes feature flags evaluating without subscription tier on expired-token session starts, Bash commands failing under claude-code-action with allowed_non_write_users, and /tui restoring rewound conversations; improves slash-command menu performance.

💡 Community — Workflows & Ideas
How to organize Claude Code for product work
Recommends splitting a Claude Code workspace into stable-context, active-project, and dated-notes folders, with a two-minute filing habit that routes every correction into preferences, context, or skills so fixes compound instead of repeating (35 points, 26 comments).
Claude finds a new lowest-ever counterexample to Borsuk's Conjecture
An independent researcher has Claude identify a set of 321 points in ℝ⁶³ that can't be split into 64 smaller-diameter subsets, pushing the smallest known dimension where the conjecture fails down from 64 to 63.
Why does CLAUDE.md keep growing? Catastrophic remembering in agentic coding
A study of 247,694 instruction lifetimes across 1,867 repos finds agentic prompt files more than triple over their lifetime because deleting an instruction without its rationale risks a regression; annotating instructions with reasoning cut excess growth by 99.3% in tests.
Watermark backlash: a removal tool appears, and a rebuttal explains why most can't work
Days after Claude's content watermark shipped, a "remove the watermark" tool surfaces alongside a technical rebuttal arguing most such tools can't actually strip a signal embedded in word-choice rather than invisible characters.
Show HN: Parley — your coding agent can talk to a teammate's agent
Builds an append-only, audit-logged coordination layer so separate coding-agent sessions can message each other asynchronously and escalate blocking issues to humans, echoing Anthropic's own cross-session messaging feature with a cross-tool version (9 points, 5 comments).
