1. Claude Code’s open‑source status is unclear
“No, its not even source available.” – dragonwriter ### 2. Hidden/unreleased features are being hinted at
“The big loss for Anthropic here is how it reveals their product roadmap via feature flags… assistant mode … code name kairos.” – treexs
3. “Undercover mode” pretends to be human
“Undercover mode: Strips ALL Anthropic internal info from commits/PRs for employees on open source contributions.” – avar ### 4. Client‑side sentiment detection uses regex
“Regex is fast, but it’ll miss a ton of cases.” – BoppreH
5. The code feels “vibe‑coded” and low‑quality
“It’s not a particularly sophisticated tool. I’d put my money on one experienced engineer being able to achieve the same functionality in 3‑6 months (even without the vibe coding).” – catlifeonmars
6. Legal/ethical debate around the leak
“Stolen? Courts have ruled it's transformative, and it very obviously is.” – petcat
7. Real‑world usage problems and reliability worries
“Two weeks ago typing became super laggy. It was totally unusable.” – mattmanser
