## Summary A single failed `advisor` call permanently disables the advisor tool for the rest of the session, even when the underlying failure is transient (rate pressure / load). The client surfaces one generic latched string — `The advisor tool is unavailable. Do not try to use it again.` — and never retries, so long-running sessions lose the advisor entire

## Summary Claude Code stores per-project state (session transcripts, `MEMORY.md`, todos, scratchpad) under `~/.claude/projects/<slug>`, where `<slug>` is derived from the **literal absolute working-directory path**. When a project's directory is relocated — e.g. `~/dev` becomes a symlink to an external drive `/Volumes/SanDisk2/dev`, or the tree is moved to

## Feature Request: Native binary for Linux RISC-V (riscv64) ### Summary Claude Code cannot run on Linux riscv64 platforms because the native binary is only distributed for x86_64 and arm64.

**Problem** There's currently no way to see when each message in a conversation was sent. In long sessions — especially ones with gaps where I step away and come back — I can't tell how long ago I asked something without manually parsing the session JSONL transcript. The transcript already stores a per-message `timestamp`, so the data exists; it just isn't s

## Summary Cross-session messaging between local sessions in the **Claude Code desktop app on native Windows** worked reliably before the app auto-updated its bundled runtime (2.1.222 → 2.1.227 on 2026-08-12). After the update, sending a message to another local session **reports success but the message is never delivered** — a silent failure with a false su
## Feature request There's no way to restart a Claude Code session from within the chat. When settings change (e.g., permission mode, effort level) or the extension needs a fresh process, the only options are: - Close and reopen the panel/tab - Use VSCode command palette → "Developer: Reload Window" (restarts the entire VSCode window) - `/clear` only clears

### Summary Over the last few days, trackpad scrolling in the Claude Code TUI became unusable on macOS in the VS Code integrated terminal. Three things changed at once: 1. **Each scroll notch now moves ~3 lines instead of 1.** Fine line-by-line scrolling is gone. 2. **The vertical scrollbar disappeared** from the right edge of the transcript, so there is no

## Summary Heavy users who run **many independently-launched Claude Code sessions against one repo with one shared working tree** have no first-party coordination story. The only real primitive is a PreToolUse `deny` hook — a build-it-yourself kit — and that kit has silent holes (below). I spent a day measuring what actually collides between sessions on my o

## Bug Setting `attribution.commit` to `""` (empty string) in `~/.claude/settings.json` does not disable the `Co-Authored-By` trailer on commits. The docs and the embedded help text both state: > Set `commit` or `pr` to empty string `""` to hide that attribution. But commits still get the trailer appended. ## Repro 1. Set `~/.claude/settings.json`: ```json {
## Summary Intermittently, the assistant's tool invocation is emitted as a plain **text block** instead of a structured `tool_use`, so the tool call is never parsed or executed. The leaked text has a consistent signature: 1. It omits the function-call namespace — it renders as `<invoke name="Bash">` instead of the proper namespaced form. 2. A stray literal t

### What happened Since the newer TUI began emitting OSC 8 hyperlink escape sequences for URLs, ctrl-clicking a link in **KDE Konsole** opens **two** browser tabs for a single click. ### Root cause (verified) Konsole has its own regex-based URL detector (`Settings → Edit Current Profile → Mouse → "Underline links"`) in addition to honoring OSC 8 hyperlinks.
