4. Next, feed the results from #1 and #2 into another agent, so that it can filter out false positives, that are likely not actually duplicates of the original issue. If there are no duplicates remaining, do not proceed.
5. Finally, use the comment script to post duplicates:
- If the issue doesn't have lifecycle labels but clearly needs them (e.g., a maintainer asked for repro steps or more details), add the appropriate label.
- Comments like "+1", "me too", "same here", or emoji reactions are NOT the missing information. Only remove `needs-repro` or `needs-info` when substantive details are actually provided.
- Do NOT add or remove category labels (bug, enhancement, etc.) on comment events.

- Added `"defer"` permission decision to `PreToolUse` hooks — headless sessions can pause at a tool call and resume with `-p --resume` to have the hook re-evaluate
- Added `CLAUDE_CODE_NO_FLICKER=1` environment variable to opt into flicker-free alt-screen rendering with virtualized scrollback

- Added named subagents to `@` mention typeahead suggestions
- Added `MCP_CONNECTION_NONBLOCKING=true` for `-p` mode to skip the MCP connection wait entirely, and bounded `--mcp-config` server connections at 5s instead of blocking on the slowest server

- Fixed prompt history entries containing CJK or emoji being silently dropped when they fall on a 4KB boundary in `~/.claude/history.jsonl`
- Fixed `/stats` undercounting tokens by excluding subagent usage, and losing historical data beyond 30 days when the stats cache format changes

- Fixed MCP tool errors truncating to only the first content block when the server returns multi-element error content
- Fixed skill reminders and other system context being dropped when sending messages with images via the SDK
- Fixed PreToolUse/PostToolUse hooks to receive `file_path` as an absolute path for Write/Edit/Read tools, matching the documented behavior

- Fixed prompt cache misses in long sessions caused by tool schema bytes changing mid-session
- Fixed nested CLAUDE.md files being re-injected dozens of times in long sessions that read many files
- Fixed `--resume` crash when transcript contains a tool result from an older CLI version or interrupted write
- Fixed misleading "Rate limit reached" message when the API returned an entitlement error — now shows the actual error with actionable hints

- Changed `Edit` to work on files viewed via `Bash` with `sed -n` or `cat`, without requiring a separate `Read` call first
- Changed hook output over 50K characters to be saved to disk with a file path + preview instead of being injected directly into context
- Changed `cleanupPeriodDays: 0` in settings.json to be rejected with a validation error — it previously silently disabled transcript persistence

- Documented `TaskCreated` hook event and its blocking behavior
