Tip-only Claude how-tos for professional developers.
At a glance Claude Corner tip One install command can add a plugin marketplace you haven’t registered yet and install the plugin from it. The in-session form, /plugin install with –marketplace, needs v2.1.275 or later, which every npm channel had at 8:42 AM ET, stable included. The shell form, claude plugin install with –marketplace, needs … Read more
At a glance Claude Corner tip Since v2.1.234, an interactive Claude Code session on a claude.ai subscription waits out a usage limit and continues the task after the reset, if you leave it open. It is on by default, but a project settings file, a permission prompt or a sleeping machine can stop it quietly. … Read more
At a glance Claude Corner tip Claude Code v2.1.288 and later accept –max-findings on the local /code-review command, with a number N, all, or default. The value is sticky: later reviews reuse it until you pass default, so reset when you are done. On the morning of 7 October 2026, npm latest and next were … Read more
At a glance Claude Corner tip Claude Code v2.1.288 and later can restore a draft you cleared with one idle Ctrl+C: with the prompt empty, press Up, and the draft comes back, including pasted text and images. The npm latest channel already has that recovery, while stable is still on a build that does not, … Read more
At a glance Claude Corner tip Claude Code v2.1.285 and later can turn off the WebFetch tool with CLAUDE_CODE_DISABLE_WEB_FETCH=1, and the WebSearch tool stays available. The npm stable channel already includes that floor, so you do not need latest just to drop page fetch from a session. A domain allow rule and the sibling deadline … Read more
At a glance Claude Corner tip In Claude Code agent view, every prompt you type at the bottom starts a new session, so retyping a word to find an old session creates a duplicate instead. Claude Code v2.1.287 (1 Oct 2026) adds an n: prefix that turns the same box into a filter on session … Read more
At a glance Claude Corner tip Claude Code v2.1.282 added maxProseWidth, a settings.json key that wraps paragraphs, headings, lists, and blockquotes at a column count you pick while tables and code blocks keep the full terminal width. It takes a whole number of columns, minimum 40, and Claude Code ignores any other value. The docs … Read more
At a glance Claude Corner tip Claude Code v2.1.285 adds claude plugin configure, which shows a plugin’s options and which are unset, or saves values piped into –values-stdin. claude plugin install –config now also takes <server>.<key>=<value> for a bundled .mcpb server’s own settings, and –values-stdin does not accept those keys. The plugin docs pages still … Read more
At a glance Claude Corner tip Claude Code v2.1.284 added a fix: when a compacted request is still too long, it compacts once more and keeps less of the recent conversation. Only the changelog describes this second pass, and no documented setting or environment variable controls it, so treat it as a safety net, not … Read more
At a glance Claude Corner tip Press Esc twice on an empty prompt, or run /rewind, to back out of a bad Claude Code turn instead of correcting it. Choose Restore code, Restore conversation, or both, knowing that files changed through Bash and most subagent edits are not in the checkpoint. Run v2.1.260 or later … Read more
