A Claude Code plugin that keeps the **prompt cache** warm while you step away, then compacts the conversation **once** and waits for you.

claude code 2.1.300 is worth your update, and the reason is mods. the headline change: agent.spawn hooks can now rewrite a workflow agent's prompt and model at spawn time. before, a hook could only refuse the agent. that turns routing into code: cheap model for doc sweeps, strong model for the actual fix. also in: prompt.change fires on non-typed prompt changes (history recall, undo, plugin fill), /advisor lands on claude platform on aws, and otel spans now carry genai semantic-convention attr

Draws your plan usage limits as bars above the prompt, one colour per window, flagging when you are using a window faster than its clock. Toggle with /usage-bar.

A 3-minute hands-on tutorial covering what Claude Code mods are, installing and disabling them with /plugin, validating with claude plugin validate, authoring one with Claude, and testing offline with claude plugin test.

A status bar for Claude Code. It sits above the prompt in the terminal and in the desktop app (Windows 11) and shows at a glance how full your context is, how much of your plan limits you have used, when the prompt cache expires and whether Anthropic's services are up. A few buttons handle everyday steps with one click, and the bottom line shows tonight's sky and the weather where you are.

A Claude Code mod that tells you when your prompt cache silently dropped to a 5-minute TTL, measured from the session transcript, with zero model calls and no settings edits.

A file explorer pane for Claude Code. `/tree` opens your project beside the conversation, so you can browse it, preview files and hand them to Claude without leaving the session.

Reddit shares two small Claude Code plugins: UsageBar shows usage, weekly limit, and context usage in the footer; QuickSkill (operated with /fav) lets you toggle commonly used plugins at the bottom, using claude plugin enable/disable without restart.

A Claude Code mod that opens a pane in Claude Code to show in real time what the Codex work dispatched by the current Claude session is doing.

I built optimAIzr , a free, open-source tool to optimize Claude Code + Codex usage. I’m a senior SWE who uses Claude daily. When I analyzed my own logs, I found that 56% of the cost went toward rereading conversation context. Cache expiry was particularly painful: 35 late returns in 27 days cost $98.74 at API prices vs. $2.95 with a warm cache. I built optimAIzr to help identify these issues, recommend optimizations, and simulate and verify potential savings. It also includes live usage insights, session-level cost analysis, and an optional Claude Code mod with per-answer costs and a 5-hour usage window. It’s local-first, requires no account, and never uploads your prompts. git: https://github.com/blendbunjaku/optimaizr (~50stars alrdy) web: https://optimaizr.com Thanks! submitted by /u/stichstichstich to r/SaaS [link] [comments]
