Lines where the two differ have a tinted background and bold values. Where the data itself says which value is better (more marketplaces, a larger figure of the same marketplace, a fresher release, a verified mark on a marketplace that lists both), the better one is also marked green with ▲ and the worse one red with ▼. Where it runs, the transport, the tools, the settings, hooks, the bundle's parts, the licence and the week's changes are marked only as different: more or fewer is not better in itself.

Real-time USD cost enforcement for Claude Code. Halts runaway agentic loops mid-step before they burn through your budget. The plugin enforces real-time USD cost limits in Claude Code. It uses hooks to read the session's the moment any cap is crossed — between tool batches, between turns, or at prompt-submit time. The result: a single greedy turn cannot spiral into a $30+ spend, sessions cannot silently accumulate cost over hours, and runaway burn rates are stopped before they hurt. Five configurable USD-based caps: • Per-session total spend • Per-step (prompt → response) cost • Trailing 5-minute burn rate • Per-step subagent fan-out count • Compaction gate (blocks the expensive context-compaction model call when limits are tight) Eleven slash commands for status, runtime config, pause/resume, and an optional bottom-row indicator. The indicator shows session spend, rate, current step cost, context %, and (on Claude.ai Pro/Max) 5-hour slot consumption with an estimated USD plan value. It composes with any exis
