Built for what broke this month

The public monster log.

prxy.monster modules are mapped to dated, named AI coding-agent failures. When the agent ecosystem breaks in public, the module backlog changes in public.

Incident → module

Mar 19, 2026
Claude Code auto-compaction regression. A public GitHub issue describes user intent and corrections being dropped after compaction, causing scope drift and hallucinated work.
Compaction Bridge Preserve explicit user intent across compression boundaries. Source
production
Mar 16, 2026
MCP context bloat. Apideck documents MCP tool definitions consuming 55,000+ tokens before the first user message, with single tools costing hundreds to thousands of tokens.
MCP Optimizer Score tools against the request and ship only relevant definitions. Source
production
Mar 26, 2026
Rapid rate-limit drain reports. Claude Code users reported normal agentic sessions exhausting usage windows much faster than expected.
Semantic + Exact Cache Stop paying providers to reprocess repeated context and repeated prompts. Source
production
Apr 2026
AI coding-tool budget pressure. Public reports described large engineering orgs reworking AI budgets as agent usage scaled faster than forecasts.
Cost Guard Per-key daily/monthly hard caps before runaway agents turn into runaway invoices. Source
production
Apr 2026
Subscription availability churn. Claude Code plan availability and pricing tests reminded teams that hosted agent tooling can change underneath them.
MIT Local Edition Keep the gateway pipeline runnable on your laptop or private infrastructure. Source
production
Feb 20, 2026
Code Mode validates the context-footprint race. Cloudflare published a two-tool MCP server pattern using around 1,000 tokens for a large API surface.
Tool Cache + MCP Optimizer Measure repeated tool calls first; active tool-result caching remains preview. Source

The rule

A log entry does not mean prxy.monster claims ownership of the upstream incident. It means the incident is high-signal evidence that coding agents need a gateway primitive: prune, cache, remember, cap, or preserve context.

Named

Each entry links to a public issue, blog, doc, or report. Anonymous vibes do not become roadmap.

Dated

The log records when the incident surfaced and whether the response is production, preview, or planned.

Module-shaped

The output is not a thinkpiece. It becomes a pipeline module, docs, or a benchmark target.
