Claude Code usage governor: compact professional output, context slimming, tool-output filtering, telemetry, and drift guardrails.

Claude Code governance framework that applies guardrails, guidance, and automated enforcement to projects

Ephemeral data sandbox for AI workflows with guardrails and security

Enables auditing MCP configuration token usage, compressing tool catalogs, pruning bloated JSON responses, and optionally persisting compressed profiles under read-only defaults and safety guardrails.

A free, read-only server that lets users diagnose production AI-agent risks: it flags over-privileged API keys from permission descriptions, scans code snippets for the signals that prevent duplicate execution, and explains guard patterns such as idempotency keys, approval gates, outboxes, and circuit breakers. It makes no network calls or writes, and rejects inputs that look like real secrets.

Enables an AI agent to check live GPU prices, get a cost quote, rent a per-minute GPU instance, upload code and data, run jobs in the background, tail logs, download results and destroy the instance to stop billing. Includes guardrail limits on spend, hours and idle time, safe file transfer, and access to an OpenAI-compatible model API for inference without renting a GPU.

Keep Claude Fable 5 in the chair all day without draining your usage limit — token-frugal multi-agent orchestration plugin for Claude Code: tier routing (Sonnet 5 does the work), Requirements Ledger, enforced guard hooks, automatic teammate reaping

Background automation runner for DSH: isolated agent runs, script/HTTP/SSH/Docker runtimes, cost guard, notifications, heartbeats.

Guardian agent for AI coding: four frontier models review risky diffs and commits before they ship.

Hierarchical Claude Code-style persistent memory for DeepSeek Harness: user + project (git-shared) scopes, session-start auto-injection, MEMORY.md index guards. Pure files, zero dependencies.

EPO/USPTO search, citations, OCR, plus PATSTAT Portfolio Analytics, guarded SQL and Graph Analytics.

Mission control for long Claude Code runs: context and run progress at a glance, Autopilot handoffs, guardrails and a calm activity view, in the terminal and Claude Desktop.

AI 写长篇的四个死法：设定崩、看不见前文、水文超字数、满屏 AI 味——这个插件全用代码堵死。细纲不批准就不给写章，设定改值直接拒绝，重复句段机审拦下，六维去 AI 味扫描零 token。右侧栏锻炉面板带听书、全书体检、批量起草断点续跑；20 个 novel_* 工具，你只管讲故事，把关交给代码。Novel-writing guardrails plugin for DeepSeek Harness (DSH).

Guarded context compaction for DeepSeek Harness (dsh): the LLM proposes, deterministic guards dispose — eager per-atom shrink (extract/summary/false under verbatim guards) + lazy reference-graph eviction (0-LLM) + byte-exact recall from an append-only log

Official Huawei Cloud plugin for AI agents — skills, MCP tools, safety guardrails, and cloud sandbox to help AI agents build, deploy, and operate on Huawei Cloud securely.

DeepSeek Harness fast mode: fewer round trips at the same thinking effort. Adaptive parallel tool fan-out, output discipline that never trims the answer, a cancellable stall guard, and one off-by-default switch (lazy) that steps a stalled turn one rung do

"ULTRASHIP" Claude Code plugin — 39 skills, 33 tools, 11 agents for ship-ready workflows: planning, review, pentesting, safety guardrails, canary monitoring, SEO/AI-readiness check, penetration testing, code review, competitive analysis, incident response. 1 dependency. 180 tests. MIT.

Guardrails for LLM output: pass / fail / review verdicts and one recommended action. Hosted or npm.

DSH plugin for smart checkpoints, workspace safety guards, and instant rollback

Automatic strong/cheap model-tier routing for DeepSeek Harness: intent-gated tier landing on the agent/request waterfall, plan-mode handoff (strong plans, cheap implements), deterministic high-risk guards on tools/pre-execute, failure escalation with TTL

Customize the dsh UI theme: 12 accent presets, dark-mode aware accents with a contrast guard, density, font family, animation toggle, and raw design-token overrides.

Claude Code plugin suite: brewcode (skill/agent/rule authoring, semble semantic search, superreview and teams setups), brewdoc (doc sync, PDF, publish), brewtools (text optimization, secrets scan, deploy, SSH, subagent guards)

DeepSec — AI Security Offense & Defense Platform. Shield audits AI-generated code for hallucinated packages, missing safeguards & AI pattern errors in real time. Spear automates authorized penetration testing with 40+ skill packs, from recon to PoC.

Enables MCP clients such as Claude to read temperatures, fan speeds, power and clocks from a CoolerControl daemon, and to change fan profiles, fixed duty speeds, modes, functions, alerts and custom sensors through its REST API. Write operations are gated behind a token with write access, with an optional minimum-duty floor guarding against accidentally stopping a pump or fan.
