5 plugins that seriously upgrade Claude Code

Aggregates more than 350 providers behind a single endpoint. You point tools like Claude Code, Cursor, or Codex at it; when one provider hits its limit, it automatically falls back to another. So you don't stop mid-task because of a rate limit.

npm install -g omniroute
omniroute

# Dashboard: http://localhost:20128
# Before connecting a provider, check its terms flag
# on the Free Tiers page and skip anything marked avoid.

# For Claude Code, in a second terminal:
omniroute run claude --model auto

# For tools like Cursor, Codex, Cline:
#   Base URL: http://localhost:20128/v1
#   API Key:  copy from Dashboard → Endpoints
#   Model:    auto

Needs Node 22.22.2 or above, or 24 through 26. When connecting Claude Code by hand, do not add /v1 to the address; that is only for other tools. Kiro AI and OpenCode Free, which the README suggests, are flagged avoid in the project's own terms of service table. The 'npm warn ERESOLVE' warnings during install are harmless. The detailed setup with every pitfall is at number 115.

Claude Code meets you from scratch every session; this plugin fixes that. It compresses and stores context from previous sessions and restores it automatically when you open a new one. On long-running projects it saves you from explaining everything again each time.

npx claude-mem install

# Or from inside Claude Code:
/plugin marketplace add thedotmack/claude-mem
/plugin install claude-mem

# Restart Claude Code after installing.

'npm install -g claude-mem' does NOT install it; that only pulls the library, it doesn't register the hooks. Use one of the two methods above.

Compresses everything your agent reads (tool outputs, logs, files, conversation history) before it reaches the model. Around 60-95% savings on JSON data and 15-20% on coding agents. Same answers, smaller bill.

# Python tool (not Node)
uv tool install --python 3.13 "headroom-ai[all]"
# or: pip install "headroom-ai[all]"

headroom wrap claude     # wrap Claude Code
headroom doctor          # verify the setup
headroom dashboard       # watch the savings live

This is a Python tool, not Node. 'npm install headroom-ai' only gives you the TypeScript SDK; it does not ship the 'headroom' CLI.

Scans your project and recommends the hooks, skills, MCP servers, subagents, and slash commands that fit it. Read-only; it never modifies your files. The fastest path to a correct setup if you're new to Claude Code.

# Inside Claude Code:
/plugin install claude-code-setup@claude-plugins-official

# Then just ask:
"recommend automations for this project"

It watches in the background while you work: the corrections you make, the tasks you repeat, and the gaps no skill covers yet. Then it proposes new skills and updates existing ones. It observes itself too. Its author reports applying 900+ improvements across 50 skills in the first six months.

# Download the repo as ZIP (Code → Download ZIP) or clone it.
# Keep SKILL.md and the references/ folder TOGETHER.

# For Claude Code:
.claude/skills/task-observer/
  ├── SKILL.md
  └── references/

If you only drop in SKILL.md it runs degraded; the references/ folder is required.
