# 5 Free Plugins for Your Claude Code Setup: Memory, Skills, Docs — What Each One Does
**TL;DR:** The Claude Code harness already provides the foundation: model, tools, context management. The plugin layer on top is what saves real typing. Memory keeps notes across sessions, skill discovery finds matching templates, document processing reads PDFs and Excel files in a structured way, code setup scaffolds projects in one step, and the efficiency group compresses context so you can pick up where you left off faster. All five are free and up and running in under two minutes.
## What the plugin layer adds on top of the harness
At its core, Claude Code already ships with the model, the built-in tools and context management. These building blocks are included in your subscription and need no extras. Plugins sit exactly one level above: they bundle skills, custom slash commands and MCP servers into installable units. The harness stays the same; only the workflow gets faster. That layer is what is listed below — one sentence of purpose per plugin, plus a direct before/after comparison on the same task.
## 1. Memory: persistent memory across sessions
**Purpose:** Notes, decisions and project rules persist across sessions without you having to type them in again.
- ❌ Without the plugin: In every new session you re-type the project context — structure, conventions, open items. That is 5 to 10 lines per start.
- ✅ With the plugin: The saved state is loaded automatically, and the first answer lands after a single line of context.
The memory plugin writes the key points to a local notes file and reads them back at the next start. For multi-step work spread across the day, this is the biggest single gain.
## 2. Skill discovery: the right template without searching
**Purpose:** Finds the matching skill template for your type of task instead of you reciting it from memory.
- ❌ Without the plugin: You dig up the template from memory or old transcripts and copy it by hand.
- ✅ With the plugin: A shortcut is enough, and the matching structure is in the prompt as a starting point.
Skill discovery indexes the installed skills and matches them against your input. In practice this means fewer chains of typing and more reproducible answers, because every session starts with the same structure.
## 3. Document processing: understand PDF, DOCX, XLSX and PPTX directly
**Purpose:** Reads common document formats in a structured way — tables, headings and slides become searchable text.
- ❌ Without the plugin: PDF tables end up in the prompt as chopped-up text, and you fix the column mapping yourself.
- ✅ With the plugin: The structure is preserved, and questions about the table are answered from the parsed model.
Document processing covers the four formats that actually come up in day-to-day work: pdf, docx, xlsx, pptx. For reports and spec work, this is the foundation that lets the LLM work cleanly with the numbers in the first place.
## 4. Code setup: project structure in one step
**Purpose:** Scaffolds directory structure, linter and test runner as the starting point for a new project.
- ❌ Without the plugin: Create folders, type configs, add dependencies — 10 minutes of fiddling per project.
- ✅ With the plugin: One scaffold run creates the skeleton, and you only add the project-specific parts.
The scaffold includes the conventions you stored in the memory plugin. New project, one command, finished structure — including the files the rest of the toolchain expects.
## 5. Efficiency: compressed context, faster re-entry
**Purpose:** Compresses long session histories, summarizes the current state and keeps the token count low.
- ❌ Without the plugin: After 30 messages the model works with the full history, and answers get slower and more expensive.
- ✅ With the plugin: The compressed state remains complete, and getting back in after a break takes two sentences instead of a whole session.
Efficiency is the least-effort building block: no new logic, just better use of what is already there. The difference is especially noticeable on long days with many interruptions.
## Installation in three steps
```bash
# 1. Add the marketplace
claude plugin marketplace add anthropics/claude-code

# 2. Install a plugin (example: document processing)
claude plugin install document-skills

# 3. Check status
claude plugin list
```
All installations apply per project and can be removed again individually. You do not need to restart the session.
## Comparison at a glance
| Plugin | Purpose | Biggest time saver |
|---|---|---|
| Memory | Keep notes across sessions | No re-typing of context |
| Skill discovery | Find the matching template | Search-free prompts |
| Document processing | Read PDF, DOCX, XLSX, PPTX | Clean tables without rework |
| Code setup | Scaffold a project | 10 minutes of fiddling per project |
| Efficiency | Compress context | Faster re-entry |
## FAQ
**When do I need which plugin?**
Memory pays off as soon as you continue the same work across several sessions. Document processing is a must once reports or spec files are involved. Skill discovery and code setup only kick in when you regularly work on the same type of project; you will notice the efficiency compression mainly in long sessions.
**Do the plugins cost extra?**
No, all five are part of the free Claude Code setup and are not tied to a separate plan. Usage from individual runs stays within your normal usage allowance. No separate line item appears on your invoice.
**How do plugins relate to CLAUDE.md?**
CLAUDE.md is the static project context the harness reads at startup; the plugins build on it dynamically. Memory, for example, writes additions to its own note files instead of bloating CLAUDE.md. That keeps the foundation small and fast while the plugin layer keeps track of the current state of work.
**Can I remove plugins after installing them?**
Yes, each plugin can be uninstalled individually without affecting the other building blocks. Your own notes from the memory plugin remain as files and can be carried over into a new setup. A full session reset is not required.
**Where should I start if I only want to install one plugin?**
With memory, because the typing it saves adds up in every single session. Document processing comes second as soon as you work with spreadsheets and reports. You can add the other three later, once the project shows recurring patterns — then the effect is immediately visible.
