Top 10 Claude Code Tools & Capabilities
|
Tool / Capability |
Primary Function |
"System" Integration Power |
|
1. Bash (Local) |
Executes shell commands. |
Allows Claude to run builds,
tests, and git commands directly in your OS. |
|
2. Write/Edit |
Modifies codebase files. |
Uses advanced diffing logic
to rewrite functions without deleting your
comments or formatting. |
|
3. MCP (Filesystem) |
Enhanced file operations. |
Grants Claude the ability to
search directories, move files, and index
your entire architecture. |
|
4. Subagents |
Task delegation. |
Spawns separate Claude
instances to handle sub-tasks (e.g., one
agent writes code while another writes
docs). |
|
5. Chrome Tool |
Browser automation. |
Claude can open a headless
browser to test UI, fetch live
documentation, or debug web apps. |
|
6. Hooks (Pre/Post) |
Event-based automation. |
Auto-triggers "linters" after
a write or runs "security scans" before a
commit. |
|
7. CLAUDE.md |
Persistent memory. |
A project-level "brain" file
that Claude reads every session to remember
your specific coding standards. |
|
8. Grep/Search |
Code intelligence. |
Rapidly locates patterns
across millions of lines of code using
system-native search tools. |
|
9. Git Workflow |
Version control agent. |
Not just "committing," but
staging, branching, and resolving merge
conflicts autonomously. |
|
10. MCP (External) |
Cloud/SaaS connectors. |
Connects your system to Jira,
Slack, or GitHub via standardized protocols
to manage the "meta-work." |

Deep Dive: Maximizing System Access
To truly achieve "System Mastery" with Claude
Code, you must understand the
Agentic Loop. Claude doesn't just guess; it follows a cycle
of
Research → Execute → Verify.
1. The Power of
Bash & Permissions
By default, Claude asks for permission. However,
a "ruthless" specialist uses the
--dangerously-skip-permissions flag in secure, isolated
environments (like Docker containers) to let Claude iterate at
light-speed.
$$\text{Efficiency} = \frac{\text{Task
Complexity}}{\text{User Confirmations}}$$
2. The Model Context Protocol (MCP)
This is the "USB port" for AI. By adding an MCP
server, you give Claude physical eyes and hands on other
systems.
3. Subagents & Parallelization
For massive refactors, use
/agents. You can task a subagent to "Review every file in
/src for deprecated API calls" while you continue working
on the main feature. This is multi-threading for your
development process.
[!IMPORTANT]
Safety First: Never
run Claude Code with full system permissions on a production
server or on a machine with sensitive, unencrypted
credentials. Treat it like a junior dev with a very fast
keyboard—it needs a sandbox.
