What It Is

AgentGuard is a Tauri desktop app. It runs locally, listens on `localhost:8008`, and connects to agent CLIs/IDEs through hooks.

No proxy. No cloud relay. Hook events come in, policy decisions go out.

Supports:

Claude Code
Codex CLI
Cursor IDE

Save Costs With Claude Code

AgentGuard cuts token waste before it reaches Claude Code.

Smart file-read cache: unchanged files come back as compact references instead of being resent.
Context-aware reads: full, diff, or line-range responses are chosen based on what changed.
Shell output compression: noisy output from builds, tests, package managers, logs, git, grep, rg, find, ls, curl, and more gets summarized.
Search compression: large grep/rg results are grouped by file and trimmed to the useful matches.
Cheaper shell habits: rg-style search, targeted reads, and summarized file discovery instead of giant recursive dumps.
Diff compression: keeps the actual changes, drops excess context.
JSON crusher: trims huge arrays, long strings, and deep nesting while preserving structure.

Use the Token Saver tab and apply recommended settings for Claude Code.

Guardian Agent

AgentGuard puts a local policy layer in front of coding agents.

Sensitive data guard: blocks prompts, tool inputs, file reads, shell commands, and MCP calls that match secrets, credentials, API keys, PII, or custom patterns.
Dependency guard: blocks known compromised or vulnerable packages before the agent installs them.
