TOOL CALLS REFERENCE_

Complete reference for all tool calls available in Zaguán Blade. Add these to your Local AI system prompts to enable file operations, search, editor control, and command execution.

NOTE This does not cover Blade-specific or ZLP (Zaguán Language Protocol) tools. These are standard file/editor tools for general AI coding assistance.

[005] TOOL_RESULTS

Tool Result Handling

The 50KB / 2000 line limits apply only to tool results - what zblade sends back to the model after executing a tool (e.g., the output of read_file). These limits only apply in local mode, when the Zaguán Coder Daemon isn't handling storage.

50KB Result max size

2000 Result max lines

When truncated, the first 100 lines and last 50 lines are shown with a truncation message.

There are no size limits on incoming tool calls from the model. zblade will accept a write_file with any size content. The write_file handler itself has no caps - it writes whatever content string it receives directly to disk.

ℹ️

zblade includes dropped tool call detection. If a tool call from the model never arrives (e.g., streaming progress events complete but the final tool call with arguments is dropped server-side), zblade will catch this and surface a clear error.

[006] PATH_RESOLUTION

Path Resolution

All paths can be:

Relative Resolved from workspace root (e.g., src/main.rs)

Absolute Used as-is (must be within workspace)

⚠️

Paths outside the workspace are rejected for security.

[007] SYSTEM_PROMPT

Adding Tools to Your AI System Prompt
