Steers custom tool creation toward the plugin route by default.
The adding-tools.md guide is now explicitly for built-in core Hermes
tools only.
Key fixes:
- Plugin quickstart: ctx.register_tool() now uses correct keyword-arg
API (name=, toolset=, schema=, handler=) instead of broken 3-arg call
- Handler signature: (params, **kwargs) instead of (params)
- Handler return: json.dumps({...}) instead of plain string
- AGENTS.md: mentions plugin route before built-in tool instructions
- learning-path.md: plugins listed before core tool development
- contributing.md: separates plugin vs core tool paths
Based on PR #13138 by @helix4u.

What does this PR do?
This PR steers custom tool creation toward Hermes plugins instead of direct edits to
tools/andtoolsets.py.Recent tool-creation attempts in IDE agents and support workflows kept taking the built-in/core route because the repo context and docs made
adding-tools.mdthe most obvious path. That led people to modify Hermes itself for personal or project-local tools that should usually be plugins.This change makes the common path explicit:
