Should we remove tool count assertions from test cases?

[paikend]

Issue

We have test assertions like:

assert mock_mcp.tool.call_count == 5

Problem

• Every time we add/remove tools, tests break
• Not clear what value this provides
• High maintenance cost

Proposal

Remove call count assertions and focus on testing:

• Tool behavior and functionality
• Tool schemas
• Error handling

Question

Do these call count assertions provide meaningful value?

If not, let's remove them.

Context

From code review discussion in PR #75

Checked our code and there aren't many cases with hardcoded counts. Let's just agree on this internally and wrap up the discussion!
