Documentation Tasks 📚

Create EXAMPLES.md ⏳

Status: Not Started
Priority: Medium
Estimated Effort: 1 week

Key Files to Reference:

  • /CLAUDE.md - Implementation overview
  • /docs/MABEAM_API_REFERENCE.md - API documentation

Content to Include:

Current Dialyzer Issues to Fix 🚨

Priority: Immediate
Files Affected: 4 MABEAM modules

1. ProcessRegistry.register Contract Violations

Files: agent_registry.ex:139, coordination.ex:124, economics.ex:190, telemetry.ex:155

Issue: Contract expects specific return types but calls don’t match

Root Cause: ProcessRegistry.register function contract may be too restrictive

Fix Approach: Update either the contract or the calling code to match

2. Pattern Matching Issues

File: coordination.ex:1974

Issue: nil pattern can never match map() type

Root Cause: Function type signature guarantees map input but code handles nil

Fix Approach: Update function signature or remove impossible pattern

3. Function Return Issues

Files: coordination.ex:109, telemetry.ex:500

Issue: Functions have no local return or break contracts

Root Cause: Logic paths that don’t return expected types

Fix Approach: Ensure all code paths return expected types
