Refactor CacheHandler to avoid shadowing built-in input

[tosincarik]

Summary
Rename the input parameter in CacheHandler to avoid shadowing Python’s built‑in input, and update all call sites accordingly. Behavior is unchanged; this is a small readability and safety improvement.

Changes

• lib/crewai/src/crewai/agents/cache/cache_handler.py:
  • Rename:
    add(self, tool: str, input: str, output: Any) -> add(self, tool: str, tool_input: str, output: Any).
  • Rename:
    read(self, tool: str, input: str) -> read(self, tool: str, tool_input: str).
  • Update docstrings and cache key construction to use tool_input.
• lib/crewai/src/crewai/project/utils.py
  • Update memoization helper to call:
    cache.read(tool=meth.name, tool_input=cache_key)
cache.add(tool=meth.name, tool_input=cache_key, output=result)
• lib/crewai/src/crewai/tools/tool_usage.py
  • Update cache lookup to:
    self.tools_handler.cache.read(tool=calling.tool_name, tool_input=input_str)

Rationale

• Avoids shadowing the built‑in input, which can be confusing and can trip up linters/tooling.
• Aligns with the existing TODO in CacheHandler to rename this parameter.

---

Note

Renames CacheHandler input parameter to tool_input and updates related cache key usage and call sites in tools handling and sync memoization.

• Cache:
  • CacheHandler: Rename method parameters input → tool_input in add and read; update docstrings and cache key construction to use tool_input.
• Tools:
  • agents/tools_handler.py: Update cache.add call to pass tool_input.
  • tools/tool_usage.py: Update cache.read call to pass tool_input.
• Project Utils:
  • project/utils.py: In sync memoization, switch cache.read/cache.add to use tool_input for the cache key.
