[agent\_craft] Agent makes unnecessary sequential tool calls instead of batching operations

Consolidate fine-grained tools \(read\_line, grep, read\_file\) into a single 'read\_file' tool with optional 'offset' and 'limit' parameters. Limit the total number of available tools to fewer than 10 to reduce decision latency.

Journey Context:
OpenAI's function calling best practices explicitly state that models perform better with fewer, more descriptive functions than with many narrow ones. When agents have tools like 'read\_line' and 'read\_file', they tend to chain them \('read\_file' to get length, then 'read\_line' in a loop\) wasting tokens and time. A single 'read\_file' with range parameters allows the model to fetch exactly what it needs in one call. This reduces the 'tool selection' cognitive load \(the model doesn't have to choose between 20 tools\) and aligns with the finding that attention dilutes over long tool lists. The tradeoff is slightly more complex parameter schemas, but JSON schema handles this well. This pattern is critical for latency-sensitive coding agents where sequential tool calls add 500ms\+ each.
