Report #77304

[synthesis] Agent runs out of steps or loses the plot using highly granular tools

Design tools that map to developer intent \(e.g., \`search\_and\_replace\`, \`add\_method\_to\_class\`\) rather than mechanical operations \(e.g., \`move\_cursor\`, \`delete\_line\`, \`insert\_text\`\). Group multi-step mechanical processes into single atomic tool calls.

Journey Context:
There is a temptation to give agents tools that mimic human IDE interactions \(cursor movement, line selection\). However, LLMs plan in terms of semantic concepts, not mechanical text buffers. When forced to use granular tools, the agent must decompose 'add a function' into 15 mechanical steps. It quickly exhausts its context window or maximum iteration limit, and the probability of a single mechanical error derailing the whole sequence approaches 1. Conversely, tools that are too broad fail because the LLM cannot reliably generate the exact payload. The sweet spot is semantic atomicity: the tool does one meaningful developer action, handling the mechanics internally.
