compile_context and find_impact overlap substantially because both return callers/callees for a symbol or change, requiring an agent to read descriptions carefully to pick the right one. Their intended uses are reasonably distinct—compile_context produces token-budgeted LLM context, while find_impact answers 'what breaks'—and explain_selection and verify_retrieval are clearly separate.
All tool names follow the same snake_case verb_noun pattern: compile_context, find_impact, explain_selection, verify_retrieval. There are no mixed conventions or vague names.
Four tools is an appropriately focused set for this domain: a primary retrieval/context tool, an impact-focused variant, an introspection tool, and an evaluation tool. None of the tools feel redundant or extraneous.
The main workflow is covered: generate context, inspect impacts, explain selection decisions, and verify retrieval quality on the repo. There is a minor gap in that there is no tool to directly explore the raw dependency graph outside these retrieval wrappers, but that is a narrow gap for this tool's stated purpose.
