`man` and `math` duplicated capabilities already reachable through `bash`; `plan_agent` is better expressed as a `task_agent` running a planning skill, and carried a large amount of special-case machinery (plan-review gate, refinement loop, per-kind model routing). Removing all three shrinks the tool surface and cuts per-call token cost. Also removed, as dead-once-the-tools-are-gone: - the `math` sandbox executor (`turnstone.core.sandbox`) and its `[sandbox]` extra; the eval analyst now runs bash-only - the read-only `AGENT_TOOLS` sub-agent tool set and the `agent` tool-metadata key (`task_agent`/`TASK_AGENT_TOOLS` retained) - the plan-review protocol end to end: the `on_plan_review` UI hook, `resolve_plan`, `POST /v1/api/plan` + `POST /v1/api/route/plan`, the `plan_review`/`plan_resolved` SSE events, and their Python SDK / TypeScript SDK / OpenAPI / frontend / Discord+Slack bindings - the `model.plan_alias` / `model.plan_effort` settings and the registry `plan_model` / `plan_effort` routing fields TOOLS 31->28, TASK_AGENT_TOOLS 13->11; COORDINATOR_TOOLS unchanged. BREAKING CHANGE: removes the `man`, `math`, `plan_agent` tools, the plan-review SSE/HTTP/SDK surface, and the plan_* model-routing settings from the experimental 1.6 line.
