Scored across 11 tools
Most tools target a distinct action+resource (pull vs check image, single backtest vs grid sweep, transpile vs run). The coverage trio (list_coverage_topics, get_coverage_topic, check_pine_feature) overlaps conceptually, but descriptions clearly establish a list→drill-down→single-identifier hierarchy, so misselection is unlikely.
Nearly all names follow a consistent verb_noun snake_case pattern (pull_engine_image, backtest_pine, get_coverage_topic, check_pine_feature, fetch_binance_ohlcv). The only deviation is 'binance_symbols', which omits the verb prefix, and backtest_pine_grid uses an underscore suffix rather than a distinct verb.
11 tools is well within the sweet spot and each earns its place across image management, transpilation, backtesting, sweeps, coverage checks, and data fetching. No redundant or filler tools for the stated local-backtesting purpose.
Strong lifecycle coverage: image pull/verify, transpile, single and grid backtests, coverage/feature discovery, engine-param catalog, and OHLCV fetch/symbol lookup. Minor gaps exist — no explicit report listing/cleanup or a way to delete cached CSVs — but core workflows are fully served.
