calva-backseat-driver

Effective use of the Backseat Driver extension and its tools for Clojure interactive programming. Use when: working in Clojure (including all dialects and runtimes) project, be it reading, planning, developing, or evaluating code in the REPL, looking up function documentation or ClojureDocs examples, choosing REPL sessions, editing Clojure files structurally, checking REPL output, planning implementations, reviewing code, or developing solutions incrementally. Whenever you consider any of these tools: clojure_evaluate_code, clojure_load_file, clojuredocs_info, clojure_list_sessions, clojure_symbol_info, clojure_repl_output_log, clojure_edit_files, clojure_balance_brackets. Also use this skill when PLANNING or DISCUSSING Clojure development approaches — not only at the moment of REPL evaluation.

E2E test authoring for Backseat Driver. Use when: writing, modifying, or debugging e2e tests under e2e-test-ws/, adding new MCP test scenarios, investigating test failures, understanding test infrastructure, or working with files matching *_test.cljs in the e2e workspace.

Backseat Driver extension internals — Ex framework contracts, app-db state architecture, MCP socket server lifecycle, enrichment system, Datascript output log, activation sequences, and namespace reference. Use when: modifying core extension code, debugging state issues, working with app-db or Ex framework, understanding activation or MCP server flow, investigating enrichment or Datascript connections, or working with tool registration.

Testing strategies for Calva Backseat Driver MCP tools. Use when: Testing Backseat Driver, validating tool updates, testing structural editing workflows, verifying REPL evaluation with who-tracking, testing shadow-cljs runtime discovery and targeting, testing output log filtering, testing load-file tool, smoke testing after dep bumps, or debugging tool behavior. Covers all Backseat Driver tool categories: structural editing, REPL eval, load file, symbol info, bracket balancing, output log, and shadow-cljs runtime targeting.

Structural editing of Clojure files using Backseat Driver tools. Use when editing or planning edits: creating/adding/inserting/replacing/deleting top-level forms, fixing bracket balance, resolving indentation issues, planning multi-edit sequences, recovering from failed edits, or working with Rich Comment Forms in Clojure files, regardless of dialect or runtime. Use whenever you consider any of these tools: clojure_edit_files, clojure_balance_brackets. Use when editing Clojure and unsure which tool to pick. Use this skill when PLANNING or DISCUSSING Clojure file edits — not only at the moment of editing.
