## What Was Broken (ROADMAP #251) Session-management verbs (list-sessions, load-session, delete-session, flush-transcript) were falling through to the parser's `_other => Prompt` catchall at main.rs:~1017. This construed them as `CliAction::Prompt { prompt: "list-sessions", ... }` which then required credentials via the Anthropic API path. The result: purely-local session operations emitted `missing_credentials` errors instead of session-layer envelopes. ## Acceptance Criterion The fix's essential requirement (stated by gaebal-gajae): **"These 4 verbs stop falling through to Prompt and emitting `missing_credentials`."** Not "all 4 are fully implemented to spec" — stubs are acceptable for delete-session and flush-transcript as long as they route LOCALLY. ## What This Fix Does Follows the exact pattern from #145 (plugins) and #146 (config/diff): 1. **CliAction enum** (main.rs:~700): Added 4 new variants. 2. **Parser** (main.rs:~945): Added 4 match arms before the `_other => Prompt` catchall. Each arm validates the verb's positional args (e.g., load-session requires a session-id) and rejects extra arguments. 3. **Dispatcher** (main.rs:~455): - list-sessions → dispatches to `runtime::session_control::list_managed_sessions_for()` - load-session → dispatches to `runtime::session_control::load_managed_session_for()` - delete-session → emits `not_yet_implemented` error (local, not auth) - flush-transcript → emits `not_yet_implemented` error (local, not auth) ## Dogfood Verification Run on clean environment (no credentials): ```bash $ env -i PATH=$PATH HOME=$HOME claw list-sessions --output-format json { "command": "list-sessions", "sessions": [ {"id": "session-1775777421902-1", ...}, ... ] } # ✓ Session-layer envelope, not auth error $ env -i PATH=$PATH HOME=$HOME claw load-session nonexistent --output-format json {"error":"session not found: nonexistent", "kind":"session_not_found", ...} # ✓ Local session_not_found error, not missing_credentials $ env -i PATH=$PATH HOME=$HOME claw delete-session test-id --output-format json {"command":"delete-session","error":"not_yet_implemented","kind":"not_yet_implemented","type":"error"} # ✓ Local not_yet_implemented, not auth error $ env -i PATH=$PATH HOME=$HOME claw flush-transcript test-id --output-format json {"command":"flush-transcript","error":"not_yet_implemented","kind":"not_yet_implemented","type":"error"} # ✓ Local not_yet_implemented, not auth error ``` Regression sanity: ```bash $ claw plugins --output-format json # #145 still works $ claw prompt "hello" --output-format json # still requires credentials correctly $ claw list-sessions extra arg --output-format json # rejects extra args with cli_parse ``` ## Regression Tests Added Inside `removed_login_and_logout_subcommands_error_helpfully` test function: - `list-sessions` → CliAction::ListSessions (both text and JSON output) - `load-session <id>` → CliAction::LoadSession with session_reference - `delete-session <id>` → CliAction::DeleteSession with session_id - `flush-transcript <id>` → CliAction::FlushTranscript with session_id - Missing required arg errors (load-session and delete-session without ID) - Extra args rejection (list-sessions with extra positional args) All 180 binary tests pass. 466 library tests pass. ## Fix Scope vs. Full Implementation This fix addresses #251 (dispatch-order bug) and #250's Option A (implement the surfaces). list-sessions and load-session are fully functional via existing runtime::session_control helpers. delete-session and flush-transcript are stubbed with local "not yet implemented" errors to satisfy #251's acceptance criterion without requiring additional session-store mutations that can ship independently in a follow-up. ## Template Exact same pattern as #145 (plugins) and #146 (config/diff): top-level verb interception → CliAction variant → dispatcher with local operation. ## Related Closes #251. Addresses #250 Option A for 4 verbs. Does not block #250 Option B (documentation scope guards) which remains valuable.
