## Problem `claw config` and `claw diff` are pure-local read-only introspection commands (config merges .claw.json + .claw/settings.json from disk; diff shells out to `git diff --cached` + `git diff`). Neither needs a session context, yet both rejected direct CLI invocation: $ claw config error: `claw config` is a slash command. Use `claw --resume SESSION.jsonl /config` ... $ claw diff error: `claw diff` is a slash command. ... This forced clawing operators to spin up a full session just to inspect static disk state, and broke natural pipelines like `claw config --output-format json | jq`. ## Root cause Sibling of #145: `SlashCommand::Config { section }` and `SlashCommand::Diff` had working renderers (`render_config_report`, `render_config_json`, `render_diff_report`, `render_diff_json_for`) exposed for resume sessions, but the top-level CLI parser in `parse_subcommand()` had no arms for them. Zero-arg `config`/`diff` hit `parse_single_word_command_alias`'s fallback to `bare_slash_command_guidance`, producing the misleading guidance. ## Changes ### rust/crates/rusty-claude-cli/src/main.rs - Added `CliAction::Config { section, output_format }` and `CliAction::Diff { output_format }` variants. - Added `"config"` / `"diff"` arms to the top-level parser in `parse_subcommand()`. `config` accepts an optional section name (env|hooks|model|plugins) matching SlashCommand::Config semantics. `diff` takes no positional args. Both reject extra trailing args with a clear error. - Added `"config" | "diff" => None` to `parse_single_word_command_alias` so bare invocations fall through to the new parser arms instead of the slash-guidance error. - Added dispatch in run() that calls existing renderers: text mode uses `render_config_report` / `render_diff_report`; JSON mode uses `render_config_json` / `render_diff_json_for` with `serde_json::to_string_pretty`. - Added 5 regression assertions in parse_args test covering: parse_args(["config"]), parse_args(["config", "env"]), parse_args(["config", "--output-format", "json"]), parse_args(["diff"]), parse_args(["diff", "--output-format", "json"]). ### ROADMAP.md Added Pinpoint #146 documenting the gap, verification, root cause, fix shape, and acceptance. Explicitly notes which other slash commands (`hooks`, `usage`, `context`, etc.) are NOT candidates because they are session-state-modifying. ## Live verification $ claw config # no config files Config Working directory /private/tmp/cd-146-verify Loaded files 0 Merged keys 0 Discovered files user missing ... project missing ... local missing ... Exit 0. $ claw config --output-format json { "cwd": "...", "files": [...], ... } $ claw diff # no git Diff Result no git repository Detail ... Exit 0. $ claw diff --output-format json # inside claw-code { "kind": "diff", "result": "changes", "staged": "", "unstaged": "diff --git ..." } Exit 0. ## Tests - rusty-claude-cli bin: 177 tests pass (5 new assertions in parse_args) - Full workspace green except pre-existing resume_latest flake (unrelated) ## Not changed `hooks`, `usage`, `context`, `tasks`, `theme`, `voice`, `rename`, `copy`, `color`, `effort`, `branch`, `rewind`, `ide`, `tag`, `output-style`, `add-dir` — all session-mutating or interactive-only; correctly remain slash-only. Closes ROADMAP #146.
