788. **`claw --output-format json skills show <not-found>` emitted two JSON objects — one from the skills handler, one duplicate from the top-level error path** — dogfooded 2026-05-27 on `113145a4`. `print_skills` in JSON mode called `println!` to emit the `skill_not_found` error envelope, then returned `Err(...)`. The `?` propagation triggered the top-level error handler which emitted a second `action:"abort"` JSON envelope on stderr. Callers reading both stdout and stderr got two JSON objects with the same `error_kind` but different `action` fields — the first was the authoritative response, the second was a duplicate. Fix: replaced `return Err(...)` with `std::process::exit(1)` after the skills error JSON is emitted, mirroring the existing `is_help_action` guard pattern. Integration test `skills_show_not_found_emits_single_json_object_788` asserts exactly 1 JSON object on stdout and no JSON on stderr. 47 CLI contract tests pass.

789. **`claw --output-format json agents show <not-found>` and `plugins show <not-found>` both returned exit 0 despite `status:"error"` in the JSON** — dogfooded 2026-05-27 on `abdbf61a`. Skills was fixed in #788 (exit 1 via process::exit). Agents and plugins had the identical gap: `print_agents` had no error check at all (just println + Ok(())); `print_plugins`'s not-found branch used `return Ok(())`. MCP was already fixed in an earlier cycle (#68). Fix: added `is_error` check in `print_agents` JSON path (exit 1 when status=="error"); changed plugins not-found branch from `return Ok(())` to `std::process::exit(1)`. Existing `inventory_commands_emit_structured_json_when_requested` test updated to use `run_claw` directly for the not-found case. Two new tests added: `agents_show_not_found_exits_nonzero_789`, `plugins_show_not_found_exits_nonzero_789`. 49 CLI contract tests pass.

790. **`claw --output-format json system-prompt <unknown-option>` returned `error_kind:"unknown"` + `hint:null`** — dogfooded 2026-05-27 on `e4c3c1aa`. The unknown-option branch in `parse_print_system_prompt_args` emitted plain `"unknown system-prompt option: {other}"` for all unrecognised options except `--json` (which appended a `\n`-delimited suggestion). All non-`--json` cases fell to `unknown+null`. Fix: replaced bare format string with `unknown_option: ... \n<usage hint>` format for all unknown options; `--json` special case preserves its `--output-format json` suggestion in the hint prefix. Integration test `system_prompt_unknown_option_returns_typed_kind_790` covers both paths. 50 CLI contract tests pass.
