786. **`claw dump-manifests --manifests-dir` (missing value) and `--manifests-dir=` (empty) both returned `error_kind:"unknown"` + `hint:null`** — dogfooded 2026-05-27 on `87f43347` (pinpoint by Gaebal-gajae). Both missing `--manifests-dir` branches in `parse_dump_manifests_args` emitted plain `"--manifests-dir requires a path"` with no typed prefix; `classify_error_kind` had no matching arm so they fell to `"unknown"`. Fix: both branches now use `missing_flag_value:` prefix + `\n` usage hint. Integration test `dump_manifests_missing_dir_has_typed_kind_and_hint_786` covers both cases. 45 CLI contract tests pass. [SCOPE: claw-code] Source: Gaebal-gajae pinpoint + Jobdori implementation on `87f43347`, 2026-05-27.
787. **`claw --resume /tmp` (directory path) returned `error_kind:"session_load_failed"` + `hint:null`; resume error emission sites didn't apply `fallback_hint_for_error_kind`** — dogfooded 2026-05-27 on `22b423b6`. Two gaps: (1) the OS error `"Is a directory (os error 21)"` had no classifier arm, falling to generic `session_load_failed`; (2) both resume error emission paths (session load at line 3338, command execution at line 3484) called `split_error_hint` but not `fallback_hint_for_error_kind`, so API-layer errors with no `\n` always got `hint:null`. Fix: added `session_path_is_directory` classifier arm for `"Is a directory"` / `"os error 21"` messages; added `fallback_hint_for_error_kind` fallback to both resume error sites; added `session_path_is_directory` and `session_load_failed` to `fallback_hint_for_error_kind`. Unit test + integration test `resume_directory_path_returns_typed_kind_and_hint_787`. 46 CLI contract tests pass. [SCOPE: claw-code] Source: Jobdori resume-path probe on `22b423b6`, 2026-05-27.
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.
