 759. **`--model badmodel --output-format json` returned `error_kind:"invalid_model_syntax"` but `hint: null`** — dogfooded 2026-05-26 on `b8b3af6f`. `validate_model_syntax()` had hint text embedded after a period in the error string (no `\n`), so `split_error_hint()` could not extract it. Affected paths: (a) generic invalid format `"invalid model syntax: '{}'.  Expected ..."` — joined with `.` not `\n`; (b) spaces-in-model `"contains spaces. Use ..."` — same issue; (c) empty model string — no hint at all. Fix: added `\n` before hint text in all three format strings in `validate_model_syntax`.

 760. **`agent_not_found` and `plugin_not_found` error envelopes lacked `hint` field** — dogfooded 2026-05-26 on `ef31328a`. `claw agents show nonexistent-agent --output-format json` returned `error_kind:"agent_not_found"` with `hint: null`; same for `claw plugins show`. Both structured JSON envelopes in `commands/src/lib.rs` and `main.rs` omitted `hint`. Fix: added `"hint": "Run \`claw agents list\` to see available agents."` to the `agent_not_found` envelope; `"hint": "Run \`claw plugins list\` to see available plugins."` to the `plugin_not_found` envelope.

+761. **`mcp show <nonexistent>` and `skills show <nonexistent>` returned `hint: null`** — dogfooded 2026-05-27 on `7fa81b5d`. `server_not_found` envelope in `render_mcp_show_json` and `skill_not_found` envelope in `print_skills` JSON path both lacked `hint` fields, unlike `agent_not_found`/`plugin_not_found` fixed in #760. Fix: added `"hint": "Run \`claw mcp list\` to see configured servers."` to `server_not_found` and `"hint": "Run \`claw skills list\` to see available skills."` to `skill_not_found`. All four `*_not_found` envelopes now have hints. Source: Jobdori dogfood sweep on `7fa81b5d`, 2026-05-27.
