Use when rendering tool calls, tool messages, structured tool outputs, status cards, fallback JSON/text displays, parser boundaries, display status mappings, or unknown tool results.\n---\n\n# Tool Renderer Contract\n\n## Skill Interface\n\n- Name: tool-renderer-contract.\n- Description: Design and review structured tool-result rendering for tool calls, tool messages, structured tool outputs, status cards, fallback JSON or text displays, parser boundaries, display status mappings, and unknown tool results.\n- Parameters: Tool result schema, raw message content, parser boundary, display status mapping, known specialized renderers, fallback rendering behavior, sensitive field policy, and verification cases.\n- Instructions: Use this skill when rendering tool output in UI. Parse raw output as untrusted data, validate minimum structured fields, map status through a closed display union, provide safe fallbacks for unknown tools, and verify malformed, future-version, and sensitive-data cases.\n\nTool rendering should be schema-driven and resilient to unknown tools. The UI\nmust not trust raw tool output as display-ready data.\n\n## Layers\n\n1. Message container: owns message grouping and association between tool call\n   metadata and tool output.\n2. Generic tool renderer: parses common metadata, displays status, and chooses a\n   specialized renderer when one is available.\n3. Specialized renderer: renders a known tool result schema.\n4. Fallback renderer: safely displays unknown JSON, text, or parse failures.\n\n## Structured Result Shape\n\nUse a generic shape that can be specialized:\n\n```ts\ntype ToolResult<TStatus extends string, TData = unknown> = {\n  schemaVersion: string;\n  tool: string;\n  status: TStatus;\n  data?: TData;\n  summary?: string;\n  errorCode?: string;\n};\n```\n\nThe frontend parser should accept `unknown` or raw message content, validate the\nminimum fields, and return a typed result or `undefined`.\n\n## Status Mapping\n\nMap tool status through a closed display status union:\n\n```ts\ntype ToolDisplayStatus =\n  | 'running'\n  | 'success'\n  | 'needs_input'\n  | 'not_found'\n  | 'denied'\n  | 'error'\n  | 'timeout'\n  | 'cancelled'\n  | 'unknown';\n```\n\nUse a single `Record<ToolDisplayStatus, DisplayConfig>` for labels, icons,\ncolors, and ARIA text. Do not scatter status rendering across component\nbranches.\n\n## Safety Rules\n\n- Treat tool output as untrusted.\n- Never render raw HTML from tool output unless sanitized by a trusted policy.\n- Never expose stack traces, credentials, provider secrets, or raw internal\n  payloads.\n- Do not infer status from user-visible text.\n- Do not hardcode one tool result as the only rendering path.\n- Unknown tools must have a safe fallback.\n\n## Parser Rules\n\n- Validate `schemaVersion`, `tool`, and `status`.\n- Preserve unknown fields for diagnostics only when safe.\n- Be forward compatible with unknown minor schema versions.\n- Provide unknown-status fallback.\n- Keep type assertions behind runtime checks.\n\n## Verification\n\nTest known structured results, unknown tool results, malformed JSON, plain text\noutput, unknown status, future schema versions, error envelope rendering, and\nsensitive field redaction.\n","tagline":"Design and review structured tool-result rendering.
