The chat component now accepts optional grounding props, listens for starter-chip prefill events, prepends invisible seed context only on the first fresh turn, shows a visible grounding chip, and forwards `toolsets` and `yolo` through the existing admin write path. The Knowledge Graph page now mounts a dedicated grounded chat wrapper that derives context from the active graph and reuses the existing Hermes hooks. The bridge layer validates the new chat options and appends `-t ` plus `--yolo -s graphify` as argv entries only. *** ## Deliverables ### Files Created | File | Purpose | Lines | | --------------------------------------------------------------------------------- | ------------------------------------------------------------------------------- | ----- | | `src/lib/knowledge-graph-hermes-grounding.ts` | Deterministic grounding helper for seed context, labels, and accents | \~92 | | `src/lib/__tests__/knowledge-graph-hermes-grounding.test.ts` | Helper coverage for seed text and fallback behavior | \~79 | | `src/components/knowledge-graph/knowledge-graph-grounded-chat.tsx` | Knowledge Graph chat wrapper wired to Hermes reads and writes | \~141 | | `src/components/knowledge-graph/__tests__/knowledge-graph-grounded-chat.test.tsx` | Wrapper coverage for graph state, demo/offline handling, and anchor composition | \~325 | ### Files Modified | File | Changes | | ------------------------------------------------------------------------ | ------------------------------------------------------------------------------------------ | | `src/components/hermes/chat/chat-types.ts` | Added grounding and send-option types | | `src/components/hermes/chat/index.ts` | Re-exported chat grounding types | | `src/components/hermes/chat/hermes-chat-tab.tsx` | Added prefill listener, first-turn seed prefix, grounding chip, and tool option forwarding | | `src/components/hermes/chat/__tests__/hermes-chat-tab.test.tsx` | Added prefill, grounding, seed, and resumed-thread coverage | | `src/hooks/use-hermes-admin.ts` | Serialized `toolsets` and `yolo` on the Hermes admin chat path | | `src/hooks/__tests__/use-hermes-admin.test.tsx` | Added payload serialization and abort coverage | | `scripts/lib/hermes-admin-bridge.ts` | Validated new chat options and appended graphify argv flags | | `scripts/lib/__tests__/hermes-admin-bridge.test.ts` | Added argv and fail-closed coverage | | `src/components/knowledge-graph/knowledge-graph-page.tsx` | Mounted the grounded chat wrapper in the page composition | | `src/components/knowledge-graph/__tests__/knowledge-graph-page.test.tsx` | Added anchor/composition coverage | *** ## Technical Decisions 1. **Keep grounding inside `HermesChatTab`**: The existing chat module already owns composer state, local messages, and write orchestration, so extending it avoided a second chat implementation. 2. **Treat seed context as server-only prompt input**: The user sees the grounding chip and their own prompt, but not the invisible graph seed text. 3. **Validate new bridge payload fields at the boundary**: `toolsets` and `yolo` remain optional and fail closed before spawn, and they are appended as argv entries only. *** ## Test Results | Metric | Value | | -------- | ----- | | Tests | 91 | | Passed | 91 | | Coverage | N/A | *** ## Lessons Learned 1. Prefill behavior is safest when handled as an explicit browser event with cleanup on unmount. 2. Grounded chat needs explicit fresh-turn detection so resumed sessions do not duplicate seed context. 3. Bridge validation should stay strict and boring; the safety boundary matters more than convenience. *** ## Future Considerations Items for future sessions: 1. Complete the remaining phase 26 homepage and documentation work. 2. Keep the Knowledge Graph grounding text aligned with any future graph path or registry changes. *** ## Session Statistics * **Tasks**: 22 completed * **Files Created**: 4 * **Files Modified**: 10 * **Tests Added**: 91 * **Blockers**: 0 resolved --- # Agent Instructions This documentation is published with GitBook.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://ai-os-and-trend-finder.gitbook.io/ai-os-and-trend-finder-docs/.spec_system/archive/sessions/phase26-session07-hermes-chat-grounding-graph-toolset/implementation_summary.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
