From 941ed7b934c75be8bb02565861db0f95badb758c Mon Sep 17 00:00:00 2001 From: Sebastian Braun Date: Fri, 28 Aug 2026 16:25:44 +0200 Subject: [PATCH 1/9] feat(agent): add hybrid BM25 search_wiki tool to query/chat agent Adds a dependency-free BM25 full-text index (openkb/fulltext_index.py) over concepts/entities/summaries pages, exposed as a new search_wiki tool alongside index.md-driven navigation in build_query_agent. Additive hybrid retrieval: surfaces pages whose one-line index summary omits a buried detail, without replacing existing navigation.

Sebastian Braun Date: Fri, 11 Sep 2026 11:47:17 +0200 Subject: [PATCH 3/9] feat(cli,agent): expose tiered search + taxonomy via CLI and wire into query/chat agent - cli.py: new 'openkb list-taxonomy [--kind concept|entity] [--json]' and 'openkb search [--scope briefs,summaries,sources] [--top-k N] [--json]' commands. - agent/tools.py: search_wiki now searches the new tiered briefs/summaries/sources index instead of the old combined concepts+entities+summaries index (concepts/entities move to the new list_taxonomy tool - semantic browsing, not keyword search); new list_taxonomy() text-formatting wrapper over list_taxonomy_items(). - agent/query.py (+ chat.py via tool inheritance): wires list_taxonomy and the retiered search_wiki in as agent tools; search strategy instructions updated to browse taxonomy first, then use scope-restricted search_wiki as a keyword fallback. - README.md: updated hybrid-retrieval paragraph and command table. - Intentional behavior change to agent.tools.search_wiki (scope param, concepts/entities out of scope, output grouped by tier) - safe since #234/#259, which introduced it, are not yet merged upstream; existing tests updated to the new contract. --- README.md | 4 +- openkb/agent/query.py | 74 ++++++++++++++++------- openkb/agent/tools.py | 83 ++++++++++++++++++++------ openkb/cli.py | 122

From b0278a5ccadb4ff1fb132ae137793a8092dd7b77 Mon Sep 17 00:00:00 2001 From: Sebastian Braun Date: Fri, 11 Sep 2026 14:30:00 +0200 Subject: [PATCH 6/9] feat(agent): add list_documents + unified get_content, explorations search tier MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit - agent/tools.py: get_taxonomy_item, read_wiki_file, get_wiki_page_content were four differently-shaped ways to read wiki content (slug+kind vs. path vs. doc_name+pages). Replace with a single get_content(slug, wiki_root, kind=None, pages=None) covering all seven content kinds (concept/entity/summary/exploration/source/report/index). kind=None fans out and returns one ContentEntry per match (mirrors list_taxonomy_items' kind=None semantics) instead of a first-match-wins precedence that would silently drop e.g. a source when a summary shares its slug. - read_wiki_file/get_wiki_page_content (already released, predate this branch) now delegate to get_content — kept for backward compatibility, existing tests unchanged. get_taxonomy_item is removed (unreleased, no callers outside its own tests). - New DocumentItem/list_documents (summaries + explorations), mirroring TaxonomyItem/list_taxonomy_items for a different pair of kinds. - New get_kb_status/KbStatus: structured KB counts (basis for a future MCP get_status tool), without pulling in cli.py's heavier import chain. - fulltext_index.py: add an explorations BM25 tier (TIERED_SCOPES now briefs/summaries/sources/explorations) — its own tier, not merged into summaries, so a hit stays labeled as a saved answer vs. a document summary. - Split agent/tools.py into agent/tools.py + new agent/content.py (tools.py re-exports for backward compatibility) to stay under the 800-line module gate (tests/test_file_size.py) after these additions. - Tests: tests/test_agent_tools.py (get_content across all kinds/error paths, list_documents, get_kb_status), tests/test_fulltext_index.py (explorations tier).

openkb list-documents [--kind summary|exploration] [--json]: new command mirroring openkb list-taxonomy, exposing the Core PR's list_documents. - openkb search --scope gains 'explorations' (TieredWikiSearch's 4th tier). - openkb list (print_list): deprecated in its help text in favor of list-taxonomy/list-documents; its Summaries/Concepts/Entities sections now call list_documents/list_taxonomy_items internally instead of duplicating directory-glob logic (Documents-registry-table and Reports listing stay as their own logic — they don't map onto the 5/7-kind content model). Output format unchanged for existing scripts. - agent/query.py: new list_documents tool (mirrors list_taxonomy's browse-list style) registered on the query agent — and therefore also the chat agent, which builds on top of it. Instructions updated to recognize an explorations search hit as a previously-saved answer, distinct from a summaries/sources hit, and to check list_documents before re-synthesizing an answer that may already exist. Deferred (not part of this PR, see plan): replacing the internal read_file/ get_page_content tools with the unified get_content — a separate, higher-risk change to an already-productive agent, to be assessed on its own. - tests/test_query.py: tool count/name assertions updated for the new list_documents tool.

It always returns a list, even for a single match, and +auto-detects whether a `source` is short or a paginated PageIndex +document (only the latter needs `pages`). | Goal | Action | |---|---| -| Read a concept page | read the file at `/wiki/concepts/.md` | -| Answer "who/what is X" about a named thing | read `/wiki/entities/.md` | -| Read a document's summary | read `/wiki/summaries/.md` | -| Read a short doc's full text | read `/wiki/sources/.md` | -| Read a long doc's specific page | shell: `jq '.[N-1]' /wiki/sources/.json` (N = 1-indexed PDF page; `.[0]` is page 1) | -| Search summaries/sources for a term (MCP available) | call `search_wiki` (optionally `scope: ["briefs"\|"summaries"\|"sources"]`) — tiered BM25, never covers concepts/entities (use `list_taxonomy` above for those) | -| Search summaries/sources for a term (no MCP, shell available) | shell: `openkb search "" [--scope briefs,summaries,sources] [--json]` | +| Read a concept page | read the file at `/wiki/concepts/.md`, or `get_content(slug, kind="concept")` | +| Answer "who/what is X" about a named thing | read `/wiki/entities/.md`, or `get_content(slug, kind="entity")` | +| Read a document's summary | read `/wiki/summaries/.md`, or `get_content(doc, kind="summary")` | +| Read a saved exploration (past query answer) | read `/wiki/explorations/.md`, or `get_content(slug, kind="exploration")` | +| Read a short doc's full text | read `/wiki/sources/.md`, or `get_content(doc, kind="source")` | +| Read a long doc's specific page | shell: `jq '.[N-1]' /wiki/sources/.json` (N = 1-indexed PDF page; `.[0]` is page 1), or `get_content(doc, kind="source", pages="N")` | +| Search summaries/sources/explorations for a term (MCP available) | call `search_wiki` (optionally `scope: ["briefs"\|"summaries"\|"sources"\|"explorations"]`) — tiered BM25, never covers concepts/entities (use `list_taxonomy` above for those) | +| Search summaries/sources/explorations for a term (no MCP, shell available) | shell: `openkb search "" [--scope briefs,summaries,sources,explorations] [--json]` | | Find an exact phrase (no MCP, no `openkb` CLI) | search `/wiki/` for `` (e.g. `grep -r`) — last resort, see note below | -| Follow a `[[wikilink]]` | read the linked path under `/wiki/` | +| Follow a `[[wikilink]]` | read the linked path under `/wiki/`, or `get_content` with the kind implied by its directory | | Synthesize an answer across many sources (LLM cost — last resort) | shell: `openkb query ""` | Prefer `search_wiki`/`openkb search` over `grep` whenever either is -available: both rank hits by BM25 relevance across three independent +available: both rank hits by BM25 relevance across four independent tiers (one-line summary briefs, full summary bodies, raw sources — including per-page indexing of long PageIndex documents, so a hit's `locator` names the exact page to fetch next with -`get_page_content`/`jq`) instead of raw occurrence count. `grep` has no -relevance ranking, so a document that happens to repeat a generic word -many times (e.g. "case" in unrelated "in case of error" phrasing) can -outrank the one actually about the topic — fall back to it only when -neither the MCP server nor the CLI is reachable. +`get_page_content`/`get_content`/`jq` — and saved exploration answers) +instead of raw occurrence count. `grep` has no relevance ranking, so a +document that happens to repeat a generic word many times (e.g. "case" +in unrelated "in case of error" phrasing) can outrank the one actually +about the topic — fall back to it only when neither the MCP server nor +the CLI is reachable.
