About this software

knowledge 0.0.15

Three new ways to see what the knowledge base holds, and one to check that it agrees with its JSONL dump. The decisions are DR-0051 to DR-0055. Everything was written and tested red first. The new verbs were checked by running the v0.0.14 build beside the new one, on a copy of the real workspace, over 415 commands in plain and --json mode: the only changed exit codes were the two new verbs’ own, and nothing exited 70. That comparison was made before the two fixes described last, which change behaviour on purpose.

kb concept show NAME prints one concept’s description and identifier, what links to it (projects, observations, records, document sections) with the full counts, and up to --limit items of each kind, newest first (default 10; --limit 0 gives counts only). The name matches exactly, as concept delete does, and a miss offers a case variant. It replaces the raw sqlite3 joins that judging a concept suggest candidate used to need.

kb concept recall finds the concepts named in some text (arguments, or stdin with -) and lists the observations, records and document sections linked to them, ranked by how many of those concepts each matches and then by recency, with the concepts each hit matched. --concept NAME,... names concepts directly, --project restricts the hits, --limit caps them. Text that matches no concept exits 1. Harvey’s memory recall uses the same library call.

kb record fuzzy-tag --project NAME reports near-miss spellings of known concepts in decision records (a detoast for the concept toast), which exact matching never links, and the tags: line that would link them. It writes nothing by default. --write adds the concept to the tags: of proposed records only, changes nothing else in the file, and never touches an accepted record; kb ingest then links the tags. --concept NAME,... widens the named concepts to forms that contain the name.

kb check-db [--jsonl FILE] compares the database with the JSONL dump beside it by full content, never by file time, and recommends kb import, kb export, or both. It is read-only and exits 0 in sync and 1 otherwise. There are no tombstones, so rows only in the dump may be rows deleted here on purpose, and the report says so.

The detection half of kb merge is now a read-only library pipeline shared with check-db; merge’s output is unchanged.

Two fixes. kb import no longer rewrites an observation kind outside note, finding, decision, question and hypothesis to note (DR-0054): it keeps the kind and prints a warning: line, or a Warnings list under --json, and still exits 0. The rewrite made kb check-db report a false divergence, and following its advice to import and export would have written the changed kind into the authoritative dump. kb project add (DR-0055) no longer prints “added” for a name that already exists: it exits 1 with already exists, as project rename does, and writes nothing (it used to move updated_at, which merge uses to pick a winner, and drop the status and description you gave it). A --status typed after NAME is a usage error that says the flag goes before NAME, where it used to become part of the description; -- before NAME keeps a flag-looking word as text.

Upgrading: two things that worked change. kb project add on an existing name now exits 1, where it exited 0, so a script that repeated the call must expect that; the library’s AddProject still returns the existing id. And a record file that does not parse now exits 65 (wrong content) from record set-status, record supersede and project rename (the verbs that read a record file to edit it) where it exited 2, since the file’s content is what is wrong, not the command line. Library additions: ConceptDetail, RecallByText, RecallByNames, RecordFuzzyReport, AddRecordTags, CompareToJSONL, DiffDatabases, PrepareMergeScratch and DetectIdentityIssues; ImportTableSummary gains a Warnings field.

Authors

A standalone SQLite3-backed knowledge base for tracking projects, observations, concepts, decision records, and narrative documents across independent experiments in the rsdoiel/Laboratory workspace. Extracted from the harvey terminal agent’s knowledge.go, this module provides a typed CRUD API (Open, AddProject, AddObservationWithSource, AddConceptWithIdentifier, Search, and related methods) plus UUID-based row identity and a SQL/ATTACH-based cross-machine merge tool, so other experiments and language-model harnesses can read and write structured observations directly instead of raw sqlite3 CLI inserts. Ships cmd/kb, a single “kb VERB ARGS” binary (matching the git/go command model) covering the full API with both human-readable and –json output, a merge verb for reconciling two databases that drifted independently, and a read-only interactive TUI browser for exploring projects, observations, and concepts. It also indexes Decision Records – episode-scoped Markdown files with YAML frontmatter, kept in a project’s decisions/ directory – as first-class rows, so the reasoning behind a decision is retrievable rather than living only in files the knowledge base never reads. Inline [[wikilink]] tagging and frontmatter tags/keywords resolve to concepts at ingest time (records and documents alike), an embedder-free RecallByConceptNames/MatchConceptNames pair gives small/CPU-only models a cheap concept-based retrieval path ahead of any vector RAG, and a documents/document_sections schema ingests narratives and articles (Markdown, Fountain, plain text) at graduated abstraction levels – a document-level gist plus per-section summaries, each going through an explicit human review step before being trusted as searchable content.
