kb-ingest-bulk

name: kb-ingest-bulk description: Parallel map-reduce bulk ingest for large source sets. Map phase dispatches read-only knowledge-extractor agents (≤N-wide, default Haiku) emitting per-source JSON extracts; Python routes extracts by target library file (fuzzy-merging new topics, pre-allocating new files, flagging oversized topics); reduce phase dispatches one agent-knowledge-updater per file (parallel, one writer per file); single shelf-index rebuild + one log.md entry. Resumable. Supersedes kb-ingest-batch. disable-model-invocation: false argument-hint: "<glob|dir|file-list> [--library ] [--parallel ] [--extractor-model ] [--size-threshold ] [--retry-failed] [--clean]"

Bulk Ingestion (map-reduce)

Load a large source set into the knowledge base in parallel. Four phases: map (parallel extract) → route (Python) → reduce (parallel synthesis, one writer per file) → finalize (one rebuild + one log entry).

Arguments

Preflight

1. Resolve library_path: if --library given, use it; else read CLAUDE.md ## Knowledge Base section. Derive shelf_index_path = <library>/_shelf-index.md, log_path = <library>/log.md, extracts_dir = <library>/.extracts.
2. Verify knowledge-extractor and agent-knowledge-updater agents are available.
3. Clamp --parallel to [1, 64].

Module bootstrap

Use this CLAUDE_PLUGIN_ROOT importlib loader block to import the sdlc_knowledge_base_scripts.kb_ingest_bulk helpers. It is self-contained — no other file needs to be opened.

import sys, os, importlib.util, json
PLUGIN_ROOT = os.environ.get('CLAUDE_PLUGIN_ROOT', '')
SCRIPTS = os.path.join(PLUGIN_ROOT, 'scripts')
INIT = os.path.join(SCRIPTS, '__init__.py')
if os.path.isfile(INIT) and 'sdlc_knowledge_base_scripts' not in sys.modules:
    spec = importlib.util.spec_from_file_location(
        'sdlc_knowledge_base_scripts', INIT, submodule_search_locations=[SCRIPTS])
    if spec and spec.loader:
        mod = importlib.util.module_from_spec(spec)
        sys.modules['sdlc_knowledge_base_scripts'] = mod

Phase 1 — Map (parallel ≤N)

1. discover_sources(<spec>) → source list; build_bulk_manifest(...) (merge prior manifest via load_manifest if present; retry_failed if --retry-failed); save_manifest.
2. For each pending source whose extract file does NOT already exist (resume skip): dispatch knowledge-extractor with format_extract_prompt(...), up to N concurrently (parallel Agent-tool calls). Capture each agent's JSON reply.
3. After each agent: persist_extract(extracts_dir, slug, json) then mark_source_extracted; on error/invalid-JSON mark_source_failed. save_manifest after each round.

Phase 2 — Route (Python, no agents)

4. Load all extract JSON files. Compute existing_files = set of *.md in the library (excluding _shelf-index.md, log.md, _index.md, and anything under raw/).
5. route = route_extracts(extracts, existing_files, size_threshold). Record each route.targets entry into manifest["targets"] as pending with source_count and is_new. Report route.oversized (skipped). save_manifest.

Phase 3 — Reduce (parallel ≤N, one writer per file)

6. For each pending target: dispatch ONE agent-knowledge-updater with format_reduce_prompt(ReduceDispatchRequest(...)), up to N concurrently. Exactly one agent per file — never two agents on the same file.
7. After each: mark_target_reduced (success) or mark_target_failed (error). save_manifest after each round.

Phase 4 — Finalize (once)

8. Rebuild the shelf-index once via build_shelf_index.main([library_path]).
9. write_log_entry(log_path, "## [<date>] ingest-bulk\n" + summarize_run(manifest, route.oversized)).
10. Print the summary table. If --clean, remove extracts_dir.

Exit / partial failure

A failed source drops out of routing; a failed target leaves its extracts on disk for --retry-failed. Report all failures + oversized topics. Non-zero exit only if nothing succeeded.
