Knowledge Base Statistics

Lightweight: This skill reads only index metadata (shelf-index + log.md). Inline execution is acceptable — no agent dispatch needed.

Surfaces library health metrics in a single markdown report.

Arguments

• --output <path> — Write report to a file instead of stdout
• --since <ISO-date> — Override the recent-activity window start date (default: 30 days ago)

Preflight

Read CLAUDE.md [Knowledge Base] section to resolve library_path (default library/) and shelf_index_path (default library/_shelf-index.md).

Steps

1. Resolve configuration

Extract library_path, shelf_index_path, and log_path (default library/log.md) from CLAUDE.md.

2. Run kb_stats.py

python3 -c "
import sys, os, importlib.util
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
        spec.loader.exec_module(mod)
from sdlc_knowledge_base_scripts.kb_stats import main
args = ['--library-path', '<library_path>',
        '--shelf-index-path', '<shelf_index_path>',
        '--log-path', '<log_path>']
# If --output <path> passed: args += ['--output', '<output_path>']
# If --since <date> passed:  args += ['--since', '<since_date>']
sys.exit(main(args))
"

3. Report results

Print the markdown report (5 sections). If --output was passed, confirm the file was written.

What this skill does NOT do

• Does not validate citations (kb-validate-citations does that)
• Does not detect contradictions (kb-lint does that)
• Does not query findings (kb-query does that)
• Does not invoke any agent

Errors

• Library directory not found — run /sdlc-knowledge-base:kb-init first
• No shelf-index — run /sdlc-knowledge-base:kb-rebuild-indexes first
