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-citationsdoes that) - Does not detect contradictions (
kb-lintdoes that) - Does not query findings (
kb-querydoes that) - Does not invoke any agent
Errors
