kb-stats

kb-stats is a skill for Claude Code from SteveGJones/ai-first-sdlc-practices. It costs 44 tokens per session (644 once invoked), scanned A, original, MIT.

A read-only statistics report for a knowledge base, meaning a stored collection of documents and notes. It reads the knowledge base index and activity log to summarize its contents and recent changes.

In plain words
What is it for?
Use it to report inventory, distribution by layer and subject, recent activity, and stale knowledge-base entries.
Why use it?
It gives a quick view of the library without changing its files or sending work to other agents. It also highlights uneven coverage and outdated material.

Skill for Claude Code

Written for Claude Code: disable-model-invocation in frontmatter. Also seen: mentions CLAUDE.md.

Runs only inside its plugin — its command needs a path that Claude Code sets for a plugin’s own hooks and for nothing else. Install the plugin, not this.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

kb-stats scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 1mo ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.

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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

kb-stats is a skill published in the GitHub repository SteveGJones/ai-first-sdlc-practices (41 stars, last pushed 15d ago), licensed MIT. It adds 44 tokens to every session and 644 once invoked, about $0.0002 per session on Opus 5.5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
