business-context-os: Skill for Claude Code

.claude/skills/context-audit/SKILL.md

context-audit is a skill for Claude Code from walm00/business-context-os. It costs 115 tokens per session (2,483 once invoked), scanned A, original, MIT.

A review tool for a structured context system called CLEAR. It checks documents for duplication, ownership conflicts, boundary problems, naming issues, and inconsistent structure.

In plain words
What is it for?
Use it to inspect selected context areas, prepare restructuring work, find duplicate information, and produce prioritised recommendations. It reports problems but does not fix them.
Why use it?
It reveals where information is repeated, stored in the wrong place, or organised inconsistently before those problems spread.

Skill for Claude Code

Written for Claude Code: allowed-tools in frontmatter. Also seen: reads .claude/ paths; names the AskUserQuestion tool.

This is walm00/business-context-os's own configuration. It tells Claude Code how to work on business-context-os itself, so it is not a mod to install elsewhere. Copy it as a starting point and replace the rules that are about this project. Everything business-context-os configures →

Needs its repository: it runs a file that does not travel with it, so clone the repository first. The line is python .claude/scripts/build_document_index.py.

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

context-audit 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 8d 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.

Context Audit

Purpose

This skill IS:

  • Auditing context data points for CLEAR compliance
  • Finding duplication and ownership conflicts across data points
  • Identifying boundary violations between context areas
  • Enforcing consistency in naming, format, and structure
  • Providing prioritized findings with improvement recommendations

This skill IS NOT:

  • Making changes to context (audit only -- findings guide manual fixes)
  • A fix-it tool (this finds problems, you fix them based on findings)
  • Checking markdown syntax (use doc-lint for that)
  • Planning new work (use clear-planner for that)


Instructions

Step 1: Define Audit Scope

Pre-read (cheap, do this first): if docs/document-index.md exists, read it before asking the scope question. It gives you the canonical inventory of active data points by cluster, ownership, and last-updated date — enough to suggest a smart default scope (e.g., "you have 14 data points across 3 clusters; 4 haven't been touched in 90+ days — audit those?") instead of asking blind. If absent, fall back to the question below directly.

If not specified, use the AskUserQuestion tool:

  • Question: "What should I audit?"
  • Options:
    • Specific area (e.g., competitive intelligence data points)
    • Full architecture (all active data points — comprehensive)
    • Recent changes (only docs modified recently)
    • Cross-cutting concern (e.g., all pricing-related data points across clusters)

Step 2: Gather and Check Metadata

Context window strategy: For scopes with 20+ documents, delegate the metadata scanning to an explore agent. Keep the main window for CLEAR analysis (Step 3).

# For large scopes:
Agent (Explore): "Read all .md files in [scope]. Skip dot-prefixed files
(.session-diary.md, .wake-up-context.md, .onboarding-checklist.md) — these are
conventions, not managed data points. For each remaining file, extract YAML
frontmatter and check: all 7 required fields present? status valid? last-updated
within 90 days (180 days for _planned/)? Return a validation table."

Changes

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.
