business-context-os: Instructions file for Claude Code

CLAUDE.md

business-context-os CLAUDE.md is an instructions file for Claude Code from walm00/business-context-os. It costs 3,726 tokens per session, scanned C, original, MIT.

An instruction guide for CLEAR Context OS, a system for organizing and retrieving business knowledge for an AI assistant. It explains how to load context, start a session, and route new information.

In plain words
What is it for?
Starting context-aware sessions, finding relevant business information, handling new content, and deciding when larger tasks need a plan.
Why use it?
It reduces answers based on guesswork by requiring the assistant to consult the project’s stored context for non-trivial work.

Instructions file for Claude Code

Written for Claude Code: $CLAUDE_PROJECT_DIR variable. Also seen: reads .claude/ paths; mentions CLAUDE.md; 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 →

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 C, and why

business-context-os CLAUDE.md scanned grade C with 1 finding 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.

Hidden instructionshighPrompt injection

Directives inside HTML comments, invisible characters or bidirectional overrides are read by the model and not by the person reviewing the file.

<!-- Anything outside the BCOS:CORE markers below is yours — repo identity, project notes, plugin instructions, team conventions. Add it above or below the CORE block. BCOS only manages what's between the CORE markers. -

How to Work

Never answer cold. Every non-trivial answer leans on context — use the structure to find it cheaply.

  • Trivial: math, syntax, "list files", obvious one-liners, framework / skill / CLI questions — answer directly.
  • Anything else (questions, edits, plans, decisions — about the business, the docs, processes, decisions, anything BCOS knows) — load context first via the Retrieval Playbook below. Don't grep when there's an index. Don't paraphrase a data point you haven't read. Don't restate from training when the canonical answer is one read away.
  • Small changes (1-3 files) — think briefly, execute.
  • Significant changes — use clear-planner skill.
  • New content arriving — use context-ingest to route it.
  • When in doubt — ask: "Should I just do this, or plan it out first?"

Session Start

Read these files at the start of any context-related work:

  1. docs/.wake-up-context.md — Compressed snapshot (~200 tokens). Read FIRST for instant orientation. Auto-generated by python .claude/scripts/generate_wakeup_context.py.
  2. docs/.onboarding-checklist.md — Onboarding progress. Mention the next unchecked item once (don't nag). When all items are checked, delete this file and remove this line from CLAUDE.md.
  3. docs/.session-diary.md — Recent session notes for continuity. Append an entry at session end.

Drill into the heavier orientation docs when the task calls for it — the wake-up snapshot lists task-driven pointers in its "Drill into when relevant" block. Quick reference:

  • docs/document-index.md — read before adding or editing a data point (find the owner, avoid duplication)
  • docs/current-state.md — read for strategy / "what's true right now" questions
  • docs/table-of-context.md — read for architecture-level navigation

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.
