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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00134 | $0.11083 |
| Opus 5 | $0.00067 | $0.05542 |
| Sonnet 5 | $0.00027 | $0.02217 |
| Haiku 4.5 | $0.00013 | $0.01108 |
Grade B, and why
context-onboarding scanned grade B 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 9d 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.
Reads agent configuration directoriesmediumAgent snooping
.claude/, .codex/, .gemini/ hold keys, settings and other credentials a mod has no legitimate need for.
- **Yes, multi-repo** — mirror the allowlist to `~/.claude/settings.json` so cross-repo runs don't stall How it starts
The opening of the file, as written. The whole thing — 784 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Context Onboarding
Goal
Working context system, user-approved, in under 30 minutes.
Claude does the drafting. The user reviews and corrects. No questionnaires, no choices to make.
How It Works
Claude asks ONE direct question upfront — "what kind of project is this?" — and uses the answer to pick the right template + pattern doc. After that, Claude figures out the rest from what the user says and what's in the repo. No long path-chooser; just one gate that routes scaffolding correctly.
Signals → What to do
| What you see | What you do |
|---|---|
| User shares a URL, pitch deck, or describes their business | Gather from those sources, ask 2-3 follow-ups if needed |
| Repo already has docs/, README, markdown files with business content | Scan the repo, map what exists |
User drops files in docs/_inbox/ |
Read those files — but STILL ask if there's more before proceeding |
| User has MCP connectors (Google Drive, Notion, etc.) | Ask what to look at — don't fetch everything |
| User just says "help me get started" or "what do I do next?" | Quick-check repo, check for MCP connectors, then ask where their knowledge lives |
| Mix of the above | Combine all available sources |
Step 0: Identify Project Type + Discover Sources
Two short AskUserQuestion gates, in order: what kind of project this is (0a), then where the knowledge lives (0b). Pre-fill both from what you can see before asking — the user confirms or overrides.
0-pre. CLAUDE.md self-heal (silent)
Before anything else, run once per onboarding session to make sure the BCOS-managed instructions are present in CLAUDE.md. This catches the git clone-without-install.sh case: if CLAUDE.md exists but lacks the <!-- BCOS:CORE:START --> / <!-- BCOS:CORE:END --> markers, the framework section is missing or unstructured. The helper below splices it in.

--source .claude/bcos-claude-reference.md \

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.

context-onboarding is a skill published in the GitHub repository walm00/business-context-os (21 stars, last pushed 3mo ago), licensed MIT. It adds 134 tokens to every session and 11,083 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it B with 1 finding (reads agent configuration directories). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
