Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00041 | $0.03623 |
| Opus 5 | $0.00020 | $0.01811 |
| Sonnet 5 | $0.00008 | $0.00725 |
| Haiku 4.5 | $0.00004 | $0.00362 |
Grade A, and why
businesscentral scanned grade A 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 12d 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
Node.js `fetch()` also doesn't work in the sandbox — use `curl` directly for token exchange. How it starts
The opening of the file, as written. The whole thing — 444 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Business Central Skill for Claude Code
Interact with Microsoft Dynamics 365 Business Central via the REST API using bc-cli.
Prerequisites
- Node.js 18+ installed
- bc-cli installed from this skill's directory:
# From skill directory npm link # Or run directly node <skill-path>/bin/bc-cli.mjs <command>
No Azure AD setup needed — a default app registration is included.
Binary location: bc-cli is at ../../bin/bc-cli.mjs relative to this SKILL.md file. In Cowork, find it at <plugin-path>/bin/bc-cli.mjs.
Authentication
Step 1: Check if already authenticated
bc-cli status
If status shows "Active", you're ready — skip to "Operation Safety Levels".
Step 2: Login
Claude Code (local machine — no sandbox)
Just run:
bc-cli login
This will:
- Open your browser to the Microsoft login page
- You sign in with your Microsoft/Business Central account
- Token is saved automatically with auto-refresh
- Tenant and environment are auto-detected
That's it. No Client ID, no Tenant ID, no environment to configure — everything is automatic.
Claude Cowork (sandboxed environment)
IMPORTANT — Domain allowlist setup (MUST do before anything else):
The user MUST add these domains to the Cowork network allowlist:
*.microsoftonline.com(Microsoft authentication)*.businesscentral.dynamics.com(Business Central API)
How: In Cowork, go to Settings > Capabilities > Domain allowlist > Additional allowed domains and add both domains. Without this, all API calls will fail.
In Cowork, bc-cli login cannot open the user's browser because the sandbox is isolated.
Node.js fetch() also doesn't work in the sandbox — use curl directly for token exchange.
Step A — Generate the auth URL:
bc-cli login-url --port=33333
This outputs JSON with authorizeUrl, verifier, and redirectUri. Save the verifier — you'll need it in Step C.
Step B — Ask the user to authenticate:
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.
