bc

A command that delegates Business Central development work to a specialized assistant. Business Central is Microsoft's business-management software, and AL is its programming language.

In plain words
What is it for?
Use it to send an AL development task to the bc-developer assistant, which can look up Business Central objects and compile the result.
Why use it?
It removes the need to manually coordinate the Business Central tools, object lookup, compilation, and diagnostic reporting.

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.

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

bc 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 2d 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.

What it actually says

Delegate this task to the bc-developer subagent:

$ARGUMENTS

The subagent knows the BC toolchain (almcp MCP server, bc-symbols MCP server, BcContainerHelper) and will look up any standard or third-party BC objects via bc-symbols before editing code. It will compile via al_build and report structured diagnostics.

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.

bc is a command published in the GitHub repository loacher-solution/bc-agent-plugin (2 stars, last pushed 4mo ago), licensed MIT. It adds 15 tokens to every session and 94 once invoked, about $0.0001 per session on Opus 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 2026-08-31.
