microsoft/BCQuality is a structured knowledge base and skills library for Microsoft Business Central development. It records Business Central-specific rules and platform behaviors that coding agents or developers might otherwise get wrong. The catalogue entries provide the agents and skill that consume this guidance.
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.

A badge with what this costs and how it scanned, read live from this page, so it follows the numbers instead of freezing them. Markdown for a README, HTML for a documentation site or a project page.

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 | $0.00000 | $0.00248 |
| Opus 5 | $0.00000 | $0.00124 |
| Sonnet 5 | $0.00000 | $0.00050 |
| Haiku 4.5 | $0.00000 | $0.00025 |
Grade A, and why
reapply-resource-instructions-on-upgrade 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
Reapply resource instructions to existing agent instances on upgrade
Description
Static instructions stored as an app resource are copied onto an instance only when you call SetInstructions. Shipping a new Instructions.txt in version 2.0 does not update agents created under 1.0. Models change the resource and assume running instances pick it up.
Best Practice
In the upgrade codeunit, find existing instances of your metadata provider and call SetInstructions again with NavApp.GetResourceAsText. Guard with an upgrade tag so the rewrite runs once per version that changes the file.
See sample: reapply-resource-instructions-on-upgrade.good.al.
Anti Pattern
Editing only the resource file, or calling SetInstructions solely from the first-time setup path. Detection signal: instruction resource in resourceFolders with no upgrade procedure that re-applies it.
See sample: reapply-resource-instructions-on-upgrade.bad.al.
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.

reapply-resource-instructions-on-upgrade is an agent published in the GitHub repository microsoft/BCQuality (206 stars, last pushed yesterday), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 248 tokens. 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 2026-09-03.
