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.

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 | $0.00044 | $0.00881 |
| Opus 5 | $0.00022 | $0.00441 |
| Sonnet 5 | $0.00009 | $0.00176 |
| Haiku 4.5 | $0.00004 | $0.00088 |
Grade A, and why
al-code-review 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.
How it starts
The opening of the file, as written. The whole thing — 70 lines — stays where its author put it; the contents beside it link to each section on GitHub.
AL code review
This is BCQuality's host-native adapter for standalone plugin installations. It is not a BCQuality action skill and contains no review or routing policy. Its only responsibility is to translate the caller's request into an Entry task context and execute the resulting dispatch.
Execute
- Resolve
PLUGIN_ROOTto the directory containing this plugin's rootplugin.json. This file isPLUGIN_ROOT/skills/al-code-review/SKILL.md; when the host does not expose the plugin root, resolve it two levels above this file. - Build the
task-contextrequired byPLUGIN_ROOT/skills/entry.md:- Copy the caller's actual request verbatim into
goal; do not replace a focused request such as "review performance" with a generic full-review goal. - Set
inputs-availableto the inputs actually available to the review, normallypr-difffor changes orfile-pathfor one file. - Set
technologies: [al]when the input is known to be AL. - Pass
bc-version,countries, andapplication-areaonly when supplied or reliably determined. - If
BCQUALITY_ENABLED_LAYERSis set, split its comma-separated value and pass the trimmed, non-empty entries asenabled-layers; otherwise omit the field and let Entry apply its default. - If
BCQUALITY_DISABLED_SKILLSis set, split its comma-separated value and pass the trimmed, non-empty entries asdisabled-skills; otherwise omit the field.
- Copy the caller's actual request verbatim into
- Read and execute
PLUGIN_ROOT/skills/entry.mdexactly as written, including its Preparation step. Entry is authoritative for index freshness, routing, defaults, and failure behavior; this adapter must not duplicate or weaken those rules. Entry is written for a checkout whose root is the current directory, so resolve every repo-relative path it names againstPLUGIN_ROOTrather than the caller's working directory, which is the user's own project. In particular, run Preparation's index build aspwsh PLUGIN_ROOT/tools/Build-KnowledgeIndex.ps1: the generator resolves its own root and writesPLUGIN_ROOT/knowledge-index.json, which is not shipped and is therefore absent on a fresh install. Ifpwshis unavailable or the build fails, continue — READ falls back to path-based discovery — but do not treat a failed build as a failed review. - Follow Entry's How the agent uses the dispatch instructions. Invoke only
the returned action skills, pass each dispatch entry's exact input subset,
and read
PLUGIN_ROOT/skills/read.mdandPLUGIN_ROOT/skills/do.mdon demand. When a dispatched super-skill requests isolated leaf execution and the host supports child contexts, use them. - Return each dispatched action skill's findings report unchanged. If Entry
returns
no-matchorfailed, return its dispatch record unchanged.
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.

al-code-review is a skill published in the GitHub repository microsoft/BCQuality (206 stars, last pushed yesterday), licensed MIT. It adds 44 tokens to every session and 881 once invoked, about $0.0002 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 2026-09-03.
