Michael Dieringer faa0bceb86 Fix remaining correctness issues from Jesper's 2026-09-15 re-review
- dimension-management-wiring: SaveDefaultDim's third argument is the
  shortcut dimension number (1-8), not the field's AL field ID; the
  fixture passed FieldNo(...) = 10. GetDefaultDimID's InheritFromDimSetID
  must be 0 when recomputing after the linking record changes, not the
  document's existing Dimension Set ID (which would retain the previous
  customer's leftover dimensions). Verified against
  DimensionManagement.Codeunit.al and BankDepositHeader.Table.al in the
  BCApps reference clone.
- check-post-line-batch-pattern: "Post Line writes exactly one line to
  the ledger" overclaimed - Gen. Jnl.-Post Line alone calls InsertGLEntry
  from a dozen call sites (balancing entry, VAT, currency rounding,
  deferrals) and can write several G/L Entries per journal line.
  Reworded to "posts exactly one journal line" and softened the
  "distinct, non-overlapping responsibilities" absolute.
- namespace-must-be-verified-from-source.bad.al: dropped the "resolves
  in a local build, fails in VS Code" comment (taught an inherent
  compiler/language-server disagreement that isn't real); reframed as
  stale/cached symbols, matching the prose fix already made.
- file-datatype-saas.good.al: replaced the deprecated 5-argument
  UploadIntoStream overload with the current 2-argument one, and
  actually staged through TempBlob as the article's own Best Practice
  instructs (the declared TempBlob variable was previously unused).
- test-data-must-be-random-and-complete: no longer treats a
  short-but-valid value as defective merely for being "underfilled" -
  AL field lengths are maxima, not minimums. Scoped to missing values
  or a scenario with an explicit length/format requirement (e.g. a
  truncation test). Updated the al-testing-review.md routing cue to
  match.
- stored-derived-fields-must-not-be-exposed-directly: stopped mandating
  source-field exposure as part of the core pattern: the good fixture
  exposed only one of the derived value's two inputs (Hours Used, not
  Budgeted Hours), making the claimed "so the consumer can verify it"
  impossible. Reframed as an optional, all-or-nothing addition and
  fixed the fixture to expose both inputs.

Rebased onto upstream/main to resolve conflicts in
al-breaking-changes-review.md, al-data-modeling-review.md,
al-performance-review.md, and al-style-review.md against merged PRs
#148 and #153; all sides' worklist tokens/cues retained.

BC Quality - Don’t teach one agent. Teach the ecosystem. 🤝

Quality skills and knowledge that help AI tools make better Business Central development decisions: catch BC-specific defects, avoid misleading advice, and explain findings with references you can read.

BCQuality contains knowledge and reusable skills, not agents or a Business Central extension. Your host supplies the agent. You can install the content as a plugin, use it from another integration, or browse the knowledge directly.

Quick start

The walkthrough below uses GitHub Copilot CLI in a terminal, not the Copilot Chat panel in VS Code. First install Copilot CLI and sign in. Your account and organization policy must allow its use. You do not need to clone BCQuality, build a runner, or deploy an app to Business Central for this source-review example.

Standalone plugin installation

Run these commands in your terminal:

copilot plugin install microsoft/BCQuality
copilot plugin list

The list should include bcquality. The plugin currently exposes the al-code-review skill. Installation and skill discovery are the general pattern; reviewing an app is one example of using it.

Example: Review a complete app folder

Start a new CLI session in your own app folder, replacing the example path:

cd "C:\Repos\MyBusinessCentralApp"
copilot

Approve access only to a project you trust, then ask:

Use the installed al-code-review skill to review the complete Business Central app in this folder without changing my source files. Return the complete BCQuality findings report.

The folder should contain app.json and your AL source; it does not need to be a Git repository. On macOS or Linux, use your app's local path instead.

Expect a report for each selected review, with findings, source locations, severity, confidence, and references to the relevant guidance. Some hosts show the structured JSON directly. completed with no findings means nothing was flagged in that review's scope; partial or failed is not a clean result. See reading your results.

PowerShell 7 (pwsh) is recommended for fast knowledge discovery. If it is unavailable, the review can still discover knowledge by reading the folders.

Scope

Today's curated content covers technical AL code review and a focused Supply Chain Management (SCM) functional domain. It augments the agent's judgment; it is not an exhaustive BC manual or a substitute for compilation, analyzers, tests, or human review. See coverage and limits for the available domains and the difference between a folder review and a comparison. Mechanical issues already enforced by the AL compiler or standard analyzers are intentionally left to those deterministic tools rather than duplicated here.

The SCM domain covers selected inventory, costing, reservation, tracking, and warehouse/posting workflows, not exhaustive supply chain validation. Broader functional coverage such as Finance, Manufacturing, Jobs, and Service, and technologies such as PowerShell, pipelines, and Power Platform, remain valid future scope, not current coverage claims.

What's in this repo

Knowledge articles cover one concern each. Skills tell an agent how to find and apply the relevant knowledge. Both live in three layers:

Layer Purpose
Microsoft Microsoft-endorsed skills and their knowledge.
Community Community-owned skills and their knowledge.
Custom Organization-specific additions and overrides in your own fork.

All three are enabled by default; Custom is empty upstream. You do not need to configure layers to get started.

Versioning

Update the installed plugin from your terminal, then start a new session:

copilot plugin update bcquality

Plugin versions and content-release tags are different. For reproducible runs and organization forks, see updates and versions.

What belongs here

Knowledge belongs here when it prevents a BC-specific mistake an otherwise capable agent would make, including false-positive findings. BC facts belong in knowledge articles, not skill instructions. See the admission test and examples.

Contributing

Partners are welcome to contribute to the layer that owns the domain, regardless of affiliation. Start with the contribution guide. To report a problem without authoring a rule, see support.
