# BCQuality AL review

This skill drives the BCQuality **Entry protocol** over the knowledge base that ships
inside this plugin. It is the plugin entry point for consumers (orchestrators, CLIs)
that do not already know BCQuality's internal conventions — the only convention they
need is "invoke this skill for an AL review."

BCQuality itself is orchestrator-agnostic content: knowledge files plus routing and
action skills. This bridge is the thin consumer glue that lets a plugin host run that
content without hardcoding BCQuality's layout.

## When to use

- Reviewing an AL pull request or an uncommitted working-tree diff.
- Reviewing a single AL file.
- Any task whose goal is "review Business Central / AL code for quality issues."

Do **not** use this skill to *generate* AL code — it only reviews.

## Plugin root

Resolve `PLUGIN_ROOT` to the directory that contains this plugin's root
`plugin.json`. This skill lives at
`PLUGIN_ROOT/skills/bcquality-al-review/SKILL.md`, so `PLUGIN_ROOT` is two levels up
from this file. All paths below are relative to `PLUGIN_ROOT`. If the host exposes a
plugin-root environment variable, prefer it.

## Steps

1. **Refresh the knowledge index (best effort).** If `pwsh` is available, run
   `pwsh PLUGIN_ROOT/tools/Build-KnowledgeIndex.ps1` from `PLUGIN_ROOT` to (re)generate
   `PLUGIN_ROOT/knowledge-index.json` over the installed tree. This is a discovery
   accelerator only — if `pwsh` is missing or the build fails, continue; the review
   skills fall back to path-based discovery.

2. **Run Entry.** Read `PLUGIN_ROOT/skills/entry.md` and execute it against a
   task context describing the review:

   ```yaml
   task-context:
     goal: "Review the AL changes for quality issues"
     inputs-available: [pr-diff]        # or [file-path] for single-file review
     technologies: [al]
     enabled-layers: [microsoft, community, custom]   # see "Layer selection" below
   ```

   **Layer selection.** `enabled-layers` defaults to all three layers. A host can
   narrow it by setting the `BCQUALITY_ENABLED_LAYERS` environment variable to a
   comma-separated subset (e.g. `microsoft` or `microsoft,community`); when set, pass
   exactly those layers instead of the default. This is the plugin path's only knob
   for layer policy — see the limitation in Notes.

   Fill `bc-version`, `countries`, and `application-area` only when the caller
   supplies them; omit them otherwise (an omitted dimension is unconstrained).

3. **Follow the dispatch record.** Entry returns a dispatch record naming the action
   skill(s) to invoke — for a PR review this is normally
   `microsoft/skills/review/al-code-review.md`. For each dispatched skill, read the
   file and execute its Source → Relevance → Worklist → Action steps, reading
   `PLUGIN_ROOT/skills/read.md` and `PLUGIN_ROOT/skills/do.md` on demand.
   When `al-code-review` composes its leaves and the host supports child contexts or
   separate model calls, run each leaf in an isolated context and roll up the returned
   JSON. Pass each call the exact index rows for that leaf's domain so references can
   be copied verbatim. This is the preferred execution profile for fast/small models;
   do not force one generation to retain all domain knowledge at once.

4. **Emit findings.** Produce the rolled-up findings report in the DO output contract,
   including each review finding's producer-supplied `domain` label (`outcome`,
   `findings`, `references`, `confidence`, `suppressed`). Do not invent a different
   shape; downstream consumers parse the DO contract without skill-specific logic.
   Apply DO's reference-integrity gate before returning: every knowledge-backed path
   must exist in the installed tree, must have been opened in full, and must be copied
   verbatim. Never synthesize a plausible article slug.

If Entry returns `no-match` or `failed`, return the dispatch record unchanged so the
caller can log the reason.

## Notes

- This skill adds nothing to BCQuality's knowledge or routing logic; it only bootstraps
  the existing Entry protocol from a plugin host. Knowledge and skill changes belong in
  the layers under `PLUGIN_ROOT/microsoft/`, `PLUGIN_ROOT/community/`, and
  `PLUGIN_ROOT/custom/`, not here.
- **Layer pruning is coarser than the URL/clone model.** In the clone model a consumer
  prunes its checkout to policy *before* the agent runs, and the knowledge index is
  rebuilt over the pruned tree, so a denied layer can never leak into discovery. A
  plugin install ships the whole tree, so this bridge can only *narrow discovery* via
  `enabled-layers` (`BCQUALITY_ENABLED_LAYERS`) — the denied layers' files still exist on
  disk. Treat `enabled-layers` as a selection filter, not a hard security boundary. A
  future revision could add a genuine deny mechanism (e.g. pruning the installed tree).
- **Manifest location.** This plugin's manifest is the root `plugin.json`, which both
  Claude Code and Copilot CLI accept (verified with Copilot CLI: `plugin install`
  reports the bridge skill loaded). A `.claude-plugin/marketplace.json` alongside it
  carries the marketplace entry. Claude Code also reads `.claude-plugin/plugin.json`; if
  a future host only reads that form, dual-home the manifest there.
