AL code review

Reviews AL source changes by composing the leaf AL review skills. This is the canonical reference implementation of a super-skill — skill authors writing composed reviews should copy its structure.

al-code-review does not evaluate knowledge files directly. It invokes each of its sub-skills against the same task input, collects their findings-reports, and then performs its own self-review pass over the diff using the agent's built-in BC and AL knowledge. BCQuality knowledge is an additive layer: anything the sub-skills found is cited from BCQuality, and anything the agent finds on its own is validated against BCQuality (cited if matched, suppressed if contradicted, surfaced as an agent finding otherwise). The result is a single rolled-up findings-report that mixes knowledge-backed and agent findings, each clearly tagged via from-sub-skill.

An orchestrator invokes this skill with either a pr-diff (the standard PR-review entry point) or a file-path (single-file review). The skill produces a single JSON document conforming to the DO output contract, extended with sub-results and — when applicable — skipped-sub-skills.

Source

The sub-skills invoked by this skill are those listed in frontmatter sub-skills:

• microsoft/skills/review/al-performance-review.md
• microsoft/skills/review/al-security-review.md
• microsoft/skills/review/al-privacy-review.md
• microsoft/skills/review/al-upgrade-review.md
• microsoft/skills/review/al-style-review.md
• microsoft/skills/review/al-ui-review.md

Additional leaf skills (for example, telemetry, testing) are added by updating the sub-skills list. The skill does not discover sub-skills implicitly.

Relevance

A sub-skill is relevant when both of the following hold:

• The orchestrator has supplied inputs that satisfy the sub-skill's declared inputs.
• The orchestrator has not disabled the sub-skill via configuration.

Per the DO contract, the super-skill MUST NOT filter sub-skills by task content. al-code-review does not inspect the PR diff to predict whether, for example, there is anything for al-security-review to find. Each leaf is responsible for its own task-level applicability decision; leaves signal non-applicability by returning outcome: "not-applicable" or outcome: "no-knowledge".

Sub-skills that fail either check are not invoked and are recorded in skipped-sub-skills:

• reason: "configuration" when the orchestrator disabled the sub-skill.
• reason: "not-applicable" when the orchestrator's inputs do not satisfy the sub-skill's declared inputs.

Worklist

The worklist is the list of sub-skills judged relevant by the previous step. Every sub-skill in the worklist will be invoked in the Action step.

Action

Roll up sub-skill findings

For each sub-skill in the worklist:

1. Invoke the sub-skill with the orchestrator's inputs, passing only the subset each sub-skill declares in its inputs.
2. Capture the sub-skill's complete findings-report verbatim and append it to sub-results.
3. If the sub-skill's outcome is failed, stop here for this sub-skill: its findings are not reliable per the DO contract and MUST NOT be copied into the super-skill's top-level findings[] or counted in summary.counts.
4. Otherwise, append each entry from the sub-skill's findings[] to the super-skill's top-level findings[], setting from-sub-skill to the sub-skill's skill.id. For non-citation findings (those whose id is a skill-defined slug rather than a reference path), prefix id with <from-sub-skill>: to prevent collisions across sub-skills. Other finding fields are preserved.

Agent self-review pass

After the sub-skill rollup, perform a self-review pass against the same task input using the agent's built-in BC and AL knowledge. BCQuality is an additive knowledge layer: it augments the agent's review judgement, it does not replace it. The goal of this pass is to surface defects the agent recognises on its own — bugs, anti-patterns, error-handling gaps, AL idioms — that the leaf sub-skills did not catch because no BCQuality knowledge file covers them yet.

For every candidate the agent identifies in this pass:

1. Validate against BCQuality knowledge. Check the candidate against the knowledge files the sub-skills have already loaded for this task (visible via their references and suppressed lists in sub-results).
   • If a BCQuality knowledge file matches the candidate, upgrade it to a knowledge-backed finding: cite the file in references, set id to the file's path, set from-sub-skill to the sub-skill that owns that knowledge domain, and merge with or deduplicate against any sub-skill finding that already covers the same concern at the same location.
   • If a BCQuality knowledge file explicitly contradicts the candidate (its ## Best Practice or ## Anti Pattern says the opposite of what the agent flagged), suppress the candidate and do not surface it.
   • Otherwise the candidate has no BCQuality coverage; emit it as an agent finding.
2. Emit agent finding. Per DO's Agent findings rules:
   • from-sub-skill: "agent"
   • references: []
   • id is a skill-defined slug prefixed with agent: (for example, agent:missing-error-handling-on-http-call).
   • confidence capped at medium.
   • message is non-empty and self-contained, describing both the issue and a concrete recommendation. A consumer rendering the finding has no knowledge-file footer to fall back on.

Leaf sub-skills MUST NOT emit agent findings: their scope is bounded by the knowledge subset they evaluate. The self-review pass is a super-skill responsibility.

Summary and rollup

Aggregate summary.counts and summary.coverage as the sums across invoked sub-skills whose outcome is not failed. Agent findings emitted by the super-skill itself contribute to summary.counts but not to summary.coverage (coverage is a sub-skill worklist metric and is undefined for self-review).

suppressed[] at the super-skill level remains empty. Knowledge-file-level suppression is reported by each sub-skill within its own entry in sub-results.

Derive outcome using the DO rollup rules. outcome-reason is populated for partial and failed and SHOULD summarize per-sub-skill state, for example: "al-security-review failed (tool timeout); al-performance-review completed."

Output conforms to the DO output contract, extended with sub-results and skipped-sub-skills. A populated example — both leaves ran, each produced findings:
