The knowledge corpus now covers performance, security, privacy, upgrade,
style, and UI. Previously only two leaf reviewer skills existed
(al-performance-review, al-security-review), so four of the six domains
had knowledge with no skill sourcing from them. A community reader
landing in privacy/, upgrade/, style/, or ui/ would see articles with
no apparent consumer.
Three changes:
1. Move existing review skills into `microsoft/skills/review/`. The
`review/` subfolder groups all review-kind skills together and leaves
room for future non-review action skills at the `microsoft/skills/`
level. Updates references in README.md, agent-consumption.md, and
skills/entry.md to the new paths.
2. Add four new leaf reviewer skills — al-privacy-review,
al-upgrade-review, al-style-review, al-ui-review — each following
the same DO template as al-performance-review/al-security-review but
sourcing from the corresponding knowledge domain. al-upgrade-review
and al-ui-review return `not-applicable` when the diff contains no
upgrade surface or no page files, respectively.
3. Update al-code-review to compose all six leaf skills and retarget
the dangling references in every populated JSON example
(`use-setloadfields.md`, `no-plaintext-secrets-in-telemetry.md`,
`avoid-implicit-commit.md` — none of which exist in the corpus) to
real knowledge files: `call-setloadfields-before-filters.md`,
`use-secrettext-for-credentials.md`, `never-hardcode-secrets-in-al.md`.
Validator passes with 0 errors / 0 warnings.
Most of the corpus — FindSet/SetLoadFields/CalcFields patterns, permission
sets, SingleInstance codeunits, DataClassification, IsolatedStorage,
transaction scope, SecretText — describes BC platform behaviour that is
identical across supported versions. The seed [26..28] range on every
file implied a version-specificity the content does not actually have,
and there was no way to express "applies to every version" in the
schema the way [w1] and [all] already do for countries and
application-area.
Extend the v1 schema with a universal sentinel for bc-version, parallel
to the sentinels already defined for the other dimensions:
bc-version: [all] # applies to every BC version
[all] is mutually exclusive with explicit versions. Range shorthand
([26..28]) and explicit lists ([26, 27, 28]) continue to work for files
genuinely tied to a version-gated API or deprecation.
Update read.md (field definition, matching semantics, partial-context
rule), write.md (default to [all], use ranges only with a concrete
reason), README.md (frontmatter example), and the CI validator. All
forty existing knowledge files and the three action skills convert to
[all]; none of the current content is version-gated. Validator passes.
Remove seven knowledge files whose content is generic software-engineering
guidance that a capable LLM already applies without BCQuality present
(HTTPS-only, secret-leakage-in-errors, no-credentials-in-URLs, silent
security-error swallowing, short transaction scope, HTTP timeouts,
StrSubstNo-vs-concatenation). These fail the remedial-knowledge premise
and dilute the signal of the preview corpus.
Strip the "Seed article — domain stewards should expand" banner from ten
files that are ready to showcase (AA0232/AA0233 rules, FindSet read-only
semantics, SetLoadFields ordering and usage, CalcFields-in-loops,
SecretText end-to-end, DataClassification). The banner remains on files
that still need domain-steward refinement.
Add a "What belongs here" section to the README stating the admission
test: a file exists only if a modern LLM would get something wrong or
miss something without it. Gives contributors a concrete yes/no filter
before they open a PR.
- Introduced unit tests for the bc-domain-context implementation, covering various scenarios including filtering by application area, technology mismatches, layer precedence, and conditional applicability.
- Added knowledge files related to finance, including topics such as Chart of Accounts, Codeunit 12, Dimension Management, and VAT on prepayment chains, among others.
- Each knowledge file includes structured metadata and best practices to enhance the domain knowledge available for Business Central tasks.
Add a new skill kind, 'entry-point', and its sole instance at
skills/entry.md. When an orchestrator points an agent at BCQuality,
the agent's first call is Entry: it receives a task context and
returns a dispatch record naming the action skill(s) to invoke.
Routing logic lives in Entry, not in the orchestrator.
Entry structurally follows DO's Source -> Relevance -> Worklist ->
Action pattern but the units it selects are action skills (not
knowledge files) and its output is a dispatch record (not a
findings-report).
Contract highlights:
- Inputs semantics in DO clarified as any-of: orchestrator supplies
whichever listed input types it has; skill must return
'not-applicable' if the subset is insufficient. This matches
the existing al-* canonical skills which declare
[pr-diff, file-path] as alternatives.
- Relevance admits candidates whose inputs intersect
inputs-available, not whose inputs are a subset.
- Dispatched inputs are the intersection, not the full
inputs-available set, to avoid leakage between skills.
- Super-skill precedence in Worklist supersedes a sub-skill only
when the goal is a broader match for the super than the sub.
When the goal specifically names a concern the sub handles
(e.g., 'performance review'), the sub wins and the super is
dropped with reason 'narrower-sub-skill-selected'.
- Skill layer precedence is defined here as custom > community >
microsoft, matching READ's rule for knowledge files.
- skipped[] carries 'superseded-by' for layer-precedence,
sub-skill, and super-skill drops, for traceability.
Propagate the concept through:
- skills/README.md: distinguish the runtime entry-point skill from
the three meta-skill contracts.
- skills/do.md: acknowledge entry-point alongside meta-skills as
the only kinds that live outside a layer.
- README.md: rewrite the Skills and Agent bootstrapping sections
so the bootstrap instruction is 'invoke /skills/entry.md first'.
- agent-consumption.md: update the Mermaid flow and step narrative
to show Entry dispatch, with READ and DO read on demand.

The /samples/ top-level tree is replaced with sibling files in each
knowledge-layer folder. An article and its demonstrations now live
side-by-side:
microsoft/knowledge/<domain>/<slug>.md
microsoft/knowledge/<domain>/<slug>.good.al
microsoft/knowledge/<domain>/<slug>.bad.al
Rationale:
- Proximity. An article and its paired samples are one unit; the
filesystem now reflects that.
- Layer ownership. Samples inherit layer precedence for free -- a
/custom/ fork can override an article and its samples atomically,
which the shared /samples/ tree previously made awkward.
- Trivial migration path. Action-skill source globs
(*/knowledge/<domain>/**/*.md) are unchanged; sample discovery is a
sibling-filename lookup.
Changes:
- git mv of all 65 sample files from samples/<domain>/<slug>/{bad,good}.al
to microsoft/knowledge/<domain>/<slug>.{bad,good}.al (history preserved).
- Update See-sample references in all 37 articles that ship samples.
- skills/read.md: replace the no-code-blocks bullet with a pointer to a
new Sample files section that fully specifies the sibling convention,
the kinds (good/bad + forward-compatible), multi-technology rules,
demonstration-only status, and layer-precedence behaviour.
- skills/write.md: update the samples pointer to match.
- README.md: annotate the knowledge tree with the sample sibling shape.
- samples/README.md deleted; content lifted into skills/read.md.
- Both generators (C:\temp\gen_performance_knowledge.py,
C:\temp\gen_security_knowledge.py) updated to emit at the new paths
and to stop writing samples/README.md. Re-running them is idempotent
against the committed layout.

DO contract (skills/do.md)
- New 'sub-skills' optional frontmatter field on action skills: when
present and non-empty, the skill is a super-skill that composes
other action skills.
- New 'Composition (super-skills)' section covering section
interpretation, outcome rollup, summary aggregation, and suppression
scope.
- Output schema gains three optional fields: 'from-sub-skill' on each
finding, top-level 'sub-results[]' carrying nested findings-reports,
and top-level 'skipped-sub-skills[]'.
- Super-skills MUST NOT filter sub-skills by task content; leaves own
task-level applicability and signal via outcome.
- Findings from a failed sub-skill MUST NOT flow into the parent's
findings[] or counts, consistent with DO's rule that consumers
ignore a failed skill's findings. Reports are still preserved in
sub-results[] for traceability.
- Rolled-up non-citation finding ids MUST be prefixed with the sub-
skill id to prevent collisions across sub-skills. Citation-based
ids are already unique via repo path and are not rewritten.
- Outcome rollup rules updated: 'partial' covers S = {partial},
{partial, partial}, and {partial, failed}. Empty worklist rolls up
to 'not-applicable' with outcome-reason.
- Nested super-skills are not permitted in v1.
Reference skills (microsoft/skills/)
- al-code-review.md rewritten as the canonical super-skill: lists
al-performance-review and al-security-review as sub-skills, orch-
estrates invocation, aggregates output, and includes a worked
rolled-up JSON example plus the empty-corpus rollup.
- al-performance-review.md added as a leaf reference skill for the
performance knowledge domain.
- al-security-review.md added as a leaf reference skill for the
security knowledge domain.
- Both leaves retain the leaf-level rules validated in the prior
pass: partial-context message requirement, worklist-scoped
suppression, application-area semantics, and the platform-guarantee
threshold for blocker severity.
README updated to describe leaf vs super-skill and link all three
reference skills.
Two rubber-duck passes tightened the contract and caught schema
violations in the worked examples before commit.

- microsoft/skills/al-code-review.md: full action skill reviewing AL
source changes. Exercises every part of the DO contract:
- frontmatter with all required action-skill fields and the four
optional knowledge filters
- all five required sections (Source, Relevance, Worklist, Action,
Output) in order
- applicability-based filtering with READ's partial-context rule,
including the requirement to name unknown dimensions in the
finding message
- conflict resolution and suppression scoped to worklist candidates
- full outcome taxonomy handled (completed, no-knowledge,
not-applicable, partial, failed), including the current empty-
corpus state
- worked JSON output example showing structured references,
per-finding confidence, and a suppression entry
- README.md: link the skill as the canonical reference so skill
authors have a starting point.
Two rubber-duck passes caught and fixed contract precision issues
before commit: location.line/range consistency, partial-context
message requirement, over-broad suppression scope, application-area
matching semantics, and the blocker severity threshold.

- skills/read.md (READ, Schema + Use) — knowledge-file contract:
frontmatter schema, required/optional sections (normative vs
non-normative), layer precedence with applicability-based conflict
detection, explicit frontmatter matching semantics (including
partial-context handling).
- skills/do.md (DO, Action Skill) — action-skill template:
frontmatter schema, required sections, four-step pattern
(Source -> Relevance -> Worklist -> Action), and the output contract
as a JSON schema with outcome, findings, structured references,
confidence, and mandatory suppression recording. Includes a worked
example.
- skills/write.md (WRITE, New Knowledge) — authoring guide:
atomicity, size, section guidance, field-by-field choices, file
naming, layer choice, pre-PR checklist. Defers to READ for the
format spec.
- README.md — link the three files from the meta-skills section and
update the output-contract paragraph to include outcome and
suppressed.
- agent-consumption.md — update step 5 (Agent emits structured output)
to match the richer DO contract.
