doc-naming
Purpose
The naming authority for the 8-layer SDD flow. doc-naming validates document
IDs, element IDs, threshold tags, and file names against
${CLAUDE_PLUGIN_ROOT}/framework/governance/ID_NAMING_STANDARDS.md, and flags removed/legacy
patterns. It produces no artifacts — it is the declarative ID validator (the
framework ships no runtime code).
Layer: cross-cutting utility (applies to all 8 layers).
When to Use
Use before creating or editing any artifact, to:
- verify a document or element ID format,
- check a
@threshold: tag, or
- detect removed/legacy ID patterns and get the migration target.
Do NOT use for cross-document traceability or content review — use
../doc-validator/SKILL.md.
Behavior
1. Document ID — TYPE-NN
^[A-Z]{2,8}-[0-9]{2,}$ — uppercase type, single dash, 2+ digit sequence (no
extra leading zeros beyond two: BRD-01, ADR-99, IPLAN-102). File name:
TYPE-NN_descriptive_slug.md.
2. Element ID — TYPE.NN.SS.xxxx (4-segment)
^[A-Z]+\.[0-9]{2,}\.[0-9]{2,}\.[a-f0-9]{4,8}$
| Segment | Meaning | Format |
|---|
| TYPE | Artifact prefix | BRD PRD EARS BDD ADR TDD |
| NN | Document number | 2+ digits |
| SS | Source section number | 2+ digits |
| xxxx | Stable content identifier, 4 hex (8 on collision) — see below | [a-f0-9]{4,8} |
Example: BRD.01.07.a7f3. Element IDs appear as markdown headings
(### BRD.01.07.a7f3: Title).
3. Reference granularity (element vs document)
There are no numeric element-type codes — identity is the section + hash,
not a fixed code.
| Layer | Reference form | Example |
|---|
| BRD, PRD, EARS, BDD, TDD | element (dotted) TYPE.NN.SS.xxxx | PRD.01.09.1dbc |
| ADR | both: document ADR-NN and element ADR.NN.SS.xxxx | ADR-05, ADR.05.03.e5b1 |
| SPEC, IPLAN | document (dash) TYPE-NN | SPEC-06, IPLAN-01 |
Traceability tags carry these refs: @brd: BRD.01.07.a7f3, @spec: SPEC-06,
@iplan: IPLAN-01.
4. Threshold tags
@threshold: {TYPE}.{NN}.{key} where key is
category.subcategory.attribute[.qualifier]. Categories: perf timeout rate retry circuit alert cache pool queue batch. Doc reference is mandatory and
dot-separated — @threshold: PRD.035.timeout.partner.bridge (valid);
@threshold: timeout.partner.bridge (missing doc ref — invalid). Threshold
sources: BRD (business SLAs), PRD (product metrics), ADR (technical limits).
5. Reserved-ID and REF exemptions
TYPE-00_* (indexes, templates, glossaries) — framework infrastructure;
skip element-ID and traceability checks.TYPE-REF-NN_{slug}.md (BRD/ADR only, via ../doc-ref/SKILL.md) —
free-format reference targets; no element IDs, no quality gates.
6. Removed / legacy patterns (reject)
Migrate every match to TYPE.NN.SS.xxxx (or a dash doc ref for SPEC/IPLAN):
| Removed | Applies to |
|---|
AC-XXX, FR-XXX, BC-XXX, BA-XXX, QA-XXX, BO-XXX, RISK-XXX, METRIC-XXX, Feature F-XXX | BRD, PRD |
Event-XXX, State-XXX | EARS |
DEC-XXX, ALT-XXX, CON-XXX | ADR |
3-segment TYPE.NN.xxxx | all element layers |
Detect with grep, e.g. grep -E "(AC|FR|BC|BA|QA|BO|NFR|RISK|METRIC)(-[A-Za-z0-9]+)*-[0-9]+" file.md
(the optional (-[A-Za-z0-9]+)* catches compound forms like FR-CICD-001).
Migration: derive TYPE/NN from the file name, SS from the source section,
and xxxx as a stable 4-hex identifier distinct within its section; replace
all occurrences and re-verify. Do not compute SHA-256 by hand. For BRD §7 —
the one layer with a defined field-extraction boundary — call the generator:
python -m sdd_doc_lint.rehash --compute --doc-id NN --section-id SS --title T --description D. Authority: framework/governance/ID_NAMING_STANDARDS.md.
7. ISO 8601 timestamps
Date/time fields (frontmatter last_updated, created_date; review_date,
fix_date, approval_date, decision_date) use
YYYY-MM-DDTHH:MM:SS (optionally Z or ±HH:MM), enabling same-day drift
detection. Date-only values are deprecated.
