Purpose
Route the Specification-Driven Development (SDD) workflow: point at the
right skill for the task, report current position, enforce the
upstream-artifact policy. doc-flow never creates artifacts itself — the
artifact skills do.
Layer: cross-cutting (no upstream; routes into all 8 layers).
Authoritative spec: ${CLAUDE_PLUGIN_ROOT}/framework/SPEC_DRIVEN_DEVELOPMENT_GUIDE.md.
When to Use
| Situation | Action |
|---|---|
| Unsure which skill applies | Use doc-flow (this) |
| Brand-new project | ../project-init/SKILL.md first, then doc-flow |
| Adopting SDD into existing code | ../project-adopt/SKILL.md first |
| Editing a published artifact | ../doc-chg/SKILL.md — not the linear flow |
| Single-layer end-to-end generation | that layer's -autopilot |
The 8-layer flow
BRD (1) → PRD (2) → EARS (3) → BDD (4) → ADR (5) → SPEC (6) → TDD (7) → IPLAN (8) → Code
| Layer | Artifact | Purpose | Base skill |
|---|---|---|---|
| 1 | BRD | Business requirements | doc-brd |
| 2 | PRD | Product requirements & KPIs | doc-prd |
| 3 | EARS | Formal WHEN-THE-SHALL requirements | doc-ears |
| 4 | BDD | Gherkin test scenarios | doc-bdd |
| 5 | ADR | Architecture decisions | doc-adr |
| 6 | SPEC | Technical specifications | doc-spec |
| 7 | TDD | Test-case definitions & thresholds | doc-tdd |
| 8 | IPLAN | Executable implementation plan | doc-iplan |
Each layer ships four skills: base (create), -autopilot (end-to-end),
-audit (gate report), -fixer (apply audit fixes).
Skill selection
| You have | You need | Use |
|---|---|---|
| Nothing | Business requirements | doc-brd |
| BRD | Product requirements | doc-prd |
| PRD | Formal requirements | doc-ears |
| EARS | Test scenarios | doc-bdd |
| BDD | Architecture decisions | doc-adr |
| ADR | Technical specifications | doc-spec |
| SPEC | Test-case definitions | doc-tdd |
| TDD | Implementation plan | doc-iplan |
| IPLAN | Code | Implement |
| Any stage | Supplementary docs | doc-ref |
Intent → skill (when the layer is clear, pick by verb):
| Action | Skill |
|---|---|
| create / draft | layer's base or -autopilot |
| audit / score | layer's -audit |
| fix / remediate | layer's -fixer |
| validate / trace / links / orphans | ../doc-validator/SKILL.md |
| change a published artifact | ../doc-chg/SKILL.md + ../gate-check/SKILL.md |
| roadmap / phasing | ../adr-roadmap/SKILL.md |
| scaffold / new project | ../project-init/SKILL.md |
| adopt / brownfield | ../project-adopt/SKILL.md |
| tailor / profile | ../project-profile/SKILL.md |
| security / threats | ../security-audit/SKILL.md |
When the user names a skill, run it directly.
Where you are & what's next
Where you are. Scan docs/<NN>_<X>/ for artifacts; read each Document
Control Status (most layers Draft → In Review → Approved; IPLAN
Draft → In Progress → Completed). Map to the project's active layers
(see Adaptation); report position + progress = terminal-status artifacts ÷
active layers.
Template-conformance check (mandatory). For every artifact found, load
${CLAUDE_PLUGIN_ROOT}/framework/layers/<NN>_<X>/<TYPE>-TEMPLATE.yaml and
verify every required top-level section appears as a ## heading. Report
missing sections as drift findings (Status notwithstanding), e.g.
"BRD-01 missing 6 of 18 required sections: …". Do not rationalise
drift as a "compact" variant, "documented walkthrough", or "lint-pinned"
exception — one template, one canonical section list. Lint passing is the
structural subset, not full template conformance. Recommend
doc-<layer>-fixer (or -autopilot for a re-author) to close gaps.
What's next. Recommend the next artifact per the cumulative chain (each layer needs its prerequisite). Prioritise:
- P0 — required upstream missing OR next step on the critical-path spine.
- P1 — next ready layer once P0 is unblocked.
- P2 — optional / parallel work (extra ADRs,
doc-refsupplements).
Surface parallel-work opportunities (independent tracks with no shared prerequisite); name the skill to run for each.
Context scan (before authoring). Rank candidate upstream documents for
the target type by directness, topic match, recency, and Approved status;
collect project vocabulary (titles, headings, glossary) so the new document
reuses real IDs and consistent terms.
Utility skills
| Skill | Use for |

Implementation roadmaps from ADRs |
../security-audit/SKILL.md |
Security review (OWASP/CWE, STRIDE) |
Change management
Changes to already-published artifacts use the CHG overlay, not the
linear flow. ../doc-chg/SKILL.md (+ -autopilot / -audit / -fixer)
classifies the change (C1–C3 / Emergency) and routes it to the right gate;
../gate-check/SKILL.md runs the gate (GATE-01/03/06/08/CODE, or
GATE-SPEC for framework/ spec changes) and prepares the sign-off
form. A human approves — the skill never does.
Upstream-artifact policy
Do NOT invent missing upstream artifacts. Every artifact must trace to a real business/product justification.
| Situation | Action |
|---|---|
| Upstream exists | Reference with its exact ID |
| Required upstream missing | Skip; report; advise creating it first |
| Optional upstream missing | null in the tag |
| Not applicable | Omit the tag |
Validation model
Each skill is the validator (no runtime code). After each artifact,
run that layer's -audit; before moving on, confirm cumulative upstream
tags are present (PRD→1 … IPLAN→7).
Adaptation
Read .aidoc/profile.yaml. Honor active_layers: a disabled skippable
layer (BDD / ADR) is excluded from the critical path, the progress
denominator, and next-step recommendations. Ignore unknown keys; absent
a profile, use the full 8-layer flow.
Authority: ${CLAUDE_PLUGIN_ROOT}/framework/governance/ADAPTATION.md.
Reading bundled files
Skill paths use ${CLAUDE_PLUGIN_ROOT}/framework/…. CLAUDE_PLUGIN_ROOT
is an env var Claude Code sets at install — never a literal folder
name. In a shell it expands (cat "$CLAUDE_PLUGIN_ROOT/framework/…"); if
unset, the framework/ bundle ships beside skills/ at the plugin root.
Never open the literal ${CLAUDE_PLUGIN_ROOT} text.
