Nw Roadmap

NW-ROADMAP: Goal Planning

Wave: CROSS_WAVE Agent: Architect (nw-solution-architect) or domain-appropriate agent

Overview

Dispatches expert agent to fill a pre-scaffolded YAML roadmap skeleton. CLI tools handle structure; agent handles content.

Output: docs/feature/{feature-id}/deliver/roadmap.json

Usage

/nw-roadmap @nw-solution-architect "Migrate monolith to microservices"
/nw-roadmap @nw-software-crafter "Replace legacy authentication system"
/nw-roadmap @nw-product-owner "Implement multi-tenant support"

Execution Steps

You MUST execute these steps in order. Do NOT skip any.

1. Parse Parameters — Extract agent name (after @, validated against agent registry), goal description (quoted string), and derive feature-id from goal in kebab-case (e.g., "Migrate to OAuth2" -> "migrate-to-oauth2"). Gate: agent name, goal, and feature-id all resolved.

2. Scaffold Skeleton — Run des.cli.roadmap init via Bash BEFORE invoking agent. Gate: CLI exits 0; stop and report error on non-zero exit.

des-roadmap init \
  --project-id {feature-id} \
  --goal "{goal-description}" \
  --output docs/feature/{feature-id}/deliver/roadmap.json

For complex projects add: --phases 3 --steps "01:3,02:2,03:1"

Do NOT write the file manually.

3. Invoke Agent — Invoke the named agent via Task tool to fill skeleton TODO placeholders. Gate: agent completes without error.

@{agent-name}

Fill in the roadmap skeleton at docs/feature/{feature-id}/deliver/roadmap.json.
Replace every TODO with real content. Do NOT change the YAML structure
(phases, steps, keys). Fill in: names, descriptions, acceptance criteria,
time estimates, dependencies, and implementation_scope paths.

Goal: {goal-description}

# Test paradigm mandate (STANDING 2026-05-05) — apply per test level

GUARD — emit by deliverable_type (ADR-PST-003 / OPEN-5-A): the mandate
block below applies ONLY when `deliverable_type == application` (or when
deliverable_type is unset — application is the default). For a plugin/skill
deliverable, do NOT emit the mandate; instead include this one-line directive
in each step's `implementation_notes`:

  STRUCTURAL VERIFICATION (mandatory, plugin/skill): This step ships prompt
  text / config / docs, not application code, so the Hypothesis + state-delta
  unit mandate does not apply. Verify the deliverable structurally — a golden
  assertion (skill-lint) over the changed markdown/config asserting the
  required block is present and correctly shaped — gated at CI + pre-push.

When `deliverable_type == application` (or unset), for EVERY step's
`implementation_notes`, include this directive verbatim unless the step is
documented as exempt:

  TEST PARADIGM (mandatory): Unit tests for this step MUST be written as
  property-based tests using Hypothesis @given strategies + state-delta
  matchers (assert_state_delta over a declared universe with strict=True).
  Single-example unit tests are FALLBACK only — document why in a
  `# bypass:` comment if used. Acceptance scenarios MUST be framed as
  Property: blocks (quantified preconditions + invariant outcomes) where
  the contract supports it; classic Scenario: is fallback. Integration
  and E2E tests REMAIN single-example — they verify wiring, not
  invariants. Universe declaration is mandatory even when only one slot
  is checked: the unchanged() predicate covers the rest.

  STAGE CONTEXT (cascade): NEW code = Stage 0 (paradigm-from-day-zero,
  no debt accumulates). Bug-prone legacy code = Stage 1 first (state-
  delta migration captures hidden mutations, 33-75% yield), THEN Stage 2
  PBT amplification (low yield by design — surface is debt-paid). Don't
  expect high hit rate on Stage-1-completed surfaces; that's healthy.
  See nw-tdd-methodology::Paradigm Mandate for the full debt-payoff
  framing.

When a step's contract genuinely cannot be expressed as a property
(e.g., golden-file diff, exact error string, single-shot UI flow),
include in `implementation_notes`:

  EXEMPT FROM PARADIGM: <one-sentence reason>. Compensate with
  property-based test at <unit|integration> level on adjacent slot.

Context to pass (if available): measurement baseline|mikado-graph.md|existing docs.

4. Validate — Run des-roadmap validate via Bash. Gate: exit 0 = success; exit 1 = print errors and stop; exit 2 = usage error, stop.

des-roadmap validate docs/feature/{feature-id}/deliver/roadmap.json

Invocation Principles

Keep agent prompt minimal. Agent knows roadmap structure and planning methodology.

Pass: skeleton file path + goal description + measurement context (if available). Do not pass: YAML templates|phase guidance|step decomposition rules.

For performance roadmaps, include measurement context inline so agent can validate targets against baselines.

Success Criteria

Dispatcher (you) — all 4 must be checked

• 1. Parameters parsed (agent name, goal, feature-id)
• 2. des.cli.roadmap init executed via Bash (exit 0)
• 3. Agent invoked via Task tool to fill TODO placeholders
• 4. des.cli.roadmap validate executed via Bash (exit 0)

Agent output (reference)

• 5. All TODO placeholders replaced with real content
• 6. Steps are self-contained and atomic
• 7. Acceptance criteria are behavioral and measurable
• 8. Step decomposition ratio <= 2.5 (steps / production files)
• 9. Dependencies mapped, time estimates provided

Error Handling

• Invalid agent: report valid agents and stop
• Missing goal: show usage syntax and stop
• Scaffold failure (exit 2): report CLI error and stop
• Validation failure (exit 1): print errors, do not proceed

Examples

Example 1: Standard architecture roadmap

/nw-roadmap @nw-solution-architect "Migrate authentication to OAuth2"

Derives feature-id="migrate-auth-to-oauth2", scaffolds skeleton, invokes agent to fill TODOs, validates. Produces docs/feature/migrate-auth-to-oauth2/deliver/roadmap.json.

Example 2: Performance roadmap with measurement context

/nw-roadmap @nw-solution-architect "Optimize test suite execution"

Passes measurement data inline. Agent fills skeleton, validates targets against baseline, prioritizes largest bottleneck first.

Example 3: Mikado refactoring

/nw-roadmap @nw-software-crafter "Extract payment module from monolith"

Agent fills skeleton with methodology: mikado, references mikado-graph.md, maps leaf nodes to steps.

Workflow Context

/nw-roadmap @agent "goal"           # 1. Plan (init -> agent fills -> validate)
/nw-execute @agent "feature-id" "01-01" # 2. Execute steps
/nw-finalize @agent "feature-id"        # 3. Finalize
