name: cy-create-spec description: Creates the unified Spec (_spec.md with Product and Technical parts) plus its companion catalogs — _user_stories.md, the _dx.md developer-experience contract, the _uiux.md UI change map for UI-bearing features, and the _tests.md test contract — through a two-stage frontier grill with parallel codebase and market research. Use when starting a new feature or product, specifying requirements or technical design, or updating an existing spec and its companions. Do not use for task breakdown, review remediation, or direct code implementation.

Create Spec

Author one _spec.md carrying the full arc from product intent to implementation design, plus the companion catalogs. Every artifact is written for the LLM agents that consume it downstream (cy-create-tasks, cy-execute-task, review rounds): supply business rules, domain behavior, product intent, and implementation design. KPIs, success metrics, timelines, and rollout phases have no consumer in this pipeline — leave them out. All artifacts in English, active voice; every sentence earns its place.

The spec has two parts written in two stages, separated by a checkpoint:

• Part I — Product: WHAT users need, WHY it provides value, WHO the users are. Closes with _user_stories.md.
• Part II — Technical: first the public surface (_dx.md, and _uiux.md when UI-bearing), then HOW to implement it. Closes with _tests.md.

<HARD-GATE> - Research before questions: every stage's grill MUST be fed by research first — codebase and market for Stage 1, architecture exploration for Stage 2. - Grill before writing: the user MUST shape each part by answering grill rounds — for every spec, however simple. "Simple" features are where unexamined assumptions cause the most rework; a short grill is fine, a skipped grill is not. - Checkpoint between stages: Stage 2 opens only after the user confirms the Stage 1 summary. - Surface before internals: the grilled `_dx.md`/`_uiux.md` freeze before internal design begins; internals are designed to serve the frozen surface, never the reverse. - Decide, then write: once a stage's frontier is empty and its ADRs are recorded, write that stage's files directly. The user reviews the generated files and requests changes afterward — no draft-approval loops. </HARD-GATE>

Full Scope, One Spec

Capture the complete scope the user wants in this single spec, however large it grows. Agents run long and cy-create-tasks decomposes the work later, so document size is never a reason to trim, defer, or stage anything.

• A capability leaves the spec only when the user decides against it — record that in Non-Goals.
• YAGNI applies to invention: challenge features the user never asked for; keep every one they did.
• When the user adds scope mid-conversation, fold it in and keep going.
• Design minimalism applies to Part II — to the design, never the scope: include no component, interface, or abstraction the design does not strictly need, and prefer adding a file to an existing package over proposing new packages.

Grilling

Read references/grill-protocol.md before the first round and run every grill with its frontier method: map the stage into a design tree, ask the whole frontier each round (numbered questions, each led by a recommendation), dispatch read-only subagents for facts, chase vague answers, challenge vocabulary against docs/_memory/glossary.md, and capture an ADR (per references/adr-template.md) the moment a significant decision crystallizes. A grill is done when its frontier is empty — every branch resolved or explicitly parked in Open Questions with the user's consent.

Required Inputs

• Feature name or product idea.
• Optional: _idea.md at the slug as primary context.
• Optional: existing _spec.md or companions for update mode.

Workflow

Track each step as a task in the runtime's task tracker when one is available, and complete the steps in order.

Stage 1 — Product

1. Resolve the working directory.

   • Derive the slug from the feature name; the target directory is .compozy/tasks/<slug>/ with an adrs/ subdirectory. Create both if missing.
   • Read _idea.md there if present. If _spec.md exists, read it and operate in update mode.

2. Discover context through two parallel research tracks. Both MUST finish before any question is asked; run them in parallel (e.g., two Agent tool calls).

   • Track A — Codebase: files, patterns, data models, and integration points related to the request; summarize in 3-5 bullets.
   • Track B — Market: 3-5 web searches on trends, competing products, and user expectations; summarize in 3-5 bullets. If web search tools are unavailable, note the limitation and proceed with Track A only.
   • Present the merged findings to the user before the first round.

3. Grill the product through the product lens: WHAT users need, WHY it provides value, WHO the users are. When the feature name sounds technical ("webhook notifications"), translate it into the user-experience question behind it ("which events should notify the user?") — implementation questions wait for Stage 2. Done when the product frontier is empty.

4. Write the user-story catalog.

   • Read references/user-stories-template.md and write .compozy/tasks/<slug>/_user_stories.md.
   • Cover every persona — secondary ones included — and every core feature; run the template's edge-case sweep against every story.
   • Done when every story has verifiable acceptance criteria plus edge cases with expected behavior, and every edge-case class has been probed against every story.

5. Write Part I of _spec.md.

   • Read references/spec-template.md and fill every Part I section with the decided direction and confirmed answers; the template carries the per-section rules.
   • Present the Stage 1 summary: decided direction, non-goals, parked questions, file paths.

Checkpoint: proceed to Stage 2 only after the user confirms the Stage 1 summary; fold requested adjustments in first.

Stage 2 — Surface, then internals

6. Explore the architecture: spawn a read-only subagent to map patterns, existing components, dependencies, and technology stack relevant to the design; have it return every load-bearing path annotated with why it matters — repo files, and vendored external sources when they inform the design — as the seed for the File References section. Read every adrs/*.md and analysis/*.md under the slug.

7. Draft the public surface as if the feature already shipped:

   • Read references/dx-template.md and draft .compozy/tasks/<slug>/_dx.md — always.
   • Read references/uiux-template.md and draft .compozy/tasks/<slug>/_uiux.md — only when the feature touches web/ surfaces. Its presence marks the feature UI-bearing for the QA tail.

8. Grill the surface: rounds on the drafts themselves — naming, invocation shape, YAML feel, output ergonomics, golden-path friction, failure copy. Rework the drafts between rounds; the draft is the question. Done when the surface frontier is empty — the surfaces are now frozen.

9. Grill the internals through the technical lens: HOW to implement, WHERE components live, WHICH technologies to use — architecture and component boundaries, data models and storage, integration points, testing strategy. Never spend a question on what the codebase can answer. Done when the technical frontier is empty.

10. Write Part II of _spec.md.

    • Fill every applicable Part II section per the template: map every Part I goal, every story in _user_stories.md, and every surface in _dx.md/_uiux.md to a technical component; reference Part I sections by name without duplicating them.
    • The template carries the six quality markers and the CompozyOS mandatory sections — fill each or state explicit no-impact evidence.
    • Fill File References with every path the design depends on — repo files, vendored external sources, analysis files, design artboards — each with its one-clause read-reason; tasks copy their subsets from this index.
    • List every ADR from both stages in the Architecture Decision Records section; if none exists yet, record the primary-technical-approach ADR first.

11. Write the test contract.

    • Read references/tests-template.md and write .compozy/tasks/<slug>/_tests.md.
    • Derive unit cases from every component and interface in Part II including every error path; integration cases from every component boundary; E2E cases from every journey — CLI/API journeys use the exact commands and routes from _dx.md, browser journeys follow the _uiux.md surface map.
    • Done when the coverage matrix satisfies the template's Coverage Demands and every case meets its Case-Writing Rules.

12. Hand off: confirm every file path to the user, invite change requests directly on the generated files, and point to cy-create-tasks as the next step.

Error Handling

• Insufficient context for a section: note it in Open Questions rather than guessing.
• Web research tools unavailable: proceed with codebase findings and state the limitation.
• Target directory cannot be created: stop and report the filesystem error.
• Conflicting architectural patterns in the codebase: document both and recommend one with rationale.
• Update mode: preserve sections the user has not asked to change, and mirror every behavior or interface change into the affected companions (_user_stories.md, _dx.md, _uiux.md, _tests.md) so the set stays in sync.
