Specification Quality Checklist: Agent Skills Support for Codex and Vibe

Purpose: Validate specification completeness and quality before proceeding to planning Created: 2026-04-14 Feature: spec.md

Content Quality

  • ✅ No implementation details (languages, frameworks, APIs)
  • ✅ Focused on user value and business needs
  • ✅ Written for non-technical stakeholders
  • ✅ All mandatory sections completed

Note on implementation detail: The spec references specific filesystem paths (.agents/skills/, .codex/prompts/, .vibe/), binary names (vibe), and registry names (AGENT_SKILL_CONFIG, AI_CHOICES). These are intrinsic to the feature — the observable contract between Spec Kitty and the external Vibe/Codex CLIs is literally "write these named files into these named directories." They are user-visible integration surfaces, not internal implementation choices, and the acceptance scenarios would be untestable without them. No code-level structure, framework, or language choice is prescribed.

Requirement Completeness

  • ✅ No [NEEDS CLARIFICATION] markers remain
  • ✅ Requirements are testable and unambiguous
  • ✅ Requirement types are separated (Functional / Non-Functional / Constraints)
  • ✅ IDs are unique across FR-###, NFR-###, and C-### entries
  • ✅ All requirement rows include a non-empty Status value
  • ✅ Non-functional requirements include measurable thresholds
  • ✅ Success criteria are measurable
  • ✅ Success criteria are technology-agnostic (no implementation details)
  • ✅ All acceptance scenarios are defined
  • ✅ Edge cases are identified
  • ✅ Scope is clearly bounded
  • ✅ Dependencies and assumptions identified

Feature Readiness

  • ✅ All functional requirements have clear acceptance criteria
  • ✅ User scenarios cover primary flows
  • ✅ Feature meets measurable outcomes defined in Success Criteria
  • ✅ No implementation details leak into specification

Notes

  • P0 research validated the user's suspicion that Codex's current integration (.codex/prompts/) uses a path OpenAI has deprecated in favor of Agent Skills discovered from .agents/skills/. This reshaped the mission from "add Vibe" to "add Vibe + modernize Codex onto the same Agent Skills renderer."
  • Constraint C-005 forbids a Mistral-only code path: the renderer must be generic and Codex must be the second native consumer in the same release. This guards against shipping a one-off Vibe integration next to a legacy Codex one.
  • Skill Ownership Manifest format is intentionally left open for the plan phase. The spec only requires that ownership be trackable with no false positives; format and location are implementation decisions.
  • Vendor-specific skill roots (.vibe/skills/, ~/.codex/skills/) are explicitly out of scope for this release. Users can follow up in a later mission if demand warrants.
