widescreen-research: Command for Claude Code

/feature-implementation-game

Ship new product capabilities with discipline. An OR-inspired shipping protocol that minimizes risk, preserves developer velocity, and bakes in observability, docs, and rollout strategy from the start.

Usage

/feature-implementation-game $ARGUMENTS [ship_deadline] [risk_level] [rollout_strategy]

Arguments

• $ARGUMENTS (required): High-information feature specification. Paste or reference the spec directly; see Variables below
• ship_deadline (optional): ISO 8601 deadline (default: 1 week from now)
• risk_level (optional): "low" | "medium" | "high" (default: "medium")
• rollout_strategy (optional): "flagged" | "canary" | "dark_launch" | "big_bang" (default: "flagged")
• comments (optional): Additional context/constraints

Variables

• SPEC_DOCUMENT: $ARGUMENTS
  • Accepted forms: inline Markdown PRD/RFC, GitHub/GitLab issue URL, file path, YAML/JSON brief
  • Recommended sections for maximum signal:
    • Problem statement, goals, and non-goals
    • Acceptance criteria and success metrics
    • API/SDK contracts (types, errors, pagination, retries)
    • UX notes or wireframes
    • Non-functional requirements (performance, security, availability)
    • Rollout and rollback constraints
    • Telemetry requirements (metrics, events, traces)
    • Docs & examples scope
