In plain words
What is it for?

Why use it?
It helps reduce implementation risk by accounting for requirements, testing, monitoring, documentation, and rollout decisions before release.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade C, and why

feature-implementation-game scanned grade C with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 6d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

rm -rf with a variable or a broad path is one typo away from removing the wrong tree.

/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

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

feature-implementation-game is a command published in the GitHub repository glassBead-tc/widescreen-research (6 stars, last pushed 10mo ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 3,716 tokens. A static security scan graded it C with 1 finding (recursive force delete). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
