moscow

moscow is a skill for Claude Code, Codex from tupe12334/instinct. It costs 24 tokens per session (1,672 once invoked), scanned A, original, MIT.

A scope-prioritization method with four categories: Must Have, Should Have, Could Have, and Won’t Have. It is commonly called MoSCoW prioritization.

In plain words
What is it for?
Use it to sort product requirements or features before delivery planning and decide what must ship when time or budget is limited.
Why use it?
It makes trade-offs explicit and limits scope creep by showing what is required, optional, or excluded from a 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 A, and why

moscow scanned grade A with 0 findings 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 5d 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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

MoSCoW Prioritization

Overview

MoSCoW sorts requirements or features into four buckets that define what ships in a given release. It forces explicit trade-off decisions before work starts, preventing scope creep and last-minute cuts.

┌────────────────────────────────────────────────────────────┐
│  M — Must Have    │ Non-negotiable. Release fails without  │
│                   │ it. No workaround exists.              │
├────────────────────────────────────────────────────────────┤
│  S — Should Have  │ High value. Painful to omit but        │
│                   │ a workaround exists short-term.        │
├────────────────────────────────────────────────────────────┤
│  C — Could Have   │ Nice-to-have. Include only if time     │
│                   │ and budget allow. Drop first.          │
├────────────────────────────────────────────────────────────┤
│  W — Won't Have   │ Explicitly out of scope this cycle.    │
│                   │ Documented, not forgotten.             │
└────────────────────────────────────────────────────────────┘

Category Definitions

Must Have

The minimum viable product for this release. If any Must is missing, the release must not ship. Apply the test: "Would a reasonable user/stakeholder refuse the release without this?" If yes — Must. Common examples: legal compliance, core user journey, safety-critical paths.

Should Have

Important requirements with a workaround. Users feel the absence but can cope temporarily. These typically ship in the next sprint or release. Common examples: search filters, email notifications, export to PDF.

Could Have

Desirable but low impact relative to effort. They're the first items cut when scope pressure hits. Common examples: UI polish, convenience shortcuts, non-default themes.

Won't Have (this time)

Explicitly de-scoped for this cycle. Writing it down prevents the item from re-entering scope informally or being assumed by stakeholders. It is not "rejected forever" — it is deferred and visible.

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.
