scope

scope is a skill for Claude Code, Codex from AlexZio00/sovereign-skills. It costs 115 tokens per session (3,711 once invoked), scanned A, original, MIT.

A planning skill that defines what a development task includes and excludes before implementation begins. It can create a short brief or a more detailed specification.

In plain words
What is it for?
It is for turning a requirement into a BRIEF.md or spec.md file. It is not intended for simple bug fixes or one-file edits.
Why use it?
It reduces scope creep by recording the desired work, exclusions, decisions, and completion criteria before coding starts.

SkillSpector: 4 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Anti-Refusal · line 241
    Skill instructs the agent to omit warnings, disclaimers, or ethical commentary. Stripping safety caveats hides risk from the user and is a common jailbreak preamble.
    Fix: Remove instructions that suppress warnings, disclaimers, or ethical commentary. Let the agent surface safety-relevant caveats to the user.
  • medium Excessive Agency · line 244
    Skill enables autonomous high-impact decisions without human-in-the-loop verification. Critical operations (destructive commands, financial transactions, data deletion) should require explicit user confirmation.
    Fix: Add human-in-the-loop confirmation for destructive, irreversible, or high-impact operations. Never auto-execute commands that modify files, send data, or alter system state.
  • medium Rogue Agent · line 123
    Skill establishes unauthorized persistence across sessions via cron jobs, startup scripts, or state files. Session persistence allows an attacker to maintain access beyond the current interaction.
    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

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

scope 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 3d ago.

The scan reads SKILL.md. This mod also ships 2 executable files (scripts/ambiguity_gate.py, scripts/test_ambiguity_gate.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

How it starts

The opening of the file, as written. The whole thing — 263 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/scope — Scope Definition Engine v1.0

Unified brief + specify. Lock down "what you will do and what you will NOT do" before implementation. Quick (default) = IN/OUT lock + BRIEF.md. Full = L0→L4 layer chain + spec.md.

Dominant Variable

Is the Scope OUT section explicitly written? — IN alone causes scope creep during implementation. OUT must be explicit to lock it. In Full mode, additionally L2 decision clarity is the dominant variable.

Trigger

  • /scope (Quick default)
  • /scope full (Full mode)
  • /brief (Quick backward compat)
  • /specify (Full backward compat)
  • "scope this", "스펙 잡아줘", "범위 잡아줘", "기획 정리해줘"
  • "spec 만들어", "스펙 만들어", "plan this"

Discard If

  • Bug fix, 1-file edit → implement directly
  • BRIEF.md/spec.md already exists → use Edit
  • Exploration only → delegate to brainstorming

Key Assumptions

  1. Project CLAUDE.md exists (existing projects) — if broken: can't auto-scan constraints, write from user input only.
  2. User provides idea/requirement in ≥1 sentence — if broken: ask "Tell me in one sentence what to build" once.

Mode Selection

Mode Trigger Output Best For
Quick (default) /scope, /brief BRIEF.md Feature add, clear change
Full /scope full, /specify specs/{name}/spec.md Architecture change, multi-module, complex design

Unsure? Start Quick → if user wants more detail: "Shall we switch to full mode?"


Quick Mode — IN/OUT Brief

Step 1: Detect project

  • Existing project: CLAUDE.md, package.json etc. exist → 2-level Glob + keyword Grep (10-file cap)
  • New project: skip

Step 2: Ambiguity score gating

Score clarity across 4 dimensions (0-10 each), by judgment.

Dimension Check
Function What behavior is being added/changed — are inputs/outputs concrete?
Boundary What is explicitly excluded — is IN/OUT clear?
Verification How is "done" verified — is there a measurable criterion?
Assumptions Any hidden assumptions — dependencies on existing system/data/environment?

What ships with it

4 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

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.

scope is a skill published in the GitHub repository AlexZio00/sovereign-skills (128 stars, last pushed 4d ago), licensed MIT. It adds 115 tokens to every session and 3,711 once invoked, about $0.0006 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
