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.

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.

It reduces scope creep by recording the desired work, exclusions, decisions, and completion criteria before coding starts.

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add AlexZio00/sovereign-skills --skill scope

Clone the repo

git clone --depth 1 https://github.com/AlexZio00/sovereign-skills

Made for: Claude Code, Codex.

Or install scope, the plugin that ships this one along with the rest of its 1 skill.

Security scan A 0 findings. A grade says what 26 rules found in the file — not that it is safe. Third-party audits

NVIDIA SkillSpector warn 7 Sept 2026

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.

Model	Per session	Once invoked
Fable 5.1	$0.00115	$0.05257
Opus 5.5	$0.00046	$0.02103
Sonnet 5.5	$0.00023	$0.01051
Haiku 4.5	$0.00012	$0.00526

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 4d ago.

The scan reads SKILL.md. This mod also ships 4 executable files (scripts/ambiguity_gate.py, scripts/coverage_check.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.

scope/SKILL.md · 301 lines

How it starts

The opening of the file, as written. The whole thing — 301 lines — stays where its author put it; the contents beside it link to each section on GitHub.

/scope — Scope Definition Engine

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. Chain: scope (define) → freeze (declare the editable zone) → goal-lock (execute). Each step reads the saved file or block of the one before; see Output.

${CLAUDE_SKILL_DIR} is this skill's folder; Claude Code fills it in. In other agents, replace it with the path where you installed the skill. Use python instead of python3 where only that exists (common on Windows). Paths of the user's own files (BRIEF.md, spec.md, drafts) are relative to the project root or absolute.

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", "plan this", "define the scope", "write a spec"
Equivalent phrases in the user's language (see the frontmatter trigger list)

Discard If

Bug fix, 1-file edit → implement directly
BRIEF.md/spec.md already exists → use Edit
Exploration only → plain conversation, or a brainstorming agent (optional, not included in this repo)

Key Assumptions

Project CLAUDE.md exists (existing projects) — if broken: can't auto-scan constraints, write from user input only.
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?"

What ships with it

6 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 (157 stars, last pushed yesterday), licensed MIT. It adds 115 tokens to every session and 5,257 once invoked, about $0.0005 per session on Opus 5.5. 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.
