Usage Guidance
This skill appears internally consistent and limited to doing tax math — it does not install code or request credentials. It is still an estimator, not professional tax advice: do not share sensitive identity documents (e.g., National Insurance numbers, bank account details) in free-text prompts, and verify critical filings or large tax decisions with HMRC or a qualified accountant. If you rely on it for recurring reporting (MTD), periodically confirm the rates/thresholds it uses match official HMRC updates.

Capability Assessment
Purpose & Capability
Name/description (UK tax calculator & MTD prep) align with the runtime instructions: computing taxable profit, Income Tax (including PA taper), Class 2/4 NI, VAT threshold checks, and MTD summaries. No unrelated permissions, binaries, or services are requested.
Instruction Scope
SKILL.md consists of calculation rules, thresholds, expense categories, output templates, and interaction modes. It does not instruct the agent to read files, access system config, call external endpoints, or exfiltrate data. The guidance is narrowly scoped to tax calculation and user-provided inputs.
Install Mechanism
No install spec or code files that would be written to disk or executed. Instruction-only skill — lowest install risk.
Credentials
No environment variables, credentials, or config paths are required. The data needed (income, expenses) is exactly what the skill's purpose implies.
Persistence & Privilege
Skill is user-invocable, not marked always:true, and does not request modification of other skills or system settings. Autonomous invocation is allowed by platform default but there are no additional privileges requested.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install uk-tax-calculator - After installation, invoke the skill by name or use
