Description
Calculate addition expressions from user input, including integers, decimals, and negative numbers, and return concise step-by-step results.
README (SKILL.md)
Overview
Use this skill when the user asks for addition calculations.
When to Use
- User asks to add two or more numbers.
- User inputs expressions like
3 + 5,1.2 + 3.4 + 5,-2 + 9.
Scope
- Supported: addition only.
- Not supported: subtraction, multiplication, division, equations, symbolic algebra.
Input Handling
- Accept numbers separated by
+, spaces, commas, or Chinese wording (for example:加). - Normalize full-width symbols to half-width symbols before parsing.
Workflow
- Extract all numeric values from user input.
- Verify at least two valid numbers are present.
- Compute the sum.
- Return:
- Parsed numbers
- Expression
- Final result
Output Format
Always return:
- Expression used
- Result
- Optional one-line check
Example:
- Expression:
1.2 + 3.4 + 5 - Result:
9.6
Safety and Accuracy Rules
- Do not invent missing numbers.
- If input is ambiguous, ask user to rewrite in explicit form.
- Preserve decimal precision as entered when reasonable.
Usage Guidance
This skill appears safe and coherent: it only parses user text for numbers and returns an addition expression and result. Before installing, consider if you need more features (e.g., other operations, higher-precision arithmetic, or explicit locale handling for commas/full-width digits). Test with representative inputs (negative numbers, decimals, localized wording) to confirm parsing matches your expectations. If you require cryptographic-level precision or auditing for financial use, prefer a library or skill that documents numeric precision guarantees.
Capability Analysis
Type: OpenClaw Skill
Name: addition-assistant-skill
Version: 1.0.4
The skill is a simple addition utility designed to parse and sum numbers from user input. The instructions in Skill.md and the test prompts in TEST_PROMPTS.md are entirely consistent with the stated purpose and contain no executable code, network requests, or suspicious prompt-injection attempts.
Capability Assessment
Purpose & Capability
The name/description (addition helper) match the SKILL.md instructions: parsing numeric inputs and summing them. There are no unrelated env vars, binaries, or install steps requested.
Instruction Scope
The SKILL.md stays narrowly scoped to parsing and summing numbers (including decimals and negatives), asking clarifying questions for ambiguity, and returning a concise expression/result. It does not instruct reading files, accessing system state, or sending data to external endpoints.
Install Mechanism
No install spec or code is provided (instruction-only), so nothing is downloaded or written to disk. This is the lowest-risk installation model.
Credentials
The skill requires no environment variables, credentials, or config paths — appropriate for a simple arithmetic helper.
Persistence & Privilege
always is false and the skill does not request persistent system presence or modify other skills. Autonomous invocation is allowed (platform default) but is not combined with any other risky permission.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install addition-assistant-skill - After installation, invoke the skill by name or use
/addition-assistant-skill - Provide required inputs per the skill's parameter spec and get structured output
Version History
v1.0.4
Addition Assistant 1.0.4
- Improved input handling for numbers separated by commas, spaces, and Chinese wording (e.g., "加").
- Normalizes full-width symbols to half-width for accurate parsing.
- Outputs clear, step-by-step addition results, including expression and final sum.
- Supports addition of integers, decimals, and negative numbers exclusively.
- Ensures only valid addition requests are processed; prompts user for clarification if input is ambiguous.
