Assert — Assertion Patterns Reference

Quick-reference skill for assertion techniques, design-by-contract, and defensive programming patterns.

When to Use

  • Writing precondition checks for function inputs
  • Implementing class invariants and postconditions
  • Choosing between assertions and exceptions
  • Applying design-by-contract methodology
  • Understanding assertion behavior across languages

Commands

intro

scripts/script.sh intro

Overview of assertions — purpose, philosophy, and when to use them vs exceptions.

preconditions

scripts/script.sh preconditions

Precondition patterns: validating inputs, guard clauses, and fail-fast design.

postconditions

scripts/script.sh postconditions

Postcondition patterns: validating outputs and return value contracts.

invariants

scripts/script.sh invariants

Class and loop invariants — maintaining consistent state throughout execution.

languages

scripts/script.sh languages

Assertion syntax and behavior in Python, Java, C, JavaScript, Rust, Go.

contracts

scripts/script.sh contracts

Design-by-contract methodology — Bertrand Meyer's approach and modern implementations.

antipatterns

scripts/script.sh antipatterns

Common assertion mistakes: side effects, catching AssertionError, using in production flow.

strategies

scripts/script.sh strategies

Assertion strategies for different contexts: unit tests, production code, APIs, libraries.

help

version

scripts/script.sh version

安全使用建议
This skill appears to be a local, read-only reference implemented as a shell script that prints documentation. If you want maximum assurance, open and inspect scripts/script.sh yourself (it’s included) to verify there are no hidden network calls or commands beyond printing text; otherwise it is reasonable to install and use. Also note that when invoked the agent will run the script locally (normal behavior) — no credentials or external installs are required.
功能分析
Type: OpenClaw Skill Name: assert Version: 1.0.0 The 'assert' skill is a purely educational reference tool providing information on assertion patterns, design-by-contract, and defensive programming. The 'scripts/script.sh' file contains only static text output via heredocs (cat << 'EOF') for various informational commands, and 'SKILL.md' contains standard instructions for an AI agent without any signs of prompt injection or malicious intent.
能力评估
✓ Purpose & Capability
Name/description match the provided content: SKILL.md documents assertion patterns and the included scripts/script.sh prints reference material. No unrelated credentials, binaries, or install steps are requested.
✓ Instruction Scope
Runtime instructions simply invoke scripts/script.sh with a single subcommand (intro, preconditions, etc.). The script prints documentation via here-docs; the SKILL.md does not instruct reading unrelated files, accessing environment secrets, or contacting external endpoints.
✓ Install Mechanism
No install specification; the skill is delivered as an instruction file plus a local shell script. No external downloads, package installs, or archive extraction are requested.
✓ Credentials
The skill declares no required environment variables, credentials, or config paths. The included shell script does not reference credentials or environment secrets in the provided content.
✓ Persistence & Privilege
always is false and the skill does not request elevated or persistent presence. It does not modify other skills or system-wide configuration based on the provided files.
如何使用
