安全使用建议
This skill is internally consistent for date/time tasks and doesn't ask for credentials or external installs. Before enabling it, confirm the agent runtime will (1) actually run shell commands only within a restricted context, (2) properly escape or validate any user-supplied date/time strings before interpolating them into shell commands to avoid command injection, and (3) grant the skill only the minimal shell privileges needed. Also test on your target OS because date command behavior differs across platforms (the skill provides cross-platform reference files and safe schemes for GNU date month/year adjustments). If you cannot ensure safe shell invocation or input sanitization, consider rejecting or sandboxing the skill.
功能分析
Type: OpenClaw Skill
Name: time-calc
Version: 1.0.0
The skill provides a framework for date and time calculations by instructing the AI agent to execute shell and PowerShell commands across different platforms. While the logic in SKILL.md and the reference files (linux.md, macos.md, windows.md) is technically sound and aligned with the stated purpose, the design pattern of constructing shell commands from user-provided strings (e.g., dates and offsets) without explicit sanitization instructions introduces a significant risk of shell injection. The use of complex nested command substitutions and arithmetic expansion in the Linux and macOS reference files further increases the attack surface for potential RCE if the agent is manipulated via prompt injection.
能力评估
Purpose & Capability
Name/description (time/date arithmetic and parsing) match the actual contents: an instruction-only skill that runs platform-specific shell commands (BSD/GNU/PowerShell) using the included references. It does not request unrelated credentials, binaries, or config paths.
Instruction Scope
SKILL.md instructs the agent to detect the platform, read the skill's own reference files ($SKILL_ROOT/references/*.md), and execute shell commands to compute times. This is appropriate for the stated purpose, but because the runtime executes shell commands constructed from user inputs, there is an implementation risk: user-provided strings must be safely validated/escaped to avoid command injection. The skill itself documents safe handling for month/year arithmetic (GNU date overflow handling).
Install Mechanism
No install spec and no code files beyond documentation — lowest-risk model. Nothing is downloaded or written to disk by an installer.
Credentials
The skill requires no environment variables, credentials, or external config paths beyond reading its own bundled reference files. Requested access is proportional to its function.
Persistence & Privilege
always:false and user-invocable:true; the skill does not request permanent presence or attempt to modify other skill/system settings. Autonomous invocation is allowed (platform default) but not excessive here.

版本历史
v1.0.0
time-calc v1.0.0 Initial Release
- Provides 7 atomic operations for date/time calculation and parsing: current time, date info, relative weekday, add/subtract, difference, timezone conversion, and Unix timestamp conversion.
- Directly invokes platform-specific shell commands for all operations; no mental math or external dependencies required.
- Supports smart parsing of user queries (e.g., “明天”, “下周三”, “3天后”) and maps to corresponding time calculation.
- Handles complex corner cases like month-end adjustment for date arithmetic and correct weekday calculation per ISO week.
- Cross-platform: macOS, Linux (WSL), and Windows PowerShell supported, with detailed platform references for each operation.
- Fully user-invocable for a wide variety of everyday and technical date/time questions.
