功能描述
Display a beautiful time dashboard showing a live summer countdown to the summer solstice, today's sunrise/sunset times in China (Beijing), and current time...
安全使用建议
This skill appears to be what it claims: a small client-side HTML widget that fetches public API data (USNO and sunrise-sunset) and displays a live countdown/clock. Things to check before using: (1) the SKILL.md example mixes a hard-coded solstice date with a note saying the date should be fetched — prefer fetching the official solstice time at runtime; (2) verify and unify the Beijing coordinates used; (3) implement robust timezone handling by parsing ISO UTC times and converting to UTC+8 rather than adding fixed hours blindly; (4) the widget will make public HTTP requests from users' browsers, which reveals the requester's IP and User-Agent to those APIs — if that matters, host the page server-side or proxy requests; and (5) confirm the APIs allow cross-origin requests from your deployment environment (CORS). No credentials or installs are required.
功能分析
Type: OpenClaw Skill
Name: summer
Version: 1.0.6
The skill is a standard informational dashboard designed to display a summer solstice countdown and sunrise/sunset times for Beijing. It utilizes legitimate public APIs (aa.usno.navy.mil and sunrise-sunset.org) and contains no evidence of data exfiltration, malicious execution, or prompt injection. The code logic in SKILL.md is consistent with its stated purpose.
能力评估
Purpose & Capability
Name/description match the instructions: building an HTML widget that fetches solstice and sunrise data and displays a live clock. The required resources (public HTTP APIs) are consistent with this purpose; no unrelated credentials, binaries, or paths are requested.
Instruction Scope
Instructions stay inside the expected scope (fetch public APIs, render an HTML dashboard, tick every second). Minor inconsistencies exist in the examples: the doc says the solstice time is fetched from aa.usno.navy.mil but the code snippet hard-codes SUMMER; there are slightly different Beijing coordinates used in two places (39.9075/116.3972 vs 39.9042/116.4074). Timezone handling is called out (add 8 hours) but implementers should carefully parse ISO UTC strings rather than naively adding hours to avoid DST/date-edge bugs. These are functional issues, not security problems.
Install Mechanism
Instruction-only skill with no install spec and no code files — lowest-risk installation footprint. The runtime behavior is client-side HTTP requests from the rendered page.
Credentials
No environment variables, credentials, or config paths are requested. The public APIs used do not require secrets, so requested access is proportional.
Persistence & Privilege
always is false and there's no request to modify agent/system configuration or other skills. The skill does not request permanent privileges.

- Updated the description to reference a fetched solstice time, not a hardcoded date/time.
- No code or implementation changes; documentation now clarifies data should be retrieved from the API.
- All other instructions, layout, and visual details remain the same.
v1.0.5
No functional or code changes in this release.
- No file changes detected from previous version.
- Documentation in SKILL.md remains essentially unchanged.
- No new features, bug fixes, or updates introduced.
v1.0.4
- Summer countdown now fetches the official solstice time dynamically from the US Naval Observatory API, rather than using a fixed local datetime.

- All other features, including Beijing sunrise/sunset and the live clock, remain unchanged.
- Documentation and implementation instructions updated to reflect API usage for the solstice timestamp.
v1.0.3
- Updated sunrise-sunset API endpoint to use accurate Beijing coordinates: `lat=39.9075&lng=116.3972` (was previously Hong Kong coordinates).
- All documentation and examples now reflect this coordinate change for Beijing.
- No other functionality or file changes.
v1.0.2
- Corrected the sunrise/sunset data panel to use Beijing's coordinates instead of Hong Kong's.
- Updated API usage instructions and labeling to reflect Beijing location (lat/lng 39.9075, 116.3972).

- Displays today's sunrise, sunset, solar noon, and day length for Beijing, fetching live from the sunrise-sunset API
- Shows current date and a live ticking clock in 24h format
- Color-coded, responsive cards: amber/orange for the countdown, blue/teal for sunrise, gray for current time
- User triggers include any summer countdown, days until summer/solstice, China sunrise/sunset, or time widget requests
