calendar
Verdict safe, but 1 finding (1 medium), mainly social engineering. Most recent scan 2026-02-05.
This skill is a non-functional placeholder that misleadingly advertises calendar management capabilities without any implementation. The primary security concern is social engineering (AITech-2.1) - the skill's description and feature list create false expectations about its capabilities, which could lead users to believe they have calendar integration when they do not. This is a MEDIUM severity issue because it involves deceptive metadata that misrepresents the skill's functionality. Additionally, there are several LOW severity issues related to missing optional metadata fields (license, compatibility, allowed-tools) and unused dependency specifications. No actual security threats like data exfiltration, prompt injection, or command injection are present since there is no executable code. However, the deceptive nature of the skill's claims warrants attention.

Findings
MEDIUM Misleading Description - No Implementation Provided Social Engineeringllm
The skill claims to provide 'Calendar management and scheduling' with features like 'Create events', 'Schedule meetings', 'Set reminders', and 'Calendar sync' across multiple providers (Google Calendar, Apple Calendar, Outlook Calendar). However, no script files or implementation code are provided. This is a deceptive skill that cannot perform any of its advertised functionality. Users may believe they are getting calendar integration capabilities when the skill has no actual implementation.

Features listed: 'Create events, Schedule meetings, Set reminders, View availability, Recurring events, Calendar sync'. Supported Providers: 'Google Calendar, Apple Calendar, Outlook Calendar'.

What we checked
- Static analyzer. Pattern rules over SKILL.md and bundled files: known-bad commands, exfiltration URLs, secrets, obfuscation.
- Behavioral analyzer. Checks what the skill asks the agent to do against what its description claims it does.
- Llm analyzer. A language model reads the skill and reports intent-level issues the rules cannot express.
- Trigger analyzer. Looks for instructions that fire on conditions the user did not ask for.
- Meta analyzer. A second model pass that validates, deduplicates and re-scores the other analyzers' findings.
What we did not check
- Runtime behaviour. The skill was not executed; findings come from reading its files.
- Anything fetched at install or run time, including remote scripts, package dependencies, and URLs the skill tells the agent to open.
- Content the analyzers cannot read: images, binaries, and some non-English text.
- Known scanner bypass classes. See the methodology and limitations page.
