Install in OpenClaw
/install caldav-calendar
Description
Sync and query CalDAV calendars (iCloud, Google, Fastmail, Nextcloud, etc.) using vdirsyncer + khal. Works on Linux.
Usage Guidance
Install this only if you are comfortable letting the agent use vdirsyncer and khal with your calendar account. Use an app password or limited-scope credential where possible, restrict permissions on credential and calendar cache files, and review create/edit/delete commands before syncing changes to the remote calendar.
Capability Analysis
Type: OpenClaw Skill
Name: caldav-calendar
Version: 1.0.1
The skill bundle is designed for CalDAV calendar synchronization and management using `vdirsyncer` and `khal`. All commands and instructions in `SKILL.md` are directly related to the stated purpose, such as syncing, listing, creating, editing, and deleting calendar events, as well as managing local cache files. The configuration examples, including the use of `cat` to fetch a password for `vdirsyncer`, describe standard functionality of the tools and do not indicate an attempt at data exfiltration or malicious execution by the skill itself. There is no evidence of prompt injection, obfuscation, or other harmful behaviors.
Capability Assessment
Purpose & Capability
The stated purpose is CalDAV calendar sync and querying via vdirsyncer and khal, and the artifact instructions match that purpose, including viewing, creating, editing, deleting, and syncing events.
Instruction Scope
Commands are explicit examples and setup steps rather than hidden automation; event mutations and deletes are high-impact calendar actions but are clearly tied to user-directed use of khal.
Install Mechanism
The package contains only SKILL.md and declares apt installation of vdirsyncer and khal, with no executable scripts, obfuscated payloads, or custom installer behavior.
Credentials
The skill needs CalDAV credentials and stores synced calendar files locally, which is expected for this integration but exposes private calendar data if local files or credential files are poorly protected.
Persistence & Privilege
Persistence is limited to normal vdirsyncer local calendar files, status data, and the khal cache; there is no evidence of background workers, startup hooks, privilege escalation, or hidden persistence.
How to Use
- Make sure OpenClaw is installed (local or Docker)
- Run the install command in chat:
/install caldav-calendar - After installation, invoke the skill by name or use
/caldav-calendar - Provide required inputs per the skill's parameter spec and get structured output
