Usage Guidance
This skill is essentially a set of usage instructions for the local calcurse CLI. Before installing: ensure you trust the calcurse binary on the host (verify source/version), be aware that running the skill runs that local binary which will read and modify your calendar data (usually ~/.calcurse), and consider backing up your calendar files if you care about accidental changes. If you are uncomfortable with an agent being able to execute local commands, limit autonomous invocation or require explicit user confirmation before the skill runs commands.
Capability Analysis
Type: OpenClaw Skill Name: calcurse Version: 1.0.0 The skill bundle provides instructions and metadata for using the `calcurse` command-line utility. All commands demonstrated in `SKILL.md` are direct invocations of `calcurse` with its standard arguments for calendar management. There is no evidence of malicious intent, data exfiltration, persistence, prompt injection attempts against the agent, or obfuscation. The `_meta.json` file contains standard metadata, and `SKILL.md` correctly declares the `calcurse` binary as a requirement, which is consistent with the skill's stated purpose.
Capability Assessment
✓ Purpose & Capability
Name, description, and required binary (calcurse) align: the skill simply instructs the agent to invoke the local calcurse CLI for calendar operations. No unrelated services, env vars, or credentials are requested.
ℹ Instruction Scope
SKILL.md contains only calcurse CLI examples (non-interactive queries, adding items) and a note about using a PTY for the TUI. It does not instruct reading unrelated files or external endpoints. Note: invoking calcurse will read/write the user's calendar data (typically in ~/.calcurse) even though no config paths are declared—this is expected for a CLI calendar tool.
✓ Install Mechanism
No install spec (instruction-only). The skill requires the calcurse binary to already be present; nothing is downloaded or written by the skill bundle itself.
✓ Credentials
No environment variables, credentials, or config paths are requested. The lack of declared config paths is acceptable but remember the calcurse binary will use its normal data directory on the host.
✓ Persistence & Privilege
always is false and the skill is user-invocable. It does not request persistent or platform-wide privileges and does not modify other skills.
How to Use
  1. Make sure OpenClaw is installed (local or Docker)
  2. Run the install command in chat: /install calcurse
  3. After installation, invoke the skill by name or use /calcurse
  4. Provide required inputs per the skill's parameter spec and get structured output
