nexo_schedule_add

Add a personal cron job that automatically creates a LaunchAgent (macOS) or systemd timer (Linux) with execution tracking.

Instructions

Add a new personal cron job. Creates LaunchAgent (macOS) or systemd timer (Linux) automatically, wrapped with execution tracking.

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
cron_idYesUnique ID for this cron (e.g. 'my-backup', 'report-daily'). Must be lowercase with hyphens.
scriptYesPath to the script to run (absolute or relative to personal/scripts/).
scheduleNoTime-based schedule as 'HH:MM' (daily) or 'HH:MM:weekday' (e.g. '08:00:1' for Monday 8AM). Mutually exclusive with interval_seconds.
interval_secondsNoRun every N seconds (e.g. 300 for every 5 min). Mutually exclusive with schedule/keep_alive.
descriptionNoWhat this cron does (for logs and status).
script_typeNo'auto' (default), 'python', 'shell', 'node', or 'php'.auto
keep_aliveNoRun as a daemon/keep-alive service instead of a timer.
Behavior3/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

No annotations provided. Description reveals automatic platform detection and execution tracking, but does not address failure scenarios, conflict handling, or permissions.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

Single concise sentence with no redundancy. Straightforward and easy to parse.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness3/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Adequate for a 7-parameter tool with no output schema, but lacks details on return values, error cases, and differentiation from personal vs core schedules.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters3/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

All parameters have descriptions in schema (100% coverage), so description adds no extra meaning beyond the schema. Baseline 3 is appropriate.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

Clearly states verb 'Add' and resource 'personal cron job', with specific mention of platform automation (LaunchAgent/systemd timer) and execution tracking, distinguishing it from other scheduler tools.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines3/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

No explicit guidance on when to use this tool versus alternatives like nexo_core_schedule_set or nexo_personal_script_schedules. Usage is implied but not clarified.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
