Skylv Context Aware Scheduler

Context-aware task scheduling with priority management

Security Scan

The skill is internally coherent for a local task scheduler: it includes a Node.js implementation that runs user-specified commands and checks file/time conditions, and it does not ask for unrelated credentials or install external code.

Purpose & Capability

Name/description (context-aware scheduler) match the provided implementation: scheduler.js implements cron/interval/file-watch/time-window/api-ready checks and runs actions. Required env vars/binaries/config paths are none, which is proportionate for a local scheduler.

Instruction Scope

SKILL.md instructs running scheduler.js commands (run/now/watch/list). The code executes arbitrary shell commands (child_process.execSync) using action.command and will read files referenced by triggers/conditions. This behavior is expected for a scheduler, but it means tasks can run any command the user places in tasks.json — review tasks before running and avoid placing secrets in action.env.

Install Mechanism

No install spec — the skill is instruction-only with source files included. All code is present in the package (scheduler.js), so nothing is downloaded at install time.

Credentials

The skill declares no required environment variables or credentials. The code inherits process.env into action execution (expected), and it writes/reads a local state file (.scheduler-state.json). There are no requests for unrelated cloud or service credentials.

Persistence & Privilege

always is false and the skill does not request system-wide changes. It persists state only to a local .scheduler-state.json file and task files the user provides; it does not modify other skills or global agent config.

Assessment

This scheduler is coherent and functions as a local task runner, but it executes whatever shell command you put into tasks.json. Before installing/running: - Inspect tasks.json and do not include commands that upload files, echo secrets, or run destructive operations. - Be cautious about action.env entries — do not store credentials there unless necessary and trusted. - Run the scheduler in a non-privileged directory or sandbox first (e.g., a container) to verify behavior. - Note it creates/reads .scheduler-state.json in the working directory; check its contents if you need to understand api-ready logic. - If you plan to schedule tasks that interact with remote services, ensure those commands themselves are secure and authenticated appropriately.

Schedule tasks based on conditions, not just time. Run when a file changes, API rate limit resets, or time window opens.

Skill Metadata

• Slug: skylv-context-aware-scheduler
• Version: 1.0.0
• Description: Context-aware task scheduler. Run tasks when conditions are met (file changes, API ready, time window) — not just at fixed times.
• Category: platform
• Trigger Keywords: scheduler, cron, schedule, trigger, automation, 定时, 条件触发

What It Does

Unlike a regular cron that runs at fixed times, this scheduler runs tasks when conditions are met:

# Run tasks when triggers are due
node scheduler.js run tasks.json

# Run all tasks immediately (ignore triggers)
node scheduler.js now tasks.json

# Start daemon (checks every 30s)
node scheduler.js watch tasks.json

# List all tasks
node scheduler.js list tasks.json

Example: ClawHub Auto-Publisher

{
  "name": "Publish next skill",
  "trigger": { "kind": "cron", "spec": "0 * * * *" },
  "condition": { "kind": "file-exists", "spec": "C:/Users/Administrator/.qclaw/pending-publish.txt" },
  "action": { "command": "clawhub publish . --slug skylv-x --version 1.0.0" }
}

→ Runs every hour, but only if pending-publish.txt exists.

Example: API Rate Limit Aware

{
  "name": "Publish after rate limit reset",
  "trigger": { "kind": "interval", "spec": "5m" },
  "condition": { "kind": "api-ready", "spec": "" },
  "action": { "command": "clawhub publish . --slug skylv-x --version 1.0.0" }
}

→ Checks every 5 minutes, but only executes when rate limit has reset.
