SkillSpector: 5 findings, up to high

These are SkillSpector’s own severities. On a checked sample its high-severity flags on skills were ~96% false positives — a documented command, a public API, a “never do X” rule — so we show them as a caution to read, not a verdict. Why →

  • high Tool Misuse · line 26
    Tool parameters are crafted to achieve unintended or unsafe behavior. Parameter abuse can bypass intended safety checks (e.g. shell=True, --force, dangerous glob patterns).
    Fix: Validate all tool parameters against an allowlist. Reject dangerous parameter values (shell=True, --force, -rf /) and use safe defaults.

    Fix: Remove any persistence mechanisms (cron jobs, startup scripts, state files). Skills should not maintain state across sessions without explicit user consent.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

cron-task-creator scanned grade A with 1 finding against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Cron Task Creator

A skill for creating, managing, and running scheduled automated tasks in Clacky.

Architecture Overview

Storage:
  ~/.clacky/tasks/<name>.md      # Task prompt file (self-contained AI instruction)
  ~/.clacky/schedules.yml        # All scheduled plans (YAML list)
  ~/.clacky/logger/clacky-*.log  # Execution logs (daily rotation)

API Base: http://${CLACKY_SERVER_HOST}:${CLACKY_SERVER_PORT}

Cron-Tasks API (unified — manages task file + schedule together):
  GET    /api/cron-tasks              → list all cron tasks with schedule info
  POST   /api/cron-tasks              → create task + schedule {name, content, cron, enabled?}
  PATCH  /api/cron-tasks/:name        → update {content?, cron?, enabled?}
  DELETE /api/cron-tasks/:name        → delete task file + schedule
  POST   /api/cron-tasks/:name/run    → execute immediately (creates a new session)

Cron Expression Quick Reference

Expression Meaning
0 9 * * 1-5 Weekdays at 09:00
0 9 * * * Every day at 09:00
0 */2 * * * Every 2 hours

0 19 * * * Every day at 19:00
0 8 * * 1 Every Monday at 08:00
0 0 1 * * First day of every month

Field order: minute hour day-of-month month day-of-week


Operations

1. LIST — Show all tasks

curl -s http://${CLACKY_SERVER_HOST}:${CLACKY_SERVER_PORT}/api/cron-tasks

Display each task: name, cron schedule, enabled status, content preview.

If no tasks exist, inform the user and offer to create one or show templates.

Key tip: Remind the user that the Clacky WebUI Task Panel (sidebar → Tasks) also shows all tasks and supports direct management.


2. CREATE — New task

Step 1: Gather required info (only ask for what's missing)

  • What should the task DO? (goal, behavior, output format)
  • How often should it run? (or is it manual-only without a schedule?)
  • Any specific parameters? (URLs, file paths, output location, language)

Changes

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
