Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

SkillSpector: 4 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 →

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.
| Model | Per session | Once invoked |
|---|---|---|
| Fable 5.1 | $0.00035 | $0.01483 |
| Opus 5 | $0.00017 | $0.00741 |
| Sonnet 5 | $0.00007 | $0.00297 |
| Haiku 4.5 | $0.00003 | $0.00148 |
Grade B, and why
dual-channel-watchexec scanned grade B with 2 findings 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 12d 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.
Sends data to an external URLmediumData exfiltration
A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

Dual-Channel Watchexec Notifications
Send reliable notifications to both Telegram and Pushover when watchexec detects file changes or process crashes.
Self-Evolving Skill: This skill improves through use. If instructions are wrong, parameters drifted, or a workaround was needed — fix this file immediately, don't defer. Only update for real, reproducible issues.
When to Use This Skill
Use this skill when:
- Setting up file change monitoring with notifications
- Implementing process crash alerting via Telegram and Pushover
- Creating watchexec wrappers with dual-channel notification support
- Formatting messages for both HTML (Telegram) and plain text (Pushover)
- Troubleshooting notification delivery or formatting issues
Core Pattern
watchexec wrapper script → detect event → notify-script → Telegram + Pushover
# wrapper.sh - Monitors process and detects restart reasons
watchexec --restart -- python bot.py
# On event, call:
notify-script.sh <reason> <exit_code> <watchexec_info_file> <crash_context>
Critical Rule: Format Differences
Telegram: HTML mode ONLY
MESSAGE="<b>Alert</b>: <code>file.py</code>"
# Escape 3 chars: & → &, < → <, > → >
Pushover: Plain text ONLY
/usr/bin/env bash << 'SKILL_SCRIPT_EOF'
# Strip HTML tags before sending
MESSAGE_PLAIN=$(echo "$MESSAGE_HTML" | sed 's/<[^>]*>//g')
SKILL_SCRIPT_EOF
Why HTML for Telegram:
- Markdown requires escaping 40+ chars (
.,-,_, etc.) - HTML only requires escaping 3 chars (
&,<,>) - Industry best practice
Quick Reference
Send to Both Channels
/usr/bin/env bash << 'SKILL_SCRIPT_EOF_2'
# 1. Build HTML message for Telegram
MESSAGE_HTML="<b>File</b>: <code>handler_classes.py</code>"
# 2. Strip HTML for Pushover
MESSAGE_PLAIN=$(echo "$MESSAGE_HTML" | sed 's/<[^>]*>//g')
# 3. Send to Telegram with HTML
curl -s -d "chat_id=$CHAT_ID" \
-d "text=$MESSAGE_HTML" \
-d "parse_mode=HTML" \
https://api.telegram.org/bot$BOT_TOKEN/sendMessage
# 4. Send to Pushover with plain text
curl -s --form-string "message=$MESSAGE_PLAIN" \
https://api.pushover.net/1/messages.json

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.

dual-channel-watchexec is a skill published in the GitHub repository terrylica/cc-skills (73 stars, last pushed today), licensed MIT. It adds 35 tokens to every session and 1,483 once invoked, about $0.0002 per session on Opus 5. A static security scan graded it B with 2 findings (sends data to an external url, makes network calls). No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
