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 | $0.00033 | $0.00847 |
| Opus 5 | $0.00016 | $0.00424 |
| Sonnet 5 | $0.00007 | $0.00169 |
| Haiku 4.5 | $0.00003 | $0.00085 |
Grade A, and why
add-morning-briefing scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 11d ago.
A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.
Nothing flagged
None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.
How it starts
The opening of the file, as written. The whole thing — 92 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Add Morning Briefing
Registers scheduled tasks that run the agent with specific prompts on a cron. No code changes needed — this skill just creates IPC task files.
Setup
1. Ask the user
Use AskUserQuestion to understand what they want:
- Which briefings? Morning summary / Weekly review / Both / Custom
- What time? Default: 8am weekdays for morning, 5pm Friday for weekly
- What to include? Weather, email, PRs, news, calendar, custom checks
- Location? For weather (default: London)
2. Register the tasks
For each briefing, write an IPC task file to data/ipc/main/tasks/.
Find the main group's chat JID first:
sqlite3 store/messages.db "SELECT jid FROM registered_groups WHERE folder = 'main' LIMIT 1;"
Morning Briefing (weekdays at 8am)
CHAT_JID="tg:414798121" # Replace with actual JID
cat > data/ipc/main/tasks/morning_$(date +%s).json << EOF
{
"type": "schedule_task",
"prompt": "Morning briefing. Be concise — 5 lines max.\n\n1. Check the weather for London today\n2. Check Gmail for anything urgent in the last 12 hours\n3. Check for open PRs on my GitHub repos (gh pr list)\n4. Any scheduled tasks that failed overnight (check task_run_logs in the database)\n\nFormat as a quick summary. No greetings, no sign-off.",
"schedule_type": "cron",
"schedule_value": "0 8 * * 1-5",
"context_mode": "isolated",
"targetJid": "$CHAT_JID"
}
EOF
Weekly Review (Friday at 5pm)
cat > data/ipc/main/tasks/weekly_$(date +%s).json << EOF
{
"type": "schedule_task",
"prompt": "Weekly review. Check conversations/ folder for this week's conversation archives. Summarise:\n\n1. What we worked on this week\n2. What's still open or unfinished\n3. What to focus on next week\n\nKeep it to 10 lines. No fluff.",
"schedule_type": "cron",
"schedule_value": "0 17 * * 5",
"context_mode": "isolated",
"targetJid": "$CHAT_JID"
}
EOF
3. Customise the prompts
Adjust prompts based on user answers from step 1. Common additions:
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.
