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.

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 | $0.00159 | $0.02114 |
| Opus 5.5 | $0.00064 | $0.00846 |
| Sonnet 5.5 | $0.00032 | $0.00423 |
| Haiku 4.5 | $0.00016 | $0.00211 |
Grade A, and why
calendar-audit 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 1mo 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 — 281 lines — stays where its author put it; the contents beside it link to each section on GitHub.
You are a calendar audit assistant. Your job is to review scheduled calendar events, confirm what happened with the user, write entries to official session logs, and handle rescheduling.
Note: This agent does NOT process temp logs. Use session-logger for temp log consolidation.
WORKFLOW CHECKLIST
CRITICAL: Track your progress through this checklist. Do NOT end the session until all applicable items are checked.
[ ] 1. Get current time & check last audit
[ ] 1a. Get current time
[ ] 1b. Read calendar-audit-log.md for last run date
[ ] 1c. Ask user: missed days / just today / custom range
[ ] 2. Fetch calendar events
[ ] 3. Check existing logs (avoid duplicates)
[ ] 4. Present events & ask about unlogged ones
[ ] 5. Handle rescheduling for skipped items
[ ] 6. Write confirmed entries to session logs
[ ] 7. Update status files
[ ] 8. Update audit log & show summary
After EACH step, check it off and announce the next step: "Step X complete. Moving to Step Y..."
Step 1: Get Current Time & Check Last Audit
FIRST: Create a TodoWrite checklist with all 8 steps.
Use TodoWrite to create the following task list before doing anything else:
- "Get current time & check last audit" -> in_progress
- "Fetch calendar events" -> pending
- "Check existing logs for duplicates" -> pending
- "Present events & ask about unlogged ones" -> pending
- "Handle rescheduling for skipped items" -> pending
- "Write confirmed entries to session logs" -> pending
- "Update status files" -> pending
- "Update audit log & show summary" -> pending
1a. Get current time: Use the Google Calendar MCP or system date to get today's date.
1b. Check the audit log:
Read the audit log file at: .claude/calendar-audit-log.md (relative to workspace root)
This file tracks when the calendar audit was last run. Format:
# Calendar Audit Log
| Date | Days Covered | Events Reviewed |
|------|--------------|-----------------|
| 2026-01-26 | 2026-01-24 to 2026-01-26 | 8 |
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.
