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.

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 | $0.00146 | $0.01613 |
| Opus 5 | $0.00073 | $0.00807 |
| Sonnet 5 | $0.00029 | $0.00323 |
| Haiku 4.5 | $0.00015 | $0.00161 |
Grade A, and why
managing-reminders 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 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.
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.

Managing reminders
This skill guides you through creating and managing PostHog reminders. A reminder is a private, human-paced nudge to yourself: it fires an in-app notification on a schedule, with no condition attached. It can optionally link to a PostHog resource.
When to use this skill
Use this skill when the user:
- Says "remind me to…", "nudge me", "ping me", or "don't let me forget"
- Wants a one-off reminder at a specific date/time
- Wants a recurring reminder (every day, weekly, every Monday, weekdays, monthly, etc.)
- Wants to be reminded to review a specific dashboard, insight, experiment, flag, survey, notebook, replay, or error
- Wants to see, change, or cancel reminders they have set
Reminder vs alert vs subscription
These three look similar but solve different jobs. Pick the right one:
- Reminder — a human-paced nudge to yourself with no condition. It just fires an in-app notification on a schedule ("remind me to review the launch dashboard every Monday"). If the user says "remind me to…", it is a reminder.
- Alert — watches an insight's metric on a schedule and notifies only when a threshold or anomaly condition is met ("tell me if signups drop below 100").
- Subscription — delivers an insight or dashboard export/snapshot on a schedule via email, Slack, or webhook ("email me this dashboard every morning").
If there is a condition to evaluate, it is an alert. If there is an export to deliver, it is a subscription. If it is just a timed nudge to a person, it is a reminder.
Scheduling shapes
A reminder uses exactly one of scheduled_at, recurrence_interval, or cron_expression.
Providing zero or more than one is rejected.
One-off
Set scheduled_at to a future ISO 8601 timestamp. The reminder fires once, then becomes completed.
| User says | Field |
|---|---|
| "remind me tomorrow at 3pm" | scheduled_at: <tomorrow 15:00 in the user's tz> |
| "remind me on Jan 5 at 9am" | scheduled_at: "2026-01-05T09:00:00" (+ timezone) |
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.

managing-reminders is a skill published in the GitHub repository PostHog/posthog-foss (715 stars, last pushed today), licensed MIT. It adds 146 tokens to every session and 1,613 once invoked, about $0.0007 per session on Opus 5. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-09-03.
