Getting it into your agent

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 | $0.00068 | $0.01775 |
| Opus 5 | $0.00034 | $0.00888 |
| Sonnet 5 | $0.00014 | $0.00355 |
| Haiku 4.5 | $0.00007 | $0.00178 |
Grade A, and why
time-menu 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 7d 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.

On Invocation
When this skill activates, use AskUserQuestion to present the user with a menu:
Question: "What would you like to check?" Header: "Father Time" Options:
-
Label: "Session" Description: "Session health, context usage, compaction risk, and session timer"
-
Label: "Time & Pacing" Description: "Peak hour status, rate limit forecast, and daily briefing"
-
Label: "Work Patterns" Description: "Activity patterns analysis and focus mode timer"
-
Label: "Settings" Description: "Enable/disable time injection for this session"
The user can also select "Other" to ask a free-form question.
If the user invoked this skill WITH a specific question (e.g., "how's my session health?"), skip the menu and go directly to the relevant capability.
After Menu Selection
If "Session" is selected
Ask a follow-up with AskUserQuestion:
Question: "What session info do you need?" Header: "Session" Options:
-
Label: "Current Session" Description: "Health check for THIS session only"
-
Label: "All Sessions" Description: "Health check across all active projects"
-
Label: "Session Timer" Description: "How long the current session has been running"
-
Label: "Context Budget" Description: "Estimate token cost of a file or directory before reading it"
Then run the appropriate capability below.
If "Time & Pacing" is selected
Ask a follow-up with AskUserQuestion:
Question: "What time info do you need?" Header: "Time" Options:
-
Label: "Peak Hours" Description: "Current peak/off-peak status with countdown"
-
Label: "Pace Check" Description: "Rate limit usage estimate and forecast"
-
Label: "Daily Brief" Description: "Morning overview with peak status, patterns, and recommendations"
Then run the appropriate capability below.
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.

time-menu is a skill published in the GitHub repository AfterRealm/father-time (6 stars, last pushed 4mo ago), licensed MIT. It adds 68 tokens to every session and 1,775 once invoked, about $0.0003 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 2026-08-31.
