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 | $0.00095 | $0.00757 |
| Opus 5 | $0.00048 | $0.00378 |
| Sonnet 5 | $0.00019 | $0.00151 |
| Haiku 4.5 | $0.00010 | $0.00076 |
Grade A, and why
temporal-awareness 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 5d 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.

The opening of the file, as written. The whole thing — 59 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Temporal Awareness
The temporal-core plugin gives you a lightweight sense of time passing within a Claude Code session. This skill teaches you how to use those signals well.
What you'll see
The plugin emits two kinds of context fragments:
[temporal-core] session elapsed: 12m 34s— at every user turn, the time since the session began[temporal-core] since last action: 42s— before every tool call, the time since the most recent prior action (user prompt or previous tool). Suppressed when under 5s to reduce noise.
These are not commands. They are signals — like a wristwatch glance. Notice them; let them shape your reasoning.
How to use them
Pacing decisions
If you've been working on a task for a long time (session elapsed: 1h 12m) and you're still scoping rather than executing, that's a signal to commit. Conversely, if elapsed is small and the user's request is large, it's fine to take time to think.
Deadline-aware prioritization
When the user mentions a deadline ("I need this in 30 minutes", "before EOD"), record it and check it against session elapsed at each turn. If you're 25 minutes into a 30-minute task, switch from exploration to delivery.
Recency reasoning
When the user references prior work ("the bug we fixed earlier", "what you did just now"), session elapsed tells you the temporal distance. Earlier-in-session is recent; don't conflate it with earlier-in-history-from-training.
Operation-pacing awareness
since last action lets you sense whether you're in fast-iteration mode (consecutive small gaps) or deliberation mode (multi-minute gaps). Use this to calibrate: was that long pause warranted?
Honest reporting
When the user asks "how long did this take?", the elapsed signals give you an answer based on actual time, not a guess.
When the signals are absent
If you don't see [temporal-core] fragments in this turn or recent turns, the plugin isn't installed or the hooks didn't fire. In that case, fall back to the system clock (date via Bash) when you genuinely need time information. Don't fabricate elapsed times.
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.

temporal-awareness is a skill published in the GitHub repository Evanyuan-builder/temporal-core (0 stars, last pushed 3mo ago), licensed Apache-2.0. It adds 95 tokens to every session and 757 once invoked, about $0.0005 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.
