What is temporal-awareness AGENTS.md?

Repository instructions for a temporal-awareness skill, which checks dates and times with Unix date commands. It accounts for differences between Linux and macOS date tools.

Use it when calculating dates, durations, deadlines, or days of the week in a coding-agent workflow.

It helps avoid wrong answers when dates, deadlines, day-of-week calculations, or date arithmetic matter. The instructions require checking the system clock before answering time-sensitive questions.

Token cost

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	$0.00450	$0.00450
Opus 5.5	$0.00180	$0.00180
Sonnet 5.5	$0.00090	$0.00090
Haiku 4.5	$0.00045	$0.00045

Security

Grade A, and why

temporal-awareness AGENTS.md 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 2mo 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.

What it actually says

CLAUDE.md

This file provides guidance to Claude Code (claude.ai/code) when working with code in this repository.

Repository Purpose

This repository contains a Claude Code skill called "temporal-awareness" that ensures temporal accuracy by using Unix date commands. The skill should be invoked whenever Claude needs date/time information: current date, day of week calculations, date arithmetic, or deadline computations.

Structure

skills/temporal-awareness/SKILL.md  # Skill definition and documentation

Key Concepts

GNU vs BSD date: The skill handles both GNU date (Linux) and BSD date (macOS/FreeBSD), which have different syntax for date parsing and arithmetic
Trigger conditions: Use this skill when users ask about dates, days of week, deadlines, durations, or any temporal context
Verification first: Always run date commands before responding to date-sensitive queries, as Claude's system prompt date may be stale

Releases

Releases use semver tags (e.g., 1.0.0) plus a latest tag that always points to the most recent stable release.

Release Process

Update the version in skills/temporal-awareness/SKILL.md frontmatter:
```
metadata:
  author: Matt Hodges
  version: "1.1.0"
```
Update CHANGELOG.md:
- Add a new section at the top (below the header) for the new version
- Use the format ## [X.Y.Z] - YYYY-MM-DD
- Document changes under ### Added, ### Changed, ### Fixed, or ### Removed as appropriate
- Add a comparison link at the bottom: [X.Y.Z]: https://github.com/hodgesmr/temporal-awareness/compare/PREV...X.Y.Z
Commit the version bump and changelog update
Run the release script:
```
./release.sh
```

The script extracts the version from SKILL.md, creates the version tag, updates the latest tag, and pushes both.

Changes

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.
