thisWeek

thisWeek is a skill for Claude Code, Codex from chaitanyagiri/munder-difflin. It costs 77 tokens per session (305 once invoked), scanned A, original, MIT.

A date-range helper for this week so far, from Monday through today. It returns calendar dates and exact UTC times.

In plain words
What is it for?
Use it before reviewing this week’s activity, logs, metrics, or reports.
Why use it?
It prevents errors when calculating week-to-date periods, especially when local dates and UTC times differ. It is read-only and does not use the network.

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.

Security

Grade A, and why

thisWeek 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 4d 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

/thisWeek

Get the concrete date range for this week so far (Monday → today) by running the bundled resolver:

node "$AGENT_DIR/.claude/skills/temporal/when.mjs" thisWeek

It prints a human-readable line plus a JSON record:

  • start / end — inclusive civil dates (YYYY-MM-DD) in your local timezone
  • startUtc / endExclusiveUtc — the same window as a half-open [start, end) range of exact UTC instants, for timestamp-based queries
  • days, timezone, asOf — the span, your timezone, and when this resolved

Use the returned dates as the time bounds for the task at hand. Do not derive dates by hand — this resolver is the source of truth. For the full window list or an arbitrary range (e.g. last45days, last6months), see the /temporal skill.

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.
