khal

A command-line workflow for reading calendar events with khal, a terminal calendar program. It can list events for dates or ranges and filter the displayed title, description, or location after retrieving them.

In plain words
What is it for?
Use it to find today’s events, upcoming meetings, events across a custom date range, or matching calendar entries by collecting a wider range and filtering the results.
Why use it?
It helps answer schedule questions from the terminal even though khal has no built-in full-text search command.

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

khal 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 yesterday.

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

Khal

Read calendar events from the terminal with khal.

khal list --format '{calendar}|{start}|{end}|{title}|{location}|{description}|{status}' today eod

List Events

Today's events:

khal list --format '{calendar}|{start}|{end}|{title}|{location}|{description}|{status}' today eod

Next 7 days:

khal list --format '{calendar}|{start}|{end}|{title}|{location}|{description}|{status}' today 7d

Custom range:

khal list --format '{calendar}|{start}|{end}|{title}|{location}|{description}|{status}' "start-date" "end-date"

Common date examples: now, today, tomorrow, eod, 7d, 2026-02-21.

Search Events

khal does not provide a native full-text search command.

Use a wide date range and filter results in your response:

khal list --format '{calendar}|{start}|{end}|{title}|{location}|{description}|{status}' today 365d

Filter by keyword in title, description, or location after collecting the output.

Parsing Notes

  • Event rows use | separators in the format above
  • khal may print date header lines (for example Monday, 2026-02-23); treat those as section headers, not events
  • Return at most the number of events requested by the user
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.
