Deadline Calculator

Deadline computation for limitation periods, response windows, contract expiry and probation end. Uses the Civil Code convention by default (the starting day is excluded; counting begins the next day). When the expiry date lands on a statutory holiday or weekly rest day it rolls forward automatically and lists each skipped day for review. Working-day counting requires the current year holiday schedule to be filled in first.

How to install

Skill packages follow the open Agent Skills standard (one directory plus a SKILL.md). No request or licence is needed. Pick whichever path matches your client, then just describe the task in chat to trigger it.

① Import the package

Recommended

Download the skill zip and load it from your client's "import / upload local skill package" entry. If SKILL.md sits at the top level of the archive, the package is well formed.

② Command line

For command-line clients that support the Agent Skills standard: one command syncs the skill into your local skills directory.

$npx skills add m9ai/m9ai-skills --skill deadline-calculator-skill

Pass -a to name the client (claude-code, codex); omit it and you will be asked which one to use.

③ Unzip manually

You can also unzip the archive straight into your client's skills directory - no installer to run. The zip is self-contained and can be distributed offline, which makes it easy to host on an internal file server for company-wide rollout.

WorkBuddySettings → Skills directory (as shown in the client)

Claude Code (user level)~/.claude/skills/

Claude Code (project level).claude/skills/

Other clients supporting the Agent Skills standard work the same way: drop the skill directory into their skills folder.

Ready-made skills cover generic scenarios. Internal data sources, private models and compliance requirements call for a tailored build.
