Expense Claim Audit
A mechanical pre-payment pass over expense claims: required fields present, line items summing to the declared total, duplicate receipt numbers, and suspected splitting (same person, same day, same amount). Over-limit checking needs limits supplied by your organisation via --limit= or --limits-file=; if none are given the check is skipped, since the script ships with no built-in limits. Produces an actionable list of items to send back.

expense-audit-skillHow 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
RecommendedDownload 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.
v1.0.0② 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 expense-audit-skillPass -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.
Settings → Skills directory (as shown in the client)~/.claude/skills/.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.
