Vellum Assistant is a personal AI assistant that remembers information about users, learns their preferences, and takes actions across connected apps. It is intended for people who want an assistant that can manage conversations, unfinished work, and proactive notifications over time. The catalogue skills, hooks, instruction, and setting configure or extend how the assistant works.
Getting it into your agent
One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

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 | $0.00021 | $0.03372 |
| Opus 5.5 | $0.00008 | $0.01349 |
| Sonnet 5.5 | $0.00004 | $0.00674 |
| Haiku 4.5 | $0.00002 | $0.00337 |
Grade A, and why
outlook scanned grade A with 1 finding 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 1mo 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.
Makes network callslowCapability
Not a fault in itself. Listed so you know the mod talks to something, and to what.
3. **Never try alternative approaches.** Don't use curl, browser automation, or any workaround. If the scripts can't do it, the reconnection flow is the answer. How it starts
The opening of the file, as written. The whole thing — 228 lines — stays where its author put it; the contents beside it link to each section on GitHub.
This skill provides Outlook-specific operations beyond the shared messaging skill. For cross-platform messaging (send, read, search, reply), use the messaging skill. Outlook operations depend on the messaging skill's provider infrastructure - load messaging first if Outlook is not yet connected.
Script Reference
All operations use CLI scripts that return JSON:
- Success:
{ "ok": true, "data": ... } - Failure:
{ "ok": false, "error": "..." }

What ships with it
6 files beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.
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.
