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.

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 | $0.00000 | $0.00759 |
| Opus 5 | $0.00000 | $0.00380 |
| Sonnet 5 | $0.00000 | $0.00152 |
| Haiku 4.5 | $0.00000 | $0.00076 |
Grade A, and why
agent-list 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.
How it starts
The opening of the file, as written. The whole thing — 110 lines — stays where its author put it; the contents beside it link to each section on GitHub.
Agent Lists
Detailed reference for nylas agent list.
Lists are backed by /v3/lists and hold normalized values referenced by agent
rule in_list conditions. Each list has an immutable type — domain, tld,
or address — that determines which rule fields it can match:
| List type | Matches rule fields |
|---|---|
domain |
from.domain, recipient.domain |
tld |
from.tld, recipient.tld |
address |
from.address, recipient.address |

Commands
nylas agent list list

Listing Lists
nylas agent list list
nylas agent list list --json
Lists all lists from /v3/lists with their type and item count.
Showing a List
nylas agent list get <list-id>
nylas agent list get <list-id> --json
nylas agent list items <list-id>
Notes:
getshows the list metadata and its itemsitemsshows only the items--jsonreturns raw payloads
Creating Lists
nylas agent list create --name "Blocked domains" --type domain
nylas agent list create --name "VIPs" --type address --item [email protected]
Notes:
--typeis required and immutable after creation (domain,tld, oraddress)--itemis repeatable and seeds the list right after creation--descriptionis optional
Managing Items
nylas agent list add <list-id> spam.com junk.net
nylas agent list remove <list-id> spam.com
Notes:
- up to 1000 items per request
- values are lowercased, trimmed, and validated against the list's type by the API
- duplicate additions are silently ignored
- rules referencing the list pick up item changes immediately
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.

agent-list is a command published in the GitHub repository nylas/cli (68 stars, last pushed 13d ago), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 759 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-30.
