What is glean-tool-selection?

A set of always-active rules for choosing the right Glean search tool for different questions. Glean is a company search system that can search sources such as documents, email, meetings, and code.

Use it to route document, email, meeting, code, activity, people, and multi-source questions, and to ensure results include links for verification.

It prevents people and questions from being sent to the wrong search method, which can produce incomplete or misleading results.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00288	$0.00288
Opus 5.5	$0.00115	$0.00115

Security

Grade A, and why

glean-tool-selection 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 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.

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.
