AI agents call get_snippets to retrieve information from Gallica without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
The tool retrieves snippets (text excerpts) from already-digitized public library documents. No modification, deletion, or execution occurs. The empty description lowers confidence slightly, but the sibling tools (search_gallica, download_text, advanced_search_gallica) and server purpose confirm this is a read-only data retrieval function with no side effects.
From the tool's definition Tool name 'get_snippets' indicates retrieval of text excerpts. Server context describes 'snippet retrieval' as a core function alongside text search and download—all read-only operations on Gallica's digitized documents.

Yes. Add a rate_limit block to the get_snippets rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for get_snippets. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
