Tool Namespacing

Conceptual Reference

How to study this: understand why namespacing prevents collisions

Definition

Grouping related tools under common prefixes or suffixes so agents can disambiguate tools and services when many tools are in context.

Agents may face hundreds of tools across multiple MCP servers; namespacing clarifies tool boundaries.
Group related tools under common prefixes/suffixes:
- By service: asana_search, jira_search.
- By resource: asana_projects_search, asana_users_search.
Choice of prefix- vs suffix-based namespacing has non-trivial effects on tool-use evaluations — worth testing.
Names that reflect natural subdivisions of tasks simultaneously reduce the number of tools and tool descriptions loaded into context.

Namespacing is the recommended answer when many tools/servers cause selection ambiguity or context bloat.
Distinguishes service-based vs resource-based grouping conventions.

Prefix vs suffix is not cosmetic — it measurably shifts eval results, so it must be tested rather than assumed.
Namespacing is about disambiguation and context economy, not just aesthetics.

In one sentence, why does this matter for the exam?
