searchDocs

Search Extentos conceptual docs by topic or keyword to understand how SDK primitives compose into real flows and how features are meant to be used.

Instructions

Search Extentos documentation by topic or keyword. The conceptual / narrative layer that complements the action-oriented tools — read these to understand how the SDK is meant to be used, not just what calls exist. Canonical post-pivot topics: getting_started (full topic index — read first), custom_handlers (the central composition doc — how to write a Handler class that subscribes to capability primitives), assistant_runtime (the canonical voice-assistant surface; read first if you're building a voice assistant), voice_integration (lower-level primitives — glasses.voice.onPhrase + audio.recordDiscrete + customer-side LLM; for fine-grained control), connection_ui_placement, host_app_scaffold, auto_bind_session_lifecycle, local_bridge_discovery, device_code_flow, connection_state_model, permissions, production_checklist, concurrency_modes, multi_platform_projects, library_api, toggles, audio_video_coexistence, simulator_browser_mode, simulator_session_lifecycle (mint once, reuse, delete deliberately — read before minting a second sim for a project), event_log_schema, file_actions, agent_e2e_testing (how an AI coding agent verifies its own generated handler end-to-end — sim event log + adb-mediated emulator DB read + screencap, the dual-layer pattern that closes the agent loop without a human). Topic IDs are stable. At least one of topic or query is required (enforced by the handler — calling with neither returns an invalid_arguments error). Pass topic alone to fetch the full topic content (most common); pass query alone for keyword search across all topics; pass both to narrow keyword search inside a topic. mode: "snippets" returns only the matching paragraphs instead of full topic bodies — pair with a query when keyword-searching across topics so a single search doesn't dump ~20KB of unrelated content into context. USE to learn how primitives compose into a real flow, or to read up on a specific feature (permissions, toggles, connection lifecycle). DON'T USE for the platform capability list (use getPlatformInfo), call-shape per feature (use getCapabilityGuide), or project-installed state (use inspectIntegration).

Input Schema

TableJSON Schema
NameRequiredDescriptionDefault
modeNoResponse shape. 'full' (default) returns each matching topic's full body — the original behavior, best for reading a single named topic. 'snippets' returns only the paragraphs containing the query terms (up to 3 per topic, ~600 chars each) — best when querying across topics so you don't pay for unrelated content in the agent's context window. Snippets mode requires a query; pure topic fetches always return full content.
queryNoOptional keyword(s). When omitted, the response is the full content of the topic named in `topic`. When both supplied, query narrows within the topic. At least one of `query` or `topic` must be supplied.
topicNoOptional topic id. Omit and pass `query` for cross-topic keyword search; pass topic alone to fetch the topic's full content (most common usage). At least one of `query` or `topic` must be supplied.
Behavior5/5

Does the description disclose side effects, auth requirements, rate limits, or destructive behavior?

With no annotations, the description carries full burden and meets it: it discloses the enforcement rule ('At least one of `topic` or `query` is required... returns an invalid_arguments error'), stable topic IDs, snippets-mode paragraph limits, and the differing behavior when both parameters are supplied.

Agents need to know what a tool does to the world before calling it. Descriptions should go beyond structured annotations to explain consequences.

Conciseness5/5

Is the description appropriately sized, front-loaded, and free of redundancy?

The description is long but densely packed, with each section earning its place: purpose, topic list, usage conditions, mode semantics, and off-path disambiguation. It is front-loaded with the core function, and the extensive topic enumeration prevents invalid calls by providing valid string constants.

Shorter descriptions cost fewer tokens and are easier for agents to parse. Every sentence should earn its place.

Completeness5/5

Given the tool's complexity, does the description cover enough for an agent to succeed on first attempt?

Given no output schema and three mostly optional params, the description covers everything an agent needs: it explains error behavior, mode output shapes, canonical topic IDs, and explicitly contrasts with sibling tools. No critical behavioral aspect is missing.

Complex tools with many parameters or behaviors need more documentation. Simple tools need less. This dimension scales expectations accordingly.

Parameters5/5

Does the description clarify parameter syntax, constraints, interactions, or defaults beyond what the schema provides?

Although the schema already describes each parameter (100% coverage), the description adds essential semantics: the canonical topic list, the three parameter combination patterns (topic alone, query alone, both), and the snippet mode constraint (requires query). This goes far beyond the schema's field-level descriptions.

Input schemas describe structure but not intent. Descriptions should explain non-obvious parameter relationships and valid value ranges.

Purpose5/5

Does the description clearly state what the tool does and how it differs from similar tools?

The description opens with a clear, specific verb+resource: 'Search Extentos documentation by topic or keyword.' It further distinguishes itself from siblings by explicitly naming what it is NOT for ('DON'T USE for the platform capability list (use getPlatformInfo)...'), making its purpose unambiguous.

Agents choose between tools based on descriptions. A clear purpose with a specific verb and resource helps agents select the right tool.

Usage Guidelines5/5

Does the description explain when to use this tool, when not to, or what alternatives exist?

The description provides explicit USE/DON'T USE guidance with named alternates (getPlatformInfo, getCapabilityGuide, inspectIntegration). It also details when to use full vs snippets mode based on query scope, offering context for both common and edge use cases.

Agents often have multiple tools that could apply. Explicit usage guidance like "use X instead of Y when Z" prevents misuse.
