What happened

The WebSearch tool is advertised to the model in the tool list every turn even when it cannot possibly run. Availability is only checked inside the tool's impl/search() — i.e. at call time — so the model spends a turn (and tokens) calling a tool that is guaranteed to fail:

  • Desktop path: apps/desktop/src/main/tool-assembly.ts builds buildWebSearchAgentTool() unconditionally into builtinTools; the settings/credential/privacy checks in apps/desktop/src/main/web-search/agent-tool.ts all live in impl, returning web_search_error { reason: not_configured | incognito_active }.
  • Host path: packages/runtime-host/src/server/web-search-tool.ts has the same shape — resolveWebSearchExecution() is only consulted inside search().

The Settings · Web search toggle (webSearch.enabled, which defaults to false), the Tavily credential status, and privacy/incognito mode have zero effect on the model-visible surface. This contradicts the tool's own fail-closed documentation ("Fail-closed paths" in agent-tool.ts) and its description, which actively invites calls ("Use ONLY when the user asks for current external information").

How to reproduce

  1. Leave web search disabled (the default), or unset the Tavily key, or enable privacy mode.
  2. Start a session with a real backend.
  3. Ask something that could benefit from current external information.
  4. Expected: the model never sees WebSearch in its tool list (or the surface marks it unavailable), so it never attempts it.
  5. Actual: WebSearch is in the tool list every turn; the model calls it and gets a web_search_error back, wasting a turn. In deep-research sessions WebSearch is also in DEEP_RESEARCH_ALLOWED_TOOL_NAMES (desktop-backend-tool-surface.ts), so a disabled web search silently cripples the DR toolset too.

Suggested direction

The availability logic already exists and returns rich states: resolveWebSearchExecution() in packages/storage/src/runtime-policy/coordinator.ts:535 yields privacy_mode | disabled | credential_not_configured | ready. It is simply only consulted at call time. Options:

  • Filter WebSearch out of the effective tool surface (tool-assembly.ts / desktop-backend-tool-surface.ts, and the host's execution-model-composition.ts) based on the same check, recomputed per turn so mid-session toggle changes take effect.
  • Alternatively, keep the tool but attach availability metadata to the surface so the model knows not to call it — though hiding is closer to the existing fail-closed posture and to how capability-gated tools are handled.

Also worth deciding: Settings · Web search wording should state when the tool is hidden from the model vs. merely failing at call time.

Environment

  • Surface: Desktop (Runtime Host shares the same pattern)
  • Commit: current main

Logs, screenshots, or additional context

  • apps/desktop/src/main/tool-assembly.ts — webSearchTool added to toolsAfterSkill / builtinTools unconditionally
  • apps/desktop/src/main/web-search/agent-tool.ts — fail-closed checks only inside impl
  • packages/runtime-host/src/server/web-search-tool.ts — resolveWebSearchExecution() only inside search()
  • packages/storage/src/runtime-policy/coordinator.ts — resolveWebSearchExecution(), the existing availability seam

                  • Desktop path: apps/desktop/src/main/tool-assembly.ts builds buildWebSearchAgentTool() unconditionally into builtinTools; the settings/credential/privacy checks in apps/desktop/src/main/web-search/agent-tool.ts all live in impl, returning web_search_error { reason: not_configured | incognito_active }.
                  • Host path: packages/runtime-host/src/server/web-search-tool.ts has the same shape — resolveWebSearchExecution() is only consulted inside search().
                  The Settings · Web search toggle (webSearch.enabled, which defaults to false), the Tavily credential status, and privacy/incognito mode have zero effect on the model-visible surface. This contradicts the tool's own fail-closed documentation ("Fail-closed paths" in agent-tool.ts) and its description, which actively invites calls ("Use ONLY when the user asks for current external information").
                  How to reproduce
                  1. Leave web search disabled (the default), or unset the Tavily key, or enable privacy mode.
                  2. Start a session with a real backend.
                  3. Ask something that could benefit from current external information.
                  4. Expected: the model never sees WebSearch in its tool list (or the surface marks it unavailable), so it never attempts it.
                  5. Actual: WebSearch is in the tool list every turn; the model calls it and gets a web_search_error back, wasting a turn. In deep-research sessions WebSearch is also in DEEP_RESEARCH_ALLOWED_TOOL_NAMES (desktop-backend-tool-surface.ts), so a disabled web search silently cripples the DR toolset too.
                  Suggested direction
                  The availability logic already exists and returns rich states: resolveWebSearchExecution() in packages/storage/src/runtime-policy/coordinator.ts:535 yields privacy_mode | disabled | credential_not_configured | ready. It is simply only consulted at call time. Options:
                  • Filter WebSearch out of the effective tool surface (tool-assembly.ts / desktop-backend-tool-surface.ts, and the host's execution-model-composition.ts) based on the same check, recomputed per turn so mid-session toggle changes take effect.
                  • Alternatively, keep the tool but attach availability metadata to the surface so the model knows not to call it — though hiding is closer to the existing fail-closed posture and to how capability-gated tools are handled.
                  Also worth deciding: Settings · Web search wording should state when the tool is hidden from the model vs. merely failing at call time.

                              What happened
                              The WebSearch tool is advertised to the model in the tool list every turn even when it cannot possibly run. Availability is only checked inside the tool's impl/search() — i.e. at call time — so the model spends a turn (and tokens) calling a tool that is guaranteed to fail:
                              • Desktop path: apps/desktop/src/main/tool-assembly.ts builds buildWebSearchAgentTool() unconditionally into builtinTools; the settings/credential/privacy checks in apps/desktop/src/main/web-search/agent-tool.ts all live in impl, returning web_search_error { reason: not_configured | incognito_active }.
                              • Host path: packages/runtime-host/src/server/web-search-tool.ts has the same shape — resolveWebSearchExecution() is only consulted inside search().
                              The Settings · Web search toggle (webSearch.enabled, which defaults to false), the Tavily credential status, and privacy/incognito mode have zero effect on the model-visible surface. This contradicts the tool's own fail-closed documentation ("Fail-closed paths" in agent-tool.ts) and its description, which actively invites calls ("Use ONLY when the user asks for current external information").
                              How to reproduce
                              1. Leave web search disabled (the default), or unset the Tavily key, or enable privacy mode.
                              2. Start a session with a real backend.
                              3. Ask something that could benefit from current external information.
                              4. Expected: the model never sees WebSearch in its tool list (or the surface marks it unavailable), so it never attempts it.
                              5. Actual: WebSearch is in the tool list every turn; the model calls it and gets a web_search_error back, wasting a turn. In deep-research sessions WebSearch is also in DEEP_RESEARCH_ALLOWED_TOOL_NAMES (desktop-backend-tool-surface.ts), so a disabled web search silently cripples the DR toolset too.
                              Suggested direction
                              The availability logic already exists and returns rich states: resolveWebSearchExecution() in packages/storage/src/runtime-policy/coordinator.ts:535 yields privacy_mode | disabled | credential_not_configured | ready. It is simply only consulted at call time. Options:
                              • Filter WebSearch out of the effective tool surface (tool-assembly.ts / desktop-backend-tool-surface.ts, and the host's execution-model-composition.ts) based on the same check, recomputed per turn so mid-session toggle changes take effect.
                              • Alternatively, keep the tool but attach availability metadata to the surface so the model knows not to call it — though hiding is closer to the existing fail-closed posture and to how capability-gated tools are handled.
                              Also worth deciding: Settings · Web search wording should state when the tool is hidden from the model vs. merely failing at call time.
                              Environment
                              • Surface: Desktop (Runtime Host shares the same pattern)
                              • Commit: current main
                              Logs, screenshots, or additional context
                              • apps/desktop/src/main/tool-assembly.ts — webSearchTool added to toolsAfterSkill / builtinTools unconditionally
                              • apps/desktop/src/main/web-search/agent-tool.ts — fail-closed checks only inside impl
                              • packages/runtime-host/src/server/web-search-tool.ts — resolveWebSearchExecution() only inside search()
                              • packages/storage/src/runtime-policy/coordinator.ts — resolveWebSearchExecution(), the existing availability seam
