Summary

When [agent.tool_filter] is enabled, the /status command does not show whether dynamic tool schema filtering is active, nor the current filter configuration (top_k, always_on count).

Observed behavior (v0.16.0)

/status
Session status:
Provider:  openai
Model:     gpt-4o-mini
...

No mention of tool filter state.

Expected behavior

When [agent.tool_filter] enabled = true, status should show something like:

Tool filter: enabled (top_k=6, always_on=6, 11 embeddings)

Or at minimum a line like Tool filter: active.

Context

• Found during CI session 2026-03-20 testing PR research(tools): dynamic tool schema filtering to reduce context waste and improve selection accuracy #2020 dynamic tool schema filtering.
• The filter itself works correctly — this is a UX observability gap only.
• Low priority: tool filter is opt-in and disabled by default.

Acceptance criteria

• /status output includes a tool filter line when tool_filter.enabled = true
• Shows top_k, always_on count, and number of pre-computed embeddings
• No change when tool filter is disabled (don't add noise for default config)
