Bug Description Title: /insights command: model omits "output exactly" message block, drops report file:// link

Summary: When running /insights, the slash command's prompt ends with an instruction Now output the following message exactly: followed by a <message>...</message> block containing the report file path and a follow-up question. The model (Opus 4.6 1M context) outputs only the trailing question and silently drops the first two lines containing the file:// link to the generated report.

Environment:

• Claude Code v2.1.96
• Model: Opus 4.6 (1M context) — claude-opus-4-6[1m]
• Platform: Windows 11 Pro, bash shell
• No custom /insights override (~/.claude/commands/ empty, no relevant plugins)

Steps to reproduce:

1. Run /insights in a project with enough session history to generate a report.
2. Observe model's text response.

Expected behavior: Model outputs the full <message> block verbatim, including: Your shareable insights report is ready: file://C:\Users\lukak.claude\usage-data\report.html

Want to dig into any section or try one of the suggestions?

Actual behavior: Model outputs only: Want to dig into any section or try one of the suggestions? The file:// link is silently omitted. Reproduced twice in the same session.

Likely root cause: The /insights prompt includes a Here is what the user sees: section that already contains the rendered report with the file:// link near the end. The model appears to classify the second copy in the <message> block as redundant and elides it under output-efficiency heuristics ("don't restate what the user already saw"), overriding the literal output exactly instruction.

Suggested fix (Anthropic side): Either (a) strengthen the /insights prompt wording to make literal compliance non-negotiable (e.g. wrap in a fenced verbatim block, or repeat the "exactly, do not omit any line" constraint immediately before the <message> tag), or (b) tune model behavior so that explicit output exactly / verbatim instructions always defeat output-efficiency heuristics, regardless of perceived redundancy with surrounding context.

Impact: User loses direct access to the generated HTML report path and has to either inspect the rendered insights output manually or ask the model to retrieve it. Breaks a previously-reliable affordance of /insights.
