Bug Description

Kiro IDE Agent Chat does not correctly render inline LaTeX mathematical expressions delimited by $...$, even though display equations delimited by $$...$$ render successfully.

I also tested alternative LaTeX delimiters (\(...\) and \[...\]), but neither rendered correctly in Agent Chat.

Enabling "chat.math.enabled": true in the IDE's settings.json does not resolve the issue.

This appears to be a limitation or defect in the Agent Chat Markdown/math rendering pipeline, rather than a general inability to render mathematical expressions.

Related issue: #9880

The previous issue was closed during backlog cleanup on August 21, 2026. The maintainer explicitly invited users to file a new report with their current Kiro version and a fresh Conversation ID if the problem persisted.

Environment

• Product: Kiro IDE

• Kiro version: 1.4.26

• Operating system: macOS 26.4

• Interface: Agent Chat

• Relevant user setting: "chat.math.enabled": true

Thank you for investigating this issue.

Steps to Reproduce

Steps to Reproduce

1. Open Kiro IDE and start a fresh Agent Chat conversation.

2. Send the following prompt:

   Please output the following mathematical expressions exactly as ordinary Markdown, without code fences. Do not escape or modify any LaTeX delimiters.

   Inline dollar syntax: $x^2 + y^2 = z^2$

   Inline parenthesis syntax: \(x^2 + y^2 = z^2\)

   Display dollar syntax:

   $$x^2 + y^2 = z^2$$

   Display bracket syntax: \[x^2 + y^2 = z^2\]

3. Inspect the rendered assistant response in the Agent Chat panel.

4. Open the IDE user settings and configure "chat.math.enabled": true.

5. Reload the IDE window and repeat the test in a new conversation.

Expected Behavior

Expected Behavior

Kiro Agent Chat should correctly render inline LaTeX math delimited by $...$ within ordinary Markdown prose.

For example, the following sentence:

The loss is $L(\theta)$, and the gradient is $\nabla_\theta L(\theta)$.

should render both mathematical expressions inline without displaying their literal LaTeX delimiters.

Both inline and display mathematical expressions should be supported:

• Inline math: $...$

• Display math: $$...$$

Inline expressions should preserve normal paragraph flow, rather than requiring separate display equation blocks.

Actual Behavior

The observed results are:

Only the $$...$$ display math syntax produces the expected mathematical rendering.

The standard $...$ syntax remains unrendered in normal prose.

Setting "chat.math.enabled": true does not change this behavior.

Additional Context

Additional Context

I have already tried explicitly enabling mathematical rendering with:

{  "chat.fontSize": 14,  "chat.math.enabled": true}

The issue persists.

Since VS Code supports math rendering in its native Chat interface, it would be helpful to clarify whether Kiro Agent Chat uses a separate Markdown rendering pipeline and whether the corresponding inline math capability can be enabled.

Requested resolution:

1. Support standard $...$ inline LaTeX rendering directly in Kiro Agent Chat.

2. Ensure that inline equations render correctly within ordinary prose.

3. Clarify whether chat.math.enabled is intended to apply to Kiro Agent Chat.
