| ## What are skills? | ||
|
|
||
| Skills are modular extensions that provide: | ||
|
|
||
| - Specialized knowledge: Domain-specific expertise (e.g., PDF processing, data analysis) | ||
| - Workflow patterns: Best practices for common tasks | ||
| - Tool integrations: Pre-configured tool chains for specific operations | ||
| - Reference material: Documentation, templates, and examples | ||
|
|
||
| ## How to use skills | ||
|
|
||
| Identify the skills that are likely to be useful for the tasks you are currently working on, use the `skill` tool to load a skill for detailed instructions, guidelines, scripts and more. |

I think this is redundant
There is a later section of system prompt that mentions skills.
But ill merge as is but just letting u know, if u have follow up changes u want I can merge those too.

Good catch. I will remove the dedicated # Skills section from the Kimi prompt so we don’t restate skill behavior in two places.

Issue for this PR
Closes #20258
Type of change
What does this PR do?
This PR introduces a dedicated system prompt for Kimi models and updates prompt selection so that model IDs containing
kimiuse this prompt instead of the generic default prompt.We are submitting this on behalf of Moonshot AI. The prompt content added here is migrated from Kimi Code CLI, where it is specifically tuned for Kimi-series models. The objective is to preserve the prompting style that is already known to work well for these models, while keeping the implementation isolated and low-risk.
Importantly, this prompt has been tested internally and is able to recover the performance regression observed on our internal benchmarks when Kimi models are run with the generic default prompt.
Scope of the change:
packages/opencode/src/session/prompt/kimi.txtpackages/opencode/src/session/system.tssokimimodel IDs resolve to the Kimi-specific promptHow did you verify your code works?
