Repo context selection

Rank which files are actually relevant to a task before spending context (and tokens) on them.

Coding-agent use case · retrieval & context selectionawesome-jev-by-typesafe

"Repository retrieval and context selection" is a core coding-agent pattern: an agent shouldn't stuff every candidate file into the model's context — it's slow, expensive, and dilutes attention. Instead, score each retrieved file for how relevant it is to the task and keep only the ones that clear a bar. A Jev score is ideal here because it's a compact, calibrated judgment you can threshold and audit, run over many files in parallel for a fraction of a cent each — so the agent reads the three files that matter, not the thirty the retriever returned.

Jev 做出的决策

在一次调用中,Jev 针对同一份输入并行评估以下每一项:

scorerelevance

How relevant is this file to completing the task?

在一个有序量表上给它打分:

  1. irrelevant
  2. loosely related
  3. relevant
  4. central to the fix
noulinclude

Should this file be included in the agent's working context for this task?

返回一个已校准的是/否概率。

noullikely_edit_site

Is this file a likely place the fix will need to be made?

返回一个已校准的是/否概率。

确切的请求

这就是实时演示背后真实的载荷——复制它,改一下 state,你就开始构建了:

{
  "model": "jev-latest",
  "state": "Task: \"Fix the bug where refunds over the order total are silently accepted.\"\n\nCandidate file surfaced by retrieval: `services/billing/refund.py`\n\nSnippet:\n\n  def process_refund(order, amount):\n      # TODO: validate against remaining balance\n      gateway.refund(order.id, amount)\n      record_refund(order, amount)",
  "questions": {
    "relevance": {
      "type": "score",
      "instructions": "How relevant is this file to completing the task?",
      "criteria": [
        "irrelevant",
        "loosely related",
        "relevant",
        "central to the fix"
      ]
    },
    "include": {
      "type": "noul",
      "instructions": "Should this file be included in the agent's working context for this task?"
    },
    "likely_edit_site": {
      "type": "noul",
      "instructions": "Is this file a likely place the fix will need to be made?"
    }
  }
}

把它接进你的代码

读取类型化的答案,用普通代码分支判断——无需解析。自动处理高置信度的情形,把不确定的路由给更大的模型或人工。这只是一次 API 调用,而且输出免费,所以把你需要的每个问题一次都问了吧。
