When an AI coding answer misses the mark, the instinct is to paste more code. Usually that makes it worse. The model needs the right context, not all of it<\/strong>, and a short brief beats a 3,000-line dump almost every time. You will find this brief built into most prompts in the code library<\/a>.<\/p>\n\n\n\n

Here is how we write a reusable context brief<\/strong>: a few paragraphs about the project that go at the top of every coding prompt. It is the same idea as the reusable persona<\/a>, just for your codebase.<\/p>\n\n\n\n

Why the full dump fails<\/h2>\n\n\n\n
    \n
  • Important details get lost among unrelated files.<\/li>\n\n\n\n
  • The model starts copying patterns from old or deprecated code.<\/li>\n\n\n\n
  • You hit length limits and the most relevant part gets cut.<\/li>\n<\/ul>\n\n\n\n

    What goes into a context brief<\/h2>\n\n\n\n

    Keep it to what a new developer would need on day one:<\/p>\n\n\n\n

    Project: WordPress plugin, PHP 8.0+, no Composer dependencies.\nCoding standard: WordPress Coding Standards, tabs for indentation.\nArchitecture: one class per file in \/includes, prefixed APM_.\nData: custom post types and taxonomies, no custom tables except\na usage log.\nRules:\n- Escape all output (esc_html, esc_attr, esc_url).\n- Every REST route has a permission_callback.\n- No jQuery in new front-end code.<\/code><\/pre>\n\n\n\n
    Add a map, not the territory<\/h3>\n\n\n\n
    A short file tree tells the model where things live without showing every line:<\/p>\n\n\n\n
    includes\/\n  class-apm-assembler.php   builds the final prompt\n  class-apm-rest.php        REST routes (apm\/v1)\n  class-apm-fields.php      meta registration + sanitizers\ntemplates\/\n  card.php, single-prompt.php<\/pre>\n\n\n\n
    Interfaces, not implementations<\/h3>\n\n\n\n
    When the task touches another part of the code, include the function signatures and docblocks, not the full bodies. That’s usually enough for the model to call them correctly:<\/p>\n\n\n\n
    \/**\n * Assemble a prompt with snippets, variables and kind details.\n *\n * @return array{text:string,missing:string[]}|WP_Error\n *\/\npublic static function assemble( int $prompt_id, array $args = array() );<\/code><\/pre>\n\n\n\n
    Make it a habit<\/h2>\n\n\n\n
      \n
    1. Write the brief once and store it as a reusable snippet.<\/li>\n\n\n\n
    2. Include it at the top of every coding prompt for that project.<\/li>\n\n\n\n
    3. Paste only the file you are changing, plus signatures of anything it calls.<\/li>\n\n\n\n
    4. Update the brief when a convention changes, not when a prompt fails.<\/li>\n<\/ol>\n\n\n\n
      \n
      Context is a budget. Spend it on what the model can’t guess.<\/p>\nFrom our internal prompt guidelines<\/cite><\/blockquote>\n","protected":false},"excerpt":{"rendered":"
