Fixes numman-ali#68 The plugin's request transformer was removing the entire OpenCode system prompt in CODEX mode, which inadvertently dropped custom instructions from AGENTS.md and other instruction files that OpenCode appends to the prompt. Changes: - Add extractCustomInstructions() to parse instruction blocks - Modify filterOpenCodeSystemPrompts() to extract and return custom instructions - Update transformRequestBody() to re-insert custom instructions after bridge message - Add tests to verify custom instruction extraction works correctly The fix extracts blocks starting with 'Instructions from:' before filtering the OpenCode prompt, then re-inserts them as separate developer messages, ensuring they are included in requests to the Codex API.

Summary
Fixes #68 - The plugin was dropping custom instructions from
AGENTS.mdand other instruction files when using CODEX mode.Problem
In CODEX mode, the plugin filters out the entire OpenCode system prompt and replaces it with a Codex-compatible bridge message. However, OpenCode appends custom instruction files (like
AGENTS.md) directly into the system prompt. When the plugin filtered the prompt, it inadvertently dropped all custom instructions.Solution
Implemented the fix proposed in issue #68:
Instructions from:Changes
extractCustomInstructions()function to parse and extract instruction blocksfilterOpenCodeSystemPrompts()to return both filtered input and extracted custom instructionstransformRequestBody()to re-insert custom instructions after the bridge messageTesting
Impact
Users can now use custom instructions from
AGENTS.md, project-wide./AGENTS.md, and other instruction files with CODEX mode without losing their configurations.
