When injecting system instructions into the chat prompt, include: 1. **Operating system** and **working directory** from the `workspace_agents` table 2. **Home-level instructions** from `~/.coder/AGENTS.md` (existing behavior) 3. **Project-level instructions** from `<pwd>/AGENTS.md` (new) The XML tag is renamed from `<coder-home-instructions>` to `<system-instructions>` since it now carries more than just the home instruction file. ### Example output (both files present) ```xml <system-instructions> Operating System: linux Working Directory: /home/coder/coder Source: /home/coder/.coder/AGENTS.md ... home instructions ... Source: /home/coder/coder/AGENTS.md ... project instructions ... </system-instructions> ``` ### Example output (no AGENTS.md files) ```xml <system-instructions> Operating System: linux Working Directory: /home/coder/coder </system-instructions> ``` ### Changes - **`coderd/chatd/instruction.go`**: - Renamed types: `homeInstructionContext` → `agentContext`, added `instructionFile` struct - Extracted `readInstructionFileAtPath` shared helper - Added `readWorkingDirectoryInstructionFile` to read `<pwd>/AGENTS.md` - Replaced `formatHomeInstruction` with `formatInstructions` that renders both files under `<system-instructions>` - **`coderd/chatd/chatd.go`**: - Renamed `resolveHomeInstruction` → `resolveInstructions`; now reads both home and pwd instruction files - `resolveAgentContext` returns `agentContext` (renamed from `homeInstructionContext`) - pwd file read is skipped gracefully if directory is empty or file doesn't exist - **`coderd/chatd/instruction_test.go`**: - Added `TestReadWorkingDirectoryInstructionFile` (success, not-found, empty-directory) - Replaced `TestFormatHomeInstruction` with `TestFormatInstructions` covering all combinations - Added ordering test (`AgentContextBeforeFiles`) to verify OS/pwd appear before file sources
