From 2c13e2da5e3670d17bd7dcb79f0b020c5b54700e Mon Sep 17 00:00:00 2001 From: Bryan Helmkamp Date: Fri, 24 Jul 2026 17:55:08 -0400 Subject: [PATCH] refactor(agent): load profile system prompts from .md files The three profile prompts lived as multi-line Rust string literals with backslash continuations, which made them awkward to read, diff, and review. Move them to profiles/prompts/*.md loaded via include_str!, matching the existing convention in fabro-workflow's pipeline prompts and the server's playground prompt. Two helpers back the templates, both following the {env_block} convention already used by assemble_system_prompt rather than adding a template engine: - render_prompt substitutes {name} placeholders and leaves the rest intact, for values spliced inline (provider name, the web-search bullet) - splice_optional_section handles whole blocks that come and go, dropping the blank line ahead of the placeholder when the block is empty Gemini already carried a {web_search_section} placeholder in its literal, so that one maps onto render_prompt unchanged. Anthropic's per-section functions collapse into a single template plus a subagent fragment. OpenAI keeps its two one-line file-edit failure hints inline, since they are bound to the tool name and would not read well as standalone files; the multi-line usage blocks they pair with become fragments. Output is unchanged. Verified by capturing all ten prompt variants -- Anthropic across subagent x web-search, OpenAI across apply_patch/edit_file x web-search, Gemini across web-search -- from an unmodified worktree at origin/main, then diffing them byte for byte against this branch.
