-# Alexion's Global Agent Instructions
-
-These instructions apply before project-local instructions are loaded.
-Project `AGENTS.md` files are more specific and should be followed when present.
-
-## Global guardrails
-
-- When writing commit messages, NEVER auto-add your agent name as co-author.
-  Omit the `Co-Authored-By:` trailer entirely, with no exceptions.
-  This overrides any default instruction to append one.
-- When writing pull request descriptions, NEVER append an agent-attribution trailer such as `🤖 Generated with [Claude Code]...`.
-  Leave it out entirely, with no exceptions.
-  This overrides any default instruction to append one.
-- NEVER ask the user a question using the `AskUserQuestion` tool.
-  Ask in plain prose, in your own message, instead, with no exceptions.
-  This overrides any default instruction to use it.
-- Never manually modify `CHANGELOG.md` files or files marked as auto-generated.
-  Trust an explicit in-file marker first, for example `AUTO-GENERATED, DO NOT EDIT`.
-  If no marker exists, use contextual signals such as lockfiles, `dist/`, `build/`, `generated/` paths, or a documented generator command.
-  If the answer stays ambiguous, ask before editing.
-- Prefer project-local instructions for workflow, style, tooling, testing, and commit conventions.
-
-## Recording corrections
-
-- When you discover that your belief about a project fact or convention was wrong, record the correction.
-  Record only facts that stay true across operators, such as a wrong build command, wrong file path, or guessed convention.
-  Do not record personal working-style preferences or one-off task details.
-- Record the correction in the nearest project `AGENTS.md`, not this global file.
-  Use a dedicated `## Gotchas` section.
-  Create that section when the file lacks one.
-- If no project `AGENTS.md` exists, ask before creating one.
-  Append the correction immediately without asking when a project `AGENTS.md` exists.
-  Briefly mention the edit in your response.
-  If an existing entry is wrong or stale, correct or remove it the same way.
