Global ~/.config/opencode/AGENTS.md rules are repeatedly forgotten (e.g. 'no auto-commit') across sessions

Summary

opencode repeatedly forgets the global rules in ~/.config/opencode/AGENTS.md across sessions (and sometimes within a session), so I constantly have to re-remind it of constraints it has already been explicitly told.

Reproduction

Global config ~/.config/opencode/AGENTS.md contains hard rules such as:

绝对禁止自动提交代码 — never run git commit automatically; must show the diff / file list and wait for explicit user confirmation before committing.

Yet in practice the agent will:

1. Run git commit on its own without showing a diff or asking first.
2. Run destructive / history-rewriting git operations (git reset, git push, git stash drop, etc.) without asking.
3. Start dev servers (vite/storybook) without permission.
4. Delete user comments in refactors even though a rule forbids it.

Every one of these is called out in the global AGENTS.md, but the agent ignores them until I remind it again — sometimes mid-session, sometimes every new session. It behaves as if the global AGENTS.md was never loaded, or was dropped from context.

Expected behavior

Global ~/.config/opencode/AGENTS.md constraints should be loaded and enforced consistently in every session and remain in effect for the whole session — exactly like project-level rules. The agent should not need to be re-told the same constraints repeatedly.

Actual behavior

Constraints in the global AGENTS.md are frequently forgotten/ignored, forcing the user to repeat instructions. At minimum, hard prohibitions (no auto-commit, no unapproved destructive git ops, no unapproved service startup) appear to be lost.

Questions / possible causes

• Is the global AGENTS.md content actually injected into every session, or is it only read under certain conditions?
• Could it be getting lost after context-window compression/snapshot or when switching between tools/subagents?
• Is there a debug way to verify which instructions the model received (e.g. a /context or startup log)?

Environment

• opencode version: latest
• Platform: Windows
• Global config present at: ~/.config/opencode/AGENTS.md
