Missing registry.py breaks file editing tools in Scale's SWE-agent fork

[aksakalmustafa]

Issue

The file tools/registry/lib/registry.py appears to be deleted in commit 402a7b8, causing the str_replace_editor tool to fail with: ModuleNotFoundError: No module named 'registry'

Impact

• Primary editing tool is broken - Every str_replace_editor call fails immediately
• Massive retry overhead - Agents waste time retrying
• Degraded patch quality - Agents fall back to unreliable bash commands (sed, echo)
• Wrong outputs - Some models create test files instead of fixing source code

While agents don't completely fail (they use bash fallbacks), editing quality is significantly degraded.

Sample Error From .traj:

"text": "OBSERVATION:\nTraceback (most recent call last):\r\n  File \"/root/tools/edit_anthropic/bin/str_replace_editor\", line 18, in <module>\r\n    from registry import registry as REGISTRY\r\nModuleNotFoundError: No module named 'registry'"

Root Cause

The registry module is a simple key-value store used by multiple tools:

• tools/edit_anthropic/bin/str_replace_editor (line 18)
• tools/diff_state/bin/_state_diff_state (line 9)
• tools/review_on_submit/bin/submit (line 10)
• tools/review_on_submit_m/bin/submit (line 10)
• tools/registry/bin/_read_env (line 5)
• tools/registry/bin/_write_env (line 5)

This file exists in upstream SWE-agent but was deleted during Scale's customizations. The commit message doesn't mention this
deletion, suggesting it was accidental.

Evidence

Upstream has the file:
$ git ls-tree -r 8089c8b tools/registry/lib/ -> 100644 blob registry.py

Scale fork deleted it:
$ git show 402a7b8 | grep registry.py -> tools/registry/lib/registry.py # Deleted in Scale's modifications

Fix

Restore the file from the parent commit:

git show 402a7b8^:tools/registry/lib/registry.py > tools/registry/lib/registry.py
