Summary

Removes the useless f prefix from 153 string literals that contain no {expressions} across 3 files. Salvage of #52254 by @AlexFucuson9 (commit authored as @annguyenNous), cherry-picked onto current main with authorship preserved.

Changes

  • gateway/run.py: 68 dead f-prefixes dropped
  • agent/conversation_loop.py: 43 dropped
  • hermes_cli/main.py: 42 dropped

Pure mechanical lint cleanup (ruff F541). No logic touched — each change only removes the f prefix from a static string. Adjacent-string concatenations keep the f on the parts that actually interpolate.

Validation

  • py_compile clean on all 3 files
  • ruff --select F541 reports no remaining hits on the salvaged sites
  • +153 / -153, 3 files only

Closes #52254.

Infographic

removing-dead-f-string-prefixes

Strings with no {expressions} don't need the f-prefix. The f-prefix
adds unnecessary overhead (each f-string is compiled to a format call)
and confuses readers who expect interpolated values.

Fixes 153 occurrences in 3 files:
- gateway/run.py (68)
- agent/conversation_loop.py (43)
- hermes_cli/main.py (42)

Closed — the salvaged change corrupted real code (see analysis on #52254). A correct ruff-derived fix is going up separately.
