Comments suppressed due to low confidence (4)

agents/voidbeast-gpt41enhanced.agent.md:1

• This agent is still listed in docs/README.agents.md (see row around line 221), including install links that point to ../agents/voidbeast-gpt41enhanced.agent.md. Since this file is being removed, the docs will contain broken links; please remove that entry (or regenerate the agents README via npm start) as part of this PR.
  agents/rust-gpt-4.1-beast-mode.agent.md:1
• This agent is still listed in docs/README.agents.md (row around line 180) with install links to ../agents/rust-gpt-4.1-beast-mode.agent.md. After deleting this file, that documentation will be a dead link; please remove/update the docs entry (ideally by running npm start and committing the generated README changes).
  agents/gpt-5-beast-mode.agent.md:1
• docs/README.agents.md still references this agent (row around line 106) and includes install links to ../agents/gpt-5-beast-mode.agent.md. Since the agent file is being removed, please remove/update that docs entry (regenerate via npm start) to avoid broken links.
  agents/4.1-Beast.agent.md:1
• docs/README.agents.md still lists this agent (row around line 28) and links to ../agents/4.1-Beast.agent.md. Deleting the agent file will leave broken links in the agents README; please remove/update that entry (typically by running npm start so generated docs stay in sync).

Thanks for helping clean up some of our older items.

While it's true that they may still have aspects that influence agents, much of the behaviours that they address are changes already expected within the current generation of models.
