{"repo":"NousResearch/hermes-agent","public_id":"103599","display_label":"Repetition guard extended to tool-call arguments","summary":"These issues and pull requests address a gap where the agent's repetition guard was not applied to tool-call arguments, allowing degenerate or looping model output to be executed as commands. The work covers detection, rejection, and related guard resets on human speech.","subsystem":null,"counts":{"members":6,"open_issues":0,"open_issues_distinct":0,"open_prs":0,"closed_issues":1,"merged_prs":1,"attempt_prs":4},"landed_fix":{"status":"merged_to_main","basis":"structural","pr":121600},"resolution":{"state":"resolved","by":"pr-121600"},"freshness":{"state":"verified","last_verified_at":"2026-09-24T17:02:07+00:00","is_stale":false},"grouping":{"backbone":"STRUCTURAL_SPANNING","link_density":0.3333333333333333},"fix_edges":[{"issue_number":100716,"pr_number":121600,"tier":"verified","basis":"closing_ref","confidence":0.95,"recoverable_from_timeline":true},{"issue_number":103599,"pr_number":121600,"tier":"verified","basis":"closing_ref","confidence":0.95,"recoverable_from_timeline":true}],"members":[{"kind":"issue","number":103599,"title":"Repetition guard not applied to tool-call arguments (degenerate model output executed as a command)","url":null,"state":"closed"},{"kind":"pr","number":103612,"title":"fix(agent): reject repetitive arguments from dropped tool streams","url":null,"state":"closed","close_reason":{"refs":[{"kind":"commit","value":"9e2444e763","number":0},{"kind":"pr","value":"#121600","number":121600},{"kind":"pr","value":"#103599","number":103599}],"category":"merged_via","implication":"superseded"},"merged":false},{"kind":"pr","number":103615,"title":"fix(agent): apply repetition guard to tool-call arguments to abort degenerate commands (#103599)","url":null,"state":"closed","close_reason":{"refs":[{"kind":"commit","value":"9e2444e763","number":0},{"kind":"pr","value":"#103599","number":103599},{"kind":"pr","value":"#121600","number":121600}],"category":"implemented_elsewhere","implication":"superseded"},"merged":false},{"kind":"pr","number":103620,"title":"fix(agent): apply repetition guard to tool-call arguments (#103599)","url":null,"state":"closed","close_reason":{"refs":[{"kind":"commit","value":"9e2444e763","number":0},{"kind":"pr","value":"#103599","number":103599},{"kind":"pr","value":"#121600","number":121600}],"category":"implemented_elsewhere","implication":"superseded"},"merged":false},{"kind":"pr","number":114504,"title":"fix(gateway,agent): reset bot-loop guard on human speech; flag repetition-dominated tool args","url":null,"state":"closed","close_reason":{"refs":[{"kind":"pr","value":"#121600","number":121600}],"category":"superseded_by_pr","implication":"superseded"},"merged":false},{"kind":"pr","number":121600,"title":"fix(agent): repetition guard catches real loops on every completion path; reject degenerate dropped-stream tool args","url":null,"state":"merged","close_reason":{"category":"merged","implication":"superseded"},"merged":true,"is_fix_pr":true,"fix_tier":"verified","files_changed":["agent/chat_completion_helpers.py","agent/repetition_guard.py","agent/turn_final_response.py","agent/turn_truncation.py","tests/agent/test_continuation_repetition_guard.py","tests/agent/test_repeated_dropped_tool_args.py","tests/agent/test_repetition_guard.py"]}],"trust":{"default_tier":"verified","includes_suggested":false}}
