From ed20e75254f7f267f3ecc31305309670d903d8c8 Mon Sep 17 00:00:00 2001 From: Edbert Chan Date: Tue, 8 Sep 2026 22:50:37 -0700 Subject: [PATCH 1/2] [auto] fix verbatim-repeat false positive on auth-retry; add subagent thrash detail ## Context - Problem: Two false positives in token_audit.py's detection pipeline. - Trigger: reflect-on-thrash hook fired on a session where the user's prompt hit an OAuth 401 (4 retries, no assistant response), the user interrupted, ran /login, and re-sent the same prompt. The verbatim-repeat detector flagged this as frustrated restatement instead of a legitimate retry after auth failure. ## Considerations - R1 (verbatim-repeat): The detector compared consecutive user messages without checking whether the agent ever responded between them. A re-send after an API error (no successful assistant turn) is a retry, not frustration. Fix: pass assistant JSONL line indices into frustration_signals(); suppress verbatim-repeat when no assistant turn occurred between the two sends. Non-Claude modes (Codex, OMP, Cursor) do not pass this parameter, so they retain the existing behavior. - B2 (subagent thrash detail): The --out JSON reported counts and flag names but not which files were redundantly read or what the recurring failure error messages were. Without specifics, the reflect lenses cannot act on the finding. Fix: expose redundant_read_files and recurring_failure_details in audit_claude()'s return dict, aggregate them per-agent in audit_subagents(). - Alternative for R1: could have checked timestamps of API error responses between user messages, but that requires parsing error shapes per-harness. Checking for the presence of a successful assistant turn is simpler and covers all error types (OAuth, rate limit, network). ## Blast Radius - Files touched: token_audit.py, test_token_audit.py - Risks: Changed the user_msgs ordinal from enumerate-counter to JSONL line index in Claude mode. This only affects the "index" field in flagged frustration output (used for reporting, not for logic elsewhere). Other modes are unchanged. ## Verification - 72 tests pass (69 original + 3 new), 6 subtests pass. - New tests cover: suppression when no assistant between sends, no suppression when assistant did respond, backward compat for non-Claude modes, subagent detail fields populated.

That inverted the discriminator and broke five reflect-on-thrash hook tests plus the e2e five-flags test, because token_thrash_session.jsonl's re-send has no assistant row between the two sends either. ## Considerations - Verified against a real transcript (~/.claude/projects/.../9714ce38-...jsonl line 3486): Claude records an OAuth 401 as its OWN assistant row - isApiErrorMessage true, error "authentication_failed", model "", zero usage, a real message id. The previous rule counted that row as a successful reply, so the motivating false positive still fired; a bare unanswered re-send, which carries no evidence of an outage at all, was silenced instead. - Repro (three shapes, run before and after): real auth-retry FIRED -> suppressed; assistant answered between FIRED -> FIRED; bare unanswered re-send suppressed -> FIRED. - Fix: collect failed_turn_indices from rows carrying isApiErrorMessage or an error code and suppress only when one sits between the two sends. Absence of a reply is not proof of an outage - an unanswered restatement is the frustration signal itself. - Restored test_detects_each_signal_kind_and_counts_interruptions to its origin/main fixture; the three assistant rows inserted into it were only a workaround for the inverted rule. - Rewrote this branch's own new test onto the real API-error row shape and added the bare-re-send case it was missing. Named loudly in the report: that test asserted the inverted contract and contradicted the pre-existing token_thrash_session.jsonl contract; both could not hold. ## Blast Radius - token_audit.py, test_token_audit.py, references/cost-audit.md. - Non-Claude modes (Codex, OMP, Cursor) pass no indices and are unchanged. ## Verification - 5 reflect-on-thrash hook tests + test_cli_all_five_flags_yes: pass. - engine/skills/reflect/scripts/tests: 154 tests, OK. - bash scripts/run_all_tests.sh after npm ci; ruff E9,F; shellcheck install.sh; all 12 CI gate scripts: pass.
