Hi @Vadevious — the shape of this is right: repeatedCallIn requiring the tail to equal the block exactly is a properly conservative predicate, and "mismatched markup remains visible" is the correct default for a suppressor. Your 6 focused tests pass for me on 7d0fab3.
I poked at the boundaries of that exactness, since narrow predicates on model output tend to be narrower than intended. Two gaps and one non-gap.
A. A trailing newline after the second block leaks a bare block
if (text.slice(first.end) !== block) return undefined;text.slice(first.end) is everything after the first block, so any trailing character makes it unequal and the double-block path declines. The single-block path from #5674 then suppresses one, and the other reaches the user as raw markup:
input: block + block + "\n"
output: "<tool_call><function=exec>const names = []; text(names);</parameter></function></tool_call>\n"
A trailing newline after a tool-call block is about as ordinary as model output gets, and this is the exact symptom the PR exists to remove. Everything else in the PR is already trim-aware (inputFromArguments(...)?.trimEnd() === repeated.body.trimEnd()), so this line looks like the one that didn't get the treatment:
if (text.slice(first.end).trimEnd() !== block.trimEnd()) return undefined;with end then needing to stay text.length so the trailing whitespace isn't re-emitted mid-suppression — worth a test either way round.
B. A newline between the blocks is fine — I was wrong about this one
Recording it so nobody re-checks it later:
input: block + "\n" + block
output: "\n" ← both blocks suppressed, separator preserved
The separator survives and both blocks go. That's the right answer and it already works.
C. Doubled input joined by a separator isn't repaired
(parsed as Record<string, unknown>).input === body + bodyExact concatenation only. With a newline between the copies, the repair declines and the tool receives the code twice:
input: {"input": script + "\n" + script}
output: {"input":"const names = []; text(names);\nconst names = []; text(names);"}
which is the "duplicated code then failed to execute" failure from the description, one separator away from the case you fixed. Given body is already trimEnd()ed, a "\n"-joined double seems at least as likely as the bare one — the model producing the doubled input is the same one that put a newline between the blocks in B.
If you'd rather keep the predicate maximally tight, that's a defensible call — I'd just suggest saying so in the ADR, because the next person to see a doubled input in the wild will read this code and assume it was meant to cover them.
How I checked
Five cases against your head, each direction controlled so a pass isn't a coincidence:
ok two adjacent identical blocks are suppressed (control)
ok repair collapses exactly-doubled input (control)
ok a newline BETWEEN the blocks still suppresses (B — works)
FAIL a trailing newline after the second block (A)
FAIL doubled input joined by a newline (C)
Happy to push A and C as test cases on your branch if that's useful — say the word and they're yours, no credit needed. A alone seems worth fixing here; C is defensible as a follow-up if you'd rather keep the scope where it is.

…ifies Review follow-up to the #5693 carry: the doubled-input repair ran per structured call, so two qualifying calls were both rewritten while the pair itself stayed visible as ambiguous. Both flush sites now reconcile a response's calls as one batch, and the reduction applies only when exactly one call qualifies.
…5693) MiMo 2.6 Pro over OpenCode Go can echo two identical bare <tool_call> blocks in assistant text beside one structured call whose input repeats the body twice. The pair is now suppressed when exactly one structured call agrees with its function and input, and a doubled input (direct or newline joined, input as the only key) is reduced to one copy. Ambiguous or mismatched markup stays visible. Rebuilt on the blockAt/freeformBody reader from #5725, so the comparison also holds for the canonical MiMo layout with a newline after the function header.

…xAI adapter fixes (#5739) * fix(quota): label DeepSeek balance with the selected row's currency (#5692) A CNY-billed account showed 'API balance ($76.88)'. The symbol now follows the balance_infos row that was picked: USD keeps $, CNY uses ¥, other codes prefix the amount, and a row without a currency keeps the legacy $. * fix(registry): publish MiMo token-plan context, output and modality facts (#5695) The mimo token-plan entry declared no model-level capacity, so V2.6 rows reached clients without a context window, output cap or input modalities. Xiaomi's model pages list 1M context and 128K output for all four roster ids, image input for V2.6 Pro/Flash and V2.5, and text only for V2.5 Pro. Video/audio have no catalog vocabulary and are not claimed; noVisionModels is unchanged. * fix(google): give array tool parameters without items a string item schema (#5689) A tool parameter declared as {type: array} with no items reached Gemini unchanged and could be rejected. The sanitizer now materializes items {type: string} for any array it emits without items (missing, tuple, or invalid source items). Valid item schemas are unchanged, the budget-exhausted path is untouched, and no loss category is recorded. * fix(openai-chat): reconcile repeated MiMo tool-call echoes (carries #5693) MiMo 2.6 Pro over OpenCode Go can echo two identical bare <tool_call> blocks in assistant text beside one structured call whose input repeats the body twice. The pair is now suppressed when exactly one structured call agrees with its function and input, and a doubled input (direct or newline joined, input as the only key) is reduced to one copy.

Rebuilt on the blockAt/freeformBody reader from #5725, so the comparison also holds for the canonical MiMo layout with a newline after the function header. Co-authored-by: Vadevious <Vadevious@users.noreply.github.com> * fix(xai): give grok-4.7-build-fast grok-4.7's documented metadata (#5576) The discovered grok-4.7-build-fast id fell back to a 128K window and a generic effort ladder. xAI documents Grok 4.7 Fast as the same model on faster infrastructure (Cursor and Grok Build only), so the id now carries grok-4.7's 500K window, low..xhigh ladder with a high default, image input, and the reasoning-model stop/penalty/reasoning-replay lists. The wire pin, service tier and lineup seed stay unclaimed until probed. * fix(cli): resolve Codex catalog slugs in ocx effort model (#5096) ocx effort model command-code/deepseek-deepseek-v4.1-flash, the slug the Codex catalog publishes, reported an empty ladder because the selector was split at the first slash and looked up literally. The model part now decodes through the router's known-id slug codec before the ladder, wire map and noReasoningModels lookups, so the slug and the exact id command-code/deepseek/deepseek-v4.1-flash report the same ladder. Output names the resolved id and adds requestedModel / 'Resolved from' when it differs. Unresolvable ids behave as before; no ladder rows change. * fix(command-code): keep MiMo tool-call markup after prose off the text channel (#5698) The Command Code tool-text filter only held a text block that opened with <tool_call>. MiMo's gateway echo can arrive after ordinary prose in the same delta, and interleaved reasoning interrupted held blocks, so the raw envelope reached the client while the native call also ran. - A delta is split at the marker: prose keeps its streamed or queued path and the markup starts a fresh probe block. Leading whitespace still uses the existing probe. - Held blocks are no longer interrupted by interleaved events; the queued byte bound still flushes an envelope that never resolves. - An envelope the strict parser rejects but that opens and closes around a declared function is dropped on the duplicate and clean-finish paths. Markup that parses but does not fit its schema is still released as text. Reimplemented from the reporter's validated patch in the issue. Co-authored-by: marciodps <95321123+marciodps@users.noreply.github.com> * docs(command-code): describe the prose split, held envelopes and loose-envelope drop (#5698) * test(layout): register L3 regression files; add the L3 lane plan * fix(google): charge synthesized array items to the schema node budget (#5689) Review follow-up: the materialized items schema was added after traversal without consuming a node, so many bare array leaves could exceed the 1,024-node bound. Synthesis now reserves one node and is skipped, with node-budget-widened reported, once the budget is spent. * fix(openai-chat): reduce a doubled echo input only when one call qualifies Review follow-up to the #5693 carry: the doubled-input repair ran per structured call, so two qualifying calls were both rewritten while the pair itself stayed visible as ambiguous. Both flush sites now reconcile a response's calls as one batch, and the reduction applies only when exactly one call qualifies. * fix(command-code): drop a malformed echo only for its own native call; track only probing blocks Review follow-ups to #5698: a malformed envelope was dropped when any native call exhausted its candidates, even one for another tool; it now needs a native call for the function it declares, otherwise it is released as text. Held blocks are no longer kept in activeProbes just to be skipped on every event. * fix(openai-chat): count an already-agreeing call as a competing echo explanation Review follow-up: with a doubled call A and a call B whose input already equals the repeated block, A was still reduced because only doubled shapes were counted. Both now count as explanations, and the reduction applies only when there is exactly one. * fix(google): omit an array the node budget cannot complete instead of emitting it bare Review follow-up to #5689: when the budget ran out at an array, the retained array could still be emitted without items, which Gemini rejects for the whole request. Every sanitizeSchema exit now completes an array's items or returns BUDGET_EXHAUSTED so the caller omits it, cascading to a parent that lost its own items. Non-array schemas keep the existing budget behaviour. * test(openai-chat): pin fenced repeated echoes as visible and unrepaired Review follow-up: a repeated pair inside a Markdown fence opened in an earlier chunk keeps its doubled input and stays visible, and a fenced echo does not repair the argument prefix beside it. The buffer never holds a complete block inside a fence, so the reducer and drain share the same starting context; these tests guard that. --------- Co-authored-by: Vadevious <Vadevious@users.noreply.github.com> Co-authored-by: marciodps <95321123+marciodps@users.noreply.github.com>
