What
Sub-agents that exhaust their tool-round budget now get one more last turn in which they must answer from everything gathered so far, instead of failing hard with
Max tool rounds exhaustedand discarding all work.How
AgentOptions.finalAnswerOnMaxRounds(defaultfalse— behavior unchanged for all existing callers). Also exposed onOpenRouterClient.createAgent,Agent.createSubAgent(inherited, overridable), andSubAgentTool.onMaxRoundsReachedhook, if set, stops granting additional rounds — the agent injects a final[System]instruction ("no further tool calls are possible; respond now with your final answer from the information gathered so far, stating which parts are complete and which remain unfinished") and runs a single completion with tools stripped from the request, so the model cannot keep looping.AgentResponse.hitMaxRoundsis set so callers can distinguish a salvaged answer from a naturally finished run.ToolMessageso the persistent conversation never carries danglingtool_calls(which OpenAI-compatible APIs reject on the next turn).SubAgentToolwith the flag enabled prefixes salvaged results with a one-line notice ([Sub-agent reached its tool-round limit and returned its findings so far; parts of the task may be unfinished]) so the orchestrator knows the task may be partially incomplete and can re-delegate if needed. A salvaged run with no content reports exhaustion, not completion.Tests
hitMaxRounds, salvage request carries notools, ends on a rogue tool call (with the conversation staying valid across a follow-upchat()), runs afteronMaxRoundsReacheddeclines, returns leaked-markup answers as success, andcreateSubAgentinheritance/override.Sub-agent error: Max tool rounds …) is unchanged.dart test),dart analyzeclean (3 pre-existing infos).Addresses the angela-assistant request: sub-agents should return their gatherings instead of failing hard when out of turns.

🔮 fufu~ Jibril reviewed your code!
Oh? Oh! Salvaging a sub-agent's gathered work instead of throwing everything away when the round budget dies — such a kind feature~ And carefully built, too: opt-in, tools stripped at the request level so the model physically cannot keep looping, hook-before-salvage ordering documented in the comments... I was having so much fun reading it! ♡
But then I merged your branch against current master in a scratch clone, and fufu... the smile stayed, but something sharper arrived. You wouldn't leave THIS in production, would you? ♡
Verdict: ⛔ I can't let this pass~
⛔ These need fixing before I'm satisfied~
lib/src/agent/agent.dart:284 (PR head; :331 post-merge) — the salvage turn discards its own salvaged answer once merged with current master. Your branch is based on
27c9fef, but master has since gained8a713c0("fix: recover when models leak tool-call markup into text content"), whose recovery logic sits inside the very no-tool-calls branch your salvage turn now enters. Trace it: the salvage answer comes back with content that merely contains<tool_call>/<arg_key>/<arg_value>markup — exactly what round-burning GLM-family models emit — →looksLikeLeakedToolCallmatches → correctiveUserMessageadded,continuefires → but the salvage for-loop budget is 1, so the loop just ends →salvageis alreadytrue, so the secondifdeclines →Result.fail('Max tool rounds (2) exhausted'). Every finding the model reported is thrown away — the precise failure this PR exists to kill, resurrected by the merge. Proven empirically: probe test (salvage response whose content embeds leaked markup,maxToolRounds: 1) → PASS at543e93c(hitMaxRounds: true, content returned), FAIL on merge with436b956(hard failure=Max tool rounds (2) exhausted). Your 575/575 was honest — at your merge-base this path didn't exist. On the tree this PR will actually land on, it's a live regression.Fix: the leaked-markup corrective is nonsense in the salvage turn (there are no tools to "re-issue through the proper mechanism" — you stripped them!). Guard it:
if (!salvage && content != null && looksLikeLeakedToolCall(content) && leakedToolCallRetries < maxLeakedToolCallRetries)— a markup-tainted salvage answer is still the final answer.test/agent/agent_test.dart — no regression pin for the interaction above. Once fixed per #1 it must be tested: a salvage turn whose content contains leaked tool markup still returns
isSuccess+hitMaxRounds: truewith content intact. Unwritable at your current merge-base, mandatory at the new one — fufu~ a code path born from the merge with no test? I can't let that live unpinned~ ♡ (Two sequential responses,maxToolRounds: 1, salvage content embedding<tool_call>{"name":"add"}<arg_key>a</arg_key><arg_value>2</arg_value></tool_call>— ten lines.)CHANGELOG.md:20-23 + pubspec.yaml — rebase required; the entry lands in released history. Your bullet sits under
## 0.24.0— unreleased when you branched, but three releases ago now (master is at 0.27.0). Post-merge your feature would live inside an already-shipped release's notes with no version movement, while every feature commit in this repo bumps the minor and opens a fresh top section (7c35b96: 0.26.0→0.27.0 + new section). Please rebase onto current master (you'll want that anyway to fix #1 against the real code), move the bullet to a new## 0.28.0section, and bumppubspec.yamlto 0.28.0.💡 Little ideas (non-blocking)~
createSubAgentdoesn't forwardfinalAnswerOnMaxRounds. Precedent is genuinely mixed (parallelToolCallsis forwarded;onMaxRoundsReachedandmaxInlineImagesare not), so I shan't hold it against you~ But this feature's stated purpose is sub-agents; a parent running with salvage on silently loses it forcreateSubAgentchildren. One parameter + one forwarding line if you agree.hitMaxRoundsnotice. A salvage turn returning null/empty content (rogue tool call, nothing said) reportsSub-agent completed but returned no content.— "completed" is a small lie there; it exhausted its rounds. CheckinghitMaxRoundsfirst (or folding it into that message) keeps the orchestrator correctly informed.✅ What I liked~
salvage ||condition explaining why the rogue call can't be honored is exactly the kind of why-comment I adore~hitMaxRoundsas an explicit documented discriminator, defaultfalse— zero drift for existing callers.toolCallsInRound: toolCalls?.length ?? 0reports unexecuted rogue calls instead of pretending nothing happened.tools— pinning the wire format, not internal state.

## 0.24.0section, andpubspec.yamlstays at0.27.0. Every feature commit in this repo's recent history does the opposite: bump the version and create a new section —134fc40(→0.25.0),b7485cd(→0.25.1),5d6e18d(→0.26.0),7c35b96(→0.27.0), and yes,a6947dacreated 0.24.0 itself. Three releases have shipped since 0.24.0; you are retroactively rewriting what that released version contained. This library is consumed via git-pinned submodules (doujin-manager, angela-assistant) — a new public API surface (AgentOptions.finalAnswerOnMaxRounds, thecreateAgentparam, theSubAgentToolparam,AgentResponse.hitMaxRounds) is precisely what a minor-version bump signals to pin-consumers. Right now the feature ships unlabeled and the 0.24.0 changelog becomes a lie.Fix: bump

createSubAgent) — The new flag is neither inherited from the parent agent (parallelToolCalls: options.parallelToolCallsis threaded there, by its own introducing commita6947da) nor passable as a parameter — so an orchestrator running with salvage enabled cannot give a manually orchestrated sub-agent the same courtesy. The codebase is admittedly split on this (maxInlineImages,injectToolImages,onMaxRoundsReachedaren't threaded either — pre-existing gaps), andSubAgentTool— the path this PR actually targets — does expose it. Still, consider addingfinalAnswerOnMaxRounds: options.finalAnswerOnMaxRounds(or a parameter) so manual orchestration matchesSubAgentToolsemantics.[SYSTEM], while its synthetic-message siblingleakedToolCallCorrective(agent.dart:57) uses[System]. Downstream consumers (angela) have[-prefix conventions for synthetic user turns, so both work — but one casing would be prettier.content == null || content.isEmptybranch wins) and the orchestrator sees the generic "returned no content" instead of the tool-round-limit notice. Arguably fine (nothing was salvaged), just be aware the notice only rides along when there's something to ride with.✅ What I liked~
salvage ||short-circuit for the rogue-tool-call end,!salvageguard on the leaked-markup retry (acontinuethere would burn the one-round budget and hard-fail — the comment explaining this is chef's kiss), tools stripped via the ternary, hook-before-salvage ordering,roundOffsetaccounting intact across extensions, andsalvageas a local so a reused Agent resets cleanly. I traced every one.salvage ||, un-stripping tools, dropping the!salvageguard, deleting the SubAgentTool notice, and flipping hook/salvage order — and each probe reddened exactly the corresponding test. Not a tautology in sight. The rogue-tool-call test assertingcontainsKey('tools'), isFalseon the captured request is particularly satisfying~hitMaxRoundsdesign — success-shaped with an honest flag, plus the[Sub-agent reached its tool-round limit…]notice so the orchestrator can re-delegate — is exactly the right contract for partial results. And defaulting tofalsekeeps every existing caller byte-compatible.dart analyze= 3 pre-existing infos (allreasoning_detail.dart, untouched — matches your claim), full suite 626/626 with--concurrency=1.Fix the versioning and I'll approve with the biggest smile~ fufufu ♡

Oh? Oh! A salvage turn for exhausted sub-agents~ What a lovely idea — instead of burning all gathered work on a hard failure, squeeze one final answer out of the model. The opt-in wiring is clean, the tests pin the wire format… I was having so much fun reading this. And then~ ♡ I ran your own rogue-tool-call test scenario one turn further, and the conversation state left behind made my wings twitch. Let's talk~
Verdict: ⛔ I can't let this pass~ ♡
⛔ These need fixing before I'm satisfied~
lib/src/agent/agent.dart:305 + :331 — A rogue tool call in the salvage turn leaves dangling
tool_callsas the last message of the persistent conversation, poisoning every subsequent turn. The flow::305adds the rawassistantMsg(tool_calls included) to_conversation, then theif (salvage || …)branch at:331returns immediately — the calls are never executed, so noToolMessages ever answer them. Your own test (salvage turn omits tools and ends even on a rogue tool call) constructs exactly this scenario, so it's a first-class supported path, not an exotic one. I probed it in my clone: after a rogue salvage on a persistent agent, the nextchat()sends[user, assistant, tool, …, assistant(tool_calls=1), user]— an assistant message withtool_callsfollowed by ausermessage. OpenAI-compatible APIs reject that with a 400 ("assistant message with 'tool_calls' must be followed by tool messages"), and Anthropic-strict upstreams likewise refusetool_useids withouttool_resultblocks. So the salvaged run succeeds, and the very next turn of that agent dies. Note this is newly introduced: on master, every path that persists anassistant(tool_calls)message appends itsToolMessagesbefore any budget check fires, so the failure path never leaves the conversation malformed.SubAgentToolitself escapes (fresh agent per call, state discarded) — but the flag is public oncreateAgentfor any persistent agent, exactly the angela-assistant usage pattern.Fix: in the salvage end-branch, don't leave the rogue calls unanswered — either strip them from the message that gets persisted (
AssistantMessage(content: …, reasoningContent: …, reasoningDetails: …)withouttoolCalls), or append one syntheticToolMessageper rogue call id (e.g."Error: no further tool calls are possible in the final turn"), which also keeps the history honest about what the model tried. And pin it: a regression test that runs a rogue salvage and then either assertsagent.messagescontains no unansweredtool_callsor drives a secondchat()successfully. The current tests stop at the return value and never look at the conversation afterward — fufu~ you added a state-corrupting code path but forgot to test the state? I can't let that slide~ ♡CHANGELOG.md:21–24 + pubspec.yaml:3 — The feature bullet was appended under
## 0.24.0, a shipped version (0.25.0, 0.25.1, 0.26.0 and 0.27.0 sections all sit above it, and pubspec history walks 0.23.0→0.24.0→…→0.27.0 monotonically), andpubspec.yamlstays at0.27.0. Every sibling feature commit in this repo did the opposite:a6947da(parallelToolCalls) bumped 0.23.0→0.24.0 with a new top section,5d6e18d(video) →0.26.0,7c35b96(maxInlineImages) →0.27.0 — each with its own fresh## X.Y.Zheading. As merged, the changelog falsely tells a reader that the salvage turn shipped in 0.24.0, and the feature is invisible in every version ≥ 0.25.0 — for a doc whose entire job is per-version truth. A new opt-in API surface (AgentOptions.finalAnswerOnMaxRounds,AgentResponse.hitMaxRounds, new params oncreateAgent/SubAgentTool) is a minor bump by this repo's own convention.Fix: add

createSubAgentdoesn't forwardfinalAnswerOnMaxRounds(noronMaxRoundsReached,imageDescriber, …).

Only[tools]is truly not inherited (tools: tools, no fallback → a child starts toolless unless given its own). This library is consumed via git pins by orchestrators (angela-assistant!) — someone reading "resets to its defaults" will assume each child gets a fresh 10-round budget and silently get the parent's custom one instead.

I re-probed it ata01d30awith a fresh two-turn test: after a rogue salvage on a persistent agent, the nextchat()sends[user, assistant, tool, …, assistant(tool_calls=1), user]— my probe asserts the wire payload and fails withmessages[8] assistant(tool_calls) followed by user. OpenAI-compatible APIs reject that shape with a 400 (assistant message withtool_callsmust be followed by tool messages); Anthropic-strict upstreams refusetool_useids withouttool_resultblocks the same way. So the salvaged run succeeds, and the very next turn of that agent dies. This is newly introduced: on master, every path that persists anassistant(tool_calls)appends itsToolMessagesbefore any budget check fires.SubAgentToolitself escapes (fresh agent per call — verifiedsub_agent_tool.dart:134), but the flag is public oncreateAgentfor any persistent agent.Fix (verified working in my clone): in the salvage end-branch, answer the rogue calls — one synthetic
ToolMessageper call id before returning:I applied exactly this, re-ran my probe → wire shape clean (
… assistant → tool → user), and the full suite stays green: 629/629 (628 existing + my probe). Alternatively striptoolCallsfrom the persisted message — but the synthetic answers also keep the history honest about what the model tried. Either way: pin it with a test — a persistent agent, rogue salvage, secondchat(), assert noassistant(tool_calls)in the outgoing messages lacks a followingtoolmessage (or simply that the second turn succeeds).lib/src/agent/agent.dart:193-195— the newcreateSubAgentdoc comment misdescribesmaxToolRounds. (From comment 6570 — still open, two words.) It reads: "[finalAnswerOnMaxRounds] is inherited from this agent's options when not overridden — unlike [tools] and [maxToolRounds], which reset to their defaults." But:213doesmaxToolRounds: maxToolRounds ?? options.maxToolRounds— the child inherits the parent's budget, the identicalparam ?? options.parampattern. Only[tools]truly resets (tools: tools, no fallback). A pin-consumer reading "resets to its defaults" will assume each child gets a fresh budget and silently get the parent's custom one. Fix: dropmaxToolRoundsfrom the "unlike" clause.💡 Little ideas (non-blocking)~

Round six~ and this is the dance I live for. You took the round-5 blocker — the one that survived a whole review round unnoticed — and fixed it exactly the way I asked, then pinned it at the wire level. And your request back to me? Fair. This round I fetched the head SHA (

Round six~ and oh, oh! Now this is what I wanted to see! ♡ I re-fetched the head SHA before probing this time (yes, I heard your request-back, matikane — this whole review ran against a fresh clone of

✅ What I liked~
ToolMessage("Error: no further tool calls are possible in the final turn; the run ended with the best answer available.") — inserted atagent.dart:346-357, after the assistant message lands in the conversation (:312) and before the run returns. The history stays valid (assistant(tool_calls)→tool) and honest about what the model tried. I traced the wire serialization myself:role: tool+tool_call_id— the exact shape OpenAI-compatible APIs demand. Fufu, keeping the conversation both valid and truthful — you know the way to my heart~createAgent+finalAnswerOnMaxRounds: true) and then — the crucial part — chats again on the same agent, asserting the follow-up succeeds and pinning the wire format: everytool_calls-bearing assistant message in the captured request is followed by atoolmessage. That's a wire-level pin, not a state-level tautology.Expected: contains 'call_rogue',Actual: Set:['call_1']— the dangling id, exactly the round-5 bug). Restored → green.

Harmless little passenger — delete it or give it a real job (e.g. assert the answeringToolMessage's id equalscall_rogue, not just that the set contains it). ♡Fix the PR body whenever convenient and merge when ready — the code itself I'm completely satisfied with. All blockers from rounds 1–5 are now verifiably closed at this head. My smile has fully returned~ fufufu ♡
