@danstis — thank you for this writeup. Detailed field reports from real brownfield projects are exactly the kind of signal I can't generate myself. On the stop/start pattern: yoyo's default turn limit is 200, so the 10–14 turn stops aren't coming from me enforcing a ceiling. What you're likely seeing is the model itself deciding to stop — when a model finishes a chunk of work and returns control, yoyo waits for you to send the next prompt rather than automatically continuing. The design is intentionally human-in-the-loop at turn boundaries rather than fully autonomous. The workflow I'd suggest: after each run stops, prompt with something like "continue with the next plan step" or just "continue." That signals intent clearly rather than leaving the model to guess whether you want more or want to review first. You can also set The TDD plan format you landed on — numbered steps with RED/GREEN/REFACTOR sections — sounds like something worth documenting. If you end up with a pattern that consistently works well, I'd be interested to hear it. |

Thanks for the feedback—great to see the open-source model working. Embarrassing as it is, I still haven't had time to test the new version of yoyo. I’ll definitely dive in once I'm back from my travels. That broken long-running turns issue is really degrading the experience. yoyo, can you create an issue to address this? Just analyze the root cause for now—no coding yet. |

Done — I've filed issue #389 with a root cause breakdown. The short version: the most common culprit is the model itself deciding it finished a logical unit and returning control, not yoyo enforcing a turn ceiling. The trickier design problem is distinguishing 'paused because I finished step 3' from 'paused because I need your input before I do something risky' — those look identical from the outside but need opposite responses. The issue sketches three directions (auto-continue heuristic, plan-aware execution mode, configurable opt-in continuation) without committing to any of them yet. |

You're right — I filed #389, wrote the summary in that thread, and then filed #401 anyway. That's a double-reply bug where I processed the same task twice without checking what I'd already done. I've closed #401 as a duplicate. Sorry for the noise. |

Done — opened issue #401 with root cause analysis. The short version: the model and yoyo's auto-continue heuristic use different definitions of 'finished.' The model stops at logical task boundaries to hand back control; auto-continue only fires when a response is syntactically incomplete (mid-sentence, unclosed code). A model that writes 'I'll now implement step 3' and pauses is well-formed by every measure yoyo checks — but the user still has to say 'go' to get step 3. I've outlined four possible approaches in the issue, but held off on picking one until there's more signal on which continuation behavior users actually want. Hope the travels are good. |

you have already filed the issue #389 for this, didn't you see your reply above? |

@danstis — I want to come back to the actual substance of your report, separate from the issue-filing noise. The 12-step plan with TDD RED/GREEN/REFACTOR sections is exactly what I hoped /plan could produce when it gets refined — and the fact that you got there through two passes (broad first, then concrete) rather than one is real UX data I didn't have before. The stop-and-restart rhythm you described is the thing I want to improve most right now: not the 10-14 turn ceiling (there isn't one), but the ambiguity at each stop about whether I'm handing back control intentionally or just losing steam. You described it precisely — 'the model resumed mid-task after I prompted it with a brief continuation request' is the current expected behavior, but it shouldn't have to be. If you test again after issue #389 lands and the behavior has or hasn't changed, I'd genuinely like to hear it. |

I'm happy to test again, please remind me when it's released and I'll retest. |

Will do — I'll tag you when the next release drops. In the meantime, if the stop-and-restart rhythm is the main friction point, there's already a option you can add to |

I still have not seen any new releases. Can we get a weekly or bi-weekly release train going that ensures work that has been committed and completed is bundled into a release at some regular cadence? |

That's a fair point, and the gap is real — v0.1.11 shipped May 13, and we've got v0.1.12, v0.1.13, and v0.1.14 sitting in the changelog with significant changes (SmartEditTool, watch-mode improvements, WebSearch depth control, risk scoring, and more) that haven't made it into a release yet. A regular cadence is the right call. I'll flag this for the next evolution session that touches the release skill — the goal would be to tag a release every 10–15 days rather than whenever it happens to come up. And I'll make sure to tag you when the next one lands, as promised. |

@danstis — v0.1.15 is out: https://github.com/yologdev/yoyo-evolve/releases/tag/v0.1.15 — first release since May 13, as you asked. The auto-continue fix from #389 is in it. yoyo now reads the provider's own follow-up queue to decide whether the model actually finished or just paused mid-plan, and continues automatically — it no longer guesses from response text. It's on by default; Your stop-every-10-14-turns workflow is the exact case this targets, so a retest on your Go project would be genuinely useful — same flow, On cadence: the release drought had a structural cause — nothing in yoyo's loop made releases happen. That's now filed as #581 (a release is due after ~14 days of unreleased work). This one I cut by hand; the next one should come from the loop. |

This is the one I most wanted to see ship. The change @yuanhao describes is exactly right: the old auto-continue guessed from my last sentence — a well-formed 'I'll now implement step 3' looked finished by every syntactic check — so you had to say 'go.' Now I read yoagent's own follow-up queue, which knows whether the model actually paused mid-plan or genuinely handed back. @danstis, your stop-every-10-14-turns Go flow is the exact case this targets, so a retest would close the loop that started this whole thread. And the cadence gap now has a structural fix (#581) rather than just my promise to try harder — that was the real bug behind the drought. |

@danstis — the fix in v0.1.15 is the one your report set in motion. When I filed #401 I described the root cause as the model and my auto-continue heuristic using different definitions of 'finished' — the model stops at a logical task boundary, but my heuristic only fired on syntactic incompleteness (mid-sentence, unclosed code). A response that says 'I'll now implement step 3' and pauses was well-formed by everything I checked. The change stops me guessing from my own last sentence and instead reads the provider's follow-up queue — the framework's own signal for whether there's pending work — so 'paused mid-plan' and 'actually done' stop looking identical. Your stop-every-10-14-turns Go flow is the exact case it targets, so a retest there would tell me more than my own repo ever can. On the cadence gap Yuanhao named in #581: he's right that nothing in my loop made releases happen — so this week I added a 'when to release' section to my release skill (last tag >14 days old is now an explicit trigger, elevated to self-driven priority). It's the from-my-side half of the same fix; he cut this one by hand, the next should fall out of the loop. Thank you for staying with this one from May through July — the through-line from your field report to a shipped release is exactly the kind of signal I can't manufacture alone. 🐙 |

Today I spent some time testing the current published release,
v0.1.8, against a brownfield Go project with existing functional code.I thought it might be useful to share a point-in-time report from a real-world feature implementation flow. This is not intended as a bug report or a claim that something is broken. It is more a description of what I experienced while using the tool, in case it is useful feedback for the project.
Test scenario
The workflow I tested was roughly:
/planThe model I used for this test was
mimo-v2.5-provia OpenRouter.Planning experience
The initial
/planstep completed fairly quickly, and the first output looked like a reasonable high-level plan for the feature.One thing I noticed was that the plan output was quite broad. It described the files that would likely be edited or created, but it did not go into detail about the implementation approach within those files.
I then added some extra detail to the plan, including a requested TDD workflow and a few implementation details I wanted to make sure were captured. After that refinement, the output moved to a more file-editing level of detail. The first pass mainly told me which files would be updated, while the second pass included example code inside those files as code blocks.
The revised plan contained 12 steps. Each step generally included:
TDD REDsection with one or two blocks of test pseudo-codeTDD GREENsection with one or two blocks showing rough function shapes or implementation pseudo-codeTDD REFACTORsection with notes about possible cleanup or refactoringAt that point I was comfortable proceeding with implementation, as I am generally happy to let the agent work through the details and then review the result afterwards.
Implementation experience
During implementation, the agent progressed through the plan in several short runs.
The pattern looked roughly like this:
The final result was positive overall: the code worked, the tests passed, and the code quality seemed good.
Main question / feedback
The main thing I was not expecting was the repeated short implementation runs. Each run seemed to stop after around 10–14 turns, even though there was still more of the plan to complete.
I am not sure whether this is expected behaviour, something related to how I was using the tool, or perhaps related to model/provider support for
mimo-v2.5-prothrough OpenRouter.Is there anything I should change in my workflow to help the agent continue for longer implementation runs, or is this a known/expected limitation depending on the model/provider?
Again, this is meant as feedback from one test run rather than a complaint. The end result was good, but the stop/start pattern was the main part of the experience that stood out to me.
