This post reviews every major SmartPerfetto change since the previous three-week update (2026-06-04, v1.0.28), through 2026-07-17 (v1.1.1). By the end, you will understand the problem each feature solved over these six weeks, where its boundaries lie, and the full feature map of the current release. Project repository: github.com/Gracker/SmartPerfetto.
The previous SmartPerfetto update was published on May 17. At that point the project had already moved from “an AI Assistant inside Perfetto UI” to “a reusable trace analysis platform.” By June 4, the new work is concentrated in five areas: Smart Mode, selected-range quick analysis, CLI capture, stronger evidence rules for Power / ANR / Input / IO / Network, and four Agent runtimes.
This article is based on the SmartPerfetto main branch on June 4, 2026. The latest public release at this point is v1.0.28. The goal is simple: list what changed after May 17, explain how runtimes and evidence sources are handled, and show what information makes a useful bug report.

When I wrote the SmartPerfetto open-source introduction on April 29, the headline was still “put an AI Assistant that can run SQL, invoke Skills, and generate reports inside the Perfetto UI.” Two weeks later the repository has moved a long way. The feature surface expanded from single-trace Q&A to reusable analysis results, multi-trace comparison, dual Claude/OpenAI runtimes, SQL guardrails, evidence-source indexing, no-install packages, rendering-pipeline teaching, and a more complete Provider diagnostic flow.
This article is based on the SmartPerfetto repository state as of May 17, 2026, and adds a new feature description on top of the previous post. Readers should walk away knowing three things: what was added in the past two weeks, where the current full feature boundary sits, and what information a good bug report should include.

SmartPerfetto is now fully open source. Open the repository and you can see the runnable mainline project as it exists today: the Perfetto UI fork, the agentv3 backend, MCP tools, YAML Skills, scene strategies, scripts, and documentation. There is no private core module kept outside the repository, and this is not just a thin demo shell.
The project comes from a very concrete daily workflow: you have a trace in hand, Perfetto has already exposed the facts, but moving from facts to judgment still means jumping through tables, writing SQL, matching threads, checking FrameTimeline, finding the Binder peer, and then returning to the timeline to confirm everything again. SmartPerfetto tries to turn those repeated actions into tools, so performance engineers can spend more time on judgment.
It is still in development. I am releasing it now because trace analysis grows from real samples: real devices, real vendor differences, real product traces, and real PRs all change how Skills and strategies should be written. Waiting until every capability is stable before publishing it one way would miss the stage where samples matter most.
If you often open Perfetto to inspect scrolling jank, startup, ANR, Binder, CPU scheduling, or rendering pipelines, SmartPerfetto provides a Perfetto UI with an AI Assistant. After loading a trace, you ask questions in natural language. The backend queries trace_processor_shell, invokes YAML Skills, organizes evidence, and streams conclusions plus data tables back into the browser.

For normal trial use, you only need the main repository. Gracker/perfetto is the frontend fork used by the perfetto/ submodule. It mainly matters to developers who want to modify the AI Assistant plugin UI.
The previous two technical articles are better for readers who want the engineering details:
- From Trace to Insight: Harness Engineering in SmartPerfetto AI Agent: the architecture of the SmartPerfetto AI Agent and the Harness Engineering process.
- SmartPerfetto Architecture Q&A: 8 In-Depth Technical Questions: Q&A around the Agent, Workflow, and YAML Skills.
Those two articles go deep into the internal architecture. Once the source is public, readers usually care more about what is actually in the repository, whether it can run, and which parts are not stable yet. This article focuses on the open-source release itself: what is open, what works today, how the internal pieces are divided, how to run it locally, and where collaboration is most useful.
