Thanks for the review and merge! Looking forward to the next release — I've been saying a little prayer every time I queue a follow-up message over the poor SSH connection. 😭 |

See [TUI Fullscreen Viewport](docs/keybindings.md#tui-fullscreen-viewport). - **Configurable default tools** — Choose startup built-in tools globally or per project. See [Tools](docs/settings.md#tools). - **Configurable fullscreen exit output** — Print the transcript or only a resume hint on exit. See [Interactive Mode](docs/usage.md#interactive-mode). ##### Added - Added fullscreen transcript search with `Ctrl+Shift+F`, incremental match highlighting, configurable search match theme colors, and next/previous navigation with `Enter`/`Ctrl+G` and `Shift+Enter`/`Ctrl+Shift+G`. - Added experimental strict JSON-schema constrained sampling for the default `read`, `bash`, `edit`, and `write` tools under `PI_EXPERIMENTAL=1`. - Added a fullscreen exit output setting to choose between printing the final transcript and only a session resume hint. - Added the `defaultTools` setting for configuring the initial built-in tool selection globally or per project. - Added `--use-theme <name[/name]>` to choose an initial per-run interactive theme without changing saved settings ([#​7722](earendil-works/pi#7722) by [@​rwachtler](https://github.com/rwachtler)). - Added `expandPromptTemplates` to extension `pi.sendUserMessage()` options for explicitly dispatching commands and expanding skills and prompt templates. See [`pi.sendUserMessage()`](docs/extensions.md#pisendusermessagecontent-options) ([#​7857](earendil-works/pi#7857) by [@​mrexodia](https://github.com/mrexodia)). - Added inherited `createGatewayBindingFetch()` for routing Cloudflare AI Gateway requests through a Workers AI binding without an API token ([#​7901](earendil-works/pi#7901) by [@​Maximo-Guk](https://github.com/Maximo-Guk)). - Added inherited `AssistantMessage.endTurn` to preserve OpenAI Codex's terminal `end_turn` signal for diagnostics ([#​7766](earendil-works/pi#7766)). - Added inherited unbound single-line transcript scrolling actions for fullscreen mode. See [TUI Fullscreen Viewport](docs/keybindings.md#tui-fullscreen-viewport) ([#​7903](earendil-works/pi#7903) by [@​midastruth](https://github.com/midastruth)). ##### Changed - Changed inherited Kimi Coding requests to use pi's runtime `User-Agent` header. - Replaced the inherited Mistral SDK transport with a native Chat Completions HTTP stream, eliminating its generated client and schema runtime overhead. - Documented the generic `AI_AGENT=pi` process marker and how it differs from `PI_CODING_AGENT=true` ([#​7747](earendil-works/pi#7747)). - Changed inherited OpenAI Responses deferred tool loading to prefer message-anchored `additional_tools` where supported while retaining tool-search and top-level fallbacks ([#​7709](earendil-works/pi#7709)). - Reduced inherited fullscreen rendering allocation churn by painting full-width layout rows directly instead of recompositing them on every frame. ##### Fixed - Fixed root Markdown files such as `README.md` and `AGENTS.md` in skill directories being reported as broken skills unless they declare valid skill frontmatter ([#​7805](earendil-works/pi#7805)). - Fixed single-object `edit` tool inputs failing validation by accepting them as one-edit arrays in both coding-agent and harness edit tools ([#​7835](earendil-works/pi#7835)). - Fixed managed-tool downloads delaying TUI startup and hiding diagnostics in fullscreen mode by mounting the TUI first and showing download progress and warnings inside it. - Fixed opening a model selector immediately after startup cancelling and restarting the in-progress model catalog refresh. - Fixed inherited GitHub Copilot login triggering API rate limits while enabling model policies by limiting concurrent policy updates ([#​6187](earendil-works/pi#6187)). - Fixed fullscreen transcript search snapping back to the current match during manual scrolling and fragmented mouse input leaking into the search query. - Fixed inherited required LaTeX arguments starting on a new line being parsed as empty ([#​7760](earendil-works/pi#7760)). - Updated the transitive `nanoid` development dependency to address a denial-of-service vulnerability. - Fixed fallback rendering for extension tool results to collapse long output and honor tool expansion ([#​7979](earendil-works/pi#7979)). - Fixed JSON and RPC `message_update` events dropping cumulative usage during streaming. See [JSON Event Mode](docs/json.md) and [RPC `message_update`](docs/rpc.md#message_update-streaming) ([#​7982](earendil-works/pi#7982) by [@​christianklotz](https://github.com/christianklotz)). - Fixed `pi.sendMessage(..., { triggerTurn: false })` steering an active run instead of only recording the custom message ([#​8022](earendil-works/pi#8022) by [@​cristinaponcela](https://github.com/cristinaponcela)). - Fixed the `defaultTools` setting dropping extension and SDK custom tools when selecting built-in defaults. - Fixed the subagent example rejecting YAML array syntax for the `tools` frontmatter field ([#​7598](earendil-works/pi#7598) by [@​alexsavio](https://github.com/alexsavio)). - Fixed the subagent example dropping parent session model, thinking, and tool configuration ([#​7897](earendil-works/pi#7897) by [@​virtuald](https://github.com/virtuald)). - Fixed custom system prompts concatenating the current working directory with later appended prompt content ([#​7887](earendil-works/pi#7887) by [@​distributedlock](https://github.com/distributedlock)). - Fixed inherited OpenAI Responses function and custom tool calls losing namespaces during streaming, proxying, and replay ([#​7709](earendil-works/pi#7709)). - Fixed inherited upstream request buffer failures not triggering automatic assistant retries. - Fixed inherited built-in and custom DeepSeek API models sending output limits through an unsupported field. - Fixed inherited Amazon Bedrock replay rejecting tool arguments that contain empty object keys while preserving all valid nested values ([#​7882](earendil-works/pi#7882) by [@​muyiyr](https://github.com/muyiyr)). - Fixed inherited DeepSeek compatibility detection for base URLs whose hostname contains uppercase letters ([#​7933](earendil-works/pi#7933) by [@​yearth](https://github.com/yearth)). - Fixed inherited Google Generative AI and Vertex AI responses with tool calls incorrectly treating output-limit or provider-error stops as normal tool use ([#​8059](earendil-works/pi#8059)). - Fixed inherited fullscreen mouse drag selection and OSC 8 link activation in terminals that report generic SGR mouse release button codes ([#​7963](earendil-works/pi#7963)). - Fixed inherited focused fullscreen overlays not receiving mouse wheel or viewport scroll keys such as PageUp and PageDown ([#​7894](earendil-works/pi#7894)). - Fixed inherited LaTeX control spaces split across line endings causing complete expressions to fall back to raw source. - Fixed split `Alt+Enter` input over SSH being misread as Escape, added `PI_TUI_ESC_TIMEOUT` for high-latency terminals, and limited that timeout to lone Escape input ([#​7899](earendil-works/pi#7899) by [@​powerfooI](https://github.com/powerfooI)). - Fixed inherited idle fullscreen sessions repainting and clearing text selection when the terminal loses focus ([#​7892](earendil-works/pi#7892) by [@​terrorobe](https://github.com/terrorobe)). - Fixed fullscreen selection copy to use the host clipboard and report failure instead of claiming success when OSC 52 is unsupported ([#​8110](earendil-works/pi#8110) by [@​Panoplos](https://github.com/Panoplos)). </details> --- ### Configuration 📅 **Schedule**: (UTC) - Branch creation - At any time (no schedule defined) - Automerge - At any time (no schedule defined) 🚦 **Automerge**: Disabled by config.

Problem
Without the Kitty keyboard protocol, Alt+Enter arrives as
ESC+CR. If stdin delivers the bytes more than 10ms apart,StdinBufferflushes the loneESC, which coding-agent handles asapp.interrupt, aborting the active turn.Change
SSH_CONNECTIONorSSH_TTYis present.PI_TUI_ESC_TIMEOUToverride for other high-latency terminal paths.ESC+CR, key parsing, timeout selection, and Kitty negotiation timing.This adds at most 90ms to bare Escape dispatch over SSH while avoiding destructive Alt+Enter misclassification.
Validation
