Release Notes

earendil-works/pi (@​earendil-works/pi-coding-agent)

v0.87.0

Compare Source

New Features

• Canonical session context and extension boundaries — Edit model context without rewriting history and add actionable lifecycle hooks. See ContextEditEntry and extension events.
• Full-transcript context extensions — Use context_with_system for per-request system-message transformations. See context_with_system.
• Per-model image input limits — Configure cache-safe image resizing per model for attachments, read, and tool-result images. See Image Input Limits.

Breaking Changes

• Removed the inherited shouldStopAfterTurn agent option. Use finishTurn and return { action: "end" } instead. finishTurn runs before turn_end but applies the decision afterward, and it also receives error and aborted responses; migrate normal-response predicates by returning undefined for those hard exits. See the @earendil-works/pi-agent-core changelog for a complete before-and-after example.
• Added ContextEditEntry to the exported SessionEntry union. TypeScript consumers with exhaustive entry switches must handle context_edit; use replacement: null for omission and a content replacement otherwise.
• Made SessionManager canonical for AgentSession provider context. Assigning session.agent.state.messages no longer replaces future request history; restore with SessionManager.inMemory(cwd, { id }, entries), navigate with session.navigateTree(), or append through session.sessionManager and call session.refreshContext().
• Expanded TurnEndEvent with required boundary fields and added AgentBeforeSettleEvent to the exported ExtensionEvent union. Consumers constructing events or exhaustively switching on ExtensionEvent must handle the new shapes. ExtensionRunner.emit() no longer accepts turn_end; host integrations dispatch actionable boundaries with emitBoundary(baseEvent, buildContext).
• Deferred runs requested from agent_settled handlers until all settled handlers finish. Handlers still observe ctx.isIdle() === true, but no longer see a reentrant agent_start during the same notification dispatch.

Added

• Added append-only model-context edits. For example, sessionManager.appendContextEdit(entryId, null) omits one message from future provider context without changing raw history, usage, or UI history.
• Added actionable turn_end and agent_before_settle extension boundaries. Return { entries: [...event.entries, draft], continue: true } to persist structural entries in order and ensure one next provider request without changing steering or follow-up scheduling.
• Added retain-none compaction input: sessionManager.appendCompaction(summary, null, tokensBefore) stores the compaction's own ID as its kept boundary.
• Added the context_with_system extension event, which runs after context handlers on the full transcript including system messages and sends its result verbatim. See context_with_system.
• Added per-model image resize profiles through inputLimits.images.resize in models.json, applied to file attachments, image reads, and tool-result images (#​9631).

Fixed

• Fixed string context-edit replacements producing invalid assistant and tool-result message content instead of text blocks.
• Fixed context-invisible boundary metadata and replacement edits causing newly appended or replaced input to be summarized before its first provider request.
• Fixed edited-context accounting both discarding valid assistant usage captured after the latest context edit and reusing that usage after a later compaction made it stale.
• Fixed selected error retries and final length/overflow recovery retaining abandoned model attempts in future provider context; post-run recovery omissions are now persisted without hiding raw transcript history or changing queue scheduling.
• Fixed context handlers that filter or slice messages dropping the prompt and tool declarations, which after extension-driven compaction left requests without built-in tools or made Codex emit raw tool-call text. Handlers no longer see system messages; Pi restores the prompt and tool state after they run. See context (#​9789, #​9822).
• Fixed /bug allowing uploads in offline mode while preserving local zip exports (#​9841 by @​christianklotz).
• Fixed idle prompt-cache warming rebuilding expired caches when its timer or an extension decision is delayed.
• Improved crash diagnostics with hints identifying loaded extensions that appear in the stack trace.
• Fixed text files beginning with GIF being misclassified as images and omitted from read and CLI @file input (#​9755).
• Fixed malformed prompt template frontmatter being silently ignored instead of reported as a resource warning (#​9830 by @​christianklotz).
• Fixed inherited unknown OpenAI-compatible Chat Completions endpoints receiving strict tool schemas unless they explicitly advertise support (#​9816).

v0.86.1

Compare Source

New Features

• Meta Muse provider — Sign in with Meta using /login meta or use META_API_KEY to access Muse Spark models. See Meta (Muse subscription).

Added

• Added Meta (Muse subscription) login via /login meta with automatic Model API key refresh, plus META_API_KEY support (#​9096 by @​xl0).

Changed

• Enabled Node's persistent compile cache before loading the bundled CLI runtime, reducing repeat launch time.

Fixed

• Fixed /bug descriptions dropping line breaks from pasted diagnostics.
• Fixed /bug hints appearing for user cancellations and retryable provider failures such as service unavailability.
• Fixed clipboard copy failing in containers and WSL without WSLg by restoring the OSC 52 fallback when no display is available, and added a verified Windows clipboard backend for WSL (#​9688).
• Fixed inherited z.ai Prompt too long errors not being recognized as context overflow (#​9805).
• Fixed inherited Cerebras models advertising unsupported strict tool schemas, which caused HTTP 400 errors when strict and non-strict tools were mixed (#​9804 by @​EdenGottlieb).

v0.86.0

Compare Source

New Features

• Prompt cache warming — Keep valuable prompt caches alive during long tool runs and optionally while idle using cost-aware refreshes. See Cache Warming.
• Bug reporting — Report problems with /bug using redacted diagnostics, optional transcripts, or exported ZIP archives. See Reporting Bugs.
• Transcript-aware prompt and tool updates — Preserve instruction and tool changes across resume and branch navigation while retaining cached prefixes. See before_agent_start.
• Offline Radius model catalog — Select Radius models immediately, with cached and live catalogs overlaid when available. See Radius.
• Per-model compaction budgets — Configure reserved and recent-token budgets by model. See Per-model overrides.

Breaking Changes

• Changed inherited pi-ai provider stream inputs from Context to normalized TranscriptContext values. Custom providers must read system prompts and tool declarations from context.messages with getCurrentSystemPrompt() and getCurrentTools(). See Custom Streaming API.
• Restricted inherited ToolCall.arguments and ToolResultMessage.details to JSON-compatible values, changed ToolResultMessage into a conditional type, and made JsonValue arrays readonly.
• user_bash now fails closed: errors or invalid defined results abort the command without invoking later handlers or executing locally. Return undefined to continue propagation; otherwise return { operations } or { result } (#​9068).

Added

• Added transcript-backed mid-conversation system prompt and tool changes so instruction and tool updates survive resume and branch navigation while preserving cached prefixes on supported models. See before_agent_start and Entry Types (#​9548).
• Added inherited native deferred tool loading for Fireworks Messages models. Use ToolSearch or tool_search as the loader name for prompt-prefix deferral (#​9323).
• Added click toggling for branch summaries, compaction summaries, and skill invocation entries.
• Added the public Radius model catalog for immediate and offline model selection, with cached and live gateway catalogs overlaid when available.
• Added ctx.modelRegistry.stream() and streamSimple() for extension model calls through configured providers with resolved authentication (#​8964).
• Added per-model reserveTokens and keepRecentTokens settings through compaction.modelOverrides, with ordinary compaction settings as fallback (#​8133).
• Added compat.allowedFallbackModels configuration for overriding or disabling Anthropic server-side fallback models (#​9294).
• Added an unsubscribe function from pi.on() so extensions can drop event handlers. Handlers added or removed during a dispatch apply to later dispatches, not the current one (#​8967).
• Exported extension hook event and result types that were previously omitted from the package entry points (#​9642).
• Added /bug [description] to report a bug to the Pi developers. The report bundles environment, model, provider, extension, and settings metadata (secrets redacted), assistant message diagnostics from the session, optionally the session transcript, or a model-written summary of what went wrong instead. It is uploaded to Radius (no login required; attributed when logged in) or exported as a zip archive, and the report id is recorded in the session as a pi.bug-report entry. Crashes are recorded in ~/.pi/agent/crashes.json, announced once on the next start, and attached to the next report; unexplained errors and exhausted retries point at /bug once per session.
• Added cost-aware prompt-cache warming during long tool runs and optionally while idle, with configurable modes, model cache-lifetime metadata, /session diagnostics, transcript notices, and the cache_warming_decision extension event. See Cache Warming (#​9668).

Changed

• Enabled Node's persistent compile cache before loading the bundled CLI runtime, reducing repeat launch time.
• Made --resume session results appear progressively, using file modification times to prioritize all-folder loading and cancelling outstanding transcript reads after selection.
• Reduced --continue startup time by checking candidate session headers in modification-time order and stopping after the newest matching session.
• Replaced the external native clipboard dependency with bundled asynchronous macOS, Windows, and X11 helpers while preserving platform command and OSC 52 fallbacks (#​9163).
• Reduced inherited fuzzy search latency for long texts by using native substring search instead of scanning each character in JavaScript (#​9267).
• Moved compaction, branch summarization, and retry spinners into the editor border alongside the working indicator. Custom editors use the same embedding opt-in for all status spinners.
• Enabled strict-prefer JSON-schema sampling by default for built-in read, bash, powershell, edit, and write tools, without requiring PI_EXPERIMENTAL. Extensions can re-register tool definitions with constrainedSampling: false.
• Formatted Bash and PowerShell tool durations of at least one minute as minutes and seconds, with hours when needed (#​9628).
• Deferred the extension compiler and bundled virtual modules until a filesystem extension is loaded, reducing the baseline SDK import cost (#​9540).

Fixed

• Fixed GitHub Copilot GPT models, including GPT-6 Astra, using the Chat Completions adapter instead of the required Responses adapter (#​9253 by @​petrroll).
• Fixed inherited DeepSeek V4.1 thinking levels on OpenRouter and OpenCode Go preserving provider effort metadata (#​9485).
• Fixed inherited bodyless HTTP 400/413 errors from non-Cerebras providers being misclassified as context overflow (#​9482).
• Fixed inherited Vercel AI Gateway replaying unsigned thinking as assistant text (#​9676).
• Fixed inherited Google Generative AI and Vertex AI using unsupported thinking levels when reasoning is omitted or when model capabilities differ within a Gemini family (#​9455).
• Fixed inherited Anthropic-compatible relays breaking signed thinking replay when they report a different response model, while preserving fallback pricing (#​9188).
• Fixed inherited Amazon Bedrock one-hour cache writes being priced at the five-minute rate (#​9457).
• Fixed inherited quadratic CPU usage when draining buffered EventStream events (#​9055).
• Fixed inherited Mistral Medium reasoning requests to use reasoning_effort for all reasoning-capable mistral-medium-* model IDs instead of the unsupported prompt_mode (#​8700).
• Fixed inherited OpenCode and OpenCode Go requests to send x-opencode-session from sessionId across all supported API adapters (#​9326).
• Fixed inherited OpenAI Codex requests to send the model's Off reasoning effort instead of omitting it, while respecting unsupported Off mappings (#​9191).
• Fixed inherited Fireworks unsigned thinking replay and reasoning effort selection using catalog metadata, with verified DeepSeek V4 and Qwen3.8 fallbacks and removal of redundant GLM 5.2 and Kimi K3 effort aliases (#​9323).
• Fixed inherited OpenRouter requests to send x-session-id from sessionId for Chat Completions and Anthropic Messages models when prompt caching is enabled (#​9102).
• Fixed the inherited DeepSeek catalog to advertise deepseek-flash for DeepSeek V4.1 Flash instead of retired Flash aliases, and refreshed DeepSeek pricing metadata (#​9423).
• Fixed inherited Mistral-hosted GLM-5.2 reasoning requests to use reasoning_effort instead of the ignored prompt_mode (#​9375).
• Fixed inherited OpenAI-compatible Responses errors to identify the actual provider instead of always labeling them as OpenAI errors (#​9298).
• Fixed inherited Baseten requests to send session-affinity headers from sessionId for automatic prompt-cache routing (#​9629).
• Fixed inherited retry classification for Cloudflare 520 responses (#​9627).
• Fixed inherited retry classification for transient Azure peak-load capacity errors (#​9669).
• Fixed session tree navigation racing with active compaction and replacing its progress UI (#​9179 by @​acmerfight).
• Fixed exact session ID lookup scanning complete transcript bodies instead of reading session headers (#​9601 by @​metaist).
• Fixed repeated Anthropic thinking-drop notices being shown for the same dropped blocks, and shortened notices while retaining details in the session (#​9391).
• Fixed mid-run threshold compaction silently skipping oversized trailing tool results (#​9740).
• Fixed signal-terminated local shell commands being reported as successful with partial output (#​9577 by @​BrendanJMurphy).
• Fixed local clipboard failures reporting success when the terminal ignored the fallback OSC 52 write, and added platform-specific setup guidance when no clipboard backend works (#​9618).
• Capped agent-level retry backoff at retry.maxAgentDelayMs (60s by default) so long retry runs stay responsive during prolonged transient outages (#​8826).
• Fixed direct RPC steer and follow_up commands bypassing extension input handlers (#​8718).
• Fixed premature missing-model errors after login by waiting for catalog discovery. Radius now defaults to balanced, falling back to the first available Radius model when needed.
• Fixed fullscreen mode reserving a blank row for custom footers that render zero rows (#​8919).
• Fixed extension tools without parameter schemas to be rejected during registration instead of breaking provider requests (#​9300).
• Fixed before_agent_start handlers returning systemPrompt (and forceSystemPrompt) on models with mid-conversation system messages: the forced prompt is now sent as the provider's leading system prompt instead of being appended as a section patch after the original prompt.
• Fixed loaded llama.cpp models with enable_thinking chat templates ignoring Pi's thinking level (#​9528).
• Fixed cancellation races that could start automatic compaction, leave stale retry state, or miss cancellation while waiting for summarization authentication (#​9340, #​9777).
• Fixed asynchronous Kitty image conversion replacing newer partial tool output images (#​8743 by @​wutongyuonce).
• Fixed inherited skill slash-command autocomplete ranking the skill: prefix instead of the bare skill name (#​9120 by @​yearth).
• Fixed inherited file autocomplete boundaries and path quoting around CJK punctuation (#​9746 by @​haoqixu).
• Fixed inherited LaTeX legacy font switches falling back to raw source, centered cases layouts around surrounding equations, and vertically laid out unsupported and nested display scripts (#​8827, #​9564, #​7929).
• Fixed inherited fullscreen Kitty images being erased by later row clears in WezTerm (#​9169).

Removed

• Removed unavailable inherited GPT-5.4 and GPT-5.4 mini models from OpenAI Codex selection (#​9394).
