chore(deps-dev): bump @earendil-works/pi-ai from 0.85.1 to 0.86.1 in /packages/pi-extension

[dependabot]

Bumps @earendil-works/pi-ai from 0.85.1 to 0.86.1.

Release notes

Sourced from @​earendil-works/pi-ai's releases.

v0.86.1

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

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).

Changelog

Sourced from @​earendil-works/pi-ai's changelog.

[0.86.1] - 2026-09-20

Added

• Added Meta provider (Model API key and Muse subscription OAuth) with Muse Spark models (#9096 by @​xl0).

Fixed

• Fixed z.ai Prompt too long errors not being recognized as context overflow (#9805).
• Fixed Cerebras models advertising unsupported strict tool schemas, which caused HTTP 400 errors when strict and non-strict tools were mixed (#9804 by @​EdenGottlieb).

[0.86.0] - 2026-09-19

Breaking Changes

• Changed provider-facing ProviderStreams and StreamFunction inputs from Context to normalized TranscriptContext values. System prompts and tool declarations now live in transcript system messages; custom providers must read them with getCurrentSystemPrompt() and getCurrentTools(). See System Messages.
• Restricted ToolCall.arguments and ToolResultMessage.details to JSON-compatible values, changed ToolResultMessage into a conditional type, and made JsonValue arrays readonly.

Added

• Added transcript-backed mid-conversation system prompt and tool changes, with native replay on supported models and automatic collapse for other providers. See System Messages (#9548).
• Added a generated public Radius model catalog for synchronous API lookup, with cached and live gateway catalogs overlaid at runtime.
• Enabled native deferred tool loading for Fireworks Messages models. Use ToolSearch or tool_search as the loader name for prompt-prefix deferral (#9323).
• Added RetryPolicy.maxAgentDelayMs support to cap shared assistant retry backoff for summarization calls (#8826).
• Added Model.promptCache lifetime metadata for short and long retention tiers to support prompt-cache warming decisions (#9668).

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 DeepSeek V4.1 thinking levels on OpenRouter and OpenCode Go preserving provider effort metadata (#9485).
• Fixed bodyless HTTP 400/413 errors from non-Cerebras providers being misclassified as context overflow (#9482).
• Fixed Vercel AI Gateway replaying unsigned thinking as assistant text (#9676).
• Fixed 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 Anthropic-compatible relays breaking signed thinking replay when they report a different response model, while preserving fallback pricing (#9188).
• Fixed Amazon Bedrock one-hour cache writes being priced at the five-minute rate (#9457).
• Fixed quadratic CPU usage when draining buffered EventStream events (#9055).
• Fixed Mistral Medium reasoning requests to use reasoning_effort for all reasoning-capable mistral-medium-* model IDs instead of the unsupported prompt_mode (#8700).
• Fixed OpenCode and OpenCode Go requests to send x-opencode-session from sessionId across all supported API adapters (#9326).
• Fixed OpenAI Codex requests to send the model's Off reasoning effort instead of omitting it, while respecting unsupported Off mappings (#9191).
• Fixed 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 OpenRouter requests to send x-session-id from sessionId for Chat Completions and Anthropic Messages models when prompt caching is enabled (#9102).
• Fixed the DeepSeek catalog to advertise deepseek-flash for DeepSeek V4.1 Flash instead of retired Flash aliases, and refreshed DeepSeek pricing metadata (#9423).
• Fixed Mistral-hosted GLM-5.2 reasoning requests to use reasoning_effort instead of the ignored prompt_mode (#9375).
• Fixed OpenAI-compatible Responses errors to identify the actual provider instead of always labeling them as OpenAI errors (#9298).
• Fixed Baseten requests to send session-affinity headers from sessionId for automatic prompt-cache routing (#9629).
• Fixed retry classification for Cloudflare 520 responses (#9627).
• Fixed retry classification for transient Azure peak-load capacity errors (#9669).
