chore(deps-dev): bump @earendil-works/pi-coding-agent from 0.84.2 to 0.87.1 in /packages/pi-extension - #80

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

v0.87.1

New Features

• Latest frontier models — Use Claude Opus 5.5, GPT-6 Sol, and GPT-6 Luna through supported providers, including GitHub Copilot. See Choose a Model.
• Grok 4.7 by default for xAI — New xAI sessions now default to Grok 4.7. See Provider Authentication.

Added

• Added inherited Claude Opus 5.5, GPT-6 Sol, and GPT-6 Luna support for GitHub Copilot.
• Added inherited GPT-6 Sol and GPT-6 Luna support for OpenAI API keys and OpenAI Codex subscriptions.
• Added inherited Claude Opus 5.5 support for Anthropic with adaptive thinking and a 1M context window.

Changed

• Changed the default xAI model to Grok 4.7.

Fixed

• Fixed split-turn compaction summaries being refused by Claude Fable 5.1 by clearly separating the conversation and using continuation-oriented instructions (#9908 by @​davidbrai).
• Fixed missing or invalid --mode values being silently ignored instead of reporting an error and exiting with a nonzero status (#9045).
• Fixed inherited image-only user messages being rejected by some OpenAI-compatible providers because they included an empty text part (#9797).
• Fixed inherited Anthropic OAuth requests reporting an outdated Claude Code version.

v0.87.0

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.
