@oh-my-pi/pi-agent-core

Added

• Anthropic server-side compaction as a remote compaction backend: model lines the beta supports (compat.supportsServerCompaction, rule-owned in the catalog: Opus 4.6+, Sonnet 4.6+, Fable/Mythos 5) on the official endpoint, resolved the way the provider routes requests, plus Anthropic-compatible routes with remoteCompaction.enabled, compact by re-issuing the live turn's own request — same system prompt, tools, and history, so it reads the prompt cache the last turn wrote — with the compact_20260112 edit paused after the summary and the harness summary prompt as instructions. The instructions name where the retained tail begins so the summary covers only the history the rebuilt context drops. The API's summary is stored as the entry text and as preserveData.anthropicCompaction, replayed natively on later Anthropic requests and read as plain text by every other provider; the retained tail comes from session entries as with a local summary. Contexts below 55k tokens (the API trigger floor plus margin) keep summarizing locally, and a response without a summary is a native failure, like the OpenAI lanes. An aborted compaction response is the abort (a cancellation, never a native failure) and an error response keeps its HTTP status, so auth and timeout classification match the OpenAI lanes; the block's opaque encrypted_content is persisted as preserveData.anthropicCompaction.encryptedContent and replayed verbatim.

Fixed

• compact() now forwards the caller's oneshotRetry opt-out to every summarization oneshot; auto-compaction's outer retry loop no longer multiplies with the inner transient-failure retries.

@oh-my-pi/pi-ai

Added

• Anthropic server-side compaction (compact-2026-01-12 beta): anthropicCompaction on StreamOptions sends the compact_20260112 context-management edit, the streamed compaction block is surfaced as an anthropicCompaction provider payload, the compaction stop reason is a normal stop tagged in stopDetails (exempt from the empty-completion retry), and usage sums usage.iterations whenever a compaction iteration ran. A user-role compaction summary carrying that payload replays as a leading assistant compaction block — folded into the retained assistant turn when one follows — with the beta and a never-firing strategy attached automatically; other providers keep reading the summary text. Everything compaction-related is gated on the model line (compat.supportsServerCompaction, rule-owned in the catalog) and on the endpoint the request actually reaches (supportsAnthropicCompaction: the official API for the first-party provider, resolved through Foundry / ANTHROPIC_BASE_URL reroutes, or an explicit remoteCompaction.enabled opt-in), so a rerouted session or an older model line falls back to the text summary instead of sending a block the API rejects. Caller-owned clients are gated on their own endpoint (the client's baseURL, or an explicit remoteCompaction.enabled opt-in when it exposes none) and receive the compaction beta per request, like the effort and control betas. A block held by its originating assistant message — a caller that appends the compacting response itself — replays at the head of that turn. The block's opaque encrypted_content is captured from the stream, kept on the payload as encryptedContent, and replayed verbatim. A compacting turn is priced per sampling iteration (like a server-side fallback turn), so a long-context tier applies only to an iteration whose own prompt crosses the threshold, never to the summed totals.


• Added historical decimation prompt-cache breakpoints every 15 user turns on Anthropic requests, so long conversations retain stable cached prefixes during branching, rewinds, and session resume ().

Changed

• Defaulted Anthropic OAuth requests to 1h prompt-cache retention where supported, matching Claude Code subscriber behavior and preventing cache expiry during idle intervals ().

Fixed

• Fixed Codex HTTP response-body transport failures forwarded through Anthropic-compatible proxies being treated as terminal errors; replay-safe turns now use the existing transient recovery without re-executing completed tools.


• GitHub Copilot Enterprise requests keep the Copilot CLI identity accepted by private Enterprise endpoints, and Business requests denied with HTTP 400 model_not_supported now retry once as the Copilot CLI (matching the existing 403 fallback), restoring models that 18.1.17 rejected as unsupported ().


• GitHub Copilot streams remember the working Copilot-Integration-Id per credential after a denied chat identity retries as the Copilot CLI, so later streams start at the working shape instead of replaying the denial ( by ).

@oh-my-pi/pi-catalog

Added

• supports-server-compaction compat axis (compat.supportsServerCompaction): whether a model line accepts Anthropic server-side compaction (compact-2026-01-12). Class rules enable it for Opus 4.6+, Sonnet 4.6+, and Fable/Mythos 5 on every Anthropic-messages host; the default is false.

Fixed

• OpenCode Go's DeepSeek Flash lanes (deepseek-flash, deepseek-v4.1-flash) now declare image input. The gateway serves them with vision despite the IDs carrying no vision suffix, so the class-wide strip-image-input rule was dropping attachments the endpoint reads; the modality is declared too, since live discovery seeds these lanes text-only ().


• Amazon Bedrock OpenAI models, plus unclassified profiles such as opaque application-inference-profile ARNs, now carry the compatibility policy required to preserve image-bearing tool results ().

@oh-my-pi/pi-coding-agent

Added

• Enable tui.mouse to focus live subagent cards and jump-list rows by clicking them, with a hover highlight on the target; native selection becomes Shift+drag while on ().


• The pinned Subagents block now lists every live agent, collapsed to a few rows with a click expander by default; display.pinnedAgents switches it to full or off ().


• The remote compaction method now covers Claude: Anthropic server-side compaction (compact-2026-01-12 beta) runs behind the existing compaction.methodOrder / compaction.remoteEnabled gates for first-party Anthropic models, persists its plain-text summary with a native replay payload that later Anthropic turns send back as a compaction block, and falls through to the next configured method on failure like OpenAI server compaction.

Changed

• The providers.cacheRetention auto setting now keeps Anthropic OAuth subscriber sessions on 1h prompt-cache retention and API keys on 5m, instead of 5m for both ().

Fixed

• Provider-native compaction (OpenAI Responses compact, Anthropic server-side compaction) re-issues the system prompt the live turn actually sent — a per-turn before_agent_start override included — instead of the rebuilt base prompt, and advisor compaction sends the advisor's own prompt instead of the generic summarizer prompt, so the request reads the live request's cached prefix.


• The set_steering_mode, set_follow_up_mode, and set_interrupt_mode RPC commands are now session-scoped, so a short-lived RPC client no longer silently writes queue-mode fields to the machine-global config.yml. The setters still persist by default, so the settings panel and existing callers are unaffected ().


• models.yml now validates the per-model compat.stripImageInput opt-out, so a wrong-typed value is rejected like every other declared compat key instead of being silently accepted ().


• Fixed isolated tasks dropping nested-repo work: nested diffs persist as <agent>.nested-*.patch before cleanup, apply=false lists each file, isolated agents report as non-resumable, and runs needing manual recovery report failed ().


• Fixed the Windows PowerShell installer (install.ps1) aborting on Windows PowerShell 5.1 when bun or git wrote normal progress to stderr: native commands now run with $ErrorActionPreference scoped to Continue and success is gated on the process exit code, so $ErrorActionPreference = "Stop"'s stderr-as-terminating-error behavior no longer kills the install ().


• Models whose images are stripped on the wire (compat.stripImageInput) now trigger the describeForTextModels vision fallback and are skipped when resolving the vision model, instead of silently dropping images ().


• A malformed project .claude/settings.json now produces a warning instead of being silently ignored ( in in in in in in ) by
