v16.5.2

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

Fixed

• Improved session deadline abort signals to carry structured cancellation reasons, enabling timeout-aware tools to correctly classify deadline cancellations.
• Fixed an issue where completed tool executions were incorrectly marked as skipped (clobbering their actual results) if a user message was queued while the tool was in flight.

@oh-my-pi/pi-ai

Added

• Added OpenAI Codex rate-limit response-header ingestion to proactively refresh account usage snapshots and rotate credentials before hitting 429 errors.

Changed

• Optimized multi-account credential ranking to maximize quota utilization and prevent mid-session blocks by prioritizing expiring quota and demoting heavily used accounts.
• Improved responsiveness of credential blocking by bypassing the usage-ingestion throttle immediately when an account is detected as exhausted.

Fixed

• Fixed empty provider responses (such as from Cloud Code Assist API) being treated as non-retryable, allowing session retries and model-fallback chains to engage.
• Fixed OpenAI Codex watchdog timeouts bypassing transport and session retries by ensuring each request attempt has an independent timeout signal.

@oh-my-pi/pi-catalog

Fixed

• Fixed OpenCode Zen and Go discovery to replace stale bundled models with each provider's live model catalog.

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

Breaking Changes

• Removed the separate selector parameters from read and grep; line ranges and read modes must now be appended to path.

Added

• Added a generate_image.enabled setting (Settings › Tools › Generate Image) to allow toggling the image generation tool.

Changed

• Expanded provider rate-limit response header ingestion to all supported providers with header parsers (previously Anthropic-only), enabling proactive account rotation for multi-account sessions before hitting 429 errors.
• Restored CPU model metadata in workstation prompts on non-Linux hosts.

Fixed

• Fixed omp config list --json output truncation at 64 KiB when stdout is piped.
• Fixed vim-style navigation (h/j/k/l) under the Kitty keyboard protocol.
• Fixed /guided-goal throwing Model not found errors on websocket-only Codex models by routing the interview through the session's provider transport and reusing a single isolated side session.
• Fixed tool_result extension handlers being unable to rewrite the model-visible content of a thrown tool failure.
• Fixed intermittent Perplexity OAuth web search failures (401 errors) caused by transient transport drops on the ask endpoint.
• Fixed the generate_image tool ignoring --no-tools and explicit tool whitelists.
• Fixed markerless prose thinking preambles incorrectly becoming session titles when title models omit the <title> marker.
• Fixed the agent recreating a todo list immediately after a user clears it with /todo rm.
• Fixed internal-URL autocomplete (agent://, skill://, omp://, etc.) not triggering inside slash command arguments.
• Fixed the browser tool hanging indefinitely during tab closure when the headless Chromium process is wedged on Windows.
• Fixed history:// URLs failing to resolve for unregistered, released, or resumed subagents by falling back to scanning artifacts directories on disk.
• Fixed eval cells treating timeout: 0 as a one-second deadline and reporting session-deadline cancellations as user aborts.
• Fixed MCP OAuth dynamic client registration for pathful authorization-server issuers by preserving the discovered registration endpoint.
• Fixed the launch tool failing to start Windows executables due to double-escaped PTY commands and arguments.
• Fixed the built-in advisor warning Advisor unavailable for silent reviews: a content-less stop is a valid "nothing to add" outcome and is never retried or warned about, regardless of reported token usage (#5212 follow-up).
• Fixed read, edit, and grep tools failing on paths with a stray leading colon emitted by some models.
• Fixed git plugin re-installs retaining stale commits by fetching Bun's cached clone before updating the lockfile pin.
• Fixed overlapping Bash timeout and interrupt cleanup to explicitly abort isolated shells instead of leaving child processes running.
• Fixed a bug where generic provider aborts arriving as stopReason: "error" were not auto-retried.
• Fixed switching from a vision model to a text-only model mid-session sending historical image blocks to the new provider.
• Fixed inline images in Agent Hub transcripts by routing replayed images through the shared image budget and Kitty placeholder renderer.
• Fixed OSC 5522 paste in direct API-key login prompts being routed to the hidden main chat editor instead of the focused credential field.
• Fixed plugin installation failures when an ES module extension synchronously requires CommonJS helpers.
• Fixed GitHub code search rejecting empty optional date placeholders.
• Fixed /tree navigation onto a /skill: injection node landing on the incorrect entry.
• Fixed interactive TUI sessions crashing with concurrent JS runtime errors when the JS eval worker falls back to the in-process inline path.
• Fixed compaction aborting instead of trying an authenticated fallback model when Amazon Bedrock credential resolution fails.
• Fixed full-context forks and /tan clones cold-missing OpenAI prompt caches by properly persisting and inheriting provider prompt-cache keys.
• Fixed Codex advisor requests using local session labels as provider session IDs.
• Fixed macOS stdio MCP servers launching in a detached session, allowing the TCC Apple Events permission prompt to trigger.
• Fixed the ask tool timeout to auto-select the recommended option when the UI selector does not settle.
• Fixed LSP workspace diagnostics for Go workspaces to correctly recognize go.work roots and include all used modules.
• Fixed interactive OAuth login success messages waiting on background model discovery.
• Fixed Windows bash tool crashes when an explicit timeout fires while a piped command is still streaming.
• Fixed subagent yield tool calls being discarded when the soft request budget hard-aborted the same assistant turn.
• Fixed --tools filtering in interactive sessions disabling deferred MCP tools.
• Fixed kept-alive task subagents entering repeated provider-call loops after an IRC wake and terminal yield.
• Fixed manual /compact with the snapcompact strategy hard-failing on text-only active models.
• Fixed the empty-editor ←← gesture trapping input when opening the Agent Hub from persisted/parked subagents.
• Fixed eval read() URI handling in Python and JS runtimes to correctly delegate URI reads and pass pagination arguments.
• Fixed discovered plugin .mcp.json stdio servers launching relative command or cwd values against the session cwd instead of the plugin's config directory.
• Fixed Model Hub DEFAULT role assignments with auto retaining a stale concrete reasoning suffix after restart.
• Fixed configured retry.fallbackChains failing to engage on non-retryable provider errors.
• Fixed backgrounded Bash blocks continuing to repaint with live output after completion.
• Fixed --reasoning-slide-plan silently ending the run with no code written when the model answered with a text-only reply.
• Fixed launch tool rendering issues, including stacked pending headers and confusing start/wait results when readiness timed out.
• Fixed the in-process stat and other GNU-flavored shell builtins (such as date, sed, mktemp, tail, find, base64, and ln) mangling or failing on macOS/BSD-style invocations.

@oh-my-pi/pi-natives

Fixed

• Fixed an issue where Windows PTY callers were forced through shell command re-quoting by supporting direct executable and argument launching.

@oh-my-pi/pi-tui

Fixed

• Fixed animated Loader ANSI updates causing unnecessary text layout invalidation and re-wrapping on shimmer-only frames (#5230).
• Fixed Ctrl+W (delete word backward) stopping at underscores in snake_case identifiers, treating them as single words (#4776).
• Fixed automatic file completion incorrectly treating punctuation, trailing spaces, and slash-command text as paths, and improved autocomplete dismissal behavior (#5376).
• Fixed Kitty graphics rendering under tmux, ensuring images correctly follow pane scrolling and reflow (#5381).
• Fixed tmux sessions becoming unresponsive after terminal capability replies by falling back to legacy keyboard input mode when the Kitty protocol is unavailable (#5378).
• Fixed PageUp and PageDown keys on an empty prompt editor incorrectly navigating prompt history instead of scrolling the editor viewport (#4754).

@oh-my-pi/pi-utils

Fixed

• Improved CLI argument and flag validation error output to display a concise error message and command usage instead of a minified code frame.
• Corrected required variadic positionals to render as MODELS... instead of [MODELS] in usage help.
