- Replaced project, subagent, and system prompt templates to use bracket-style `[TAG]...[/TAG]` markers instead of `<|START_*|>`/`<|END_*|>` markers.
- Updated system-prompt and subagent reminder tests to assert the new bracket tag format for role, context, and contract blocks.
- Added an Unreleased changelog entry for the subagent batch registry initialization behavior.
- Replaced `===== ... =====` eval cell headers with `*** Begin ` / `*** End ` markers; legacy format remains renderable in HTML exports.
- Replaced hashline patch grammar with `*** Begin Patch` / `*** End Patch` envelope; old inputs without the envelope are still accepted.
- Extracted `sniffEvalLanguage` into a shared `sniff.ts` module reused by the parser and tool.
- Added `docs/ERRATA-GPT5-HARMONY.md` and `scripts/session-stats/harmony_backtest.py` documenting and backtesting the GPT-5 Harmony-header leak defect.
- Deleted `bash-normalize.ts` and its tests; output truncation is handled by the streaming tail buffer and artifact spillover.
- Removed `head`/`tail` schema fields from `bashSchema` and `BashToolInput`.
- Updated system prompt and bash tool prompt to forbid `| head`/`| tail` pipes and other anti-patterns, directing the agent to use dedicated tools instead.
- Added immutable metadata to protocol handlers and had the router copy each handler's setting onto resolved internal resources.
- Updated read and search tools to honor `resource.immutable`, and made search suppress hashline anchors only for immutable source paths while preserving them for mutable files.
- Expanded internal URL tests to cover mutable local resources and mixed immutable/mutable search input hashline behavior.
- Added explicit prompt markers and wrappers across system templates, including `[env]`, `[role]`, `[coop]`, `[closure]`, and `[now]`.
- Removed `renderTemplate` and `sectionSeparator` flows, deleted `task/template.ts`, and switched to per-task `renderSubagentUserPrompt` rendering.
- Updated system prompt assembly to `shortenPath`-normalize `cwd`, append rendered now metadata, and preserve trailing `[now]` blocks.
- Removed legacy template tests and added prompt-composition tests for ordered `[contract]`->`[project]`->`[now]` blocks and context-only system placement.
- Reworked shared prompt utilities by collapsing consecutive blank lines and removing obsolete `OPENING_HBS`/`LIST_ITEM` helper behavior.
- Extended splitPathAndSel to detect compound selectors that combine a line range with `raw` in either order.
- Updated read selector parsing to support `:lines:raw` and `:raw:lines` selectors and propagate raw-mode handling through internal URL, archive, and notebook paths.
- Added tests covering compound selector syntax and confirming it returns verbatim content without anchors or line-number prefixes.
- Extended file-display resolution to accept an immutable flag and suppress hashline anchors when immutable sources are requested.
- Plumbed immutable propagation through ReadTool and SearchTool so internal URL reads and searches pass that context.
- Added a regression test confirming artifact:// search output no longer includes hashline anchors.
- Added `listWorkspace` native binding and API types, exporting bounded workspace trees with AGENTS.md candidates.
- Reworked `buildWorkspaceTree` and `buildDirectoryTree` to call `listWorkspace` with 5s timeout defaults.
- Replaced startup AGENTS.md discovery with workspace-tree-only scanning and removed legacy AgentsMdSearch session plumbing.
- Updated `WorkspaceTree` and system prompt context to expose `agentsMdFiles` and aligned tests/changelog expectations.
- Dropped the `modify` edit type and its `< ANCHORTEXT` / `+ ANCHORTEXT` syntax.
- Removed associated parser rules, regex patterns, apply logic, and tests.
- Deleted the "Append WITHIN a line" example from the prompt docs.
- Added a 30s timeout for extension handlers in runner.ts so stalled callbacks now emit warnings and stop.
- Consolidated duplicated extension handler error handling by routing calls through #runHandlerWithTimeout.
Reporter screenshot showed a parent session on DeepSeek V4 Pro dispatching
a task subagent that resolved to `qwen3.6-plus-free` — an opencode-zen
model the user had no working credentials for. The dispatch hit a
provider that could not serve the model and surfaced a confusing API
rejection instead of using the parent's already-authenticated model.
Adds `resolveModelOverrideWithAuthFallback`, an auth-aware wrapper
around `resolveModelOverride` that checks the resolved subagent model's
credentials via `modelRegistry.getApiKey` + `isAuthenticated` and
falls back to the parent session's active model pattern when the
primary has no working auth. The parent's active model is plumbed
through `ExecutorOptions.parentActiveModelPattern` from `TaskTool`
into `runSubprocess`. If neither has working auth (or they resolve to
the same model), the primary resolution is preserved so the existing
error path still surfaces a meaningful failure downstream.
Fixes#985
- Model resolver: provider-prefixed `<provider>/<id>` selectors are now
strict. If the provider is known and the exact pair does not resolve,
return undefined instead of silently crossing provider boundaries
(e.g. routing `anthropic/claude-3-7-sonnet` to amazon-bedrock when
the user only has Anthropic auth). Unqualified resolution is unchanged.
- Compaction: when the current model's provider has no credentials,
manual compaction now retries across compaction model candidates and
falls back to an authenticated role; if no usable fallback exists, it
throws a clear provider-specific pre-stream error instead of bubbling
a 503 `auth_unavailable` from the provider stream.

Adds an opt-in onSseEvent callback across HTTP-streaming providers (Anthropic, OpenAI Responses/Completions, Azure OpenAI Responses, OpenAI Codex SSE, Google Gemini CLI, GitLab Duo, Kimi, Synthetic) so callers can inspect raw SSE frames without altering parsed output. Provider fetch wrapping only tees response bodies when an observer is wired; standalone packages/ai consumers without onSseEvent are not penalized.
Adds streamIdleTimeoutMs (env: PI_STREAM_IDLE_TIMEOUT_MS, with PI_OPENAI_STREAM_IDLE_TIMEOUT_MS as a backward-compatible alias). Anthropic now enforces a steady-state idle watchdog (default 120s) in addition to the first-event watchdog. OpenAI Responses, Azure Responses, and Codex (SSE + WebSocket) gain a semantic-progress predicate so response.in_progress-style keepalives no longer keep stalled tool calls alive forever.
Adds a coding-agent debug-panel raw SSE viewer backed by a per-session bounded buffer (1000 records / 512KB) that AgentSession populates unconditionally so users can post-hoc inspect a stuck stream from the TUI.
- Updated the hashline grammar to require a full `LID .. LID` range for block operations.
- Enhanced `parseRange` to reject single-anchor syntax and malformed ranges, and to require duplicated anchors for one-line edits.
- Reworked hashline prompt examples/tests accordingly and added coverage for single-anchor delete/replace forms.
- Replaced regex-based import rewriting in `rewriteStaticImports` with Babel AST parsing.
- Handled default, namespace, named, and side-effect imports, preserving `import ... with` options.
- Returned original source on no top-level imports, parse failures, or unchanged non-import regions.
- Added `@babel/parser` dependency and tests/changelog coverage for top-level static-import rewrite behavior.
- Added `./hashline` package exports and redirected callers to the new hashline entrypoint.
- Moved hashline logic out of `edit/` to `src/hashline` and removed `edit/modes/hashline`/`edit/line-hash` paths.
- Added hashline parsers, anchors, types, and diff helpers with stricter input and mismatch validation.
- Implemented preflight and cache-recovery execution flows to reapply edits and handle stale anchor mismatches.
- Documented the hashline API relocation as breaking changes in `CHANGELOG.md`.
- Removed hashline anchor auto-rebase logic, including the ±5-line rebase window and `tryRebaseAnchor` fallback.
- Validation now reports hash mismatches directly as hard `HashMismatch` entries and surfaces them via `HashlineMismatchError` without mutating anchor lines.
- Updated the changelog to document anchor auto-rebase removal and the immediate re-read recovery behavior.
- Updated LSP diagnostics output to return "OK" when no issues were found.
- Added a diagnostics-specific render case to show successful status and a success label for "OK" responses.
- Updated the regression test to expect the new "OK" diagnostics output.
- Added asynchronous Kitty conversion for assistant tool images using `convertToPng`, keyed per tool-call entry with cached and in-flight tracking.
- Updated assistant image rendering to prefer converted PNGs for Kitty terminals while preserving existing behavior for other protocols.
- Added a unit test that verifies WebP tool images are converted and rendered as Kitty image output instead of the raw image/webp fallback.
- Updated ExtensionUIContext, InteractiveModeContext, and InteractiveMode to require editor factories to return CustomEditor instances.
- Removed the runtime compatibility guard and warning for non-CustomEditor implementations in setEditorComponent.
- Removed the test that verified rejection of non-CustomEditor factories in interactive-mode editor-component tests.
- Render each exit_plan_mode submission as a fresh plan review entry so refined plans are emitted into terminal scrollback.
- Keep external-editor edits replacing the current preview instead of adding duplicate review entries.
- Updated the plan review regression test to preserve the first preview and append the second one after intervening chat content.
- Implemented hashline stale-anchor recovery using cached reads and a 3-way merge fallback.
- Updated hashline execution and preflight checks to retry mismatched anchors through cache recovery.
- Added file-read cache support with per-session LRU snapshots and contiguous/sparse record APIs.
- Integrated read and search tools with the shared cache to record candidate lines for recovery.
- Added tests for stale-anchor recovery flows and FileReadCache session, null, overlap, and eviction behavior.
- Expanded read tool range calculations to include optional leading and trailing context lines around user-requested offsets and limits.
- Added shared context range expansion logic so line-slice and streaming reads return anchor-safe windows while preserving existing truncation behavior.
- Updated read-tool tests to assert boundary-offset, limit, and combined offset-limit reads now include the expected ±3 lines of context.
- Added a Python `analyze.py` CLI with `tools`, `edits`, and `followups` session-stats subcommands.
- Added `sync.py` ingestion with `~/.omp/stats.db`, migration SQL, and incremental JSONL resume logic.
- Replaced `stats:run` in `package.json` with `stats:sync` and new `stats:edits`, `stats:tools`, and `stats:followups` scripts.
- Removed the Rust session-stats crate files (`Cargo.toml`, `main.rs`, `common.rs`, `cmd_*.rs`) and their old command logic.
- Removed `.gitignore` ignores for `scripts/session-stats/Cargo.lock` and `scripts/session-stats/edit-analysis.csv`.
- Updated eval tool guidance to show Python `asyncio.run(...)` usage.
Some extensions/plugins still import the legacy @mariozechner/pi-* package names (pi-agent-core, pi-ai, pi-coding-agent, pi-tui) instead of @oh-my-pi/pi-*. Register a single Bun.plugin on first plugin/extension load that rewrites those specifiers to the current @oh-my-pi/pi-* equivalents, including the @mariozechner/pi-coding-agent/extensibility/{extensions,hooks} sub-exports. No filesystem mutation, no symlinks, no proxy files.
Fixes#973
Add an explicit openai-models-list discovery type for custom providers while keeping lm-studio as a compatible alias. Custom providers can now point baseUrl at an OpenAI-compatible /v1 endpoint, provide an api key, and auto-populate models via GET {baseUrl}/models.
Discovered models merge cleanly with user-defined models from models.yml/models.json, so YAML entries still win for display name and token limits. The provider picker now explains when discovery succeeds but returns zero models, and when the configured /models endpoint responds with 404.
Fixes#970
Interactive /mcp test only consulted getMCPConfigPath("user"|"project")
configs and missed servers defined in standalone .mcp.json. /mcp reauth
already resolved through #findConfiguredServer, which includes that
fallback path. Route /mcp test through the same resolver so both
commands enumerate the same set of servers.
Fixes#956
The custom status line rendered cache_read with the input icon and
cache_write with the output icon — backwards relative to Anthropic's
cache_creation_input_tokens (write) / cache_read_input_tokens (read)
semantics. Swap the icon pairings in status-line/segments.ts and the
labels in status-line-segment-editor.ts to match.
Fixes#953
runSplitCommit reset the index and then re-staged each split via
git.stage.hunks, but stage.hunks builds its file map from the current
diff. After the reset, newly created files were untracked again and
absent from that map, throwing "No diff found for <path>" mid-split.
Preserve the original staged diff so new files remain locatable
through every split iteration.
Fixes#966
- BuildWorkspaceTree now attempts to list files via `git ls-files` and builds a child index for tree rendering, avoiding native recursion when git output is available.
- `buildDirectoryTree` gained an optional `childIndex` path map, `tryListGitFiles` now applies a 3s timeout and falls back to existing native scan on failure or timeout.
- Added a workspace-tree test that verifies git-backed listing skips gitignored entries while including tracked workspace files.
- Added a static-import rewriter that converts common import clauses into dynamic `await import(...)` expressions before VM wrapping.
- Provided `require` and `createRequire` globals in the JS VM context using a cwd-based resolver.
- Added executor tests confirming rewritten imports run correctly and that `require`/`createRequire` are exposed with expected behavior.
- Added optional `/loop` `count|duration` command arguments and wired `command.args` into loop handling.
- Implemented `loop-limit` parsing and runtime types/helpers for iteration and duration budget limits with validation.
- Updated interactive mode to enforce loop limits per iteration, check duration expiry, and clear budget state on disable.
- Added loop-limit parse/runtime tests and fixed `/loop` arg errors plus macOS `MallocStackLogging` environment leakage.
- Rendered diff content before the truncation notice instead of after.
- Updated hidden lines label to show count with "+" prefix.
- Added fallback label when no lines are hidden.
- Exported hashline section interfaces and helpers, including a new section-diff API for external callers.
- Refactored `computeHashlineDiff` to split input sections, propagate split errors, and delegate each section via helper.
- Added context-highlight caching and batched highlighting for unchanged lines, with `replaceTabs` fallback on unknown files.
- Fixed hashline streaming preview so completed sections stay visible when a new `@PATH` header appears mid-stream.
- Added hashline streaming tests for section persistence, malformed trailing `+ 7`, and dual sections.
- Added `.ipynb` detection and editable-cell conversion utilities, including merge/serialize helpers in `edit/notebook`.
- Rerouted hashline, patch, and replace edit flows, plus read/write paths, through notebook-aware helpers before persistence.
- Removed the dedicated `notebook` tool, its schema flags, renderer, and built-in registration/settings checks.
- Updated notebook read behavior, docs, and tests so `.ipynb` reads return editable `# %%` cells and edits reserialize to JSON.
