Reduce the race where killing a foreground child wakes its shell before the shell is signalled. Keep Linux and Windows termination unchanged and preserve kill fallbacks when stopping fails.

Use authoritative OpenRouter billing for Chat Completions and Anthropic Messages while retaining catalog component estimates and fallback behavior.
Fixes#9980
Add Usage.cost.totalFromProvider to record whether cost.total is the
billed cost reported by the provider or an estimate from catalog rates.
Catalog-derived totals set it to false; a missing value also means
false. combineUsage marks a sum as provider-reported only when both
parts are.
Jev (TypeSafe, Workers AI), Clef (Workers AI), and OpenRouter decision
models now accept ClassifierContext.images. Each service takes its own
wire form: TypeSafe assets with the opt-in header, Clef images data URLs,
or OpenRouter image_url parts in the state. A new SystemOneCompat
(imageInput, sendImageOptInHeader) selects the form; catalog entries set
it explicitly and models.json provider compat now applies to classifiers.
Adds Clef Omni and Jev 1.14 on Workers AI and fixes Clef Flash and
Workers AI Jev catalog pricing.
Pre-prompt recovery of a recoverable length stop omitted the assistant
message but not the tool results that answered its calls, because only
the end-of-run caller passed them. The orphaned results were persisted
and providers rejected every later request.
_omitRecoveryAttempt now finds the matching tool results in the
projected context itself, so every caller omits the pair together.
closes#11227
The built-in grep tool spawned rg with the inherited environment, so
RIPGREP_CONFIG_PATH (e.g. a config containing --fixed-strings) silently
changed tool semantics: literal: false searches became literal and the
agent got incomplete results with no error.
Pass --no-config so the tool contract is deterministic. Users who want
custom rg behavior can use the bash tool or wrap grep in an extension.
closes#11203
Resume and /tree restored exactly the tools the branch recorded, so extension
tools registered later stayed inactive. Registered extension tools that the
branch never added or removed are now activated unless they use
defaultActive: false. The whole branch is searched, so tools removed before a
compaction stay inactive. Also fixes the /tree case from #11075.
closes#11062
- ClientAttribution is { name, url, categories? } with required name and url, so
OpenRouter always gets an HTTP-Referer. identity.ts maps the fields to each
provider's headers; NVIDIA gets the name with its first letter upper-cased.
attribution: null turns it off. PI_ATTRIBUTION is pi's, including the
cli-agent category; agent-core, durable, and the coding agent use it.
- Categories are a string array, joined for OpenRouter.
- withClientIdentity() is a typed wrapper instead of a Proxy and keeps a
MutableModels mutable. Durable no longer caches wrappers in a WeakMap.
- The Codex originator stays pi; login agentName no longer follows attribution.
- Models and the coding agent's ModelRuntime add x-opencode-session for custom
providers pointing at OpenCode, replacing the coding agent's transformHeaders.
pi-ai gets a ClientIdentity request option and createModels() default that choose the User-Agent (detailed with version, short, or custom) and provider attribution headers for OpenRouter, NVIDIA NIM, and OpenCode. Attribution is off by default in pi-ai and on by default in pi-agent-core and pi-durable (HarnessOptions.identity). pi-coding-agent sets its identity from the telemetry setting instead of adding headers itself.
Extensions importing the public /models subpath (e.g. clampThinkingLevel)
failed with "Cannot find module" because the loader aliased/virtualized
only the pi-ai root, /compat, /oauth, and /providers/all entrypoints.
Add /models to the jiti aliases and the embedded virtual module map,
plus a regression test importing it without a local pi-ai install.

Scripts wait in arrival order for a free worker instead of failing
immediately. The wait counts toward timeout_ms, honours abort, and is
capped at 60 seconds. PI_CODEMODE_MAX_WORKERS raises the process-wide
limit of two workers for hosts running many sessions in one process.
closes#11184
A second select/confirm/input/editor dialog or inline custom() component
replaced the visible one and left its promise pending forever. Dialogs in
the editor slot now form a stack: closing the visible dialog shows the
previous one again, and dialogs opened from inside a custom component work.
closes#11166
The openai-codex provider authenticates with a ChatGPT account, and the
Codex backend rejects gpt-5.5 and gpt-5.3-codex-spark for those accounts
("not supported when using Codex with a ChatGPT account"). Remove them
from the catalog so model pickers stop offering models that always fail.
Codex e2e tests that used openai-codex/gpt-5.5 now use gpt-6.1-sol, the
openai-codex default. The context overflow test uses gpt-5.6-sol to keep
its prompt smaller.

Windows PowerShell 5.1 adds a BOM when it rewrites managed-install.json, which made pi update fail with "Managed install marker is missing or invalid".
Copilot rejects request bodies over its byte-size limit with HTTP 413 and a generic
'failed to parse request' body, so the existing token-count heuristics never matched.
Treat any HTTP 413 as request-size overflow regardless of provider or body text, so
the agent compacts and retries instead of surfacing a raw API error.
Validated against the live Copilot API (40MB image payload): main classifies the 413
as a plain error, this branch detects it as overflow.
Node's existsSync() can reject runnable Store aliases because its extra
Windows-only stat check fails with EACCES (nodejs/node#36790). Use
access(F_OK) for shell validation on all platforms instead, matching the
check harness-v2's async refactor settled on (617d8b317, now pathExists
in packages/durable/src/env/node.ts). On Unix this is a no-op: existsSync
is already access(F_OK) there, so shell search order and behavior stay
unchanged; on Windows runnable aliases now pass validation.
* docs(ai,coding-agent): generate models.json reference from schemas
Add npm run generate:references, which renders docs/models-configuration.md
from the models.json TypeBox schemas, and describe provider and model fields
in those schemas. Overrides get their own descriptions without defaults, and
compat sections cover the Responses API aliases.
closes#10790
* Modify changelog
* docs(ai,coding-agent): use shared thinkingLevelMap and promptCache schemas
Replace the per-use schema helpers with fixed schemas whose descriptions
hold for both models and modelOverrides entries.
Compaction summaries were limited to 0.8 * compaction.reserveTokens (13107 by default), turn-prefix summaries to 0.5 * reserveTokens, and branch summaries to a hardcoded 4096. On providers where reasoning shares the output limit (OpenAI Responses, adaptive Anthropic), high thinking levels used most of that limit and compaction failed with "generation hit the token cap", even though the model allows far more output.
Tying the limit to reserveTokens assumed the summary request is as large as the full context, so its output had to fit in the reserved space. It is usually much smaller: recent messages kept by keepRecentTokens are not sent, a split turn goes to a separate request, tool results are truncated, and tool definitions and the normal system prompt are not included. Manual compaction can also run long before the context is full. The provider layer already sizes output from the actual request, using the model's output limit reduced to fit the remaining context, as for normal turns.
Summary requests now set no maxTokens and rely on that. compaction.reserveTokens only controls when compaction starts.
generateSummary() and generateSummaryWithUsage() now ignore the reserveTokens parameter.

done() from ctx.ui.custom({ overlay: true }) closed the overlay with
ui.hideOverlay(), which removes the topmost overlay instead of the one
that called done(). With a shell overlay open under a dialog overlay
from another extension, the shell's exit removed the dialog: the
finished shell overlay stayed on screen ignoring input and the dialog's
promise never resolved. Hide the overlay through its own handle.
closes#10648
* fix(coding-agent): resolve model references through one provider selection policy
Model references from --model, --models/enabledModels, /model, and auth credential printing now share one resolver. It collects every candidate before choosing a provider, so catalog order never decides, a :<thinking> suffix cannot change the provider, and an ambiguous exact match no longer falls through to a fuzzy match.
provider/id still prefers the named provider's exact or fuzzy match. A gateway exposing provider/id as a raw model id is used when the named provider has no match, or lacks credentials while the gateway has them. Several gateways without a unique authenticated one are reported as ambiguous.

The SDK always passed initial tools, so the constructor never restored the
loadout recorded in the transcript, and resumed sessions dropped tools activated
during the session. Sessions that use the default tools now restore the recorded
loadout, with --tools +name/-name entries applied to it.

A misplaced options line was ignored, so its timeout_ms never applied and

CodemodeSourceError before the script runs.

A just-removed auth.json.lock directory can stay delete-pending on Windows
while another process holds a handle, making mkdir fail with EPERM. Retry
this briefly (capped separately from ELOCKED) so real permission errors
still fail fast.

Print mode now writes a warning to stderr and exits 1 when the final
response stopped at the model's output token limit. The partial text
is still written to stdout.

The codemode row shows "Elapsed" while the script runs and "Took" once
it finishes, like bash rows. The timer logic moves from the bash renderer
to render-utils, and scripts send an initial update so the timer starts
before the first nested call.

MCP 2026-07-28 allows structuredContent to be any JSON value, including
arrays and null. callTool() rejected non-object values, failing the whole
tool call. CallToolResult.structuredContent is now unknown, and MCP tools
without an output schema declare structuredContent as unknown to codemode.

Servers with resources registered no tools until resources/list and
resources/templates/list finished, so a slow listing (a large drive)
kept their tools out of the first prompt. The lists only fed counts in
/mcp and pi mcp list; both now show that a server offers resources.
The resource tools still list and read resources on demand.

Entries like !~/skills/pdf, +~/x and -~/x in the extensions, skills,

Deletes packages/client, packages/protocol (CBOR codec), packages/server, coding-agent's
src/experimental (except source-resolver.ts, which source runs still preload), src/cli/experimental,
src/client, the example plugin, and their tests. coding-agent no longer depends on @earendil-works/chord.
The installer lock drops esbuild, so its platform-package sanity check goes too.
On each OpenRouter refresh, combine the catalog (built-in models plus a newer pi.dev catalog) with GET /models/user for the user's key: keep only the listed chat models and take their context size, max output and prices from it. Image and classifier models are kept. The combined list is saved and replaces the OpenRouter catalog, including offline.
- ai: add personalizeOpenRouterCatalog and RefreshModelsContext.baseUrl, so the request follows a base URL configured in models.json (regional endpoints)
- ai: share OpenRouter price conversion with the generator; negative prices (router models such as openrouter/auto) become 0
- coding-agent: add withPersonalizedCatalog next to withRemoteCatalog
- docs: OpenRouter section in providers.md

joinAdjacentText checked endsWith on the growing joined string, which

Runs started by pi.sendMessage(..., { triggerTurn: true }) skipped before_agent_start. After their first tool call, the next-turn refresh fell back to the base prompt options and patched away the sections handlers had added, changing the system prompt mid-run and breaking the provider prompt cache.
These runs now go through the same setup as prompt(): compaction check, before_agent_start, tool loadout, nextTurn messages, handler messages, and the system patch. BeforeAgentStartEvent is a union on messageType ("user" or "custom"); custom events carry the starting message.
The session counts as busy from the start of setup, so messages sent while handlers run go into the starting run instead of starting a second one, and an abort requested meanwhile aborts the run once it starts.

partly fixes#10606
Tools that reach other tools declare it with reachesTools(input); MCP uses it to wait for the servers a call needs and to decide which codemode or tool_search tool to activate, instead of parsing codemode scripts and comparing parameter schemas. Namespaces get aliases, replacing codemode's MCP-specific __ suffix rule.
pi-codemode no longer knows MCP: MCP_TYPESCRIPT_PREAMBLE and mcpStructuredContentSchema() are removed, and the MCP result schema describes itself, with the server's local $refs relocated so they resolve as before.
Replayed thinking is often not part of the live context (for example,
radius drops it, and Anthropic drops blocks that do not match their
request), but serializeConversation included all of it. A Pi Mobile
session at ~996K of 1M context tokens produced 1.38M-token summarization
requests that failed on every attempt. Providers only return summaries of
the reasoning anyway; visible text, tool calls, and tool results record
what happened.

The nested worktree dedup compared the context file's realpath with the
