- Added tiny-title protocol contracts, including progress-state unions, message payloads, and transport interfaces.
- Added title text utilities to truncate long inputs, wrap `<user-message>` blocks, and normalize generated titles.
- Added tiny-title model registry and helpers with type-safe keys and runtime optional loading via optionalDependencies.
- Added client-side worker orchestration with spawn fallback, request queueing, progress/error routing, and smoke-test APIs.
- Added worker runtime for model resolution, prompt-based inference, lock-based install retries, and close-time cache clear.
- Added `providers.tinyModel` with an `online` default and UI schema metadata; documented tiny-title updates in changelogs.
- Added tiny-title system prompt and title-text helpers to truncate input, wrap `<user-message>`, and normalize output.
- Added tiny-title model registry, local model specs, key validation, and cache-path helper.
- Added tiny-title transport/client/worker flow with spawn fallback, queued requests, ping checks, and graceful close.
- Updated `generateSessionTitle` to route by tiny-title model and race local generation against delayed online fallback.
- Updated OpenAI completions parameterization to honor `disableReasoning` on effort-based compatible models by sending the minimum supported effort.
- Expanded commit and title generation token budgets so reasoning models can return output after internal thinking while non-reasoning calls keep existing limits.
- Switched title generation to request a `set_title` tool call, added extraction from tool-call arguments, and updated tests for the new behavior.
- Skipped thinking-line writes and clears when stdout is not a TTY.
- Prevented terminal title (set/push/pop) from emitting OSC/xterm escape sequences to piped or non-interactive output.
- Suppressed all ProcessTerminal control writes when stdout isn't a TTY.
Anthropic counts sessions by metadata.user_id. Without this fix, OMP
generated fresh random entropy on every API request, inflating the
session count and preventing backend attribution to the authenticated
account.
Changes:
packages/ai:
- resolveAnthropicMetadataUserId() now accepts JSON-format user_id
matching real Claude Code's getAPIMetadata shape
({ session_id, account_uuid, ... }). Previously only the legacy
cloaking format was accepted on OAuth, causing stable caller-supplied
values to be silently discarded.
- AnthropicOAuthFlow.exchangeToken() and refreshAnthropicToken() now
populate OAuthCredentials.{accountId, email} from the token response
account block, removing the need for a separate /api/oauth/profile
round-trip.
- AuthStorage.getOAuthAccountId(provider, sessionId) returns the OAuth
accountId for the session-sticky credential, used to build
account_uuid in metadata.user_id. Guards against misattribution for
API-key, runtime-override, env-key, and fallback-resolver paths that
do not record a session credential.
packages/agent:
- Agent.metadataForProvider(provider) resolves request metadata for
the given provider via the installed resolver, or returns the static
metadata value. The plain metadata getter now returns only the static
value; provider-aware resolution is explicit.
- Agent.setMetadataResolver(fn) installs a (provider: string) resolver
evaluated per LLM request in agent-loop, after getApiKey records the
session-sticky credential, so account_uuid reflects the credential
actually used.
- AgentLoopConfig.metadataResolver is called with config.model.provider
after getApiKey, overriding the static metadata field.
packages/coding-agent:
- AgentSession.#syncAgentSessionId installs a metadata resolver that
builds { user_id: JSON.stringify({ session_id, account_uuid? }) },
matching the Anthropic session attribution format. account_uuid is
only included for provider="anthropic" to avoid leaking the OAuth
identity to third-party Anthropic-format-compatible providers.
- sessionId getter prefers providerSessionId when supplied via
AgentSessionConfig so all API paths (getApiKey, direct calls,
metadata resolver) share the same provider-facing session ID.
- prepareSimpleStreamOptions stamps session metadata on direct calls
(runEphemeralTurn, compaction, branch summary, title generation) so
they share the same session bucket as Agent.prompt requests.
- generateBranchSummary and generateSessionTitle accept a
(provider: string) metadata resolver evaluated after their own
getApiKey call for correct credential attribution.
- Converted systemPrompt APIs and state types to ordered `string[]` across agent, AI, and coding-agent surfaces.
- Added `normalizeSystemPrompts` and applied it to context normalization before building provider request payloads.
- Updated AI providers to emit separate normalized prompt blocks/messages instead of a single merged system prompt.
- Removed dedicated `projectPrompt` state and remapped that context into system-context buckets in session, dump, and token accounting.
- Aligned tests and changelogs to pass and assert `systemPrompt` as arrays with ordered prompt semantics.
- Added `disableReasoning` to `SimpleStreamOptions` and OpenAI completions, sending `reasoning: { enabled: false }` for OpenRouter requests to prevent reasoning models from consuming the full output budget on small calls like title generation.
- Fixed `canAppend` to accept `response.completed` as a terminal event, restoring websocket append reuse after codex sessions end.
- Replaced async blob-decoding and `addEventListener` with synchronous `onmessage`/`onopen`/`onerror`/`onclose` handlers and `binaryType = "nodebuffer"` for simpler, reliable message decoding.
- Simplified title generator to discard per-role thinking level and always pass `disableReasoning: true`.
- Removed title-source aware branching from session terminal-title and accent helpers, and updated callers to use session name plus cwd only.
- Dropped UUID-based recent-session naming by preferring explicit header titles or first user prompts and generating an "Untitled · <time>" fallback.
- Adjusted welcome session-row rendering for width-aware name truncation and disabled reasoning in title generation requests to keep terminal titles concise.
- Propagated session title source through terminal-title update calls so auto and user names are handled consistently across controllers.
- Suppressed auto-generated names in status-line segments and completion messages by falling back to cwd-based titles.
- Updated title formatter tests to verify auto-generated and user-specified session titles produce different terminal labels.
- Add /rename <title> slash command to set an explicit session name,
updating the session header, terminal tab title, and status line
- Add session_name status segment: displays the session name on the
right side of the status bar with a stable djb2-hash-derived accent
color unique to each name; shown in all presets when a name is set
- Add setSessionName source tracking ('user' vs 'auto'): auto-generated
titles are silently ignored once the user has explicitly set a name,
preventing the async title generation from overwriting a /rename
- Sanitize session names at storage time: strip C0/C1 control characters
(including ANSI ESC) via static #sanitizeName before storing, blocking
escape sequence injection into the TUI, terminal title, and session file
- Extend sanitizeStatusText to cover the full C0/C1 range as
defense-in-depth (superset of the previous \r\n\t-only strip)
- Use stored (sanitized) name for showStatus message and terminal title
in handleRenameCommand, not the raw user input
- Guard terminal title update in auto-title path via titleSource === 'auto'
so a user rename is never overwritten by a late-resolving LLM call
- Reset #titleSource in #newSessionSync so each new session starts fresh
- Thread source parameter through AgentSession.setSessionName wrapper;
extension API and RPC set_session_name treated as 'user' intent
Closes#658
- Added canonical model equivalence types, cache helpers, and registry APIs for provider variant lookup.
- Changed model resolution to apply canonical ID overrides/excludes with provider order before fallback matching.
- Added canonical and provider model views in list-models and selector UI with canonical sorting/persistence.
- Updated role/model persistence to store selectors while runtime now resolves concrete canonical-backed provider models.
- Extracted prompt rendering and formatting utilities from coding-agent to centralized pi-utils package with new API surface (prompt.render, prompt.format, prompt.registerHelper).
- Migrated parseFrontmatter utility from coding-agent to pi-utils package; updated 8 files to import from @oh-my-pi/pi-utils.
- Removed 170-line prompt-format.ts module and consolidated 192 lines of Handlebars helper registrations into pi-utils prompt module.
- Updated 60+ files across coding-agent and typescript-edit-benchmark to use new prompt.render() and prompt.format() API from pi-utils.
- Simplified prompt-templates.ts by delegating core functionality to pi-utils while retaining custom helper registrations (jtdToTypeScript, jsonStringify, etc.).
- Added automatic deduplication of identical context files by content, keeping the closest (lowest depth) copy when duplicates are discovered.
- Implemented dedupeExactContextFiles() function to filter duplicate context entries in both explicit and discovered file lists.

- Improved prompt formatting with consistent newlines and whitespace in agent configuration files.
- Replaced ASCII ellipsis characters (three dots '...') with Unicode ellipsis character ('...') throughout the codebase for improved typography.
- Adjusted string truncation logic to account for single-character Unicode ellipsis instead of three-character ASCII ellipsis, reducing reserved space from 3 to 1 character in truncation calculations.
- Updated truncation offsets in multiple files (session-manager, agent, executor, footer) to preserve 2 additional characters before ellipsis due to more compact Unicode representation.
- Removed Prettier configuration files (.prettierignore and .prettierrc) and migrated formatting to Biome.
- Updated Biome configuration from version 2.3.11 to 2.3.12 and changed arrowParentheses rule from 'always' to 'asNeeded'.
