### New Features
- Prompt templates support an `argument-hint` frontmatter field that renders before the description in the `/` autocomplete dropdown, using `<angle>` for required and `[square]` for optional arguments. See [docs/prompt-templates.md#argument-hints](docs/prompt-templates.md#argument-hints).
- New `after_provider_response` extension hook lets extensions inspect provider HTTP status codes and headers immediately after each response is received and before stream consumption begins. See [docs/extensions.md](docs/extensions.md).
- Compact interactive startup header with a comma-separated view of loaded AGENTS.md files, prompt templates, skills, and extensions. Press `Ctrl+O` to toggle the expanded listing.
- Markdown links in assistant output now render as OSC 8 hyperlinks on terminals that advertise support; unknown terminals and tmux/screen default to plain text so URLs are never silently dropped.
### Added
- Added `argument-hint` frontmatter field for prompt templates, displayed before the description in the autocomplete dropdown ([#2780](https://github.com/badlogic/pi-mono/pull/2780) by [@andresvi94](https://github.com/andresvi94))
- Added `after_provider_response` extension hook so extensions can inspect provider HTTP status codes and headers after each provider response is received and before stream consumption begins ([#3128](https://github.com/badlogic/pi-mono/issues/3128))
- Added OSC 8 hyperlink rendering for markdown links when the terminal advertises support ([#3248](https://github.com/badlogic/pi-mono/pull/3248) by [@ofa1](https://github.com/ofa1))
### Changed
- Changed interactive startup header to a compact, comma-separated view of loaded AGENTS.md files, prompt templates, skills, and extensions, with `Ctrl+O` to toggle the expanded listing ([#3267](https://github.com/badlogic/pi-mono/pull/3267))
- Tightened hyperlink capability detection to default `hyperlinks: false` for unknown terminals and force it off under tmux/screen (including nested sessions), preventing markdown link URLs from disappearing on terminals that silently swallow OSC 8 sequences ([#3248](https://github.com/badlogic/pi-mono/pull/3248))
### Fixed
- Fixed `--verbose` startup output to begin with expanded startup help and loaded resource listings after the compact startup header change ([#3147](https://github.com/badlogic/pi-mono/issues/3147))
- Fixed `find` tool returning no results for path-based glob patterns such as `src/**/*.spec.ts` or `some/parent/child/**` by switching fd into full-path mode and normalizing the pattern when it contains a `/` ([#3302](https://github.com/badlogic/pi-mono/issues/3302))
- Fixed `find` tool applying nested `.gitignore` rules across sibling directories (e.g. rules from `a/.gitignore` hiding matching files under `b/`) by dropping the manual `--ignore-file` collection and delegating to fd's hierarchical `.gitignore` handling via `--no-require-git` ([#3303](https://github.com/badlogic/pi-mono/issues/3303))
- Fixed OpenAI Responses prompt caching for non-`api.openai.com` base URLs (OpenAI-compatible proxies such as litellm, theclawbay) by sending the `session_id` and `x-client-request-id` cache-affinity headers unconditionally when a `sessionId` is provided, matching the official Codex CLI behavior ([#3264](https://github.com/badlogic/pi-mono/pull/3264) by [@vegarsti](https://github.com/vegarsti))
- Fixed the `preset` example extension to snapshot the active model, thinking level, and tool set on the first preset application and restore that state when cycling back to `(none)`, instead of falling back to a hardcoded default tool list ([#3272](https://github.com/badlogic/pi-mono/pull/3272) by [@stembi](https://github.com/stembi))
