From 505f2e95c163f4970898a5ababe18a0f6ea8967e Mon Sep 17 00:00:00 2001 From: Daniele Date: Sun, 23 Aug 2026 20:53:30 +0100 Subject: [PATCH] =?UTF-8?q?feat(chat):=20view=20context=20=E2=80=94=20tell?= =?UTF-8?q?=20the=20assistant=20what=20you're=20looking=20at?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit An eye next to the paperclip shares what the user has open with their next message: the page, the folder being browsed, the file open in the viewer and any highlighted passage (line numbers where a source view exists), plus which entity a detail page is about. The bag is client-authored {label, value} pairs in English — the backend only clamps (chars, never bytes), neutralizes the harness tag and renders one block per message, deduped consecutively so it appears exactly when the view changed. On by default, per-device toggle, hover/tap to preview, a chip on every sent message; docs/view-context.md for users, an updated harness.md clause for the model. --- CHANGELOG.md | 16 + agents/common/harness.md | 9 +- crates/agent-loop/src/context.rs | 9 +- crates/agent-loop/src/projection/mod.rs | 89 +++- crates/agent-loop/tests/projection.rs | 122 ++++- crates/core-api/src/events.rs | 12 +- crates/core-api/src/message_meta.rs | 415 ++++++++++++++++-- .../src/loop_adapters/media_source.rs | 211 ++++++++- .../src/loop_adapters/projection_cfg.rs | 11 +- .../skald-core/src/loop_adapters/translate.rs | 8 +- docs/index.md | 3 +- docs/view-context.md | 31 ++ src/frontend/api/sessions.rs | 14 +- src/frontend/api/ws.rs | 11 +- web/app.js | 3 + web/components/connector-detail.js | 24 +- web/components/copilot-render.js | 99 ++++- web/components/copilot.js | 14 +- web/components/llm-requests.js | 20 + web/components/marketplace.js | 17 +- web/components/mobile-app.js | 18 + web/components/models-hub.js | 18 + web/components/plugin-detail.js | 11 +- web/components/plugin-page-host.js | 28 +- web/components/projects/project-board.js | 28 +- web/components/session-detail.js | 12 +- web/components/shared/chat-page.js | 3 +- web/components/shared/file-explorer.js | 30 ++ web/components/shared/file-viewer-base.js | 175 ++++++++ web/components/sidebar.js | 20 +- web/components/system-agents.js | 18 +- web/components/tasks/index.js | 18 + web/components/tool-detail-page.js | 18 +- web/components/users-page.js | 20 + web/css/copilot-messages.css | 138 ++++++ web/i18n/en.js | 10 + web/i18n/fr.js | 7 + web/i18n/it.js | 7 + web/lib/chat-session.js | 75 +++- web/lib/routes.js | 42 ++ web/lib/view-context-routes.js | 213 +++++++++ web/lib/view-context.js | 171 ++++++++ 42 files changed, 2096 insertions(+), 122 deletions(-) create mode 100644 docs/view-context.md create mode 100644 web/lib/routes.js create mode 100644 web/lib/view-context-routes.js create mode 100644 web/lib/view-context.js diff --git a/CHANGELOG.md b/CHANGELOG.md index 7dabf76..86e072e 100644 --- a/CHANGELOG.md +++ b/CHANGELOG.md @@ -16,6 +16,20 @@ release PR may merge — and a section is closed at the commit that bumps it. or delete wherever you have write access; the read-only places say so.
