a third-party bot is attributed by name rather than mislabeled as the assistant. - both adapters: use the generic [media] reference for ANY reply that has no usable text, so a reply to a poll/location (not just an enumerated media type) keeps its anchor; drops the now-redundant replyHasMedia enumeration. - chat: rune-count before allocating on the truncation path (no []rune slice for the common short quote). - tests: cover the msg.Quote highest-preference branch, a media-only reply and a media-only forward, and the third-party-bot author label. --- adapters/vk/receiver_test.go | 26 ++++++ cmd/flock-telegram/main.go | 29 ++---- cmd/flock-telegram/quoted_context_test.go | 104 +++++++++++++++++++++- core/chat/media.go | 7 +- 4 files changed, 143 insertions(+), 23 deletions(-) diff --git a/adapters/vk/receiver_test.go b/adapters/vk/receiver_test.go index c4ee599..c59421f 100644 --- a/adapters/vk/receiver_test.go +++ b/adapters/vk/receiver_test.go @@ -261,6 +261,32 @@ func TestReceiverNoReplyPromptUnchanged(t *testing.T) { } } +// TestReceiverFoldsMediaOnlyForward: a forwarded message that carries only an +// attachment (no text) yields the generic [media] reference, the same as a media-only +// reply — so the forwarded reference is never silently dropped. +func TestReceiverFoldsMediaOnlyForward(t *testing.T) { + svc := &fakeService{} + r := newTestReceiver(svc, &fakeNotice{}, false, nil) + + r.dispatch(context.Background(), msgNewUpdate(t, messageObject{ + FromID: 42, PeerID: 200, Text: "смотри", ConversationMessageID: 14, + FwdMessages: []messageObject{ + {FromID: 42, Attachments: []attachment{{Type: "doc", Doc: &docAttachment{}}}}, + }, + })) + + if len(svc.handleCalls) != 1 { + t.Fatalf("Handle calls = %d, want 1", len(svc.handleCalls)) + } + got := svc.handleCalls[0].prompt + if !strings.Contains(got, "[media]") { + t.Errorf("prompt %q missing the [media] placeholder for a media-only forward", got) + } + if !strings.Contains(got, "смотри") { + t.Errorf("prompt %q missing the user's new text", got) + } +} + func TestReceiverIgnoresDisallowedAndCommunityMessages(t *testing.T) { svc := &fakeService{} r := newTestReceiver(svc, &fakeNotice{}, false, nil) diff --git a/cmd/flock-telegram/main.go b/cmd/flock-telegram/main.go index ee079c6..f762437 100644 --- a/cmd/flock-telegram/main.go +++ b/cmd/flock-telegram/main.go @@ -746,7 +746,7 @@ const assistantAuthorLabel = "the assistant" // message is not a reply/quote, which keeps a normal message byte-for-byte // unchanged.
