# Comments Feature Implementation Plan
2
+
3
+
> **For Claude:** REQUIRED SUB-SKILL: Use superpowers:executing-plans to implement this plan task-by-task.
4
+
5
+
**Goal:** Add Instagram-style bottom sheet for viewing and posting comments on galleries.
6
+
7
+
**Architecture:** Bottom sheet component opens when comment icon is tapped, shows paginated comment list with threaded replies (single indent level), and a fixed input bar at bottom with user avatar and send button. Login required to view comments.
8
+
9
+
**Tech Stack:** Lit 3, Web Components, GraphQL (quickslice), CSS custom properties

## Task 1: Add createComment to mutations service
14
+
15
+
**Files:**
16
+
- Modify: `src/services/mutations.js`
17
+
18
+
**Step 1: Add createComment method**
19
+
20
+
Add after the `toggleFollow` method in `src/services/mutations.js`:
21
+
22
+
```javascript
23
+
async createComment(galleryUri, text, replyToUri = null) {
24
+
const client = auth.getClient();
25
+
const input = {
26
+
subject: galleryUri,
27
+
text,
28
+
createdAt: new Date().toISOString()
29
+
};
30
+
31
+
if (replyToUri) {
32
+
input.replyTo = replyToUri;
33
+
}
34
+
35
+
const result = await client.mutate(`
36
+
mutation CreateComment($input: SocialGrainCommentInput!) {
37
+
createSocialGrainComment(input: $input) { uri }
38
+
}
39
+
`, { input });
40
+
41
+
return result.createSocialGrainComment.uri;
42
+
}
43
+
```
44
+
45
+
**Step 2: Verify the file saves correctly**
46
+
47
+
Run: `head -20 src/services/mutations.js`
48
+
49
+
**Step 3: Commit**
50
+
51
+
```bash
52
+
git add src/services/mutations.js
53
+
git commit -m "feat: add createComment mutation"
54
+
```

## Task 2: Add getComments method to grain-api service
59
+
60
+
**Files:**
61
+
- Modify: `src/services/grain-api.js`
62
+
63
+
**Step 1: Add getComments method**
64
+
65
+
Add before the closing brace of the class in `src/services/grain-api.js`:
66
+
67
+
```javascript
68
+
async getComments(galleryUri, { first = 20, after = null } = {}) {
69
+
const query = `
70
+
query GetComments($galleryUri: String!, $first: Int, $after: String) {
71
+
socialGrainComment(
72
+
first: $first
73
+
after: $after
74
+
where: { subject: { eq: $galleryUri } }
75
+
sortBy: [{ field: createdAt, direction: ASC }]
76
+
) {
77
+
edges {
78
+
node {
79
+
uri
80
+
text
81
+
createdAt
82
+
actorHandle
83
+
replyTo
84
+
socialGrainActorProfileByDid {
85
+
displayName
86
+
avatar { url(preset: "avatar") }
87
+
}
88
+
}
89
+
}
90
+
pageInfo {
91
+
hasNextPage
92
+
endCursor
93
+
}
94
+
totalCount
95
+
}
96
+
}
97
+
`;
98
+
99
+
const response = await this.#execute(query, { galleryUri, first, after });
100
+
const connection = response.data?.socialGrainComment;
101
+
102
+
if (!connection) {
103
+
return { comments: [], pageInfo: { hasNextPage: false, endCursor: null }, totalCount: 0 };
104
+
}
105
+
106
+
const comments = connection.edges.map(edge => {
107
+
const node = edge.node;
108
+
const profile = node.socialGrainActorProfileByDid;
109
+
return {
110
+
uri: node.uri,
111
+
text: node.text,
112
+
createdAt: node.createdAt,
113
+
handle: node.actorHandle,
114

displayName: profile?.displayName || '',
115
+
avatarUrl: profile?.avatar?.url || '',
116
+
replyToUri: node.replyTo || null
117
+
};
118
+
});
119
+
120
+
return {
121
+
comments,
122
+
pageInfo: connection.pageInfo || { hasNextPage: false, endCursor: null },
123
+
totalCount: connection.totalCount || 0
124
+
};
125
+
}
126
+
```
127
+
128
+
**Step 2: Commit**
129
+
130
+
```bash
131
+
git add src/services/grain-api.js
132
+
git commit -m "feat: add getComments query to grain-api"

## Task 6: Make comment icon interactive in engagement bar
812
+
813
+
**Files:**
814
+
- Modify: `src/components/organisms/grain-engagement-bar.js`
815
+
816
+
**Step 1: Add galleryUri prop if not already present, and emit comment-click event**
817
+
818
+
The component already has `galleryUri` prop. Add click handler to comment stat:
819
+
820
+
Find this block:
821
+
```javascript
822
+
<grain-stat-count
823
+
icon="comment"
824
+
count=${this.commentCount}
825
+
></grain-stat-count>
826
+
```
827
+
828
+
Replace with:
829
+
```javascript
830
+
<grain-stat-count
831
+
icon="comment"
832
+
count=${this.commentCount}
833
+
?interactive=${true}
834
+
@stat-click=${this.#handleCommentClick}
835
+
></grain-stat-count>
836
+
```
837
+
838
+
**Step 2: Add the handler method**
839
+
840
+
Add after `#handleFavoriteClick`:
841
+
842
+
```javascript
843
+
#handleCommentClick() {
844
+
this.dispatchEvent(new CustomEvent('comment-click', {
845
+
bubbles: true,
846
+
composed: true
847
+
}));
848
+
}
849
+
```
850
+
851
+
**Step 3: Commit**
852
+
853
+
```bash
854
+
git add src/components/organisms/grain-engagement-bar.js
855
+
git commit -m "feat: make comment icon interactive in engagement bar"
856
+
```
857
+

+

+
## Task 7: Integrate comment sheet into gallery detail page
861
+
862
+
**Files:**
863
+
- Modify: `src/components/pages/grain-gallery-detail.js`
864
+
865
+
**Step 1: Add import**
866
+
867
+
Add at top with other imports:
868
+
```javascript
869
+
import '../organisms/grain-comment-sheet.js';
870
+
```
871
+
872
+
**Step 2: Add state property**
873
+
874
+
Add to `static properties`:
875
+
```javascript
876
+
_commentSheetOpen: { state: true }
877
+
```
878
+
879
+
**Step 3: Initialize in constructor**
880
+
881
+
Add to constructor:
882
+
```javascript
883
+
this._commentSheetOpen = false;
884
+
```
885
+
886
+
**Step 4: Add handler methods**
887
+
888
+
Add after `#handleBack`:
889
+
890
+
```javascript
891
+
#handleCommentClick() {
892
+
if (!auth.isAuthenticated) {
893
+
this.#showLoginDialog();
894
+
return;
895
+
}
896
+
this._commentSheetOpen = true;
897
+
}
898
+
899
+
#handleCommentSheetClose() {
900
+
this._commentSheetOpen = false;
901
+
}
902
+
903
+
#showLoginDialog() {
904
+
// Dispatch event to show login at page level
905
+
this.dispatchEvent(new CustomEvent('show-login', {
906
+
bubbles: true,
907
+
composed: true
908
+
}));
909
+
}
910
+
```
911
+
912
+
**Step 5: Add event listener to engagement bar**
913
+
914
+
Find:
915
+
```javascript
916
+
<grain-engagement-bar
917
+
```
918
+
919
+
Add the event handler:
920
+
```javascript
921
+
<grain-engagement-bar
922
+
...existing props...
923
+
@comment-click=${this.#handleCommentClick}
924
+
></grain-engagement-bar>
925
+
```
926
+
927
+
**Step 6: Add comment sheet to render**
928
+
929
+
Add before the closing `</grain-feed-layout>`:
930
+
931
+
```javascript
932
+
<grain-comment-sheet
933
+
?open=${this._commentSheetOpen}
934
+
galleryUri=${this._gallery?.uri || ''}
935
+
@close=${this.#handleCommentSheetClose}
936
+
></grain-comment-sheet>
937
+
```
938
+
939
+
**Step 7: Commit**
940
+
941
+
```bash
942
+
git add src/components/pages/grain-gallery-detail.js
943
+
git commit -m "feat: integrate comment sheet into gallery detail page"
944
+
```
945
+
946
+

947
+
948
+
## Task 8: Add close icon to grain-icon if missing
949
+
950
+
**Files:**
951
+
- Modify: `src/components/atoms/grain-icon.js`
952
+
953
+
**Step 1: Check if close icon exists**
954
+
955
+
Read the file and check if 'close' is in the icons object. If not, add it.
956
+
957
+
The close icon SVG path:
958
+
```javascript
959
+
close: 'M19 6.41L17.59 5 12 10.59 6.41 5 5 6.41 10.59 12 5 17.59 6.41 19 12 13.41 17.59 19 19 17.59 13.41 12z'
960
+
```
961
+
962
+
**Step 2: Commit (if changes made)**
963
+
964
+
```bash
965
+
git add src/components/atoms/grain-icon.js
966
+
git commit -m "feat: add close icon to grain-icon"
967
+
```
968
+
969

970
+
971
+
## Task 9: Remove old grain-comment-list from gallery detail
972
+
973
+
**Files:**
974
+
- Modify: `src/components/pages/grain-gallery-detail.js`
975
+
976
+
**Step 1: Remove import**
977
+
978
+
Remove this line:
979
+
```javascript
980
+
import '../organisms/grain-comment-list.js';
981
+
```
982
+
983
+
**Step 2: Remove usage**
984
+
985
+
Remove this block from render:
986
+
```javascript
987
+
<grain-comment-list
988
+
.comments=${this._gallery.comments}
989
+
totalCount=${this._gallery.commentCount}
990
+
></grain-comment-list>
991
+
```
992
+
993
+
**Step 3: Commit**
994
+
