Moss comments

Comments

Root comments need both body markers and a matching comments.json entry. Reply IDs carry a parentId, live only in comments.json, and must be reachable from a root comment.

Body Markers

Wrap the exact annotated range:

The %%m:c1:start%%current layout%%m:c1:end%% needs work.

• IDs may contain letters, numbers, hyphens, and underscores.
• Start and end markers are both required.
• Multiple comments can share one range: %%m:a,b:start%%text%%m:a,b:end%%.

Sidecar Metadata

Workspace note comments use comments.json beside the markdown file in its note directory. For a standalone external markdown file, use only the sidecar path Moss provides.

This example is for a writer editing files outside Moss. The in-app Moss agent must use "source":"agent" instead.

{"c1":{"text":"Tighten this wording.","createdAt":1707900000,"updatedAt":1707900000,"source":"external"}}

• Every body marker ID is a root comment and needs matching sidecar metadata.
• Every root comment ID needs matching body markers.
• Reply IDs with parentId live only in sidecar metadata and must be reachable from a root comment.
• When you create a comment or reply, set source to your execution context: "agent" for the in-app Moss agent, "external" for writers editing files outside Moss, and "user" only for human/UI-authored comments.
• Existing sidecars may include source or resolvedBy metadata. Preserve existing attribution fields unless the user explicitly asks to change them.
• Existing sidecars may omit source. Treat missing source as legacy/unknown; do not backfill it or infer it from context.
• Resolved comments keep their body markers and sidecar entries. Add resolvedAt (Unix timestamp in seconds), set resolvedBy to your execution context when known, and update updatedAt on the root comment and every descendant reply.

Threading

Thread replies live in comments.json; body markers only anchor root comments.

This example continues the external-writer context above.

{
  "c1": {"text":"Original.","createdAt":1707900000,"updatedAt":1707900000,"source":"user"},
  "c1-r1": {"text":"Following up.","createdAt":1707900100,"updatedAt":1707900100,"source":"external","parentId":"c1"}
}

• Only the root comment id appears in body markers. Reply ids at any depth live only in comments.json sidecar metadata.
• parentId is optional and may point at a root comment or another reply.
• A reply's source, when present, is independent of its parent's source.
• Do not create cycles or point parentId at a missing id.

Placement

• Plain text: wrap the exact words.
• Inline nodes: wrap the entire token, for example %%m:x:start%%[[Project Plan]]%%m:x:end%%.
• Block nodes: put markers on standalone lines around the whole block.

%%m:b1:start%%
![Demo](assets/demo.png)
%%m:b1:end%%

Do not place markers inside wiki links, formula/variable pills, color code pills, fenced block payloads, or raw HTML comments. Treat atomic inline pills as indivisible; wrap the whole node or surrounding phrase instead. For color literals such as #4f8a6b, rebeccapurple, or rgb(72, 67, 60), prefer annotating the surrounding sentence or phrase rather than trying to split the literal itself.

Resolving Comments

• Review every open comment before acting.
• If a comment is a question, ambiguous, asks for clarification, or needs user confirmation, reply or request clarification and leave it open.
• If a comment is clear and actionable, apply the requested change to the note.
• Once the requested change has been applied, resolve the whole thread by setting resolvedAt, resolvedBy, and updatedAt on the root comment and every descendant reply.
• Do not remove comment body markers or sidecar metadata when resolving. Resolved comments remain in comments.json and are hidden by default in the UI.
• Deleting a comment thread is a separate user-level action with confirmation. Delete removes the root body markers and sidecar entries for the root plus descendants.

In-App Agent Comment Context

When the in-app Moss agent receives comment context from the prompt box, the prompt carries compact comment IDs instead of full quoted comment text.

• Look up the listed root IDs and message IDs in the active note's comments sidecar before editing.
• Use the active note body markers to locate the annotated ranges.
• Edit the note body to address the requested comments.
• Edit the active note's comments sidecar directly when adding replies, adding comments, or resolving threads. Keep valid JSON and preserve unrelated metadata.
• When adding a comment or reply from the in-app agent, set source to "agent"; external writers editing files outside Moss should set "external".
• When the requested change is complete, resolve the root comment and every descendant by setting resolvedAt, resolvedBy, and updatedAt.
• If a comment is ambiguous or still needs clarification, reply in comments.json or leave it open; do not set resolved fields.
• The in-app agent may write only the active note's comments sidecar. External writers outside the app may edit sidecars directly when they have filesystem access.

Image Attachments

Comments may include image attachments stored under the note's assets/ directory:

This example also uses external-writer attribution; the in-app Moss agent must use "source":"agent".

{"c1":{"text":"See screenshot.","createdAt":1707900000,"updatedAt":1707900000,"source":"external","imageUrls":["assets/comment-abc.png"]}}

• Use the imageUrls array with note-relative paths under assets/.
• To read an attached image, resolve the path against the note's directory and read the file from assets/.

@Mentions

Mentions in comment text are references to notes, files, or folders. Each displayed mention is wrapped with U+2063 (INVISIBLE SEPARATOR) before and U+2064 (INVISIBLE PLUS) after, e.g. Re: ⁣@Project Plan⁤ scope.

• When a comment asks you to use or inspect an @mention, use the available mention id/path or note sidecar metadata to resolve and read the referenced target before acting.
• Mentioned targets may be inside or outside the Moss notes directory; do not assume ~/Moss/Notes/.
• If the mention cannot be resolved or multiple targets match, report the ambiguity instead of inventing a path.
• Preserve the wrappers verbatim when editing existing comment text — the renderer uses them to display the mention as a pill.
