Threads Reply Drafter

Threads Reply Drafter

Drafts a reply in a conversation, or a quote post, for a specific Threads post. On Threads a reply to another user is a separate post that references the original. Replies nest naturally: there is no LinkedIn-style 2-level flattening and no parent-comment URN to resolve.

When to use

• User pastes a Threads post URL and says "reply to this"
• A creator replied to the user and they want to continue the conversation
• User wants to quote-post a take and add value (not a cheap dunk)

Input

A Threads post URL (threads.net/@HANDLE/post/CODE or the threads.com equivalent), plus the post text (and any conversation context) pasted by the user, since this bundle has no built-in post reader.

Output

• 1-3 reply or quote-post drafts, each under 500 chars
• A reply vs quote post recommendation with the reason
• A short context summary (who said what)
• An approval card. On approval the draft is returned as a copy-paste block.

Reply vs quote post

| Use a reply when | Use a quote post when | |---|---| | You are adding to the conversation in place | Your addition deserves its own reach | | You are answering a question or engaging a creator | Your followers should see the original for context | | You want intimacy over reach | You want reach and a take on your own timeline |

Default to a reply for direct engagement and a quote post when the user's point is strong enough to stand as its own post. Never quote-dunk on a small account; add value or skip it. Keep the tone warm, this is Threads.

Steps

1. Parse the URL. lib.url_parser.parse_threads_url(url) returns handle,

post_id, canonical_url.

1. Read the context. Ask the user to paste the target post and the relevant

conversation above it. If the user is already in the thread, include their prior post.

1. Decide reply vs quote post using the table above. Recommend one, but let

the user override.

1. Draft 1-3 variants using references/reply-templates.md. If the

counterpart asked a question, answer it plainly with one real detail. If they pushed back, concede then sharpen. Keep it warm.

1. Humanizer pass. Strip em dashes, AI vocab. Keep each variant under 500

chars and one hashtag max. One idea per reply.

1. Approval card. Show the conversation context, the variants, the

reply-vs-quote recommendation, and the target URL.

1. On approval. Call `lib.publish(kind="reply", draft_text=,

target_url=) for a reply, or kind="quote" for a quote post. A reply to another user has no Publora endpoint (create-post cannot target someone else's post), so kind="reply" always returns a copy-paste block. A kind="quote"` could in principle post a new post containing the original URL via Publora, but the default is still copy-paste so the user controls the embed. Paste it on Threads yourself.

The no-flattening note

Unlike LinkedIn (which flattens reply threads to 2 levels and needs the top-level comment URN as the parent), Threads nests replies naturally. There is no parent-comment URN to compute. A reply is simply a new post you publish while replying to the target post. This skill therefore does not walk any comment tree; it just drafts the text and hands it back for you to post as the reply.

Templates (references/reply-templates.md)

• R1 Answer-Their-Question - they asked, you answer plainly plus one real detail
• R2 Concede-Then-Sharpen - "fair, and the part i would push on is Y"
• R3 Extend-Their-Point - take their point one layer deeper with a new framing
• R4 Share-Lived-Experience - "we hit this last quarter, here is what broke"
• R5 Value-Add Quote - quote post that adds the missing nuance (T4 shape)

Hard rules

Global voice rules: see root SKILL.md Voice rules. Additional skill-specific rules:

• Under 500 chars, one hashtag max. Replies are tighter than posts.
• Never paste a canned "great point!". Respond with content or do not reply.
• Do not hard-sell the user's product in a reply on someone else's post.

Describe what they do instead.

• Never quote-dunk on a small account. Add value or skip it.
• Keep it warm and conversational. Threads is not the place for a cold X dunk.

Example

> User: "Reply to this: https://www.threads.net/@somebuilder/post/C8H9abcDEf" > > Skill: parses -> handle somebuilder, post C8H9abcDEf. Asks the user to paste > the post. User pastes a take about pricing. Skill recommends a reply (direct > engagement), drafts an R2 Concede-Then-Sharpen variant and an R3 > Extend-Their-Point variant, each under 500 chars. Shows the approval card. > > User: "post the first one" > > Skill: returns the copy-paste block with the target URL for the user to post as > a reply on Threads.
