🧭 Context

@wolfstar/plugin-gateway already sends files and describes them in attachments through MessagePayload, and already has the received Attachment. What was missing is discord.js's way to build a file: AttachmentBuilder. MessagePayload even documents "an attachment builder" as an accepted files entry, but there was none to use.

📚 Description

Adds AttachmentBuilder with discord.js v14's API, so code ported from discord.js keeps working: new AttachmentBuilder(file, { name, description }), the chainable setFile, setName, setDescription and setSpoiler, the spoiler getter, toJSON() and AttachmentBuilder.from(other). It also has setTitle, setDuration and setWaveform, because AttachmentPayload already supports them (voice messages).

setSpoiler adds or removes the SPOILER_ prefix of the name, as in discord.js. When the name is not set yet (it is inferred from a path or URL when sending), the builder remembers the flag and MessagePayload prefixes the inferred name.

Attachment#attachment now returns the URL of a received attachment, as in discord.js. That makes AttachmentBuilder.from(message.attachments.first()) work to resend a file.

I did not change the rest of Attachment: name, spoiler, duration, flags and createdAt were already there. I could not check what discord.js v15 keeps of this API, so this follows v14.

Correctness · messages/AttachmentBuilder.ts:213 · in Attachment Builder

Copying a named AttachmentPayload with spoiler: true drops the flag, so the copied file uploads without Discord’s spoiler cover.

Fix: In AttachmentBuilder.from, apply setSpoiler() whenever other.spoiler is true, including when the copied name is set.

   Problem: Copying a named payload drops its spoiler flag. Copying a named `AttachmentPayload` with `spoiler: true` drops the flag, so the copied file uploads without Discord's spoiler cover.
   Fix: In `AttachmentBuilder.from`, apply `setSpoiler()` whenever `other.spoiler` is true, including when the copied name is set.

🪧 More tips

• Run npx skills add coldteadotai/pr-lens, then tell your coding agent: "Diagram the change you just made with PR Lens and attach it to the pull request."
• Run npx @coldtea/pr-lens-cli analyze --base origin/main on a branch, then npx @coldtea/pr-lens-cli render .pr-lens/graph.json. Same lenses, your own model key, before the pull request exists
• Untick Architecture lens or Data flow lens under View to hide a diagram, or tick Expand every detail to open every section. The comment redraws in a few seconds
• Click the link under each diagram to open it on a canvas you can zoom, pan and step through
• The diagrams are links. Click one to open it on the canvas, then press W or click play to walk through the change
• The CLI's render reads .github/pr-lens.yml and applies your renames, exclusions and lane pins at draw time
• Set github.comment.collapsed: true in .github/pr-lens.yml to fold the comment behind one View architecture and data flow row. Drawing still runs as before
• Set github.draw: on-demand in .github/pr-lens.yml and PR Lens stops drawing pull requests on its own. Comment @pr-lens draw on a pull request when you want that one drawn
• Add .github/workflows/pr-lens.yml with coldteadotai/pr-lens/packages/action@v0 and your model provider's key as its api-key to run PR Lens from your own CI. Any /chat/completions endpoint works
• Push a commit and the drawing stays, with a note that it is out of date. Tick Redraw in the note to draw the new head
• Switch GitHub to dark mode and the diagrams follow. The moving dots are this pull request's data in motion

ℹ️ No critical issues — one small behavioral gap in AttachmentBuilder.from.

Reviewed changes

Reviewed the full diff of the single commit, cross-checked against MessagePayload (resolveFile, attachmentPayload, resolveAttachments) and the Attachment base class.

• AttachmentBuilder — discord.js v14-style builder with chainable setters, spoiler getter, toJSON() and from(), plus deferred spoiler handling when no name is set yet.
• Attachment#attachment — getter returning url, so AttachmentBuilder.from(received) works.
• Tests, type contracts, README, changeset — cover setters, spoiler handling, from, and sending through MessagePayload.

✅ No new issues found.

Reviewed changes

Reviewed the incremental delta since the prior pullfrog review (0ae2455 → 2b29755).

• AttachmentBuilder.from keeps the spoiler of named sources — it now calls setSpoiler() whenever the source is a spoiler, so a named payload or a received Attachment with the IsSpoiler flag gets the SPOILER_ prefix, and an unnamed one keeps the pending flag. This resolves the prior inline finding.
• New test for from with spoilers — covers named, unnamed, flagged received Attachment and non-spoiler sources.
