From 9c55d98fcd7d912b2d29d08914b4aaa5fa7ba881 Mon Sep 17 00:00:00 2001 From: agentrelaybot Date: Thu, 8 Oct 2026 15:43:54 -0700 Subject: [PATCH 01/20] fix(cli,sdk): upload file bytes before attaching; --file on DMs and posts; download attachments agent-relay message file upload serialized {type:'file',path} as the attachment id, so the server rejected every upload with 'Invalid attachments: file ids must exist in workspace and be complete' and no bytes were ever stored (#1398). - SDK: files.upload/get/download on AgentRelay and RelaycastMessagingClient, and shared uploadRelayFile/downloadRelayFile helpers (request upload, PUT bytes, complete). - CLI: --file on message dm send, message post and message dm send_group; message file upload takes --channel or --to; new message file get and message file download. - MCP: upload_file and download_file tools; send_group_dm accepts attachments.

The broker now carries attachments through the typed wire parser, tolerant fallback, and node delivery payloads; downloads each file best-effort (25 MiB cap, 20s per file, 60s per message) via GET /v1/files/{id} and its download_url into /.agent-relay/attachments// (home fallback); and appends an "Attachments:" block after the message body with the saved path, or the file id plus an `agent-relay message file download` command when not downloaded. Node deliveries with attachments are held off the event loop until their downloads finish, preserving per-agent order. Attachment-only messages are injected instead of the raw payload JSON.

The +//! broker used to drop them, so a PTY agent only ever saw the message text. +//! This module: +//! +//! - parses attachment records tolerantly (malformed entries are skipped, +//! never failing the whole event), +//! - downloads each attachment best-effort to +//! `/.agent-relay/attachments//` (falling back +//! to `~/.agent-relay/attachments/...`) through `GET /v1/files/{id}` and its +//! short-lived `download_url`, with a size cap and timeouts, and +//! - renders the `Attachments:` block appended after the message body, in +//! the same shape the desktop app renders. +//! +//! Every sender-controlled string rendered into the block is held to one +//! line, and `[`/`]` are replaced so an attachment name cannot forge a +//! `Relay message from ...

Each file is downloaded (25 MiB cap, 20 s timeout) to `/.agent-relay/attachments//`, and an `Attachments:` block after the message body gives its local path. If a file is not downloaded, the block gives its file id and an `agent-relay message file download ` command instead. Attachment-only messages are now injected rather than dropped. +- Agents spawned by the broker receive message attachments (up to 25 MiB each) as local files: the injected message ends with an `Attachments:` list giving each file's path under `.agent-relay/attachments/` in the agent's working directory, or an `agent-relay message file download ` command when a file could not be fetched. Messages that carry only attachments are now delivered too. - `@agent-relay/sdk` adds `files.upload` / `files.get` / `files.download` on `AgentRelay` and `RelaycastMessagingClient`, plus `uploadRelayFile` / `downloadRelayFile` helpers. ### Fixed -- `agent-relay message file upload` uploads the file bytes before posting, instead of sending the local path as an attachment id and failing with "Invalid attachments: file ids must exist in workspace and be complete". +- `agent-relay message file upload` now uploads and attaches the file; it always failed with "Invalid attachments: file ids must exist in workspace and be complete". ## [13.2.0] - 2026-10-08 diff --git a/crates/broker/src/attachments.rs b/crates/broker/src/attachments.rs index f9a9a636fc..6a66c5ee3a 100644 --- a/crates/broker/src/attachments.rs +++ b/crates/broker/src/attachments.rs @@ -195,7 +195,9 @@ pub(crate) fn sanitize_filename(raw: &str) -> String { .chars() .filter(|c| !c.is_control() && !is_invisible_format(*c)) .map(|c| match c { - ':' => '_', + // Characters Windows forbids in file names (the broker ships for + // Windows too), so a POSIX sender's name still saves everywhere. + ':' | '<' | '>' | '"' | '|' | '?' | '*' => '_', // Keep the saved name free of characters the injected line would // otherwise have to rewrite, so the path can be shown verbatim.
