fix(send_message_tool): add sendRichMessage fast-path for Telegram

[michaeltanyk]

Problem

The send_message tool's _send_telegram function creates a raw Bot object and calls bot.sendMessage(parse_mode=MarkdownV2). It bypasses the gateway's rich message path entirely. Tables, task lists, math, and other rich constructs always degrade to bulleted lists when sent via the send_message tool.

Agent streaming responses work fine (they go through the gateway adapter's rich path), but any explicit send_message call — notifications, cron outputs, cross-channel messages — gets MarkdownV2 degradation.

Fix

Two additions to tools/send_message_tool.py:

1. _RichMsg helper class — wraps the message_id from sendRichMessage responses so the return-value pipeline (which expects a message object) works unchanged.

2. Rich fast-path in _send_telegram — before the existing MarkdownV2 path, tries bot.do_api_request("sendRichMessage", ...) with rich_message: {markdown: ...}. On any failure, falls through to the existing MarkdownV2 path — purely additive, zero regression risk.

Verification

Tested on a Hermes instance with Telegram PTB 22.6+:

grep "sendRichMessage" agent.log | tail -5
# Shows sendRichMessage calls with rich_message.blocks containing native table/list/heading blocks

Tables, task lists, blockquotes, and math expressions now render natively when sent via the send_message tool.

By default, 'file' is written in the MIFF image format. To
specify a particular image format, precede the filename with an image
format name and a colon (i.e. ps:image) or specify the image type as
the filename suffix (i.e. image.ps). Specify 'file' as '-' for
standard input or output. on every Telegram message send**

The rich-path guard does import inspect inside the hot path of _send_telegram, which runs on every message. Python module imports are cached after first load, but the import machinery still acquires the import lock and walks sys.modules on each call — nontrivial overhead on a per-message basis.

Move it to the top of the file:

import inspect  # module-level

Then the hot-path check becomes just:

if inspect.iscoroutinefunction(getattr(bot, "do_api_request", None)):

Everything else looks solid — clean fallback to legacy MarkdownV2 on any failure, correct scoping inside _send_telegram, and the _RichMsg carrier is a good minimal shim.

Good catch — moved import inspect to module level in 068d2d0. The import lock and sys.modules walk on every message send was unnecessary overhead.

Code Review Summary

Verdict: Approved

Adds sendRichMessage fast-path for Telegram in send_message_tool, avoiding the generic JSON path.

Looks Good

• Clean targeted optimization for Telegram platform.
• No impact on other platforms.

Thanks for identifying a real standalone-send gap. Current main still routes Telegram send_message through tools/send_message_tool.py:849-859 and _send_telegram, whose text loop uses bot.send_message at tools/send_message_tool.py:1228-1246.

Problems

• The proposed fast path sends every non-HTML body as rich. Current adapter policy intentionally limits rich delivery to qualifying constructs and skips known unsafe shapes in plugins/platforms/telegram/adapter.py:1393-1462.
• The proposed catch-all fallback can duplicate delivery after a timeout or other transient failure. The current rich path specifically returns such failures without a legacy resend in plugins/platforms/telegram/adapter.py:1545-1691.
• The raw payload omits the current line-break normalization and successful-send reply index used by plugins/platforms/telegram/adapter.py:1506-1521 and :1700-1707.

Suggested changes

• Share or extract the adapter's eligibility, payload, error-classification, and rich-send recording behavior for the standalone sender.
• Add standalone-path coverage for successful rich delivery, permanent fallback, transient no-resend, and the configured safety gates.

Automated hermes-sweeper review.

[teknium1]

Please do not route every non-HTML body through rich delivery. Current Telegram policy only selects qualifying rich constructs and also skips known unsafe details+math/CJK shapes (plugins/platforms/telegram/adapter.py:1393-1462); this standalone path needs to preserve those gates and the rich_messages configuration.

[teknium1]

This catch-all fallback can duplicate a message when the rich request times out after Telegram accepted it. The adapter only falls back for permanent/capability failures and returns transient failures without a legacy resend (plugins/platforms/telegram/adapter.py:1545-1691). Please share that classification here.

Thanks for the review. I worked with my AI agent on the initial PR, but the plugin migration changes you've outlined are beyond me — I'm not familiar with that part of the codebase.

I'm currently in a country with internet restrictions and fighting infrastructure fires just to stay connected, so I don't have the bandwidth to dig in properly, and I won't let my agent touch the code without me reviewing it.

I'm respectfully recusing myself from this PR. Please take the idea and run with it, or close if it's not worth the team's time. Apologies for the noise, and thanks for the thoughtful review.
