* fix(gateway): avoid premature agent.wait completion on transient errors
* fix(agent): preemptively guard tool results against context overflow
* fix: harden tool-result context guard and add message_id metadata
* fix: use importOriginal in session-key mock to include DEFAULT_ACCOUNT_ID
The run.skill-filter test was mocking ../../routing/session-key.js with only
buildAgentMainSessionKey and normalizeAgentId, but the module also exports
DEFAULT_ACCOUNT_ID which is required transitively by src/web/auth-store.ts.
Switch to importOriginal pattern so all real exports are preserved alongside
the mocked functions.
* pi-runner: guard accumulated tool-result overflow in transformContext
* PI runner: compact overflowing tool-result context
* Subagent: harden tool-result context recovery
* Enhance tool-result context handling by adding support for legacy tool outputs and improving character estimation for message truncation. This includes a new function to create legacy tool results and updates to existing functions to better manage context overflow scenarios.
* Enhance iMessage handling by adding reply tag support in send functions and tests. This includes modifications to prepend or rewrite reply tags based on provided replyToId, ensuring proper message formatting for replies.
* Enhance message delivery across multiple channels by implementing sticky reply context for chunked messages. This includes preserving reply references in Discord, Telegram, and iMessage, ensuring that follow-up messages maintain their intended reply targets. Additionally, improve handling of reply tags in system prompts and tests to support consistent reply behavior.
* Enhance read tool functionality by implementing auto-paging across chunks when no explicit limit is provided, scaling output budget based on model context window. Additionally, add tests for adaptive reading behavior and capped continuation guidance for large outputs. Update related functions to support these features.
* Refine tool-result context management by stripping oversized read-tool details payloads during compaction, ensuring repeated read calls do not bypass context limits. Introduce new utility functions for handling truncation content and enhance character estimation for tool results. Add tests to validate the removal of excessive details in context overflow scenarios.
* Refine message delivery logic in Matrix and Telegram by introducing a flag to track if a text chunk was sent. This ensures that replies are only marked as delivered when a text chunk has been successfully sent, improving the accuracy of reply handling in both channels.
* fix: tighten reply threading coverage and prep fixes (#19508) (thanks @tyler6204)
resolveTelegramThreadSpec now checks isForum in the non-group path.
DMs with forum/topics enabled return scope 'forum' so each topic
gets its own session, while plain DM threads keep scope 'dm'.
Catch GrammyError when getFile fails for files >20MB (Telegram Bot API limit).
Log warning, skip attachment, but continue processing message text.
- Add FILE_TOO_BIG_RE regex to detect 'file is too big' errors
- Add isFileTooBigError() and isRetryableGetFileError() helpers
- Skip retrying permanent 400 errors (they'll fail every time)
- Log specific warning for file size limit errors
- Return null so message text is still processed
Fixes#18518
* fix(telegram): auto-wrap file references with TLD extensions to prevent URL previews
Telegram's auto-linker aggressively treats filenames like HEARTBEAT.md,
README.md, main.go, script.py as URLs and generates domain registrar previews.
This fix adds comprehensive protection for file extensions that share TLDs:
- High priority: .md, .go, .py, .pl, .ai, .sh
- Medium priority: .io, .tv, .fm, .am, .at, .be, .cc, .co
Implementation:
- Added wrapFileReferencesInHtml() in format.ts
- Runs AFTER markdown→HTML conversion
- Tokenizes HTML to respect tag boundaries
- Skips content inside <code>, <pre>, <a> tags (no nesting issues)
- Applied to all rendering paths: renderTelegramHtmlText, markdownToTelegramHtml,
markdownToTelegramChunks, and delivery.ts fallback
Addresses review comments:
- P1: Now handles chunked rendering paths correctly
- P2: No longer wraps inside existing code blocks (token-based parsing)
- No lookbehinds used (broad Node compatibility)
Includes comprehensive test suite in format.wrap-md.test.ts

* fix(telegram): prevent URL previews for file refs with TLD extensions
Two layers were causing spurious link previews for file references like
`README.md`, `backup.sh`, `main.go`:
1. **markdown-it linkify** converts `README.md` to
`<a href="http://README.md">README.md</a>` (.md = Moldova TLD)
2. **Telegram auto-linker** treats remaining bare text as URLs
## Changes
### Primary fix: suppress auto-linkified file refs in buildTelegramLink
- Added `isAutoLinkedFileRef()` helper that detects when linkify auto-
generated a link from a bare filename (href = "http://" + label)
- Rejects paths with domain-like segments (dots in non-final path parts)
- Modified `buildTelegramLink()` to return null for these, so file refs
stay as plain text and get wrapped in `<code>` by the wrapper
### Safety-net: de-linkify in wrapFileReferencesInHtml
- Added pre-pass that catches auto-linkified anchors in pre-rendered HTML
- Handles edge cases where HTML is passed directly (textMode: "html")
- Reuses `isAutoLinkedFileRef()` logic — no duplication
### Bug fixes discovered during review
- **Fixed `isClosing` bug (line 169)**: the check `match[1] === "/"`
was wrong — the regex `(<\/?)}` captures `<` or `</`, so closing
tags were never detected. Changed to `match[1] === "</"`. This was
causing `inCode/inPre/inAnchor` to stay stuck at true after any
opening tag, breaking file ref wrapping after closing tags.
- **Removed double `wrapFileReferencesInHtml` call**: `renderTelegramHtmlText`
was calling `markdownToTelegramHtml` (which wraps) then wrapping again.
### Test coverage (+12 tests, 26 total)
- `.sh` filenames (original issue #6932 mentioned backup.sh)
- Auto-linkified anchor replacement
- Auto-linkified path anchor replacement
- Explicit link preservation (different label)
- File ref after closing anchor tag (exercises isClosing fix)
- Multiple file types in single message
- Real URL preservation
- Explicit markdown link preservation
- File ref after real URL in same message
- Chunked output file ref wrapping
Closes#6932
* test(telegram): add comprehensive edge case coverage for file ref wrapping
Add 16 edge case tests covering:
- File refs inside bold/italic tags
- Fenced code blocks (no double-wrap)
- Domain-like paths preserved as links (example.com/README.md)
- GitHub URLs with file paths
- wrapFileRefs: false behavior
- All TLD extensions (.ai, .io, .tv, .fm)
- Non-TLD extensions not wrapped (.png, .css, .js)
- File ref position (start, end, multiple in sequence)
- Nested paths without domain segments
- Version-like paths (v1.0/README.md wraps, example.com/v1.0/README.md links)
- Hyphens and underscores in filenames
- Uppercase extensions
* fix(telegram): use regex literal and depth counters for tag tracking
Code review fixes:
1. Replace RegExp constructor with regex literal for autoLinkedAnchor
- Avoids double-escaping issues with \s
- Uses backreference \1 to match href=label pattern directly
2. Replace boolean toggles with depth counters for tag nesting
- codeDepth, preDepth, anchorDepth track nesting levels
- Correctly handles nested tags like <pre><code>...</code></pre>
- Prevents wrapping inside any level of protected tags
Add 4 tests for edge cases:
- Nested code tags (depth tracking)
- Multiple anchor tags in sequence
- Auto-linked anchor with backreference match
- Anchor with different href/label (no match)
* fix(telegram): add escapeHtml and escapeRegex for defense in depth
Code review fixes:
1. Escape filename with escapeHtml() before inserting into <code> tags
- Prevents HTML injection if regex ever matches unsafe chars
- Defense in depth (current regex already limits to safe chars)
2. Escape extensions with escapeRegex() before joining into pattern
- Prevents regex breakage if extensions contain metacharacters
- Future-proofs against extensions like 'c++' or 'd.ts'
Add tests documenting regex safety boundaries:
- Filenames with special chars (&, <, >) don't match
- Only [a-zA-Z0-9_.\-./] chars are captured
* fix(telegram): catch orphaned single-letter TLD patterns
When text like 'R&D.md' doesn't match the main file pattern (because &
breaks the character class), the 'D.md' part can still be auto-linked
by Telegram as a domain (https://d.md/).
Add second pass to catch orphaned TLD patterns like 'D.md', 'R.io', 'X.ai'
that follow non-alphanumeric characters and wrap them in <code> tags.
Pattern: ([^a-zA-Z0-9]|^)([A-Za-z]\.(?:extensions))(?=[^a-zA-Z0-9/]|$)
Tests added:
- 'wraps orphaned TLD pattern after special character' (R&D.md → R&<code>D.md</code>)
- 'wraps orphaned single-letter TLD patterns' (X.ai, R.io)
* refactor(telegram): remove popular domain TLDs from file extension list
Remove .ai, .io, .tv, .fm from FILE_EXTENSIONS_WITH_TLD because:
- These are commonly used as real domains (x.ai, vercel.io, github.io)
- Rarely used as actual file extensions
- Users are more likely referring to websites than files
Keep: md, sh, py, go, pl (common file extensions, rarely intentional domains)
Keep: am, at, be, cc, co (less common as intentional domain references)
Update tests to reflect the change:
- Add test for supported extensions (.am, .at, .be, .cc, .co)
- Add test verifying popular TLDs stay as links
* fix(telegram): prevent orphaned TLD wrapping inside HTML tags
Code review fixes:
1. Orphaned TLD pass now checks if match is inside HTML tag
- Uses lastIndexOf('<') vs lastIndexOf('>') to detect tag context
- Skips wrapping when between < and > (inside attributes)
- Prevents invalid HTML like <a href="...&<code>D.md</code>">
2. textMode: 'html' now trusts caller markup
- Returns text unchanged instead of wrapping
- Caller owns HTML structure in this mode
Tests added:
- 'does not wrap orphaned TLD inside href attributes'
- 'does not wrap orphaned TLD inside any HTML attribute'
- 'does not wrap in HTML mode (trusts caller markup)'
* refactor(telegram): use snapshot for orphaned TLD offset clarity
Use explicit snapshot variable when checking tag positions in orphaned
TLD pass. While JavaScript's replace() doesn't mutate during iteration,
this makes intent explicit and adds test coverage for multi-TLD HTML.

* fix(telegram): prevent orphaned TLD wrapping inside code/pre tags
- Add depth tracking for code/pre tags in orphaned TLD pass
- Fix test to expect valid HTML output
- 55 tests now covering nested tag scenarios

* fix(telegram): clamp depth counters and add anchor tracking to orphaned pass
- Clamp depth counters at 0 for malformed HTML with stray closing tags
- Add anchor depth tracking to orphaned TLD pass to prevent wrapping
inside link text (e.g., <a href="...">R&D.md</a>)
- 57 tests covering all edge cases

Fixes#9545 and #9351.
When a message comes from a Telegram forum topic, the peer ID includes
the topic suffix (e.g., `-1001234567890:topic:99`). Users configure
bindings with the base group ID, which previously did not match.
This adds `parentPeer` to `resolveAgentRoute()` calls for forum groups,
enabling binding inheritance from the parent group to all topics.
- Extract `buildTelegramParentPeer()` helper in bot/helpers.ts
- Pass parentPeer in bot-message-context.ts, bot-handlers.ts,
bot-native-commands.ts, and bot.ts (reaction handler)
- Add tests for forum topic routing and topic precedence
* Telegram: remove @ts-nocheck from bot.ts and bot-message-dispatch.ts
- bot/types.ts: TelegramContext.me uses UserFromGetMe (Grammy) instead of manual inline type
- bot.ts: remove 6 unsafe casts (as any, as unknown, as object), use Grammy types directly
- bot.ts: remove dead message_thread_id access on reactions (not in Telegram Bot API)
- bot.ts: remove resolveThreadSessionKeys import (no longer needed for reactions)
- bot-message-dispatch.ts: replace ': any' with DispatchTelegramMessageParams type
- bot-message-dispatch.ts: add sticker.fileId guard before cache access
- bot.test.ts: update reaction tests, remove dead DM thread-reaction test
* Telegram: remove duplicate bot.catch handler (only the last one runs in Grammy)
* Telegram: remove @ts-nocheck from bot.ts, fix duplicate error handler, harden sticker caching (#9077)
Extract missing metadata from forwarded Telegram messages:
- Add fromChatType to TelegramForwardedContext, capturing the original
chat type (channel/supergroup/group) from forward_from_chat.type
and forward_origin.chat/sender_chat.type
- Add fromMessageId to capture the original message ID from channel forwards
- Read author_signature from forward_origin objects (modern API),
preferring it over the deprecated forward_signature field
- Pass ForwardedFromChatType and ForwardedFromMessageId through to
the inbound context payload
- Add test coverage for forward_origin channel/chat types, including
author_signature extraction and fromChatType propagation
Previous fix only checked skippedEmpty > 0, but when model returns
content: [] no payloads are created at all. Now also checks
replies.length === 0 to catch this case.

- Add msg.video_note to media extraction chain in bot/delivery.ts
- Add placeholder detection for video notes in bot-message-context.ts
- Video notes (rounded square video messages) are now processed and downloaded like regular videos
Fixes issue where video note messages were silently dropped because they weren't in the media handling logic.
