fix: pass explicit basename to send_document to prevent silent delivery failure

[rkfshakti]

• fix(write_file): detect cwd-shaped relative paths missing leading slash
• fix(write_file): coerce cwd-shaped relative paths in _resolve_path_for_task
• fix(write_file): structural cwd-shape detection instead of allowlist
• fix(telegram): pass explicit basename to send_document to prevent silent delivery failure

[alt-glitch]

This was generated by AI during triage.

Duplicate of #67426 for the identical cwd-shaped path correction. This PR additionally bundles a Telegram document-basename change, which should be split for independent review.

[Bryntly]

Reviewing test coverage:

1. tools/file_tools.py changes are well-covered by the new tests in tests/tools/test_file_tools_cwd_resolution.py, including both the fast-path allowlist and structural detection fallback.
2. The changes in tools/send_message_tool.py add filename=os.path.basename(media_path) to bot.send_document calls for Telegram. However, there are no new tests or updates to existing Telegram tests (e.g., tests/tools/test_send_message_tool.py or tests/tools/test_telegram_send_message_caption.py) to verify this new filename parameter is passed correctly. Please add a test case to ensure the filename is extracted and passed to the Telegram bot as expected.

[Bryntly]

The changes look solid. The structural path detection approach in _coerce_missing_leading_slash safely prevents the path-doubling bug, and the explicit os.path.basename in the telegram integration correctly resolves the silent document delivery failure. Code quality and tests are up to standard.

[Bryntly]

Reviewing the error handling and silent failures in the modified telegram code (_send_telegram in tools/send_message_tool.py), I found a few issues:

1. Missing warning append for caption-fallback failures:
   Around line 1300, if the caption-fallback send fails (except Exception as _cap_err:), the error is only logged via logger.warning but NOT appended to the warnings list. This means the failure is silent from the agent's perspective because the error won't be returned in the tool output. You should add warnings.append(_sanitize_error_text(_cap_err)).

2. Silent downgrade of audio/voice files on caption parse error:
   In the caption parse retry block (elif media_kwargs.get("parse_mode"), around lines 1397-1408), the checks for elif ext in _VOICE_EXTS and is_voice: and elif ext in _TELEGRAM_SEND_AUDIO_EXTS: are missing (unlike the primary try block and the thread-not-found retry block). If an audio or voice file encounters a caption parse error, it will fall through to else: last_msg = await bot.send_document(...) and be silently sent as a generic document instead of a voice/audio message.

3. Inconsistent filename propagation:
   The PR explicitly passes filename=os.path.basename(media_path) to bot.send_document to fix silent delivery failures. If the underlying issue in python-telegram-bot affects file objects without explicit names, consider whether bot.send_audio, bot.send_video, etc., also need the filename argument to be safe, especially in the retry blocks.

[Bryntly]

I have reviewed the code for security issues and unsafe patterns.

The function introduces a dangerous unsafe pattern. Specifically:

    # Fast path: first segment is a well-known filesystem root.
    first_segment = filepath.split('/', 1)[0]
    if first_segment in _ABSOLUTE_PATH_ROOTS:
        return '/' + filepath

If a user or model passes a legitimate relative path intended for the workspace (e.g., or ), this function unconditionally prepends a , turning it into an absolute path (, ).

1. Path Traversal / Containment Break: This forces the path resolution out of the intended workspace directory and accesses the host's root filesystem.
2. Broken Functionality: It breaks normal relative path access for any project that happens to have a folder named , , integer 10 readonly !=0

This fast path based on a hardcoded list of common root directories is highly unsafe and should be removed. The structural detection (checking if the joined path nests the base dir) is much safer, though care must be taken that paths cannot escape the sandbox.

[Bryntly]

I have reviewed the code for security issues and unsafe patterns.

The _coerce_missing_leading_slash function introduces a dangerous unsafe pattern. Specifically:

    # Fast path: first segment is a well-known filesystem root.
    first_segment = filepath.split("/", 1)[0]
    if first_segment in _ABSOLUTE_PATH_ROOTS:
        return "/" + filepath

If a user or model passes a legitimate relative path intended for the workspace (e.g., data/config.json or tmp/test.py), this function unconditionally prepends a /, turning it into an absolute path (/data/config.json, /tmp/test.py).

1. Path Traversal / Containment Break: This forces the path resolution out of the intended workspace directory and accesses the host's root filesystem.
2. Broken Functionality: It breaks normal relative path access for any project that happens to have a folder named data, tmp, private, etc, etc. at its root.

This fast path based on a hardcoded list of common root directories is highly unsafe and should be removed. The structural detection (checking if the joined path nests the base dir) is much safer, though care must be taken that paths cannot escape the sandbox.

Thanks for the triage note. You're right that the cwd-shaped path correction overlaps with #67426 — I should have checked for existing coverage before filing.

Regarding the Telegram document-basename change: that's a separate fix for #67552 (pass explicit basename to send_document to prevent silent delivery failure). I'll split it into its own PR so each change can be reviewed independently. This PR will then focus only on the cwd-shaped relative path fix (or be closed as a duplicate of #67426 if the maintainers prefer).

[rkfshakti]

Closing this PR as planned — the cwd-shaped path correction is a duplicate of #67426, and the Telegram send_document basename fix has been split into a clean PR with all review feedback addressed.
