Second follow-up for salvaged PR #94547, folding in review findings from the
duplicate-PR cluster (#47015, #55054, #58476, #72977, #73685 all fix the
same 401) and the sweeper review of #73685:
- Replace the dot-anchored suffix predicate with exact-match against the
existing _ALLOWED_TEAMS_SERVICE_HOSTS allowlist (two of the five
duplicate PRs converged on this independently). Any Azure customer can
register <name>.trafficmanager.net profiles, so suffix matching was not
safe. Also requires https on the default port — :444 on an allowlisted
host no longer receives the bearer (sweeper finding on #73685).
- Stream _fetch_attachment_bytes through _read_httpx_body_with_limit
instead of buffering response.content — the shared inbound media cap now
applies to authenticated downloads too (sweeper finding: a lying
Content-Length must not OOM the gateway).
- Serialize token refresh with a lazily-bound asyncio.Lock so concurrent
attachments share one STS POST (review finding on #94547).
- Token expiry now uses time.monotonic() (from #55054) — wall-clock jumps
can't extend a stale token.
- Tests updated: exact-allowlist predicate (lookalike/subdomain/port/scheme
negatives), streaming fake client, and a concurrent-cold-cache lock test.
Mutation-checked: suffix match, silent drop, no-lock, and unbounded
buffer each fail a test.
Follow-up for salvaged PR #94547 (Sibbern's Bot Framework attachment auth):
- The host check used bare endswith('trafficmanager.net') /
endswith('botframework.com'), which matched attacker lookalike hosts
(evil-trafficmanager.net) — sending the bot's bearer token off-platform.
Same threat model _ALLOWED_TEAMS_SERVICE_HOSTS already documents. Now a
single dot-anchored predicate, _is_botframework_attachment_host(),
used by both _fetch_attachment_bytes and the _on_message image branch
(was copy-pasted in two places).
- BF images whose bytes fail image validation were silently dropped with
no log (cache_media_bytes returns None; old path logged). Add the
missing else-warning, mirroring the document branch.
- Record cached_m.media_type instead of the raw content_type so the
MessageEvent MIME matches what was actually cached.
- Init _bf_token_cache in __init__ (was masked by getattr).
- Tests: host predicate dot-anchoring (attacker lookalikes blocked),
BF routing vs generic helper, bearer attach + attacker-host block end
to end, token acquire + cache reuse, token-failure degradation, and
the silent-drop regression guard. Mutation-checked: reverting the
dot-anchor, the else-warning, or the token cache each fails a test.
Pin the NoneType crash: TEAMS_SDK_AVAILABLE true plus a failed bind must
return False without calling App(). Also pin plugin import when the
microsoft_teams parent namespace is missing.
- gateway/config.py: rewrite the stale enablement-pass header comment that
still described check_fn as 'the single source of truth for are-my-env-
vars-set' / 'lazy-installs it' — both false under the new contract.
- teams: check_requirements docstring wrongly claimed credential checks
(body checks only SDK/aiohttp presence); derive install_hint from the
canonical LAZY_DEPS pins + sys.executable instead of hardcoding
'~/.hermes/hermes-agent/venv/bin/pip' and version pins (wrong under
HERMES_HOME overrides / profile installs; pins go stale on CVE bumps);
connect() fatal-error hints now point at the venv pip instead of bare
system pip (the PEP 668 trap the docs warn about).
- teams docs: drop exact version pins from the two manual-install commands
(LAZY_DEPS is the source of truth; unpinned installs still work and the
text can't go stale).
- hermes_cli/status.py: per-entry exception guard around check_fn so one
raising probe can't abort the listing of all remaining plugin platforms
(aligns with the other three call sites).
- tests: rename test_register_check_fn_is_active_lazy_installer ->
test_register_splits_passive_probe_from_active_installer (name said the
opposite of what it verifies).
PlatformEntry.check_fn served three contradictory roles: adapter-creation
gate, config auto-enablement gate, and status display. Plugins had to pick
one function for all three:
- Active installer as check_fn (discord/slack/telegram/matrix/dingtalk/
feishu): every status display could pip-install SDKs as a side effect
(the desktop 94% boot-loop class).
- Passive probe as check_fn (teams, wecom_callback): create_adapter()
returned None before connect() could lazy-install, so the SDK never
installed (#79812 deadlock; wecom_callback's platform.wecom_callback
LAZY_DEPS entry was dead code).
The split makes both call sites correct by construction:
- check_fn is now contractually PASSIVE (probe only, never installs).
- New optional PlatformEntry.ensure_deps_fn is the ACTIVE installer;
create_adapter() runs it exactly when check_fn is False — the platform
is enabled+configured and the gateway is about to connect it.
- Config enablement keeps a configured platform whose deps are missing
but installable; the install itself is deferred to create_adapter().
- Status surfaces (_platform_status, hermes status) read only the
passive probe and can never trigger pip.
Migrated all lazy-installable platform plugins to the split; platforms
with no optional deps (irc/ntfy/buzz/simplex/line/a2a/...) are unchanged
— no ensure_deps_fn means a False check_fn stays a hard block.
wecom_callback gains a working installer for the first time.
Builds on @xxxigm's #79812 (both commits cherry-picked with authorship
preserved), reworking the check_fn swap into the two-field split so the
Teams fix doesn't reintroduce install-on-status.
Platform registry create_adapter() gates on check_fn before the adapter
exists, so wiring the passive probe permanently blocked connect() and
the existing check_teams_requirements() lazy-install never ran.
Teknium review on #62947: os.environ.clear()/update around deferred
loaders is unsafe under concurrency and misses teams_pipeline's direct
adapter import.
Defer microsoft_teams binding in the Teams adapter, no-op
dotenv.load_dotenv while the SDK imports, keep api_server explicit
disable, and add SDK-import + load_gateway_config canaries.
Fixes#62935
Teams overrode send_image/send_image_file but not send_video, send_voice,
or send_document — so when the gateway dispatched a video/voice/document
reply to a Teams chat it fell through to the base-class text fallback and
sent the local file path as plain text (same broken-UX class as the LINE
URL-image gap in #49298).
Extract the existing send_image attachment logic into a shared
_send_media_attachment helper (remote URL by reference, local file as a
base64 data URI, MIME guessed from the path) and route all four media
kinds through it. 5 new tests cover remote-URL, local-file base64,
no-app, and missing-file paths.
* fix(teams): package Microsoft Teams SDK as an installable extra
The Teams adapter imports the microsoft-teams-apps SDK, but it was never
declared as a dependency, so source/local installs hit ImportError and the
adapter silently reported the SDK as unavailable. Add a 'teams' extra
(microsoft-teams-apps==2.0.13.4 + aiohttp) and document 'uv sync --extra teams'.
Per the 2026-05-12 [all] policy, opt-in messaging-platform SDKs are NOT added
to [all] (they would break every fresh install on a quarantined release); the
teams extra is installed on demand like the other platform backends.

* chore: map rio-jeong contributor email for attribution (#43945)
* feat(teams): lazy-install the Teams SDK on demand (parity with other channels)
The teams extra alone left Teams as the only messaging platform that wouldn't
auto-install its SDK — every other channel (telegram, discord, slack, matrix,
dingtalk, feishu) lazy-installs via tools.lazy_deps on first connect. Bring
Teams to parity:
- Add 'platform.teams' to LAZY_DEPS (microsoft-teams-apps + aiohttp).
- Replace the passive 'check_teams_requirements = check_requirements' alias with
a real lazy-installer that calls ensure_and_bind('platform.teams', ...),
rebinding all Teams SDK globals on success (mirrors check_slack_requirements).
- Call check_teams_requirements() at the top of TeamsAdapter.connect() so
enabling Teams installs the SDK on demand.
- Keep the passive check_requirements() as the registry check_fn so 'gateway
status' probes never trigger a pip install.
The 'teams' extra remains for packagers / explicit 'uv sync --extra teams'.
Tests: rework the alias test into shortcircuit + lazy-install assertions, and
update test_connect_fails_without_sdk to simulate an uninstallable SDK.

The Teams adapter only handled image/* attachments — documents (the
application/vnd.microsoft.teams.file.download.info consent-free download
payload and any direct-URL non-image attachment) never reached media_urls
at all, so run.py's document-context injection had nothing to surface.
Completes the class-wide sweep from PR #44695 (Signal/Email/SimpleX).
- download.info attachments: fetch the pre-authed SharePoint downloadUrl
(SSRF-guarded, same guard chain as base.py cache_*_from_url) and route
through cache_media_bytes
- direct-URL non-image attachments: same fetch + classify path
- skip Teams' text/html message-body mirror and adaptive-card attachments
- DOCUMENT > PHOTO > VIDEO > AUDIO precedence for mixed attachments,
matching the Email precedence rationale from #44695
Remove unused imports (F401) and duplicate/shadowed import
redefinitions (F811) across the codebase using ruff's safe
autofixes. No behavioral changes -- imports only.
- ~1400 safe autofixes applied across 644 files (net -1072 lines)
- __init__.py re-exports preserved (excluded from F401 removal so
public re-export surfaces stay intact)
- Re-exports that are imported or monkeypatched by tests but look
unused in their defining module are kept with explicit # noqa:
F401 (gateway/run.py load_dotenv; run_agent re-exports from
agent.message_sanitization, agent.context_compressor,
agent.retry_utils, agent.prompt_builder, agent.process_bootstrap,
agent.codex_responses_adapter)
- Unsafe F841 (unused-variable) fixes deliberately skipped -- those
can change behavior when the RHS has side effects
- ruff lints remain disabled in pyproject.toml (only PLW1514 is
selected); this is a one-time cleanup, not a config change
Verification:
- python -m compileall: clean
- pytest --collect-only: all 27161 tests collect (zero import errors)
- core entry points import clean (run_agent, model_tools, cli,
toolsets, hermes_state, batch_runner, gateway)
- static scan: every name any test imports directly from an edited
module still resolves
Plugin platforms (IRC, Teams, Google Chat) currently fail with
`No live adapter for platform '<name>'` when a `deliver=<plugin>` cron
job runs in a separate process from the gateway, even though the
platforms are eligible cron targets via `cron_deliver_env_var` (added
in #21306). Built-in platforms (Telegram, Discord, Slack, etc.) use
direct REST helpers in `tools/send_message_tool.py` so cron can deliver
without holding the gateway in the same process; plugin platforms
historically depended on `_gateway_runner_ref()` which returns `None`
out of process.
This change adds an optional `standalone_sender_fn` field to
`PlatformEntry` so plugins can register an ephemeral send path that
opens its own connection, sends, and closes without needing the live
adapter. The dispatch site in `_send_via_adapter` falls through to the
hook when the gateway runner is unavailable, with a descriptive error
when neither path applies. The hook is optional, so existing plugins
are unaffected.
Reference migrations land in the same change for IRC, Teams, and
Google Chat, exercising the hook across stdlib (asyncio + IRC protocol),
Bot Framework OAuth client_credentials, and Google service-account
flows respectively.
Security hardening on the new code paths:
* IRC: control-character stripping on chat_id and message body to
block CRLF command injection; bounded nick-collision retries; JOIN
before PRIVMSG so channels with the default `+n` mode accept the
delivery.
* Teams: TEAMS_SERVICE_URL validated against an allowlist of known
Bot Framework hosts (`smba.trafficmanager.net`,
`smba.infra.gov.teams.microsoft.us`) to block SSRF; chat_id and
tenant_id constrained to the documented Bot Framework character set;
per-request timeouts so a slow STS endpoint cannot starve the
activity POST.
* Google Chat: chat_id and thread_id validated against strict
resource-name regexes; service-account refresh wrapped in
`asyncio.wait_for` so a hung token endpoint cannot stall the
scheduler.
Test coverage: 20 new tests covering happy path, missing-config errors,
network failure modes, and each defensive validation. Existing tests
unchanged. `bash scripts/run_tests.sh tests/tools/test_send_message_tool.py
tests/gateway/test_irc_adapter.py tests/gateway/test_teams.py
tests/gateway/test_google_chat.py` reports 341 passed, 0 regressions.
Documentation: new "Out-of-process cron delivery" section in
website/docs/developer-guide/adding-platform-adapters.md and an entry
in gateway/platforms/ADDING_A_PLATFORM.md naming the hook.
The SDK requires Python >=3.12 so CI (3.11) falls to the except
ImportError branch, leaving TypingActivityInput=None. After loading
the adapter module, explicitly restore it from the mock so
test_send_typing doesn't silently no-op.

Adapted from PR #19188 by @LeonSGP43 — mocks cli_output helpers and
verifies interactive_setup persists credentials to .env without
crashing. Also adds megastary to AUTHOR_MAP.
Fixes the xdist collision that broke CI on PR #17764, and structurally
prevents future plugin-adapter tests from reintroducing it.
Problem
-------
tests/gateway/test_teams.py (new in this PR) and tests/gateway/test_irc_adapter.py
(already on main) both followed the same anti-pattern:
sys.path.insert(0, str(_REPO_ROOT / 'plugins' / 'platforms' / '<name>'))
from adapter import <Adapter>
Every platform plugin ships its own adapter.py, so the bare
'from adapter import ...' races for sys.modules['adapter']. Whichever test
collected first in a given xdist worker won; the other crashed at
collection with ImportError, and the polluted sys.path cascaded into 19
unrelated test failures across tools/, hermes_cli/, and run_agent/ in the
same worker.
Fix
---
1. tests/gateway/_plugin_adapter_loader.py (new): shared helper
load_plugin_adapter('<name>') that imports plugins/platforms/<name>/adapter.py
via importlib.util under the unique module name plugin_adapter_<name>.
Zero sys.path mutation, no possibility of collision.
2. tests/gateway/test_irc_adapter.py and tests/gateway/test_teams.py:
migrated to the helper. All 'from adapter import ...' statements
(including the ones inside test methods) are replaced with module-level
attribute access on the loaded module.
3. tests/gateway/conftest.py: new pytest_configure guard that AST-scans
every test_*.py under tests/gateway/ at session start and fails the
run with a pointer to the helper if any test uses sys.path.insert into
plugins/platforms/ OR a bare 'import adapter' / 'from adapter import'.
Runs on the xdist controller only (skipped in workers). The next plugin
adapter test that tries to reintroduce this pattern gets rejected at
collection time with a clear remediation message.
4. scripts/release.py: add aamirjawaid@microsoft.com -> heyitsaamir to
AUTHOR_MAP so the check-attribution workflow passes.
Validation
----------
scripts/run_tests.sh tests/gateway/ 4194 passed
scripts/run_tests.sh tests/gateway/test_{teams,irc}* 72 passed (both orderings)
scripts/run_tests.sh <11 prev-failing test files> 398 passed
Guard triggers correctly on both Path-operator and string-literal forms
of the anti-pattern.
Hello! I am the maintainer of the microsoft-teams-apps Python SDK and
I built this Teams adapter to integrate Microsoft Teams into Hermes.
Adds a `plugins/platforms/teams` platform plugin using the new
PlatformRegistry system from #17751. The adapter self-registers via
`register(ctx)` — no hardcoding in run.py, toolsets.py, or any
other core file.
Key features:
- Supports personal DMs, group chats, and channel posts
- Adaptive Card approval prompts with in-place button replacement
(Allow Once / Allow Session / Always Allow / Deny)
- aiohttp webhook server bridged from the Teams SDK to avoid
the fastapi/uvicorn dependency
- ConversationReference caching for correct proactive sends in
non-DM chats
- `interactive_setup()` for `hermes gateway setup` integration
- `platform_hint` for LLM context (Teams markdown subset)
- 34 tests covering adapter init, send, message handling, and
plugin registration
