Document the actual transport split: legacy editable drafts by default, optional rich drafts, persistent rich final sends, and in-place rich final edits for edit-based streams.
- matrix/dingtalk: extract deps-only installers (ensure_matrix_deps,
ensure_dingtalk_deps) and register THOSE as ensure_deps_fn — the prior
check_*_requirements combined credential env checks with the install,
so a platform configured via PlatformConfig.extra (which is_connected
accepts) would pass enablement, reach create_adapter(), and have the
'installer' veto on env-var grounds before installing anything —
re-creating the #79812 deadlock for extra-configured setups. The
combined deps+credentials functions remain for setup/status callers.
- matrix/feishu passive probes: use the existing lazy_deps.is_available()
instead of hand-rolling 'not feature_missing(...)' (reuse finding).
- teams: module docstring no longer recommends bare system pip (the
PEP 668 trap purged everywhere else); docs troubleshooting row updated
to match the new hint text.
- wecom_callback: drop dead 'global ET, DEFUSEDXML_AVAILABLE'
(ensure_and_bind mutates the module dict directly; nothing assigns).
- tests: parametrized wiring contract for all 8 lazy-installable
platforms — ensure_deps_fn present and distinct from check_fn
(behavior contract, not identity snapshot, so renames don't churn it).
- 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).
The reset keywords have existed in both CLI and gateway handlers since
June but were undocumented — users couldn't find how to cancel a
personality overlay. Adds a 'Resetting to the default' section to the
personality feature page and mentions the reset in the CLI guide,
slash-command reference (both tables), and messaging command table.
- New website/docs/user-guide/messaging/a2a.md: when/where to use A2A
(cross-machine, specialist peers, being callable) vs delegation/kanban
for same-machine multi-agent; enable, outbound tools, inbound surface,
security model, env reference, quick test, troubleshooting. Registered
in sidebars.ts and the messaging index.
- README/DESIGN/plugin.yaml/protocol.py prose updated to name the A2A
v1.0 canonical discovery path /.well-known/agent-card.json (the code
already served both; only the docs lagged).
Builds on the adapter list_channels() hook (cherry-picked from #43545 by
@Guoen0):
- plugins/platforms/simplex: implement list_channels() — enumerates
contacts (/contacts) and groups (/groups) over the live daemon
WebSocket into the channel directory. Returns None when the WS is
down so the directory falls back to session discovery instead of
wiping known targets.
- hermes send --list: merge configured-but-undiscovered platforms into
the listing. Previously a platform configured only via env (e.g. a
fresh SimpleX setup used for outbound sends) was silently omitted,
leaving users guessing at platform names.
- format_directory_for_display(): accept an explicit platforms view and
render empty platforms with a targeting hint instead of hiding them.
- docs: simplex hermes-send section.
Reported by Fedpostoffice on Discord (simplex missing from
hermes send --list; guessed platform names simplex-chat/simplex-relay).
Google API and authentication packages permit vulnerable httplib2 and pyasn1
transitives, while the Workspace and Google Chat runtime installers previously
treated any importable version as sufficient. Existing environments could
therefore remain vulnerable after the project dependency pins were repaired.
Carry the fixed versions through the Google and Vertex extras, lazy feature
requirements, lockfile, and both runtime installers. Route the documented
Google Chat installation path through its maintained secure requirements
instead of an unconstrained direct pip command.
Detect stale distributions, install only unsatisfied requirements, and verify
the result before continuing. Behavioral tests cover those repair invariants
without freezing manifests, lockfiles, or complete package sets.

LINE plugin.yaml plus line/wecom-callback/msgraph-webhook/
whatsapp-cloud/teams user-guide pages still documented the old
IPv4-only 0.0.0.0 defaults; update to the dual-stack unset default.
Telegram webhook env docs live in the adapter docstring (updated with
the code change); its plugin.yaml has no webhook host entry.
Consolidates the native-transport half of PR #73636 by @ScaleLeanChris
onto the merged adapter: persistent NIP-42-authenticated Nostr WebSocket
subscription as the default inbound path (transport=auto|websocket|poll),
kind-44100 membership events for live DM discovery, since-timestamp
resume on reconnect with bounded exponential backoff, and automatic
fallback to CLI polling when the WS can't be established. Events route
through the same _handle_event() pipeline as the poll loop, so de-dupe,
mention gating, p-tag DM latching, and allow-lists behave identically on
both transports. Outbound stays on the CLI (one-shot sends never race a
WS auth handshake — his design).
E2E verified against a real in-process websockets relay: NIP-42
challenge -> signed kind-22242 AUTH (event id re-derived server-side) ->

The sidecar auth token is generated at spawn (secrets.token_hex) and
existed only in the gateway process memory + sidecar child env, so
_standalone_send from cron subprocesses, hermes send, or the dashboard
structurally could not authenticate (#69960).
The adapter now writes <hermes-home>/runtime/photon-sidecar.json
({port, token, pid}, 0600, atomic tempfile+os.replace) once the sidecar
passes its /healthz readiness check, and deletes it in _stop_sidecar,
on every startup-failure path, and at disconnect so a stale record
never outlives a dead sidecar. _standalone_send falls back to the
record when PHOTON_SIDECAR_TOKEN is unset, validating the recorded pid
is alive first; a stale record yields a clear 'gateway appears to be
down' error. Docs note the gateway-must-be-running requirement and the
Photon-side shared-line initiation policy (#51897).
Expands the 'Recommended display settings' section into a comprehensive
'Recommended default settings' block covering display, access control,
polling, and mention behavior. Each setting includes an inline annotation
and rationale bullet. Matches Telegram/email default behavior (no
intermediate tool output, mention-gated channels, private-by-default
access).

Plugin-path adapter (zero core changes) connecting Hermes to a Buzz
community relay via the buzz CLI binary (JSON in/out, arg-list exec,
key passed via env only). Inbound uses a poll loop with per-channel
high-water marks seeded from newest (no history replay), event-id
de-dupe, self-echo suppression by pubkey, and mention gating in
channels (DMs always dispatch). Registers env_enablement, cron
home-channel delivery, and an out-of-process standalone sender,
mirroring the IRC plugin.
Verified against a live relay: connect -> send -> poll -> MessageEvent
round-trip, self-echo suppressed, clean disconnect.
Known limitation: polled inbound (default 4s); a websocket transport
(buzz-ws-client) is a future optimization.

- Change await self._send_read_receipt to asyncio.create_task to avoid
blocking message dispatch on slow bridge responses (matches BlueBubbles
pattern). Up to 5s per-message latency eliminated.
- Update tests: assert_called_once_with instead of assert_awaited_once_with
since the receipt is now scheduled, not directly awaited.
- Add send_read_receipts documentation to whatsapp.md following the
BlueBubbles docs pattern.
Renaming a Telegram bot's @username in BotFather silently stopped the
gateway from answering in groups.
PTB caches getMe() in Bot._bot_user and only rewrites it inside get_me(),
so after a rename the adapter kept comparing mentions against the OLD
handle. The exclusive-mention gate then saw the new @handle, failed to
match itself, and concluded the message was addressed to a different bot
— dropping it before the reply and wake-word fallbacks could run. Native
replies to the bot were discarded too. Polling mode recovered on the next
90s heartbeat; webhook mode never calls get_me() again, so it stayed dead
until restart.
Separately, the bot-handle pattern assumed every bot username ends in
"bot". Collectible (Fragment) usernames can be assigned to bots and drop
that suffix (@jarvis, @pic), so such a bot could not recognise its own
handle in the entity-less fallback and was suppressed by any message that
also named another bot.
- Route every mention comparison through _current_bot_username(), which
prefers the last observed handle over PTB's cache.
- Learn the live handle from inbound updates: Telegram stamps the current
username on our own messages and on reply_to_message. Guarded by user
id, so another account's handle is never adopted.
- Re-check identity out of band (TTL-bounded, one getMe per 5 min) when
the exclusive gate is about to drop a message — the exact stale-handle
symptom — so the mistake self-corrects instead of persisting.
- Refresh identity in webhook mode via a dedicated low-frequency loop,
cancelled on the same teardown fence as the heartbeat.
- Match our own handle by identity rather than shape. Foreign handles keep
the deliberate "...bot" narrowing so human @handles still never act as
routing hints (the intent behind ce4d857021).
Validation: 11 regression tests; sabotage runs confirm each behavioral
test fails with the fix reverted. 157 tests green across the Telegram
gating, reconnect, and topic-mode suites.
Add --long-description / --long-description-file to `hermes slack
manifest` so the generated app manifest can carry Slack's
display_information.long_description (175–4,000 characters), with
validation of the length bounds, mutual-exclusion with --slashes-only,
and UTF-8 file input. Also propagate the manifest command's exit status
through cmd_slack so validation failures reach the shell.

on this salvage branch.
Salvaged from #65256
Build the full reaction pipeline on top of the #29916 base:
- Opt-in gate: slack.reaction_triggers (default OFF — reaction events
stay acked-and-dropped so busy channels don't wake the agent on every
emoji). 'true' routes reactions on the bot's OWN messages; an explicit
emoji-name list routes those emojis from any message (handoff flows).
- reaction_removed events now route too, distinguished by the
cross-platform text convention reaction:added:<emoji> /
reaction:removed:<emoji> (matches the Feishu and Photon adapters, so
agents and skills see one shape everywhere).
- Authorization: the reactor becomes the synthesized message's user, so
the early _is_user_authorized gate and allowed_channels whitelist
apply exactly as for typed messages. _hermes_force_process only skips
the mention requirement (a reaction on the bot's own message is
definitionally addressed to the bot), mirroring Feishu/Photon.
- Gateway hooks (#33111 by @johnkattenhorn): every human reaction on a
message item fires reaction:added / reaction:removed through the new
BasePlatformAdapter.set_reaction_handler → GatewayRunner
._handle_reaction_event → HookRegistry.emit, independent of the
routing opt-in. Documented in hooks.md.
- Channel handoff (#45265 by @Kev-fs): slack.reaction_trigger_target
routes the reaction turn to a configured channel (top-level via
_hermes_no_thread_response + reply-anchor suppression in
gateway/platforms/base.py) or C123:<ts> thread.
- Manifest: reaction_removed event subscription added alongside
reaction_added/reactions:read.
- Docs: slack.md Reaction Triggers section; hooks.md event table rows.

Documents user-facing wave-1+2 Slack behavior that had no docs coverage:
- decision table for require_mention / free_response_channels /
require_mention_channels / thread_require_mention / strict_mention /
ignore_other_user_mentions and how they compose
- 'Accepting messages from other bots' section with the post-#69483
semantics: allow_bots=mentions requires a CURRENT mention from
peer bots (text or Block Kit blocks); thread state never admits them
- clarify one-tap buttons (choice buttons + Other free-text mode,
in-place resolution, double-click guard, expiry message)
- slash replies are ephemeral: replace-ack, chunking, 5-post cap with
explicit truncation notice, postEphemeral fallback, never-public rule
- cron deliver targeting (slack -> home channel, slack:C... channel,
slack:U... resolved to DM) incl. standalone sender + MEDIA uploads
- send_message media + bare-user-ID DM resolution and caption behavior
Refs #26184.
- Add SLACK_THREAD_REQUIRE_MENTION, SLACK_IGNORE_OTHER_USER_MENTIONS and
SLACK_REQUIRE_MENTION_CHANNELS to the conftest behavioral-env force-clear
list so config-loader side effects can't leak between tests (same class
of leak the existing SLACK_* entries guard against).
- Document thread_require_mention and require_mention_channels in the
Slack messaging guide next to the other mention-gating options.
Adds the option to the Mention & Trigger Behavior section: leading-
mention semantics, opt-in default, env var, and DM/MPIM scope (1:1 DMs
unaffected; MPIMs apply it like channels).

Update the CLI and messaging guides so the default `interrupt` mode reflects
the new behavior: a follow-up redirects the active turn (preserving displayed
reasoning and completed work, letting running tools finish at a safe boundary)
rather than hard-stopping it, with `/stop` still the explicit hard stop.
Follow-up to the salvaged #52552 and #53083 commits:
- Rework the Matrix PLATFORM_HINTS entry around what the adapter actually
emits: headings, numbered lists, blockquotes, strikethrough-free markdown
all render (the adapter converts them to sanctioned HTML). Keep the
genuinely valuable guidance: no Markdown tables (Element X / Beeper /
mobile clients don't render HTML tables — cells collapse into one line),
no spoilers/checkboxes/~~strikethrough~~ (not converted by
python-markdown), prefer descriptive link text.
- Regression test: hint must steer models away from tables.
- Fix test_long_response_split_preserves_thread_context to derive its
payload size from the adapter's configurable limit instead of assuming
the old hardcoded 4000.
- Document matrix.max_message_length in the Matrix docs page.
- Contributor mapping for RKelln.
The DingTalk docs offer gateway.platforms.dingtalk.extra.allowed_users
as the config.yaml alternative to DINGTALK_ALLOWED_USERS. The adapter
honors it (_load_allowed_users reads PlatformConfig.extra), but gateway
authorization (_is_user_authorized in gateway/authz_mixin.py) only
consults the env var, and load_gateway_config() bridged the allowlist
to the env var only from a top-level dingtalk: block. A nested-only
allowlist therefore passed the adapter and was then denied at the
gateway - listed users fell through to pairing/default-deny in DMs.
Extend the DingTalk YAML->env bridge to fall back to the merged nested
platform config (gateway.platforms / platforms), mirroring the existing
platforms.discord.extra.allow_from precedent. Precedence is unchanged:
an explicit DINGTALK_ALLOWED_USERS env var still wins, then the
top-level dingtalk: block, then the nested extra.
Also correct the docs' claim that the two allowlists are "merged" when
both are set - that behavior never existed (the doc line came from a
docs-only sweep); the effective result is the intersection of the two
gates, so the docs now recommend configuring one or the other.
Repro (before): config.yaml containing only the nested allowlist ->
adapter._is_user_allowed("user-id-1") is True but
runner._is_user_authorized(...) is False. After: both True; unlisted
users are still denied.

A final response generated but not confirmed-delivered was the one
artifact the gateway could lose without a trace: crash or planned
restart between finalize and platform ACK dropped it silently, and the
resume path re-ran the whole turn at full cost (#58818 P1, #41696,
#63695's gateway half).
gateway/delivery_ledger.py records each outbound final response in
state.db (same conventions as the async-delegation ledger: WAL, owner
pid + process-start-time liveness, bounded retention):
pending -> attempting -> delivered | failed
startup sweep on dead-owner rows -> redeliver | abandoned
Contract (the lessons from the closed delivery-outbox attempt #61790):
- obligation recorded BEFORE the first send attempt; cleared only on
SendResult.success (destination acceptance, #51184)
- ambiguity is labeled, never silently retried: rows that were mid-send
when the process died redeliver with a visible '♻️ Recovered reply —
may be a duplicate' prefix (honest at-least-once)
- stable ids from session_key + inbound message id + content, so
distinct threads/topics can never collide
- poison rows bounded: 3 attempts / 24h freshness -> abandoned; claim
atomically re-stamps ownership so racing sweeps can't double-claim
- redelivery clears resume_pending for the session so the resume path
never re-runs a turn whose answer the ledger already holds
- best-effort everywhere: ledger failure can never block or delay a send
- slash-command/ephemeral/empty responses are not recorded; cron and
proactive delivery stay on DeliveryRouter (separate subsystem)
Config: gateway.delivery_ledger (default on; no version bump needed).
Validation: 30 ledger+producer tests; 352 blast-radius gateway tests
green; cross-process E2E (record in process A, kill it mid-send, claim
+ marker + redeliver in a fresh process B against the same state.db).
Route recovered messages through the live Discord ingress policy, preserve dedup and completion invariants, bound and retain the recovery ledger, and expose the opt-in config with docs and backup coverage.
Builds on the salvaged typing_status_text plumbing (PR #62007): instead
of a static 'is thinking...', Slack's assistant status line now updates
live as the agent works — 'is running pytest tests/…', 'is reading
docs/api.md…' — and reverts to the static text between tool calls.
Mechanics:
- agent/display.py: build_status_phrase() derives a <=49-char present-
tense phrase from the existing _TOOL_VERBS table (+ 'is using <name>'
for plugin/MCP tools; None for _thinking).
- base adapter: supports_status_text capability flag + set_status_text()
per-chat store, cleared when the typing loop winds down.
- Slack adapter: send_typing() renders the live phrase when set, falling
back to typing_status_text then 'is thinking...'.
- gateway/run.py: progress_callback stashes the phrase on tool.started
and clears on tool.completed. Rendering rides the existing
_keep_typing refresh cadence — zero additional Slack API calls, no
rate-limit exposure. Works with tool_progress: off (Slack default);
the callback is now armed whenever the adapter supports status text.
- display.live_status config (full|verb|off, default full): 'verb' hides
argument previews for shared/customer-facing channels.
Also fixes a latent crash in the cherry-picked from_dict: malformed
non-dict 'extra' sections broke typing_status_text resolution (uses the
already-coerced extra dict).
Design notes: status text is a side-effect display channel only — never
enters the transcript, no prompt-cache impact. Lifecycle guarantees from
the stuck-status fix family are preserved (per-thread tracking,
clear-on-finish via existing stop_typing paths). Related: #45109
(closed; same direction via lifecycle states), #59010/#51363 (native
task cards — complementary, larger scope).
Adds PlatformConfig.typing_status_text for the two platforms that render
text for the working-state line: Slack's assistant.threads.setStatus
status (hardcoded 'is thinking...') and Google Chat's visible marker
message (hardcoded 'Hermes is thinking…'). None keeps each platform's
built-in default; to_dict omits the field when unset so existing configs
serialize unchanged. Plumbing mirrors typing_indicator exactly (typed
field, from_dict extra fallback, shared-key bridge).
Also documents that Slack's status line requires the assistant:write
scope — without it setStatus fails silently and Slack shows its own
generic placeholder, which previously made the behaviour undiagnosable
from config alone.
Replace REST-based Discord liveness probe with local WebSocket/heartbeat
state detection. REST success doesn't prove Gateway event delivery — a
half-closed WebSocket can leave Bot.start() alive while REST returns 200.
Now samples ready/open/ACK state and heartbeat latency; consecutive
unhealthy samples emit one retryable fatal code so GatewayRunner rebuilds
the adapter through the existing reconnect path.
Also fixes three lifecycle gaps in the recovery path:
1. asyncio.wait_for() can remain blocked if adapter cleanup swallows
cancellation — now uses bounded asyncio.wait() with task detachment.
2. Multiplexed secondary-profile adapters had no profile-scoped reconnect
owner — now uses one runner-owned reconnect slot per profile.
3. An in-flight turn could send its final text through the disconnected
adapter after a replacement was registered — now resolves the live
same-profile replacement for unsent final responses only (message IDs
never migrate, edits/deletes stay on the old transport).
Adds an opt-in Linux/systemd event-loop watchdog (gateway.systemd_watchdog_seconds,
default 0) for the failure mode where the whole asyncio loop stops making
progress and no in-process liveness task can run. stdlib-only sd_notify,
Type=notify/WatchdogSec generation, READY/STOPPING lifecycle.

OpenAI lets ChatGPT-plan Codex users bank rate-limit reset credits, but
until now they could only be redeemed from the Codex CLI/app or the
website. This wires the same backend API into Hermes:
- /usage on the openai-codex provider now shows "You have N resets
banked - use /usage reset to activate" (parsed from the
rate_limit_reset_credits field the /usage endpoint already returns).
- New /usage reset subcommand (CLI + gateway) redeems one banked
credit via POST .../rate-limit-reset-credits/consume with a UUID
idempotency key, mirroring codex-rs backend-client semantics
(PathStyle /wham vs /api/codex, ChatGPT-Account-Id header,
reset/nothing_to_reset/no_credit/already_redeemed outcomes).
- Guard: redemption is refused while no rate-limit window is fully
exhausted, since a banked reset restores the FULL 5h + weekly
allowance and spending it early wastes it. /usage reset --force
overrides. Zero banked credits and non-codex providers are refused
with clear messages; nothing_to_reset reports the credit was NOT
spent.
- i18n: new gateway.usage.unknown_subcommand / reset_wrong_provider
keys across all 16 locales; docs updated (cli.md, messaging index).
Tested with unit tests plus a real-socket E2E against a local fake

Sessions no longer auto-reset by default. SessionResetPolicy.mode now
defaults to "none" (was "both": 24h idle + daily 4am), matching the
setup wizard's existing no-reset default and community feedback that
surprise context loss hurts more than it helps.
- gateway/config.py: dataclass default + from_dict fallback -> "none";
installs whose config.yaml lacks a session_reset section stop
auto-resetting
- hermes_cli/setup.py: "Never auto-reset" is now the recommended/default
choice in hermes setup agent; stale comment updated
- docs (en + zh-Hans): default is no auto-reset, opt in via
session_reset in config.yaml
Users who explicitly configured idle/daily/both resets keep them.
Add an opt-in toggle (require_admin_for_exec_approval, default false) that
restricts who can click Approve/Deny on a dangerous-command prompt to admins
listed in allow_admin_from. Off by default, so the v0.16-restored user-scope
behavior is unchanged. When on, the clicker must pass the normal admission
check AND be an admin; fails closed (logged) when no admins are configured.
Only ExecApprovalView is gated — model picker / clarify / update-prompt stay
user-scope.

Follow-ups for salvaged #58461.
Group DMs (MPIMs) were classified as DMs and thereby exempted from every
operator control that shared surfaces are supposed to honor: allowed_channels,
require_mention, strict_mention, free_response_channels, and the reaction
guard. Symptom: the bot added 👀/✅ to unmentioned MPIM
messages and still invoked the agent (which then returned NO_REPLY) instead of
the gateway dropping the event before model execution. Removing an MPIM from
allowed_channels did not disable it.
Root cause is the DM classification at adapter.py:
is_dm = channel_type in {"im", "mpim"}
used for BOTH routing exemptions and reaction gating. An MPIM is a shared
surface (multiple humans can see and trigger the bot), not a private 1:1 DM,
so it must be gated like a channel.
This behavior was introduced/reinforced by a trail of Slack group-DM PRs:
- #4633 fix(slack): treat group DMs (mpim) like DMs + reaction guard
- #54632 fix(slack): subscribe to message.mpim + mpim scopes so group DMs work
- #54663 fix(slack): group DMs work OOTB + reinstall nudge
#54632/#54663 correctly made MPIM messages *reachable*; #4633 over-reached by
giving them the DM mention/reaction *exemptions*. This corrects only that
over-reach.
Fix (minimal): introduce `is_one_to_one_dm = channel_type == "im"` and key the
two EXEMPTION sites off it instead of `is_dm`:
- mention/allowlist gating block (`if not is_one_to_one_dm and bot_uid:`)
- reaction guard (`(is_one_to_one_dm or is_mentioned)`)
`is_dm` is intentionally retained for session/thread scoping and chat_type
labeling, where treating an MPIM as a persistent multi-party conversation is
correct — only the mention/reaction exemptions were wrong.
Docs: slack.md now distinguishes 1:1 DMs (mention-exempt) from group DMs
(shared surface; obey require_mention/strict_mention/allowed_channels/
free_response_channels; reactions only when @mentioned).
Tests: +7 in test_slack_mention.py (MPIM unmentioned dropped under
require_mention and strict_mention; MPIM mentioned processed; MPIM off
allowed_channels dropped; MPIM in free_response opted in; 1:1 IM still exempt;
reaction guard drops unmentioned MPIM). Updated _would_process to model the
is_one_to_one_dm gating + strict_mention. 72 passed.
