feat(messaging): support Google Chat on Hermes over keyless Pub/Sub REST pull - #9393
Conversation
…EST pull Google Chat was the only messaging channel restricted to OpenClaw. Enable it for Hermes without placing the service-account key inside the sandbox. The bundled Hermes adapter receives Chat events over a gRPC Pub/Sub StreamingPull and signs its bot token in-process from that key. Neither survives in a sandbox. The OpenShell L7 protocol set has no gRPC variant, so the transport cannot be inspected, and raw relay would disable the very inspection the credential swap depends on. The adapter also offers no seam for a pre-minted token and hardcodes an httplib2 transport that cannot proxy HTTPS here. Rebind the bundled adapter to the transports a sandbox allows: pull the same subscription over the Pub/Sub REST API, and send replies through the L7 proxy carrying the gateway-minted placeholder. The rebind ships as a sibling plugin module that the plugin loads only when the channel is configured, so a Hermes sandbox without Google Chat never wraps the platform registry. Add the Hermes policy preset and provider profile for the channel, flip the managed-image platform lists, and cover the new render and gate paths in the existing messaging tests. Correct the DM allowlist prompt while it is in reach. It told every operator to enter users/NNN ids and stated that an email entry is ignored, which holds for OpenClaw but is inverted for Hermes, so a Hermes operator following it saved an allowlist that could never match. Filling the allowlist also switches the DM policy from pairing to allowlist, so a wrong-form entry drops the sender with no reply, no pairing code, and no log line at the default level. The prompt now names the form each agent expects, states that consequence, and points an operator who does not know their id at the pairing reply, which prints it on OpenClaw.
… route The Google Chat preset for Hermes allowed POST to every Pub/Sub v1 path, and the comment justified that width with a claim about glob matching that does not hold. The L7 matcher is glob.match(pattern, ["/"], path), so `/` is the only delimiter and `*` already spans the `:verb` suffix inside a segment. The adapter issues exactly two Pub/Sub requests, `:pull` and `:acknowledge`, so restrict the route to those. The gateway injects a bearer carrying the pubsub scope here, and the previous rule also permitted publish and subscription administration from inside the sandbox. Presets cannot template the configured subscription, so the rules match the subscription path shape. Drop the stale `:modifyAckDeadline` mention; the adapter never issues it.

The gateway proxy lookup opened every `/proc/<pid>/cmdline` it scanned without closing it. The Chat reply transport calls that lookup on every outbound request, so each reply leaked one descriptor per process on the host. Read the file under a context manager instead. Also drop the redundant `asyncio` import inside the reply transport; the module already imports asyncio at top level.

LOC Reduction / Codebase Simplicity Review
Why this blocks
The PR adds a 477-line repository-local fork of Hermes’s Google Chat behavior. It duplicates connect() at agents/hermes/plugin/googlechat_sandbox_adapter.py:200, rebinds four private methods at line 392, and wraps and mutates the global platform registry at line 428. A second activation path is hard-coded in agents/hermes/plugin/__init__.py:1442-1490.
That is 477 of 953 added lines, creates two owners for the Hermes adapter contract, and depends on private implementation details and deferred registration order. No Python or runtime test covers this layer; the PR text identifies the registry-order behavior as untested.
This also conflicts with src/lib/messaging/AGENTS.md:8-10 and src/lib/messaging/AGENTS.md:69-77, which place channel boot and connect shims under channel-owned manifest/runtime assets with behavior coverage.
Refactor direction
- Add or use a narrow, tested Hermes extension seam for transport and credentials that preserves the registered adapter metadata.
- Keep only the Pub/Sub REST pull and placeholder-auth delta in NemoClaw, selected through the Google Chat channel runtime.
- Remove the copied
connect(), globalplatform_registry.registerwrapper, private-method rebinding, and separate global-plugin channel gate. - If the pinned Hermes release lacks a stable seam, land that seam before presenting Hermes Google Chat as supported.
Expected result
One manifest-owned activation path, deterministic tests, and hundreds fewer lines. NemoClaw would maintain only its REST and credential delta instead of a parallel Hermes adapter implementation.
…es registry seams
The Hermes Google Chat delta was a repository-local fork: it copied the bundled
`connect()`, rebound four private methods onto each adapter instance, replaced
`platform_registry.register` for the whole process, and lived in the shared
Hermes plugin. Rework it to use the seams Hermes already publishes.
* `platform_registry.get("google_chat")` resolves the bundled entry and forces
its deferred loader, so the override no longer depends on registration order.
* `PlatformEntry` is a dataclass, so `dataclasses.replace` preserves every field
and changes only `adapter_factory`, `check_fn` and `required_env`.
`register()` documents last-writer-wins for exactly this case.
* The delta is now a subclass. Reporting no subscription from `_validate_config`
makes the bundled `connect()` skip its gRPC precheck, which is fatal under a
REST-only egress policy, and skip its own supervisor, so the copied `connect()`
is gone and the REST pull starts from the subclass instead.
* The module moves to `channels/googlechat/runtime/hermes-adapter.py`, the
channel-owned location `src/lib/messaging/AGENTS.md` specifies. The Hermes
image copies it beside the plugin, which still loads it only when the channel
is configured.
Three Hermes internals remain bound, because `PlatformEntry` carries no
credential or transport field and `adapter_factory` is its only injection point.
Pin them at image build instead: `image-build-probes.py
googlechat-override-seams` fails the build when one of those definitions moves,
rather than letting the channel fall back to the stock gRPC and service-account
adapter unnoticed. This follows the existing pinning practice for Hermes
internals in the same Dockerfile.
Behavior is unchanged: the same events arrive over the same Pub/Sub REST pull
and replies leave over the same proxied transport.
Also adds the two Hermes Google Chat config keys to the non-secret allowlist
test, which the channel needed and no run had exercised, and shortens the
comments this channel's files had accumulated.
… offline The capability-union layer installs every channel's Hermes packages with `--network=none` from a read-only wheel set, so the three Google Chat specs this branch added to the manifest had nothing to resolve against. uv failed with "google-cloud-pubsub was not found in the cache", which took the whole atomic install down with it, and the build surfaced that four steps later as a missing microsoft-teams-apps. Google Chat is the only channel whose Python dependencies Hermes does not package. The base image syncs `anthropic messaging web pty mcp`, and the `messaging` extra already carries telegram, discord, and slack, while WhatsApp runs through a Node bridge. Hermes declares no google_chat extra at all, and `_load_google_modules()` imports pubsub, googleapiclient, and grpc all-or-nothing even though this integration pulls Pub/Sub over REST. Vendor only the 18 packages the base venv lacks; uv satisfies the remaining 10 from the installed distributions, the same way the existing Teams wheels rely on fastapi and cryptography already being present. Only grpcio needs a per-architecture wheel.
The wheel set landed one package short: `google-cloud-pubsub` requires `opentelemetry-api>=1.27.0`, and the base venv does not carry it, so the offline union install still had nothing to resolve against. The first pass derived the missing set from a local Hermes checkout rather than the version the image pins. Recomputed against the exact `HERMES_VERSION=v2026.7.20` tarball, whose checksum matches `HERMES_TARBALL_SHA256`, with `agents/hermes/security-dependencies.patch` applied: 19 of the 28 packages are missing, not 18.
Nothing checked in exercised the adapter itself. The image-build probe pins upstream method names in the bundled source, and the runtime contract test covers the OpenClaw side, so a regression could have sent an unapproved request, replaced the credential placeholder, or dropped a message whose acknowledgement failed without any of it failing a check. Drive the real `_rest_pull` under `python3` against two doubles supplied on PYTHONPATH, one for aiohttp and one for the bundled Hermes adapter, and assert what crosses the wire: every request carries the placeholder bearer and nothing else, the only two URLs reached are `:pull` and `:acknowledge` on the configured subscription, a nacked message produces no acknowledge, and both acknowledgement failure modes leave the message to be redelivered instead of ending the pull loop. Each assertion was checked against a mutation of the adapter that it is meant to catch: a changed placeholder, `:acknowledge` swapped for `:modifyAckDeadline`, a rejected acknowledge breaking the loop, the transport error escaping its handler, and `nack()` acknowledging anyway.
…scaffolding The review this branch answers is a LOC and simplicity review, and the added surface still carried more explanation than it needed. Compress the module, class, and method docstrings to the facts a reader cannot derive from the code itself, and keep only the three that record a decision: why the L7 proxy set rules out gRPC, why the proxy URL comes from the gateway's /proc environ, and why httplib2 cannot carry the outbound call. Fold the sibling-module loader into the installer it serves, since the split bought only a second docstring. In the adapter test, replace the scripted if/elif chain with a scenario table, drop the unused branches of the aiohttp double, and merge the two cases that ran the same scenario twice. No behavior changes. Each of the five adapter mutations the test is meant to catch was replayed against the compressed test: a changed placeholder, `:acknowledge` swapped for `:modifyAckDeadline`, a rejected acknowledge breaking the loop, the transport error escaping its handler, and `nack()` acknowledging anyway.
…s policy Two behaviors this branch introduced had no regression guard. Both were found by live failures, and both would fail the same way again with every check green. The bridge minted its token from `scopes[0]` alone, which left Hermes with chat.bot but not pubsub and returned 403 on every `:pull`; the profile list was also filtered by channel only, so a channel shipping a profile per agent could configure the wrong one. Assert that one minted token carries every declared scope, and that only the profile matching the sandbox agent produces a bridge. The Hermes policy preset was narrowed from `/v1/**` to the two Pub/Sub operations the adapter issues, but nothing pinned it: widening it back would also permit publish and subscription administration. Pin the Pub/Sub and Chat rules, the reachable host set, and the absence of Pub/Sub egress for OpenClaw, which runs on an inbound webhook instead. Each assertion was replayed against the mutation it exists to catch: the agent filter removed, the scope list truncated to its first entry, the Pub/Sub rules widened to `/v1/**`, a third host added, and Chat writes opened beyond the spaces tree.

LOC Reduction / Codebase Simplicity Review
Resolved at 8c5e6c4c25b1d3ce02b97ec8f4fe2bc58edd3072.
The Google Chat delta now lives in the channel-owned runtime asset, subclasses the bundled adapter, calls the bundled connect(), and replaces only the published PlatformEntry fields through the documented registry seam. The global registry wrapper, copied connect implementation, instance method rebinding, and registration-order dependency are gone.
The remaining private Hermes method dependencies are explicit, image-build-pinned, and the REST pull, credential placeholder, allowed operations, acknowledgement behavior, and redelivery behavior now have deterministic runtime coverage.
No remaining blocking LOC or source-of-truth finding. This is a scope-limited follow-up, not an approval or a correctness, security, or CI review.
Resolved at 8c5e6c4; the copied Hermes adapter and global registry wrapper were removed.
The REST pull loop exits only on shutdown, so a second `connect()` on the same adapter without an intervening `disconnect()` would leave two consumers pulling one subscription and answering every message twice. Hermes v2026.7.20 builds a fresh adapter for each reconnect, so this holds the invariant rather than fixing a reachable path. Cancelling through the bundled `_supervisor_task` does not work here. On the no-subscription branch this override takes, `connect()` sets `self._supervisor_task = None`, so the handle no longer points at a running pull. Track the task on a subclass-owned `_sandbox_pull_task`, cancel and await that before starting a replacement, then bind both handles so the bundled `disconnect()` can still cancel the pull. The regression test mirrors that upstream assignment in its adapter double, drives the sequence on observed progress instead of fixed sleeps, and asserts the first task was cancelled and replaced, that the replacement is reachable through the bundled handle, and that one delivery is handled once. Two bridge call sites also mapped any unrecognized agent to OpenClaw, which would hand a sandbox no channel manifest supports the OpenClaw Google Chat bridge and its credential. Resolve the agent through `tryGetMessagingAgentId` instead, keeping the documented default that an unset agent is OpenClaw while a named unsupported one configures no bridge at all. Also suppress Ruff S105 on the resolver placeholder, matching the five BLE001 suppressions already in the file.

LOC Reduction / Codebase Simplicity Review
What remains resolved
The earlier adapter-fork finding remains resolved at 9cd2fcc598dd972a975bd9ec2dc5df5bf48f9531. The copied connect() implementation, global registry wrapper, private-method rebinding, and separate plugin-local adapter remain removed.
Why changes are requested
The latest PR commit adds 170 lines and deletes 30. Of that delta, src/lib/messaging/channels/googlechat/runtime/hermes-adapter.py:171,194-229 and its test add 97 net lines for a second pull-task handle and same-instance reconnect path.
_sandbox_pull_task and the bundled _supervisor_task now hold the same task. _stop_rest_pull exists because the bundled connect() clears its handle. However, the method documentation states that Hermes v2026.7.20 creates a fresh adapter for each reconnect. The new lifecycle authority and reconnect scenario therefore protect no current caller while expanding the private Hermes delta that the earlier refactor reduced.
The same commit also repeats agent selection at src/lib/actions/sandbox/policy-channel.ts:862-879 and src/lib/onboard/messaging-prep.ts:146-166. Both callers normalize the agent, consult a manifest registry, map an unset agent to OpenClaw, map an unsupported agent to no bridge, and then call collectMessagingBridgeTokenDefs. That collector already owns the bridge profiles and filters them by profile.agent at src/lib/onboard/messaging-bridge-provider.ts:260-279.
Refactor direction
- Remove the same-instance reconnect task state and reconnect-only test unless a current Hermes call path requires two
connect()calls on one adapter. - If that lifecycle is required, keep one task handle and show the reachable caller that needs replacement behavior.
- Let
collectMessagingBridgeTokenDefsown the unset-agent default and unmatched-agent result once. Pass the recorded agent from both callers and let the profile filter select or reject it.
Expected result
Keep the prior channel-owned adapter design, remove roughly 100 lines of unreachable reconnect scaffolding, and use one bridge-agent selection authority instead of two caller-specific branches.

Both failure branches sleep a fixed 3 seconds. A persistent failure, for example a 403 from the Pub/Sub policy or a proxy outage, produces a continuous warn-and-retry loop at 20 requests per minute for the life of the sandbox. Increase the delay on consecutive failures and reset it after a successful pull. Cap the delay at a small maximum so recovery stays fast.

Merge-train blocker: accepted product scope is required This PR creates a supported Google Chat integration for Hermes but does not link an accepted issue or design decision. The change adds 1,515 lines and removes 113 across 32 files, for a net increase of 1,402 lines. It also has four unresolved current review threads. The repository product-scope gate requires a maintainer decision that defines ownership, lifecycle, compatibility, security, and validation expectations before this can become canonical NemoClaw behavior. CI repair alone cannot supply that decision. Deferred for human direction. To resume the merge train, please link the accepted issue or design decision and confirm the intended release target. The current review findings and required checks must then pass on the resulting branch revision. No merge or close action is appropriate without that decision. |
Shaping a REST receivedMessage decodes its base64 payload, and that construction sat outside the per-message guard. A delivery whose data field cannot be decoded raised out of the loop, and nothing restarts the pull: connect() starts the task once, no callback observes it, and the platform keeps reporting itself connected because the bundled is_connected hook reads configuration only. Inbound would go quiet for the rest of the session. Guarding the construction alone would leave the poisoned delivery eligible for repeated redelivery until the subscription's own retention or dead-letter policy retired it, since redelivery cannot repair the same bytes and GOOGLE_CHAT_MAX_MESSAGES defaults to one per pull. The guard now acknowledges it, which is how the bundled handler retires an envelope it cannot parse. The handler branch is unchanged and synthesizes no acknowledgement, because the handler owns that policy and its failure can be transient. Neighbouring reads shared the defect and are covered now: the ack id, which raises on a receivedMessages entry that is not a mapping, and the envelope read, materialised inside the pull guard so that a 200 body which is not an object and a receivedMessages which is not iterable both become failed pulls that retry. The scripted aiohttp double signalled a refused connection through assert, which python -O strips. An inherited PYTHONOPTIMIZE turned that refusal into an ordinary non-200 response, so the acknowledge-transport scenario still observed two pulls and two handled messages with the production guard removed. Both checks now raise explicitly, and the refusal raises ConnectionError, which reaches the pull loop through the same clause a real proxy refusal would. One scenario carries all four malformed shapes, and reverting any single guard fails it. The transport scenario pins the double: it fails under PYTHONOPTIMIZE=1 when the acknowledge guard stops catching transport errors.
The Hermes portable build context walks every directory the Dockerfile copies and rejects a file that its reviewed manifest does not name, so the five files this branch adds under the Google Chat channel failed installer-integration on the first one it reached. Its Dockerfile parser also rejects a COPY that continues onto a second line, which the new plugin-asset COPY did. Join that instruction, name its source in the local COPY allowlist, and add the five files to the reviewed manifest. The parser and the reviewed manifest are the same two lists the gate compares, so both had to move together. installer-integration clones the pushed revision rather than the working tree, so this was verified by running the parser against the working tree and by the unit suite under src/lib/onboard/experimental, which builds its fixture from the manifest.

The PR still links no accepted issue or design decision, and the diff has grown to 1,568 additions and 113 deletions across 32 files, for a net increase of 1,455 lines. Technical review and CI remediation remain deferred until a maintainer records the supported Google Chat ownership, lifecycle, compatibility, security, and validation contract.

Live validation is recorded in the body, and a Google Chat E2E target needs a real GCP project, subscription and key. |
The appPrincipal walkthrough lived in the channel's enrollmentNotes, which `common.tokenPaste` prints for every agent right after the service-account key is saved. A Hermes operator therefore read a block that only applies to OpenClaw, ending in a `GOOGLECHAT_APP_PRINCIPAL=<N> ... channels add` and rebuild instruction that does nothing on a Pub/Sub pull deployment. The prompt itself was already correct: appPrincipal is collected by googlechat-openclaw-config-prompt, which is gated to OpenClaw, so Hermes was never asked for the value. Only the explanatory text leaked. Move it to prompt.help on the appPrincipal input, the same field allowFrom already uses for its multi-line guidance, so it renders where it is actionable and inherits the hook's agent gate. The Pub/Sub subscription prompt gains the binding operators miss most often, as four aligned lines rather than prose: which account needs roles/pubsub.publisher on the topic, where its address is shown, and what the failure looks like. A Chat app built with Interactive features publishes as the gcp-sa-gsuiteaddons service agent rather than chat-api-push@system, so granting Publisher only to the latter leaves the channel connected while no event reaches the subscription and Chat reports the bot as not responding. That was the last blocker in live setup, and nothing in the flow said so. This is prose and its placement, but it does change what onboarding prints: Hermes loses the appPrincipal block at the service-account step and gains two lines at the subscription step. Verified on a live Hermes onboard and by resolving the manifest: no enrollmentNotes remain, the guidance is 13 help lines on appPrincipal, and the Hermes-visible prompts are serviceAccount, allowFrom, projectId and subscriptionName. No test was added, since asserting manifest wording would be a source-shape test and that budget is zero.

Product-scope review after the #5492 reference I reviewed #5492 and #7317. #5492 is a design proposal with broad per-channel requirements, but it has no maintainer acceptance recorded for the Hermes Google Chat architecture. Its Hermes-specific reopening comment says the issue will track maintainer approval of that scope. Updating the channel table to “in progress” does not supply that approval. #7317 explicitly scoped the shipped Google Chat behavior to OpenClaw and described Hermes as a later follow-up with a different inbound and credential model. This PR introduces that different supported surface: Pub/Sub REST pull, a gateway-minted multi-scope token, a Hermes runtime override, added image dependencies, new lifecycle behavior, and a live-validation gap that needs real GCP resources. The product-scope gate therefore still needs a maintainer decision that accepts the Hermes design and names its ownership, compatibility, lifecycle, security, and release-validation expectations. The current +1,595/-130 change across 34 files is also flagged as large. Technical and CI work remains deferred because those choices can change the implementation and its required evidence. No merge or close action is appropriate until that human decision is recorded. |
|
Product scope clarification: Product Management approved Google Chat as a NemoClaw enterprise messaging channel for all supported agent runtimes, including Hermes. #7317 delivered OpenClaw first because OpenClaw and Hermes use different Google Chat protocols. This PR implements the Hermes portion of that approved scope. The decision is recorded in #5492: #5492 (comment). The existing #5492 acceptance criteria and repository review gates still apply. |
Resolved on the current commit. Issue #5492 is reopened and records Product Management approval for Google Chat across supported agents, including Hermes. Durable provider reuse now requires the selected agent profile ID and credential key, with agent-change and missing-secret coverage plus live managed-Hermes evidence.

Issue #5492 now records Product Management approval for first-class Google Chat across supported agent runtimes, including Hermes. The implementation keeps service-account material gateway-side, restricts egress to Chat and Pub/Sub operations, binds durable reuse to the selected agent profile and credential key, and records managed-Hermes live validation.

Summary
Google Chat was the only messaging channel restricted to OpenClaw. This change enables it for Hermes without placing the service-account key inside the sandbox: Hermes pulls Chat events from the configured Pub/Sub subscription over the REST API and replies through the OpenShell L7 proxy with a gateway-minted bearer, so the sandbox only ever holds a credential placeholder. Before,
channels add googlechatwas refused on a Hermes sandbox; after, the channel enrolls, receives DMs, and replies.Related Issue
Completes the Hermes half of #5492 for Google Chat. That issue models support per agent and states a channel needs to work for each runtime whose upstream actually supports it; Hermes
v2026.7.20shipsplugins/platforms/google_chat/adapter.py, so Hermes is inside its accepted scope. #7317 delivered the OpenClaw half and the issue was closed with that half done. It is reopened, and its channel table now records this PR against the Google Chat row. Not a closing reference, since the issue tracks the whole channel catalogue. Release target: next patch release.Changes
channels/googlechat/policy/hermes.yaml: Pub/Sub REST pull for inbound and Chat REST for the reply, restricted to the two Pub/Sub operations the adapter issues (:pull,:acknowledge) and to the Chatspacestree for writes.channels/googlechat/provider-profile/hermes.yaml: one gateway-minted token coveringchat.botandpubsub, with the service-account private key designated as gateway-side secret material.channels/googlechat/manifest.ts: allow Hermes, add the Hermes-only project and subscription inputs, render the Hermes env and platform fragment, and declare thegoogle-*packages the managed image needs.google_chatfrom the managed-image neutral list to the Hermes supported list, and let the bridge-provider collector select a profile by agent.channels/googlechat/runtime/hermes-adapter.py: a channel-owned runtime asset that subclasses the bundled Google Chat adapter for a Pub/Sub REST pull loop, placeholder credentials, and an aiohttp reply transport, and attaches it throughplatform_registry.get()plusdataclasses.replace().users/NNNids and claimed emails are ignored. That holds for OpenClaw and is inverted for Hermes, and the prompt did not say that filling the allowlist switches the DM policy from pairing to allowlist, so a wrong-form entry drops the sender with no reply and no pairing code.Why the module load is conditional. Hermes loads only
__init__.pyas the plugin entry, so the gate inagents/hermes/plugin/__init__.pyloads the sibling channel asset by path when the renderedGOOGLE_CHAT_SUBSCRIPTION_NAMEis present. Nothing else reads the module, and the registry entry is replaced throughplatform_registry.get()anddataclasses.replace()rather than a globalregisterwrapper. A failed load logs and returns without aborting plugin registration. The gate itself has no automated test, for the reason recorded under Quality Gates.Type of Change
Quality Gates
Coverage gap. The override itself is covered:
channels/googlechat/runtime/hermes-adapter.test.tsdrives the real pull loop underpython3, andchannels/googlechat/policy.test.tspins the egress preset. What has no automated coverage is the load gate inagents/hermes/plugin/__init__.py, because this repository runs no CI lane for Python tests underagents/hermes/plugin/, so a unit test placed there would gate nothing. The risk it would guard against is a runtime property, that the gate stops firing and Hermes silently keeps the stock gRPC and service-account adapter, which the REST-only policy then blocks. The nearest real coverage is thehermes-e2elane. Live validation is recorded under Verification.DGX Station Hardware Evidence
