HOOK_SPAWN_CMD includes the jq executable required by the watch_config lookup.
Update the PATH construction in the relevant agent-box configuration to include
pkgs.jq, or configure JQ with its absolute executable path, while preserving the
existing lookup and fallback behavior.
- Around line 216-217: Update the hook profile selection in webhook-spawn.sh so
a rejected or missing watch profile does not overwrite the previously loaded
box-wide AGENT_BOX_HOOK_PROFILE. Keep the box-wide value separate from the
watch-specific assignment around the hook_profile and hook_profile_source logic,
restore it when the watch profile is ignored, and validate the restored profile
before launch so delivery continues with the valid box-wide default instead of
falling back to the agent default.

- Around line 447-448: Update the watch_profile extraction in the agent-box
webhook spawn script to accept profile only when the JSON value is a string;
non-string values, missing profiles, and invalid watch configuration must yield
an empty value so the box default is used.

Three from CodeRabbit on #488, all real. **jq was not on the settings daemon's PATH.** --preamble has two callers and they do not share a PATH: the receiver unit's has jq, and the settings unit FORCES one of the daemon, coreutils, findutils, gnugrep, gnused and systemd.

The rebase kept the 0.25.0 prose while taking master's 0.26.0 pin, so both release paragraphs claimed to be "this pin". The 0.26.0 one is right — the pinned webhook.py declares 0.26.0 — so the 0.25.0 paragraph keeps its issue reference and gives up the claim. CodeRabbit on PR #488.

The last open step of #321. AGENT_BOX_HOOK_PROFILE picks ONE worker for every dispatched hook-* session on the box. What it cannot say is "cheap triage for new issues, something that can actually fix things for a red build" — the spawn wrapper could not tell two watches on one repo apart, because every LOCAL_WEBHOOK_SPAWN_* variable it receives describes the EVENT, not the watch that matched it. local-webhook 0.25.0 (defangdevs/local-channels#51, this pin) adds the one that does: LOCAL_WEBHOOK_SPAWN_CONFIG, an opaque map carried on the subscription. So: agent-box-webhook subscribe OWNER/REPO --deliver-to subagent \ --when '{"any":[{"path":"action","in":["opened"]}]}' \ --profile cheap-triage - agent-box-webhook subscribe --profile NAME translates to webhook.py's --spawn-config profile=NAME, the same way --claim translates to --include. --profile= clears it on a re-subscribe. Refused on a session subscription (it spawns nothing) and on a name that could escape into a file path; a profile that does not exist YET is only a warning, because subscribing before creating it is a legitimate order to do things in. - webhook-spawn.sh takes the watch's profile over both box-wide settings, and validates it exactly as before: an unusable name is reported and ignored, never a dropped delivery. - --preamble has no delivery, so it reads the watch out of filter.dispatch.json instead. The settings panel prints that preamble, and a panel naming the box-wide worker for a watch that overrides it would be a lie the operator only discovers from a session that already started (#292). The daemon now passes the state dir and stamps that file into the preamble cache key, so a re-subscribe re-renders. - webhook-policy-apply.sh leaves spawnConfig alone, so --profile survives a receiver restart on a governed watch. Deliberate, and now said in the comment: a profile is runtime data, which is why AGENT_BOX_HOOK_PROFILE has no NixOS option beside it either. Checks: all 24 aarch64 flake checks green (module-generated-up-to-date, golden-snapshot, backend-parity, one-spec-both-backends, webhook-route, webhook-claim, webhook-panel-state, profile-panel, runtime-profile, ...) plus python3 tests/test_agentbox.py (77). tests/webhook.nix gains ~150 lines: the CLI writing spawnConfig.profile and it coming back out of `ls`, the watch beating the box-wide setting, an entry with no profile still falling back to it, --preamble naming each, --profile= clearing, and both refusals. That file is x86-only here, so it was eval-checked (drvPath) and its testScript extracted, compiled and ruff-linted. Behaviour also driven against the real built wrappers on this box, which is where the failure paths were confirmed: a garbage LOCAL_WEBHOOK_SPAWN_CONFIG, a corrupt dispatch file, a missing profile and a "../escape" name all fall back to the box default and say so.

backend-parity caught what my local run did not: e9bb009 pinned jq in the module's webhookSpawn derivation only, so a native box's webhook-spawn.sh still resolved a bare `jq` — and its --preamble caller, the settings daemon, is exactly the PATH that does not have one. Native pins it in the /etc/agent-box/bin/agent-box-webhook-spawn wrapper it already generates for the same purpose (issue #471's hook_env), from the runtime profile that ships jq. My "all 24 checks green" on the previous commit was wrong, and worth recording why: the run was `nix build ... 2>&1 | tail -3; echo $?`, so the status reported was tail's, not nix's. Re-run without the pipe: NIX_BUILD_RC=0 over all 24, plus 77 native tests.

This commit used to also move the local-channels pin onto the 0.25.0 merge commit. master has since pinned 0.26.0 (789b374), which contains that merge, so the rebase drops the pin hunk and keeps only the prose it carried. The behaviour the prose describes is unchanged and still worth stating in the `rev` option's description: dispatch batches queue per (key, spawnConfig) rather than per key, so two watches on one repo cannot coalesce into a single spawn that hands one watch's events to the other's worker.

The rebase kept the 0.25.0 prose while taking master's 0.26.0 pin, so both release paragraphs claimed to be "this pin". The 0.26.0 one is right — the pinned webhook.py declares 0.26.0 — so the 0.25.0 paragraph keeps its issue reference and gives up the claim. CodeRabbit on PR #488.

Closes #321. Companion to defangdevs/local-channels#51 — merge that first, then re-pin (see Before merging).
The gap
AGENT_BOX_HOOK_PROFILEpicks one worker for every dispatchedhook-*session on the box. It cannot say "cheap triage for new issues, something that can actually fix things for a red build", becausewebhook-spawn.shcould not tell two watches on one repo apart: everyLOCAL_WEBHOOK_SPAWN_*variable it receives describes the event, not the watch that matched it.That is the one step of #321 that has been open since #337 shipped steps 2–4 on 2026-08-23. local-webhook 0.25.0 adds the missing variable,
LOCAL_WEBHOOK_SPAWN_CONFIG— an opaque map carried on the subscription — so this is the consumer side of it.What you can now do
agent-box-webhook lsshows it.--profile=clears it on a re-subscribe.The changes
webhook-cli.sh—--profile NAMEtranslates to webhook.py's--spawn-config profile=NAME, exactly the way--claimalready translates to--include. agent-box's word for the thing stays "profile"; the bus never learns the concept.webhook-spawn.sh— the watch's profile beats both box-wide settings, and is then validated exactly as before: an unusable name is reported and ignored, and the session starts on the box default. A delivery is never dropped over a renamed profile.--preamblehas no delivery and so no variable, so that mode reads the watch out offilter.dispatch.jsoninstead. This matters: the settings page's watch panel prints this preamble, and a panel naming the box-wide worker for a watch that overrides it would be a lie the operator only finds out about from a session that already started (#292). The daemon passes the state dir in and stamps that file into the preamble cache key, so a re-subscribe re-renders instead of serving the old answer for the life of the daemon.webhook-policy-apply.shleavesspawnConfigalone, so--profilesurvives a receiver restart on a governed watch. That was already true of the code; it is now said in the comment, with the reason: a profile is runtime data, which is whyAGENT_BOX_HOOK_PROFILEhas no NixOS option beside it either and whywatchPolicygets no profile field.Pin bumped to local-channels 0.25.0, with the
revoption's description rewritten to say what this pin brings.Docs — the shipped guide (
default-agents.md), the README's profile section, and the CLI's own--help.Checks run

The pin currently points at local-channels#51's branch commit
a59692e, so CI here can run against the code it needs. defangdevs squash-merges, so once #51 lands I will re-pin to the resultingmaincommit (newrev+sha256,nix run .#assemble,nix run .#update-golden) and push. Do not merge this before that re-pin.Also unblocks
#333 wanted the same per-watch field for a different reason (model/profile hints in GH mentions). It is no longer blocked upstream.
