Summary

  • Give each standing watch an authMode in its saved spawn config. New watches default to api-key; existing watches keep their legacy behavior, and --auth saved-login is an explicit opt-in.
  • Check the selected profile before saving or dispatching. Claude uses the profile's ANTHROPIC_API_KEY. Codex uses OPENAI_API_KEY in a dedicated CODEX_HOME, initialized with codex login --with-api-key over stdin. Missing credentials defer dispatch instead of starting on another login.
  • Add an authentication selector and status to the settings watch editor, plus agent-box-webhook auth-status TOPIC [--name NAME] for scripts. Update the shipped guide and README.
  • Keep provider keys out of watch rules, command arguments, and UI output. Refuse Codex auth files that link to another login.

Verification

  • nix build -L --keep-going .#ci-native
  • nix eval --raw .#checks.x86_64-linux.webhook.drvPath
  • Focused watch and CLI regression tests cover creation, renewal, settings, Codex login, and dispatch after a key is removed.

The box running these checks is ARM, so the x86 webhook VM test is left to CI. A configured key is checked locally; provider acceptance and Claude's possible one-time key approval happen in the provider CLI.

Closes #812

📝 Walkthrough

Walkthrough

Standing webhook watches now support API-key, saved-login, and legacy authentication modes. New watches default to API-key authentication, with profile readiness checks at creation and dispatch. The CLI and settings page report authentication status, and existing watches without a mode retain their previous behavior.

Changes

Standing Watch Authentication

Layer / File(s) Summary
API-key readiness and dispatch
modules/agent-box.nix, modules/src/webhook-spawn.sh, tests/golden/web/payloads/agent-box-webhook-spawn/bin/agent-box-webhook-spawn, tests/test-watch-profiles.py
The spawn helper checks Claude and Codex profile requirements and can prepare Codex API-key login. It reports readiness and defers a nonempty batch with status 75 when preparation fails. Tests cover missing keys, conflicting credentials, and Codex auth-file handling.
CLI watch configuration and status
modules/src/webhook-cli.sh, modules/src/contract/wrappers.json, tests/golden/web/payloads/agent-box-webhook/bin/agent-box-webhook, tests/native/expected/usr/local/bin/agent-box-webhook, tests/test-watch-profiles.py, tests/test-webhook-claim.sh, tests/webhook.nix
The CLI adds --auth and auth-status, merges existing watch configuration, and prepares API-key watches before saving. The webhook wrapper exports the pinned spawn command. Related tests select saved-login explicitly and cover configuration preservation and status reporting.
Settings save and readiness display
modules/src/settings-daemon.py, modules/agent-box.nix, tests/golden/web/payloads/agent-box-settings/bin/agent-box-settings, tests/test-watch-profiles.py
Settings saves accept the supported modes and reject API-key rules that are not ready. The editor offers authentication choices, and watch rows display mode and readiness. Tests cover settings saves and rendered status.
Authentication guidance
README.md, modules/agent-box.nix, modules/src/default-agents-webhook.md, modules/src/webhook-cli.sh, tests/golden/web/etc/agent-box-guides/*, tests/native/expected/etc/agent-box-guides/*
The documentation describes provider-key requirements, saved-login fallback, API-key dispatch deferral, auth-status, and legacy behavior for existing watches.

Merge Risk: 🟡 Moderate · up to 821e2

Creating a watch from the settings page fails unless the user changes the authentication selection. Codex credential preparation can stall later saves and dispatches for the same Codex home. A status check can report the wrong mode when the topic's letter case differs. Fix these before merging.

Security Architecture Review

Security architecture risk: 🔵 Low · up to 821e2

The new checks reduce unintended login fallback. Remaining risks concern authentication state shared between profiles, inconsistent readiness reporting, and inherited authentication settings. The demonstrated exposure is bounded to an existing user’s watches and sessions; no broader access expansion was established.

Retained concerns

  • Low · security · inferred: New Codex preparation mutates a profile-selected auth file without enforcing exclusive ownership of its resolved home. Preparation can remain after a rejected watch save, and its lock does not bind the saved identity to later asynchronous provider startup. Profiles sharing a home can therefore replace credential state before another queued session starts. Actual provider credential-selection consequences remain unverified; this is a same-user identity-consistency risk, not demonstrated cross-user privilege escalation.
  • Low · security · observed: The new auth-status command validates watch identity case-insensitively but delegates lookup using the original topic spelling. The helper requires exact equality and treats an unmatched configuration as legacy and ready. Scripts can consequently receive a successful readiness result for the wrong authentication mode. This affects the reporting contract; dispatch with the matched configuration still performs its own readiness check.
Security review details

Security Blast Radius

  • inferred — The demonstrated independently affected scope is watches and sessions sharing a Linux user, inherited agent authentication settings, or a configured Codex home. Consequences can extend to the external provider identity and account authority represented by those credentials. The inspected paths do not demonstrate cross-user credential access or increased operating-system privileges.

Security Findings and Attack Paths

  • observed — The retained reportable finding is low severity with internal reachability. Claude readiness checks read conflicting variables from profile and user-store files, whereas provider startup also retains inherited authentication variables. The underlying inheritance behavior predates this PR; broader exposure was not established. Profile precedence is counterevidence against an inherited value overriding the same explicitly supplied key, but does not clear differently named authentication selectors. Provider approval and credential-selection behavior remain incompletely verified.

Trust Boundaries and Controls

  • observed — Settings watch saves validate topic, name, profile, mode, and existing watch identity before persistence. The helper executable and operation are fixed, and configuration is passed as JSON through the environment. The settings handler retains its same-origin POST guard and authenticated-UI contract; upstream proxy deployment enforcement was not independently verified.
  • observed — Codex homes must resolve beneath HOME and differ from the default home. Existing auth-file symlinks and multiple hard links are rejected. Preparation verifies the saved API key, applies directory mode 700 and auth-file mode 600, and avoids placing the key in command arguments or helper output. These controls do not enforce unique home ownership between profiles.

Resilience and Maintainability Implications

  • observed — API-key preparation failure blocks persistence or returns retryable dispatch exit 75. This is meaningful counterevidence against ordinary missing-key fallback. Local readiness does not prove provider acceptance, transactional watch-and-credential updates, or identity stability after asynchronous admission.

Hardening Proposals

  • proposed — Define exclusive ownership of resolved Codex homes and bind preparation to the identity actually consumed at provider startup. Complete save validation before credential mutation, and specify durable-preparation and recovery behavior rather than assuming watch persistence rolls authentication state back.
  • proposed — Use one canonical watch identity for status lookup and fail explicitly when resolution misses. Align authentication checks with the effective provider environment, including inherited authentication selectors, without treating profiles as same-user secret isolation.

modules/agent-box.nix:10071-10079
🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Use the same topic comparison as the CLI when the spawn helper reads a watch's configuration.

agent-box-webhook auth-status (lines 7701-7703) finds the watch with a case-insensitive topic match (ascii_downcase). Line 7871 in subscribe does the same. The spawn helper reads spawnConfig with a case-sensitive match: (.topic // "") == $t.

Example: the CLI receives github:Owner/Repo, and the dispatch file stores github:owner/repo.

  • The CLI accepts the watch.
  • The spawn helper finds no entry.
  • watch_config falls back to {}.
  • auth-status reports mode: legacy, ready: true for an API-key watch.

--preamble and --resolved-profile read spawnConfig the same way, so they can show the wrong profile for that watch.

Make the change in modules/src/webhook-spawn.sh, then regenerate this file with nix run .#assemble.

Proposed fix
-    '[(.topics // [])[] | select(type == "object" and (.topic // "") == $t and (.name // "") == $n)][0]
+    '[(.topics // [])[] | select(type == "object" and ((.topic // "") | ascii_downcase) == ($t | ascii_downcase) and (.name // "") == $n)][0]

Cover the default create form in the settings test.

The test posts create without an auth field. The real create form always posts the auth select value. Because of the editor bug in render_watch_editor, that value defaults to legacy. Render the create editor and assert that api-key is the selected option, so the browser path is tested.

Assert authMode in the signed-dispatch test.

The pinned receiver forwards the opaque spawnConfig map, so it does not currently drop authMode. However, the signed-dispatch test checks only profile. If a future pin drops authMode, the test can still pass while webhook-spawn.sh defaults to legacy and skips the API-key readiness check. Assert the recorded mode too.

Suggested test assertion
-                launches = [json.loads(s)['profile'] for s in output.read_text().splitlines()]
+                launches = [json.loads(s) for s in output.read_text().splitlines()]

to use a bounded wait and fail closed if acquiring the lock times out. Close
file descriptor 9 on every return after acquisition, including the successful
Codex branch, so the lock is released before the function returns.
