Session Summary

Built a new /bitdefender Claude Code skill that drives the Arizona Computer Guru GravityZone Cloud partner tenant through the JSON-RPC Public API. The work started from the observation that the web console cannot be accessed programmatically, but a partner-level API key already existed in the SOPS vault (msp-tools/gravityzone.sops.yaml) and a read-only client already lived in the server code at api/services/gravityzone_service.py. The new skill is a standalone CLI that reuses that proven JSON-RPC + HTTP Basic auth pattern and extends it with management operations, an identity-tier JSON cache, and --confirm gating on destructive actions.

The build proceeded in phases. First, the core skill (client gz_client.py, CLI gz.py, SKILL.md, references/api-reference.md) covering read commands (status, companies, endpoints, sweep, policies, packages, quarantine, inventory) and management (create-package, install-links, scan, move, make-group, gated deletes). The API method specs were verified via web research plus live read-only probes against the tenant rather than guessing signatures. Next, security hardening from a code review: API key loaded from the vault at runtime only (never on disk/logs/argv/cache), error-body truncation, and raw destructive-method gating. Then EDR/incident-response commands from the incidents module (blocklist, isolate/unisolate, blocklist-add/remove).

A live all-clients security sweep was run, which exposed a real bug: the all-clients path passed the companies container ID to getEndpointsList, which the API rejects. Fixed by iterating each company individually (mirroring the original server service). The corrected sweep covered 303 endpoints across 40 active companies: 1 infected (BOOKKEEPER at Reliant Well Drilling), 201 with outdated signatures, 6 with outdated agents, 183 stale (>14 days). Most of the "stale/outdated" volume traced to Glaz-Tech Industries (145 endpoints, ~78% stale) which appears to be dead inventory never removed from GravityZone.

A systematic bug-hunting pass followed, backed by a new 29-check read-only self-test harness (selftest.py). It found and fixed: the detection_active field was misleadingly named and inverted (renamed threat_detected, now correctly meaning "active threat, tracks with infected"); the status table rendered nested dicts as unreadable one-line blobs (added a sectioned renderer); and the quarantine command 404'd due to two bugs — wrong module path (needs service-scoped quarantine/computers) and wrong parameter (companyId, not parentId). All 29 self-tests pass. Work was committed and synced.

Key Decisions

  • Built the skill standalone rather than extending api/services/gravityzone_service.py, reusing its JSON-RPC/auth pattern but keeping the skill self-contained and CLI-driven.
  • Cache only the identity/structure tier (company/endpoint/policy id<->name maps, package list) with a 24h TTL; never cache volatile status (infected/last-seen/signature freshness) — those always pull live. A stale "all clean" is worse than a slow truth.
  • Gate all destructive actions (delete-*, isolate, blocklist-add/remove) behind --confirm; raw also refuses destructive method names without it. UNVERIFIED API methods are reachable only via raw, never exposed as convenience subcommands.
  • Verified API method signatures via live read-only probes before wiring them, rather than trusting docs alone — this is how the quarantine companyId/path issue and the incidents license-gating were discovered.
  • Stored CLAUDETOOLS_ROOT in .claude/settings.local.json (gitignored, per-machine) rather than the shared settings.json, so it doesn't break other fleet machines.
  • Scoped v1 to "full management" but deferred the GuruRMM push-deploy and the GravityZone Push webhook to phase 2.

Problems Encountered

  • All-clients sweep crashed (Invalid value for 'parentId'): the no---company path passed the companies container to getEndpointsList. Fixed by adding security_sweep_all_clients() that iterates each company.
  • detection_active field was inverted/mislabeled, producing a false "302/303 detection off" reading. Root cause: malwareStatus.detection means "threat active now" (True=bad), not "engine on." Renamed to threat_detected with corrected semantics.
  • status table mode dumped nested apiKey/license dicts as giant single lines. Added _print_status sectioned renderer; --json output unchanged.
  • quarantine returned HTTP 404. Two bugs: bare quarantine module path 404s (needs quarantine/computers), and the param is companyId not parentId. Both fixed; ACG returns 2 real items.
  • Process error: marked the quarantine task "completed" before verifying; the self-test caught it still failing. Reopened, probed the real signature, fixed, re-verified. Lesson: verify before closing.
  • incidents.getIncidentsList returns "Method not found" on this tenant — EDR/incidents license feature is off (consistent with managePatchManagement/managePHASR being off). Blocklist (same module) works; network isolation likely also needs EDR licensing enabled. Not a code bug.
  • Empty CLAUDETOOLS_ROOT in the Bash tool's non-interactive shell caused early vault.sh path failures. Resolved by adding the env var to settings.local.json and inline-setting it during the session.

Configuration Changes

Created:

  • .claude/skills/bitdefender/SKILL.md
  • .claude/skills/bitdefender/scripts/gz_client.py
  • .claude/skills/bitdefender/scripts/gz.py
  • .claude/skills/bitdefender/scripts/selftest.py
  • .claude/skills/bitdefender/references/api-reference.md

Modified:

  • .gitignore — added .claude/skills/bitdefender/.cache/ and .claude/scheduled_tasks.lock
  • .claude/settings.local.json — added env.CLAUDETOOLS_ROOT = "C:/claudetools" (gitignored, per-machine)

Runtime (gitignored, not committed):

  • .claude/skills/bitdefender/.cache/inventory.json — identity cache (55 companies, 532 endpoints, 9 policies, 100 packages)

Credentials & Secrets

  • GravityZone Public API key: vault entry msp-tools/gravityzone.sops.yaml, field credentials.api_key. Auth = HTTP Basic, key as username + empty password. Loaded at runtime only; never written to disk/logs/cache. Test override: GRAVITYZONE_API_KEY env var.
  • No new secrets created this session.

Infrastructure & Servers

  • GravityZone Cloud Public API base: https://cloud.gravityzone.bitdefender.com/api/v1.0/jsonrpc
  • Module path form: <base>/<module> (e.g. /network, /packages, /incidents). Quarantine requires service-scoped /quarantine/computers.
  • ACG tenant IDs: ACG_ROOT_COMPANY_ID = 5c4280716c0318f3478b456a, ACG_COMPANIES_CONTAINER_ID = 5c4280716c0318f3478b456e. In getNetworkInventoryItems, type == 1 = company node.
  • Tenant scale: 55 client companies, ~532 managed endpoints, 128 used license slots, key expires 2030-02-17. Enabled API modules: companies, licensing, packages, network, integrations, policies, maintenancewindows, reports, accounts, incidents, push, quarantine, phasr, patchmanagement. License features OFF: managePatchManagement, managePHASR, EDR/incidents listing.

Commands & Outputs

  • py .claude/skills/bitdefender/scripts/gz.py status — license/slots/enabled modules.
  • py .../gz.py sweep [--company <id>] — live posture; no --company sweeps all clients.
  • py .../gz.py quarantine --company <id> — fixed; ACG returned 2 items (Gen:Heur.Ransom.HiddenTears.1 on ACG-DC16 — assessed by Howard as a Datto program false positive, to review later).
  • py .../gz.py inventory --refresh — rebuild identity cache.
  • py .../scripts/selftest.py -> 29/29 passed, 0 failed.
  • Sweep result: 303 endpoints / 40 active companies; infected=1 (BOOKKEEPER @ Reliant Well Drilling), signature_outdated=201, product_outdated=6, stale>14d=183. Glaz-Tech Industries dominates stale/outdated (145 eps, ~78% stale — likely dead inventory).
  • Live API errors observed (correct handling, exit 1): Invalid value for 'parentId' parameter (bad company), Invalid value for 'endpointId' parameter (bad endpoint), Method not found (incidents.getIncidentsList — license gated).

Pending / Incomplete Tasks

  • ACG-DC16 quarantine entry (Gen:Heur.Ransom.HiddenTears.1) — believed to be a Datto program false positive; Howard to review further. Not remediated.
  • Glaz-Tech Industries dead-inventory cleanup — separate genuinely-offline-but-live machines from decommissioned records (inflating counts + burning license seats). Not started.
  • EDR network isolation (isolate/unisolate) is wired but untested live; likely needs EDR/XDR licensing enabled on the tenant (a Bitdefender toggle). Mike decision.
  • UNVERIFIED methods (assignPolicy, uninstall/reconfigure, quarantine restore/remove) remain raw-only until signatures confirmed live.
  • Phase 2 (deferred): GuruRMM push-deploy of installer links; GravityZone Push webhook to keep cache event-fresh instead of polling.
