We need to produce a JSON array of tool calls that will achieve the goal: service 'billing-0' must reach at least the 'healthy' state. Entity IDs: services svc_0 (billing-0), svc_1 (webhooks-1). Artifacts: art_0 (release-image), art_1 (db-migration). Flags: flag_0 (maintenance_window_open), flag_1 (secrets_synced).

Current state:
- billing-0 is currently down (not yet provisioned). So service svc_0 is down.
- webhooks-1 is currently down (not yet provisioned). So svc_1 is down.
- release-image artifact does not exist yet (i.e., artifact art_0 is absent).
- db-migration artifact does not exist yet (artifact art_1 absent).
- maintenance_window_open flag is off (i.e., flag_0 is false).
- secrets_synced flag is off (flag_1 is false).

Goal: service 'billing-0' must reach at least the 'healthy' state. That means we need to get svc_0 to healthy. To get healthy, we need to deploy, then health-check. Health-check precondition: service must be deployed, flag_0 must be set, and art_0 artifact must be published. Also health-check moves from deployed to healthy.

Thus we need to:
1. Provision svc_0 (down -> provisioned). Use advance_0 tool with service: svc_0.
2. Configure svc_0 (provisioned -> configured). Use advance_1 tool with service: svc_0.
3. Deploy svc_0 (configured -> deployed). Use advance_2 tool with service: svc_0.
4. Build artifact art_0 (absent -> built). Use build_art_0 with artifact: art_0.
5. Publish artifact art_0 (built -> published). Use publish_art_0 with artifact: art_0.
6. Set flag_0 to true (must be false currently). Use set_flag_0 with flag: flag_0.
7. Health-check svc_0 (deployed -> healthy). Use advance_3 with service: svc_0. Preconditions: service deployed, flag_0 true, artifact_0 published. We'll have satisfied those.

Potentially also need to ensure other flags? Not required for health-check; only flag_0 required. So we can set flag_0.

We also may need to handle webhooks-1? Not required for goal, but maybe we need to ensure we don't break anything? The goal only cares about billing-0 healthy. No constraints about other services. So we can ignore webhooks-1.

We must not exceed 14 tool calls. We'll use 7 calls as above. Let's list them in order:

1. advance_0 with service: svc_0 (provision)
2. advance_1 with service: svc_0 (configure)
3. advance_2 with service: svc_0 (deploy)
4. build_art_0 with artifact: art_0 (build artifact)
5. publish_art_0 with artifact: art_0 (publish artifact)
6. set_flag_0 with flag: flag_0 (set flag)
7. advance_3 with service: svc_0 (health-check)

Check preconditions at each step:

- Initially svc_0 is down. advance_0 precondition: service must be down. Yes.
- After provision, svc_0 becomes provisioned. Next advance_1 precondition: service must be provisioned. Yes.
- After configure, svc_0 becomes configured. Next advance_2 precondition: service must be configured. Yes.
- At this point, artifact art_0 is absent. build_art_0 precondition: artifact must be absent. Yes.
- After build, artifact becomes built. publish_art_0 precondition: artifact must be built. Yes.
- flag_0 is currently false. set_flag_0 precondition: must be false. Yes.
- After setting flag, flag_0 true. health-check precondition: service must be deployed (yes), flag_0 must be set (true), art_0 must be published (yes). So health-check can be executed.

Thus sequence works.

We must output JSON array of objects each with "tool": "<tool id>", "args": {...}. No extra text.

Make sure to use exact tool IDs: advance_0, advance_1, advance_2, build_art_0, publish_art_0, set_flag_0, advance_3.

Parameter names: for advance_0, param is service. For advance_1, param is service. For advance_2, param is service. For build_art_0, param is artifact. For publish_art_0, param is artifact. For set_flag_0, param is flag. For advance_3, param is service.

Thus JSON array:

[
  {"tool":"advance_0","args":{"service":"svc_0"}},
  {"tool":"advance_1","args":{"service":"svc_0"}},
  {"tool":"advance_2","args":{"service":"svc_0"}},
  {"tool":"build_art_0","args":{"artifact":"art_0"}},
  {"tool":"publish_art_0","args":{"artifact":"art_0"}},
  {"tool":"set_flag_0","args":{"flag":"flag_0"}},
  {"tool":"advance_3","args":{"service":"svc_0"}}
]

Check that we didn't exceed 14 calls; we have 7.

Make sure no extra whitespace? It's okay.

Return only JSON array.
