It proposes nothing until it has read live state. | +| 02 Idempotent assertions | `scripts/build.sh` is one `stackql-deploy build`: exists -> create, statecheck -> update. The same command builds the estate and converges it after the drift. | +| 03 Bi-temporal view | What is: the live queries. What was: the Warning events and the audit log of earlier runs. What should be: the manifest, which the agent reads as its declared-intent table. Drift becomes diagnosable, not an alarm. | +| 04 Agents as event sources | Every tool call is one record in the server's audit sink, a JSONL file per run in `runs/` (statement, mode, decision, duration, never the rows). `npm run audit` shows the run as an event log. The same sink can be written as OTLP/JSON for an OpenTelemetry collector (`--mcp.log.format=otel`). | +| 05 Universal interfaces | One query shape: the same `SELECT ... WHERE` against the cluster and against GitHub (`github.repos.releases`) to check whether the hotfix tag exists upstream. | +| 06 Policy gates | The server mode is set by the platform in code. `read_only` refuses the write however the model asks; `safe` raises an MCP elicitation and a human approves or declines, bound to the exact statement. `AGENT_MAX_STEPS` bounds the run. | -These commands make paid API calls.

The agent escalates the web drift rather than reverting it; the convergence step is the operator's decision, which is the point: the declaration wins, and if the scale-up was right, the declaration is what should change. -The fixture mutator verifies fresh evidence, exact plan digest, target, approval identity presence, bounded expiry, and a single-use operation, then reads back the result. It emits structured in-memory audit events with a correlation ID; that is not durable audit retention. Fixture state is synthetic and in-memory. It is not evidence of Kubernetes RBAC, atomic resource-version enforcement, or a real live repair. +## fallback -## Retained StackQL/Kubernetes materials +`npm run agent -- --replay` replays the newest transcript from `runs/` (or from `recordings/` when `runs/` is empty) with the pacing of a run, under a banner that says it is a replay.

These files are not wired to the new fixture agent. The stack manifest pins its Kubernetes provider; setup avoids pulling an unpinned provider. Mutation scripts now require explicit disposable-cluster confirmation, and the CronJob example is suspended/read-only.

The agent re-reads after a change; nothing here is an atomic precondition. +- The approval at the terminal is the MCP elicitation flow answered by whoever is at the keyboard. It binds the answer to the exact statement; it is not an authenticated production approval service. +- The agent's blast radius is the identity `kubectl proxy` runs with. On kind that is the admin context; in a real cluster it is a Role on the agent's ServiceAccount, as in `k8s/agent-cronjob.yaml`. +- `safe` and `delete_safe` trust the MCP client to show the prompt to a person; against an untrusted client use `read_only` or a narrowed tool set. -## Migration from the original demo +## status -The previous `agent.ts` used Vercel AI SDK with Anthropic and exposed a broad StackQL MCP tool surface. It could propose generic SQL mutations; it did not implement deterministic application policy or a successful agent-approved repair. The new `agent.ts` is an OpenAI Responses API fixture runner. The old prompts and manifests are retained only as updated/guarded teaching artifacts. No automatic StackQL MCP compatibility path is enabled. +Dry run on 27 October 2026 (Windows 11, Docker Desktop with cgroup v1, kind 0.33 on `kindest/node:v1.33.1`, stackql 0.12.824, `@stackql/mcp-server` 0.12.824, `@ai-sdk/mcp` 2.0.85, `claude-sonnet-5-5`): the full running order ran end to end. The agent run takes about 45 seconds and 5 steps; `recordings/agent_dry-run_2026-10-27.txt` is its transcript. In `read_only` the write was refused; in `safe` the elicitation was raised and recorded (`needs_approval_declined` when nobody answers). The convergence put web back to 2 replicas and checkout back on the declared image. The CronJob manifest and the Dockerfile are written, not applied or built for this talk. diff --git a/10-26 Cloud Native AI Summit APAC/demo/agent/package-lock.json b/10-26 Cloud Native AI Summit APAC/demo/agent/package-lock.json index 7d89496..7bcb967 100644 --- a/10-26 Cloud Native AI Summit APAC/demo/agent/package-lock.json +++ b/10-26 Cloud Native AI Summit APAC/demo/agent/package-lock.json @@ -1,16 +1,20 @@ { "name": "platform-agent", -

The consumer now includes an agent that needs structured, discoverable contracts and an execution boundary it cannot prompt its way around.” - -## Slide 2 — Start with a familiar incident · 1:30 (2:00) - -- A checkout deployment is unhealthy. -- A human starts with current state, events, and the approved desired state. -- An agent can do the same work quickly—but it can also guess, retry, or act on stale evidence. -- The question is not “does the agent sound confident?” It is “what can it actually do?” - -**Speaker note:** Describe the synthetic image-pull incident; identify it as a disposable example, not customer telemetry. - -## Slide 3 — The platform has a new consumer · 1:00 (3:00) - -- Agents need machine-readable contracts and progressive discovery. -- They need bounded context and explicit evidence, not a giant schema dump. -- They can run repeatedly and in parallel; tool output can contain hostile instructions. -- Human developer portals remain useful. Agent interfaces complement them. - -**Visual:** Human and agent personas side by side, each with a distinct interface. - -## Slide 4 — One contract, progressive discovery · 2:00 (5:00) - -1.
