Only `read_only` and `safe` are accepted; the program exits on anything else. Provider credentials, if a provider needed any, would be in the server's process environment and never in the model's context. -- The server writes its audit sink, `stackql_mcp_server_.log` (JSONL, one line per tool call), into its working directory, so the agent starts it in `STACKQL_AUDIT_DIR` (default `runs/`) and prints the path at the end of the run. -- The system prompt is `prompts/system.md` plus the server's own instructions from the MCP initialize handshake, so the platform's current guidance travels with the briefing. The user prompt is `prompts/intent.md`. Both have `{{ placeholders }}` filled from `.env`; a missing value fails the run naming the variable. -- Tools are whatever the server exposes (`mcpClient.tools()`), passed to `generateText` with `stopWhen: isStepCount(AGENT_MAX_STEPS)`. The write tools stay visible by default so the server's refusal is what you see on screen; set `AGENT_HIDE_WRITE_TOOLS=true` for the production posture, where the model is never offered them. -- In `safe` mode the server raises an MCP elicitation before a write. The agent answers it from the terminal (approve or decline). A run with no TTY attached, such as the CronJob, declines automatically: a scheduled run has nobody to ask. -- Model options: adaptive thinking (always on for the Claude 5 family), `effort` from `ANTHROPIC_EFFORT` (`medium` default; it is the latency and cost control), and `fallbacks: 'default'` so a safety-classifier refusal is retried server-side on a fallback model. -- Every run ends with a block: steps, tool calls by name, writes attempted, tokens, a list-price estimate from the pricing table in the source, and the audit log path. - -## the agent as a workload - -```bash -docker build -t platform-agent:dev agent/ -kind load docker-image platform-agent:dev --name platform-demo -kubectl create secret generic platform-agent -n shop --from-literal=ANTHROPIC_API_KEY="$ANTHROPIC_API_KEY" -kubectl apply -f k8s/agent-cronjob.yaml # remove the Secret stanza from the file first, or let it be overwritten -kubectl -n shop create job --from=cronjob/platform-agent platform-agent-now -kubectl -n shop logs job/platform-agent-now -c agent -f +These commands make paid API calls.

Start the proxy with `kubectl --context=kind-platform-demo`; the scripts do not switch the user's active context. The stack manifest and provider version should be reviewed before use. + +## Approval and audit boundary + +The only mutation-shaped capability is a proposal for the single approved image in the `shop/checkout` fixture. The model cannot invoke an executor. `read_only` cannot mutate even with a valid test approval; `safe` requires an exact-plan confirmation and an approver identity. The local CLI identity prompt is self-attested and is teaching-only, not a production authenticated approval interface. -## status +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. -What has been exercised and what has not, as of the scaffold (16 October 2026, Windows, no cluster and no model key on the machine): +## Retained StackQL/Kubernetes materials -Verified: +`stack/`, `scripts/`, and `k8s/` preserve the original local-kind and StackQL example for study. 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. Never apply it as evidence of a validated live agent path. -- `npm run typecheck` passes; `--list-tools` starts the server through the npm launcher (stackql 0.12.778) and lists 15 tools in `read_only` mode, with the audit sink opened in `runs/`. -- `--probe-write` in `read_only`: the server refuses before any API call (`decision: refuse_immediate` in the audit sink). -- `--probe-write` in `safe`: the server raises an elicitation, the agent prints the approval box, a non-TTY run declines, the server records `needs_approval_declined`. Two client settings were needed for this and are in `agent.ts` with comments: advertise the `elicitation` capability, and turn off the SDK's `server/discover` probe so the session negotiates the 2025-11-25 revision (on 2026-07-28 the gated write comes back as an `input_required` result the SDK does not round-trip yet). -- `stackql-deploy build stack demo --dry-run` renders every query for all five resources. +Official references: [OpenAI function calling](https://developers.openai.com/api/docs/guides/function-calling), [OpenAI models](https://developers.openai.com/api/docs/models), [OpenAI SDK libraries](https://developers.openai.com/api/docs/libraries), [AI SDK OpenAI provider](https://ai-sdk.dev/providers/ai-sdk-providers/openai), and [AI SDK tool calling](https://ai-sdk.dev/docs/ai-sdk-core/tools-and-tool-calling). -Not yet exercised: +## Migration from the original demo -- The stack has not been built against a cluster, and the agent has not been run with a model. The resource files follow the k8s stacks in the KSUG and OpenAI sibling demos, which did run against real clusters. -- The CronJob manifest and the Dockerfile are written, not applied or built. Check the sidecar image tag against the cluster version before the first apply. -- `describe_method` with method `list` fails to parse on this server build (`list` is a reserved word); `get` works and returns the same output columns. The agent may hit this when it discovers a `list` method; the prompt tells it to use `describe_method`, so watch for it on the first real run and raise it upstream. +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.

Wednesday 28 October, 4:50 PM to 5:15 PM (25 minutes, last slot of the day). Speaker: Jeffrey Aven, StackQL. +**Cloud Native AI Summit Melbourne** · Wednesday 28 October 2026 · MCEC · 16:50–17:20 +**Content:** 20 minutes · **Q&A:** 5 minutes · Speaker: Jeffrey Aven -The spine of the talk: platform engineering is a product discipline built for one persona, the human developer. The persona has changed. This deck walks through what inverts when the customer of the platform is an agent, then shows a platform built for that customer: a Kubernetes estate as a stackql-deploy stack, an always-on agent on the Vercel AI SDK and Claude using the StackQL MCP server, with agency set by the platform (server mode, identity, tool surface) rather than by the prompt. +The thesis: agents should query authoritative platform state before proposing a change. Deterministic policy, separately scoped identities, human approval, and post-change verification—not a persuasive prompt—govern execution. -Earlier talks (AI Engineer Melbourne June 2026, AAIF Melbourne August 2026, KSUG Melbourne September 2026) covered "infrastructure as data", the four strains in IaC and the six patterns. This deck compresses that material to one slide and does not repeat the Cloudflare and Confluent demo. +This is a 16:9 slide source with speaker notes and demo cues. The live cluster/model path is not validated; use it only after release gates pass. Otherwise play a clearly labelled recording or fixture replay. Do not represent fixture output as a live run. -Budget: 14 content slides plus the demo. Finish at 24:00. No Q&A buffer is realistic in a 25 minute end-of-day slot. +## Slide 1 — Title · 0:30 (cumulative 0:30) -## Slide 1 - Title +**AI native platform engineering** +Building the platform when agents are the primary consumer -**Title:** AI native platform engineering: building the platform when agents are the primary consumer +Cloud Native AI Summit Melbourne · Jeffrey Aven · 28 October 2026 -**Content:** +**Visual:** A platform contract and a tightly scoped tool call; no robot stock art. -- Cloud Native Summit APAC 2026, Melbourne -- Jeffrey Aven, StackQL -- stackql.io, github.com/stackql +**Speaker note:** “The platform is still a product. The consumer now includes an agent that needs structured, discoverable contracts and an execution boundary it cannot prompt its way around.” -**Image idea:** Full-bleed dark slide. A single Kubernetes Pod spec rendered as a code block on the left, with one highlighted line `serviceAccountName: platform-agent`. No stock imagery, no robots. +## Slide 2 — Start with a familiar incident · 1:30 (2:00) -**Time:** 0:00 to 0:30 +- 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?” -## Slide 2 - Who is the platform for? +**Speaker note:** Describe the synthetic image-pull incident; identify it as a disposable example, not customer telemetry. -**Title:** Platform engineering was built for one persona +## Slide 3 — The platform has a new consumer · 1:00 (3:00) -**Content:** +- 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. -- Platform as a product, developers as the customers (CNCF platforms white paper, Team Topologies) -- The whole playbook is about reducing developer cognitive load: portals, golden paths, self-service, scorecards, docs -- Every one of those is a product decision made for a human -- Ask the product question: who is actually using the platform in 2026? +**Visual:** Human and agent personas side by side, each with a distinct interface. -**Image idea:** A persona card in the style of a UX research template. Name, role, goals, frustrations. "Priya, backend engineer. Wants to ship. Hates tickets and waiting on the platform team." Keep it to one card, centred. +## Slide 4 — One contract, progressive discovery · 2:00 (5:00) -**Time:** 0:30 to 2:00 +1. Discover a capability. +2. Read its precise schema and constraints. +3. Query current state and the authoritative desired-state artifact. +4. Propose a typed plan against fresh evidence. -## Slide 3 - The new persona +**Concrete example:** StackQL offers a queryable platform surface; the safety pattern is tool-agnostic. Do not expose an unrestricted SQL or arbitrary patch tool as the repair operation. -**Title:** Meet the new customer +**Speaker note:** A human may still use a portal or PR. The platform adds an agent-readable contract rather than declaring those interfaces obsolete. -**Content:** +## Slide 5 — Query before mutation · 2:00 (7:00) -The agent persona, on the same card template: +**Evidence first** -- Arrives with no memory of the last run -- Reads fast, follows structure, cannot browse a portal -- Retries and resumes by default -- Runs in parallel with copies of itself -- Never sleeps, never waits for office hours -- Can be prompt-injected by anything it reads -- Bills per token, not per seat +- Current target and namespace +- Resource version / evidence identifier +- Observed image, readiness, and event +- Approved desired image from a trusted artifact -Every requirement in the rest of the deck is derived from this card. +**Then:** validate scope → calculate exact plan → revalidate freshness → request approval. -**Image idea:** A second persona card beside the first, identical template. The agent card has no photo, just a cursor. The two cards side by side is the visual for the whole talk; reuse it as a section divider. +**Visual:** Evidence card and desired-state card flowing into one canonical plan. -**Time:** 2:00 to 3:30 +## Slide 6 — Controls belong in the process · 3:00 (10:00) -## Slide 4 - The inversion (part 1) +| Boundary | Enforced by | +| --- | --- | +| What can be called | Strict schema and application allowlist | +| What can be read | Read-only identity and target scope | +| What can be changed | One narrow operation, approved desired value only | +| Who may approve | Authenticated operator interface, bound to exact plan and expiry | +| Whether it worked | Fresh post-change read and explicit verification | -**Title:** What inverts when the customer changes +- Denial is terminal for that action; no alternate tool or prompt-based retry. +- An uncertain result triggers verification, never a blind duplicate mutation. +- Application policy is still not a lock: use atomic resource-version preconditions where available. -**Content:** +**Speaker note:** In this local teaching fixture, approval identity is self-attested; it is explicitly not the production approval service. The production/live integration remains a release gate. -| Built for developers | When agents are the consumer | -|---|---| -| Portal and UI (Backstage) | Self-describing interface (MCP: list, describe) | -| Golden path is a template you copy | Golden path is a vetted query the agent searches for by intent, plus policy it cannot exit | -| Reduce cognitive load by hiding complexity | Manage context load with progressive disclosure | -| Docs the human reads | The interface is the documentation | -| Self-service through a form, ticket or PR | Self-service through a tool call, with the gate in the tool | +## Slide 7 — Demo setup · 1:00 (11:00) -**Image idea:** Two-column table, left column in grey, right column in the accent colour. Rows animate in one at a time if the deck tool supports it; otherwise show all five. +**Synthetic checkout incident** -**Time:** 3:30 to 5:00 +`ImagePullBackOff` → read-only inventory → approved desired image → exact plan → operator gate → fixture verification -## Slide 5 - The inversion (part 2) +- Live version: isolated, disposable cluster only, after preflight. +- Fallback: local recording or labelled deterministic fixture replay. +- Both versions use the same scenario and safety outcomes. -**Title:** What inverts when the customer changes (continued) +## Slide 8 — Demo · 4:00 (15:00) -**Content:** +| Time | Beat | +| --- | --- | +| 0:00–0:40 | State that this is fixture replay or live isolated target; show incident and desired state. | +| 0:40–1:20 | Discover inventory; read evidence ID, resource version, event. | +| 1:20–2:00 | Attempt an out-of-scope/arbitrary image proposal; show deterministic denial and stop. | +| 2:00–2:50 | Separate operator instruction: propose the approved image using fresh evidence. | +| 2:50–3:30 | Show exact plan, approval binding, and single narrow operation. | +| 3:30–4:00 | Fresh verification and audit summary; disclose whether fixture or live. | -| Built for developers | When agents are the consumer | -|---|---| -| PR review is the safety mechanism | Server mode is the safety mechanism | -| Onboarding takes weeks | Onboarding takes seconds: discover, describe, validate, run | -| One identity per human | One identity and one scoped tool server per agent | -| Scorecards run quarterly | Scorecards run continuously; the agent is subject and evaluator | -| Audit log is a compliance artefact | Audit log is the substrate the next run reads from | +**Cue:** A denial does not trigger an automatic reformulation. The operator starts the corrected proposal separately. -**Image idea:** Same table styling as slide 4. Bottom caption: "Same discipline. Different customer." +## Slide 9 — Operate it like a workload · 2:00 (17:00) -**Time:** 5:00 to 6:30 +- Separate identities for read-only and approved mutation paths. +- Explicitly scoped credentials; do not inherit a developer's default context. +- Bounded turns, output, time, and calls; API provider limits are separate spend controls. +- Correlated, structured audit; local logs are not durable evidence unless storage and retention prove it. +- Reset only positively identified lab-owned resources. -## Slide 6 - Context load replaces cognitive load +**Speaker note:** The checked-in CronJob is suspended and read-only; it is not a validated live agent deployment. -**Title:** Context load replaces cognitive load +## Slide 10 — What this does not solve · 1:30 (18:30) -**Content:** +- A permitted, valid change can still be semantically wrong. +- The approved desired state itself may be wrong. +- A preflight read is not a lock; stale observations and API races remain. +- Prompt injection and outages are reduced by boundaries, not eliminated. +- The self-attested local approval and synthetic fixture do not prove production identity, RBAC, or atomicity. -- For humans, the platform reduces cognitive load by hiding complexity behind abstractions -- An agent has a context budget, not a cognitive one. An abstraction that hides something from the human also hides it from the agent -- What the agent needs is progressive disclosure: start wide and cheap, narrow to one contract, then act -- In StackQL terms: list_services -> list_resources -> list_methods -> describe_method -> validate -> run -- The k8s provider: 20 services, hundreds of resources, and the agent loads one method's contract into context, not the whole API +## Slide 11 — Checklist · 1:00 (19:30) -**Image idea:** A funnel diagram. Top: "20 services". Next: "1 resource". Next: "1 method and its IO contract". Bottom: "1 statement". Each band labelled with the tool call that produces it. Monospace labels. +Before an agent may write: -**Time:** 6:30 to 8:00 +1. Can it show fresh evidence and an authoritative desired value? +2. Is the operation narrower than a generic patch? +3. Can the read identity mutate? (It must not.) +4. Is approval authenticated and plan-bound? +5. Is the outcome verified without blind retries? -## Slide 7 - Golden paths as data +## Slide 12 — Close · 0:30 (20:00) -**Title:** Golden paths as data +**Build the contract. Bound the identity. Verify the outcome.** -**Content:** +Repository source: [stackql-labs/agentic-platform-engineering](https://github.com/stackql-labs/agentic-platform-engineering) -- The developer golden path is a template directory you copy and then diverge from -- The agent golden path has two parts: a vetted query it finds by intent (the query library), and a boundary it cannot exit (server mode, RBAC, tool filter) -- The platform team writes the templates and sets the boundaries.

It is a constraint +**Q&A:** separate 5-minute buffer; do not consume it with content.

Nothing the agent reads can change a mode -- This is the platform equivalent of admission control, and it belongs to the platform team - -**Image idea:** Three identical speech bubbles with the same text "scale checkout to 2 replicas" pointing at three server boxes labelled read_only, safe, full_access, with three outcomes beneath: "refused", "approve?", "done". The bubbles are identical on purpose. - -**Time:** 9:15 to 10:30 - -## Slide 9 - The agent is a workload - -**Title:** The agent is a workload - -**Content:** - -- Schedule it: a CronJob, not a chat window -- Give it an identity: a ServiceAccount and a Role. The Role is the blast radius -- Bound its tool surface: server mode and a filtered tool list, in the Pod spec -- Observe it: an audit log of every statement, tokens and cost per run -- Everything on this slide is a thing platform engineers already know how to build and review - -**Image idea:** A Pod spec on the left (CronJob with two containers: the agent and a kubectl proxy sidecar), four callouts to the right pointing at `schedule`, `serviceAccountName`, the mode env var, and the audit volume mount. - -**Time:** 10:30 to 11:30 - -## Slide 10 - Demo setup - -**Title:** Demo: a platform built for the agent persona - -**Content:** - -- The estate: a `shop` namespace with two deployments and a service, declared as a stackql-deploy stack and asserted against the live API (no state file) -- The platform: the StackQL MCP server in `read_only` mode, the k8s provider, an audit log, credentials in the server process and never in the model -- The agent: Vercel AI SDK, Claude, an intent in prose.

The safe isolated live equivalent is a workshop delivery gate, not currently implemented or validated. Track requirements and expected audit outcomes are in [the track guide](tracks/README.md). + +1. Choose one track and one language. +2. Implement one read/assert and one unsafe denial. +3. Create a canonical proposal tied to fresh evidence and the approved value. +4. Test missing, expired, altered, and stale approval/evidence. +5. Verify the outcome; do not return success if verification fails. + +**Checkpoint:** Shared tests and your track-specific assertions pass. Your result distinguishes fixture simulation from live execution. + +## Bounded Codex prompt + +> In this repository, implement only the selected Lab 2 track using the shared fixture and existing safety dispatcher. Do not add network calls, credentials, arbitrary SQL/patch tools, or live resource access. Keep the read identity unable to mutate.

Do not substitute another model family or use a personal paid key. +- **Live environment unavailable:** switch to fixtures/recorded output and label it; organizers must decide whether the promised live workshop can proceed. +- **Approval/verification fails:** preserve the denial; do not retry under a different tool or identity. + +## Reset and evaluation + +The core labs change only in-memory fixture objects and need no teardown.
