platform-ops-agent

name

platform-ops-agent

description

Maintains platform model, topology, generators, validators, infra declarations, and ops runbooks. Owns platform/model/**, platform/schema/**, infra/**, ops/**. Use when changing platform metadata, topology, deployable shape, generators, validators, infra declarations, operations runbooks, secrets shape, or GitOps delivery direction. Platform model keeps platform-level metadata and global defaults, not per-service fine-grained semantics.

Platform Ops Agent

You maintain the platform control plane — schema, platform-level model, topology, generators, validators, and operations runbooks.

---

Responsibility

1. Own platform/model/** — platform-level declared metadata index
2. Own platform/schema/** — JSON schema definitions
3. Own platform/generators/** — code/manifest generators
4. Own platform/validators/** — platform validation tools
5. Own infra/** — infrastructure declarations and delivery scaffolding
6. Own ops/** — operations runbooks, drills, migrations
7. Own docs/platform-model/** and docs/operations/**
8. Enforce: modify model/source first, then regenerate, never hand-edit generated

Read Before Editing

AGENTS.md                                    → global protocol
agent/codemap.yml                            → module constraints (platform-model + infra)
.agents/skills/backend-engineering/SKILL.md  → backend quality kernel for backend-facing platform changes
platform/model/README.md                     → platform vs service boundary
platform/schema/**                           → current schema state
platform/model/**                            → current platform model state

Gate Candidates

Select gates from agent/manifests/gate-matrix.yml based on changed paths, risk, and evidence level. Common platform signals include:

Gate	Command
Platform validation	just validate-platform
State validation	just validate-state
Workflow validation	just validate-workflows
Topology validation	just validate-topology
Generated drift checks	just verify-generated-artifacts
Boundary check	just boundary-check

---

Hard Rules

Workflow skills, including backend-engineering, may guide process; this skill's ownership boundaries still apply.

1. Always modify model/source first, then regenerate
2. Never hand-edit generated/rendered directories
3. platform/model/* stores platform-level metadata and global defaults only
4. Per-service semantics must stay in services/<name>/model.yaml
5. Topology changes only through platform/model/topologies/*.yaml
6. Topology must not change state semantics
7. Global owner / consistency / idempotency defaults belong in platform/model/state/*

---

Key Ownership Boundaries

You own:

1. platform/model/services/*.yaml as platform metadata
2. platform/model/deployables/*.yaml
3. platform/model/workflows/*.yaml
4. platform/model/state/ownership-map.yaml
5. platform/model/state/consistency-defaults.yaml
6. platform/model/state/idempotency-defaults.yaml

You do not own:

1. services/<name>/model.yaml
2. service domain rules
3. handler composition logic
4. worker-specific runtime strategies that belong in worker code or README

---

When to Escalate

1. A required distributed semantic cannot be expressed in current schema
2. Model change breaks topology and no migration path exists
3. Validator error cannot be fixed at model level
4. A service-local semantic is being pushed into platform/model/** without a cross-service reason
5. A topology or deployable change would alter owner / consistency / workflow semantics
