audit-credential-lifetimesAudit how long each credential keeps working after it should stop: one row per credential kind (auth session, API key, operator token, sign-in, socket ticket, and any other the code has) and channel (HTTP request, realtime socket, bus control message, worker), with where it is checked, how often, wh
audit-database-callsAudit how many database calls each endpoint and each worker flow makes, at its least and at its most: round trips, transactions, and roles, counted at the driver while the real API and worker run in one process over a database of their own. Names what grows a flow, every N+1, every read repeated wit
audit-deploy-timeAudit where a deploy's minutes go: the pipeline's jobs and steps from the Actions run, the Terraform apply's resources, the migration's one-off task, each service's rollout from its ECS events, its tasks, and their first log lines, and the settings that pace them (health-check grace, container healt
audit-provider-callsAudit every call to an external provider (WorkOS, the AWS services, any HTTP to a third party), per flow: each route, inbound webhook, worker job, and boot. For each flow, the calls in order, whether they repeat or stand apart, whether they sit on the request path, how often the flow runs, whether t
audit-query-indexesAudit whether the indexes fit the queries, and what breaks first under load: every statement the Postgres storage sends, mapped to the index that serves it and measured with EXPLAIN on a database of its own seeded at a stated scale, under the login and the tenant scope the application uses. Reports
audit-retentionAudit which stores grow without bound and what trims them: every table of every role, with what writes it, when a row is stale, the purge that deletes it, its retention, and whether that purge is batched and indexed; then the stores outside the database (log groups, buckets, queues, the cache). Meas
docs-compactCompact the tree's documents to what holds at the head of the main branch: rewrite each ADR to its present decision with a status of one date, remove the ADRs that constrain nothing, cut the changelog to the latest release, clean the rows of specs/architecture.md, and rewrite the comments that tell
ops-cloud-deployment-createCreate one cloud environment of the system from nothing, in its own AWS account, as that account's administrator: the bootstrap root (state bucket, registry, OIDC trust, the deploy roles, the investigate role, the budget, the zones), the delegation of its public names at Cloudflare, the investigate
ops-cloud-deployment-nukeDestroy one cloud environment of the system as its account's administrator: empty the buckets, destroy the environment root, remove what Terraform does not own (the secrets the application wrote, whose tenants' share follows the database's final snapshot, and the leftovers AWS made), and report what
ops-infra-as-codeWrite or change the system's Terraform in the shape the guideline prescribes: one module graph shared by every environment, a variable for everything that differs, the autoscaling switch, the destroyable switch, the budget, the alarms, and the tags; then plan it under the read-only investigate profi
ops-integration-silentSay why an integration went silent, in one environment, with a read-only credential: count what its inbound webhook route answered, read what the worker made of each delivery and the lines it logged, and read the webhooks queue and its dead letters, then report where the deliveries stop, why, and wh
ops-investigateInvestigate one environment of the system with a read-only credential: the alarms, the error rate, the latency, the outcomes, gauges, queues, and log lines each namespace's signals file names, the pool, the cost against the budget, and the system's size, then report what is wrong and what to do next
ops-root-causeFind the root cause of one tenant's problem in one environment: read that tenant's rows through the operator plane's read routes with a read-only operator token, correlate them with the logs, the trace, and the error event by request id, at most five ids and one pass each, and report the cause and t
ops-simulate-trafficDrive realistic traffic at one environment of the system through its edge with the system's own traffic generator, at one of four profiles (light, regular, heavy, stress) for a duration, and report the table: requests by route and status, p50, p95, p99, and the error ratio. Use to warm an environmen
ops-watchWatch one environment of the system live from a sub-agent: a log tail, the alarms as they fire, and the error and latency signals, batched per interval and capped, with a read-only credential. Run it in a sub-agent the invoking session spawns, because it polls for the whole window, at most 30 batche
stress-test-create-or-updateWrite or edit one stress test scenario of the system, ops/stress/<name>.yaml: the profile, the duration, the ramp, the soak, the target p95 and error ratio, and the routes it weights. States what a good stress test has and refuses to write one without a target. Writes a file and nothing else; a run
stress-test-runRun one stress test scenario of the system against one environment with the system's own generator, read the signals back through their own APIs, and report pass or fail against a target stated before the run: the scenario's p95 and error ratio, or the one the run states instead. A real run is the s
tickets-triageTriage the open tickets whose subject is this repository: for each, read it and check it against the code on main, the merged and open pull requests, and the history, then give it a verdict (done, moot, partly done, still relevant, in flight, out of scope, unsure) with the evidence. Writes a report;
arch-benchmark-browserRun the benchmark prompt in the chatgpt.com, claude.ai, gemini.google.com, and grok.com products, signed in, and save each answer with its conversation URL as proof; in a checkout of this repository, also check the run in, redacted, with its row.
arch-benchmarkRun a benchmark scenario (a skill, a command, or a question) in a declared runtime and have frontier models score it against the rubric. Use to measure a change to a skill or the text.
arch-deviateRecord a deliberate deviation from the guideline as an ADR under docs/adr/: the rule quoted, the decision, the consequences. Use when a finding is accepted as intentional.
arch-explainExplain how the guideline applies to a question, a file, or a change, citing the sections and lenses that govern it. Use when onboarding or before a cross-layer change.
arch-new-aspectIncorporate a new aspect into the guideline and cascade it through the lenses, skills, docs, and README, naming the release level. Runs in a checkout of the guideline repository.
arch-review-asyncArchitecture review through the Async lenses: infra, queues, workers, leases, park vs fail. For a change in this area, or as one leg of arch-review-full.
arch-review-contextArchitecture review through the Context lenses: stages, scopes, OperatorContext, authorization, tenancy, provenance. For a change in this area, or as one leg of arch-review-full.
arch-review-contractsArchitecture review through the Contracts lenses: interfaces, injection, wiring. For a change in this area, or as one leg of arch-review-full.
arch-review-deliveryArchitecture review through the Delivery lenses: apps, deployment, repo layout, client architecture, logs and telemetry, conventions, substitutions. For a change in this area, or as one leg of arch-review-full.
arch-review-fullFull architecture review: the eight lens groups of the guideline run in parallel and merge into one report. Use before a pull request, or when a change crosses layers.
arch-review-networkArchitecture review through the Network lenses: topology, gateway, public types, clients, realtime, push-first. For a change in this area, or as one leg of arch-review-full.
arch-review-omArchitecture review through the Object Model lenses: source of truth, mixins, immutability, identifiers, namespaces, pure rules. For a change in this area, or as one leg of arch-review-full.
arch-review-opsArchitecture review through the Operations lenses: roles, credentials, ops skills, alarms, scale-out, cost, environments, traffic, READMEs. For a change in this area, or as one leg of arch-review-full.
arch-review-storageArchitecture review through the Storage lenses: storage principles, tables, translation, roles, migrations. For a change in this area, or as one leg of arch-review-full.
arch-scaffold-appCreate a client app: the operator console, another browser app, or another command line, in the shape of the scaffold's portal and CLI, with its build, deployment, and tests. TypeScript or Python.
arch-scaffold-entityAdd one entity to an object-model namespace: the frozen type, the table and its migration with its policy, storage in Postgres and memory, manager operations, wire types, routes, a portal screen, and tests, in the shape of the scaffold's own. Python and TypeScript.
arch-scaffold-namespaceCreate an object-model namespace (a swimlane) with its first entity: the manager interface and impl, storage in Postgres and memory, its README, and the wiring into both roots, in the shape of the scaffold's own namespaces. Python.
arch-scaffold-newStart a new system in the guideline's shape: pick its name, copy the scaffold's domain-agnostic core under it, run its gates, record the product's first decisions, then add the first namespace.
arch-scaffold-serviceCreate a second web service beside the API: a domain service hosting some namespaces, or an app-specific service for one app, with its container, settings, routers, image, deployment, and tests, in the shape of the scaffold's API. Python (FastAPI).
arch-scaffold-workerAdd a kind of background work: the kind, its payload and permission, its handler in the maintenance worker or in a worker of its own, and the tests, in the shape of the scaffold's work queue and worker. Python.
arch-upgrade-depsUpgrade every dependency of the repository to its latest stable or LTS release (runtimes, tools, images, CI, Terraform, libraries), then run the gates and hold back what breaks.
arch-upgrade-scaffoldMove a copy of the scaffold, or a layer whose own scaffold builds on it, to a later release by merging it. The scaffold branch holds the scaffold as the repository took it, and a three-way merge brings in what changed since. The first run grafts a base at the release the repository pins, or takes a
arch-reviewerReviews a scope of code through exactly one lens group of the Software Design and Architecture Guidelines and returns the standard review report. Used by arch-review-full to run the eight groups in parallel; can be delegated to directly with a group name, a scope, and the absolute paths of the lens
